允许set_locale使用strong_parameters gem&设计

我在使用设计的小项目中使用strong parameters gem

我添加了User.rb一个locale列。这是我的controllers/users/registrations_controller.rb文件:

class Users::RegistrationsController < Devise::RegistrationsController
  def resource_params
    params.require(:user).permit(:username, :email, :password, :password_confirmation, :locale)
  end
  private :resource_params
  def create
   #add params[:locale] to resource.locale here
   super
  end
end

这些是从表格中收到的参数:

Parameters: {"authenticity_token"=>"ZyrtToHcwsX3zl2ive93cpYaom6HNGA/jnYcSg7pQUQ=", "user"=>{"username"=>"hyperrjas@hyperrjas.com", "email"=>"email@email.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Create account", "locale"=>"es"}

我想添加user :locale column参数params[:locale]

我该怎么做?

谢谢!

我已修复了从此doc中覆盖create方法的问题:

https://github.com/plataformatec/devise/blob/master/app/controllers/devise/registrations_controller.rb

如果您想使用column or field locale向模型用户添加指定strong parameters gem,则可以在下一个时间添加controllers/users/registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController

  def create
    build_resource
    resource.locale = set_locale #set_locale or where you have stored your own locale
    if resource.save
      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_navigational_format?
        sign_up(resource_name, resource)
        respond_with resource, :location => after_sign_up_path_for(resource)
      else
        set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
        expire_session_data_after_sign_in!
        respond_with resource, :location => after_inactive_sign_up_path_for(resource)
      end
    else
      clean_up_passwords resource
      respond_with resource
    end
  end

  def resource_params
    params.require(:user).permit(:username, :email, :password, :password_confirmation, :locale)
  end

  private :resource_params
end

问候!

选项1

在视图中处理它。

您的观点可能类似于:

<%= form_for :user do |f| %>
  <%= f.username %>
  <%= f.password %>
  <%= # Etc... %>
<% end >
<%= select_tag :locale, options_from_collection_for_select(I18n.config.available_locales, :to_s, :to_s), :selected => user.locale %>

因此,请将其更改为:

<%= form_for :user do |f| %>
  <%= f.collection_select :locale, I18n.config.available_locales, :to_s, :to_s, :selected => user.locale %>
  <%= f.username %>
  <%= f.password %>
  <%= # Etc... %>
<% end >

这样,params对象就会在locale中嵌套user

选项2

选项1的缺点是您的区域设置选择可能位于导航栏中,将其移动到表单中是没有意义的。但是,您可以维护2个字段 - 现有导航栏一个,并在表单中隐藏。

<%= form_for :user do |f| %>
  <%= f.hidden_field :locale, value => user.locale %>
  <%= f.username %>
  <%= f.password %>
  <%= # Etc... %>
<% end >

在提交之前使用Javascript将值从导航栏字段复制到隐藏字段:

$('form').on('submit', function(){
  $("#user_locale").val($("#locale").val());
});

选项3

在设置强参数之前将其复制到控制器中:

class Users::RegistrationsController < Devise::RegistrationsController
  private
    def resource_params  
      params[:user][:locale] = params[:locale]
      params.require(:user).permit(:username, :email, :password, :password_confirmation, :locale)
    end
end

所有这些都是接受答案的更好的替代品,因为它们避免了代码重复。每次要升级设计时,您都不必再次复制和粘贴。
