Ruby on rails 创建多个：通过记录时跳过验证

在my db中，有很多用户的数据无效（没有手机号码）。因为我刚才添加了移动状态验证。当我尝试添加新事件时，会收到错误消息“Users mobile number必须为…格式”。创建事件时如何跳过用户验证

event.rb

class Event < ActiveRecord::Base
  has_many :participations
  has_many :users, :through => :participations
end

class User < ActiveRecord::Base
  has_many :participations
  has_many :events, :through => :participations
end

 def create
    @event = Event.new(event_params)

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

 <%= form_for @event, :html => {:class => 'row'} do |f| %>
      <%= f.error_messages %>

      <%= f.label :name %>
      <%= f.text_field :name %>

      <%= f.label :user_ids, "Participants" %>
      <%= f.collection_select :user_ids, User.all, :id, :name, {}, { :multiple => true } %>

      <%= clear %>

      <%= f.submit 'Save' %>
    <% end %>

\u form.html.erb

class Event < ActiveRecord::Base
  has_many :participations
  has_many :users, :through => :participations
end

class User < ActiveRecord::Base
  has_many :participations
  has_many :events, :through => :participations
end

 def create
    @event = Event.new(event_params)

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

 <%= form_for @event, :html => {:class => 'row'} do |f| %>
      <%= f.error_messages %>

      <%= f.label :name %>
      <%= f.text_field :name %>

      <%= f.label :user_ids, "Participants" %>
      <%= f.collection_select :user_ids, User.all, :id, :name, {}, { :multiple => true } %>

      <%= clear %>

      <%= f.submit 'Save' %>
    <% end %>

{:class=>'row'}do | f |%>
真}%>

Set

validate:false

在事件

有多个：用户关联时

class Event < ActiveRecord::Base
  has_many :participations
  has_many :users, :through => :participations, validate: false
end

class事件:participations，验证：false
结束
我想知道如何在Rails 5.0.0.RC1中实现这一点。谢谢。创建父记录并分配子id（如
Event.create（用户id:[1,2,3]）
Rails在每个用户上运行
valid？
，而不分配
Event\u id
）。因此，您无法检测事件id是否已更改并跳过验证：（.非常感谢，这个答案对我非常有帮助。
