Using a field value as the index to a data tiddler

[Linda Moss]

Hey, I've been trying to figure this out, but not getting anywhere.

How do I reference an item from a data dictionary tiddler, using the value of a field as the index?

(unsurprisingly) this doesn't work:

    {{data-tiddler##{{!!field-name}}}}

because the curlybrackets don't nest like that. Ive also tried:

    {{data-tiddler##!!field-name}}

Which is also incorrect.

I've been unable to find an alternate way to reference the data tiddler index, which would let me use the {{!!field-name}}, without nesting curly brackets. Is there a way to do this?

Thanks!

Once you get beyond a certain level of complexity, it's probably better to use widgets than wikitext. e.g

<$transclude tiddler="data-data" index={{!!field-name}}/>

Good luck!

Hi Linda, you could use the transclude widget directly ( the {{ }} syntax is just a short form of it) :

<$transclude tiddler="data-tiddler" index={{!!field-name}}/>

Ah, thanks!

I hadn't been thinking of it as a transclusion, which is why I didn't get anywhere while looking for an alternate way to access a data field.

Though in hindsight, the fact that it used the same wikitext as transclusion probably should have been a hint...
