[tw5] Re: Using data dictionary for variable lookup

[Chris Brouwer]

Thanks! That's the trick!

I now use this second version. I will use this info to learn form it.

I had not thought of the possibility to use the filter-syntax to set the 
value.

[tw5] Using data dictionary for variable lookup

[Chris Brouwer]

Hello all,

I have the following situation, but can't acheive my goal. What am I doing 
wrong here ?

I hav a Datatiddler containing country codes (abbreviations) as indices and 
a sort code as values, like this:

CZ:01
SK:02
HU:03
RO:04
SRB:05

I have a tiddler with a Select widget, where I let the user choose a 
country code.
The resulting code is correctly placed in the "country" field. So far so 
good.

Here's the catch:
I also would like to place the sort code in a seperate field of the same 
tiddler. But accessing the DataTiddler seems to work only when I use a 
hardcoded countrycode, like {{landcodes##RO}}.

But what I would like is: {{landcodes##<>}}, or whatever way to get 
to the correct value. I have tried constructs with "<<", "$(", '"""$' but 
nothing seems to do the trick.

Any suggestions ?

Here is the contents of my test-tiddler:
-
\define update-sort()
<$vars lnd={{!!land}} >
<$action-setfield $tiddler=<> $field="sort" 
$value={{landcodes##<>}} />

\end

\define getLand()
<$select tiddler=<> field="land" actions=<> >
  <$list filter='[[landcodes]indexes[]sort[title]]' listItem=selectedList >
  >><$view field='title'>
  

\end

[tw5] Re: List macro says: No result, where Advanced Search finds tiddlers

[Chris Brouwer]

Thanks very much, Mark!

I have tried something like this, but probably still made a mistake 
somewhere.

This is working as expected.

[tw5] Re: List macro says: No result, where Advanced Search finds tiddlers

[Chris Brouwer]

Hello Mark,

I already tried that construct, with the same result.

I add the tiddler here, and a screenshot of the output.

Still, with my version of the code, this is the filter it shows: **
[tag[Overnachting]trip[Balkan 2019]sort[title]]** (Without the '**', of 
course ;-) )
So that looks like it does work (construct the correct filter, I mean). 
When I feed that to Advanced Search,, it gives me the expected reults. The 
<$list> does not.

[tw5] Re: List macro says: No result, where Advanced Search finds tiddlers

[Chris Brouwer]

Hello Ton,

allthough this is enlightening for me, the situation is a bit more complex.

I am trying to adapt a little bit of Mario Pietsch's excellent work, just 
to include 1 extra filtering parameter.

Here is (most of) the code I changed:

\define createTripFilter(tag:"" trip:"" prefix:"")
[tag[$tag$]trip[$trip$]sort[title]]
\end

\define list-body(tag:"" trip:"" prefix:"")
--
"""$tag$"""
"""$trip$"""
<>
--

Naam
Keuze
Prijs
Periode

<$list filter=<> emptyMessage="Niets gevonden">
<>
<>
<>
<>


\end

<>


I am using Tiddlywiki 5.1.19.

The tiddlers I am looking for contain the tag "Overnachting", and the name 
of the trip in the field "trip".

[tw5] List macro says: No result, where Advanced Search finds tiddlers

[Chris Brouwer]

Hello all,

I am trying to produce a list of tiddlers, filtered based on 1 tag and the 
contents of 1 field, inside a macro.

For debugging purposes I output the separate parts, as well as the 
constructed filter.

Everything looks as I expect it. But the macro still comes up with an empty 
list.

So ofcourse I tried the exact same filter in Advanced Search (Copy/Paste 
from the debugging output), and this time I do get the results I want, not 
an empty list.

Why is TiddlyWIki list widget giving me a different result ?

I have tested with a combination of 2 tags, with and without spaces, but 
the results are consistent.

Any thoughts ?
