Peewee ManyToMany关系的中间表上的额外字段

Question

我试图通过Peewee 3.2.2中额外列的中间表建立多种关系，如下所示：

ThroughDeferred = DeferredThroughModel()

class Playlist(BaseModel):
    ...
    movies = ManyToManyField(Movie, backref='playlists', through_model=ThroughDeferred)

class Movie(BaseModel):
    name = CharField(max_length=100)

class PlaylistMovie(BaseModel):
    playlist = ForeignKeyField(column_name='playlist_id', field='id', model=Playlist)
    movie = ForeignKeyField(column_name='movie_id', field='id', model=Movie)
    position = PositiveSmallIntegerField(default=1)

    class Meta:
        table_name = 'playlist_movie_relation'

ThroughDeferred.set_model(PlaylistMovie)

然后，在查询时我得到的是没有位置的相关电影数据列表。

list(playlist.movies.dicts()) 
> [{name: 'blah', id: 3}, ...]

如何获取playlist.movi​​es中的位置数据？

Answer 1

这应该有效：

bot.on('callback_query', function onCallbackQuery(callbackQuery) {
    if(!didWeRemoveHisKeyboard(callbackQuery.from.id))
        removeHisKeyboard(callbackQuery)
    //then handle the user response
})

removeHisKeyboard = function(callbackQuery){
    bot.editMessageText(callbackQuery.message.text,
    {message_id:callbackQuery.message.message_id , chat_id:callbackQuery.from.id,
    reply_markup: {
        remove_keyboard: true
    }}).catch((err) => {
        //some error handling
    }).then(function(res){
         if(res)
             addThisChatToHandledList(callbackQuery.from.id)
    })

}
