Question

我有这段代码：

<%= simple_form_for(@uniform) do |f| %>
    <%= f.error_notification %>
    <%= f.association :employee, as: :hidden, selected: @employee %>
    <%= f.association :piece %>
    <%= f.button :submit, "Add new piece" %>
<% end %>

但是，隐藏的字段＆＃34;：员工＆＃34;，不发送所选择的员工，只有在这个＆＃34; f.association＆＃34;没有隐藏。

我的控制器是默认支架：

def create
    @uniform = Uniform.new(uniform_params)

    respond_to do |format|
        if @uniform.save
            format.html { redirect_to @uniform, notice: 'Uniform was successfully created.' }
        else
            format.html { render action: 'new' }
        end
    end
end

我需要发送＆＃34; f.association：employee＆＃34;的这个值。但没有在浏览器中显示。

Answer 1

只需发送@employee.id即可？

喜欢这样

<%= f.input :employee_id, as: :hidden %>

您可以立即在控制器中设置值，例如

def new
  @uniform = Uniform.new
  @uniform.employee = @employee
  ...

rails 4 simple_form as：hidden don＆t tt send
