How to rename a tag in GIT

In this post, I will teach you how to rename a tag in git.

Actually, it is pretty easy.


I am going to rename the tag called myOldTag to myNewTag.

Step 1: we create an alias called "myNewTag"

  
     git tag myNewTag myOldTag

  

Step 2: we delete the myOldTag  tag locally

  
     git tag -d myOldTag

  

Step 3: we tell to git repository that myoldTag has been deleted

  
     git push origin :refs/tags/myOldTag

  

Step 4: we save the changes on GIT

  
     git push --tags

Routing Error No route matches [GET] "/users/logout"

The message "Routing Error No route matches [GET] "/users/logout" is because you are sending the request via get and should be delete, so to fix it you have two options:

 The first one  is the  better, change the tag  link_to to button_to, doing that, rails will  do  the dirty work to send it as  a delete request.

The second one is not recommended, since DELETE is the appropiete RESTFUL query , but it works. Got to devise.rb change  config.sign_out_via = :delete to config.sign_out_via = :get
