python - Save object from template -

im creating music website. in website, add functionality of favorites users add songs favorite lists.

i have done don't know how save it. here code:

models.py

class song(models.model):      is_favorite = models.booleanfield(default=false)      def __str__(self):         return self.song_title 

views.py

def song_detail(request,song_id):     song = song.objects.get(pk=song_id)     favorite = song.is_favorite = true     return render(request, 'song_detail.html', {'favorite':favorite}) 

song_detail.html

<button onclick="{{favorite}}">favourite</button> 

while playing python shell, found problem: let s created song pk=1,

d = song.objects.get(pk=1) d.is_favorite=true d.save() y = song.objects.filter(is_favorite=true) print(y) ->s 

the problem after making song's is_favorite = true, need save it. don't know how implement in code such when user clicks button boolean field changes true. thank you.

i solved myself!

i changed values of favorite views song.update(is_favorite=true).
