Mohammad,
I am quite interested in the coding methods you are using. I thought this
was an appropriate place to share other methods of adding fields to
tiddlers, part of "creating a tiddler".
The "just in time field addition" is where your view template allows you to
edit, thus create fields when and if required, rather than creating them
before hand. The edit or checkbox etc... does the field creation for you.
Of course you need to do this via a template so you can "edit the current
Tiddler".
I have a commercial project where I am doing this, the customer asked for
additional checkboxes on a person record. Since I expect they will want
more in the future I used a Dictionary tiddler to store field names and
description, then need only add another to have it appear in their person
tiddlers.
<$list filter="[[$:/data/industry-experience-fields]indexes[]]"
variable=fieldname>
<$checkbox field=<<fieldname>> checked="yes" unchecked="no"
default="no"> <$text text={{{ [[$:/data/industry-expierence-fields]getindex
<fieldname>] }}}/></$checkbox><br>
</$list>
So in this case the field will only exist if given a value, so my report
logic will test if yes OR "no"/blank.
I am working on a code pattern for generic way to allow edit current
tiddler elements. I have more complex solutions but would like to make it
easy to use.
Regards
Tony
