Question

我有以下Devise注册表（省略了无关标记）：

<%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { id: "payment-form" }) do |f| %>
  <%= f.fields_for resource.paid_account do |pa| %>
    <%= pa.collection_select :account_plan_id, @account_plans, :id, :name_with_price %>
  <% end %>
<% end %>

此表单吐出以下HTML：

<select id="user_paid_account_account_plan_id" name="user[paid_account][account_plan_id]">
  <option value="2">Lite ($10.00/mo)</option>
  <option value="3">Professional ($20.00/mo)</option>
  <option value="4">Plus ($30.00/mo)</option>
</select>

然后，我的ApplicationController：

中包含以下代码

class ApplicationController < ActionController::Base
  before_filter :configure_permitted_parameters, if: :devise_controller?

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(
        :email,
        :password,
        :paid_account => :account_plan_id # <-- THIS IS PROBABLY WRONG
      )
    end
  end
end

当我提交表单时，我得到“PaidAccount（＃2163736620）预期，获得ActionController ::参数（＃2173083140）”。

我也尝试过以下不会出错的内容，但它也没有创建记录：

  u.permit(
    :email,
    :password,
    :paid_account => []
  )

我做错了什么？

显示您的两个模型（我相信User和PaidAccount）会有很大帮助。无论如何，假设User与PaidAccount具有一对一的关系，代码应该如下所示：

class User < ActiveRecord::Base
  has_one :paid_account

  accepts_nested_attributes_for :paid_account
end

class PaidAcount < ActiveRecord::Base
  belongs_to :user
end

class ApplicationController < ActionController::Base
  before_filter :configure_permitted_parameters, if: :devise_controller?

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(
        :email,
        :password,
        :paid_account_attributes => :account_plan_id
      )
    end
  end
end

查看您的日志，了解表单值的提交方式。 StrongPameters gem和Active Record's Nested Attributes的文档也应该有所帮助。
