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.
