Using custom field values as filter parameters

[Дмитрий Ивашкин]

Hi, I'm trying to make a filter that shows tiddlers created by a certain date.

So, I have a tiddler that has custom "day" field. Then I have an interface to change it:

<$edit-text field="day" tag="input" type="date"/>

So far, so good. Then I have a list of tiddlers that were created on the selected date:

<$list filter="[sameday[???]!is[system]]">

<$view field="title"/>

</$list>

How do I insert content of "day" field from current tiddler to the search field of the filter above? Is there a way to do that?

Hi,

I have the same problem : using a field value in a filter expression.
So far I use a macro and a variable :

At the beginning of the tiddler :

\define myFilter()

<$list filter="[sameday[$(fieldvalue)$]!is[system]]">

<$view field="title"/>

</$list>
\end

and then use it like that :

<$set name="fieldvalue" value={{!!day}}>
<<myFilter>>
</$set>

Hi, thanks a lot, that actually helps!

The only problem left for now is that <$edit-text field="day" tag="input" type="date"/> makes my 'day' field be in YYYY-MM-DD format, while filter expects it in YYYY0MM0DD.

I'm not sure what is the proper way to convert one to another. Except maybe for just changing config.views.wikified.dateFormat.

Hi,

Perhaps simpler (?) :

\define myFilter(fieldvalue)

<$list filter="[sameday[$fieldvalue$]!is[system]]">

<$view field="title"/>

</$list>
\end

and then use it like that :

<$macrocall $name="myFilter" fieldvalue={{!!!day}}/>

As for your format problem, try a simple javascript macro with String.replace()function.

Maybe should be in a separate thread. As for javascript macro, I made a "dateFormat" macro that properly converts date strings for me, but when I use it in my tiddler as:

<<dateFormat {{!!day}}>>

it gets "{{!!day}}" string literal as a parameter, not the value of field "day". Is there any sort of escaping syntax for that?

Try with the macrocall widget.

Hi,

As Danielo said :

<$macrocall $name="dateFormat" nameOfYourParameter={{!!day}}/>
