Help with extra metadata columns from metadata download plugin
Hi, I wanted to add extra metadata columns, when I'm downloading information in my metadata plugin, so that you can use that data in the book overview as a new column.
However, it is not working for me. Example. The extra data is 'original title', if you have translation in other language. So, what I did, I added it touched fields: ``` touched_fields = frozenset(['title', 'authors', 'identifier:martinussk', 'identifier:isbn', 'rating', 'comments', 'publisher', 'pubdate', 'series', 'tags', 'languages', '#original_title']) ``` Then I added the user's metadata information to the Metadata object, and set the value: ``` mi = Metadata(showing_title, authors) parsed_original_title = self.parse_original_title(root) mi.set_user_metadata('#original_title', {'datatype': 'text', 'name': 'original_title', 'is_multiple': False, '#value#': None}) mi.set('#original_title', parses_original_title) ``` So far so good, however, when the download is running, I'm getting this error: ``` calibre, version 5.34.0 CHYBA: Sťahovanie zlyhalo: Stiahnutie metadát zlyhalo. Detaily zobrazíte kliknutím na Zobraziť podrobnosti Traceback (most recent call last): File "calibre\utils\ipc\simple_worker.py", line 304, in main File "calibre\ebooks\metadata\sources\worker.py", line 107, in single_identify File "calibre\ebooks\metadata\sources\identify.py", line 498, in identify File "calibre\ebooks\metadata\sources\identify.py", line 366, in merge_identify_results File "calibre\ebooks\metadata\sources\identify.py", line 154, in finalize File "calibre\ebooks\metadata\sources\identify.py", line 248, in merge_isbn_results File "calibre\ebooks\metadata\sources\identify.py", line 350, in merge File "calibre\ebooks\metadata\book\base.py", line 163, in __getattribute__ AttributeError: Metadata object has no attribute named: '#original_title' ``` Looking at the base.py class, the merge does not merge any user_metadata. It has trouble doing that, as it tries to get the null value from the localy created Metadata object --> https://github.com/kovidgoyal/calibr...entify.py#L346 If I don't include the '#original_title' in 'touched_fields', then the download works, but the fields are not reflected inside the table. Where in the Settings->Add your own column-> I added a field with a lookup name: "#original_title". How is this supposed to work? If at all? Is it possible for metadata download plugin define custom columns that can be looked up in the 'Add your own columns' section? I saw several plugins just add this information to the 'comments' section. But is it possible in some way to have this as the actual column in overview? |
