Ruby on rails Ruby on Rails |参数缺失或值为空：task|

我是rails的新手。 在我的第一个项目中，我决定创建一个“待办事项”应用程序。 两个小时后，我退缩了。 我的控制器：

def complete_todo
    @task = Task.find(params[:id])
    @task.complete_task = true
    if @task.update_attributes(task_params)
        redirect_to root_path
    end
end

private
def task_params
    params.require(:task).permit(:name,
                                 :description,
                                 :start_on,
                                 :finish_date,
                                 :repeat,
                                 :complete_task)
end

def complete_todo
    @task = Task.find(params[:id])
    @task.complete_task = true
    if @task.save
        redirect_to root_path
    end
end

我的路线

Rails.application.routes.draw do
  root 'tasks#index'
  resources :tasks
  get 'create_new_task',  to: 'tasks#new'
  get 'complete',         to: 'tasks#complete'
  post 'tasks/complete_todo/:id',    to: 'tasks#complete_todo', as: 'finished_task'
end

我的看法呢

- @tasks.each do |task|
    - if task.complete_task == false
        div class="panel panel-primary"
            div class="panel-heading"               
                h3 class="panel-title" = link_to task.name, task_path(task)     
            div class="panel-body" 
                div class="col-md-11"
                    = task.description
                div class="col-md-1"
                    div class="bs-glyphicons"
                        = link_to finished_task_path(task), method: :post do
                            div class="col-md-6"
                                span class="glyphicon glyphicon-ok"
                        = link_to task_path(task), method: :delete do
                            div class="col-md-6"
                                span class="glyphicon glyphicon-remove"

我想多写点，但我的英语写作能力太差了。 编辑控制器：

def complete_todo
    @task = Task.find(params[:id])
    @task.complete_task = true
    if @task.update_attributes(task_params)
        redirect_to root_path
    end
end

private
def task_params
    params.require(:task).permit(:name,
                                 :description,
                                 :start_on,
                                 :finish_date,
                                 :repeat,
                                 :complete_task)
end

def complete_todo
    @task = Task.find(params[:id])
    @task.complete_task = true
    if @task.save
        redirect_to root_path
    end
end

和编辑路线：

 post 'tasks/:id/complete_todo', to: 'tasks#complete_todo', as: 'finished_task'

我想这是路线上的问题。请帮帮我。
