I git installed web3py and quite enjoy it. I see its updated regular too. 

For those who don't know and maybe this is common sense , not sure. 

once you git clone https://github.com/web2py/web3py.git  do a git pull

2. reinstall requirements.txt (pip3 install -r requirements.txt) 
 - Changes:  module "reloader" was added 

3. Launch web3py (should work just fine now) 
 python3 web3py.py applications/todo/

4. open browser and type:  localhost:8000 or 127.0.0.1:8000/todo/index

There is a lot to do but at this point it is moving fast and a one way street.

Any thoughts on merging / collaborating with weppy?


Uses web2py dal and yatl..
and has some nifty things to make queries and modelling easier..

I'm trying to wrap my ahead around how web3py works by looking at the source 

I see __init__.py is the main code for the actually todo app. 

Is this going to be the case for all applications ? or is this just for a sample ?

In web3py an application is a folder, for example "myapp". It must have:

applications/
  myapp/
    __init__.py
    templates/
    static/
    databases/

otherwise the structure is free. You are free to create models/ and controllers/ and organize code like in the old web2py but the entry point is __init__.py. Web3py will see functions defined in __init_ or imported by init. In my examples I defined all actions in __init__. For example

In __init__.py =============
from . import models
from . import controllers

In model.py =============
from web3py import DAL, Field
db = DAL('sqlite://test')
db.define_table('thing', Field('name'))

In controllers.py =============
from web3py import action, request, redirect, abort
from . models import db
@action('helloworld') # exposes http://127.0.0.1:8000/myapp/helloworld
@action.uses(db, 'helloworld.html')
def helloworld(): return dict(name=request.forms.get('name', 'visitor'))

In templates/helloworld.html =============
[[extend 'layout.html']]
<h1>Hello Dear [[=name]]</h1>

In templates/layout.html =============
<html><body>[[include]]</body></html>


request, redirect, abort are Bottely objects
DAL, Field are web2py's
the template is the same as web2py but defaults to [[ ]] delimiters to avoid conflicts with vue.js and other js
the @action decorator accepts the same parameters as bottle.route but does a little more.
There is also a form.py that implements Form() a drop in replacement (to be tested) for SQLFORM.

Notice we do all of this in 300 lines of python code and 10x faster than web2py in my tests.

Working on admin and appadmin. May be done in one week.

May steel some ideas from weppy but I do not want an ORM. That can be optional if you like we can isolate it in a module.

I reaaaaaaly would like to use an ORM with web3py, in my opinion ORMs are better for organization when apps grow big and I like a lot the fat models and thin controllers approach, and it is some messy with pydal right now (https://github.com/Medisur/journalmanagement/blob/master/models/citation.py). I have isoleted the weppy ORM some days ago (as hobby), it's not fully tested, and will need some refactoring, but if you are interested I can share it.

Greetings.

Can you make it a module on pypi? Or should we include it in pydal?

Geat progress Massimo.

Looks awesome!

I take it we stick to bottle then and embrace vue.js as the default frontend of choice.

I suppose on the long run we just have to think about some standard glue code generation that also works with Auth and jwt on the rest endpoints. Possibly swagger / openapi auto Generation as a plus. 


Wish I would not be such a noob at coding but maybe I can look into some of it.

perhaps can learn the concept from popphp, seems make it modular e.g.
pop-form
pop-auth
etc ...
ref:

just an idea : 
web2py decomposed into small module with css or frontend agnostic that work only in python3 = web3py

def helloworld(): return dict(name=request.forms.get('name', 'visitor')) # change visitor into another value e.g. guest, ended must restart server to take effect in browser http://localhost:8000/myapp/helloworld, is it normal ?
in another thread (web3py again) report about new app created must restart server, in this test, the app called myapp already loaded in web server, just change the value, must restart the server too, not sure if this acceptable behaviour

You say "web2py decomposed into small module with css or frontend agnostic that work only in python3 = web3py"

yes. that is the idea.

The example apps that come with it are not going to be frontend agnostic.

You have an old version of pydal. The new pydal may not be on pypi, may need to get it from gitbub. I will post it on pypi over the week-end

perhaps it related with pydal is not released yet on pypi, btw, this is the step i took to reproduce the traceback above
rm -rf ~/learn/python/web3py
cd ~/learn/python
git clone https://github.com/web2py/web3py
source activate python3_test
cd ~/learn/python/web3py
pip install -r requirements.txt
python web3py.py applications/
open http://localhost:8000/todo/index

the bolt command should updated the pydal, isn't it ? or should i run it with 
pip install -U -r requirements.txt

no worries for scaffolding app that come with css or frontend embeded, what i mean of agnostic is something like sqlform or sqlform.grid(). the sqlform.grid() is great to help build web app faster, but not flexible because glued with only bootstrap framework, perhaps if you can make it work with another frontend framework, that would be nice to have.

seems Makefile and setup.py not working yet, installed dependencies should using pip3 install -r requirements.txt

also in the thread '50x performance improvement for web2py in TechEmpower Web Framework Benchmarks', wondering web3py (which 10-20x faster) compare to the optimized web2py (50x performance improved) on techempower benchmarks. perhaps can learn from that code.

added parameter for logging the app or server would be nice in web3py-start, problem found is when try to analyze the root cause during the test in docker. checked in docker logs, there is no logs, when try the interactively inside web3py folder and /var/log/ there is none of the log tell about what's going on happen.

nice dashboard, only myapp can work from dashboard link
some strange behaviour, when accessing dashboard (without index), it automatic add dashboard/static/index.html, while for another web app is not, must add index manually.

sorry forgot to test about docker-compose (not work either, guess the problem is on web server side, hard to trace because no log provided yet both on web3py folder or in /var/log/)

after learn the code web3py/web3py/core.py
python3 /web3py/web3py-start /web3py/applications/ is automatically run the address 127.0.0.1:8000
so the correct one to make it run on docker should use :
python3 /web3py/web3py-start /web3py/applications/ --address 0.0.0.0:8000

think there are two options
first change the default address on core.py
from
parser.add_argument('--address', default='127.0.0.1:8000',help='serving address')

into
parser.add_argument('--address', default='0.0.0.0:8000',help='serving address')

or second choice
change the CMD path for docker and add the parameter address
python3 /web3py/web3py-start /web3py/applications/ --address 0.0.0.0:8000

so Dockerfile tested work
cat << EOF > Dockerfile
FROM ubuntu:latest

RUN apt update && \
 apt install -y git python3-pip && \

for docker image base, python image base take > 200 mb while another os < 100 mb, your choice.

You have an old pydal. Do

pip3 install --upgrade pydal

Also do

python3 web3py.py applications

Not

python3 web3py.py applications/todo/

Vuetify is designed specifically for vuejs

As someone who had some SQL training (but not proficiency) before  using Web2Py,
and who has rarely had an issue with using the DAL (but then, I don't have complicated projects, either),
I could use some info on what makes an ORM great.

I know that Massimo has said in the past that it was a deliberate choice to do the DAL instead of an ORM
(is the DAL a DAO?),
and I see the contributors to Wikipedia have listed some concerns
along with the advantages
(client code gets to stick with working with objects ++
 high level of abstraction obscures what is happening --
 heavy reliance on ORM cited as major factor in poorly designed DBs --)

The third approach appears to be OODBMS where the store actually is built around objects via ODMs
rather than translating tables.  This gets into NoSQL territory, it seems.

So, educate me!

As almost everything in our world ORMs has advantages and disadvantages. The main criticism about ORMs is that they are leaky abstractions, that means they leaks details that it is supposed to abstract away, because there are times when you just need to use, for example, SQL directly or work with raw rows when making complex queries or improving performance because that is one of the ORMs disadvantages, they include an extra logical layer that, depending on the implementation can affect performance more or less.

But there are lot of people out there using ORMs and this is because they have advantages, compared with PyDAL, mostly when you are using big models, for example, compare this PyDAL model:

    def _get_somethig_plus_age(row, extra):
        return row.person.age + extra

    db.define_table('person',
        Field('name')
        Field('age', 'integer')
        Field.Method('get_somethig_plus_age', _get_somethig_plus_age)
    )

against this ORM-style model:

    class Person(Model):
        name = Field()
        age = Field('integer')

        def get_somethig_plus_age(self, extra):
            return self.age + extra

In an ORM, a model class represents a table, and when you query the DB, you get the class instance objects representing rows. Using this approach you can directly benefit from the advantages of the OOP and the code readability and organization improves a lot, mostly when models starts grow big.

Greetings.

I think one of the reasons web2py is so productive and has an easy learn curve is due to the fact of using DAL instead of an ORM.
I don't see any problem in using sqlalchemy with web2py if an ORM is needed.  I would probably use it in some big projects for some of the models.

But for the sake of the easy learning/productivity/quick development time I would prefer to keep pydal as the default, at least for the features web2py provides (auth, security, etc.)
Just my 20 cents.

In the case of the weppy ORM in particular, though, I think it really is just alternative syntax for everything that can already be done via pyDAL, typically with the same number of lines of code (note, the above examples would have the same number of lines if you added the @rowattr('get_something_plus_age') decorator required by weppy to the instance method).

My only concern is whether the benefits are worth having to adopt all that new code (and update it when changes are made to pyDAL). Maybe it should remain an external package rather than being folded into pyDAL.

Well, that's a really fair concern, I was just mentioning, because I like ORMs and other popular projects like SQLAlchemy includes a DAL (they call it SQL abstraction toolkit) and an ORM on top of it, and if you look at popular web development full stack frameworks, almost all of them are relaying their models to ORMs.

I've just been playing with web3py and I think it's great!  This framework seems so much cleaner and I like the Bottle routes etc.

Re: Dashboard. Currently broken, but I guess Massimo is still working on this and committed prematurely.

Re: ORM.  It feels like we are talking about the icing before the cake has been mixed. Hopefully any ORM would just be a plug-in option rather than weighing down our fantastic DAL.

Re: Auth.  This seems a much more important topic because I'm not going to bother making any app until I know how to secure it. This is one feature of web2py that is vital.  I'm really hoping too that any auth would include 'roles' because 'authorization' depends on that. I hope this will attract more comments.

Re: Form. I know that we want to be agnostic, but there seems little harm to include basic styling classes. Could this be taken from a config file?  Maybe Vuetify would be better than Bootstrap?

Re: Grid.  I use SQLFORM.grid for prototyping,  but I then I so often find myself replacing that code with Datatables. Shouldn't we just include Datatables?  It has everything we need - doesn't it?

Thanks to Massimo and others for making this great progress for our community!

web2.py existed before web2py and did not hurt us.
web3py existed before web3.py and in fact I own the domain name. It will not hurt us either.

I am more concerned by the confusion between web2py for python 3 vs web3py.
I am thinking it should have two names "web3py XYZ" where XYZ is t.b.d.

At least with the example given, I don't see a lot of difference in organization or readability (particularly not enough to warrant introduction of the ORM codebase as well as the confusion that can come with having multiple ways to do the same thing).

The SQLAlchemy ORM adds a lot of functionality that is not available with its DAL alone, and most of that extra functionality already exists in pyDAL. As far as I can tell, the weppy ORM does not really add any functionality to the DAL -- it is mostly an alternative syntax. I'm not saying there isn't value there, just that it is a lot of code maintenance to take on for maybe only a very modest benefit.

If you made use of SQLHTML forms and grid and simply want to move from python2 to python3, than stick with web2py.

If you want to use the DAL and maybe web2py templates but your app is (or will be) using mostly API driven then use web3py.

web3py already supports tickets (like web2py), pydal, yatl, helpers (almost identical to web2py), multi app (applications folder), and will soon have a functioning _dashboard (with similar functionalities to web2py's admin+appadmin). You will be able to develop and deploy and manage apps very much like you do in web2py. What we will not do, is encourage the use of server side rendering of forms and grids with postbacks logic that web2py has. We will instead create more tools to make API based apps easier to build with minimal JS programming. web3py will be less opinionated on the server but more opinionated on the client. It will not force you to use any client specific JS but default apps will ship with vue.js and examples based on vue.js.

The goal is the same "make web development easy and enforce good practices" but the web has changed since 2007, when web2py was designed.

I have been looking more into veutify. I have some reservations.
I think a good CSS framework (for web3py) should be JS agnostic, even if the examples use vue.js.
I think effects should be done in CSS only, not in JS. vuetify does not follow this rule.
Also vuetify is really designed for use with the CLI and I would like web3py to remain CLI agnostic.
Documentation is not good yet.
I think I will stick to bulma for now for the simplest example apps and dashboard.

For mobile app style, I like Framework7 a lot.

scaffolding app would be nice to have example of authentication (user registration, login and logout) and to update the data, e.g. update todo list on todo app
just wondering, if form used manually using javascript, is the field validation on pydal, still can work ? e.g. requires=IS_NOT_EMPTY()

Authentication + authorization and documentation of endpoints are actually the hardest part.

There is a. Flask based framework called connexxion which asks you to create the openapi spec before the code which has jwt and oauth2 build in as. Well. 


Then there are flask Rebar which can use jwt and auth0 build in . Also gernatrss openapi 2 documentation.

And there is Sars., also a Flask based framework thst generates openapi 2 documentation and can easily extend with jwt and oauth2 via flask plug-ins.

There is also hug, based on the falcon framework.. Also generates openapi v2 documentation and has an oauth2 plugin and does jwt build in. 

Thus I was thinking to bring up this topic early. 

Bottle does not have this kind of out of the box suopport, but there is a framework agnostic openapi generator we could use : https://apispec.readthedocs.io/en/stable/

And we could create a oauth2 plugin for bottle (the current one is deprecated) based on authlib. 
Authlib also has the ability to generate jwt tokens, but for standalone tokens we could use pyjwt I guess. 

When we scaffold crud apis and vue frontends with authentication in place thst would be great just as it was with web2py by just using a decorator I. E. Crud api routes and functions and authentication via tokens and/or oauth2. 

The openapi makes it easy to collaborate with others in Microservice environment and also gives users the ability to generate UIs sich as with angular and react based on openapi specs Web3py generated for thr enpoints.

I was wrong.. Found a recent integration with bottle  and oauthlib.. 

Now we only need to figure out jwt and easy rest crud.. Which bottle is perfect for and finally use the before mentioned openapi generator with bottle and we are good to go.

I will work on auth.

I could use some help with _dashboard. The "create app", "upload app" and "pack app" buttons do not work but this logic should work the same as in web2py. Should be easy to backport if somebody can help this week.

error in dashboard seems there is no index.html file on /_dashboard/static/index.html, which is occured in previous commit
want to help n learn, but not sure is it same to learn it from web2py/applications/admin/controllers/appadmin.py can be apply to web3py/applications/_dashboard/__init__.py ?

my mistake. I added it.

the web2py admin is different. The web3py one is much more spartan. But the functions that need to be ported to zip/unzip apps are indentical.

not sure got the meaning of spartan
tested last commit, all errors above gone (_dashboard and _scaffold)
just a note for default requirements.txt for guncorn, seems it can't run windows, is it design that way ? 
another alternatives run on windows n *nix environment : waitress or rocket (same like web2py)

"spartan", "spare", and "barebones" all have senses relating to mimimalism (in a general sense, not just Terry Riley's music) and lack of frills or extras.  "Spartan", of course, is derived from the ancient Greek nation-state, whose populatiion was encougraged to be tough, avoid excess, and be ready to bear hardship.

Massimo is saying that the web3py admin (dashboard?) has enough features to be useful, but doesn't include cupholders and leather seats.

I followed these directions as best I could:

* There is no file named web3py.py.  There is a file web3py-start; that seemed to work
* No matter what URL I provide, I get a big red screen saying "404 Not Found"

For those who don't know and maybe this is common sense , not sure. 

once you git clone https://github.com/web2py/web3py.git  do a git pull

2. reinstall requirements.txt (pip3 install -r requirements.txt) 
 - Changes:  module "reloader" was added 

3. Launch web3py (should work just fine now) 
 python3 web3py.py applications/todo/

4. open browser and type:  localhost:8000 or 127.0.0.1:8000/todo/index

yeah you right, pls follow this step instead (for latest commit)
git clone https://github.com/web2py/web3py
cd web3py
pip install -U -r requirements.txt
python web3py-start applications/

for url return 404, perhaps you can check on the applications folder, in the webapp name, you could learn from __init__.py file the url that is valid. some of __init__.py is load another module file controllers.py.
pls check at the top of the function name:
e.g. pls change examples with appname you want to access
applications/examples/__init__.py
@action('form', method=['GET','POST'])
so it means the url valid is http://localhost:8000/examples/form

You may not need that last "python".
The instructions in the README.md file downgitloaded worked fine for me, and I have 2 items in the todo list.

I have been looking more into veutify. I have some reservations.
I think a good CSS framework (for web3py) should be JS agnostic, even if the examples use vue.js.
I think effects should be done in CSS only, not in JS. vuetify does not follow this rule.
Also vuetify is really designed for use with the CLI and I would like web3py to remain CLI agnostic.
Documentation is not good yet.
I think I will stick to bulma for now for the simplest example apps and dashboard.

For mobile app style, I like Framework7 a lot.

Is stupid.css a dead end?  Too much re-inventing the wheel?

stupid was an experiment. the _dashboard is based on some variation of it. I do not think it good enough for what people expect from a css framework today. The collection of pure css effects in there has some value but that's all.

the error above seems related to the module not installed yet, there is a different between pip and pip3 in conda environment, yet the environment already active with source activate python3_test but it still detected the conda base environment
$ pip -V
pip 19.0.3 from /Users/sugizo/miniconda3/envs/python3_test/lib/python3.7/site-packages/pip (python 3.7)
$ pip3 -V
pip 19.0.3 from /Users/sugizo/miniconda3/lib/python3.6/site-packages/pip (python 3.6)

realize it with pip list or pip freeze to check the module installed, my bad

Fixed a bunch of issues, improved the examples, and ticketed what needs to be done (not much).
I assigned some to me but I could use some help.

You could call it web2py3 with this logic
web2py was web for Python (at the time it was Python 2.x)
web2py3 will the web for Python 3.

web3py existed before web3.py and in fact I own the domain name. It will not hurt us either.

I am more concerned by the confusion between web2py for python 3 vs web3py.
I am thinking it should have two names "web3py XYZ" where XYZ is t.b.d.

Yeah saw that too.

I agree it's worthwhile to go for a different name eventually.

Note: if the folder, translations, that is being complained about is added, the app still can't be reached, but there is no longer an exception reported: just the 404 page.
