Goodreads_rating DEPRECATED

[thekidsmom]

Just recently, I received this error message: 'could not convert string to float: #3.36'.

I thought an update would help, but sadly it did not. Any help would be greatly appreciated as I use this plug in all the time!

The full error log is:

According to the error Maniattico mentioned tearlier, he error could be related to the publishers name with any of these characters: á, é, í, ó or ú

Maniatticco did not share the solution and I dont know any Publisher with th one of these characters. I do not use goodreads by myself.
Can you give me the name/author or ISBN of the book that produced the error, so I can take a look.

[thekidsmom]

All of the books I downloaded from Amazon after July 22 are returning this error message. For example; Fashionista by Vanessa McKnight.

And I checked the publishers for all those books....they are from a myriad of publishers.

Thanks for your brain power!

[thekidsmom]

I noticed something when I was focused on the publisher field.

Now, the publisher field has info that looks like this: MIRA#Pr.Barnart#4.06.

Prior to the 'problems' it would like like this: Amazon Digital Services (or whatever the name of the publisher is).

Hey,

I have made an update: frating 0.2.2 for dealing with special characters in the name of the Publisher.
In the starttopic of this thread you will find an attachment frating2-2.zip.
Just manual install this plugin en restart calibre. The goodreads file is still unchanged ( Yeah I know there is a newer version of goodreads )

Enjoy.

This idea may not be possible or just beyond the scope of this plugin.

If you have the rating working and have a way of marking books as read/not-read. Can you use the ratings to recommend a book.

Concept:
using a temp variable. Sum the ratings of the books not read.
get a random number between 0 and the sum.
Add up the sums to find which book that random number represents. Jump to that book.
(this way you are 5 times as likely to get a 5 star recommendation then a one star recommendation).

Have a method to indicate you don't want that book. Repeat until it recommends a book you want to read.

Varient 1: Use the cube of the ratings. I would much rather read a 5 star book then a one star book. By cubing the ratings, I am 125 times more likely to get a 5 star book recomendation.

Varient 2: For books that dont have ratings, is it possible to use the average of the other rated books by the same author? Or if no rating by the author, have some method of noting and favoring award winning authors.

Varient 3: Have 2 ratings fields. The first is to store ratings from Goodreads or amazon. The 2nd, duplicates the first is available. The average of other books by the same author if available. Add one if it is an award winning author if known. Or use a default of 2 for an unrated book (even an unknown book is better then a book with a rating of one). Use the 2nd rating to select random books. The user should be able to enter ratings into the 2nd field, so that if he reads one good book by an author and rates it, then it will recommend more books of that author.

I do something like this in a spreadsheet. It would be nice is Calibre could do something like it.

Beautiful! It works perfectly. Thanks so much for your efforts and time!

I realized today that when choosing metadata sources, it's helpful to have ONLY the goodreads source chosen (ie not Amazon too). When I had both Goodreads and Amazon chosen as metadata sources, the rating wasn't always coming through.

[JSWolf]

If a book is new enough, the ratings from Goodreads are 100% worthless as a lot of people rate books before they are even released and have not yet read them. So what you get is ratings based on their expectations and not based on reading. So I would say give it a year after release to get things sorted.

Is anyone having problems with this plugin not returning decimal ratings? Just recently I've been getting 0 results. Error log is here (any advice appreciated!):

If you read the message, it isn't to do with the rating being a decimal. The error states that it didn't find any books.

The problem is that the search results page changed recently. The plugin needs to be changed to match. It's probably the same change that I made recently for the Goodreads metadata source plugin.

You are right. Goodreads is very much based on the goodreads plugin from Kiwidude/Davidfor. The previous version was based on goodreads 1.1.8.
I adjust the goodreadsX to the latest version 1.1.11.
You can find it (goodreadsX 0.2.1) at the start of this thread or right under this text.

GoodreadX is not a plugin that is presented within Calibre.
You have to do a manual install through load by file in the preference section.
As far as I can see, you can just use load by file, the previous version will be overwritten. But if you are not sure,you can first delete the older version and then install the new one.

It is ment for use in combination with frating ;-)

[thekidsmom]

@Pr.BarnArt--as always, you are super helpful and speedy too! I really do appreciate your efforts. I use this at least 3-4 times a week and love the feature.

Thanks for your positive words and for helping someone with very little coding knowledge (as in none) understand how to move forward. The file works as you stated--a simple overwrite did the trick.

Have a great weekend.

[Rellwood]

I am wondering why the rating has to come from the Publisher. I know that when I export my GR shelves the average rating is listed. I have been doing that since I have had Calibre, and it sucks to do because it requires me matching all those books and making sure the field is empty to start...

[mariaclaudia]

This is a very usefull plugin for me. However, looks like it's only work if Calibre set in english languaje, because when I use with spanish, nothing happend after I use frating for set decimals, but if I use english, all looks fine.

Sorry my grammar
