Question

我正在制作一个余烬和铁路应用程序。

我正在尝试向http://localhost:3000/candidates发帖请求

我的要求是200，正在创建一条记录，但一切都为零：为什么会这样？

#<Candidate id: 15, name: nil, email: nil, created_at: "2018-08-23 22:28:07", updated_at: "2018-08-23 22:28:07">

这是我的控制器代码：

class CandidatesController < ApplicationController
  # POST /candidates
  # def create
  #   @candidate = Candidate.create!(candidate_params)
  #   json_response(@candidate, :created)
  # end

  def create
    puts "create"
    puts params
    puts candidate_params
    candidate = Candidate.create!(candidate_params)

    if candidate.save
      render jsonapi: candidate
    else
      render jsonapi_errors: candidate.errors
    end
  end

  private

  def candidate_params
    # whitelist params
    params.permit(:name, :email)
  end
end

这是我的余烬代码：

import Ember from "ember";

export default Ember.Route.extend({
  model() {
    // return this.get("store").findAll("candidate");
  },
  actions: {
    createCandidate() {
      console.log("create candidate");
      let candidate = this.get("store").createRecord("candidate", {
        id: 1,
        name: "Katie",
        email: "katie@gmail.com"
      });
      candidate.save();
    }
  }
});

我的js控制台中也出现此错误： SyntaxError：JSON输入意外结束

我正在使用'jsonapi-rails'gem

以下是服务器日志和“网络”标签的屏幕截图：

这是我的适配器：

import DS from "ember-data";

export default DS.JSONAPIAdapter.extend({
  host: "http://localhost:3000",
  dataType: "json"
});

我在前端不使用任何序列化程序。我可以做？是的，我期待jsonapi数据。

您必须在ember应用程序中定义一个模型： https://guides.emberjs.com/release/models/#toc_models

此外，如果您使用的是jsonapi规范，则应设置related adapter

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

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

and serializer

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

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

为什么保存后我的记录有所有零字段？
