575992 - Ratings widget should use average_rating

Status: RESOLVED FIXED

(addons.mozilla.org Graveyard :: Public Pages, defect)

Description

[Wil Clouser [:clouserw]]

Looks like the ratings widget is using bayesian_rating right now - it should use the average_rating.

Comment 1

[Jeff Balogh (:jbalogh)]

Should that happen in listings as well, where we are sorting by bayesian rating?

Comment 2

[Wil Clouser [:clouserw]]

The idea is to use the bayesian rating when comparing against other add-ons (eg. search listings) and the average rating when displaying something on the page.

If my memory serves me right, we implemented this functionality to avoid addons being ranked top if they had a single 5 star review.

The URL in comment 4 was showing 4 stars, it should show 5 after this goes out.

It ate my comment when I duped I guess.  Anyway, you can see this fixed at https://preview.addons.mozilla.org/en-US/thunderbird/addon/58857/

This add-on appears to be still experiencing this bug: https://addons.mozilla.org/en-US/firefox/addon/6584/
I think mine as well: https://addons.mozilla.org/en-US/firefox/addon/7684
They were both 5 stars before this bug appeared.

Were there any changes in the way the star count is generated?

There haven't been any changes to the calculations.  If there is a bug, it's not this one.

As a developer of addons.mozilla.org/en-US/firefox/addon/6584
I can said that it's unfair for addons that have 4.5+ rating than 4.5-
 
I think it's wrong calculations 
because there's no difference between 4.1 and 4.8 (this rating earn much harder rather 4.1) rating for regular users, because they'll see 4 star. 
So you need to implement "half-start"

You can go google ant type for example "buy barebone computer"
and under some payid ads you can see rating. And there're different start 
on 4/6  4/8/ 5/0

Because I don't see any point to make my addon better to earn 4/8 because users will see only 4 stars. And developers who have 4/1+ rating do much less for their addons.

Hope you understood my point. 
Sorry, English isn't my native language :)

If your addon had a rating of 4.5+, it would be shown with 5 stars.  We already round ratings on the backend before showing the stars.
