I use Django 5.1.2

In order to clarify what my users need to do when my app serves them a form, I’ve added a dict to my forms called ‘contents’. It contains a bunch of instructions for the template form.html:

class MyForm(forms.Form):
    contents = {
        'icon' : 'img/some-icon.png',
        'title' : 'Description of form',
        'message' : 'Some instruction for user',
        'value' : 'text-label-of-the button',
    }
    class Meta:
         fields = ('',)

Then in the view myview the form.contents are updated according to what the view does:

def myview(request):
    if request.method == 'GET':
        form = MyForm()
        form.contents.update({ 
            'icon' : 'img/wrong_red.png',
            'title' : 'You did it wrong',
            'color' : 'red',
            'message' : 'Something user did wrong',
            'value' : 'Cancel',
        })
        context = {'form' : form}
        return render(request, 'form.html', context)

I run into the problem that the updated content for color persist throughout multiple requests from users. I would expect that update to a value in a class instance wouldn’t persist. In my memory this used to be the case. As a work-around I could make a unique form class for each view, but this would result in a lot of repetitive code. What is the best fix for this issue?
