How do I build a "Like" system?
Hey there, Tadabase users! Welcome to another episode of Build It with Tim. In today's video, we're going to focus on building a like system using Tadabase. Our goal is to create an application called "database" where users can vote on their favorite cats. We'll explore three different methods, starting from the simplest and gradually increasing in complexity.
To achieve this, we'll make use of various features within Tadabase. Let's dive right into the instructions!
In the most basic approach, we'll start by adding a number field called "likes" to a single table named "cats." This will allow users to like or dislike cat pictures. We'll use the list component to display the pictures, using the attachments field as the cover image for an aesthetically pleasing layout. To control the upvotes and downvotes, we'll incorporate action links.
Within the list component, we'll add two action links, one for liking and one for disliking a cat picture. The likes and dislikes will be tracked and displayed through a number field. Clicking the like button will increment the likes by one, while clicking the dislike button will subtract one.
Moving on to a more advanced approach, we'll introduce user association with actions. To achieve this, we'll create a separate table called "user actions" with two connection fields: one for the user and another for the cat. Additionally, we'll add a field called "like action type" to distinguish between likes and dislikes.
The user actions table allows us to keep track of each user's interactions with the cat pictures. By inserting connected records, we associate the logged-in user with their like or dislike action. The likes and dislikes will be counted using rollup fields based on the action type in the user actions table.
To implement these changes, we'll modify the list component to display the likes and dislikes counts. We'll also update the action rules to include the action type and associate it with the user.
With these enhancements, users will be able to log in, like or dislike cat pictures, and their actions will be recorded and counted accurately.
That's it for today's tutorial on building a like system using Tadabase. We've explored both a simple and a more advanced approach to cater to different requirements. Whether you're building a public-facing voting system or one with user association, Tadabase provides the necessary features to create a robust and customizable application.
