爲什麼我的記錄沒有更新？

Question

我遇到問題更新記錄，使用保存。這是我的代碼到目前爲止

def update 
    if current_user.customer? 
     question = JobQuestion.find(job_question_params[:job_id]) 
     question.answer = job_question_params[:answer] 

     # Only save, if the current user is the owner of the job. 
     if current_user.id == Job.find(job_question_params['job_id']).customer.id && question.save 
     raise JobQuestion.last.inspect 
     render json: { status: 201 } 
     end 
    end 
    end 

但由於某種原因它不會更新，這是我的日誌輸出。

SQL (85.6ms) UPDATE "job_questions" SET "answer" = $1, "job_id" = $2, "question" = $3, "updated_at" = $4 WHERE "job_questions"."id" = 2 [["answer", "safsf"], ["job_id", 2], ["question", "test test test"], ["updated_at", Wed, 08 Jan 2014 15:04:16 UTC +00:00]] 
    (11.5ms) COMMIT 
    JobQuestion Load (0.9ms) SELECT "job_questions".* FROM "job_questions" ORDER BY "job_questions"."id" DESC LIMIT 1 
Completed 500 in 218ms 

RuntimeError - #<JobQuestion id: 3, job_id: 2, company_id: 2, question: "test test test", answer: nil, created_at: "2014-01-08 11:47:34", updated_at: "2014-01-08 14:17:00">: 
    app/controllers/api/job_questions_controller.rb:27:in `update' 
    actionpack (4.0.0) lib/action_controller/metal/implicit_render.rb:4:in `send_action' 

正如你所看到的那樣，加註是提取工作問題，但答案是零，甚至認爲它是插入的東西。

我在做什麼錯了？

Answer 1

要更新的JobQuestion有id == 2，然後取與id == 3

嘗試一個使用相同的查詢來查找記錄。

JobQuestion.find(2).inspect #=> #<JobQuestion id: 2,... 
JobQuestion.last.inspect #=> #<JobQuestion id: 3,...
