copied!<p>As Benjamin (<a href="https://stackoverflow.com/a/2359167/565525">https://stackoverflow.com/a/2359167/565525</a>) nicely explained, additionally to rendering correctly, you need to process field on backend properly. </p> <p>There is an SO <a href="https://stackoverflow.com/questions/324477/in-a-django-form-how-to-make-a-field-readonly-or-disabled-so-that-it-cannot-b?rq=1">question and answers</a> that has many good solutions. But anyway:</p> <p>1) first approach - removing field in save() method, e.g. (not tested ;) ):</p> <pre><code>def save(self, *args, **kwargs): for fname in self.readonly_fields: if fname in self.cleaned_data: del self.cleaned_data[fname] return super(<form-name>, self).save(*args,**kwargs) </code></pre> <p>2) second approach - reset field to initial value in clean method:</p> <pre><code>def clean_<fieldname>(self): return self.initial[<fieldname>] # or getattr(self.instance, <fieldname>) </code></pre> <p>Based on second approach I generalized it like this:</p> <pre><code>from functools import partial class <Form-name>(...): def __init__(self, ...): ... super(<Form-name>, self).__init__(*args, **kwargs) ... for i, (fname, field) in enumerate(self.fields.iteritems()): if fname in self.readonly_fields: field.widget.attrs['readonly'] = "readonly" field.required = False # set clean method to reset value back clean_method_name = "clean_%s" % fname assert clean_method_name not in dir(self) setattr(self, clean_method_name, partial(self._clean_for_readonly_field, fname=fname)) def _clean_for_readonly_field(self, fname): """ will reset value to initial - nothing will be changed needs to be added dynamically - partial, see init_fields """ return self.initial[fname] # or getattr(self.instance, fname) </code></pre>
