Question

我无法从数据库中删除记录。我一直收到这个错误。

PG::Error: ERROR: zero-length delimited identifier at or near """" LINE 1: ...ctive_items" WHERE "users_items"."" = $1 ^ : DELETE FROM "users_items" WHERE "users_items"."" = $1

这是方法。

def delete_items
    @destroyer = UsersItems.find_by_item_id(params[:items_id])
    @destroyer.destroy
    flash[:notice] = "Item deleted"
    redirect_to itemsearch_path

端

<a><%= link_to "Delete Item",{:controller => "items", :action => "delete_items",:method => :delete,:item_id => item.id}%></a>

Answer 1

改变这个：

<a><%= link_to "Delete Item",{:controller => "items", :action => "delete_items",:method => :delete,:item_id => item.id}%></a>

为此：

<%= link_to "Delete Item",{:controller => "items", :action => "delete_items", :item_id => item.id}, :method => :delete%>

当我尝试从数据库中删除单个记录时，为什么会一直出错？轨道
