GEOSGeometry.unary_union New in Django 1.10. Computes the union of all the elements of this geometry. The result obeys the following contract: Unioning a set of LineStrings has the effect of fully noding and dissolving the linework. Unioning a set of Polygons will always return a Polygon or MultiPolygon geometry (unlike GEOSGeometry.union(), which may return geometries of lower dimension if a topology collapse occurs).

name Required. 80 characters or fewer. Any characters are permitted. Example: 'Awesome Users'.

linear_units Returns the value of the linear units.

BaseCommand.get_version() [source] Returns the Django version, which should be correct for all built-in Django commands. User-supplied commands can override this method to return their own version.

class ClearableFileInput [source] File upload input: <input type='file' ...>, with an additional checkbox input to clear the field’s value, if the field is not required and has initial data.

Form.has_changed() Use the has_changed() method on your Form when you need to check if the form data has been changed from the initial data. >>> data = {'subject': 'hello', ... 'message': 'Hi there', ... 'sender': 'foo@example.com', ... 'cc_myself': True} >>> f = ContactForm(data, initial=data) >>> f.has_changed() False When the form is submitted, we reconstruct it and provide the original data so that the comparison can be done: >>&g

BoundField.form The Form instance this BoundField is bound to.

class DateTimeInput [source] Date/time input as a simple text box: <input type='text' ...> Takes same arguments as TextInput, with one more optional argument: format The format in which this field’s initial value will be displayed. If no format argument is provided, the default format is the first format found in DATETIME_INPUT_FORMATS and respects Format localization. By default, the microseconds part of the time value is always set to 0. If microseconds are required, use a subc

widgets An iterable containing the widgets needed. And one required method:
