Topic Create Plugin
This Plugin allows you to automatically create new topics or attach files at topic save time. This is typically used by TWiki applications to create a set of topics based on different templates.
TOPICCREATE - Automatically Create a Set of TWiki Topics
- The
%TOPICCREATE{}%
TWikiVariable is useful for creating topics based on templates.
- Example scenario: You have a notebook application where users can create new notebooks based on a notebook template topic. Each time a user creates a new notebook you would like to create a set of children topics, each based on a different template.
- Syntax:
%TOPICCREATE{ <attributes> }%
- Attributes recognized:
Attribute | Meaning | Valid input | Default |
template="" | Name of TWiki topic to be used as template | Any valid TWiki topic | (required) |
topic="" | Name of new TWiki topic to create | Any valid WikiWord | (required) |
parent="" | Name of parent topic | Any valid WikiWord | (parent of template topic) |
disable="" | Name of the template topic containing this use of TOPICCREATE | Any valid topic name (WikiWord) | recommended |
parameters="" | List of parameters to pass to a child topic to initialize any urlparams. | Following syntax: <parameter-name>=<parameter-value> followed by any number of parameter name, value pairs separated by & or ; | No Parameters |
- The action to create the TWiki topic will not occur until one hits the
Save Changes
button in preview.
- The
%TOPICCREATE{}%
variable will be removed upon saving of the topic.
- Any attachments that are in the
template
will also be copied over to the new topic.
-
%TOPICCREATE%
is recursive
- Write
%TOPICCREATE{ template="MyTemplate" topic="%TOPIC%MyNewTopicName" parameters="MyParameterName=MyParameterValue&Hello=Goodbye" }%
to create a twiki topic based on another topic MyTemplate
with the name %TOPIC%MyNewTopicName
. Any %URLPARAM{}%
with the name MyParameterName
and Hello
present in MyTemplate
will be replaced with MyParameterValue
and Goodbye
.
- To prevent the action from happening in your template topic you should either include the
disable
argument, or escape it: %TOPICCRE%NOP%ATE{...}%
. The %NOP%
gets removed when a topic gets instantiated based on a template.
TOPICATTACH - Automatically Copy Attachments to a Topic
- Example scenario: You have a template topic and would like to attach a file whose's content or name is determined by URL parameters at topic creation time. This is usually done for a topic that was just created via TOPICCREATE as described above.
- Syntax:
%TOPICATTACH{ <attributes> }%
- Attributes recognized:
Attribute | Meaning | Valid input | Default |
fromtopic="" | Topic (or Web.Topic) that contains the attachment | Any valid TWiki topic | (required) |
fromfile="" | The attachment to copy from | Any attached file from fromtopic | (required) |
disable="" | Name of the template topic containing this use of TOPICATTACH | Any valid topic name (WikiWord) | (required) |
comment="" | Comment to appear for the attachment within this topic, replacing the comment that was in the fromtopic | a one line string | {omit parameter if no change desired} |
- Write
%TOPICATTACH{ fromtopic="SourceTopic" fromfile="Sample.jpg" name="Snoopy.jpg" disable="..."}%
to attach Sample.jpg
from topic SourceTopic
as Snoopy.jpg
.
- The parameter value comment is used to change the comment (description) that shows for the topic in the table of attachments.
- The "hidden" attribute of the topic is removed: the attachment can be hidden in the
fromtopic
if desired.
- The
fromtopic
can specify a different web if desired. For example TWiki.SomeTemplate
would be valid as a fromtopic
.
- To prevent the action from happening in your template topic you must provide the
disable
parameter with the topic name containing the %TOPICATTACH%
.
Known issues & limitations
- The
TOPICATTACH
must be in the 'top level' topic being saved by a TOPICCREATE
. It can not be in a recursive/subordinate topic invoked by the TOPICCREATE.
