Hi i get this error “Encountered “categories” in payload, but no model was found for model name “category””

Data I get from the API:-

{
	"categories": [{
		"id": 6737,
		"category_id": 1,
		"product_id": 3954,
		"product": {
			"id": 3954,

	}, {

		}
	}],
	"paging": {

		"nextPage": true,

	}
}

My categories.js serializer

import DS from 'ember-data';

export default DS.RESTSerializer.extend({
    normalizeResponse(store, primaryModelClass, payload, id, requestType) {
        //console.log(payload.categories);
        payload = {
            categories: payload.categories
        };

        //console.log(payload);
        return this._super(store, primaryModelClass, payload, id, requestType);
    }
});

When I View categories page i get bellow warning and did not print any data

WARNING: Encountered "categories" in payload, but no model was found for model name "category" (resolved model name using (unknown mixin).modelNameFromPayloadKey("categories"))

What does your ‘category’ model look like?

Oh wait… if you have a ‘categories’ serializer I’m guessing you also named your model ‘categories’. Ember does automagic inflection matching. So basically all model names should be singular. So I would change your model/serializer name to ‘category’.

Thanks for your reply. It’s very helpful :slight_smile:

I should also note that Ember is smart enough to change the request URLs for you, so if your model name is “category” but you make a findAll request it will hit ‘/categories’ or if you do a findRecord it will hit ‘/categories/:id’ by default.
