Meet DuckGPT: How ChatGPT Became My Rubber Duck (and made me young again)

Rubber Ducking Evolved

Rubber duck debugging is an interesting concept that many developers are familiar with. The idea originates from a method in which a developer explains their code or problem to an inanimate object (traditionally a rubber duck) to clarify their own thoughts. The act of explaining forces you to think through the problem logically, often leading to a solution.

On May 18th 2023 OpenAI Introduced the ChatGPT app for IOS, with many features including DuckGPT (it's not really call that - but it integrates a speech-recognition system that enables voice input and it syncs your history across devices),

I have a little dog named "Leo" that I walk many times a day. I put on my Apple AirPods Max, load up some podcasts, and away we go. During these walks, I come up with some of my best ideas. I used to use the voice memo app to save my thoughts, but now I use the ChatGPT app. One day, when we returned home, I forgot to turn off the app before starting a debugging session, working on some complex sql issue, and started talking to my rubber duck. When it answered my questions verbally and displayed that answer on the browser, it was magical, the hatching of DuckGPT (a rubber duck the talks back)

A practical example

In the open-source GridLinks project, the time had come to introduce a data store and expose its content using RBAC (role-based access control) through an auth-protected microservice. While the method of picking the data store is fodder for another article altogether, let's just assume PostgreSQL was a very reasonable choice.

Gridlinks is a chrome extension that defines a named grid of links as a set of 8 panels, each containing a maximum of 8 rows and up to 4 columns per row for a total of 256 links per grid. A user may have access to an unlimited number of grids but should be able to choose from up to N active grids at any given time (for now N will be 4). I envision that a user picks 4 grids and a backend AI process is busy creating more grids based on the a users activity.

We already know that the extension consumes some JSON data which is packaged in panels, and we have the definition of at least fifteen of the panels to date.

The data for a panel is semi-structured and can be described by a pretty simple JSON schema.

{
   "$schema": "http://json-schema.org/draft-04/schema#",
   "type": "object",
   "properties": {
      "name:": {"type": "string" },
      "title": {"type": "string" },
      "href1": {"type": "string" },
      "href2": {"type": "string" },
      "links": {
         "type": "array",
         "items": [
            {
               "type": "object",
               "properties": {
                  "label":{ "type": "string" },
                  "pre1": {"type": "string" },
                  "pre2": {"type": "string" },
                  "pre3": {"type": "string" },
                  "pre4": {"type": "string" },
                  "post1":  {"type": "string" },
                  "post2":  {"type": "string" },
                  "post3":  {"type": "string" },
                  "post4":  {"type": "string" },
                  "name1":  {"type": "string"},
                  "href1":  {"type": "string"},
                  "title1": {"type": "string"},
                  "name2":  {"type": "string"},
                  "href2":  {"type": "string"},
                  "title2": {"type": "string"},
                  "name3":  {"type": "string"},
                  "href3":  {"type": "string"},
                  "title3": {"type": "string"},
                  "name4":  {"type": "string"},
                  "href4":  {"type": "string"},
                  "title4": {"type": "string"},
               }
            }
         ],
         "minItems": 8,
         "maxItems": 8
      }
   },
   "required": ["title1", "href1", "href2", "links"]
}

So with this overview in place, we can think about how to design our datastore to efficiently deliver per-user content.

Enter the Duck

Given our definition of the grid from above, create an efficient datastore using PostgreSQL. Examining this conceptual schema reveals a pretty normalized structure; however, you will quickly notice the missing definitions for any data.

In PostgreSQL, jsonb is a data type that stores JSON (JavaScript Object Notation) data in a binary format, allowing for efficient querying and indexing. Unlike the json type, jsonb eliminates whitespace, stores keys in a predefined order, and supports indexing, making it better suited for performance-intensive operations involving JSON data. This type is ideal for scenarios where you need to store and query structured, semi-structured, or unstructured data.

Let's create the database using the conceptual schemas and jsonb as a means to store our panel data.

CREATE TABLE
   users (
      id SERIAL PRIMARY KEY,
      name VARCHAR(255) UNIQUE NOT NULL,
      role VARCHAR(255) DEFAULT 'user',
      dbu VARCHAR(255) DEFAULT CURRENT_USER,
      created TIMESTAMP DEFAULT CURRENT_TIMESTAMP
   );

CREATE TABLE
   grids (
      gid SERIAL PRIMARY KEY,
      name VARCHAR(255) UNIQUE NOT NULL,
      panels JSONB,
      dbu VARCHAR(255) DEFAULT CURRENT_USER,
      created TIMESTAMP DEFAULT CURRENT_TIMESTAMP
   );

CREATE TABLE
   usergrids (
      ugid SERIAL PRIMARY KEY,
      id INT REFERENCES users(id) ON DELETE CASCADE,
      gid INT REFERENCES grids(gid) ON DELETE CASCADE,
      isactive BOOLEAN DEFAULT TRUE,
      dbu VARCHAR(255) DEFAULT CURRENT_USER,
      created TIMESTAMP DEFAULT CURRENT_TIMESTAMP
   );

CREATE TABLE
   panels (
      pid SERIAL PRIMARY KEY,
      name VARCHAR(255) UNIQUE NOT NULL,
      links JSONB,
      dbu VARCHAR(255) DEFAULT CURRENT_USER,
      created TIMESTAMP DEFAULT CURRENT_TIMESTAMP
   );

The Power of Asking the Right Questions

How do we convert our hand coded yaml files into database tables? Ask the duck (ala copilot):

  • Can we create a node based script named y2j that runs js-yaml.js on files in the data/yaml folder and pipes stdout to the data/json folder?

  • Given the table "panels", I want to create a script named j2s that takes json files prepared by y2j and converts them into a sql insert statement?

These prompts let the duck spit out complete scripts that with a few minor tweaks that accomplished my goals in less time then it has taken to explain it.

Now thinking about how to get data in make you think about how to get data out.

The Challenge of JSONB Queries

JSONB, with its ability to store JSON data in a binary format, offers a powerful tool for developers. It allows for efficient storage, indexing, and querying of JSON data in PostgreSQL. However, writing queries that leverage this power can be tricky. The syntax can be complex, and ensuring that you're accessing and manipulating the data correctly often requires a deep understanding of both SQL and the structure of your JSON data

You can use the arrow operators in a sql query:
-> Use this when you need to access nested JSON structures or when you want to work with the data as JSON (e.g., further JSON manipulation)

->> Use this when you want to extract the value as plain text (e.g., for comparison in SQL queries or when you don't need to maintain JSON formatting).

SELECT data->'key' AS value FROM your_table 
WHERE data->>'another_key' = 'some_value';

When faced with a challenging SQL query, especially one involving JSONB, I often turn to DuckGPT. But it’s not just about getting the right answer—it's about knowing how to ask the right question. This is where the process becomes both an art and a science.

💡
Create a query that returns a json array of grid names as gridset for each user. Then with respect to gridlinks explain 2 more variations achieved by including the commented lines (and removing the extra stuff). When thinking about gridlinks what would you say about these queries

Query 1

SELECT 
    u.name AS username,
    COALESCE(json_agg(g.name), '[]'::json ) AS gridset
FROM 
    cmc.users u
JOIN 
    cmc.usergrids ug ON u.id = ug.id
JOIN 
    cmc.grids g ON ug.gid = g.gid
GROUP BY 
    u.id, u.name;
  • Explanation: This query selects the username and a JSON array (gridset) of grid names associated with each user. If a user has no grids, the COALESCE function ensures that an empty JSON array ('[]'::json) is returned.

  • Use Case: This is a general query that can be used to retrieve all users and their associated grids. It's flexible and doesn't filter out inactive grids, making it useful when you want a comprehensive overview of user-grid associations.

Query 2

SELECT 
    u.name AS username,
    COALESCE(json_agg(g.name) FILTER (WHERE ug.isactive = TRUE), '[]'::json ) AS gridset
FROM 
    cmc.users u
JOIN 
    cmc.usergrids ug ON u.id = ug.id
JOIN 
    cmc.grids g ON ug.gid = g.gid
GROUP BY 
    u.id, u.name;
  • Explanation: This query is similar to the first but adds a FILTER clause to include only active grid associations (ug.isactive = TRUE). It also ensures that users without active grids receive an empty JSON array.

  • Use Case: This query is more refined, focusing on active associations only. It’s particularly useful for scenarios where only current, active grid associations are relevant. This aligns well with Gridlinks' objective to display up-to-date, relevant information for users.

Query 3

SELECT 
    u.name AS username,
    COALESCE(json_agg(g.name) FILTER (WHERE ug.isactive = TRUE), '[]'::json ) AS gridset
FROM 
    cmc.users u
JOIN 
    cmc.usergrids ug ON u.id = ug.id
JOIN 
    cmc.grids g ON ug.gid = g.gid
WHERE 
    u.name = 'codemarc'
GROUP BY 
    u.id, u.name;
  • Explanation: This query is identical to the second one but adds a WHERE clause to filter the results for a specific user (u.name = 'codemarc').

  • Use Case: This is a targeted query for when you need to retrieve grid information for a specific user. In the context of Gridlinks, it’s useful for generating user-specific data, such as when a user logs in and the system needs to fetch their grids and associated panels.

And Finally....

💡
Given a user name I want to query username, role, list of grids and for each grid I want the list of panel names and the panel links object, the returned panel links object should be ordered using the panels field of the grids table
SELECT 
    u.name AS username,
    u.role AS userrole,
    g.name AS grid_name,
    json_agg(
        json_build_object(
            'panel_name', p.name, 
            'links', p.links
        ) 
        ORDER BY array_position(array(SELECT jsonb_array_elements_text(g.panels)), p.pid::text)
    ) AS panels
FROM 
    cmc.users u
JOIN 
    cmc.usergrids ug ON u.id = ug.id
JOIN 
    cmc.grids g ON ug.gid = g.gid
JOIN 
    cmc.panels p ON p.pid = ANY(ARRAY(SELECT jsonb_array_elements_text(g.panels) :: int))
WHERE 
    u.name = 'codemarc'  
    AND ug.isactive = TRUE
GROUP BY 
    u.name, u.role, g.name, g.panels;

Explanation:

  • u.name AS username: Retrieves the username.

  • u.role AS userrole: Retrieves the user role.

  • g.name AS grid_name: Retrieves the name of each grid.

  • json_agg(...) AS panels: Aggregates the panels into a JSON array of objects, each containing the panel name and its links.

  • ORDER BY array_position(...): Orders the panels in the JSON array based on the position specified in the panels field of the grids table.

  • JOIN clauses: Connects the users, usergrids, grids, and panels tables.

  • p.pid = ANY(...): Filters the panels based on the list of panel IDs in the panels JSONB array from the grids table.

  • WHERE clause: Filters the results to include only the specified username and active grids.

  • GROUP BY clause: Groups the results by the username, user role, grid name, and panels field to ensure proper aggregation.

Key Points:

  • Replace 'codemarc' with the actual username you're querying for or use a parameter if this query is part of an application.

  • Ordering: The ORDER BY array_position(...) ensures that the panels are ordered according to their position in the panels JSONB field of the grids table.

This query provides a detailed, ordered JSON output that aligns well with the requirements of Gridlinks or any similar application. If there are any further adjustments or clarifications needed, feel free to ask!
