How to disable field from View on Django?-CodePudding

I am struggling trying to disable it, but I am using the same form for two different views, and on one view I need to disable or readonly a field, how can I reach this?

I reach this so far on VIEWS.py

obj = ModelUpdate.objects.first()
field_object = ModelUpdate._meta.get_field('myfield')
field_value = getattr(obj, field_object.attname)

I presume you want to re-use a form in two separate views but have one version have a readonly field? If so, you could either have two versions of the form in your forms.py file, if the form code is not particularly long, or you could add some sort of check in the def __init__ of the form to set the field as readonly under a certain condition:

my_field = forms.CharField(widget=forms.TextInput(attrs={'readonly':'readonly'}))

Edit:

If you don't want two separate forms, you could do this:

class MyForm(forms.ModelForm):
   ...

   def __init__(self, my_field_is_read_only=False, *args, **kwargs):
      super(MyForm, self).__init__(*args, **kwargs)

      if my_field_is_read_only:
         self.fields['my_field'].widget.attrs['readonly'] = True

You can use inheritance.

class AbstractForm(forms.Form):
    # General fields

class AllEditableForm(AbstractForm):
    # The field which we will allow to edit
    target_field = forms.XXXXField()
    
class OneFieldReadOnly(AbstractForm):
    # Make the field read only
    target_field = forms.XXXXField(disabled=True)
