ignore fields on update view-CodePudding

I have a very large form that I have an update view for. The issue is when the users submits an update it says some fields are required such as author and post date. I don't want users to change these fields. The fields are manually rendered

How can I ignore these fields in the update view.

I have tried to set the requirements to false

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    self.fields['author'].required = False
    self.fields['date_posted'].required = False

But this throws a null value in column "author" of relation "blog_post" violates not-null constraint

Alot of posts said to add null=True but these fields cannot be null

view:

class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = Post
    form_class = PostFormUpdate
   
    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)

    def test_func(self):
        post = self.get_object()
        if self.request.user.id == post.author_id:
            return True
        return False

form:

class PostFormUpdate(ModelForm):
    class Meta:
        model = Post
        fields = '__all__'

CodePudding user response：

you can set blank=True either in model class which will be implemented on all http methods or using the above technique you used

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    self.fields['author'].blank = True
    self.fields['date_posted'].blank = True

blank=True means you are not requiring any values from forms for those fields...

CodePudding user response：

This makes it so the user cannot change the form field but it is still displayed

widgets = {
   'date_posted': forms.TextInput(attrs={'readonly':'readonly'}), }


def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    self.fields['date_posted'].required = False
