Question

我创建了一个任务模型，除了我去删除任务之外，一切正常。即使在数据库中没有任务，@ wood.tasks.length仍为1，也会发生奇怪的事情。

_task.html.erb

<%= link_to 'MARK COMPLETED', plant_task_path(@plant, task), method: :delete %>

以下是我工厂展示的代码

<div class="col-md-4">
  <div class="jumbotron">

    <%= render 'tasks/form' %>
    <% if @plant.tasks.length != 0 %>

        <%= render @plant.tasks %>

    <% end %>
    <%= @plant.tasks.length %>

  </div>
</div>

创建任务的表单：

form_for([@plant, @plant.tasks.build])

我的路线：

resources :plants do
  resources :tasks

Rake Routes：

complete_plant_task PATCH  /plants/:plant_id/tasks/:id/complete(.:format) tasks#complete
    plant_tasks GET    /plants/:plant_id/tasks(.:format)              tasks#index
                POST   /plants/:plant_id/tasks(.:format)              tasks#create
 new_plant_task GET    /plants/:plant_id/tasks/new(.:format)          tasks#new
edit_plant_task GET    /plants/:plant_id/tasks/:id/edit(.:format)     tasks#edit
     plant_task GET    /plants/:plant_id/tasks/:id(.:format)          tasks#show
                PATCH  /plants/:plant_id/tasks/:id(.:format)          tasks#update
                PUT    /plants/:plant_id/tasks/:id(.:format)          tasks#update
                DELETE /plants/:plant_id/tasks/:id(.:format)          tasks#destroy

我的任务控制器

def create
  @task = @plant.tasks.create(task_params)
  redirect_to @plant
end


private 
def set_plant
  @plant = Plant.find(params[:plant_id])
end

def set_task
  @task = @plant.tasks.find(params[:id])
end

我得到了这个我的踪迹

我整晚都试图想出这个。任何人都可以帮我解决这个问题吗？非常感谢
