Re: Vs: how to override a ModelChoiceField in order to add FKs directly in a TextInput?

Hi, Martin. Thanks for your reply. I wound up using IntigerFields and getting around the "relation must be an instance" error by adding clean methods that returned instances, e.g. def clean_myfield(self): data = self.cleaned_data['myfield'] data =

how to override a ModelChoiceField in order to add FKs directly in a TextInput?

I can get text inputs rendered fine by setting the widget to a TextInput like so: myrelation = ModelChoiceField(MyRelatedClass.objects.none(), widget=TextInput) But I still get ModelChoiceField validation errors on validate: 'Select a valid choice. That choice is not one of the available

Figured it out - you have to populate both fs._errors _and_ loop through each form in the formset and populate its _errors attribute, as well. On Jun 22, 2:50 pm, snfctech <tschm...@sacfoodcoop.com> wrote: > Hi, Michal. > > I tried that, but the errors don't get rendered for some r

Hi, Kevin. Thanks for your reply. I actually don't want to show the entered values - I basically want the original form with values prior to the user submitting the form - but with the validation errors that prompt them to enter new values in the proper fields. I have already overridden the

Re: how to display form data with original values after validation failure?

Thanks for your reply, Shawn. I'll think about that - but I think I would prefer to use more boiler- plate Django form behavior and just get a formset with errors returned to my template in the full-page response. On Jun 21, 5:44 pm, Shawn Milochik wrote: > One good way is

how to display form data with original values after validation failure?

In the case of editing a form, I want to display the original value of a field prior to validation failure, as well as the validation errors. This doesn't seem to work: if fs.is_valid(): fs.save() else: # return original data - not default

I thought this should be obvious but am having a hard time finding it in the docs. There are a couple snippets that suggest using a custom currency filter: http://www.djangosnippets.org/snippets/552/ http://djangosnippets.org/snippets/1825/ But both use locale.setlocale, which is apparently not

how to display a property in a ModelFormSet?

I'm using a ModelFormSet to display and edit multiple records. Some of those records have related attributes that I want to display, but not edit. E.g. lineitem.quantity [editable] lineitem.product.description [not editable] So I thought I would add a property to my LineItem class in order to

how to implement a data grid? (or populate inlineformset with initial data)

I want to display a list of records that have some editable fields and some readonly fields, as well as asynchronously add new records to the list. I thought the way to start would be with an InlineFormSet - but I can't figure out how to populate my formset with initial data. E.g.
