I was looking for the utility which will allow binding of data object in
one format into another and was not able to find a decent declarative with
minimal code way.
What came to imagination was looking like:
<iron-ajax url="..." last-response="{{srcSections}}" />
<iron-lambda lambdas="errorCheck,name2id" from="[[selectedSection]]" to=
"{{selectedId}}" catch="errorMessage" />
<iron-ajax url="...[[selectedSection]]" last-response="{{sectionJson}}" >
<some-select value="{{selectedSection}}" from="[[srcSections]]" field='name'
/>
<script>
class...
{
errorCheck(wikiResult){ if( wikiResult.error) throw wikiResult.error;
return wikiResult; }
name2id( wikiResult ){ return wikiResult.parse.wikitext['*'] }
}
</script>
Before rushing and implementing would be nice to know *whether such
solution exists or planned?*
Not necessary with same syntax but at least with similar functionality.
Of course the beauty of lambdas are in inline capabilities and chaining.
Something like
<iron-lambda lambdas=" errorCheck, x=>x.parse.wikitext['*'] " from=
"[[selectedSection]]" to="{{selectedId}}" catch="errorMessage" />
without the need for external functions declaration.
