The main problem is that you need to use the POST method to send data to the foreign key.
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>
This code defines two models,
Model2, and a serializer for
Model1 has a field called
Model2 has a field called
name, and a foreign key field called
model1. The foreign key links to the
The serializer for
Model2Serializer, defines which fields should be included when converting the model to JSON format. In this case, it includes the fields:
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:
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.
