class OGRGeometry(geom_input, srs=None) This object is a wrapper for the OGR Geometry class. These objects are instantiated directly from the given geom_input parameter, which may be a string containing WKT, HEX, GeoJSON, a buffer containing WKB data, or an OGRGeomType object. These objects are also returned from the Feature.geom attribute, when reading vector data from Layer (which is in turn a part of a DataSource). classmethod from_bbox(bbox) Constructs a Polygon from the given bound

format_output(rendered_widgets) [source] Given a list of rendered widgets (as strings), returns a Unicode string representing the HTML for the whole lot. This hook allows you to format the HTML design of the widgets any way you’d like.

This widget is intended to be used with a DateField rather than a MultiValueField, thus we have implemented value_from_datadict():

view_name The name of the view that matches the URL, including the namespace if there is one.

Field.many_to_one Boolean flag that is True if the field has a many-to-one relation, such as a ForeignKey; False otherwise.

password_reset_done(request, template_name='registration/password_reset_done.html', current_app=None, extra_context=None) The page shown after a user has been emailed a link to reset their password. This view is called by default if the password_reset() view doesn’t have an explicit post_reset_redirect URL set. URL name: password_reset_done Note If the email address provided does not exist in the system, the user is inactive, or has an unusable password, the user will still be redirected to
