Other Comments

When creating a new version of the user address, email confirmation is required, so a new version has been created as V1/users. The versioning of the whole API is something that is beyond the scope of this issue, so we opted for the above.

Close #214

Is this a WIP PR? Because there's still some tests breaking in the CI tool.

Now the PR is complete. Now there is the versioning of endpoint /users, where in v1/users email confirmation is required to register new users.

In general, this look ok to me, I just didn't get why there are so many templates that apparently do the same thing. Might be just a technicality tho ¯_(ツ)_/¯

For some reason when I delete templates from the user_mailer folder I get a missing template error. The same happens when I remove templates from the layouts folder. Keeping the two template folders all works beautifully ¯_(ツ)_/¯

By the way, sending emails is using Sendgrid. It would be interesting for a project maintainer to create a Sendgrid account and add the key to the environment.rb file on deploy.

Hey @alaxalves, I added some exceptions, could you review again?
