GEOSGeometry.srid Property that may be used to retrieve or set the SRID associated with the geometry. For example: >>> pnt = Point(5, 23) >>> print(pnt.srid) None >>> pnt.srid = 4326 >>> pnt.srid 4326

day Optional The value for the day, as a string. By default, set to None, which means the day will be determined using other means.

class TodayArchiveView [source] A day archive page showing all objects for today. This is exactly the same as django.views.generic.dates.DayArchiveView, except today’s date is used instead of the year/month/day arguments. Ancestors (MRO) django.views.generic.list.MultipleObjectTemplateResponseMixin django.views.generic.base.TemplateResponseMixin django.views.generic.dates.BaseTodayArchiveView django.views.generic.dates.BaseDayArchiveView django.views.generic.dates.YearMixin django.views.gene

for_concrete_model If False, the field will be able to reference proxy models. Default is True. This mirrors the for_concrete_model argument to get_for_model().

class GeoHash(expression, precision=None, **extra) Availability: PostGIS, SpatiaLite (≥ 4.0, LWGEOM) Accepts a single geographic field or expression and returns a GeoHash representation of the geometry. The precision keyword argument controls the number of characters in the result. Changed in Django 1.10: SpatiaLite support was added.

class LineString x Returns a list of X coordinates in this line: >>> OGRGeometry('LINESTRING (1 2,3 4)').x [1.0, 3.0] y Returns a list of Y coordinates in this line: >>> OGRGeometry('LINESTRING (1 2,3 4)').y [2.0, 4.0] z Returns a list of Z coordinates in this line, or None if the line does not have Z coordinates: >>> OGRGeometry('LINESTRING (1 2 3,4 5 6)').z [3.0, 6.0]

LogEntry.action_flag The type of action logged: ADDITION, CHANGE, DELETION. For example, to get a list of all additions done through the admin: from django.contrib.admin.models import LogEntry, ADDITION LogEntry.objects.filter(action_flag=ADDITION)

authenticate(username=None, password=None, **kwargs) Tries to authenticate username with password by calling User.check_password. If no username is provided, it tries to fetch a username from kwargs using the key CustomUser.USERNAME_FIELD. Returns an authenticated user or None.

ellipsoid Returns a tuple of the ellipsoid parameters for this spatial reference: (semimajor axis, semiminor axis, and inverse flattening).
