HOPE FlexFields
This library provides the ability to define a set of fields and related validation rules dynamically. It has been designed as part of the HOPE project to manage user-customizable fields (FlexField). The idea is to have a central business logic repository for data import validation.
It provides four classes:
- FieldDefinition: This represents a collection of reusable pre-configured fields
- FlexField: Instance like representation of
FieldDefinitioninside aFieldset - Fieldset: Group of FlexField
- DataChecker: Compound of fieldset
From the design point of view a high level comparison with Django components could be:
FieldDefinition=class forms.FieldFieldset=forms.FormFlexField=forms.Field()DataChecker=[forms.Form(),...]
... and some utilities
- Automatic creation of FieldSets inspecting exiting models
- Automatic creation of XLS file matching an existing Datachecker
- Validate XLS against an existing Datachecker
