FileField.upload_to This attribute provides a way of setting the upload directory and file name, and can be set in two ways. In both cases, the value is passed to the Storage.save() method. If you specify a string value, it may contain strftime() formatting, which will be replaced by the date/time of the file upload (so that uploaded files don’t fill up the given directory). For example: class MyModel(models.Model): # file will be uploaded to MEDIA_ROOT/uploads upload = models.FileFi

class TruncMonth(expression, output_field=None, tzinfo=None, **extra) [source] kind = 'month' These are logically equivalent to Trunc('date_field', kind). They truncate all parts of the date up to kind which allows grouping or filtering dates with less precision. expression can have an output_field of either DateField or DateTimeField. Since DateFields don’t have a time component, only Trunc subclasses that deal with date-parts can be used with DateField: >>> from datetime impo

num_fields Returns the number of fields in the layer, i.e the number of fields of data associated with each feature in the layer: >>> layer.num_fields 4
