无法从子控制器创建操作访问父 ID

Question

这是我的错误：找不到没有 ID 的任务

我有这个关联：

TASK has_many :appointments
appointment belongs_to :task

路线：

resources :tasks do
   resources :appointments
end

在任务展示中，（我使用部分顺便说一句）我有一个链接可以创建新的约会页面：

<%= link_to new_appointment_path(id: task.id) %>

在约会控制器中：

def new
    @task = Task.find(params[:id])
    @appointment = @task.appointments.new
    # @appointment = Appointment.new
end

def create
    @task = Task.find(params[:id])
    @appointment = @task.appointments.build(appointment_params)

    if @appointment.save
        redirect_to @task
    else
        render 'new'
    end 
end

问题在于创建操作中的这一行：

@task = Task.find(params[:id])

谁能帮帮我？

    def new
        @task = current_user.task_posts.build

    def create
        @task = current_user.task_posts.build(task_params)
        if @task.save
            flash[:success] = "Task created!"
            redirect_to @task
        else
            render 'new'
        end
    end

    def edit

        @task = Task.find(params[:id])
        @task.county_id = @task.county.id
        @task.category_id = @task.category.id

    end

    def update
        @task = Task.find(params[:id])

        if @task.update_attributes(task_params)
            flash[:success] = "Task updated"
            redirect_to @task
        else

        end
    end

    def show
        @task = Task.find(params[:id])
        @responses = @task.responses.all
        @current_appointment = @task.appointments.first

        #expiry time is start_at minus 2 hours
        @expiry_time = @current_appointment.start_at - 2.hours
        @current_time = Time.zone.now + 1.hours

        @responses.each do |r|
            if r.is_accepted == true
                @accepted_offer = r
                break
            end
        end

    end

    private

        params.require(:task).permit(:category_id, :subcategory_id, :title, :description, :pay_offer, :is_pay_per_hour, :county_id, :area_id,

    end

    def logged_in_user_worker
        unless current_user.client?
            redirect_to(root_url)
        end
    end

end

Answer 1

应该是:task_id（指定Task的id），而不是:id（指定Appointment的id）：

@task = Task.find(params[:task_id])

.erb：

<%= link_to new_task_appointment_path (@task) %>

<%= simple_form_for [@task, @appointment], html: {class: 'form-horizontal'}, wrapper: :horizontal_input_group do |b| %>

routes.rb：

resources :tasks do
  resources :responses, :appointments, :subcomments
end

:appointments 不应该拥有自己的资源。
