How to sort "based on..." collection?

[gitttt54]

Hi,

when creating "based on..." collections, they don't sort like I'd want them to sort. (title sort)

In Plex, they show up like "!085_Based on a Video Game" on sort-title. but thats not what I'd like to have.

As you can see in my config, I unsuccessfully fiddled around, but can not get the sort_title to be "+++05_06...something".

The wiki does not offer any helpful examples to me and the Community-Configs seem not to use it either.

Would anyone be so kind and point me on how I can get my own sort_title instead of the one Kometa automaticly sets?

Thank you.

templates:
  basedBla:
    sort_title: +++05_6_TEST_<<collection_name>>
    # collection_order: custom

libraries:
  Filme:
    library_name: Filme
    collection_files:
    - default: based
      template: basedBla
      template_variables:
        sort_title: +++05_6_ANOTHERTEST_<<collection_name>>
        collection_mode: hide
        sync_mode: append
        smart_label: random
        collection_filtering: user
        limit: 500
        use_separator: false
        style: diiivoycolor

That template stuff you have in there doesn't belong in config.yml.

Seems like there might be a bug here in the sort titles for that default.

Well... I tried hard, but I can't get any helpful info from the wiki regarding the config: https://kometa.wiki/en/latest/defaults/both/based/?h=based

I use

   collection_files:
   - default: based

so where should I put the template stuff instead?

Well... I tried hard, but I can't get any helpful info from the wiki regarding the config: https://kometa.wiki/en/latest/defaults/both/based/?h=based

The template variables that are available to that default are listed on that page.

    - default: based
      template: basedBla               # 'template' not valid in config.yml
      template_variables:
        sort_title: +++05_6_ST_<<collection_name>>
        collection_mode: hide
        sync_mode: append
        smart_label: random            # not a valid template variable
        # smart_label: release.desc    # not a valid template variable
        # sort_by: random              # not a valid template variable
        # sort_by: title.desc          # not a valid template variable
        collection_filtering: user     # not a valid template variable
        # limit: 500
        limit: 5
        use_separator: false
        style: diiivoycolor            # not a valid template variable in this context

I don't think collection_name is valid in the sort title. I think you may want title based on the default value shown in the wiki:

sort_title | Description: Changes the sort title of all collections.
Default: <<sort_prefix>><<collection_section>><<pre>><<order_<<key>>>><<title>>

libraries:
  Kometa-Demo-Movies:
    collection_files:
    - default: based
      template_variables:
        sort_title: +++05_6_ST_<<title>>
