Question

I would love to make some pages available with only Edittable access while preventing "full" page editing via the "Edit" link and TWiki edit window.

Can I do anything like this?

If not possible (yet) I'd like to request such an enhancement.

it would be, similarly, nice to be able to use CommentPlugin but disallow Edit

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

Well one way to do this is to create a modification of the skin you are using to remove those features and then do a Set SKIN = on that page. For example that is the way we created a limited feature version of some pages on our wiki. For example:

http://www.gpstk.org/bin/view/Documentation/WebHome

http://www.gpstk.org/bin/view/Documentation/SystemRequirements

That is one way.

Another option is to modify the skin to conditionally show the edit button based on the existence of a variable. See VarIF and IfStatements for details on conditional text. See PatternSkinCustomization entry point.

Working under the assumption that IF I can get this to work, I might be ablle to convince the Powers That Be to add a template, I tried to follow the instructions at PatternSkinCustomization. My test is here. APparently I'm doing something wrong.

I created a file named templates/view.noedit.tmpl containing the 3 lines as suggested. Then I

   * Set COVER = %IF{ "$ WIKINAME='VickiBrown'" then="pattern" else="noedit" }%

I see

   • Set COVER = pattern

   • Set COVER = noedit

What am I doing wrong?

You must write the template exactly as documented, with INCLUDE "view.pattern" instead of "view":

%TMPL:INCLUDE{"view.pattern"}%
%TMPL:DEF{"topicaction"}%%TMPL:END%
%TMPL:DEF{"toolbar"}%%TMPL:END%

COVER is documented in TWikiSkins

But you cannot use %IF% to set a variable. I think the best solution would be to set COVER to noedit in Main.TWikiPreferences, and to set an overriding COVER in your user topic to pattern.

> You must write the template exactly as documented,

I did write it (copy/paste) that way. I just double checked. I don't know how the text got munged in my (now fixed) verbatim section of my example page but the actual template is identical to the documented sample.

IF{ }: Empty expression to set a variable.

Oh drat. Well, that would be the problem.

Actually, "pattern" is the standard. I suppose I could do that but it worries me. It means that somehting i'm trying for one or two pages is causing me to add code that affects everyone in the entire web. I can't accept that.

Looks like time for a TWIki enhancement request. (Can't use IF to set a variable?????)

I had a similar issue. I wanted to change the background color of restricted topics when they were viewed by our staff. At first, I tried setting the COVER variable with an IF statement, but that didn't work. I ended up creating a new pattern skin called view.restrictedmanual.tmpl and adding this line to it:

<div id="patternMain">%TMPL:P{"topbarspacer"}%
%IF{
 "$WIKINAME ingroup 'MegasysEmployeeGroup'"
 then='<div id="patternMainContents" style="background-color:#FFD6C0;">'
 else='<div id="patternMainContents">'
}%

Then, I set COVER = restrictedmanual in each of the restricted topics.
