[Django]-Read-Only Field in Django Form

In django 1.9 in a Field.disabled attribute available : https://docs.djangoproject.com/en/1.9/ref/forms/fields/#disabled

The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won’t be editable by users. Even if a user tampers with the field’s value submitted to the server, it will be ignored in favor of the value from the form’s initial data.

otherwise

use the widget ‘readonly’ attribute

class PatientForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
       super(PatientForm, self).__init__(*args, **kwargs)
       self.fields['field'].widget.attrs['readonly'] = True

    class Meta:
        model = Patient

In Django 1.9+:

somefield = forms.CharField(disabled=True)

Maybe one of the best way to do it in front side is widget-tweak even more if you use your form in multiple view.

If you don’t want to install extra lib you can simply add field manually and use the django input attribut.
Like this :

<input 
    name="{{ form.fieldname.name }}" 
    type="{{ form.fieldname.widget.input_type }}" 
    readonly="readonly"
    >
</input>

Here is the only way I get it to work in Js:

function myFieldOnChange() {
    var myField= document.getElementById("myFieldID")
    myField.setAttribute('readonly', true)
