[tw5] Re: Conditional Reveal based on whether tiddler title shows up in fields of other tiddlers
Hello,
That worked perfectly, thanks! I knew there was some kind of syntax trick I
was missing. Honestly, the reason for the two gender loops was just my own
confusion. Intuitively, I couldn't think of another way to list
parent-child relationships in a way that was agnostic towards which parent
it was - now I realise I could have had
<><>
and that would have worked.
Looking at it, I agree there are still possibly needless loops - although
it does the job, so I'm not complaining!
<$vars haschild="[all[tiddlers]field:mother{!!title}limit[1]]">
<$list filter="[all[current]gender[female]filter]">
''Children''
<>
<$vars haschild="[all[tiddlers]field:father{!!title}limit[1]]">
<$list filter="[all[current]gender[male]filter]">
''Children''
<>
I've tinkered with it to produce this:
<$vars
haschild="[all[tiddlers]field:mother{!!title}field:father{!!title}sum[]limit[1]]">
<$list filter="[all[current]filter]">
''Children''
<><>
Which seems to work and is a lot less wordy
Thanks a lot!

[tw5] Conditional Reveal based on whether tiddler title shows up in fields of other tiddlers
Hello!
Okay, so the context for this is that I have, or will have, a database of
many, many interrelated individuals. Each of those individuals has a
'mother' and a 'father'. I can currently get tiddlywiki to display lists of
children each individual has, based on their name showing up in the mother
or father field of another tiddler. What I can't figure out how to do is
get the 'Children' row of the table not to show when an individual has no
children.
For other fields I can do something like this:
<$list filter="[all[current]has[secondaryeducation]]">
''Secondary Education''
<$link to={{!!secondaryeducation}} />
When an individual doesn't have the secondaryeducation field, the row
doesn't show up in the sidebox.
My current set up for listing children looks like this
<$list filter="[all[current]gender[female]]">
''Children''
<>
<$list filter="[all[current]gender[male]">
''Children''
<>
<$list filter="[all[current]has[id]]">
If the individual is female, it looks for instances of the title of the
individuals tiddler being listed as the mother in other tiddlers. Vice
versa for males.
I've fiddled with lots of widgets. I think the problem is that this syntax
[field:father{!!title}] doesn't play well...
Also, if you have better alternative methods of achieving this goal, I'm
all ears! I know filling in a 'Children' field, would solve this problem,
but I want to cut manual data input to a minimum, and in principle all
biological familial relationships (siblings, aunts, grandparents...etc.)
can be expressed in mother-child, and father-child relationships.

[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.

[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] Linking to Field Values
Hello, I think this is a pretty basic problem, but I've not been able to figure out how to do it. Within tiddlywiki, I have profiles for made-up individuals. I have birthcountry of each individual recorded as a field. I also have wikipedia-style sideboxes with individuals date of birth, date of death, parentage, childrenetc and birthcountry as well. All I want to do is have it so that I can use the birthcountry field to supply a value that I can use as both text and a link to another tiddler. For example: John Smith Born - 04/05/1872 - Fantasyshire, MadeupLand (with "MadeupLand" value drawn from the field and also used link to a tiddler with the title "MadeupLand") Currently, I can retrieve the field value: <$view field=birthcountry/> And I can manually link to 'MadeupLand': <$link to="MadeupLand"> But putting them together like this: <$link to=<$view field=birthcountry/> Does not work, I just get "true" Any help would be much appreciated! -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
