Readonly text field in Flask-Admin ModelView

Question

How can I make a field on a ModelView readonly?

class MyModelView(BaseModelView):
    column_list = ('name', 'last_name', 'email')

Answer 1

If you're talking about Flask-Admin with SQLAlchemy Models, and you're declaring a view by inheriting from sqlamodel.ModelView, you can just add this to your class definition:

class MyModelView(BaseModelView):
    column_list = ('name', 'last_name', 'email')
    form_widget_args = {
        'email':{
            'disabled':True
        }
    }

I don't have enough reputation to comment on @thkang's answer, which is very close to what worked for me. The disabled attribute excludes the field from the POST data, but using readonly had the desired effect.

from wtforms.fields import TextField

class ReadonlyTextField(TextField):
  def __call__(self, *args, **kwargs):
    kwargs.setdefault('readonly', True)
    return super(ReadonlyTextField, self).__call__(*args, **kwargs)

Answer 3

I got weird errors when I tried to use disabled for text fields, so I used readonly instead:

class MyModelView(BaseModelView):
    column_list = ('name', 'last_name', 'email')
    form_widget_args = {
        'email':{
            'readonly':True
        }
    }

Answer 4

try this:

class DisabledTextField(TextField):
  def __call__(self, *args, **kwargs):
    kwargs.setdefault('disabled', True)
    return super(DisabledTextField, self).__call__(*args, **kwargs)

When you are rendering the field in your Jinja template, just pass in disabled=true if WTForms doesn't recognise the kwarg, it just passes it to be an attribute to the html element.

<form>
{{ form.example(disabled=True) }}
</form>
