Conditionally trigger action-createtiddler using a List Widget

[Lisa Wasserman]

I'm still trying to automatically create a new tiddler if one of the required title doesn't exist.  My existing code is as follows:

\define journalTiddlerName( ) $(when)$ $(project)$

\define state() $:/state/$(currentTiddler)$

\define createTodaysEntry()

<$action-createtiddler $basetitle=<<journalTiddlerName>> tags="journal $(project)$" project=$(project)$ description="$(description)$" />

\end

<$vars project={{!!project}} description={{!!description}} when=<<now DD-MMM-YYYY>> >

<$list filter="[title<journalTiddlerName>] +[is[missing]] +[limit[1]]">

<<createTodaysEntry>>

</$list>

</$vars>

While I could get the list widget to display different strings, dependent on whether the tiddler existed, I could not create a new tiddler.  After a little reading, it seems that Action Widgets need to be triggered specially.  Is there a simple method that I can use to trigger my action-createtiddler, inside of my list widget?  I don't want to have to press a button, when I always want to create a tiddler if it doesn't already exist.

Quick tip: Wrapping even a list that contains actions widgets with a button is sufficent to trigger that action for every item in the list.

\define journalTiddlerName( ) $(when)$ $(project)$
\define state() $:/state/$(currentTiddler)$
\define createTodaysEntry()

<$action-createtiddler $basetitle="$(journalTiddlerName)$" tags="journal $(project)$" project=$(project)$ description="$(description)$" />

\end

<$vars project={{!!project}} description={{!!description}} when=<<now DD-MMM-YYYY>> >

<$button>

<$list filter="[title<journalTiddlerName>] +[is[missing]] +[limit[1]]">
<<createTodaysEntry>>
<

/$list>
Create <<journalTiddlerName>>
</$button>
</$vars>

Note that I changed the reference to 

$basetitle="$(journalTiddlerName)$"

Perhaps you could add 

https://tiddlywiki.com/#ActionNavigateWidget to open the tiddler as well.

FYI when you use a value in the current tiddler to create a new one with the same values such as project I have started calling this "in context", I plan to release a "context tool" one day.

TonyM,

What role does the state macro play? I don't see it called anywhere.

Thanks!

It was part of the larger chunk of code that I was working on.  I separated this piece out, trying to get it to work.

Ah! Thanks for clarifying.

[Lisa Wasserman]

Thank you!  That solved it nicely.  I already had a button that allowed me to switch between editing and viewing the tiddler.  I moved the list inside of the macro, then put the macro call inside of the button that put the tiddler into edit mode.  Here's what I ended up with:

\define journalTiddlerName( ) $(when)$ $(project)$

\define state() $:/state/$(currentTiddler)$

\define createTodaysEntry()

<$list filter="[title[$(journalTiddlerName)$]] +[is[missing]] +[limit[1]]">

<$action-createtiddler $basetitle="$(journalTiddlerName)$" tags="journal $(project)$" project=$(project)$ description="$(description)$" />

</$list>

\end

<$vars project={{!!project}} description={{!!description}} when=<<now DD-MMM-YYYY>> filterwhen=<<now YYYY0MM0DD0hh0mm>>>

<$reveal type="nomatch" state=<<state>> text="show">

<p><h1>Today <$button set=<<state>> setTo="show" class="tc-btn-invisible" style="fill:#00aaaa;">{{$:/core/images/edit-button}}<<createTodaysEntry>></$button></h1></p>

<p><$transclude tiddler=<<journalTiddlerName>> mode="block" /></p>

</$reveal>

<$reveal type="match" state=<<state>> text="show">

<p><h1>Today <$button set=<<state>> setTo="hide" class="tc-btn-invisible" style="fill:#00aaaa;">{{$:/core/images/done-button}}</$button></h1></p>

<p><$tiddler tiddler=<<journalTiddlerName>>>{{||$:/core/ui/EditTemplate/body/editor}}</$tiddler></p>

</$reveal>

</$vars>

Great,

Using buttons as a trigger around otherwise complex lists containing action widgets is a powerful code pattern to learn.

Its a good way to make buttons to do batch changes on tiddlers, this allows one to redesign your wiki. Like using tags to set a field then delete the tag as one example.
