Hello,
I made a lot of progress, by changing my approach, instead of trying to use
Autocomplete form SELECT_OR_ADD_OPTION, I bring SELECT_OR_ADD_OPTION into
Autocomplete to create a new AutocompleteWidgetSelectOrAddOption widget...
What I get so far :
class AutocompleteWidgetSelectOrAddOption(object):
_class = 'string'
def __init__(self, request, field, id_field=None, db=None,
orderby=None, limitby=(0,10),
keyword='_autocomplete_%(fieldname)s',
min_length=2,
# SelectOrAddOption
controller=None, function=None, form_title=None,
button_text = None, dialog_width=1000):
self.request = request
self.keyword = keyword % dict(fieldname=field.name)
self.db = db or field._db
self.orderby = orderby
self.limitby = limitby
self.min_length = min_length
self.fields=[field]
if id_field:
self.is_reference = True
self.fields.append(id_field)
else:
self.is_reference = False
if hasattr(request,'application'):
self.url = URL(args=request.args)
self.callback()
else:
self.url = request
# SelectOrAddOption
if form_title == None:
self.form_title = T('Add New')
else:
self.form_title = T(form_title)
if button_text == None:
self.button_text = T('Add')
else:
self.button_text = T(button_text)
self.dialog_width = dialog_width
self.controller = controller
self.function = function
def callback(self):
if self.keyword in self.request.vars:
field = self.fields[0]
rows = self.db(field.like(self.request.vars[self.keyword]+'%'))\
.select(orderby=self.orderby,limitby=self.limitby,*self.fields)
if rows:
if self.is_reference:
id_field = self.fields[1]
raise
HTTP(200,SELECT(_id=self.keyword,_class='autocomplete',
_size=len(rows),_multiple=(len(rows)==1),
*[OPTION(s[field.name],_value=s[
id_field.name],
_selected=(k==0)) \
for k,s in
enumerate(rows)]).xml())
else:
raise
HTTP(200,SELECT(_id=self.keyword,_class='autocomplete',
_size=len(rows),_multiple=(len(rows)==1),
*[OPTION(s[field.name],
_selected=(k==0)) \

enumerate(rows)]).xml())
else:
raise HTTP(200,'')

This also needed :
@auth.requires_login()
def add_eregistry():
#this is the controller function that will appear in our dialog
crud.settings.formstyle='divs'
form = crud.create(db.ref_eregistry)
for i in range(0,len(form[0])):
if len(form[0][i][2][0]) > 0:
form[0][i][0].append(SPAN((helpicon(),
SPAN(form[0][i][2][0])),_class='tooltip'))
del(form[0][i][2])
if form.accepts(request.vars):
#Successfully added new item
#do whatever else you may want
#Then let the user know it worked
response.flash = T("Added")
target= request.args[0]
#close the widget's dialog box
response.js = '$( "#%s_dialog-form" ).dialog( "close" ); ' %(target)
#update the options they can select their new category in the main
form
response.js += """$("#%s").append("<option
value='%s'>%s</option>");""" \
% (target, form.vars.id, db(db.ref_eregistry.id==form.vars.id
).select(db.ref_eregistry.eregistry_id).first().eregistry_id)
#and select the one they just added
response.js += """$("#%s").val("%s");""" % (target, db(
db.ref_eregistry.id==form.vars.id
).select(db.ref_eregistry.exp_num).first().exp_num)
#finally, return a blank form incase for some reason they wanted to
add another option
return form
elif form.errors:
#silly user, just send back the form and it'll still be in our
dialog box complete with error messages
return form
else:
#hasn't been submitted yet, just give them the fresh blank form
return form
The only remaining problem I have is that I can't get the new created entry
in the foreign table to be attach to the new record because the way I pass
the foreign key to the Autocomplete box... I put the problematic lines in
red in the code above...
I think, I am not using the proper selector or there is something wrong
with the callback, it may be not trigger the way I pass the foreign
record...
