I am trying to execute heroku run rake db:migrate, but that's the result :
rake aborted!
PG::Error: ERROR: invalid value for parameter "client_encoding": "utf8mb4"
I want to use mysql database in development and postgres in production, and so that's the way that I configured my database.yml :
postgres: &postgres
adapter: postgresql
encoding: unicode
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
mysql: &mysql
adapter: mysql2
encoding: utf8mb4
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: root
password:
socket: /var/run/mysqld/mysqld.sock
development:
<<: *mysql
database: event_development
test:
<<: *mysql
database: event_test
production:
<<: *postgres
database: event_production
username: event
password: <%= ENV['EVENT_DATABASE_PASSWORD'] %>
How can I solve this?
Just use url for it. If you have installed "Heroku Postgres" add-on. There supposed to be the DATABASE_URL in config vars.
database.yml:
...
production:
url: <%= ENV['DATABASE_URL'] %>

I am new to RoR, but not new to web development in general.
I am trying to switch a Rails app from sqlite3 to mysql2, it is api-only.
Added the gem to Gemfile, used bundle install, everything fine.
I run rails server and see the error bellow: https://imgur.com/c4Qqf1k
This is my Database.yml:
default: &default
adapter: mysql2
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
encoding: utf8
reconnect: true
host: 127.0.0.1
port: 3306
username: root
password: 123456
socket: /tmp/mysql.sock
development:
<<: *default
database: beginner_dev
test:
<<: *default
database: beginner_test
production:
<<: *default
database: beginner_prod
I succeeded to solve the problem by adding the following lines to database.yml, default section:
ssl_mode: :disabled
sslverify: false
The error isn't so descriptive, but apparently it was related to ssl.
Replace your database.yml content with the following configs
default: &default
adapter: mysql2
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
encoding: utf8
reconnect: true
host: 127.0.0.1
port: 3306
username: root
password: 123456
development:
<<: *default
database: beginner_dev
test:
<<: *default
database: beginner_test
production:
<<: *default
database: beginner_prod
The database of my Rails application is SQLite3, but I want to change it to MySQL. What do I need to do to change it in my application?
This is database.yml from my application:
# SQLite. Versions 3.8.0 and up are supported.
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#
default: &default
adapter: sqlite3
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
database: db/production.sqlite3
You need to update the adapter to MySQL2 and add your credentials. For instance:
development:
adapter: mysql2
encoding: utf8mb4
database: development
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: root
password: password
socket: /tmp/mysql.sock
Look at the offical documentation for more information.
Here is it with defaults:
default: &default
adapter: mysql2
timeout: 5000
encoding: utf8mb4
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
socket: /tmp/mysql.sock
development:
<<: *default
database: development
username: <%= ENV.fetch("username") %>
password: <%= ENV.fetch("password") %>
test:
<<: *default
database: test
username: username
password: password
production:
<<: *default
database: production
username: <%= ENV.fetch("username") %>
password: <%= ENV.fetch("password") %>
You can also encode username and password in the database like this:
mysql://<username>:<password>#<host>:<port>/<db_name>
and then set host. Don't put username and password in your database.yml file.
Everytime I run my rails application I get this error pointing to "encoding: utf8" in the production section of database.yml. If I reload the page it takes me to the app but I'm afraid something is wrong with the database.
Here is my database.yml folder:
default: &default
adapter: mysql2
encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: b6f4e1d86a2a08
password: 25205573
host: us-cdbr-iron-east-05.cleardb.net
development:
<<: *default
database: DBProj_development
test:
<<: *default
database: DBProj_test
production:
<<: *default
adapter: mysql2
encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: b6f4e1d86a2a08
password: 25205573
host: us-cdbr-iron-east-05.cleardb.net
database: #localhost
I completely understand that YAML must be consistently indented using spaces. Tabs are not allowed.I do not think this is the problem. I have not found one only source to remedy this problem.
You have 2 issues there. Wrong level of indentation below adapter in the production label. And the value of the database label can't start with an #, so you have to place it between quotation marks:
default: &default
adapter: mysql2
encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: b6f4e1d86a2a08
password: 25205573
host: us-cdbr-iron-east-05.cleardb.net
development:
<<: *default
database: DBProj_development
test:
<<: *default
database: DBProj_test
production:
<<: *default
adapter: mysql2
encoding: utf8
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
username: b6f4e1d86a2a08
password: 25205573
host: us-cdbr-iron-east-05.cleardb.net
database: "#localhost"
That will fix your parsing issues.

Add mysql2 gem and remove other connection gem required for sql server.
