Greetings :)
Let's consider the following two models: -
class State(models.Model):
short_name = models.CharField(max_length=2, unique=True)
name = models.CharField(max_length=50, unique=True)
is_active = models.BooleanField(db_index=True)
def __unicode__(self):
return u'%s' % (self.name)
class Company(models.Model):
name = models.CharField(max_length=50)
contact_person = models.CharField(max_length=50)
email = models.EmailField()
address = models.CharField(max_length=255)
state = models.ForeignKey(State)
def __unicode__(self):
return u'%s' % (self.name)
The following form: -
class AttendToCompanyForm(forms.Form):
name = forms.CharField(max_length=50, widget=forms.TextInput(attrs=
{'class':'textInput',}))
contact_person = forms.CharField(max_length=50,
widget=forms.TextInput(attrs={'class':'textInput',}))
email = forms.EmailField(max_length=75, widget=forms.TextInput
(attrs={'class':'textInput',}))
address = forms.CharField(max_length=255, widget=forms.Textarea())
state = forms.ModelChoiceField(State.objects.filter
(is_active=True), widget=forms.Select(attrs={'class':'selectInput',}))
And the view: -
def attend_to_company(request, cid):
company_to_attend = Company.objects.get(id=cid)
if request.method == 'POST':
form = AttendToCompanyForm(request.POST)
if form.is_valid():
# some code
# some code
# some code
return HttpResponseRedirect(reverse('redirect-to-some-
page'))
else:
data = {'name': agencyrequest_to_attend.name,
'contact_person':
agencyrequest_to_attend.contact_person,
'email': agencyrequest_to_attend.email,
'address': agencyrequest_to_attend.address,
'state': agencyrequest_to_attend.state.id}
form = AttendToCompanyForm(data)
return render_to_response('attend_to_company.html', {'form':
form}, context_instance=RequestContext(request))
When I access the view via HTTP GET, if I use form =
AttendToCompanyForm(data) then the state field (a drop down select) in
the form is populated correctly and the corresponding state for the
company appears as selected in the list, but when I use form =
AttendToCompanyForm(initial=data) then the state field does not
reflect the corresponding state for the company, and instead shows the
first "-----" element of the drop down list.
Is this expected behavior? What is the cause of this?
Thanks and regards,
CM.
