python - Grouping Data by field in Django -

as chapters grouped season:

season 1: chapter 1 chapter 2 chapter 3 chapter 4

season 2: chapter 1 chapter 2 chapter 3

#models.py  class serie(models.model):     # optional fields      def serie_chapter(self):         return self.seriechapter_set.order_by("season","chapter")  class seriechapter(models.model):     serie = models.foreignkey(serie)     name = models.charfield(max_length=100, unique=true)     slug = models.slugfield(max_length=100, unique=true)     season = models.integerfield(db_index=true, choices=choices_season)     chapter = models.integerfield(choices=choices_episode)     created_at = models.datetimefield(auto_now=true) 

so, can add chapters per season?

thanks.

you can add 1 more class

class series_chapter(models.model):     series=models.foreignkey(serie)     chapter=models.foreignkey(seriechapter) 

in class seriechapter won't need

serie=models.foreignkey(serie) 

for season 1 want add episode1 , episode2 first add series , chapters in respective models. in series_chapter

s1c1=series_chapter.objects.create(series=instance_of_serie,chapter=instance_of_seriechapter)#for chapter 1 s1c2=series_chapter.objects.create(series=instance_of_serie,chapter=instance_of_seriechapter)#for chapter 2
