py4web in Google App Engine route app

[Jacinto Parga]

I cannot properly deploy a simple py4web app in GAE. I think it's just a .gcloudignore or a app.yaml configuration issue. The only thing I've got is a not found page.

Some help about how to route the right app in the google app engine?

Thanks

[Christian Varas]

Hi I haven’t tried GAE but maybe is the controller.

Are you using the decorator ’action()’ to expose the function ?.

Ex:

@action('some_name')

def some_function():

  return locals()

Then you acces like http://IP/your_app/some_name

Cheers.

Chris.

No, thanks.

Finally it was a problem with the .gcloudignore

I had to get rid off every app but the one I wanted to deploy and the other unneccesary files to the GAE. The only thing left is that I need to add the name of the application to route the main domain to the proper app.

This is my .gcloudignore

# This file specifies files that are *not* uploaded to Google Cloud Platform

# using gcloud. It follows the same syntax as .gitignore, with the addition of

# "#!include" directives (which insert the entries of the given .gitignore-style

# file at that point).

#

# For more information, run:

#   $ gcloud topic gcloudignore

#

.gcloudignore

# If you would like to upload your .git directory, .gitignore file or files

# from your .gitignore file, remove the corresponding line

# below:

.git

.gitignore

#Ojo no se puede quitar requirements.txt

# Python pycache:

__pycache__/

# Ignored by the build system

/setup.cfg

.travis.yml

*.pyc

*.pyo

*~

#*

*.1

*.bak

*.bak2

*.svn

*.w2p

*.class

*.rej

*.orig

Thumbs.db

.DS_Store

./benchmark

./ssl

README.md

test-requirements.txt

source-context.json

password.txt

py4web-start.py

setup.py

And I'm using the default app.yaml may be this is the problem

runtime: python37

# Handlers define how to route requests to your application.

handlers:

- url: .*  # This regex directs all routes to main.bottle

  script: auto

So I had to write  the name of the application in the navigation bar: 

https://myapplication.appspot.com/aplicationname

In other case I get a not found page.

And it goes very very slow, it is only a login page.

Some help?

Your .gitcloudignore appears to be ignoring all of the apps:

apps/filemanager

apps/filemanager/*

apps/todo

apps/todo/*

apps/examples

apps/examples/*

apps/_dashboard

apps/_dashboard/*

apps/_scaffold

apps/_scaffold/*

apps/_minimal

apps/_minimal/*

apps/_default

apps/_default/*

apps/_documentation/*

apps/superheroes

apps/superheroes/*

[Jacinto Parga]

Yes. I've created a new application that is the only one I want to serve. In that case how can I  do in py4web the same thing I do with routes.py in web2py

Thanks

[Jacinto Parga]

Finally solved.

1. I add an entrypoint to the app.yaml . The app runs fine:
   runtime: python37

   entrypoint: gunicorn -b :8080 -w 2 main:app 

1. 
   

   
   

   # Handlers define how to route requests to your application.

   handlers:

   
   

1. - url: /.*

     secure: always

     redirect_http_response_code: 301

     script: auto


2. I get rid off all the apps but the default app and the app I want to deploy in the .gcloudignore:

1. # This file specifies files that are *not* uploaded to Google Cloud Platform

   # using gcloud. It follows the same syntax as .gitignore, with the addition of

   # "#!include" directives (which insert the entries of the given .gitignore-style

   # file at that point).

   #

   # For more information, run:

   #   $ gcloud topic gcloudignore

   #

   .gcloudignore

   # If you would like to upload your .git directory, .gitignore file or files

   # from your .gitignore file, remove the corresponding line

   # below:

   .git

   .gitignore

   
   

1. # Only ignore the default app and the app we want to deploy

   env/*

   env/

   !apps/*

1. apps/todo
   

   apps/todo/*

   apps/examples

   apps/examples/*

   apps/_dashboard

   apps/_dashboard/*

   apps/_scaffold

   apps/_scaffold/*

   apps/_minimal

   apps/_minimal/*

1. !apps/_default

   !apps/_default/*
   

   !apps/myapp

   !apps/myapp/*

   apps/_documentation/*

   apps/superheroes

   apps/superheroes/*

   apps/myfeed

   apps/myfeed/*

1. apps/*/databases/README*

   pps/*/databases/*

   apps/*/uploads/*

   apps/*/*.py[oc]

   packages/

   deployment_tools/*

   deployment_tools/

   tests/*

   tests/

   README.md

   test-requirements.txt

   source-context.json

   password.txt

   py4web-start.py

   setup.py

1. Makefile

   So when it is deployed in GAE http://myapp.appspot.com/ goes to _default/index.html url
2. I modify the __init.py__ file of the _default app to redirect to myapp folder:
   from py4web import action, __version__

   from bottle import redirect  #get redirect function from bottle

   
   

   @action("index")

   @action.uses("index.html")

   def index():

         redirect("/myapp")  # The former code: return dict(version=__version__)
   The result is that http://myapp.appspot.com/ serves http://myapp.app.com/myapp

Maybe there is a more elegant way to get it. Any suggestion would be appreciated.

Thanks

This is a good solution. One trick is to symlink _default to myapp

[Jacinto Parga]

Yes, but I get an error with symlink in __init.py__ of _default: 

from py4web import action, __version__

import os

@action("index")

@action.uses("index.html")

def index():

    src = "/_default"

    dst = "/myapp"

    os.symlink(src, dst)

    return dict(version=__version__)

[Massimo Di Pierro]

There are two problems here:

1) you cannot symlink in an action because it must be done once and only once.

2) You cannot have paths like /_default because they are absolute paths

Assuming this is a linux or OSX machine you should do from the shell

$ rm -rf apps/_default

$ ln -s apps/myapp apps/_default

You only need to do this once.

[Jacinto Parga]

Thanks, perfect!! It's better.

I have some apps deployed in GAE, with web2py pyhton 2.7. I want to migrate them to python 3.7, but cannot deploy web2py python 3.7 on GAE. I wonder if stable version of py4web will take too long or if it is better to try to find out how to deploy web2py python 3.7 on GAE
