Question

我坚持使用JSON API，AMS，RAILS组合......

我在书中写了一些书，比如“摇滚乐与余烬”，“Ember-cli -101” 但是这里有一个场景，我需要将一些has_many / belongs_to关系与一些数据放在一起......

在我的Ember应用程序中

模型/ 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'),
});

模型/ project.js

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

适配器/ application.js中

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

串行器/ applicaiton.js

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

在我的Rails api中

Rails.application.routes.draw do
  resources :enquiries
  resources :agents
  resources :customers
  resources :projects
end

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

初始化/ json_api.rb

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

Gem文件（由于0.9版本中的一些错误，我使用的是0.10.0 rc3）

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

我正在为localhost获取json响应：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":[]}}}]}

我正在尝试为项目设置客户......

我在其中一个路线动作中手动尝试了....（我不知道在ember中执行此操作的最佳方法）..两本教程书都没有给我一个设置关系数据的最佳方法< / p>

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

我在轨道上得到这个

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

我试图允许Projects_controller中的关系，属性

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

但没有什么效果好......总是给出不允许的参数......我最终允许所有参数使用

params.require(:data).permit!

最后，当我使用此功能进行更新时

  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

我在rails customer_id = NULL ..

中得到了这个响应

   (0.8ms)  BEGIN

我知道我完全糊涂了，我尝试使用没有JSON API标准的AMS 0.9版本，但最终出现了堆栈级别太深的错误并且出现了其他问题。

但是使用AMS 0.10.0 rc版本和标准JSON API格式，我找不到这些问题的任何教程或答案..

如何在ember中设置关系数据？
来自API的最佳json格式（带嵌入ID的标准json / json）？
如何在Rails中允许强参数（特别是用关系{id，type}等嵌套...使用STANDARD JSON API FORMAT）？
使用来自ember的json api请求更新Rails中的关系（更新属性）
最好使用JSON API FORMAT和AMS ... AND JSON API ADAPTER / SERIALIZER ......

感觉有些事情就像日食会发生在这些事情上一起工作......

Ember - Cli，Rails API JSON API格式，AMS 0.10.0 rc不工作
