This post shows some of what you would do in the template function. What is missing is that you can get arbitrary metadata items for a book from the kwargs parameter. For example, kwargs.get('series') will return the value of the series or None if there isn't one. Similarly, kwargs.get('tags') will return a list of tags on the book. You use the lookup name as the parameter for 'get'. From what I understand, you would want a different function in each library, but I am not sure of that.
You could do this in a general program mode template using in_list, list_union, and the like, but it would most likely be very slow. |
Okay, that kinda flew over my head (as did the example you linked to), sorry. Yes, I plan on using a different function for the different libraries but if I have an example for how to do it for one library, I think I'll be able figure out the rest.
For example, I have the following:
Code:
Title Series Tags
Harry Potter and the Philosopher's Stone Harry Potter [1.0] Fiction, Children, Fantasy
Twilight Twilight [1.0] Fiction, Paranormal
How do I create the following custom columns from the above?
Code:
Title #MySeries #Type #Genre
Harry Potter and the Philosopher's Stone Series: Harry Potter [1.0] Fiction Genre: Children, Genre: Fantasy
Twilight Series: Twilight [1.0] Fiction Genre: Paranormal
#MySeries: Basically exactly the same as series except with
"Series: " added to the beginning of the string.
#Type: If certain pre-defined values are in tags (
Fiction, Non-Fiction, Fanfiction, Magazine), it goes to this column.
#Genre: Basically all tags (excluding
Fiction, Non-Fiction, Fanfiction & Magazine) with
"Genre: " added to the beginning of string.
I'm trying to understand your sample code but as I'm a total noob to Python, I'm finding it quite difficult to comprehend.
