redirect_to与轨道参数

Question

我有一个子域的应用程序。当用户登录到根域时。我想将他/她重定向到他/她的公司子域。我正在使用设计。

这是我迄今为止

def create 
    subdomain = request.subdomain 
    user = User.find_by_email(params[:user][:email]) 
    if subdomain.present? 
    resource = warden.authenticate!(auth_options) 
    set_flash_message(:notice, :signed_in) if is_navigational_format? 
    sign_in(resource_name, resource) 
    redirect_to statistics_url 
    else 
    redirect_to sign_in_at_subdomain_url(:subdomain => user.firm.subdomain), :params => params 
    end 
end 

def sign_in_at_subdomain 
    resource = warden.authenticate!(auth_options) 
    set_flash_message(:notice, :signed_in) if is_navigational_format? 
    sign_in(resource_name, resource) 
    redirect_to statistics_url 
end 

当用户登录低谷登录表单，则params被发送到创建动作，即设计用于验证身份。正如你在我的代码中看到的那样，当一个子域出现时，登录工作得很好，但是当它不存在时，我想要重定向到子域和sign_in_at_subdomain。

如何将parmas表单通过创建操作传递给sign_in_at_subdomain操作？

您可以使用after_sign_in_path_for从根romain登录用户并将其签入他所属的子域。以下是来自example Rails 3 app with basecamp like subdomains and authentication（使用Devise）。

def after_sign_in_path_for(resource_or_scope) 
    scope = Devise::Mapping.find_scope!(resource_or_scope) 
    subdomain_name = current_user.subdomain.name 
    if current_subdomain.nil? 
    # logout of root domain and login by token to subdomain 
    token = Devise.friendly_token 
    current_user.loginable_token = token 
    current_user.save 
    sign_out(current_user) 
    flash[:notice] = nil 
    home_path = valid_user_url(token, :subdomain => subdomain_name) 
    return home_path 
    else 
    if subdomain_name != current_subdomain.name 
     # user not part of current_subdomain 
     sign_out(current_user) 
     flash[:notice] = nil 
     flash[:alert] = "Sorry, invalid user or password for subdomain" 
    end 
    end 
    super 
end
