wicked 多步骤注册的宝石。

用户

class User < ApplicationRecord
  has_one :profile
  has_many :specialties, through: :profile

  accepts_nested_attributes_for :profile, allow_destroy: true
end

简况

class Profile < ApplicationRecord
  belongs_to :user
  has_many :profile_specialties
  has_many :specialties, through: :profile_specialties
end

专业

class Specialty < ApplicationRecord
  has_many :profile_specialties
  has_many :profiles, through: :profile_specialties
end

以我的形式,我通过了 specialty_ids

<%= 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 %>

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不更新。

更新

当我尝试更新时,控制台会记录 Unpermitted parameters: :specialty_ids

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

更新2

这是完整的日志

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
