|
|
* Remove all links project_id = -1 (added links to an issue which hasn't been created)
|
|
* Report all documents without a corresponding file in the file system (dry_run only)
|
|
|
|
Available options:
|
|
*dry_run - No physical deletion but to list of all unused files only
|
|
|
|

|
|
rake redmine:dmsf_maintenance RAILS_ENV="production"
|
|
rake redmine:dmsf_maintenance dry_run=1 RAILS_ENV="production"
