Hey there !
Is it possible to extend Paginator somehow with custom properties? I want it to include not only hydra:member & hydra:totalItems but a custom property. Imagine querying transactions - what I want is to receive 20 transactions per page and calculate the total value of all transactions that match the query
Cheers!

Hey Denrolya!

That's an interesting question! I've never done it before, but I believe you need a custom normalizer. When you have a paginated response, what really happens (assuming you're using Doctrine ORM) is that this class - https://github.com/api-plat... - is your "data" and then that is run through the serializer. Other normalizers - for example https://github.com/api-plat... - already look for this class (well, specifically, they usually look for PaginatorInterface) and add the properties you see. So, if you create a custom normalizer and target the Paginator class, you should be able to add new properties :).

Cheers!

Hi there,

I am implementing a custom controller with a custom action following the Api Platform Documentation (https://api-platform.com/do... for the pagination but the hydra:member of the JSON LD response is completely empty. The other fields of the pagination are correct but this one no.

Can somebody help me?

Thank you!

Raul

Hey Raul M.!

I don't have a lot of experience with custom controllers & actions. The fact that the other pagination fields are correct, but hydra:member is empty is super odd. My best advice for debugging is to try to use the paginator in your custom controller with some debug code to make sure it works. So, something like:


// ...
$paginator = new Paginator($doctrinePaginator);
foreach ($paginator as $result) {
    dump($result);
}
die;

We're checking to make sure that you can correctly iterate over the paginator and see the results. It's just a guess to try to figure out what's going wrong :).

Cheers!

Hi Ryan,

I tried to implement your custom paginator and it works, thanks!

Now I'am in hurry with my project but I will try the debbug during the next weeks because it is so strange.

Cheerio!
