我正在尝试使用以下代码删除帖子:
<%= link_to 'Destroy', post, :method => :delete, :onclick => "return confirm('Are you sure you want to delete this post?')" %>
这不起作用......它只是将我重定向回帖子(posts/:id}
但是,如果我使用以下代码,它可以工作
<%= button_to 'Destroy', post, method: :delete, :onclick => "return confirm('Are you sure you want to delete this post?')" %>
在这种情况下是否有可能link_to
表现得button_to
如此?
编辑:销毁控制器功能
def destroy
@post = Post.find(params[:id])
@post.destroy
respond_to do |format|
format.html { redirect_to posts_url }
format.json { head :no_content }
end
end
当我单击销毁按钮时记录:
