[TYPO3-mvc] Howto check if object with a specific uid is related to an object (m:n relation)?

[Henjo Hoeksma]

Hi Roland,

what you do here is extending your object model with a property of
something it can reach already. To me that doesn't sound too clean ;-)

Since you already have the type related to your Download object, I would go
for writing a viewhelper that returns true (or the string
class="important") after giving it the objects of the download types and
checking from within your viewhelper if it exists.

Thinking DDD: do you really need to have a m:n relationship from download
to type? Can one download really have multiple types? I might not
understand what you are trying to achieve, but if it can't, make it a n:1
relationship (types can have multiple downloads, but a download can only
have one type).

Then from within your downloads controller you can simply say
{f:if(condition:download.downloadType.type=1, then:'class=Important')} ...

Kind regards,

Henjo
