# Feature request: wigets attribute for ModelFormMixin class
### Status quo
The `ModelFormMixin` class currently implements the `fields` attribute by
it self and pass it to the `modelform_factory`:
```python
class ModelFormMixin(FormMixin, SingleObjectMixin):
"""Provide a way to show and handle a ModelForm in a request."""
fields = None
def get_form_class(self):
"""Return the form class to use in this view."""
if self.fields is not None and self.form_class:
raise ImproperlyConfigured(
"Specifying both 'fields' and 'form_class' is not
permitted."
)
if self.form_class:
return self.form_class
else:
...
return model_forms.modelform_factory(model, fields=self.fields)
```
On generic `CreateView` for example the field can be configured like:
```python
class MonitoringRunNewView(CreateView):
model = MonitoringRun
fields = ('metadatas', )
...
```
Same can be done in `UpdateView` and so on.
### Enhancement
Provide the possibility to declare widgets for the configured fields also
like:
```python
class ModelFormMixin(FormMixin, SingleObjectMixin):
"""Provide a way to show and handle a ModelForm in a request."""
fields = None
widgets = None
def get_form_class(self):
"""Return the form class to use in this view."""
if self.fields is not None and self.form_class:
raise ImproperlyConfigured(
"Specifying both 'fields' and 'form_class' is not
permitted."
)
if self.form_class:
return self.form_class
else:
...
return model_forms.modelform_factory(model, fields=self.fields,
widgets=self.widgets)
```
```python
class MonitoringRunNewView(CreateView):
model = MonitoringRun
fields = ('metadatas', )
widgets = {'metadatas': forms.HiddenInput()}
...
```
Configuring of `labels`, `help_texts` and `error_messages` could also be
helpfull. For that we also simply need to pass the attributes as in the
example above described.
