Welcome back to my blog series on building a project management app with Ruby on Rails 7 and ChatGPT integration! In this post, we'll create controllers and views for our app, integrate with the OpenAI API, and implement project briefing and project plan creation functionalities. If you haven't yet, start with Part 1 where we begin by setting up the project and OpenAI API.
Step 1: Creating Controllers for Project Briefings and Project Plans
Generate controllers for ProjectBriefings and ProjectPlans:
rails generate controller ProjectBriefings rails generate controller ProjectPlans
Step 2: Setting up Routes
Update your config/routes.rb file with the following:
Rails.application.routes.draw do devise_for :users resources :project_briefings resources :project_plans root to: 'project_briefings#index' end
Step 3: Creating Views for Project Briefings and Project Plans
Create views for listing, creating, and editing project briefings and project plans. You can use Rails' scaffold generator as a reference to create views with basic CRUD functionality:
rails generate scaffold_controller ProjectBriefing --skip rails generate scaffold_controller ProjectPlan --skip
Copy the generated views from app/views/project_briefings and app/views/project_plans into their respective folders.
Step 4: Integrating OpenAI API
Create a new service called OpenaiService:
mkdir app/services touch app/services/openai_service.rb
Add the following code to app/services/openai_service.rb:
class OpenaiService
def self.create_document(prompt)
Openai::Completion.create(
engine: "text-davinci-002",
prompt: prompt,
max_tokens: 500,
n: 1,
stop: nil,
temperature: 0.7
)
end
endStep 5: Implementing Project Briefing and Project Plan Creation
Update the ProjectBriefingsController and ProjectPlansController to integrate with the OpenAI API when creating a new project briefing or project plan:
class ProjectBriefingsController < ApplicationController
# ...
def create
@project_briefing = current_user.project_briefings.build(project_briefing_params)
prompt = "Create a project briefing for a software project with the following title and description: #{project_briefing_params[:title]} - #{project_briefing_params[:description]}"
response = OpenaiService.create_document(prompt)
@project_briefing.description = response.choices.first.text
if @project_briefing.save
redirect_to @project_briefing, notice: 'Project briefing was successfully created.'
else
render :new
end
end
# ...
end
class ProjectPlansController < ApplicationController
# ...
def create
@project_plan = current_user.project_plans.build(project_plan_params)
prompt = "Create a project plan for a software project with the following title and description: #{project_plan_params[:title]} - #{project_plan_params[:description]}"
response = OpenaiService.create_document(prompt)
@project_plan.description = response.choices.first.text
if @project_plan.save
redirect_to @project_plan, notice: 'Project plan was successfully created.'
else
render :new
end
end
# ...
endThat wraps up Part 2 of our blog series! In this post, we created controllers and views for project briefings and project plans using Simple Form for our forms. We integrated with the OpenAI API to draft comprehensive documents and implemented project briefing and project plan creation functionalities.
In the next post, we'll add user authentication to protect our project briefings and project plans, improve the user interface using Bootstrap, and deploy our application to a production environment. Don't miss the exciting conclusion of our series, and thank you for joining us on this journey!
