Chris,
I hope you don't mind me bothering you again, but your posts made me
reconsider other parts of my applications as well.
I now have a module widgets.py:
from gluon.sqlhtml import *
def timeplain(field,value):
if value == None:
value = ''
elif 'strftime' in dir(value):
value = value.strftime('%H:%M')
id = '%s_%s' % (field._tablename, field.name)
return INPUT
(_type='text',_id=id,_class='time_plain',_name=field.name,value=str
(value),requires=field.requires)
.. and a model which contains the following lines of code:
from applications.demo.modules.widgets import*
widget=timeplain
On Mac OS X Leopard Server I did not have to restart the server, it
worked right away.
>From this I learn that I could also import the widgets from one
application into the other. Which means I could create the widgets.py
file in a parent application's module folder and move the widgets from
its child applications into that widgets.py file. Right?
In two of my applications I created a handlers.py controller
containing functions that handle auto_completion. In a function in a
controller I have:
form=form_factory(SQLField('place',requires=IS_NOT_EMPTY
(),widget=lambda self, value:INPUT
(_type='text',_id='clubbyplace',_class='ac_input',_name='place',requires=self.requires)))
... in web2py_ajax.html:
$('#clubbyplace').autocomplete('/core/handlers/clubbyplaceAC',
{maxItemsToShow:12});
... and in handlers.py
def clubbyplaceAC():
q=''
if request.vars:
q=request.vars.q
if not q:
return q
rows=db((db.adres.bedrijf==db.bedrijfinschrijving.bedrijf)&
(db.bedrijfinschrijving.inschrijving==2)&\
(db.adres.plaats.like('%s%%'%q.capitalize())))\
.select(db.adres.plaats,orderby=db.adres.plaats,distinct=True)
r=''
for row in rows:
r='%s%s\n'%(r,row.plaats)
return r
Based on what I've learned today, I assume I could create a
handlers.py file in the parent application's modules folder:
from gluon.sqlhtml import *
def clubbyplaceAC():
q=''
if request.vars:
q=request.vars.q
if not q:
return q
rows=db((db.adres.bedrijf==db.bedrijfinschrijving.bedrijf)&
(db.bedrijfinschrijving.inschrijving==2)&\
(db.adres.plaats.like('%s%%'%q.capitalize())))\
.select(db.adres.plaats,orderby=db.adres.plaats,distinct=True)
r=''
for row in rows:
r='%s%s\n'%(r,row.plaats)
return r
... change the line of code in web2py_ajax.html to read like:
$('#clubbyplace').autocomplete('applications/parent/handlers/
clubbyplaceAC',{maxItemsToShow:12});
... somehow rewrite the widget: widget=lambda self, value:INPUT
(_type='text',_id='clubbyplace',_class='ac_input',_name='place',requires=self.requires))
.. to read like:
def clubbyplace(field,value):
if value == None:
value = ''
id = field
return INPUT
(_type='text',_id=id,_class='ac_input',_name=????,value=str
(value),requires=self.requires)
... and put it the widgets.py
... in the model of my application:
from applications.parent.modules.widgets import*
... and in the function:
form=form_factory(SQLField('place',requires=IS_NOT_EMPTY
(),widget=clubbyplace(clubbyplace,???)))
I gave it a try, but I don't get the widget right. I hope you will
help me to get this to work.
Kind regards,
Annet.
