Hey Ad F.!
Ah! I think the problem isn't the paginator, but Doctrine (well really SensioFrameworkExtraBundle) is unable to figure out how to query for your "Advert" entity. My guess is that you have a route that ...
... connection. Here is some deep logic that proves this: https://github.com/doctrine/DoctrineBundle/blob/master/DependencyInjection/DoctrineExtension.php#L338-L342
So, the best option I can think of to "enforce" being explicit ...
... get all related comments in one query, then it somehow hydrates the relevant post with it's comments. So only 2 queries are needed. Is there a similar way to do this with Doctrine? I'm not sure how I would optimize this manually, since the foreign key ID fields are hidden.
... you can paste directly into MySQL to see the results that Doctrine is getting.
If the order is definitely wrong, and you can't find any issues, you can post your code and we can see if we spot any problems :).
Cheers!
... that this question is out of a course scope, but does anyone one know a reason for existing of owning and inverse side of Doctrine relations? Can we make an equal sides of association (to CRUD entities from both sides without additional actions)?
... with you: generated entity code could not check all the schema nuances, especially after several controversial changes. And that's why there was a good practice of removing all the autogenerated code in the entity and recreation it by the doctrine command or IDE.
... - is it possible to run doctrine migrations from within the application and not via the terminal? (If not, I'll just put together a script that cycles through all the databases and runs the migrations command)
... OneToMany and ManyToOne that technically is the same as ManyToMany in the database, but now we can add extra data (add extra columns on GenusScientist) to this intermediate table with Doctrine. I hope it clear to you now. I'd also recommend to re-watch this video one more time because yeah, it's kinda complex.
Cheers!
... totally meant to put this in my original code - sorry!
