- Content Access Module
- -----------------------
- by Wolfgang Ziegler, nuppla@zites.net
- Yet another node access module.
- This module allows you to manage permissions for content types by role. It allows you to specifiy
- custom view, view own, edit, edit own, delete and delete own permissions for each content type.
- Optionally you can enable per content access settings, so you can customize the access for each
- content node.
- In particular
- * it comes with sensible defaults, so you need not configure anything and everything stays working
- * it is as flexible as you want. It can work with per content type settings, per content node settings
- as well as with flexible Access Control Lists (with the help of the ACL module).
- * it trys to reuse existing functionality instead of reimplementing it. So one can install the ACL
- module and set per user access control settings per content node.
- Furthermore the module provides conditions and actions for the rules module, which allows one
- to configure even rule-based access permissions.
- * it optimizes the written content node grants, so that only the really necessary grants are written.
- This is important for the performance of your site.
- * it takes access control as important as it is. E.g. the module has a bunch of simpletests to ensure
- everything is working right.
- * it respects and makes use of drupal's built in permissions as far as possible. Which means the
- access control tab provided by this module takes them into account and provides you a good overview
- about the really applied access control settings. [1]
- So the module is simple to use, but can be configured to provide really fine-grained permissions!
- Installation
- ------------
- * Copy the content access module's directory to your modules directory and activate the module.
- * Optionally download and install the ACL module too.
- * Edit a content type at admin/content/types. There will be a new tab "Access Control".
- ACL Module
- -----------
- You can find the ACL module at http://drupal.org/project/acl. To make use of Access Control Lists
- you'll need to enable per content node access control settings for a content type. At the access
- control tab of such a content node you are able to grant view, edit or delete permission for specific
- users.
- Running multiple node access modules on a site (Advanced!)
- -----------------------------------------------------------
- A drupal node access module can only grant access to content nodes, but not deny it. So if you
- are using multiple node access modules, access will be granted to a node as soon as one of the
- module grants access to it.
- However you can influence the behaviour by changing the priority of the content access module as
- drupal applies *only* the grants with the highest priority. So if content access has the highest
- priority *alone*, only its grants will be applied.
- By default node access modules use priority 0.
- Footnotes
- ----------
- [1] Note that this overview can't take other modules into account, which might also alter node access.
- If you have multiple modules installed that alter node access, read the paragraph about "Running
- multiple node access modules on a site".
