Widgets have an attrs keyword argument that take a dict which can define attributes for the input element that it renders.

Take the following example: class MyForm(forms.Form): error_css_class=”error” required_css_class=”required” my_field = forms.CharField(max_length=10, widget=forms.TextInput(attrs={‘id’: ‘my_field’, ‘class’: ‘my_class’})) This works on any … Read more

Django templates: verbose version of a choice

by

In Django templates you can use the “get_FOO_display()” method, that will return the readable alias for the field, where ‘FOO’ is the name of the field. Note: in case the standard FormPreview templates are not using it, then you can always provide your own templates for that form, which will contain something like {{ form.get_meal_display … Read more

Django: adding an “Add new” button for a ForeignKey in a ModelForm

I just wrote a filter: from django import template register = template.Library() @register.filter(‘klass’) def klass(ob): return ob.__class__.__name__ And now {{ object|klass }} renders correctly. Now I’ve just got to figure out how to use that inside a template’s if statement. Edit … Read more

Customize/remove Django select box blank option

by

Haven’t tested this, but based on reading Django’s code here and here I believe it should work: class ThingForm(forms.ModelForm): class Meta: model = Thing def __init__(self, *args, **kwargs): super(ThingForm, self).__init__(*args, **kwargs) self.fields[‘verb’].empty_label = None EDIT: This is documented, though you wouldn’t necessarily know to look for ModelChoiceField if you’re working with an auto-generated ModelForm. EDIT: … Read more
