可以访问序列化程序验证的数据DRF

Question

all the django rest framework docs assume your going to instantly save the data. But what if I want access to the serializer data? What if I want to do something with it. Or if the serializer contains info other than what I need to save in a model?

is the validated_data attribute what we need?

So

validatedData = serializer.validated_data
userid = validatedData.get('id')

would work right?

Answer 1

Yes you are right, but remember the validated_data is generate only after you call .is_valid() method. For example:

serializer.is_valid()
# do it first ^^^^^
validatedData = serializer.validated_data
userid = validatedData.get('id')

You can look on example saving-instances in the docs
