PG::DuplicateColumn: ERROR: column "avatar_file_name" of relation "users" already exists? - ruby-on-rails

How do I solve this?
I have no issues locally as I run rake db:migrate successfully. But on Heroku, I get this.
and when I run heroku run rake db:migrate --trace
$ heroku run rake db:migrate --trace

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
This problem occurs even if I drop the database, comment out specific fields like, for example, encrypted_password in migration file. I've also tried to reset migration, set it to development mode. I'm using Devise and trying to run this migration file. If anyone got any ideas of why or how this happens I'd appreciate some ideas to fix this issue.
Could this happen because of an error in a certain file?
Migration status:
database: fitnesshabbits_development
Status Migration ID Migration Name
--------------------------------------------------
up 20190227233216 Devise create users
down 20190301194540 Add devise to users
I think that you have add the same field in your two migrations.
I think that you have add encrypted_password in you AddDeviseToUsers migration.
Lock that in your migrations don't have field that are repeat.

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
When I ran rails c this is what I got:
2.3.0 :001 > Post.column_names
=> ["id", "title", "link", "description", "created_at", "updated_at", "user_id", "image_file_name", "image_content_type", "image_file_size", "image_updated_at", "cached_votes_total", "cached_votes_score", "cached_votes_up", "cached_votes_down", "cached_weighted_score", "cached_weighted_total", "cached_weighted_average", "image"]
I know that there is a way to remove the "image_file_name" duplication but I am not really aware of how to do so to my app. I did find some posts that are similar to my problem but nothing really solved it!
Because you deleted the migration for creating the column, and if you create a migration to delete it, it will cause error in other environment(production), as there is no column to be deleted at first place.
Assuming you haven't deploy the migration to production.
You can just drop the column directly in database console.
run rails dbconsole
and
ALTER TABLE posts DROP COLUMN image_file_name;
First of all, you should never just remove a migration. If you want to remove a field you should create a new migration for it.
You have 2 options now, or you can rake db:migration:reset that will recreate your entire database OR you can comment the content on this last migration, run rake db:migrate and after that you can uncomment it.

How to write a migration changing id to uuid

class ChangeIdtoUuiDforcarts < ActiveRecord::Migration
def change
rename_column :carts, :id, :uuid
change_column :carts, :uuid, 'using uuid::uuid'
end
end
I have tried the above migration, but it gives the following syntax error
-- rename_column(:carts, :id, :uuid)
-> 0.0032s
-- change_column(:carts, :uuid, "using uuid::uuid")
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
PG::SyntaxError: ERROR: syntax error at or near "using"

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
I have already enabled the uuid in another migration, and I don't want to drop the db So I can write id: :uuid in create table statement itself

ActiveRecord::PendingMigrationError: Migrations are pending. To resolve this issue, run: bin/rake db:migrate RAILS_ENV=development

NEWBIE: I am trying to set up the membership part of my site. I ran the following commands:
git checkout development
git merge user_authentication
git checkout -b stripe_integration
bundle exec rails g migration CreatePlans
and received the this error:
ActiveRecord::PendingMigrationError: Migrations are pending. To
resolve this issue, run: bin/rake db:migrate RAILS_ENV=development
I've tried running it and other commands with no success. Below are links to other Stack Overflow answers to this issue that did not work for me and a full trace.

Which email should I remove from the add_devise_to_user.rb file?
class AddDeviseToUsers < ActiveRecord::Migration

# By default, we don't want to make any assumption about how to roll back a migration when your
# model already existed. Please edit below which fields you would like to remove in this migration.
raise ActiveRecord::IrreversibleMigration
end
end
Looking into the AddDeviseToUsers migration error stack trace, you may notice that you have a duplicate email column. You already have an email column on the users table and that particular migration is trying to add another one.
I'd advise you to edit AddDeviseToUsers to remove the email column creation. If you're not familiar with Rails directory structure, you may find that file at db/migrate/xxxxxxxxxxx_add_devise_to_users.rb
I hope it helps.

RoR Rake migration doesn't succeed

I'm trying to do a rake db:migrate on RoR. However after running the command I get the following error (I've included trace as well). Can you please tell me how it can be soled? I have tried to rollback and repeat the procedure but it's not working.... :
Malions-MacBook-Air:omrails malionhoxhallari$ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)

Tasks: TOP => db:migrate
Did you follow all the steps in the Devise readme(https://github.com/plataformatec/devise)?
Make sure you ran:
rails g devise:install
and
rails g devise User
before migrating.
Since the first part of the trace shows: SQLite3::SQLException: no such table: users so the first thing I would do is check the migration file and schema.rb to see if you've created the users table properly.
Here's an example of a working schema.rb and migration using Devise:
schema.rb:
create_table "users", force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.inet "current_sign_in_ip"
t.inet "last_sign_in_ip"
t.datetime "created_at"
t.datetime "updated_at"
t.string "role"
end
Corresponding migration to update schema:
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.string :email, null: false, default: ""
t.string :encrypted_password, null: false, default: ""
## Recoverable
t.string :reset_password_token
t.datetime :reset_password_sent_at
## Rememberable
t.datetime :remember_created_at
## Trackable
t.integer :sign_in_count, default: 0, null: false
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.inet :current_sign_in_ip
t.inet :last_sign_in_ip
## Confirmable
# t.string :confirmation_token
# t.datetime :confirmed_at
# t.datetime :confirmation_sent_at
# t.string :unconfirmed_email # Only if using reconfirmable
## Lockable
# t.integer :failed_attempts, default: 0, null: false
# t.string :unlock_token # Only if unlock strategy is :email or :both
# t.datetime :locked_at
t.timestamps
end
add_index :users, :email, unique: true
add_index :users, :reset_password_token, unique: true
# add_index :users, :confirmation_token, unique: true
# add_index :users, :unlock_token, unique: true
end
end
