Devise primary key error on postgresql, heroku, Rails 4

It is really odd, I'm trying to create a new user by command line and I'm getting this error:

User.create :email => "pheewq+1@gmail.com", :password => '123456789', :password_confirmation => '123456789'

PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "users_pkey"
DETAIL:  Key (id)=(37) already exists.
Solution

  • Try This

    $ heroku run rails console
irb(main)> ActiveRecord::Base.connection.tables.each { |t| ActiveRecord::Base.connection.reset_pk_sequence!(t) }
