Devise Rails 3.2.22 remember_user_token not set

Question

我试图用devise 3.5.2和rails 3.2.22来管理一些奇怪的问题。

问题是devise没有设置remember_user_token cookie。 我的应用程序是一个API，所以我有sessions_controller重写。

def create 
    # build_resource 
    resource = User.find_for_database_authentication(email: params[:email]) 
    return invalid_login_attempt(email: t('api.errors.email.user_not_exists', email: params[:email])) unless resource 

    unless resource.active_for_authentication? 
    render json: { success: false }.merge(errors: t('api.errors.email.inactive')), status: :ok 
    return 
    end 

    if resource.is_deleted 
    render json: { success: false }.merge(errors: t('api.errors.email.deleted')), status: :ok 
    return 
    end 

    if resource.valid_password?(params[:password]) 
    sign_in("user", resource) 
    resource.enable_beta unless resource.beta_enabled? 
    render json: { success: true }.merge(user: resource.as_json(user: resource)), status: :ok 
    return 
    end 
    invalid_login_attempt(password: t('api.errors.email.wrong_password')) 
end 

这里是我的用户模型（设计部分）

# Extensions 
devise :database_authenticatable, :registerable, :confirmable, 
    :recoverable, :rememberable, :trackable, :validatable, :lastseenable 

登录工作就像一个魅力，但reme​​mber_user_token饼干未设置。

Completed 200 OK in 2515.4ms (Views: 8.7ms | ActiveRecord: 4.4ms | Sphinx: 0.0ms) 

我也试图用手来设置cookie的：

cookies["remember_user_token"] = { 
    value: user.class.serialize_into_cookie(user.reload), 
    expires: 3.year.from_now, 
    domain: RAILS_DOMAIN 
    } 

，但没有运气了。似乎有些东西可以防止cookie设置。你能分享你的想法吗？

在此先感谢。

答案是致命的简单，在GitHub上的设计源代码解释

module Devise 
    module Controllers 
    # A module that may be optionally included in a controller in order 
    # to provide remember me behavior. Useful when signing in is done 
    # through a callback, like in OmniAuth. 

所以，我需要做的是包括适当的模块，在我的控制器，并添加方法两行

module API::V1 
    class SessionsController < Devise::SessionsController 
    include Devise::Controllers::Rememberable 
    prepend_before_filter :require_no_authentication, only: [:create] 

    include Corsable 

    ... 

    def create 
    # build_resource 
    resource = User.find_for_database_authentication(email: params[:email]) 
    return invalid_login_attempt(email: t('api.errors.email.user_not_exists', email: params[:email])) unless resource 

    unless resource.active_for_authentication? 
     render json: { success: false }.merge(errors: t('api.errors.email.inactive')), status: :ok 
     return 
    end 

    if resource.is_deleted 
     render json: { success: false }.merge(errors: t('api.errors.email.deleted')), status: :ok 
     return 
    end 

    if resource.valid_password?(params[:password]) 
     sign_in(resource) 
     remember_me(resource) if params["remember_me"].present? 
     resource.enable_beta unless resource.beta_enabled? 
     render json: { success: true }.merge(user: resource.as_json(user: resource)), status: :ok 
     return 
    end 
    invalid_login_attempt(password: t('api.errors.email.wrong_password')) 
    end 

    def destroy 
    forget_me(current_user) 
    sign_out(resource_name) 
    respond_to do |format| 
     format.json { render json: '', status: :no_content } 
    end 
    end 
end
