Chris, this is something I was working on, based on the t2.pdf
example... See if it is of any use to you. The indentation will be
screwed up pretty badly, I'm afraid...
These instructions replicate the puppy example in the
T2.PDF docs, pages 7-11, for the new tools.py
environment in web2py 1.56
0. From the admin interface, add new app 'puppy'
1. Define table 'puppy' and create a crud instance
# db.py:
db.define_table('puppy',
SQLField('name'),
SQLField('image','upload') )
db.puppy.name.requires=IS_NOT_EMPTY()
from gluon.tools import Mail, Auth, Crud
crud=Crud(globals(),db)
2. Enable a RESTful interface through crud
# controllers/default.py:
def data():
return dict(form=crud())
def download():
return response.download(request,db)
3. Go to http://localhost:8000/puppy/default/data/create/puppy
to see a 'create puppy' form and play around with the default CRUD
interface
4. Create a template for the CRUD pages
# views/default/data.html
{{extend 'layout.html'}}
{{=form}}
<p>You are now using the data.html template.</p>
...and retry the CRUD URLs; the nice admin/session/etc buttons showed
earlier should be missing now...
5. Define a combo page that shows items + a create form
# views/default/customcreate.html
{{extend 'layout.html'}}
<div class="frame">
<h2>Post the image of a Puppy</h2>
{{=form}}
</div>
<div class="frame">
<h2>Puppies</h2>
{{=items}}
</div>
<p>You are now using the customcreate.html template.</p>
# controllers/default.py
def customcreate():
form = crud.create('puppy')
items = crud.select('puppy', linkto=URL(r=request,f='data',args=
['read']))
return dict(form=form, items=items)
6. Optionally include the "search" widget from t2.py?
(see t2.pdf, page 9)
(the high-level stuff such as search, comments, etc has gracefully
been split out of tools.py)
7. Add authentication
# in models/db.py:
# define your own auth_user table so you can extend it later...
# you can also set auth.settings.table_user later, but you may lose
users already registered (?)
db.define_table('auth_user',
SQLField('first_name',length=32,default=''),
SQLField('last_name',length=50,default=''),
SQLField('email',requires=IS_EMAIL()),
SQLField('password','password',requires=CRYPT()),
SQLField('registration_key',length=64),
SQLField('pic','upload',default='')) # and add any field you
want...
auth=Auth(globals(),db)
auth.settings.table_user=db.auth_user
auth.define_tables()
# in controllers/default.py:
def user(): return dict(form=auth())
# and add a menu so we can see state
if auth.user: response.menu=[
['logout',False,URL(r=request,f='user',args=['logout'])]]
else: response.menu=[
['login',False,URL(r=request,f='user',args=['login'])],
['register',False,URL(r=request,f='user',args=['register'])]]
Go to http://localhost:8000/puppy/default/user/register to register as
a user.
Go to http://localhost:8000/puppy/default/user/login to log in.
8. Now restrict access to these puppies to logged in users
# in controllers/default.py:
@auth.requires_login()
def data():
return dict(form=crud())
@auth.requires_login()
def download():
return response.download(request,db)
@auth.requires_login()
def customcreate():
form = crud.create('puppy')
items = crud.select('puppy', linkto=URL(r=request,f='data',args=
['read']))
return dict(form=form, items=items)
(Note: the T2 requires_login had the option of specifying a 'next'
function which
was passed in the vars._destination... This is missing in tools for
now, AFAICT)
---
I don't use the authorization stuff yet, powerful as it is, so I'll
leave this to someone else.
For myself, the next stop is subclassing Auth... one reason being to
adapt email registration.
Cheers,
-Peter
