Hi, It’s a bit more complex than that.
Content négociation along with renderers and parsers will move the data from the HTTP body into basic python types (int / floats / strings). Serializers will move those basic types from and to more complex ones (DateTimes, Decimals, Django models / querysets). hopes this will help.
