Hierachical tags in opds feed

At_Libitum · 10-08-2013, 09:48 PM

Hi,

I am not sure where to post this so feel free to move if incorrectly posted.

I seem to have stumbled over a problem but am not sure where the cause may lie.

I have a custom column #subgenre which is build from two other columns

the first is again a custom column #collection and the second is the tags column.

content of these two columns is joined using this pattern

#collection.#subgenre

if #collection contains more than 1 entry these are concatenated again using a period as separator.

For every entry in tags, whatever comes out of #collection, is prefixed to each tag.

Works like a charm in the tag browser, but not in the OPDS feed.

for instance. one such a #subgenre is present in the feed as follows

Code:

  <entry>
    <title>Classics</title>
    <id>calibre:category:Classics</id>
    <updated>2013-10-09T08:46:02+00:00</updated>
    <content type="text">5 books</content>
    <link href="/stanza/category/2373756267656e7265/49436c6173736963733a2373756267656e7265" type="application/atom+xml;type=feed;profile=opds-catalog"/>
  </entry>

And this happens to be a simple one, no tags present and just the one #collection entry.

so when I try navigating to the link to show me the 5 books , I get this.

Code:

GET /stanza/category/2373756267656e7265/49436c6173736963733a2373756267656e7265

There is a bug in OPDS where categories made from composite columns don't work. I have submitted changes to fix it.

Thanks for the update and compliments on being able to identify it even with that mangled report. Post is fixed now.
