Page

Bases: Model

The page class to build a Wiki Each page may have a parent and it's URL is of the form my.site/page/// It has an ID field, but don't use it, since it's only there for DB part, and because compound primary key is awkward! Prefere querying pages with Page.get_page_by_full_name().

Be careful with the _full_name attribute: this field may not be valid until you call save(). It's made for fast query, but don't rely on it when playing with a Page object, use get_full_name() instead!

Bases: View

Protect any child view that would create an object.

Raises:

Ensure the user has permission to edit this view's object.

Raises:

Type	Description
PermissionDenied	if the user cannot edit this view's object.

CanEditPropMixin

Bases: GenericContentPermissionMixinBuilder

Ensure the user has owner permissions on the child view object.

In other word, you can make a view with this view as parent, and it will be retricted to the users that are in the object's owner_group or that pass the obj.can_be_viewed_by test.

Raises:

Type	Description
PermissionDenied	if the user cannot edit this view's object.

Customer

Bases: Model

Customer data of a User.

It adds some basic customers' information, such as the account ID, and is used by other accounting classes as reference to the customer, rather than using User.

can_buy: bool property

Check if whether this customer has the right to purchase any item.

This must be not confused with the Product.can_be_sold_to(user) method as the present method returns an information about a customer whereas the other tells something about the relation between a User (not a Customer, don't mix them) and a Product.
