[web2py] grid without
Hi, is there an easy way to use grid and smartgrid without the delete botton? I mean I want to only use the deleting option from the update form not the botton in the table because in this case no callback function are performed ( http://code.google.com/p/web2py/issues/detail?id=651) I've had a look of the SQLFORM.grid code in sqlhtml.py but at the moment I didn't realize how to solve it so I need to by pass. thanks Manuele

[web2py] Routes.py parameter, rewrite rules and redirect
Hi all, For one of my applications, I use web2py as a rest backend for a extjs application. So, in order to redirect to this app, I have def index(): example action using the internationalization operator T and flash rendered by views/default/index.html or views/generic.html redirect(URL(a=request.application, c='static', f='index.html')) The problem is I want to have only the server name in the url so I added a routes.py with routers = dict( BASE = dict( default_application = webmoni, applications = ['webmoni','admin'], controllers = 'DEFAULT' ) ) but it seems that the redirect neglects the default_application removal attempt from the url. How can I achieve this ? (not to have https://webmoni/webmoni/static/index.html as displayed url) Moreover, I did try the domains option but there were no way for me to get access to the admin app? Could anyone give an example with port 80 to app and 443 to admin using domains option ? Thanks in advance !!!

I'm now thinking of reading the db config from a config file in db.py but this

I'm facing the same problem as you (the 'all-in-one' solution doesn't fit
either) and the best solution I found so far was to read the DB connection
parameters based on a config file.
The drawback is that you have to read that file on each request... one day I'll
try to figure how to cache it.
An alternative might be a script that changed the URI in models/db.py, like this
one from Francisco Ribeiro:

Alternatively, you could keep it all in the same database with a

if you add a field such as the following to a table:

Field('request_tenant', default=request.host),
...
(where the default is however you identify the specific environment)
web2py will add a and request_tenant=''+request.host+'' to every query
relating to that table, and of course would insert it to new records.
Effectively, this means every record in a table with such a field will
only
be seen when the default value of the field in this request is the same as
when it was generated. (You can still get all records by either setting
the
default to None, or adding an ignore_common_filter=True)

The static 'controller' is a special case. It's not mapped by default, to make
it easier for external (server) rewrites. Add map_static = True to your router
to accomplish what you're after. (Also, 'static' can never be the default
controller.)
Moreover, I did try the domains option but there were no way for me to get

Could anyone give an example with port 80 to app and 443 to admin using
domains option ?
domains = {
domain.com:80 : app,
domain.com:443 : admin,
},
However, the stock /app/appadmin does things like this:
URL('admin', 'default', 'design', args=[request.application])
...and that will cause you problems, because it won't generate a secure access.
What ought to work in this example would be the following, in all cases in
which URL refers to admin (I haven't tested this):
URL('admin', 'default', 'design', args=[request.application],

If different domains go to dedicated web2py instances, there'd be no point in domain routing in web2py. Also, you might want to do your domain-to-application rewriting in the frontend server, in which case it wouldn't be useful in web2py. There's of course overlap between those two conditions.

Maybe. There are two reasons (that I can think of) why it might not. One is whether the frontend server is serving the requests to a shared instance (or set of shared instances) of web2py. If different domains go to dedicated web2py instances, there'd be no point in domain routing in web2py. Also, you might want to do your domain-to-application rewriting in the frontend server, in which case it wouldn't be useful in web2py. There's of course overlap between those two conditions. FWIW, from the router's point of view, Rocket is just another wsgi frontend server.
Re: [web2py] Returning JSON data to a GWT client app
yes... I've been using @service.json and my Pyjamas app can call such
decorated and retrieve json-formatted data. all I need to do is return
{'tag1', data1', 'tag2', data2}
I now want to know how I can get a GWT app to call the same function.
Anyone using GWT with Web2py?

Re: [web2py] Re: How to Represent a Foreign Key Using Foreign Keys in Primary Table
No dice. I think I'm going to take your original advice and build a

I see what you mean. In that case, you don't want to reference the other

For many to many relationships, you should have three tables.
table_one
table_two
table_relationship_between_one_and_two
But if you just want a list of the strings like so: '%(first)s -
%(second)s Against %(third)s'
What you wrote should work, based on what it says in the documentation,
the defaults should be sufficient. You can try this -- add:
db.table_two.requires=IS_IN_DB(db,table_one.id, db.table_one._format,
multiple=True)
That's just explicitly defining what should be the default...

[web2py] Deployment web2py Snow Leopard Server error
I am new to Web2py. I tried to deploy it on my Snow Leopard Server running Mac OS X Server 10.6.8. I have already installed on the server the wsgi module which I use with a Django app. I installed web2py on the server following the guidelines on the deployment chapter of the Web2py Book (4th ed).

Added the port 80 apache configuration lines to the web2py.mobility-br.com conf file using a include line; 6. restarted the web service. No error on the server.

I'm facing the same problem as you (the 'all-in-one' solution doesn't fit

The drawback is that you have to read that file on each request... one day

Alternatively, you could keep it all in the same database with a

https://groups.google.com/d/topic/web2py/CixV2qflqkk/discussion -
if you add a field such as the following to a table:
...
Field('request_tenant', default=request.host),
...
(where the default is however you identify the specific environment)
web2py will add a and request_tenant=''+request.host+'' to every
query
relating to that table, and of course would insert it to new records.
Effectively, this means every record in a table with such a field
will only
be seen when the default value of the field in this request is the
same as
when it was generated. (You can still get all records by either
setting the
default to None, or adding an ignore_common_filter=True)

Your model will be simpler like this ...
db.define_table('province',
SQLField('name', 'string', length=50, required=True,
default=None))
db.define_table('cities',
SQLField('name', 'string', length=50, required=True),
SQLField('id_province',db.province,
required=IS_IN_SET(db.province)))
db.define_table('customer',
SQLField('name', 'string', length=50, required=True),
# Removed id_province field
SQLField('id_cities',db.cities, required=IS_IN_SET(db.cities)))
The id_province field is redundant and unnecessary. If you wish to know a
customer's province, join the tables like this:
# request.args(0) contains the customer's id
((db.customer.id==request.args(0)
(db.customer.id_cities==db.cities.id)
(db.cities.id_province==db.province.id)
)

db.define_table('node', Field('parent',db.parent), Field('node_name'))
Tables will be maintained using smartgrid
The intention is to use jsTree or similiar loaded/ rendered from a JSON

(structure could get big so may need to look at some dynamic loading)
Was wondering if there is some sample code/ app that some one is will to
share to shed some light on which way to go?
