Dictionary of choices based in models
Sometimes we need to build a ChoiceField from data in a Model or more than just one model via fk's but the ModelChoiceField is not *that* flexible. So, in order to obtain a list of tuples with pk and a descriptive text for the choices parameter of the ChoiceField use this little function.

Rendering radio-buttons with icons instead of labels
I was looking for a way to save screen real estate, by using icons instead of labels for my list of choices, which in addition should be displayed as horizontal radio buttons. For example, I wanted to use thumbs_up.gif instead of "approve". I found a HorizontalRadioRenderer here: [https://wikis.utexas.edu/display/~bm6432/Django-Modifying+RadioSelect+Widget+to+have+horizontal+buttons](https://wikis.utexas.edu/display/~bm6432/Django-Modifying+RadioSelect+Widget+to+have+horizontal+buttons) Thanks to Barry McClendon for this snippet! At first, I tried to achieve display of icons instead of labels by modifying the render method, but after a while I gave up on that and decided to just use the choices tuple. This doesn't work too well with a select box (no icons, no text), but in combination with a radio widget it looks quite nice. If you mark the strings for translation, you can also easily change icons, alt and title for each language.

Modify fields created by form_for_model
Using newforms you can create forms from existing models easily and automatically with either `form_for_model(class)` or `form_for_instance(instance)`. Usually the automagically generated form fields are sufficient; however, sometimes you need to restrict selections in a choice field. You can also set the default selection when instantiating the form. In this example, if `acct` is not contained in the 'account' field choices, the selection defaults to the first entry. This example is probably not good practice when using `form_for_instance` because the existing value 'selection' of the choice field is lost and must be reset manually (see above).

ChoiceField with widget in choice
This code creates a widget that we used to generate a list of radiobuttons as follows: * Radio button 1 --Widget__1 * Radio button 2 --Widget__2 * Radio button 3 --Widget__3 How to use it is: `ImagenForm class (forms.ModelForm): widget1 = forms.BooleanField () widget2 = forms.TextInput widget3 = forms.ModelChoiceField (queryset = Modelo.objects.all ()) widget4 = forms.FileInput optConListas = ChoiceWithOtherField (choices = [(2, 'widget1' widget1), (3, 'widget2' widget3.widget), (4, "widget2" widget2), (5, 'widget4' widget4)])`
