Too Few Arguments
提问by Noah Clark
I am trying to get some Javascript working in my Rails app.
我正在尝试在我的 Rails 应用程序中运行一些 Javascript。
I want to have my index page allow me to edit individual items on the index page, and then reload the index page upon edit.
我想让我的索引页允许我编辑索引页上的单个项目，然后在编辑时重新加载索引页。
My index.html.erb page looks like:
我的 index.html.erb 页面如下所示：
<div id="index">
<%= render 'index' %>
</div>
In my index.js.erb I have:
在我的 index.js.erb 我有：
$('#index').html("<%=j render 'index' %>");
and in my holders_controller:
在我的 holder_controller 中：
def edit
holder = Holder.find(params[:id])
end
def update
@holder = Holder.find(params[:id])
if @holder.update_attributes(params[:holder])
format.html { redirect_to holders_path } #, flash[:success] = "holder updated")
## ^---Line 28 in error
format.js
else
render 'edit'
end
end
When I load the index page it is fine. As soon as click the edit button and it submits the form, I get the following:
当我加载索引页面时，它很好。单击编辑按钮并提交表单后，我会得到以下信息：
But if I go back and refresh the index page, the edits are saved. What am I doing wrong?
但是如果我返回并刷新索引页面，则编辑会被保存。我究竟做错了什么？

You forgot to write responds_toblock:
你忘了写responds_to块：
def update
@holder = Holder.find(params[:id])
if @holder.update_attributes(params[:holder])
respond_to do |format|
format.html { redirect_to holders_path } #, flash[:success] = "holder updated")
format.js
end
else
render 'edit'
end
end
But I am suspicious about your index.html.erb, I don't think that will really work the way you think.
但是我对您的 index.html.erb 表示怀疑，我认为这不会像您认为的那样真正起作用。
