Need another filter

[David Gifford]

Hi all

Am trying to do a special list filter:

"List all tiddlers whose article field is the current tiddler's title."

I had

<$list filter="[article{!!title}]">

which works for one word titles, but then when the current tiddler's title is more than one word, nothing gets displayed.

[c pa]

\define List_Articles(article, template)
    <$list filter="[field:article[$article$]]">
         $template$
    </$list>
\end

<$macrocall $name="List_Articles" article={{!!title}}
template="""

    Code to be run per article such as listing the title:
    {{!!title}}

"""/>

And yes. It does seem to be overkill. I've learned to live with overkill.

Hi c pa

I probably should have included the complete list filter. I am not sure how to integrate this with what you just sent me

<$list filter="article{!!title}]">

<$transclude field="text" mode="block"/>

<span class="source"><$link field="title"><$view field="source"/> - <$view field="modified" format="date" template="YYYY MMM"/></$link></span>

<hr>

</$list>

It will be in a tiddler tagged $:/tags/ViewTemplate

Hi Dave,

I tested the filter in your OP and it worked for me with titles that have multiple words.

I also tested the full snippet and found there is a [ missing before article, but other than that, this also seems to work.

c pa's solution is pretty cool, too.

Regards,

Richard

\define List_Articles(article)
    <!-- find all tiddlers that have field article = this tiddler  -->
    <$list filter="[field:article[$article$]]" variable="article_tiddler">

        <!-- Show the contents of that tiddler  -->
        <$transclude tiddler=<<article_tiddler>> field="text" mode="block"/>
        <!-- wrap the next bit in a styled span -->
        <span class="source">
             <!-- Provide a link that will open that tiddler -->
             <$link to=<<article_tiddler>> >
                    <!-- Display the source field of that tiddler (not the title) -->
                    <$view tiddler=<<article_tiddler>> field="source"/> -
                    <!-- Display the modifed date of that tiddler -->
                    <$view tiddler=<<article_tiddler>> field="modified" format="date" template="YYYY MMM"/>
              </$link>
         </span>
         <hr>
    </$list>
\end

<$macrocall $name="List_Articles" article={{!!title}} />

okay, this is working for others but not for me.

Here is the file it is not working in. http://giffmex.org/experiments/7-22.html

Conpare the tiddler "Words", which shows the two tiddlers with that title in their articles field, and the tiddler "Reading, notes on", which does not show the tiddler that should be there.

The viewtemplate tiddler being used is $:/.ChildrenArticles

What am I doing wrong??? Any ideas?

Hi Dave,

It seems to be because of the [[ ]] brackets around the entry in the article field on the tiddler 2016-07-22 17:31:50 - if I remove them, the transclusion works, but the tags break up into separate words.

I guess this is to do with the way that you have re-used the tag mechanism. The fix probably depends on whether you need each tiddler to have multiple "article tags" (fix the template) or only one (fix the tag-like interface).

Regards,

Richard

Yes, I will have multiple items in the article field. Hmmm

Hi Dave,

I *think* you can fix it by changing the filter in the view template to [is[current]listed[article]] 

(selects the current tiddler title and then looks for that title listed in the article field of other tiddlers)

I had to fiddle for a bit to get it to work and it's bed time now, but I think it works. 

Good Luck!

Regards,

Richard

Hi Richard

Sorry for the delay in responding. My wife and I went on a two day getaway without the computer. :-)

Thank you for the snippet, it worked perfectly!

Dave
