Has anyone : restricted users to email domain, and used email verification?

[Matt]

Just wondering if anyone has restricted users to a list of email
domains, and also used an email verification to make sure they are
actually using that email.

If I got you right, you're talking about sign up mail accounts. When a user put it into the form you have to validate it (with regular expressions) to match your allowed pattern or to print an error. (you need some code?)

email verification is included in the restful authentication plugin (http://agilewebdevelopment.com/plugins/restful_authentication). See the code if you don't use this or see some alternative.

Basically I want a table of domains for email addresses.

For instance, I want to limit everyone on my lovdbyless to gmail.com.
So someone has to sign up with a gmail.com email address, then the
email has to be verified for account use.

That's easy. Maybe after breakfast. ;)

I think of two approaches for solving this:

1) letting user type their full email address

2) letting user type the prefix of their email address. Ex. bob for b...@gmail.com. User could select from a list of mail hosts like (gmail, hotmail, ...) 

3) add a domain field to the form

-------------------------------------------------------------------------------------

1) extend the regular expression in the user model (~line 33) so that it fits the domains you allow

    validates_format_of :email, :with => /^([^@\s]{1}+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :on => :create, :message=>"Invalid email address or domain."

2) add a select field to your form which get values from (let's say) a constant in your User model where you store the allowed domain like ALLOWED_DOMAIN=[...]. You still can keep the validation for the whole email address (before validation concatenate the two fields).

3) let people type in their username and the domain into the next field (ex. e_domain)

than you can add a validation to that field like

validates_inclussion_of :e_domain, :in => [gmail.com, hotmail.com,....]

That's not the complete code but a point from which you can start.
