Have an existing DDN project?

Go to your DDN project directory

cd mysupergraph

Run codemod command using DDN

sudo ddn update-cli

From the latest cli, run the following command from your project directory:

ddn codemod enable-promptql

This will make the following changes to your project:

1. Changes to context.yaml:

   • Update the context.yaml file’s definition, to add a promptQL: true entry.
   • Add a new docker-start-promptql script to the context.yaml.

2. Changes to docker compose file used to run Hasura engine:

   • Add a new service called promptql-playground.
   • Optionally add ENABLE_SQL_INTERFACE environment variable in engine service (if not present)
   • Optionally add io.hasura.ddn.service-name label in engine service (if not present)

3. Enable promptQL for the DDN project, and generate a PromptQL API key.

4. Enable promptQL playground for the DDN cloud project, using the LLM api key added in step 1.

Start your assistant

Open a new terminal window, and run the following command from the project directory:

ddn run docker-start-promptql

This command will execute the script found in your .hasura/context.yaml file.

When you run this command, Docker will start the engine, promptql-playground, and any other services present in the docker compose file.

Then run the following command to open the DDN console:

ddn console --local

This should open up your browser (or print a browser URL) for opening up your console. It’ll typically be something like: https://console.hasura.io/local?engine=localhost:3280&promptql=localhost:3282.
