It's an exercise to work with ActiveRecord, an ORM for Ruby on Rails.
In this project we have created a project in which we play with the relations of our models:
- User: has many posts as has many comments.
- Post: belongs to a user.
- Comments: belongs to a user as belongs to a post.
The rules above are set up in the model files corresponding to the same name.
Also with the validations
- Ruby programming language
- Ruby on Rails framework
Setting up you environment
To get a local copy up and running follow these simple example steps.
- Have installed Ruby
- Have installed Rails
- Get a copy of this repo
Once you have the prerequisites open the folder of the project, open a terminal and run rails c to open the rails console.
You can follow the next steps to check how the relations between users, posts, and comments work.
- Create two users:
u1 = User.create(username: "User01", email: "user01@email.com")andu2 = User.create(username: "User02", email: "user02@email.com"). - Create a post for the first user
u1.posts.create(title: "Title of the first post", body: "Body of your first post"). - Make a comment from the second user about the first user's post
u1.posts.first.comments.create(body: "Nice post body!", user_id: 2). - Check the relations:
- c1 = u2.comments.first should return that user’s comment. #comments returns an array with comments, which is why we need to use #first to actually retrieve the comment itself.
- c1.user should return that comment’s author User (u2).
- p1 = Post.first
- p1.comments.first should return the comment c1.
- c1.post should return the post p1.
