[IMPORTANT] 4.0.0-wip will be merged to master on 14th Feb, will break your existing installation

[Pratik Vyas]

Hi community,

We plan to merge 4.0.0-wip branch to master on Friday 14th February,
2014. The setup for 4.0.0 is diferent from version 3.x.x.
If you do not wish to migrate to 4.0.0, please switch lib and app
branches to 'release-3.x.x'. We will release install and migration steps
before that.


To switch branches,
```
cd lib && git fetch origin && git checkout release-3.x.x && cd..
cd app && git fetch origin && git checkout release-3.x.x && cd..
```
Also, please adjust your update commands accordingly.
ie.

`./lib/wnf.py --update origin release-3.x.x`
or
`wa deploy origin release-3.x.x`


Thanks,

Hi,

Now that the merge appears to have been perfomed, could you please provide some (very basic) instructions on how to run the new version?

I'm especially interested in directory layout, configuration, etc. as I've been trying to make the new version work for a couple of days without much success...

Thanks,

Billy

I'll be pushing the instructions after some testing in a few hours.

It should be easier to run this version. Are you also planning to
develop own apps on frappe?

i am currently trying to install erpnext by running 'install_erpnext.py' but it is giving following error :

 Installing Python Modules: (This may take some time)

Is it because of today's merging or something else. I am doing it first time so dont know how exactly it works.

can you try running the command manually?

sudo pip2.7 install chardet cssmin dropbox google-api-python-client

gunicorn httplib2 jinja2 markdown2 markupsafe mysql-python pygeoip
python-dateutil python-memcached pytz==2013d requests six slugify term
color werkzeug semantic_version gitpython==0.3.2.RC1

Today's merging shouldn't have caused this. You can also wait for
sometime and try out 4.0.0 as well.

Hi,

Actually, I don't doubt this version should be easier to run :-) I'm already sold on your engineering skills ;-)

I guess my concern was that there appeared to be a different repository layout. Now for some reason the webnotes repo has the same layout as before whereas the frappe repo has the layout I saw before. It's just a little confusing right now...

Anyways, I'll wait to get the instructions before trying to upgrade again.

About frappe apps, I might end up writing one app at some point, but not right now. Another thing that's a little confusing is what frappe exactly is. From my understanding, it looks like an evolution of webnotes that's meant to be more than a web framework in the sense that it's also a platform for apps. You seem to have a cloud offering for this, but my needs at this point are more towards running an heavily customized erpnext on-premise. Can I still do that with frappe or does it only work as-a-Service? An if so, how do I migrate an erpnext install (with some slight customizations to webnotes) from gunicorn to frappe?

Thanks,

Billy

Thank you for your kind words. :)

We've left the repositories in the webnotes organization of github as
per the version 3.x.x of wnframework and erpnext. All the new 4.0.0
stuff is in the frappe organization you saw.

Yes, exactly. Simply put, frappe is webnotes framework version 4.0.0
with a name change. With the new version of the framework, we've
removed the tight coupling within. The goal is to be able to extend
existing apps (best target is erpnext) and also be able to start new
projects. We've had such a pilot project in the past month and are
quite happy about the usablity/reusablity.

The cloud offering for frappe apps is a more generic cloud offering
than our current one for erpnext. You would still be able to customize
erpnext and run it in its entirety on your premise. No freedom
affected.

We'll be releasing documentation for that very soon. Also, I'd like to
highlight that this is a beta release, so migrating your production
system to ERPNext 4 is not a good idea as of now.

I am finalizing the install script at the moment. Will post when it's ready.

Thanks,

Hi,

Thanks for your answers!

So, if I understood correctly, frappe would allow me to run my heavily customized erpnext in the cloud. So in a way, this is more of a PaaS than a SaaS with modules. Good to know!

For this particular project, the requirement is that it remains on premise, though. The system isn't in production yet, but since that's scheduled for March/April, I'd rather upgrade sooner than later even if it means dealing with more bugs. Anyways, I have several copies of the environment in staging, so there's no real impact to users.

Thanks for the updated install script! Maybe you can answer one more question for me: Am I better off upgrading from an existing install or doing a fresh install and migrating then?

Well, not exactly. If your customization is a form of a frappe app,
we'd be happy to host in our app repository (with a proper
free/non-free license).

You can migrate to version 4 with existing data. Apart from wiring,
only permission system has changed.
