I am trying to insert a captcha in to my application's registration form. I need place a controller helper method to check whether the captcha is valid. I'm using OmniAuth-identity for my simple authentication, which does not provide a controller method. The user's registration form posts directly to the OmniAuth handler and so can't able to check the this helper method that is
if verify_recaptcha(:model => #post, :message => "Oh! It's error with reCAPTCHA!") && #post.save
# ...
else
# ...
end
Can anyone please help me on this how to place a controller helper method using OmniAuth-identity?
The readme gives a hint on hooking up Omniauth-Identity lifecycle events to controller actions. Here's an example adapted to fit what your asking for:
# application.rb
use OmniAuth::Builder do
provider :identity,
:fields => [:email],
:on_login => UsersController.action(:login)
end
this pr will be helpful.
for example:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :identity, on_validation: lambda {|env| Captcha.valid_captcha?(env)}
end

Thru the Shopify API I can create webhooks great. I've created ones that point to RequestBin just fine, the data that is sent to RequestBin is perfect. But when I turn it towards my own controllers nothing happens. I have a binding.pry in my controller to catch anything that comes in, and nothing ever comes in. Not sure why??
Here is me creating the hook with the ShopifyAPI gem:
webhook = ShopifyAPI::Webhook.create(:topic => "carts/update",
:format => "json",:address => "https://dyno-shipping-trimakas.c9users.io
/webhook/cart_callback/")
And then here it is verified when I list the webhooks:
{"id"=>226014599,
"address"=>
"https://dyno-shipping-trimakas.c9users.io/webhook/cart_callback/",
"topic"=>"carts/create",
"created_at"=>"2016-02-24T17:20:02-05:00",
"updated_at"=>"2016-02-24T17:20:02-05:00",
"format"=>"json",
"fields"=>[],
"metafield_namespaces"=>[]}
This is my controller:
class WebHookController < ApplicationController
skip_before_action :verify_authenticity_token, only: [:cart_callback]
def cart_callback
binding.pry
x = params
pp x
end
end
Then finally this is my route:
scope '/webhook', :controller => :webhook do
post :cart_callback
end
Not sure where I went astray??
I am trying to write a custom route that will point to a custom controller action in devise.
I have the setup below right now.
# custom controller
class Registrations::RegistrationsController < Devise::RegistrationsController
layout 'settings'
# GET /resource/edit
def edit
super
end
end
# routing setup
Rails.application.routes.draw do
devise_for :users, controllers: { registrations: "registrations/registrations" },
path_names: { edit: 'profile' }
end
This allows me to have a custom URL localhost:4000/users/profile with no problems.
My question is how can I customize this further to be
localhost:4000/profile
localhost:4000/settings/profile
Note I know that I can set path: '' or path: 'settings', but that will affect all routes within users.
Is there a way that I could have
localhost:4000/settings/profile and localhost:4000/login at the same time using devise_for?
I am not sure how to control these affects separately.
As we can see here, we can use Rails scopes and specify a controller for 'registration', for example. Something like this:
scope :settings do
devise_scope :user do
get '/profile' => 'devise/registrations#edit'
end
end
Devise (2.1) was using my custom views fine until I told it to use a custom controller. Now it ignores my custom views.
Previously everything worked fine:
Tell Devise to use custom views in /config/devise.rb
# ==> Scopes configuration
# Turn scoped views on. Before rendering "sessions/new", it will first check for
# "users/sessions/new". It's turned off by default because it's slower if you
# are using only default views.
config.scoped_views = true
Add custom view: /app/views/subscribers/session/new.html.erb
Set up routes in /config/routes.rb
devise_for :subscribers
Then I added a custom SubscriberSessionsController as /app/controllers/subscriber_session_controller.rb
class SubscriberSessionsController < Devise::SessionsController
before_filter :isInIframe
private
def isInIframe
#hide_navbar = session[:in_iframe]
end
end
And modified /config/routes.rb to tell Devise to use this new controller instead of its default:
devise_for :subscribers, :controllers => {
:sessions => "subscriber_sessions"
}
Once I restart my server, Devise now uses this controller but ignores my custom view.
As is so often the case, ten minutes after posting the question I cracked it.
The reason Devise wasn't finding the view was it was looking for it in a different folder.My replacement controller was called subscriber_sessions.rbso devise was no longer looking in views/subscribers/sessions but views/subscribers/subscriber_sessions.
I solved this problem with the following:
Changed my subscriber routes to:
devise_for :subscribers, :controllers => {
:sessions => "subscribers/sessions"
}
Renamed my subscriber_sessions controller to just sessions and moved it into a subscribers folder so its new name & location are: app/controllers/subscribers/sessions_controller.rb
I also had to add a namespace to the class so the new sessions_controller.rb file looks like this"
class Subscribers::SessionsController < Devise::SessionsController
before_filter :isInIframe
private
def isInIframe
#hide_navbar = session[:in_iframe]
end
end
Hey there, im a little bit confused about handling invalid user authentication request, at login controller. So, i already have modified login view, but cant figure out where to put the exception handling block. It should work like this: you login - if its incorrect you will see warning message at /login .
Any ideas ?
What strategy have you chosen ? In my custom Strategy, I call the class method 'authenticate' on my User class:
class User
def self.authenticate(login, password)
u = User.first(:conditions => ['email = ?', login]) # find a user with this login
if u && u.authenticated?
return u
else
nil
end
end
end
Also, you might want to look at the source code of merb-auth-more/mixins/salted_user which is a module that is automatically mixed into your User class.
you would put your exception handling action in the exceptions controller
# handle NotAuthorized exceptions (403)
def not_authorized
render :format => :html
end
and to customise the view you would create a template in app/views/exceptions/not_authorized.html.haml
I'm trying to run some code on a controller in Volt, but only on certain pages. I've looked through the docs, but I'm not really sure how to get access to a given page's URL. Is there perhaps some hidden variable or something in the page model, like so?:
module Main
class MyController < Volt::ModelController
model :page
def index
end
def template_page
if page.url == "/foo/bar" # obviously, this doesn't actually work
# run some code
end
end
end
end
If you are using bindings in your URL, for example
client '/examples/{{ category }}/{{ example }}', controller: 'examples', action: 'template'
you can access those in the controller via the params collection:
params._category
params._example
In other cases you URL should be static anyway.
Sorry for the late reply. I added docs for the url method which is available from controllers:
