This module is used to delete all content and/or users from a site. This is mainly a developer tool, which can come in handy in several cases, listed below.
The usual way to do this is to go to Administer -> Content then select all the nodes and delete them. This works if you have a handful of nodes only. If you have hundreds or thousands of nodes, then it is not a practical solution.
Another option is to directly delete the nodes from the node table in the database. This does not work properly, since there are also comments, and many tables for add on modules that needs to be cleaned.
- This is a test site that the client was using for a period of time, and they must clean it up before starting with real data.
- You are testing something that creates a lot of nodes (e.g. aggregator), and want to do it over and over again.
- You created a site in the past and want to replicate it again, but with new content.
Note that for nodes, comments and all additions to nodes that contributed modules may have added. For users, any additional module data will also be deleted.
Example: drush delete-all article
Drush on Drupal 7 version
Delete all nodes, nodes of a specific content type or users. Examples: drush delete-all article Delect all article nodes. drush delete-all all Delete nodes of all types. drush delete-all --reset Delete nodes of all types, and reset node, revision and comment counters. drush delete-all users Delete users. Options: --reset Reset counter for node, revision and comment tables. --roles pick roles Aliases: da
In order to use this module, install it it and enable it as with any other module. You will then see two new entries, one under Administer -> Content, and the other under Administer -> Users. A confirmation message will be displayed before the actual deletion happens.
When deleting nodes, you can select to delete all nodes, or just delete nodes by type.
There are also two methods for deleting nodes. The "normal" method uses node_delete, and is the preferred way of doing things. But if your site has hundreds or thousands of nodes, node_delete can take quite long. The "quick" method is for these cases when there are thousands of nodes. It deletes everything using SQL by joining the tables. Since it deletes thousands of nodes at a time in a single sql statement and bypasses lots of php and the module's hook_delete, it's much quicker. But it's not as safe a way of deleting as using the "normal" method.
A new 7.x-dev release is available which works for Drupal 7 and incorporates the ability to use "drush delete-all " for deleting nodes via the command line. I (nowarninglabel) will provide some support for the D7 version of this module.
