Основният проблем е, че трябва да използвате метода POST, за да изпратите данни към външния ключ.
I have a model with a foreign key. I am trying to post data to this model using the Django Rest Framework. How do I post data to the foreign key?
<code>class Model1(models.Model):
name = models.CharField(max_length=100)
def __str__(self):
return self.name
class Model2(models.Model):
name = models.CharField(max_length=100)
model1 = models.ForeignKey('Model1', on_delete=models.CASCADE, related_name='model2')
def __str__(self):
return self.name
class Model2Serializer(serializers.ModelSerializer):
class Meta: # noqa: D106,D205,D400,E501 # pylint: disable=too-few-public-methods,missing-docstring,line-too-long,no-init # noqa: D105 # pylint: disable=R0903 # noqa: D102 # pylint: disable=R0901
model = Model2
fields = ['id', 'name', 'model1']
</code>
Този код дефинира два модела, Model1 намлява Model2, и сериализатор за Model2.
Model1 има поле, наречено name.
Model2 има поле, наречено nameи поле за външен ключ, наречено model1. Външният ключ се свързва с Model1.
Сериализаторът за Model2Serializer, дефинира кои полета трябва да бъдат включени при конвертиране на модела във формат JSON. В този случай той включва полетата: id, name, and 'model1'.
Save Foreign Key Using Django Rest Framework
In Django, you can use the save_foreign_key() function to save a foreign key in a model. This function takes two arguments: the model name and the name of the column in the model that stores the foreign key.
To save a foreign key in a model named "MyModel", you would use the following code:
save_foreign_key("MyModel", "id")
What is Foreign key
A foreign key is a column in a table that references a column in another table. When you insert data into the table, Django automatically creates the foreign key for you.
