当调用销毁记录不被从数据库中删除 [英] When calling destroy, record is not being removed from DB

问题描述

我有打算摧毁一个记录中的link_to：

I've got a link_to meant to destroy a record:

<%= link_to 'Delete from DB', {:controller => 'foos', :action => 'destroy', :id => foo.id}, :class => "btn btn-primary btn-mini" %>

在控制器中的破坏方法：

The destroy method in the controller:

  def destroy
    @foo = Foo.find(params[:id])
    @foo.destroy

  respond_to do |format|
    format.html { redirect_to :back }
    format.json { head :no_content }
  end
end

pressing按钮不会删除的记录，但如果我打开轨控制台和呼叫 .destroy 在现有FOO，它是从拆除DB。

Pressing the button doesn't delete the record, but if I open up rails console and call .destroy on an existing foo, it is removed from the DB.

让我知道，如果你在这里看到一个错误。谢谢你。

Let me know if you see a mistake here. Thanks.

推荐答案

这可能是因为您发送 GET 的要求，而你需要发送删除，以便调用破坏操作请求。所以，你的链接应该是：

It's probably because you send GET request while you need to sent DELETE request in order to call destroy action. So, your link should look:

<%= link_to 'Delete from DB', foo, :class => "btn btn-primary btn-mini", :method => 'delete' %>
