Changing the rating of songs

Hello, this is my first day coding a component for foobar

I cant find informations about how to change the rating field of a track. Here is the code I wrote

static_api_ptr_t<playlist_manager> _pm;
t_size _pl = _pm->get_active_playlist();
metadb_handle_list _its;
_pm->playlist_get_selected_items(_pl, _its);
if(_its.get_count() > 0){
   MessageBeep(MB_OK);
   for(t_size i=0; i<_its.get_count(); i++){
      _its.get_item(i)->
   }
}

Here is the interesting part:
_its.get_item(i)-> ...
how to change the rating for this item ? Can anyone help ?

Thanks in advance

There is no method on metadb_handles for setting tags and the foo_playcount component does not provide an API through which you could set the rating. You could execute the context menu command from foo_playcount, but doing that programmatically is a bit of a challenge.

I see, here is the incomplete command that I think I should use:

menu_helpers::run_command_context(standard_commands::guid_context_save_playlist, standard_commands::guid_context_save_playlist, _its);

But I need to replace "standard_commands::guid_context_save_playlist" with the GUID of the "set rating to 1"
I can't find in the documentation that GUID... can you please help ?

Thanks

I've been looking into the exact same problem. What I'm doing until now is

Code: [Select]
GUID command,subcommand;
bool result=menu_helpers::find_command_by_name("Playback Statistics/Rating",command);
result=menu_helpers::run_command_context_playlist(command,subcommand);

Unfortunately, find_command_by_name() doesn't seem to work for context menus which have more than two levels, i.e. calling it with "Playback Statistics/Rating/1" does not work. So I only have the GUID of the "Rating" menu (15D9655C-F6DE-4B98-8942-A9DAE2F9AD75), but not the one of the "1" action.

That GUID is not part of the documentation of foo_playcount. Strictly speaking it is an implementation detail. However since changing it would also invalidate keyboard shortcuts for that command, it is safe to assume that it will stay fairly stable.

The problem is that this helper function will not find dynamic menu commands, i.e. commands with a non-null subcommand GUID. (By the way, you'd better initialise that subcommand variable there. Use pfc::guid_null if you don't have a concrete subcommand GUID.)

Oh, I wouldn't have expected the Rating submenu to be dynamic. The content seems pretty static to me. Well, anyway, so how do I find out the GUIDs of the "1" ... "5" subcommands so I can execute them programmatically?

Sure! That was just some example code and I left the subcommand variable uninitialized to indicate that I don't know what to fill in there.

Thanks!

Thanks its working
By using this:

if (!find_context_command_recur("1", dummy, cm->get_root(), node))

for "set rating to 1"
That's not really clean, as there might be others actions in the futur labeled "1", but it does the job

Please don't ever release or redistibute anything containing such horrible hacks.
Stay sane, exile.
