- install postgesql
- install the heroku cli
in the gemfile remove:
gem "sqlite3"in the terminal run:
bundle add pg
next we will need to change the db.yml file to look something like:
default: &default
adapter: postgresql
encoding: unicode
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
timeout: 5000
development:
<<: *default
database: your_project_name_development
test:
<<: *default
database: your_project_name_test
production:
<<: *default
database: your_project_name_production
rake db:create db:migrate db:seed
rake server
First run the following command to add additional platforms to your Gemfile.lock
bundle lock --add-platform x86_64-linux
next we need to commit the changes
git add .
git commit -m "switched db from sqlite3 to posgresql"
after we have commited our changes we can create a new heroku app with the heroku cli
heroku create
Next we need to push the code to the heroku repository that was created with the above command. First run the command
git branch --show-current
if it printed out main
git push heroku main
if it printed out master
git push heroku master
Next we need to migrate and seed the database on the server
heroku run rake db:migrate db:seed
