If you open your browser console (F12) at tiddlywiki.com and type:
$tw.wiki.getTiddler("HelloThere")
You'll get a tiddler object, that contains all the fields. ,,, If you
expand them in the explorer, you'll see, that they are protected.
By design the tiddler store contains immutable tiddler objects.
As you found out you'll need to use the $tw.wiki.addTiddler() function to
modify existing tiddlers.
So the typical workflow is like this.
- read an existing tiddler
- set your fields
- addTiddler( new Tiddler())
var tiddler = $tw.wiki.getTiddler("HelloThere"),
fields = {"myfield":"asdf aaaa bbb"}
$tw.wiki.addTiddler( new
$tw.Tiddler(tiddler,fields,$tw.wiki.getModificationFields()));
Important: see the new $tw.Tiddler() in the line above. That's the only
way to modify a tiddler.
But be aware, that the only fields that the core treats as arrays are list and
tags
So imo you'll need to explore the source code for usage examples, depending
on your usecase.
Creating a new tiddler
var fields = {"title": "my new tiddler", "text":"some text",
"myfield":"asdf bbbb"}
$tw.wiki.addTiddler( new
$tw.Tiddler(fields,$tw.wiki.getModificationFields()));
Important: If you miss the $tw.wiki.getModificationFields() you can't see
the new tiddler in the recent tab.
There are several more "init" functions in the wiki.js source code. ...
Hope that helps.
have fun!
