我正在尝试使用Devise创建用户注册表单，该表单还允许创建与该用户关联的新业务。
我有一个商业模式设置，似乎无法将业务信息保存到数据库。下面是我的代码，我对rails很新，所以如果我问一个明显答案的问题我会道歉。
new.html.erb（用户）
<div class="content">
<div class="row">
<div class="col-md-6 col-md-offset-3">
<h1>Sign Up</h1>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="form-group">
<label>Name</label>
<%= f.text_field :username, :autofocus => true, :class => "form-control", :placeholder => "Full Name" %>
</div>
<div class="form-group">
<%= f.label :email %>
<%= f.text_field :email, :class => "form-control", :placeholder => "Email" %>
</div>
<div class="form-group">
<%= f.label :password %>
<%= f.password_field :password, :class => "form-control", :placeholder => "Password" %>
<p class="help-block">Passwords must be a minimum of 8 characters.</p>
</div>
<div class="form-group">
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation, :class => "form-control", :placeholder => "Retype Password" %>
</div>
<!-- Business Infomation -->
<h2>Business Information</h2>
<%= f.fields_for :business do |b| %>
<div class="form-group">
<%= b.label :name %>
<%= b.text_field :name, :class => "form-control", :placeholder => "Business Name" %>
</div>
<div class="form-group">
<%= b.label :address %>
<%= b.text_field :address, :class => "form-control", :placeholder => "Address" %>
</div>
<div class="row">
<div class="col-sm-6">
<div class="form-group">
<%= b.label :city %>
<%= b.text_field :city, :class => "form-control", :placeholder => "City" %>
</div>
</div>
<div class="col-sm-2">
<div class="form-group">
<%= b.label :state %>
<%= b.text_field :state, :class => "form-control", :placeholder => "State" %>
</div>
</div>
<div class="col-sm-4">
<div class="form-group">
<%= b.label :zip %>
<%= b.text_field :zip, :class => "form-control", :placeholder => "ZIP" %>
</div>
</div>
</div>
<div class="form-group">
<%= b.label :country %>
<%= b.text_field :country, :class => "form-control", :placeholder => "Country" %>
</div>
<% end %>
<div class="well">
<%= f.submit "Sign Up", :class => "btn btn-primary" %>
</div>
<% end %>
</div>
</div>

答案 0 :(得分：1)
尝试覆盖Devise的注册控制器：
# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
def create
# save business here
end
end
然后告诉设计使用自定义控制器：
# app/config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}
