提交表单时无法将参数传递给控制器​​

Question

在Rails 2.3.8中，我有一个需要customer_id的信用卡控制器。我使用before_filter和一个方法来获取客户ID。我使用像new_admin_credit_card_path（：customer_id => @ customer.id）的路径到达信用卡控制器处理的页面。我在提交创建或修改信用卡表单时遇到问题。客户ID要么没有通过或没有通过，但行动没有正确回应。这里就是我想在我的form_for：

<% form_for :credit_card, 
:url => admin_credit_cards_path(:customer_id => @customer.id) do |f| %> 

    ...BLAH BLAH CODE BLAH... 

    <%= f.submit %> 

<% end %> 

这里的错误，我得到：

路由错误 admin_credit_card_url未能从{产生：CUSTOMER_ID => 37165，：控制器=>“管理/ credit_cards “：：action =>”show“}，expected：{：controller =>”admin/credit_cards“，：action =>”show“}，diff：{：customer_id => 37165}

我也试试这个：

<% form_for (:credit_card, @credit_card, :url => { :controller => "admin/credit_cards", 
:action => "update" }) do |f| %> 

我也得到

未知的动作

没有行动回应37762.

它认为客户ID是行动。

这里是我创建并在控制器更新方法：

def create 
    @credit_card = scope.new(params[:credit_card]) 
    set_modified @credit_card 

respond_to do |format| 
    if @credit_card.save 
    flash[:notice] = 'CreditCard was successfully created.' 
    format.html { redirect_to admin_credit_card_path(:customer_id => @customer.id) } 
    format.xml { head :created, :location => admin_credit_card_url(:customer_id =>  
@customer.id) } 
    else 
    format.html { render :action => "new" } 
    format.xml { render :xml => @credit_card.errors.to_xml } 
    end 
    end 
end 


def update 
@credit_card = scope.find(params[:id]) 
set_modified @credit_card 

respond_to do |format| 
    if @credit_card.save 
    flash[:notice] = 'CreditCard was successfully updated.' 
    format.html { redirect_to admin_credit_card_path(:customer_id => @customer.id) } 
    format.xml { head :ok } 
    else 
    format.html { render :action => "edit" } 
    format.xml { render :xml => @credit_card.errors.to_xml } 
    end 
    end 
end

您应该通过CUSTOMER_ID作为隐藏字段的形式，而不是作为路径助手的一部分。
