將current_user與來自Rails中API調用的json響應相關聯

Question

我需要將當前用戶與我在PostgreSql 9.4中捕獲並存儲的json響應綁定在一起。 我正在使用Rails4。我能夠成功地將json存儲在json數據類型的“返回”列中。 我已經采取措施來創建模型關聯並更新了架構，並且我有一個帶有記錄的用戶模型，但是user_id在保存json返回的Document記錄中仍然為nil。 我列出了控制器，因為我幾乎確信我的問題就在這里。

require 'alchemyAPI/alchemyapi'
require 'json'

class AlchemyController < ApplicationController

def index
  @documents = Document.all
end

def create
  alchemyapi = AlchemyAPI.new()
  response = alchemyapi.combined('url', params[:q],  {'extract'=>'page-image, title, author, concept' })
  puts JSON.pretty_generate(response)

if 
  Document.create(result: response)
  flash[:notice] = "Input was successfully analyzed and persisted."
  redirect_to action: 'index'
else
  flash[:notice] = "Input was successfully analyzed and persisted."
  redirect_to action: 'index'
end
end
end

Answer 1

解決的方法是按照if塊的前兩行中的說明添加當前用戶。

def create
 alchemyapi = AlchemyAPI.new()
 response = alchemyapi.combined('url', params[:q],  {'extract'=>'page-image, title, author, concept' })
 puts JSON.pretty_generate(response)

if 
 *@user = current_user*
 *@user.documents.create(result: response)*
 flash[:notice] = "Input was successfully analyzed and persisted."
 redirect_to action: 'index'
else
 flash[:error] = "There was a problem analyzing your input."
 redirect_to action: 'index'
end
end
