When text is typed that is not in the list and submitted there is this error:

Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: ''

Is this supposed to have built in validation?

 Here is some real magic now in trunk that I am sure you have never
 seen.

 Caveats:
 0) requires latest trunk (bzr 1603, hg 175:e42b559254f6)
 1) this is an experiment, not sure it is a good idea
 2) this is the first function in web2py that REQUIRES jQuery
 3) works but I am not yet convinced it should stay there
 4) even if it stays, I am sure the API should stay

[web2py] AutocompleteWidget: experimental, magic, RFC

2010-02-06 Thread mdipierro 
People say there is some magic in web2py.
Here is some real magic now in trunk that I am sure you have never
seen.

Caveats:
0) requires latest trunk (bzr 1603, hg 175:e42b559254f6)
1) this is an experiment, not sure it is a good idea
2) this is the first function in web2py that REQUIRES jQuery
3) works but I am not yet convinced it should stay there
4) even if it stays, I am sure the API should stay

Example:

### assume this model
db.define_table('target',Field('name'))
if not db(db.target.id0).count():
db.target.insert(name=Klingon)
db.target.insert(name=Romulans)
db.target.insert(name=Borg)
db.target.insert(name=Borg2)
db.define_table('photon_torpedo',Field('target',db.target))

### assume this action in controller default.py
def launch():
db.photon_torpedo.target.represent=lambda target: target.name
return dict(new_torpedo=crud.create(db.photon_torpedo),
launched_torpedos=db().select(db.photon_torpedo.ALL))

So far nothing new.

Now append to the model or insert at top of controller the following:

from gluon.sqlhtml import AutocompleteWidget
db.photon_torpedo.target.widget=AutocompleteWidget(request,db.target.name,db.target.id)

No need to define any callback action (there is no callback action!)
No plugin required (perhaps some optional css to style).
No js coding required.
Applies to existing apps, including those that use custom forms.

Let's see who can figure out how it works!

I have my current autocomplete but it doesn't do öäå in a search.  Does
this handle that?
Best Regards,
