Found a workaround.
the field get_value uses the self.fieldname, in this particular specific
case i dont want that.. i want it to get the value from the source (json)
```
class BaseExtractDataFromJsonField(serializers.Field):
"""
Instead of using the field_name, for the value rather use the source
as then we can massage ugly json data
"""
def get_value(self, dictionary):
if self.source not in dictionary:
if getattr(self.root, 'partial', False):
return serializers.empty
# We override the default field access in order to support
# lists in HTML forms.
if serializers.html.is_html_input(dictionary):
return dictionary.getlist(self.source)
return dictionary.get(self.source, serializers.empty)
class CharField(BaseExtractDataFromJsonField, serializers.CharField): pass
class EmailField(BaseExtractDataFromJsonField, serializers.EmailField): pass
class DecimalField(BaseExtractDataFromJsonField, serializers.DecimalField):
pass
class IntegerField(BaseExtractDataFromJsonField, serializers.IntegerField):
pass
and then simply use the overridden CharField above..
