[tw5] Re: Linking to Field Values
@Eric Shulman Great, that works, thanks! Really minor follow-up question.
What do I have to put before [field:father-id{!!id}] to get it to actually
show up on the page as text and a link?
Currently, I can do this: <> (which is
the inverse, for finding fathers as opposed to finding sons) but that
produces a list e.g.
- Robert Smith
I just want it to show
Robert Smith
Because people only have one biological father! I think the <>
bit is a 'macro'? I've tried:
<[field:id{!!father}]>
<<[field:id{!!father}]>>
<<$link [field:id{!!father}]>>
<$link to=[field:id{!!father}]>[field:id{!!father}]
All with no luck.
Slightly more general question, I've found myself a bit baffled by
macros/whatever they are. TiddlyWiki as loads of examples of operators, but
unless you know what you need to put before them, they aren't actually
usable! For example, I know the subtract operator looks like this:
[[23]subtract[19]]
But obviously, just putting that in a tiddler doesn't produce the value
"4", you have to put something before it. I've got no clue what that should
be, and the code actually used in the wiki:
<<.operator-example 1 "[[23]subtract[19]]">>
Does not work.
Sorry to dump loads of questions! I just get the impression that TiddlyWiki
is incredibly powerful and perfect for my use-case, but there is a lot of
basic syntax stuff that I just don't get.

When specifying the parameter value for a filter operator, *the type of
brackets indicate the kind of parameter value* you are using:
square brackets are for *literal* values, e.g.
[field:father-id[634750-LiR]]
angle brackets are for *variable* values, e.g.,
[field:father-id]
curly braces are for *field references*, e.g., [field:father-id{!!id}]
Also note that within filter syntax, use *single* brackets/braces, rather
than the *doubled* brackets/braces that are used within regular wiki text
syntax;
i.e., [634750-LiR] instead of [[634750-LiR]], instead of
<>, and {!!id}} instead of {{!!id}}

[tw5] Re: Linking to Field Values
Sorry, supplemental question involving using fields¬
Another thing I want to do is use id and father-id / mother-id fields to
automatically list the children of an individual. Ids are preferable to
just names/titles, because of the chance of duplicate names.
How it might work is this. Say Robert Smith has two sons, John Smith and
Peter Smith. That could be represented in fields like this:
(John Smith fields)
id: 365974-LlO
father-id: 634750-LiR
(Peter Smith fields)
id: 571157-OnU
father-id: 634750-LiR
(Robert Smith fields)
id: 634750-LiR
father-id: 612745-GbF
Now doing this <>
Works to retrieve the children of Robert Smith. However, that involves
manually typing in Robert Smith's id. Instead I want something like
this: <>
But that doesn't work...

[tw5] Re: Linking to Field Values
Thank you so much @Soren Bjornstad, that works perfectly! I think I tried
something close to that at one point, I just messed up the syntax!
@iamdar my use case is that I want to be able to mass-produce
wikipedia-style bios for individuals, where the the same basic info comes
up in multiple parts of the 'article'/tiddler.
For example, in the opening line, it might say "John Smith was born in
MadeupLand", the side bar might also mention he was born in MadeupLand. If
I link both references to MadeupLand through a field i.e. using <$link
to={{!!birthcountry}} /> then I only have to specify the country John Smith
was born in once, in the field. If I iterate this process 100 times (using
the same code for most of the body of the article, just customising it with
novel information) it saves a lot of typing.
Another advantage is that it makes it easier to call groups of people who
share a particle bit of vital information, without necessary creating a tag
for, say, "born in 1872" (which, I could do...it just seemed clunky?). The
main example that comes to mind is using surnames as a way to list every
individual from a particular patrilineal lineage (assuming it's an unusual
surname that unrelated individuals are unlikely to share within my
group...I could also have a specific familyID field).

[tw5] Re: Linking to Field Values
@merry.ma I just had a quick question about your process. I was wondering why you were using a field in the tiddler instead of [[MadeupLand]] to create a link? Or, I suppose for that matter, why not simply put the like you had? Not trying to be rude, truly just being curious about your process. Is there a particular reason or benefit you get from using the value of a field? Thank you!

[tw5] Re: Linking to Field Values
Hi Merry,
This isn't valid XML/HTML/wikitext:
<$link to=<$view field=birthcountry/>
You can never nest widgets within attributes of other widgets like this
(side note: notice that even if this was allowable, you would be missing a
closing > after the /> to finish the opening $link tag). More generally, it
might be worth learning now that in an attribute like to=, you can do
exactly one of four things in TW:
- to="constant value" [see note 1]
- to={{field transclusion}}
- to={{{filtered transclusion}}}
- to=<>
Any combination of these, or any other content, won't work. Here's a summary
of the available transclusion syntax
.
Fortunately, there's no need to use a $view widget here – you can just
transclude the field with the double-brace syntax:
<$link to={{!!birthcountry}}/>
[1] There are three other ways you can quote the value: """triple
quotes""", 'single quotes', and sometimes no quotes at all (if there aren't
any spaces or special characters in the value).

Try this:
