How to build user reviews and ratings in Bubble

To build user reviews and ratings in Bubble, you create a Review data type, link each review to the User who wrote it and the thing being reviewed (for example, a Product), let users submit reviews through a form, and then calculate the average rating dynamically using searches. Bubble handles this with normal database fields and repeating groups, no plugins required.

Data Structure

• Create a data type Review.
• Add fields: rating (number), comment (text), reviewer (User), product (Product).
• On your Product data type, add a field reviews (list of Reviews) to make searches faster.

Submitting a Review

• Place inputs on the page: a dropdown or stars for rating, a multiline input for comment.
• Use a workflow: When Submit button is clicked → Create a new Review.
• Set its fields from inputs, and set reviewer = Current User, product = Parent group's Product.
• Optional workflow step: Make changes to Product → add this Review to its reviews list.

Displaying Reviews

• Use a Repeating Group with data source: Search for Reviews where product = Current Product.
• Inside the cell, show the rating, comment, and reviewer’s name.

Average Rating

You can compute the average dynamically. Example: on a text element, set the text to

Search for Reviews:average of rating

Make sure the search contains a constraint: product = Current Product.

Privacy Rules

• In Data → Privacy → Review, allow everyone to read comment and rating.
• Allow Current User is This Review's reviewer to modify or delete.

A Simple Example Workflow

Create a new Review
rating = RatingInput's value
comment = CommentInput's value
reviewer = Current User
product = Parent group's Product

This structure works for any review system: products, services, listings, freelancers, etc. It’s fast, stable, and uses only Bubble’s built‑in functionality.
