Here is my model:
class Movie(models.Model):
name = models.CharField(max_length=800, unique=True)
imdb_rating = models.IntegerField(null=True)
movie_choice = (
('Act', 'Action'),
...............
)
movie_type = models.CharField(max_length=3, choices=movie_choice)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
class Hiren(models.Model):
movie = models.ForeignKey(Movie)
watched_full = models.BooleanField(default=True)
rating = models.IntegerField()
source = models.CharField(max_length=500, null=True)
watched_at = models.DateField()
quality_choice = (
('HD', 'HD'),
..............
)
video_quality = models.CharField(max_length=3, choices=quality_choice)
created_at = models.DateField(auto_now_add=True)
updated_at = models.DateField(auto_now=True)
and my serializer:
class MovieSerializer(serializers.ModelSerializer):
class Meta:
model = Movie
fields = '__all__'
class HirenSerializer(serializers.ModelSerializer):
movie = MovieSerializer()
class Meta:
model = Hiren
fields = ('movie', 'id', 'watched_full', 'rating', 'source',
'video_quality', 'watched_at')
def create(self, validated_data):
movie_data = validated_data.pop('movie')
movie = Movie.objects.create(**movie_data)
hiren = Hiren.objects.create(movie=movie, **validated_data)
return hiren
def update(self, instance, validated_data):
print('hit') # doesn't print anything on put type request
movie_name = validated_data.get('movie', {}).get('name')
# print(movie_name)
# print(instance.movie.name)
if movie_name != instance.movie.name:
instance.movie.name = movie_name
# instance.movie.name = validated_data.get('movie', {}).get('name')
instance.movie.imdb_rating = validated_data.get('movie', {}).get(
'imdb_rating')
instance.movie.movie_type = validated_data.get('movie', {}).get(
'movie_type')
instance.watched_full = validated_data.get('watched_full', instance.
watched_full)
instance.rating = validated_data.get('rating', instance.rating)
instance.source = validated_data.get('source', instance.source)
instance.video_quality = validated_data.get('video_quality',
instance.video_quality)
instance.watched_at = validated_data.get('watched_at', instance.
watched_at)
# instance.movie.save()
instance.save()
return instance
When I try to update the data without changing the "name" its throws an
error:
{ "movie": { "name": [ "movie with this name already exists." ] } }
So I try to fix this via those lines:
if movie_name != instance.movie.name:
instance.movie.name = movie_name
But it turns out that put request doesn't hit the update method at all.
