    a form field.

    ``localized_fields`` is a list of names of fields which should be localized.

    ``labels`` is a dictionary of model field names mapped to a label.

    ``help_texts`` is a dictionary of model field names mapped to a help text.

    ``error_messages`` is a dictionary of model field names mapped to a
    dictionary of error messages.

    ``field_classes`` is a dictionary of model field names mapped to a form
    field class.

    ``apply_limit_choices_to`` is a boolean indicating if limit_choices_to

    Return a ModelForm containing form fields for the given model. You can
    optionally pass a `form` argument to use as a starting point for
    constructing the ModelForm.

    ``fields`` is an optional list of field names. If provided, include only
    the named fields in the returned fields. If omitted or '__all__', use all
    fields.

    ``exclude`` is an optional list of field names. If provided, exclude the
    named fields from the returned fields, even if they are listed in the
    ``fields`` argument.

    ``widgets`` is a dictionary of model field names mapped to a widget.

    ``localized_fields`` is a list of names of fields which should be localized.

    ``formfield_callback`` is a callable that takes a model field and returns
    a form field.

    ``labels`` is a dictionary of model field names mapped to a label.

    ``help_texts`` is a dictionary of model field names mapped to a help text.

    ``error_messages`` is a dictionary of model field names mapped to a
    dictionary of error messages.

    ``field_classes`` is a dictionary of model field names mapped to a form
    field class.
