no total_pages in meta response

Hello,

First, I must say that this library is pretty cool and is a big help in getting set up with some new Ember projects I’m working on.

Unfortunately, I am receiving some errors when trying to use a model with a DS.ActiveModelAdapter backend.

Just for reference here is some code:

// adapters/application.js
import DS from 'ember-data';

export default DS.ActiveModelAdapter.extend({
  namespace: 'api',
  host: 'http://localhost:3000'
});

// controllers/users.js
import Ember from 'ember';

export default Ember.ArrayController.extend({
  queryParams: ['page', 'perPage'],
  pageBinding: 'model.page',
  perPageBinding: 'model.perPage',
  totalPagesBinding: 'model.totalPages',
  page: 1,
  perPage: 20
});

// /models/user.js
import DS from 'ember-data';

export default DS.Model.extend({
  lastName: DS.attr('string'),
  firstName: DS.attr('string'),
  email: DS.attr('string'),
  clockEvents: DS.hasMany('clock-event')
});

// /routes/users.js
import Ember from 'ember';

import RouteMixin from 'ember-cli-pagination/remote/route-mixin';

export default Ember.Route.extend(RouteMixin, {
  perPage: 20,
  model: function(params) {
    params.paramMapping = {
      page: 'page',
      perPage: 'per_page',
      total_pages: 'Total-Pages'
    };
    return this.findPaged('user', params);
  }
});

In my users template I am able to iterate over the paged array of users and I set a paginator with:

{{page-numbers content=model

It is able to get the current page and show arrows, however the “next” arrow is grayed out (though I can still click on it). In the console I have a number of warnings:

ember.js:15373 no total_pages in meta response
ember.js:15373 Object {}
ember.js:15373 no totalPages for page-numbers
ember.js:15373 no int for totalPages val is undefined
ember.js:15373 no int for totalPages val is NaN
9ember.js:15373 no int for totalPages val is NaN

Here are some sample headers in the response from my API server:

Access-Control-Allow-Credentials:true

Total-Pages:8
Vary:Origin
X-Request-Id:dfa3771e-dc5d-4496-8748-8f8c9b3fe5ee
X-Runtime:0.045344

Originally the pagination stuff had X- prefixes, but it didn’t work so I tried removing the prefix to see if it would improve the situation but it doesn’t seem to have.

The params.paramsMapping seems to have an affect for the perPage but I don’t think it’s working for the total_pages part.

If anyone can point me in the right direction or give me some advice I’d greatly appreciate it. I am still very new to Ember so I might be missing something obvious.

Thanks!

@shanekoss I’m using Rails 5.0 with Active Model Serializers and kaminari for pagination on the backend side, as well as the ordinary JSONAPIAdapter on the frontend side. Changing total_pages to total-pages should work just as you see it in the first post of this thread. Here’s some code for a model called statistic/broadcast:

  model: function(params) {
    params.paramMapping = {
      total_pages: "total-pages"
    };
    return this.findPaged('statistic/broadcast', params);
}

Unfortunately, I haven’t used AMD (or Rails) in a while so I do not recall the specifics.

Sorry I couldn’t help
