How can I display different form fields in a class-based view dependin

Question

How can I display different form fields in a class-based view depending upon whether or not the user matches certain criteria??

Rajanikant Hawaldar · Answer

You could use the simple get(), guess the same logic is needed for both get and post.

You can handle this situation in several ways. 1. You can show/hide controls UI based on criteria. 2. Handle in controller action - create seperate view models and return to UI based on criteria in controller itself. Regards Rijwan

Oh my god I finally fixed it. Thanks for your help guys Might not be the most optimal way to do it, but it works and I'm happy about it. I used the dispatch method to solve it.

Rajanikant Hawaldar · Answer

please use Syntax Highligher Code to post code, you are unpacking not self argument, but rather the returning value of its (self's) method get_form_kwargs

Rajanikant Hawaldar · Answer

that's why u have to study Python before Django

Rajanikant Hawaldar · Answer

as i already said you can choose forms dynamicly

Rajanikant Hawaldar · Answer

maybe it is place for strategy pattern so you define a few forms and then depending on situation pick one you need.

So this is how I solved my problem This could have also been solved by using the get() method? #Modifying form fields based upon whether the employee.is_ceo or not def dispatch(self, request, *args, **kwargs): if self.request.user.employee.is_ceo: self.fields = ['first_name', 'last_name', 'assignee', 'number', 'email', 'notes'] else: self.fields = ['first_name', 'last_name', 'number', 'email', 'notes'] return super().dispatch(request, *args, **kwargs)

Rajanikant Hawaldar · Answer

you are not, you are just a beginner and it is not a problem at all you can learn and post here if you dont know

Vijay · Answer

Probably, but I am an actual idiot. I have avoided class-based views this entire time because I don't understand them. Don't even know how to use get()

Vijay · Answer

In def get_form(): return form_class(**self.get_form_kwargs()) I know I am rubbish at Django (and Python!), but I'm just trying to brute force my way through this project. So if I ever get stuck again, I can just look back at my solutions. But after this project, I want to go back to Python and learn more.

Rajanikant Hawaldar · Answer

Where did you get that?

Vijay · Answer

I did, But in my courses I never came across **self.

Vijay · Answer

Thank you! I'll give it a read. Ok, I'm just bad at Python ??. I'll figure it out.

Vijay · Answer

Right, thanks once again both for that. I'll look into it. I have no idea how to actually perform the logic required to help choose which form to use in a class-based view, though:(

Vijay · Answer

OK thank you
