Database of every climb graded 9a or harder

Setup

Requirements:

• PostgreSQL
• Docker (+ Docker Compose version 2.0 or higher)

Step 1: Load database from backup

1. In the Postgres desktop client, initialize and/or start your server.

2. Create a new database 9a by entering the following command in the terminal:

   createdb -T template0 9a
   

3. Replace 'username' with your username in the backup file by running the following command:

   sed -i '' 's/username/[your username]/g' backups/9a20230828.sql
   

4. Load backup:

   psql 9a < backups/9a20230828.sql
   

Step 2: Create a GraphQL endpoint with Hasura

1. Get the Compose file & start the containers by entering the following terminal commands:

   • Get the Compose file:

       curl https://raw.githubusercontent.com/hasura/graphql-engine/stable/install-manifests/docker-compose/docker-compose.yaml -o docker-compose.yml
     

   • Start the Hasura GraphQL Engine and the Postgres database in Docker containers:

       docker compose up -d
     

2. Connect 9a:

   • Open the Hasura Console by navigating to http://localhost:8080/console in your browser. From the Console, click the Data tab.

     

   • Create a new database using postgresql://[username]@host.docker.internal:5432/9a as the database URL.

     

   • Add all tables and relationships by clicking "Track All" for tables and relationships.

     

3. Manually rename the following GraphQL relationships by going to the Relationships tab in each table:

   • climber:
     • country -> home_country
   • media:
     • ascent_media -> media_ascents
     • climb_media -> media_climbers
     • climber_media -> media_climbs
   • ascent_media, climb_media, climber_media:
     • medium -> media
