djblets.configforms.forms¶

Base support for configuration forms.

class ConfigPageForm(page, request, user, *args, **kwargs)[source]¶

Base class for a form on a ConfigPage.

Consumers can subclass ConfigPageForm and register it on a djblets.configforms.pages.ConfigPage. It will be shown whenever the user navigates to that page.

A form will generally be shown as a box with a title and a save button, though this is customizable.

A standard form presents fields that can be filled out and posted. More advanced forms can supply their own template or even their own JavaScript models, views, and CSS.

This must be unique across all ConfigPages at a given URL.

form_title = None[source]¶

The displayed title for the form.

save_label = 'Save'[source]¶

The label for the save button.

This can be set to None to disable the button.

template_name = 'configforms/config_page_form.html'[source]¶

The template used to render the form.
