一旦复选框被选中，取消选中等，我就会尝试在索引上更新已完成的布尔值。
当我点击复选框时，我在控制台日志中收到“POST 500 MYURLHERE（内部服务器错误）”。
我可以在这上面看一双新眼睛指向正确的方向吗？我必须在某个地方出错...

我的复选框/输入（index.html.erb）
<%= check_box_tag 'todo[completed]', todo.id, todo.completed, data: { remote: true, url: url_for(controller: :todos, id: todo.id, action: :completed), method: "POST" }, id: todo.id %>

我的控制器
def completed
if @todo.update_attributes(:completed => params[:completed])
flash[:success] = "Wowzers."
else
flash[:error] = "Not so wowzers.."
end
end
我的路线
resources :todos do
member do
post 'completed'
end
end
非常感谢任何信息。
答案 0 :(得分：1)
如错误所示，您的视图文件夹中没有todos/create.html模板。
默认情况下，控制器操作将在与控制器资源名称匹配的文件夹中呈现相同名称的模板（复数）。我想你想要做的是在你的create行动中适当地渲染/重定向：
def completed
if @todo.update_attributes(:completed => params[:completed])
flash[:success] = "Wowzers."
redirect_to action: :show # Redirect to the #show action so we can show our updated TODO.
else
flash.now[:error] = "Not so wowzers.." # Since we're not redirecting, we use `flash.now` instead of flash.
render :new # Rerender the form because we have an error
end
end
