The simplest way of displaying a "details" table about any model, is to show a ModelFrom with all fields readonly or (selects) disabled.

Also, the labels are preferably translatable, not just capitalized names of the column tables in your models. So the constructor translates the field labels as well.

from django import forms

class ReadOnlyForm(forms.ModelForm):
    """Base class for making a form readonly."""
    def __init__(self, *args, **kwargs):
        from django.utils.translation import ugettext as _
        from django.forms.widgets import Select
        super(ReadOnlyForm, self).__init__(*args, **kwargs)
        for f in self.fields:
            self.fields[f].label = _(self.fields[f].label)
            if isinstance(self.fields[f].widget, Select):
                self.fields[f].widget.attrs['disabled'] = 'disabled'
            else:
                self.fields[f].widget.attrs['readonly'] = 'readonly'

Thanks, this is very useful. However, the readonly attribute does not work for inputs with type file, so I think that for files, there should be a new Widget, which displays the file.
