@ -19,9 +19,33 @@ There is a Doxyfile at the root of the project, meaning that if you have Doxygen
generate a complete HTML documentation that will be available in the *./doc/html/* folder.
### Dependencies:
* Django 1.8
* Pillow
See requirements.txt
The development is done with sqlite, but it is advised to set a more robust DBMS for production (Postgresql for example)
### Misc about development
#### Controlling the rights
When you need to protect an object, there are three levels:
* Editing the object properties
* Editing the object various values
* Viewing the object
Now you have many solutions in your model:
* You can define a `is_owned_by(self, user)`, a `can_be_edited_by(self, user)`, and/or a `can_be_viewed_by(self, user)`
method, each returning True is the user passed can edit/view the object, False otherwise.
This allows you to make complex request when the group solution is not powerful enough.
It's useful too when you want to define class-wide permissions, e.g. the club members, that are viewable only for
Subscribers.
* You can add an `owner_group` field, as a ForeignKey to Group. Second is an `edit_groups` field, as a ManyToMany to
Group, and third is a `view_groups`, same as for edit.
Finally, when building a class based view, which is highly advised, you just have to inherit it from CanEditPropMixin,
CanEditMixin, or CanViewMixin, which are located in core.views. Your view will then be protected using either the
appropriate group fields, or the right method to check user permissions.
