A TextField which stores its value on the model instance as a python object and stores its value in the database as JSON. Validated with json_validator().
Stores a selection of multiple items with unique slugs in the form of a comma-separated list. Also knows how to correctly handle RegistryIterators passed in as choices.
A TextField which is validated with a TemplateValidator. allow, disallow, and secure will be passed into the validator’s construction.
AttributeProxyFields can be assigned as fields on a subclass of philo.models.base.Entity. They act like any other model fields, but instead of saving their data to the model’s table, they save it to Attributes related to a model instance. Additionally, a new Attribute will be created for an instance if and only if the field’s value has been set. This is relevant i.e. for PassthroughAttributeMappers and TreeAttributeMappers, where even an Attribute with a value of None will prevent a passthrough.
class Thing(Entity): numbers = models.PositiveIntegerField() improvised = JSONAttribute(models.BooleanField)
|Parameters:||attribute_key – The key of the attribute that will be used to store this field’s value, if it is different than the field’s name.|
The remaining parameters have the same meaning as for ordinary model fields.
Returns a form field capable of accepting values for the AttributeProxyField.
