Add Ember Data query helper method

Question

I'm using Ember API with a JSON API backend. The API accepts filters like this:

/users?filter[simple][name]=John

Right now, whenever I want to make a query, I'm doing this:

this.store.query('users', {
  filter: {
    simple: {
      name: 'John'
    }
  }
});

It would be nice to avoid this verbosity by adding a helper function that works like this:

this.store.simpleQuery('users', { name: 'John' });

That function would pass its arguments directly to query(), just wrapping the query in { filter: { simple: ... } }.

Is this possible? How do I do this?

Well what is stopping you from creating your own method in the adapter to do exactly that?

// ... your adapter code 

simpleQuery: function(modelName, query) {
    return this.store.query('users', {
        filter: {
            simple: {
                name: 'John'
            }
        }
    });
}

// ...

You need to extend the default store. Add the following to app/services/store.js

import DS from 'ember-data';

export default DS.Store.extend({
  simpleQuery(modelName, query) {
    return this.query(modelName, {
      filter: { simple: query }
    });
  },

  simpleQueryRecord(modelName, query) {
    return this.queryRecord(modelName, {
      filter: { simple: query }
    });
  }
});

And you'll be able to do this:

this.store.simpleQuery('users', { name: 'John' });
this.store.simpleQueryRecord('users', { email: '[email protected]' });
