I have a Schema as below:
from marshmallow import Schema, fields
class ContactSchema(Schema):
# ... other fields ...
phone = fields.Str()
# ... other fields ...
However, JSON data I deal with is different:
{
// ... other data ...
"information": {
"address": "foo",
"email": "[email protected]",
"phone": "+101234567890"
}
// .. other data ..
}
As you can see, phone key is under information, which is different than how ContactSchema is formed.
Can I, and how can I, map a Field under a Schema to a different path in target JSON data?
You can extend your schema and provide a pre_load method:
class ContactSchema(Schema):
@preload
def extract_information(self, data):
# Please check for None's
data['phone'] = data['information'].pop('phone')
return data
