Ruby on Rails-gem设计，参数:错误数量的参数(给定0，预期1)

Question

我安装了设计宝石，想在注册页面上添加一些列。

app/controllers/users/registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController
before_action :configure_sign_up_params, only: [:create]

protected
def configure_sign_up_params
devise_parameter_sanitizer.permit(:sign_up){|u| u.permit(:company_id, :name, :email, :profile, :prefecture_id, :address, :password, :password_confirmation)}
end

app/views/devise/registrations/new.html.erb

<%= simple_form_for(resource, as: resource_name, url:registration_path(resource_name)) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.label :campany_id %><br>
<%= f.collection_select :campany_id, Campany.all, :id, :name, include_blank: true %>
<%= f.input :name, required: true, autofocus: true %>
<%= f.inneput :email, paceholder:"メールアドレス", required: true, autofocus: true %>
<%= f.input :profile, required: true, autofocus: true %>
*<%= f.label :prefecture_id %><br>
<%= f.collection_select :prefecture_id, JpPrefecture::Prefecture.all, :code, :name %>
<%= f.input :address, required: true, autofocus: true %>
<%= f.input :password, required: true, hint: ("#{@minimum_password_length} characters minimum" if @minimum_password_length) %>
<%= f.input :password_confirmation, required: true %>
</div>
<div class="form-actions">
<%= f.button :submit, "新規登録" %>
</div>
<% end %>

config/routes.rb

devise_for :users, controllers: { 
registrations: 'users/registrations' 
}

当我填写表格并提交时。它显示"参数：错误的参数数(给定0，预期1("此错误！有一些错误吗？

谢谢！

Answer 1

在new.html.erb中，对于输入电子邮件，您的输入拼写应为 f.input ，您也给出了 Campany_id ，但是在控制器中，您使用了 Company_id 。

和控制器：

def configure_sign_up_params
devise_parameter_sanitizer.permit(:sign_up){|u| u.permit(:company_id, :name, :email, :profile, :prefecture_id, :address)}
end

您只需要允许您添加的参数即可。您不需要允许密码或corkern_password。另外所有允许的参数或形式的参数都必须在您的表中。

希望这会有所帮助。
