当我去创建教学大纲时回滚

Question

我可以通过终端制作 CRUD 教学大纲，但是当我通过我的程序界面进行制作时，它不允许我“创建”并进行回滚。如何调试这个？我已经尝试了很多方法，我不知道到底发生了什么。最奇怪的是我总是设法通过终端来做到这一点。

我的控制器

    before_action :set_syllabus, only: [:show, :update, :destroy]

    def show
      if @syllabus
        scheduled_dates = JSON.parse @syllabus.scheduled_dates
        # interests_array = @syllabus.student_interests.pluck(:data)
        
        if current_student.status != "freemium"
          render json: {
            goal: @syllabus.goal,
            objective: @syllabus.objective,
            level: @syllabus.level,

Answer 1

错误就在那里，unpermitted parameters。您需要将 require(:syllabus) 添加到强参数中。

params.require(:syllabus).permit(
          :student_id,
          :objective,
          :level,
          :goal,
          :estimate,
          :skills,
          :scheduled_minutes
          interests: [],
          scheduled_dates: [],
        )
