lino.mixins¶

This package contains model mixins, some of which are heavily used by applications and the Lino Extensions Library. But none of them is mandatory.

`duplicable`	Defines the model mixin `Duplicable`.
`dupable`	Defines the `Dupable` model mixin and related functionality to assist users in finding unwanted duplicate database records.
`sequenced`	Defines the model mixins `Sequenced` and `Hierarchical`.
`human`	See test cases and examples in The Human mixin.
`periods`	Defines classes related to date ranges.
`polymorphic`	Defines the `Polymorphic` model mixin.
`ref`	Defines the `Referrable` model mixin.
`registrable`	This defines the `Registable` model mixin.

(This module's source code is available here.)

Classes

`Contactable`(args, *kwargs)	Mixin for models that represent somebody who can be contacted by email.
`Created`(args, *kwargs)	Adds a timestamp field which holds the creation time of every individual database object.
`CreatedModified`(args, *kwargs)	Adds two timestamp fields created and modified.
`Modified`(args, *kwargs)	Adds a a timestamp field which holds the last modification time of every individual database object.
`Phonable`(args, *kwargs)	Mixin for models that represent somebody who can be contacted by phone.
`ProjectRelated`(args, *kwargs)	Mixin for models that are related to a "project", i.e. to an object of the type given by your lino.core.site.Site.project_model.
`Story`(args, *kwargs)

class lino.mixins.Contactable(*args, **kwargs)¶

Mixin for models that represent somebody who can be contacted by email.

class lino.mixins.Phonable(*args, **kwargs)¶

Mixin for models that represent somebody who can be contacted by phone.

class lino.mixins.Modified(*args, **kwargs)¶

Adds a a timestamp field which holds the last modification time of every individual database object.

auto_touch = True¶

Whether to touch objects automatically when saving them.

If you set this to False, modified is updated only when you explicitly call touch().

class lino.mixins.Created(*args, **kwargs)¶

Adds a timestamp field which holds the creation time of every individual database object.

created¶

The time when this object was created.

Does nut use Django's auto_now and auto_now_add features because their deserialization would be problematic.

class lino.mixins.CreatedModified(*args, **kwargs)¶

Adds two timestamp fields created and modified.

class lino.mixins.ProjectRelated(*args, **kwargs)¶

Mixin for models that are related to a "project", i.e. to an object of the type given by your lino.core.site.Site.project_model.

This adds a field named project and related methods.

project¶

Pointer to the project to which this object is related.

If the application's project_model is empty, the project field will be a DummyField.

update_owned_instance(controllable)¶: When a project-related object controls another project-related object, then the controlled automatically inherits the project of its controller.
