[英]Rails devise if session sign_in error, then redirect to some page (back)
How can i change standart devise session_controller, so that if, for example i entered incorrect password i'm redirected :back (is not required), and see my error's... 我该如何更改standart devise session_controller,以便例如,如果我输入了错误的密码,我将被重定向:back(不是必需的),并查看我的错误...
For what i need this? 我需要这个吗? Becouse i have my login only in template which is rendered in layout left block on all pages, and i didn't have new action-view...
因为我只有在模板中登录,该模板在所有页面的布局左图块中呈现,所以我没有新的动作视图...
So how to do error's redirect to other page with validation message errors... ? 那么如何将错误重定向到带有验证消息错误的其他页面...?
Here is standart session_controller (now i didn't create it one, it is "nested"): 这是标准的session_controller(现在我没有创建它,它是“嵌套的”):
class Devise::SessionsController < DeviseController
prepend_before_filter :require_no_authentication, :only => [ :new, :create ]
prepend_before_filter :allow_params_authentication!, :only => :create
prepend_before_filter { request.env["devise.skip_timeout"] = true }
# GET /resource/sign_in
def new
self.resource = build_resource(nil, :unsafe => true)
clean_up_passwords(resource)
respond_with(resource, serialize_options(resource))
end
# POST /resource/sign_in
def create
self.resource = warden.authenticate!(auth_options)
set_flash_message(:notice, :signed_in) if is_navigational_format?
sign_in(resource_name, resource)
respond_with resource, :location => after_sign_in_path_for(resource)
end
# DELETE /resource/sign_out
def destroy
redirect_path = after_sign_out_path_for(resource_name)
signed_out = (Devise.sign_out_all_scopes ? sign_out : sign_out(resource_name))
set_flash_message :notice, :signed_out if signed_out && is_navigational_format?
# We actually need to hardcode this as Rails default responder doesn't
# support returning empty response on GET request
respond_to do |format|
format.all { head :no_content }
format.any(*navigational_formats) { redirect_to redirect_path }
end
end
protected
def serialize_options(resource)
methods = resource_class.authentication_keys.dup
methods = methods.keys if methods.is_a?(Hash)
methods << :password if resource.respond_to?(:password)
{ :methods => methods, :only => [:password] }
end
def auth_options
{ :scope => resource_name, :recall => "#{controller_path}#new" }
end
end
also method in appcontroller appcontroller中的方法
def after_sign_in_path_for(resource)
case resource
when User then
user = User.find(current_user.id)
total_markup_for_user = user.groups.map(&:markup).sum
if current_cart.present?
cart_id = current_cart.id
else
cart_id = nil
end
***
end
if request.referrer.to_s.include? "users"
root_path
else
request.referrer
end
when Admin::Admin then :admin_mainpage
end
end
Devise has documentation that shows you how to override their default redirects here: Devise的文档向您展示了如何在此处覆盖其默认重定向:
https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in
Basically you would go into your application_controller.rb and for example write something like this 基本上,您将进入您的application_controller.rb并例如编写如下内容
def after_sign_in_path_for(resource)
request.env['omniauth.origin'] || stored_location_for(resource) || new_survey_path
end
def after_sign_out_path_for(resource_or_scope)
root_path
end
end 结束
hope it helps 希望能帮助到你
Try something like this, add a new respond_with in case sign_in returns false. 尝试类似这样的操作,添加一个新的response_with,以防sign_in返回false。
def create
self.resource = warden.authenticate!(auth_options)
set_flash_message(:notice, :signed_in) if is_navigational_format?
if sign_in(resource_name, resource)
respond_with resource, location: after_sign_in_path_for(resource)
else
respond_with resource, location: root_path
end
end
