Grails的： <g:each> 标签，排序属性

Question

There is a way to sort in the tag in 'desc'? And is it possible to sort by two columns? I know that there is the possibility to pass the element already sorted in the controller but would be useful to have the chance also in the gsp tag.

Answer 1

Not optimal, but in a pinch you can sort the collection inline:

<g:each in="${[2,3,6,1,10].sort{a,b -> a < b ? -1 : 1}}">
${it}
</g:each>

In general I agree with mfloryan. Putting logic in the view is a slippery slope, but there's a time and a place for everything.

Answer 2

That is correct. The <g:each> tag does not support sorting and I don't think it should. Any logic (like setting sort order) should not live in the view itself.
