When I'm trying to migrate my database I get an error Mysql2::Error: Table 'database.lorem_ipsum' doesn't exist: SHOW FULL FIELDS FROM ``lorem_ipsum. I've created database before by rake db:migrate
config/database.yml
development:
adapter: mysql2
database: database
username: root

Can you try this ?
test:
adapter: mysql2
encoding: utf8
reconnect: false
database: database
pool: 5
username: root
password:
On your database.yml

I switched from sqlite to mysql in my rails 3 application. I'm getting the following error when I try to run the server.
Users/harshkumar/.rvm/gems/ruby-2.3.7/gems/activerecord-3.2.21/lib/active_record/connection_adapters/abstract/connection_specification.rb:133:in 'establish_connection': database configuration specifies nonexistent mysql2 adapter (ActiveRecord::AdapterNotFound)
I have included mysql2 gem in the gemfile. My rails version is 3.2.21 and mysql2 gem version is 0.3.21
development:
adapter: mysql2
encoding: utf8
pool: 5
database: sys
username: root
password:
host: 127.0.0.1
port: 3306
test:
adapter: mysql2
database: sys
encoding: utf8
pool: 5
username: root
password: ''
production:
adapter: mysql2
database: sys
encoding: utf8
pool: 5
username: root
password: ''
This is my database.yml file
update: I got this error when I fixed my pervious problem with this solution:
Mysql2::Error: All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead
While running the command rake db:create, the system throws postgresql authentication fails
FATAL: password authentication failed for user "postgres"

database.yml file
default: &default

I guess the problem is setup password on postgresql if you don't remember the default password then go to pgAdmin click to open dashboard and then the left sidebar see the below image
Click the Properties... then will open a modal like see the below image
and click the Definition tab and see the Password field and set the new password, remember this password for postgres username.
That's is for password setup!
Now update your database.yml file like below
default: &default
adapter: postgresql
encoding: unicode
username: postgres
password: 123456 #=> which you set for postgres
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: project_development
Hope to help

Please help how to create PostgreSQL database connection in my RoR app.
You can change host: 127.0.0.1 to host: localhost. It should solve the issue.
First install pg gem
gem install pg
your apps database.yml file shoud be like this
development:
adapter: postgresql
encoding: unicode
database: myapp_development
pool: 5
username: myapp
password: password1
test:
adapter: postgresql
encoding: unicode
database: myapp_test
pool: 5
username: myapp
password: password1
Now run
rake db:setup
rake db:migrate
and after this run
rails s
Use this link to verify, Is Postgresql installed successfully or not.

Removed host from development config in database.yml,its worked for me.
development:
adapter: postgresql
database: tes
pool: 5
timeout: 5000
username: postgres
password: root
First you should install PostgreSQL and PgAdmin
After installing this thing you will have to add some pic of code ( to connect PostgreSQL to your rails project ) in your project config/database.yml file (before add PostgreSQL code you will have to remove all Sqlite3 code from config/database.yml file).
development:
adapter: postgresql
encoding: unicode
database: database_name
pool: 5
host: localhost
username: your_PostgreSQL_username
password: your_PostgreSQL_password
test:
adapter: postgresql
encoding: unicode
database: database_name
pool: 5
username: your_PostgreSQL_username
password: your_PostgreSQL_password
staging:
url: <%= ENV['DATABASE_URL'] %>
production:
url: <%= ENV['DATABASE_URL'] %>
postgres is default username and password in PostgreSQL database\
after add this pic of code you have to add one line of code in your rails project root directory in Gemfile
gem ‘pg’
and you must have to remove sqlite3 code from Gemfile ( gem 'sqlite3', '~> 1.4' )before adding gem 'pg'
Rails new app.
The current database.yml is like that:
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
development:
adapter: sqlite3
database: db/development.sqlite3
pool: 5
timeout: 5000
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000
production:
adapter: sqlite3
database: db/production.sqlite3
pool: 5
timeout: 5000
I need to edit this for postgresql database.
How can I do this?
Simply:
development:
adapter: postgresql
encoding: unicode
database: blog_development
pool: 5
username: blog
password:
host: localhost
Source: Configuring Rails Applications
development:
adapter: postgresql
encoding: utf8
database: name
username: hading
password: my_db_password
pool: 5 # not mandatory
timeout: 5000 # not mandatory
host: localhost
port: your postgresql port number (5432 or 5433)
As Zabba said it's
development:
adapter: postgresql
encoding: unicode
database: blog_development
pool: 5
username: blog
password:
As mentioned in the Configuring Rails Applications. But you might want an additional min_messages: WARNING, to get rid of the nasty NOTICE messages postgresql gives you during a migration. So my database.yml entry looks like this
development:
adapter: postgresql
encoding: unicode
database: blog_development
pool: 5
username: blog
password:
min_messages: WARNING
You might be interested in generating new app with postgres default:
rails new myapp --database=postgresql
as mentioned here: https://devcenter.heroku.com/articles/getting-started-with-rails4
development:
adapter: postgresql
encoding: utf8
database: name
username: hading
password: my_db_password
host: localhost # not mandatory
pool: 5 # not mandatory
timeout: 5000 # not mandatory
Simply use
rails new app_name --database=postgresql
or if existing application try
development:
adapter: postgresql
encoding: unicode
database: app_dev
pool: 5
username: username
password: password
host: localhost
Another way is to have the common values in &default and then have individual values for the other environments, which can be based on environment variables:
default: &default
adapter: postgresql
encoding: unicode
port: <%= ENV.fetch("POSTGRESQL_PORT", "5432") %>
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: <%= ENV['POSTGRESQL_USER_NAME'] %>
password: <%= ENV.fetch("POSTGRESQL_PASSWORD", "myS3cr3tP4ssw0rd") %>
host: <%= ENV['POSTGRESQL_HOST'] %>
development:
<<: *default
database: <%= ENV['POSTGRESQL_DB'] %>-development
host: db
test:
<<: *default
database: <%= ENV['POSTGRESQL_DB'] %>-test
host: db
production:
<<: *default
database: <%= ENV['POSTGRESQL_DB'] %>
Here all the values can come from environment variables (if you use Docker or Bitbucket Pipelines) or you can have them in your .env files.
