Invite new user to website per e-mail - ruby-on-rails

I would like to build a form on my website where users, who are already registered, could invite new users via e-mail to sign up for this website. The user who sent the invitation and the user who accepted the invitation (and signed up) are then connected through a "friendship" relationship.
I would like to send the invitations via the ActionMailer.
My problem is: How do I "link" the email to the friendship-relationship. One way is probably to create a unique sender_id, which points to the user and which will be used as a link in the email.
Is there another possibility?
Thanks for your help!

In the link create an argument, where you can pass an ID that could identify your relationship.
Something like: http://example.com/invite?abcd
Than in you controller you can treat the relationship.
Other option is to use Devise Invitable

How do I resend invitation to a user using devise invitable?

I have devise invitable gem
Hooked up in my app as well as devise.
Everything working fine. When I create new user, they are saved in database and mailer sends email an email address. User clicks on email, sets password and then is logged in.
But sometimes these users lose their email or rather can’t find it in their email inbox. I’d like to have a resend invite button on the users index page.
When user clicks resend, I want the invites user to get another email sent to them.
Had anyone successfully accomplished this with devise invitable? If so, can you share how?
The gem adds a resend_invitation configuration parameter on your invitable-enabled model. From the docs:
resend_invitation: resend invitation if user with invited status is invited again. Enabled by default.
So, calling .invite! again on a record that's marked as invited will do the trick for you.

Is it possible for users to contact each other without knowing their email addresses via Mandrill?

My website allow User A send email to User B through a form. Currently if User B want to reply, he need to login to my website and use the same form.
User A dont know the User B's email address and vice versa.
I would like to allow User B reply to User A directly using his mail client without need to login to my website (while still keep both email addresses confidentially). So User A send a message to User B using the form. User B can reply to user A using his email client, and user B can reply to user A using email client too without reveal their email address.
I was told this is possible with Mandrill Webhook. Is that correct? Can anybody please show me how?
Thanks a lot.
I think what you need to do is inbound email processing.
First, create an inbound domain in your Mandrill dashboard.
Set up routes / webhooks in your dashboard (for example, sending an email to pm#example.com will send a POST to http://example.com/email-processing/pm).
In your application, process the received message and decide if you have to send it to one of your user, and more important, which user.
To do so, you can add a unique ID inside your emails. So you just have to read this ID when you receive an email, and you know who is the sender and who should be the receiver. Of course, you should also check the sender's email address.

Devise email custom 'from' parameter based on logged in user

I have an app in which companies can add customers. Each company has its own email.
Currently, when a new customer is created, they receive devise emails (confirmation, password reset etc.) through our domain email, but I want to the customers to see the email as being sent from the one specified by the company instead.
How can I intercept these emails and set the from parameter?
Read this article. It describe how to create custom mailer for Devise.
Inside of your custom mailer you can assign appropriate values to from field.

Does devise work with multiple email_id with same account ??

Devise is a fantastic gem available for basic or omniauth authentication sign_up and other things like sessions maintenance, resend confirmation password etc .
But is it possible using devise to map multiple email addresses to same user ?
Like I have 3,4 email ids such as
sahil#abc.com
sahil#xyz.com
sahil#mno.com
Use Case and Example
I have already registered with my first email id i.e. sahil#abc.com using an automated system and account is created. But i always prefer to use my other email_id i.e. sahil#xyz.com. So, i want to build a system where user can login using any one of the above email adresses with the same/different password. But there should be one single account for the user.
I'd say:
you've one email field
you have other emails stored somewhere
You could tell Devise that you allow login based on different fields.
I think the cooler way is to give a try to override the 'authentication_keys' method, as it allows you to define the keys.
But how ever , following link has a working solution :)
HTH
Here is what i exactly needed RoR Devise: Sign in with username OR email
def self.find_for_database_authentication(conditions={})
(self.find_by_email(conditions[:email])) || (AuthorizedEmail.confirmed.find_by_email(conditions[:email]).user if AuthorizedEmail.confirmed.find_by_email(conditions[:email]).present?)
end
What it does is :
Firstly tries to find the user record for authentication by searching with email id.
If it gets the record it returns the record else we go to next part.
It finds in the authorised emails table if there exists any validated and confirmed email in the table. If there is such an entry, it tries to find the user related to that particular authorised email and returns that.

Send custom confirmation email in Devise depending on role defined in the database

I am using Devise for registration of a site with confirmable. However, I have two different roles for this site. The first role is the "main" role that uses the regular Devise signup procedure. Accounts in a second role are supposed to be created after the original user confirms their account, logs in for the first time and saves a certain model. For example, if a user signs up for the site (as role type 1) the get a confirmation email from Devise as normal. Next, they visit the confirmation link, verify their account and then fill out a form where they specify some friends that should also get accounts. The friends are role type 2 and they should get a different confirmation email than the original person who signed up their friends for the account. The accounts for the friends are created when the form filled out by the original user is saved. In addition, a person can edit and add more friends later so accounts might also need to be created on the update method of the relevant form/object and those new users will need to be sent the correct email. To be clear, I do not want to skip confirmation - I just want to send different confirmation emails to the user depending on their roles. I cannot figure out how to handle this properly. If I try to create the friends accounts in code when the form is saved with User.new, calling user.skip_confirmation! will automatically confirm them. However, I do not want anyone automatically confirmed - I just want to select a different customizable confirmation email to send depending on various conditions. Can someone point me in the right direction?
Check out send_on_create_confirmation_instructions method and comments for it in your /gems/devise-x.x.x/lib/devise/models/confirmable.rb
