Calibre: TypeError:expected string or buffer
So, I've just had upgraded to Calibre's recent 0.7.21 version. In previous version I set up some custom column, and had no problem so far.
But after upgraded, when I tried to click one of my book which is in custom column it show error: Code:
ERROR: ERROR: Unhandled exception: <b>TypeError</b>:expected string or buffer Traceback (most recent call last): File "/home/kovid/build/calibre/src/calibre/gui2/library/models.py", line 366, in current_changed File "/home/kovid/build/calibre/src/calibre/gui2/library/models.py", line 342, in get_book_display_info File "/home/kovid/build/calibre/src/calibre/ebooks/metadata/book/base.py", line 451, in format_field File "/home/kovid/build/calibre/src/calibre/ebooks/metadata/book/base.py", line 477, in format_field_extended File "/home/kovid/build/calibre/src/calibre/utils/date.py", line 148, in format_date File "/usr/lib/python2.6/re.py", line 151, in sub return _compile(pattern, 0).sub(repl, string, count) TypeError: expected string or buffer Basically it kind of prevent me to see the book in booklist view (although I still can the metadata). If anyone can explain why this is happened, much appreciated. |

Check the format section of that custom column to be sure that it contains only characters. To check the format, right-click on a column header, choose 'Add you own columns', select the date column, and press the circle-I button.

I'm not sure what you mean. Do you mean it's the heading column? Anyway I insert screenshot from my column setting:

Thanks. Found it.
As a work-around, put something in the 'Format for dates' box. Put the default in if that is what you want. |
