Facing similar problem, I’ve come to conclusion that it’s not possible. Though having multiple forms per page itself turned out to be a design mistake, presenting all sorts of troubles. E.g., user fills two forms, clicks submit on one of them and loses data from the other. Workaround requires complicated controller that needs to be … Read more
http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#the-save-method When using commit=False, you have to call save_m2m() m2m relationships require the parent object to be saved first, which you are not doing by using commit=False
You can declare an attribute on your ModelForm class, called formfield_callback. This should be a function which takes a Django model Field instance as an argument, and returns a form Field instance to represent it in the form. Then all you have to do is look to see if the model field passed in is … Read more
Making a template tag might work? Something like field.field.widget|widget_type Edit from Oli: Good point! I just wrote a filter: from django import template register = template.Library() @register.filter(‘klass’) def klass(ob): return ob.__class__.__name__ And now {{ object|klass }} renders correctly. Now I’ve just got to figure out how to use that inside a template’s if statement. Edit … Read more
To make a field in a ModelField a hidden field, use a HiddenInput widget. The ModelForm uses a sensible default widget for all the fields, you just need to override it when the object is constructed. class TagStatusForm(forms.ModelForm): class Meta: model = TagStatus widgets = {‘tag’: forms.HiddenInput()}
I’m not sure, if this is what you want, but… Obviously you cannot set initial data for a file input (this would imply that you send a file to the user). Django has a ClearableFileInput widget though, and this widget pretends to show initial data: it displays a link to the uploaded file if the … Read more
Django < 2.0 Answer: Use Django’s Request object (which you have access to) to retrieve the request.path_info, then retrieve the PK from the args in the resolve match. Example: from django.contrib import admin from django.core.urlresolvers import resolve from app.models import YourParentModel, YourInlineModel class YourInlineModelInline(admin.StackedInline): model = YourInlineModel def get_parent_object_from_request(self, request): “”” Returns the parent object … Read more
Update: This answer is from 2011. CSRF is easy today. These days you should be using the render shortcut function return render(request, ‘template.html’) which uses RequestContext automatically so the advice below is outdated by 8 years. Use render https://docs.djangoproject.com/en/2.2/topics/http/shortcuts/ Add CSRF middleware https://docs.djangoproject.com/en/2.2/ref/csrf/ Use the {% csrf_token %} template tag Confirm you see the CSRF … Read more
Use the prefix kwarg You can declare your form as: form = MyFormClass(prefix=’some_prefix’) and then, as long as the prefix is the same, process data as: form = MyFormClass(request.POST, prefix=’some_prefix’) Django will handle the rest. This way you can have as many forms of the same type as you want on the page
You can create a custom widget: from django import forms class DateInput(forms.DateInput): input_type=”date” class MyModelForm(forms.ModelForm): class Meta: model = MyModel fields=”__all__” widgets = { ‘my_date’: DateInput() } There’s no need to subclass DateInput. class MyModelForm(forms.ModelForm): class Meta: model = MyModel fields=”__all__” widgets = { ‘my_date’: forms.DateInput(attrs={‘type’: ‘date’}) }
