Question

我遇到的问题是，订单的按钮在通过status语句时不会根据它的elsif整数更改它的值。这是我的elsif

    <%if o.status = 1%>
        <button class="btn btn-success"><%= link_to "Accept", accept_path(id: o.id) %> </button><!-- method: :post Accept-->
    <%elsif o.status = 2 %>
        <button class="btn btn-success">"COMPLETED" </button><!--Working-->
    <%elsif o.status = 3%>
        <button class="btn btn-success">Completed </button><!--Review-->
    <%elsif o.status = 4%>
        <button class="btn btn-success">Confirm</button><!--Confirmed-->
    <%elsif o.status = 5%>
        <button class="btn btn-success">PAID</button><!--Paid-->
    <%else%>
        <button class="btn btn-success">Contact for Issues</button> <!--Contact-->
    <%end%>

目前按钮显示“Accept”/ Status：1值，无论订单的状态整数值是什么。

在为我的索引提供obj时，我使用

@orders = Order.where(user_id: nil)
@orders_user = current_user.orders

这些部分呈现为<%= render 'order', obj: @orders_user%>

我不知道为什么这不起作用但是当我将第一个if语句发送到nil而不是1时，按钮会立即显示“已完成”，这是status = 2

我如何分配状态，但.save?部分也出现了错误，但我稍后会修复此问题，但这也可能是问题所在。

   def create
       @order = Order.where(order_params).first_or_create
       @order.status = 1
    if @order.save?
        flash[:success] = "Order was successfully made"
        redirect_to root_path
    else
        #flash error
        render 'new'
   end
  end

尝试在视图中创建订单的日志是undefined method save？'为＃你的意思？保存保存！`但在控制台中日志是

将=更改为== 您将1分配给o.status而不是比较。

  <%if o.status == 1%>
    <button class="btn btn-success"><%= link_to "Accept", accept_path(id: o.id) %> </button><!-- method: :post Accept-->
<%elsif o.status == 2 %>
    <button class="btn btn-success">"COMPLETED" </button><!--Working-->
<%elsif o.status == 3%>
    <button class="btn btn-success">Completed </button><!--Review-->
<%elsif o.status == 4%>
    <button class="btn btn-success">Confirm</button><!--Confirmed-->
<%elsif o.status == 5%>
    <button class="btn btn-success">PAID</button><!--Paid-->
<%else%>
    <button class="btn btn-success">Contact for Issues</button> <!--Contact-->
<%end%>

订单上的状态部分未反映在使用elsif的按钮输出中
