[web2py] Open menu item in new window.
In a view I have the following link which opens in a new window:
{{=A('Contact
form',_href=URL(r=request,a='utilities',c='forms',f='contact_form',args='init'),_target='_blank')}}
In a menu I have a menu item which references the same function:
['Contact
form',request.function=='contact_form',URL(r=request,a='utilities',c='forms',f='contact_form',args='init')]]
To keep their behaviour consistent I would like to open the menu item
in a new window also, is that possible?
Kind regards,
Annet.
Re: [web2py] Re: Anvanced applications in gae
Very interesting, i didn't know about collection_name and the associated query.
You are shedding some light on doing relationships the GAE way.
Thanks again.

Correction: the owner of pp4gae has just contacted me, saying he has "stopped working on this project since last update" and has given up on further work. Too bad. I have cloned the project at http://github.com/mdmcginn/pp4gae/ and have asked him if he could make me the owner of his Google Code project. Not that I know what I'm doing, but I could add competent coders as owners and could continue the project that way. Unless someone plans to release the blog code from KPAX soon...

[web2py] the best place to define custom widgets + extra info for widget
Hello, I found an example http://www.web2py.com/AlterEgo/default/show/170 and also studiet widgets in gluon.sqlforms a bit 1) now I make a separate file in /models probably I could make it in /modules but I need to make extra query to db in this widget 2) I want the options to be presented in hierarchical order like http://www.html-tags-guide.com/html-optgroup-tag.html (as I have tree structure for my topics in my system), the info about hierarchy is not present in "requires" what would be the best way to give this info to widget coud I make custom requires instruction?

[web2py] Re: WordPressClone/PyPress GAE fix

I'm now an owner of http://code.google.com/p/pypress4gae/ and http://github.com/mdmcginn/pp4gae, so if anybody else wants to work on this project, contact me.

[web2py] Re: upload bug in filename
Yes i am using web2py 1.79.2 on windows 7 64b Can someone try to save the web2py files in a very long directory name ( something like 200 characters ) and use the kind of filename i provided ( long ) and see what is happening on mac/linux? I am doing local tests only , it means that the file are on my local drive with these names so the fs can handle them properly. Python may have a pb or the admin interface code don t expect such a long FILEPATHNAME (base dir + filename ) .

Sorry - I replied a little too soon - I assume you _read_ this thread, and saw I tried your filename on mac, without problems. > > I am doing local tests only , it means that the file are on my local > drive with these names so the fs can handle them properly. > Python may have a pb or the admin interface code don t expect such a > long FILEPATHNAME (base dir + filename ) . The only thing I didn't post for you was the _file_ path name: /Users/me-123/workspace/web2py/tmptst/applications/ajaxdemo/uploads Add the filenames generated, as I put in previous posts, and you have your answer for mac snow leopard, at least. I do not think this has anything to do with admin interface code not handling length of filename, although there might be something that could be done about error detection (assuming the windows version file / os utilities are sending up an exception). Still - I question the IOError and generated filename you originally posted (I don't see any way that filename could have been generated from the web2py code, even if there were an error). If someone has access to a Windows 7, and is willing to try to reproduce this with a _clean_ web2py (I suggest the source version),please report details. Regards, - Yarko
[web2py] Newsletter apply form in every page by include, how?
Hi all, I have to {{include "sidebar.html"}} in every page of a site,
and one of the elements in this include is a little form (a text field
and a submit button) where user insert email address and apply for a
newsletter, effectively writing a record in db.newsletter. How can I
do this without a controller?
Also, there is a ready made example or appliance that can send a mail
to all email adresses present in a db table?

[web2py] Forms field spaced by option in db model?
Hi, something like this is possible? Automatic generation of forms by
db is just too lazy and beautiful to make me manually construct them
just for some space in between fields...
db.define_table('example',
Field('one'),
Field('two'),
Field('three'),
(insert a br here),
Field('for'),
Field('five'),
Field('six'),
(inser another br here),
Field('seven'))
This or something like css trick...

... you will want to send the form contents by ajax to a controller
which will do the saving; look at

Look at http://www.web2py.com/book/default/section/7/2 for an example.
If you use something like:
form = SQLFORM( db.example, formstyle='divs')
this generates a form using css classes, and you can modify the css to
get the effects you want.
You can see what this looks like with the shell:
python web2py.py -S welcome
>>> db = DAL('sqlite:memory:')
>>> db.define_table( 'example', Field('one'), Field('two'))
>>> form = SQLFORM(db.example, formstyle = 'divs' )
>>> print form

[web2py] bug in SQLFORM?
I have the following code: if form.accepts(request.vars, session): response.flash = int(form.vars.id) #id = int(form.vars.id) #doc = tb_documentos[id] #doc.update_record(estado=1) #redirect(url_expediente) elif form.errors: When you insert a record, the id should be about 30, but it returns enough numbers higher, but that does not follow any logic. For example 262826 and are not correlated. The row is inserted correctly. I do not know when it started to happen, I think that Thursday was working well. I regularly update web2py from the trunk. I was due to introduction of a bug. But download the stable version 1.79.2 and the problem continues. The database, which I do not administer, is MSSQL Server. I'll talk to the admin to see if there's something weird, but I doubt it. In my development machine with a test application and a database this works well. Someone has something similar?
[web2py] Re: bug in SQLFORM?
The id returned in the testing are: 263226 263228 263230 263232 263234 ... It is seen that increase in twos. If I go from the admin, the IDs are correct. Jose
[web2py] validators with dependencies
Alright, I'm burned out on trying to solve this.
I'm trying to make a form that checks if two fields match, like
password + verify password. I noticed in the book that there's an
example of this, but I can't seem to get it working. The code given is
as follows (this is with a typo correction, a quote is missing in
IS_EXPR in the book):
def index():
match_it = IS_EXPR('value==repr(request.vars.password)',
error_message='passwords do not match')
form = SQLFORM.factory(
Field('username', requires=IS_NOT_EMPTY()),
Field('password', requires=IS_NOT_EMPTY()),
Field('password_again', requires=match_it))
if form.accepts(request.vars, session):
pass # or take some action
return dict(form=form)
I run this code exactly, and while it works for displaying the page,
as soon as I submit the form I get the following error:
Traceback (most recent call last):
File "gluon/restricted.py", line 178, in restricted
File "E:/development/web2py/applications/informed/controllers/
users.py", line 23, in
File "gluon/globals.py", line 96, in
File "E:/development/web2py/applications/informed/controllers/
users.py", line 11, in index
File "gluon/sqlhtml.py", line 857, in accepts

File "gluon/validators.py", line 156, in __call__
File "", line 1, in
NameError: name 'request' is not defined
Now I imagine this is happening because the IS_EXPR code doesn't have
access to the request global. If this is the case, then how can I
achieve the result I'm looking for, and why is this example in the
book?
