"Fossies" - the Fresh Open Source Software Archive

Member "discourse-2.8.3/docs/DEVELOPER-ADVANCED.md" (14 Apr 2022, 3505 Bytes) of package /linux/www/discourse-2.8.3.tar.gz:

As a special service "Fossies" has tried to format the requested source page into HTML format (assuming markdown format). Alternatively you can here view or download the uninterpreted source code file. A member file download can also be achieved by clicking within a package contents listing on the according byte size field. See also the last Fossies "Diffs" side-by-side code changes report for "DEVELOPER-ADVANCED.md": 2.7.13_vs_2.8.0.

A hint: This file contains one or more very long lines, so maybe it is better readable using the pure text view mode that shows the contents as wrapped lines within the browser window.

Discourse Advanced Developer Install Guide

This guide is aimed at advanced Rails developers who have installed their own Rails apps before.

Note: If you are developing on a Mac, you will probably want to look at these instructions as well.

Preparing a fresh Ubuntu install

To get your Ubuntu 16.04 or 18.04 LTS install up and running to develop Discourse and Discourse plugins follow the commands below. We assume an English install of Ubuntu.

echo 'gem: --no-document' >> ~/.gemrc

# exit the terminal and open it again to activate RVM

rvm install 2.6.2
rvm --default use 2.6.2 # If this error out check https://rvm.io/integration/gnome-terminal
gem install bundler rake

# Download and install postgresql-10 from https://wiki.postgresql.org/wiki/Apt

# Postgresql
sudo -u postgres -i
createuser --superuser -Upostgres $(cat /tmp/username)
psql -c "ALTER USER $(cat /tmp/username) WITH PASSWORD 'password';"

# Node
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash

# exit the terminal and open it again to activate NVM

nvm install node
nvm alias default node
npm install -g svgo

If everything goes alright, let's clone Discourse and start hacking:

git clone https://github.com/discourse/discourse.git ~/discourse
cd ~/discourse
bundle install

# run this if there was a pre-existing database
bundle exec rake db:drop
RAILS_ENV=test bundle exec rake db:drop

# time to create the database and run migrations
bundle exec rake db:create
bundle exec rake db:migrate
RAILS_ENV=test bundle exec rake db:create db:migrate

# run the specs (optional)
bundle exec rake autospec # CTRL + C to stop

# launch discourse
bundle exec rails s -b # open browser on http://localhost:3000 and you should see Discourse

Create an admin account with:

bundle exec rake admin:create

If you ever need to recreate your database:

bundle exec rake db:drop db:create db:migrate
bundle exec rake admin:create
RAILS_ENV=test bundle exec rake db:drop db:create db:migrate

Configure emails via MailHog (https://github.com/mailhog/MailHog):

docker run -p 8025:8025 -p 1025:1025 mailhog/mailhog # open http://localhost:8025 to see the emails

Discourse does a lot of stuff async, so it's better to run sidekiq even on development mode:

bundle exec sidekiq # open http://localhost:3000/sidekiq to see queues
bundle exec rails server

And happy hacking!
