Django Models

I’ve been working on a small Django app recently, and started by cleaning up its model definitions. Here’s a quick (but not exhaustive) list of useful configuration options:

Model Meta Options

• db_table = "string"
• managed = False (whether SQL is generated by the manage.py app)
• ordering = ['column1', '-column2'] (NB admin app only uses the first)
• order_with_respect_to = 'fk_field'
• unique_together = (('column1', 'column2'), )
• verbose_name = "String"
• verbose_name_plural = "String"
• abstract = True

Common Field Options

• null = True
• blank = True
• choices = (('db_val', 'displayed_val'), )
• db_column = "string"
• db_index = True
• default = "string"
• editable = False
• primary_key = True
• unique = True
• verbose_name = "String"

Field Types and Options

• AutoField
• BooleanField
• CharField (max_length=integer)
• DateField|DateTimeField(auto_now_add=True)
• IPAddressField
• PositiveIntegerField
• TextField
• ForeignKey(Class, to_field='related_field')
• ManyToManyField(Class, to_field='related_field')
