Django: How to access the display value of a ChoiceField in template given the actual value and the choices?

Question

I have a ChoiceField in a bound form, whose choices are:

[('all', 'All users'), ('group', 'Selected groups'), ('none', 'None')]

In the template, I have no problem accessing its bound value (the actual value to be stored; the first element of each tuple) and the choices. With these pieces of info in hands, I know I should be able to access the display values, or the second element of each tuple. But how can I do that in the template? Thanks.

Solution 1

I doubt that it can be done without custom template tag or filter. Custom template filter could look:

@register.filter
def selected_choice(form, field_name):
    return dict(form.fields[field_name].choices)[form.data[field_name]]

Solution 2

Use the get_FOO_display property.

** Edit **

Oups! Quick editing this answer, after reading the comments below.

bound_form['field'].value()

Should work according to this changeset

This is a Model field property but ChoiceField is a Form field, so this is not a viable solution.

Indeed, someone posted the same answer earlier and he removed it.

I'll leave this problem open for another day for digging up other solutions, if any.

Thanks. After hours of research for a solution to the question, I think custom template tag is my best bet.

Your answer applies to Model fields but the question is regarding Form field, so this is not a solution.

Not to mention, the same answer was already provided by Thibault J a while back then and I responded with the same.

I used: return form.fields[field_name].queryset.get(pk=form[field_name].val‌​ue()) The form variable was called while iterating over a formset initialized with queryset=, and its self.data was returning {}. This solution, from the Django IRC logs, solved the problem.

To avoid many database hits, I used: return dict(form.fields[field_name].choices).get(form.initial.get(f‌​ield_name, None), None)
