Rails ParameterMissing 的最佳位置
Best In Place for Rails ParameterMissing
我无法更新 Best In Place。这是我第一次使用这个 gem 或制作一个 Rails 应用程序,所以我确定我只是遗漏了一些简单的东西,即使我已经在这里搜索了文档并搜索了其他问题.
这是我在控制台中得到的错误:

我的控制器:

# Use callbacks to share common setup or constraints between actions.
def set_task

def task_params
params.require(:task).permit(:title, :description, :priority)

我的部分观点:
<div class="panel panel-default" data-id="<%= task.id %>">
<div class="panel-heading">
<h3 class="panel-title"><span class="rest-in-place" data-url="/tasks/<%= task.id %>" data-object="tasks" data-attribute="title" data-placeholder="Enter a title">
<%= task.title %>
</span></h3>
</div>
<div class="panel-body">
<%= truncate task.description, length: 50 %>
</div>
</div>
我非常感谢能得到的任何帮助。我 99% 确定这是我在控制器中配置错误的东西,我就是一辈子都弄不明白它是什么。
编辑:这样做的背景是我有一堆 'Tasks',我想将它们全部列在索引中,并且只需单击标题就可以更新索引中的任何任务。

这是告诉您没有名称为 :task
的参数。您可以在这条消息上方看到您的参数。
Parameters: {"authenticity_token"=>"cAwRbx8JeYDMG1LrR7nl0VQfwW/x00RUd8rsTP8Iwc
0=", "tasks"=>{"title"=>"Task 1sadsads"}, "id"=>"1"}
您的参数中有 tasks
。此信息来自您的观点。
data-object="tasks"
尝试将您视图中的这部分更改为 task
,它应该会正确发送请求。
