[TYPO3-mvc] Related objects inheriting from parent object default query settings

[François Suter]

Hi all,

I have the following situation: I have a "Report" object which has a 
related "Owner" object, which is actually a fe_users entry. Quite 
logically I don't want to show hidden/disabled reports, but the owners 
may be disabled fe_users (former employees). To implement this, I simply 
extended the Tx_Extbase_Domain_Repository_FrontendUserRepository with my 
own class and set the enable fields to be ignored in the default query 
settings.

The problem is that when related objects are fetched (be it eagerly or 
lazily), the corresponding repository is not used, hence the default 
query settings are not used either. Instead 
Tx_Extbase_Persistence_QueryFactory::create() just looks up the storage 
pid but no more.

I have tried to work out a patch where 
Tx_Extbase_Persistence_QueryFactory::create() tries to instantiate the 
corresponding repository. This proved a bit hard as my knowledge of 
Extbase is not very deep. I have attached my draft here as I know it's 
not good enough as it is and maybe I even missed the whole point. I 
would be quite glad for feedback.

If you agree that this is indeed an issue, I will gladly accept help in 
improving this patch. In particular I'm using t3lib_div:makeInstance to 
the repository instead of $this->objectManager->create(), because I then 
get the following error:

#1265203124: Object "Tx_Foo_Domain_Repository_BarRepository" is of not 
of scope prototype, but only prototype is supported by create()

which is typically where my limited knowledge of Extbase fails me and I 
don't know how to do this properly.

Versions: TYPO3 4.5.10-dev, hence Extbase 1.3.1-dev.

Note: additionally this patch adds a test in the TYPO3 persistence 
backend when adding the storage pid condition, to avoid doing so when 
there are no pids. This is apparently a consequence of the rest of my 
patch. Maybe there's a way to avoid this, although the check seems to 
make sense anyway.

Thanks in advance for your opinion and advice.
