< < | Referring TopicsReferring topics are found using the the %SEARCH% variable, see the templatesearchrenameview.tmpl . First, matching topics in the current Web are listed - matches are to topic. Next, all Webs (including the current one) are listed that match web.topic. Because %SEARCH% is used, Webs marked in WebPreferences as NOSEARCHALL will not show up in the search for refernces to the topic being changed.
Changed references are kept are as short as possible, ex: topic is used in preference to web.topic. | |||||||

< < | Rename/move in is fairly complicated due to the dynamic generation of links. Ideally, it would be possible to run the required part of rendering in a way that would allow identification of the text to be changed. Unfortunately, these hooks don't exist in TWiki at present. Instead, %SEARCH% is used with a special template to show the text to be changed, and the selected topics are then altered. One drawback is that search can show matches that will not be updated because of case differences. Other mismatches to actual rendered output are also possible as the approaches are so different. | |||||||

Effect of User Access SettingsUser permissions affect the Rename function in various ways. To rename a topic, you need bothALLOWTOPICCHANGE and ALLOWTOPICRENAME permission for that topic. To alter referring topics, you need change permission. See TWikiAccessControl for information on setting up access permissions.
Special ConsiderationsConsider carefully whether to make browser-based Rename/Move/Delete widely available, or to restrict it to an administrator/moderator group. Allowing all users to easily manipulate topics can be extremely useful in refactoring a busy web or site. However, there are at least two significant potential drawbacks to take into account:
