Ruby on rails 以嵌套形式更新多个到多个关联

关于这个问题，我有三个模型。使用

wicked

gem进行多步骤注册

使用者 到

AfterSignup#update

def update
  @user = current_user
  @user.update_attributes(user_params)
  render_wizard @user
end

我相信rails通过命名来处理关联的更新。但可能我弄错了，需要显式更新控制器中的关联。或者也许我没有正确命名物品

不管怎样，我都有点不清楚为什么个人资料没有更新

更新 当我尝试执行更新时，控制台会记录

Unpermitted parameters:：speciality\u id

<%= simple_form_for @user, url: wizard_path do |f| %>

  ...

  <%= simple_fields_for :profile_attributes do |cf| %>

    <%= cf.input :specialty_ids, collection: Role.order(:name), as: :grouped_select, group_method: :specialties, input_html: {multiple: true} %>

  <% end %>

  ...

<% end %>

我有这样定义的强参数

def user_params
  params.permit profile_attributes: [..., :specialty_ids]
end

您的强参数需要一个数组，因此您需要：

def user_params
  params.permit profile_attributes: [..., specialty_ids: []]
end

整个控制台消息是什么，其中包含重要信息。您试图传递的参数在控制台中是什么样子的？params需要一个id数组吗？@Beartech我已经添加了完整的消息

params[：speciality\u IDs]

是一个数组。请尝试

params.permit profile_attributes:[…，speciality_id:[]]

params.permit profile\u attributes:[…，speciality\u id:[]]

ah，就在这里。比我想象的要简单得多。Params有时会让人痛苦。啊，就是这样。比我想象的要简单得多。Params有时会让人痛苦。
