I intend to build a customized logic on Devise on Rails. Here is the logic: user can try to login, and if the does not exist, then it will create the account for the user. Just to skip the registration process.
Now sure how to hack into Devise. Please help!
Thank you in advance!
Edit: Sorry that I didn't make it clear enough: I have implement the on-create-validation on the user model to authenticate with another system. Logic is:
If success with another system's authenticator, then create a new user with the same password and login user.
Else login fail.
You know that if someone make typo he will create new account and will be mad that all of his/her stuff disappeared? When there is small amount of user then it isn't problem. But when your society will grow then it can make you some black-PR. You should rather check by AJAX call that there is user with that email/username/nick and if not then show the registration form, but on other hand this can be security issue if your users are signing in using non-public data like email or if username is different from nickname shown on your page.
Why would you want to skip the registration process? I don't see any benefits.
First, the user can enter the wrong username or password by accident.
Second, the user can enter the right username, but the wrong password. So he/she already is a registered user, but still get a new account.
Third, when a new user is automatically registered, how does the user actually now what his username or more importantly, his password will be?
Personally, why not just add "Remember Me" or "Forgot Password?" to your login form. If, for any reason, the user doesn't want to enter his login data or simply doesn't know his password required to login he can use these options.
Or, if you are working with permissions, why not just make a guest user if someone is not logged in?
What if they type in the wrong password or username on accident? Then you just automatically create them an account? IMO that would be a bad user experience. You either know your account or you don't. If you have an account and can't remember then you use the 'Forgot my ...'. If you don't have an account, then you go signup. You could implement oAuth and use accounts from a multitude of sites (i.e. Github, Twitter, Facebook, etc.) that would make it easier.

I was wondering if we can allow Admins to add Accounts for the Member Models? with out them having to confirm it if the Admin adds it?
I have two Devise Models
Admins
Members
To Launch the application i want to restrict Registration and Admins will create the Logins for Members from the Admin Scope. When he adds the Member i dont want them to confirm their account but just send a welcome Email may be with the login details.
I don't want them to confirm their account but just send a welcome Email may be with the login details
One way you could do this is by simply writing a new user form, saving the user and manually sending an email. If you are using Devise confirmable, then you must call confirm! on the built object, in order for them to log in.
However, sending a password in plain text is generally speaking a dodgy thing to do. Surely you'd then want to force each user to change their password anyway, for security reasons? As such, I'd recommend going for the more standard approach of Devise invitable - which will send an invitation token to the user, and ask them to set their initial password. You achieve this by calling invite! on the built user object.
Here are two RailsCast videos about Devise, which you may find helpful for further reference and examples:
http://railscasts.com/episodes/209-introducing-devise
http://railscasts.com/episodes/210-customizing-devise
Yes you can, just create the object and call confirm on it :)
However, as members will need a password to access their account, it could be nice to email them a link to enter this password, so this link could also confirm the account for you.
IMHO, It's a bad practice to send any password by email, a lot of email servers don't implement any secured protocol, better let your users chose it, with a one-time link
Within a rails app i'm working on. I'm trying to add the ability for users to signup simply by entering their email address and then confirming their account via the confirmation email. I don't want the user to have to enter in any password. How would I go about doing this?
This example is useful, but requires for the user to enter a password: https://github.com/plataformatec/devise/wiki/How-To:-Email-only-sign-up
Should I just automatically use one password for all users?
Devise is built for authentication, which is either a password, or a quick check with a social network that this is actually the person they claim to be. The email address is used as identification.
If you just want to identify a person by their email, I suggest you create your own system for it. You can even add some of the Devise features in if you like. First, create a User model with an email attribute:
rails generate model User email:string
Once you've migrated the database, create a controller for it:
rails generate controller users
Then create a Session model and let each User create sessions by logging in. There'll be plenty of great tutorials on the web of how to create a system like this. Writing helper methods like current_user or user_signed_in? should be quite easy too.
Now for the last point, if you want people to sign in after they signed up using the email confirmation, how will you make sure that it is actually the same person signing in as the person who confirmed the email? Any malicious user could simply use an already confirmed account to sign in, unless you have to do an email confirmation every time you sign in...
So while you can do the above, I would seriously recommend to have some kind of authentication, whether it be with a password, or using OmniAuth to connect to social networks. There's a railscast for that here.
Not sure if this would help you, but based on the simplicity of the authentication process, I would suggest not to use Devise at all. You can just create an action in your SessionsController, which will compare the params[:email] (or however you are calling it in your app) against the emails listed in the UsersTable.
Is it possible to send an email with a user with a link that automatically sign him in based on authentication_token or something similar? (No login required).
Sure, it is possible. Just send a link to login with a query string containing the username that should be logged in. When your login code gets this, sign the user in.
Just be sure to generate a unique token instead of just using email/username
And also you should tell users that the link can be used to sign in since they might forward it to others.
I'm trying to do the following: I have a page with a form for login and password.
Is it possible to use this form for both registration and authorization. For example i'm visiting the page for the first time and enter my email and password. Then if such email already exists i get an error, otherwise an account is created for me. Searching for the way of implementing this gave no results.
Does anyone know hot to make it possible?
This approach has one drawback: If user mistyped password then he would probably never login again. Solution - to use email for password recovery.
Other approach is to let user input email and while user will type password check if email is already in database. If it's not available then add password confirmation field to the form.
How to make it possible? Just program the necessary logic on server-side and client-side.
How can I use both registerable and omniauthable modules in Devise?
Specifically I'd like to be able to let users do the following:
Register/login with email and password
Register/login with Facebook (via omniauth)
Attach or remove a Facebook account to their account so they can login with either their email or their Facebook account.
I don't know how to do 3 at all.
1 and 2 are done, but where it gets weird is if the user registered with a Facebook account, I don't need to show (or require) them to enter a password to update their profile.
So, how can I...
Let users attach a Facebook account to their current account so they can login with either.
If the user only signed up with a Facebook account, how do I hide (and not require) the password fields when editing their settings.

in the user setting page add a link to "link to Facebook account"
the link just drive the user through the normal Facebook authentication processes using the OmniauthCallbacksController, just make sure in your OmniauthCallbacksController facebook method you add some code to see if the user is already logged in and if he is you just add an authentication token for the user (I have a table that stores the authentication token for each user)
If the user only signed up with a Facebook account, how do I hide
(and not require) the password fields when editing their settings.
Take a look at this: https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-edit-their-account-without-providing-a-password
Hope this help.

Just ran through this myself as I was looking into the same thing, and it worked great for me, but one additional note that is incredibly easy to overlook as it's barely mentioned in a single paragraph; don't forget to generate a migration to add facebook_uid to the user model.
