Tip : Custom Book Rating

[kamowski]

1) I want to assign my own book rating
and/or
2) I want to mark a book as important or significant.

---

1) Built-in Rating System:
- The default rating in "Calibre" is tied to the "author", not the specific book.
- If I add a "star" to a book in my library, it also contributes to the author's rating.
- This is actually a great feature—it helps me find books I've enjoyed.
- The fact that it also affects the "author's rating" is not a problem.
- For "requirement #1", this built-in system is sufficient.

---

2) Custom Column for Book Importance:
- If I want to "mark a book as important", the built-in rating isn't enough.
- A solution is using a "Custom Column", which can actually combine both needs.

---

"Preferences:" > "Add a custom column" > "+"

Quick setup: Choose "Rating"

Enter "Lookup name" and "Column header"
I set "VIF - Very Important File"


> Move the column "before Author"

> "OK > Apply > Restart"

---

> Preferences > "Look & Feel" > "Column Icons" > "Add Rule"

Set: "Icon without text", VIF (#myrating), and add an icon (see attachment)

New icon: "Exclamation mark (!)"
Condition:
Column: VIF
Value: Equals 5

*the icon only appears at 5 stars* !!!

> "OK > Apply > Close"


---

"Now I can assign my own ratings in the new column!"

"At exactly 5 stars", the exclamation mark appears

The new "VIF column" is visible in the left panel

I can "customize its icon"

My "own rating appears"

And of course, it is also visible in the column if expanded

---

On "image #8", this is the current condition setup—adjust it or add more rules as needed!

Huh! on your view of the built in rating being per Author.
Have you looked at the structure of metadata.db? (with a SQLlite db browser)
The Rating table is tied (linked) to the BOOK ID, Not Authors.

As to rating source Priority.
If there is a calibre rating inside the book
eg

 <meta name="calibre:rating" content="6.0"/>

That is used at the time of ADD Books.
If you Download Metadata in the MDE, It depends on How you have that Configured. That can have the top level set to accept any or the individual sources can be set (cherry pick by source)

As to Priority. I thought that was what Reading list PI did (I don't use that or even worry. I have a TBR list longer than my lifetime. YMMV )
