The django CMS permissions system is flexible, granular and multi-layered.
Permissions operate in two different modes, depending on the
Simple permissions mode (
CMS_PERMISSION = False): only the standard Django Users and Groups permissions will apply. This is the default.
Page permissions mode (
CMS_PERMISSION = True): as well as standard Django permissions, django CMS provides row-level permissions on pages, allowing you to control the access of users to different sections of a site, and sites within a multi-site project.
Key user permissions#
You can find the permissions you can set for a user or groups in the Django admin, in the Authentication and Authorization section. These apply equally in Simple permissions mode and Page permissions mode.
cms will show the ones that belong to the CMS application. Permissions that a CMS
editor will need are likely to include:
cms | cms plugin
cms | page
cms | placeholder
cms | placeholder reference
cms | static placeholder
cms | placeholder reference
cms | title
Most of these offer the usual add/change/delete options, though there are some exceptions, such as
cms | placeholder | Can use Structure mode.
See Use permissions on Groups, not on Users below on applying permissions to groups rather than users.
Permissions in Page permissions mode#
In Page permissions mode, you also need to give users permission to the right pages and sub-sites.
Global and per-page permissions#
This can be done in two ways, globally or per-page.
Global page permissions apply to all pages (or all pages on a sub-site in a multi-site project). Global page permissions are managed in the admin at django CMS > Pages global permissions.
Per-page permissions apply to a specific page and/or its children and/or its descendants. Per-page permissions are managed via the toolbar (Page > Permissions) when on the page in question, in edit mode.
Your users (unless they are Django superusers) will need at least one of global page permissions or per-page permissions granted to them in order to be able to edit any pages at all.
They will also need appropriate user permissions, otherwise they will have no edit rights to pages.
Page permission options#
Both global page permissions and per-page permissions can be assigned to users or groups of users. They include:
Can change advanced settings
Can change permissions
Even though a user may have Can edit permissions on a page, that doesn’t give them permissions to add or change plugins within that page. In order to be able to add/change/delete plugins on any page, you will need to go through the standard Django permissions to provide users with the actions they can perform, for example:
cms | page | Can publish pageto publish it
cms | cms plugins | Can edit cms pluginto edit plugins on the page
Per-page permissions are controlled by selecting Permissions from the Page menu in the toolbar
when on the page (this options is only available when
CMS_PERMISSION mode is on).
Login required determines whether anonymous visitors will be able to see the page at all.
Menu visibility determines who’ll be able to see the page in navigation menus - everyone, or logged in or anonymous users only.
View restrictions determine which groups and users will be able to see the page when it is published. Adding a view restriction will allow you to set this. Note that this doesn’t apply any restrictions to users who are also editors with appropriate permissions.
Page permissions determine what editors can do to a page (or hierarchy of pages). They are described above in Page permission options.
New admin models#
CMS_PERMISSION is enabled, as well as Pages global permissions you will find two new models available in the CMS admin:
User groups (page)
You will find that the latter two simply reflect the Django Groups and User permissions that already exist in the system, and can be ignored.
For a simple site with only a few users you may not need to be concerned about this, but with thousands of pages belonging to different departments and users with greatly differing levels of authority and expertise, it is important to understand who is able to do what on your site.
Use permissions on Groups, not on Users#
Avoid applying permissions to individual users unless strictly necessary. It’s far better to apply them to Groups, and add Users to Groups. Otherwise, you risk ending up with large numbers of Users with unknown or inappropriate permissions.
Use Groups to build up permissions#
Different users may require different subsets of permissions. For example, you could define a Basic content editor group, who can edit and publish pages and content, but who don’t have permission to create new ones; that permission would be granted to a Lead content editor Group. Another Group could have permissions to use the weblog.
Then, when managing a user, place the user into the appropriate groups.
Two dimensions of permissions#
You can divide your users’ permissions across two dimensions:
what sort of things this user or group of user should be allowed to do (e.g. publish pages, add new plugins, create new users, etc)
which sections of the site the user should be allowed to do them on (the home page, a limited set of departmental pages, etc)
Groups are very useful for managing this. For example, you can create a Europe group for editors who are allowed to edit the Europe page hierarchy or sub-site. The group can then be added to a global or per-page permission.
