使用 Devise 从 Turbolinks 升级到 Turbo 后，我得到了 "undefined method `to_model' for true:TrueClass"
I got "undefined method `to_model' for true:TrueClass" after upgrade from Turbolinks to Turbo with Devise
我有这个控制器
# app/controllers/users/sessions_controller
class Users::SessionsController < Devise::SessionsController
before_action :redirect_admin_user, only: [:new]
skip_before_action :verify_authenticity_token, only: [:create]
def destroy
super
end
protected
def redirect_admin_user
if admin_signed_in?
redirect_to root_url, alert: "Please sign out of admin session"
end
end
end
我尝试登录并收到错误 "NoMethodError in Users::SessionsController#create" "undefined method `to_model ' 对于 true:TrueClass" at I18n.with_locale(locale, &action) from this controller
# app/controllers/application_controller
require 'action_text'

资源：
ruby '3.0.2'
rails '~> 6.1', '>= 6.1.4'
rails-i18n '~> 6.0'
设计 '~> 4.7', '>= 4.8'
我通过 coding 在 rails 上学习了 ruby 任何人都可以告诉我如何解决这个错误吗？
问题就在这里：
def after_sign_in_path_for(resource)
dashboard_path
ahoy.authenticate(resource)
end
此方法应该返回一个字符串到您应该重定向用户的位置，ahoy.authenticate而不是 returns 一个布尔值。利用 Devise 控制器的流程的一种不那么骇人听闻的方法是简单地调用 super 块：
# @see https://github.com/rubocop/ruby-style-guide#namespace-definition
module Users
class SessionsController < Devise::SessionsController
before_action :redirect_admin_user, only: [:new]
skip_before_action :verify_authenticity_token, only: [:create]
# note that your destroy method is completely superflouos - just use the super method
def create
# the parent controller yields after successfully signing a user in
super do |resource|
ahoy.authenticate(resource)
end
end
protected
def redirect_admin_user
if admin_signed_in?
redirect_to root_url, alert: "Please sign out of admin session"
end
end
# remove the method in ApplicationController
def after_sign_in_path_for(resource)
dashboard_path
end
end
end
end
这是可行的，因为几乎所有 Devise 控制器都在战略点屈服：
class Devise::SessionsController < DeviseController
# ....
def create
self.resource = warden.authenticate!(auth_options)
set_flash_message!(:notice, :signed_in)
sign_in(resource_name, resource)
yield resource if block_given?
respond_with resource, location: after_sign_in_path_for(resource)
end
# ...
end
它不是很明显，但如果电子邮件或密码无效，sign_in 将抛出异常，因此只有在用户身份验证成功后才能到达 yield resource if block_given?。
我有这个控制器
# app/controllers/users/sessions_controller
class Users::SessionsController < Devise::SessionsController
before_action :redirect_admin_user, only: [:new]
skip_before_action :verify_authenticity_token, only: [:create]
def destroy
super
end
protected
def redirect_admin_user
if admin_signed_in?
redirect_to root_url, alert: "Please sign out of admin session"
end
end
end
我尝试登录并收到错误 "NoMethodError in Users::SessionsController#create" "undefined method `to_model ' 对于 true:TrueClass" at I18n.with_locale(locale, &action) from this controller
# app/controllers/application_controller
require 'action_text'

资源：

rails '~> 6.1', '>= 6.1.4'
rails-i18n '~> 6.0'
设计 '~> 4.7', '>= 4.8'
我通过 coding 在 rails 上学习了 ruby 任何人都可以告诉我如何解决这个错误吗？
问题就在这里：
def after_sign_in_path_for(resource)
dashboard_path
ahoy.authenticate(resource)
end
此方法应该返回一个字符串到您应该重定向用户的位置，ahoy.authenticate而不是 returns 一个布尔值。利用 Devise 控制器的流程的一种不那么骇人听闻的方法是简单地调用 super 块：
# @see https://github.com/rubocop/ruby-style-guide#namespace-definition
module Users
class SessionsController < Devise::SessionsController
before_action :redirect_admin_user, only: [:new]
skip_before_action :verify_authenticity_token, only: [:create]
# note that your destroy method is completely superflouos - just use the super method
def create
# the parent controller yields after successfully signing a user in
super do |resource|
ahoy.authenticate(resource)
end
end
protected
def redirect_admin_user
if admin_signed_in?
redirect_to root_url, alert: "Please sign out of admin session"
end
end
# remove the method in ApplicationController
def after_sign_in_path_for(resource)
dashboard_path
end
end
end
end
这是可行的，因为几乎所有 Devise 控制器都在战略点屈服：
class Devise::SessionsController < DeviseController
# ....
def create
self.resource = warden.authenticate!(auth_options)
set_flash_message!(:notice, :signed_in)
sign_in(resource_name, resource)
yield resource if block_given?
respond_with resource, location: after_sign_in_path_for(resource)
end
# ...
end
它不是很明显，但如果电子邮件或密码无效，sign_in 将抛出异常，因此只有在用户身份验证成功后才能到达 yield resource if block_given?。
