Building a Project Management App with Ruby on Rails 7 and ChatGPT Integration - Part 1: Project Setup and OpenAI API

Coding Posted on Jun 10, 2023
Welcome to my new blog series on building a project management app with Ruby on Rails 7, which integrates with ChatGPT! This app will help software house teams easily create Project Briefings and Project Plans by providing simple prompts and basic information. We'll utilize the OpenAI API to draft comprehensive documents such as creative briefs, project briefings, statements of work, and project management plans.

Step 1: Setting up a New Rails 7 Project


First, make sure you have Rails 7 installed. If not, install it with the following command:

gem install rails --pre 

Now, create a new Rails 7 project:

rails new chatgpt_project_management --database=postgresql --webpacker
cd chatgpt_project_management

Configure your database in config/database.yml, and then run:

rails db:create
rails db:migrate

Step 2: Installing Devise


Add the Devise gem to your Gemfile and run bundle install:

gem 'devise'

Run the Devise generator:

rails generate devise:install 

Follow the instructions output by the generator to complete the setup.

Step 3: Creating a User Model


Let's create a User model for authentication:

rails generate devise User rails db:migrate 

Step 4: Setting up OpenAI API


Add the OpenAI Ruby gem to your Gemfile:

gem 'openai'

Run bundle install.

Next, create an initializer for the OpenAI API configuration:

touch config/initializers/openai.rb 

Add the following code to config/initializers/openai.rb, replacing your_api_key with your actual API key:

require 'openai'

Openai.configure do |config|
  config.api_key = "your_api_key"
end

Remember to add config/initializers/openai.rb to your .gitignore file to avoid exposing your API key in version control.

Step 5: Creating Models for Project Briefings and Project Plans


Generate models for ProjectBriefing and ProjectPlan:

rails generate model ProjectBriefing title:string description:text user:references
rails generate model ProjectPlan title:string description:text user:references
rails db:migrate

That's it for Part 1! In this post, we've set up a new Rails 7 project, installed Devise for authentication, created a User model, and configured the OpenAI API. We've also generated models for Project Briefings and Project Plans.

In the next post, we'll dive into creating controllers and views for our app, integrating with the OpenAI API to draft comprehensive documents, and implementing project briefing and project plan creation functionalities. Stay tuned!
