Ember - Cli , Rails API JSON API FORMAT , AMS 0.10.0 rc Not Working

Still stuck in the basics , with the JSON API , AMS, RAILS....

I covered ember with some books like "Rock and Roll with ember js" , "Ember-cli" But here is a scenario where i need to put some has_many / belongs_to relationship with some data...

In My Ember Application

models/customer.js

export default DS.Model.extend({
name: DS.attr('string'),
contactname: DS.attr('string'),
contactno: DS.attr('string'),
othcontactno: DS.attr('string'),
othrefdetails: DS.attr('string'),
projects: DS.hasMany('project'),
});

models/project.js

export default DS.Model.extend({
  name: DS.attr('string'),
  customer: DS.belongsTo('customer' , {async:true}),
  agent: DS.belongsTo('agent' , {async:true})
});

adapters/application.js

export default DS.JSONAPIAdapter.extend({
  host: 'http://localhost:3000',
  shouldReloadRecord(store, snapshot) {
    return false;
  },
});

serializers/applicaiton.js

 export default DS.JSONAPISerializer.extend({
 });

And in my Rails api

class Project < ActiveRecord::Base
   belongs_to :customer 
   #belongs_to :agent
   #has_many :enquiries
   accepts_nested_attributes_for :customer
end


class Customer < ActiveRecord::Base
   has_many :projects
   accepts_nested_attributes_for :projects
end



class ProjectSerializer < ActiveModel::Serializer
  attributes :id, :name
   belongs_to :customer
   #has_one :agent
   #has_many :enquiries
end


class CustomerSerializer < ActiveModel::Serializer
  attributes :id, :name, :contactname, :contactno, :othcontactno, :othrefdetails
    has_many :projects
end

initializers/json_api.rb

ActiveModel::Serializer.config.adapter = ActiveModel::Serializer::Adapter::JsonApi

Gem File (I am using 0.10.0 rc3 due to some bugs in 0.9 version)

gem 'active_model_serializers' , '~> 0.10.0.rc3'
 # gem 'active_model_serializers' , '~> 0.9.3'

I am getting a json response for localhost:3000/customers From The rails api like this

{"data":[{"id":"6","type":"customers","attributes":{"name":"Talhaqqq","contactname":"Mohammed Talha","contactno":"9744878171","othcontactno":"+9104735253585","othrefdetails":"nil"},"relationships":{"projects":{"data":[{"id":"1","type":"projects"}]}}},{"id":"10","type":"customers","attributes":{"name":"Ameer Ali qq","contactname":"Ameer Mohammed Ali","contactno":"234234","othcontactno":"439870987","othrefdetails":"othr ref detaila"},"relationships":{"projects":{"data":[]}}},{"id":"67","type":"customers","attributes":{"name":"Signlab qqq","contactname":"Sigblab contact","contactno":"2340987","othcontactno":"sjfdla98","othrefdetails":"s098-"},"relationships":{"projects":{"data":[{"id":"2","type":"projects"}]}}},{"id":"68","type":"customers","attributes":{"name":"Anwar Nazar","contactname":"Anwar","contactno":"2+87+968","othcontactno":"354+641+9","othrefdetails":"31651651"},"relationships":{"projects":{"data":[]}}},{"id":"69","type":"customers","attributes":{"name":"Cust name qqq","contactname":"asdfda","contactno":"sdfsdf","othcontactno":"sadfafd","othrefdetails":"asfdgadfg"},"relationships":{"projects":{"data":[]}}},{"id":"70","type":"customers","attributes":{"name":"dsasva","contactname":"a","contactno":"sdfvsfva","othcontactno":"asdv","othrefdetails":"vafasdfv"},"relationships":{"projects":{"data":[]}}},{"id":"71","type":"customers","attributes":{"name":"egrweg","contactname":"aevg","contactno":"asdgr","othcontactno":"aergarg","othrefdetails":"saerg"},"relationships":{"projects":{"data":[]}}}]}

I am trying to set a customer for a project....

I tried it manually in one of the routes actions.... (I dont know the best way to do it in ember ).. None of the tutorial books tells about setting relationship data

let project = this.store.peekRecord('project', 3);
let customer = this.store.peekRecord('customer', 6);
project.set('customer', customer ); 
project.save();

And i am getting this on rails

  Parameters: {"data"=>{"id"=>"3", "attributes"=>{"name"=>"Xyy project"}, "relationships"=>{"customer"=>{"data"=>{"type"=>"customers", "id"=>"6"}}}, "type"=>"projects"}, "id"=>"3"}

I tried to permit the relationships, attributes in Projects_controller

params.require(:data).permit!
#  params.require(:data)
# .permit(:id ,   :attributes => [:name] , :relationships => [:customer => [:data] =>[:type] ] , :customer => [:data] )

But nothing worked well .. always given unpermitted parameter... and i ended up permitting all params using

params.require(:data).permit!

And finally , When i did the update using this function

  def update
    @project = Project.find(params[:id])
    @customer = Customer.find(6)
    @project.update_attributes(:customer => params[:customer])
    if @project.update(project_params)

      head :no_content
    else
      render json: @project.errors, status: :unprocessable_entity
    end
  end 

I got this response in rails customer_id = NULL..

I know i am totally confused,, I tried to use AMS 0.9 version without the JSON API Standard , but ended up in stack level too deep error and come other problems.

But using the AMS 0.10.0 rc version and standard JSON API Format, i couldn't find any tutorials or answers for these questions..

1. How to set relationship data in ember ?
2. The best json format from API (standart json / json with embed ids )?
3. How to allow strong parametes in Rails (Especially nested with relationships{id, type} etc... With STANDARD JSON API FORMAT)?
4. Update relationship (update attributes ) in Rails with the json api request from ember?
5. Is it best to go with the JSON API FORMAT , and AMS ...AND JSON API ADAPTER /SERIALIZER...

It feels some thing like an eclipse should happen with these things to work all together...
