HABTM与Strong Parameters的关联未将用户保存在Rails 4中 [英] HABTM association with Strong Parameters is not saving user in Rails 4

问题描述

用户模型:

has_and_belongs_to_many :events

事件模型:

has_and_belongs_to_many :users

用户控制器:

params.require(:user).permit(:role, {:event_ids => []})

事件控制器:

params.require(:event).permit(:subject, :location, :date, :time, :all_day, :reminder, :notes, {:users_ids => []})

我的表单:

<%= simple_form_for(@event) do |f| %>
    <%= f.input :subject %>
    <%= f.input :location %>
    <%= f.input :date %>
    <%= f.input :time %>
    <%= f.association :users %>
    <%= f.input :all_day %>
    <%= f.input :reminder %>
    <%= f.input :notes %>

    <%= f.button :submit, :class =>"btn btn-default" %>
<% end %>

我希望能够从列表中选择一个用户并将该用户保存到数据库中.但是，当我尝试创建一个新事件时，我在控制台中收到以下消息:

I want to be able to choose a user from a list and save that user to the database. But I am getting the following message in my console when I try to create a new Event:

Unpermitted parameters: user_ids

我的设置是否不正确?我没有将正确的实例变量传递给表单吗?

Do I have my setup incorrect? Am I not passing in the correct instance variables to the form?

推荐答案

U ...详细信息！

Ugh...details details!

以前如何:

params.require(:event).permit(:subject, :location, :date, :time, :all_day, :reminder, :notes, {:users_ids => []})

应该如何:

params.require(:event).permit(:subject, :location, :date, :time, :all_day, :reminder, :notes, {:user_ids => []})

请注意，:users_ids实际上应该是:user_ids！

Notice that :users_ids should actually be :user_ids!
