Report Field: represent a number, a calculation unit, for example: a Sum of a certain field. The report field identifies how the calculation should be done. ResultFields can depend on each other.
Generator: Represent a concrete report structure.If it would group by certain field, do a time series or a cross tab, and which columns (Report Field) to be calculated. It’s also responsible for computing and provides low level access. ie you can get the data in a list of dict/objects
View: Responsible for creating a nice form to filter the report on, pass those filters to the generator class to create the report. It mimic the Generator API. Provide high level access. You can hook it to your urls.py and you’re all set, with the charts.
