Item5146: EDITTABLE plays Too nicely with SEARCH
Priority: Enhancement
Current State: Closed
Released In:
Target Release: n/a
I ran into an "interesting" interaction between EDITTABLE and
SEARCH.
Let's say you have a table like this
| *Project* | *Assignee* | *Launch Date* | |
%SEARCH{search="META:FIELD.*?AssignedTo.*?VickiBrown.*" topic="Projects_.*" format="| $formfield(ProjectName) | $formfield(AssignedTo) | $formfield(LaunchDate) |" }%
It returns all Project pages where
AssignedTo is
VickiBrown. Standard TWiki Forms search. No problem.
Then, lets say someone edits the page.
%EDITTABLE{}%
| *Project* | *Assignee* | *Launch Date* | |
%SEARCH{search="META:FIELD.*?AssignedTo.*?VickiBrown.*" topic="Projects_.*" format="| $formfield(ProjectName) | $formfield(AssignedTo) | $formfield(LaunchDate) |" }%
What I expected to happen:
There is only one "real" table row here. Everything else is virtual, ephemeral, dynamic. I would expect clicking the edit button to show a table with no rows except the header and the ability to add one or more rows above the Search results.
What actually does happen:
EDITTABLE merrily picks up the Search results and presents them as an editable table. When you save, it writes these (now static) rows into the page. They are immediately followed by the Search results.
If
SEARCH returns four rows, following an edit, you now see 8. Then 12. Ever recursively down the Rabbit Hole we plunge. Yargh!
I realize that the quick response is "don't hold your arm like that". But it would be nice if TWiki (in the person of
EditTablePlugin) could help protect the naive user from his own error by not picking up the "dynamic" rows returned by Search!

This can actually be (mis)used as feature for capturing search results.

Do you have any idea yourself how we could 'protect' the
SEARCH variable? I don't find it very obvious.
footerrows
cannot be used as the number will vary with the search.
%EDITTABLESTARTPROTECT%
and
%EDITTABLESTOPPROTECT%
looks ugly. The plugin cannot detect that the
SEARCH should be protected by itself. Moreover it may be intended.

Franz - agreed. But my guess is that intentional capture is less likely than misuse. The people at my company simply didn't realize what they were doing.
Arthur - If it were me, I would think that EDITTABLE and
SEARCH would need to cooperate. So, by defaulkt,
SEARCH would produce some hidden information, perhaps in the form of an HTML comment, that EDITTABLE would see and use to ignore that section of the table. A
SEARCH parameter could be used to allow editing of
SEARCH results for those who understood the ramifications.

That would mean there need to be a PROTECT variable. I favor TWiki syntax over html comments.

Unsurprisingly
EditRowPlugin suffers from the same disease.
I think it would be a mistake to lard the text with more variables. Much better to tell the
EditTablePlugin and
EditRowPlugin that only a subset of the rows in the table are editable. For example, %EDITTABLE{editablerows="1"}%. The value of
editablerows
could be a range expression (perhaps even disjoint?) for example %EDITTABLE{editablerows="1:3,-2:-1"}% would indicate that rows 1, 2 and 3 are editable, and so are the last 2 rows in the table (-2 and -1).

Looks very geeky.

Fixed with
Item1292. Without geeky syntax.
