[TYPO3-mvc] sorting the values of a for-loop

[Christian Essl]

That is my opinion too. If I would have to use a custom query and seperately assign the object tot he view, instead of accessing it via it's aggregate root, it can't be the ideal way.

I found an interesting fed-ViewHelper:
http://fedext.net/viewhelpers/data/data-sorter/

Logically it would feel more right, to directly sort the values inside a loop-ViewHelper, but the dataSorter should be a quick and easy workaround.

Christian

Hi!

Another possibility is to set the sorting via TCA. But you are restricted to one column and 'ASC' is hardcoded for the sorting.
(Tim Schoch posted a hack to overcome this in this list, see: "Sorting of StorageObject's with extended foreign_sortby field")

I also used custom repository methods, but it's not satisfying either, because if I have to write a custom method everytime I need sorting, all the getters don't quite make sense anymore...

It would be so nice if Extbase respected the defaultOrderings also in getters...

Best regards,
Christian
