I want to build a rating functionality identical to what we can see on http://www.meineuni.de/ - there is a page of a product (or an University as in the example) and that page contains cumulative ratings taken from continuous ratings. A sample page is http://www.meineuni.de/uni/jacobs-university-bremen/bewertungen/

Business case: I want anonymous users to be able to create content of specific type and be able when creating the page, to assign ratings in several categories. This page will then be available online for other anonymous users to rate and the rating will be cumulated with the initial rating to show the weighted (initial+continuous) rating.

Is something like this possible with Fivestar in Drupal 7?

I want to find the right way from the beginning, instead of trial and error approach, which I don't mind, but that is more time consuming.

  • from what I remember, fivestar does not have/support cumulative ratings – No Sssweat Feb 4 '16 at 23:43
  • You will have to a bit of your own work. Like Adrian mentions, you could use views calc to find the cumulative rating, then use php if statement to display a certain image output depending on the cumulative rating. – No Sssweat Feb 4 '16 at 23:46
  • do you got some advance? – Adrian Cid Almaguer Feb 9 '16 at 5:09
  • Hi, @Adrian, I followed these instructions: link and was able to have the average rating of the comments to display in the content. What I am not able to achieve is the anonymous users to be able to rate directly when he creates the content - because the Fivestar Widget type must be Stars (rated while viewing). – user48533 Feb 9 '16 at 21:54

Yes, you can do it, you can combine the Views module with the Views Aggregator Plus or with the Views Calc module.

Views Calc:

Adds simple calculations to a views table. You can SUM, AVERAGE, COUNT, MIN, MAX, or AVG selected columns. A plug in theme makes the view look more spreadsheet-like (right justifies numeric fields, shades calculated columns and rows, and underlines calculated rows).

Views Aggregator Plus:

In addition to what Views and Views Calc do, this module:

  • enumerates group members
  • produces tallies, i.e. textual histograms
  • aggregates on Views PHP code-snippet evalutations
  • can filter out result rows on regexp patterns
  • gives you sorting on Views' Math expressions
  • can process Webform submissions
  • lets you add your own custom aggregation functions

... and it puts summary statistics at the bottom of your aggregated table as well!

  • Hi, thanks a lot for your answer, I am not familiar with these modules, will give it a try. – user48533 Feb 4 '16 at 15:11

The Views Calc module (of which I'm a legacy co-maintainer ...) as suggested in the previous answer is indeed something I'd also recommend to investigate. To get an idea of how it is like to use that module, have a look at my answer to "How can I show average votes of fivestar nodes?".

Below are some more options you may want to consider (as per the you used in your question), and which includes the Fivestar module.


The VotingAPI module offers a framework to developers of Drupal modules about voting and/or rating. It uses a standardized API and schema for storing, retrieving, and tabulating votes for Drupal content.

VotingAPI offers these key features:

  • Create/Retrieve/Update/Delete operations for voting data.
  • Whenever a vote is casted, it calculates the results and caches them. These calculations can either be the default calculations (average, total, etc), or they can be implemented via custom tallying functions.
  • Via its integration with the Actions module, it can trigger workflow steps whenever votes are casted and results are tallied, such as promoting a node to the front page, hiding a comment flagged as spam, or sending some eMail.
  • It integrates with the Views module, which allows for slice and dice of the content of a site based on user consensus. And tt provides functions to format vote data to display them to users.

Typical rating related modules with a stable release for D7:

Views / Rules / Flag / Message

Everything above relates to "Rating" (or voting). Some more modules that you may want to consider (= add to the mix of modules you might want to consider):
