confirmable feature bugs?

[seoyoochan]

I don't use 'devise' gem, but only an initializer devise.rb.
I successfully sent a email confirmation link with the following signed up user.
but I believe I found some problems about the confirmable feature.
Please check them if I was correctly realized.

problem

** the generated confirmation link lost the full length of the confirmation token. **
the confirmation token is

:confirmation_token => "d2880361f4baaf0c8304f393a3d6a41a49042f6e4ee2f2d3703f24b503bd6d8f"

<%= link_to 'Confirm my account', confirmation_url(@resource, {confirmation_token: @token, config: message['client-config'].to_s, redirect_url: message['redirect-url']}).html_safe %>

the above link actually returns this url address.

http://api.localhost:3000/v1/auth/confirmation?config=default&confirmation_token=ammABW7Y2ge1yUGk5xN3&redirect_url=http%3A%2F%2Flocalhost%3A9000%2F%23welcome

when I clicked the link it requests GET to omniauth/confirmation!
What the heck is going on?
so,, I've been debugging about this problem and realized User instance does not have the Devise gem's method, which is 'confirm_by_token' method.
the method is used to find a user by its confirmation token and try to confirm it.
Look at the below

2.2.2 :003 > User.first.confirm_by_token("d2880361f4baaf0c8304f393a3d6a41a49042f6e4ee2f2d3703f24b503bd6d8f")

Am I completely doing wrong about implementing email confirmation feature or what?

@seoyoochan I know its late in the game on this one, but did you ever come to a conclusion?

Hi there @seoyoochan ,

In an effort to cleanup this project and prioritize a bit, we're marking issues that haven't had any activity in a while with a "close-in-7-days" label. If we don't hear from you in about a week, we'll be closing this issue. Obviously feel free to re-open it at any time if it's the right time or this was done in error!

If you are still having the issue (especially if it's a bug report) please refer to our new Issue Template to provide some more details to help us solve it.

Hope all is well.
