来自Rails form_for的params hash的自定义名称 [英] Custom name for params hash from Rails form_for
问题描述
通常,使用form_for(@foo)
表示在表单操作的后端,您将在params[:foo]
中保存表单数据,但就我而言,我想将自定义名称空间应用于这些参数,即params[:bar]
,而不是params[:foo]
.
Ordinarily, using form_for(@foo)
means that on the back end of the form's action, you'll have the form data in params[:foo]
, but in my case I'd like to have a custom namespace applied to these params, i.e. params[:bar]
, not params[:foo]
.
我不是在说要通过向form_for
方法提供:namespace
参数来延长名称空间.相反,我的当前名称过长,我想将其缩写.更重要的是,我实际上是在交换新模型来代替现有模型,因此控制器填充了对params[:quoter]
的调用,而我们的新模型提供了params[:company_quoter_intf_quoter]
.有什么想法吗?
I'm not talking about making the namespace longer by supplying the :namespace
argument to the form_for
method. To the contrary, my current name is overlong, and I want to shorten it. More importantly, I'm actually swapping a new model in place of an existing one, so the controller is filled with calls to params[:quoter]
, whereas our new model supplies params[:company_quoter_intf_quoter]
. Any ideas?
