Load data into ModelForm fields in edit mode before it rendered
To provide the initial data for the field use the initial parameter: form = MyForm(instance=my_obj, initial={'custom_field': 'Test'}) Or, if you want to do it in the __init__ constructor: def __init__(self, *args, **kwargs): kwargs['initial'] = kwargs.get('initial', {}) kwargs['initial']['custom_field'] = 'Test' super(MyForm, self).__init__(*args, **kwargs) ...
Model Fomset and deletion
You can iterate over the formset.deleted_forms: for form in formset.deleted_forms: if form.instance.pk: form.instance.delete() As alternative you can check for DELETE key in the cleaned_data: for job_form in formset: if job_form.is_valid(): if job_form.cleaned_data.get('DELETE') and job_form.instance.pk: job_form.instance.delete() else: instance = job_form.save(commit=False) instance.account = account instance.save() ...

django update view with unique field
You've explicitly popped the instance value from the kwargs dict when the form is instantiated, so the superclass doesn't know that you have an existing instance. Don't do that. In fact, you don't need any of that __init__ method at all. Displaying initial data from an instance is what ModelForms...

Django 1.7 modelform_factory form is always invalid with factory_boy created model
python,django,modelform,factory-boy
This has nothing to do with factory_boy. Forms are always invalid if they don't have any data, which yours doesn't. The instance parameter is used to populate the form's initial data for display, and to determine the object ID for updating, but it isn't used to set that data on...

How to save Django ModelFormSet?
python,django,modelform,formset
As I said in the comment, it doesn't make sense to pass a queryset of Employees to the instantiation of the Salary formset. I think given you're trying to keep these two models completely separate for whatever reason, and you want to create new Salary instances each time, you would...

Django form fields will not display
django,forms,modelform,django-context
The problem is in views.py. In the line: return render(request, "tictactoe/game_do_move.html", {'game': game}) the portion {'game': game} is the context. For any GET request (like rendering a blank form) you aren't rendering the form context variable. Change that line to: return render(request, "tictactoe/game_do_move.html", context) and it should work. You added...
Django: how to write code for modelform of user registration
django,validation,registration,modelform
You don't catch that error. Django does it for you: when you call form.is_valid(), it calls each of the clean_field methods and catches any ValidationError exceptions, putting them into the form.errors attribute. So, what you have is already fine. Except for the major, huge, absolutely vital issue that you should...
