Pagrindinė problema yra ta, kad norint siųsti duomenis į išorinį raktą, reikia naudoti POST metodą.
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>
Šis kodas apibrėžia du modelius, Model1 ir Model2, ir serializatorius, skirtas Model2.
Model1 turi lauką pavadinimu name.
Model2 turi lauką pavadinimu name, ir svetimo rakto laukas vadinamas model1. Užsienio raktas susieja su Model1.
Serializatorius, skirtas Model2Serializer, apibrėžia, kurie laukai turi būti įtraukti konvertuojant modelį į JSON formatą. Šiuo atveju tai apima šiuos laukus: 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.
