Doc missing for relations-handling and faker functions

[CocoJr]

Hi,

I use your bundle and today i'm be confronted to a complicated situation with the multiple-references.

I was trying to dynamically create an user and associate dynamicly an object using the <current()> method for reference.
I follow your doc, but you never mention the impossibility tu put the <current()> at other place than the end for reference.

Exemple:

Nelmio\Entity\User:
    # ...

Nelmio\Entity\Group:
    group{1..10}:
        owner: '@user<current()test>'

If you try that, that not working. I have to put the <current()> at the end, and only at the end.

Then, i ask you if you can add documentation into https://github.com/nelmio/alice/blob/master/doc/relations-handling.md page please ?

The syntax is a bit confusing in this case to be honest and I'm not sure what the expected behaviour should be;

I would recommend to keep <current()> at the end if that works, otherwise might be worth trying to invest time into #998

Thx for your reply and sorry for this confusion.

Take this fixtures exemple:

Nelmio\Entity\User:
    user_{1..10}_test:
        owner: 'user_<current()>'
Nelmio\Entity\Group:
    group_{1..10}:
        owner: '@user_<current()>_test'

I expect in this case for the group_1, to have a relation to user_1_test by the owner propriety. For the group_2, a relation to user_2_test, etc...

But in this case, the bundle get only 1 to found the relation (so user_ and _test is not interpreted).

To solve this, i have to use this syntax:

Nelmio\Entity\User:
    user_{1..10}:
        owner: 'user_<current()>'
Nelmio\Entity\Group:
    group_{1..10}:
        owner: '@user_<current()>'

I think a simple comment in the doc to specify we can't use function for relation at the begin or in the middle of a string, but only at the end can be good.

Everything is explain here visibly: #377, but not in the doc.

Then it might just be something missing in the code and that could be fixed :) See https://github.com/nelmio/alice/blob/master/CONTRIBUTING.md#expression-language for pointers

Reading this again

But in this case, the bundle get only 1 to found the relation (so user_ and _test is not interpreted).

Is definitely a bug
