Dambudziko guru nderekuti iwe unofanirwa kushandisa iyo POST nzira yekutumira data kune yekunze kiyi.
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>
Iyi kodhi inotsanangura mhando mbiri, Model1 uye Model2, uye serializer ye Model2.
Model1 ane munda unonzi name.
Model2 ane munda unonzi name, uye kiyi yekunze yakanzi model1. Makiyi ekunze anobatana ne Model1.
Iyo serializer ye Model2Serializer, inotsanangura kuti ndeapi minda inofanirwa kuverengerwa paunenge uchishandura modhi kuita JSON fomati. Muchiitiko ichi, inosanganisira minda: 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.
