Collection is not displayed if Max per page > collection.size

[mpz]

def index max_per_page = 100

paginate Bla.count, max_per_page do |limit, offset|
  render json: Bla.limit(limit).offset(offset)
end

end

IF max_per_page is more than Bla.count collection is NOT displayed on client

Thanks for reporting this. I'll look into it over the weekend.

It also can be issue on Angular side, is not it?

[begriffs]

Sorry I haven't looked at this yet. As I mentioned in the other issue I have been pretty busy. Can you look at the gem code and suggest how to fix the problem?

[begriffs]

This bug is highly surprising since in many of the tests max_per_page is indeed much higher than the element count. Can you show me the HTTP response of your server? Perhaps your front-end display code has a bug.

Try doing

curl -I http://yourserver.com/route

which will output the payload and the HTTP headers.

With Max per page < collection.size (OK)

All times i get JSON data in response (via direct link) but in second time there are nothing on angular-side collection.

[begriffs]

Try setting Max per page > collection.size and then doing the curl without the -I option. This will display the response body and we can see if the JSON is missing.

[mpz]

I run:

curl http://0.0.0.0:3000/stream

I have valid JSON body.

Browser also recive valid JSON body but nothing are displayed in view.

I think the problem is on the Angular side.
