Building a Knowledge Base with Rails: Categories and Articles

Building a knowledge base is an essential requirement for many websites, providing an organized collection of information that users can refer to. In this article, we will discuss how to create such a system using Rails, focusing on categories and articles as the main components.

Categories

Categories are used to classify articles and provide a structured organization for the knowledge base. In Rails, we can create a Category model using the following command:


rails generate model Category name:string

This will generate a migration file that defines the categories table in the database with a name field. We can then run the migration to create the table:


rails db:migrate

Once the model and database are set up, we can create, edit, and delete categories through Rails controllers and views.

Articles

Articles contain the actual content of the knowledge base. In Rails, we can create an Article model with the following command:


rails generate model Article title:string content:text category_id:integer

This will generate a migration file that defines the articles table with title, content, and category_id fields. The category_id field establishes a relationship between articles and categories, allowing articles to be associated with specific categories.

We can run the migration to create the articles table:


rails db:migrate

To display articles, we can create views that list all articles or filter articles by category. By leveraging Rails’ routing and controllers, we can implement features like article search, pagination, and related articles.

Conclusion

In this article, we explored the process of building a knowledge base with Rails, focusing on categories and articles as the main elements. By defining categories and establishing relationships between articles and categories, we can create an organized information architecture that aids users in accessing and retrieving relevant knowledge efficiently.
