I have a many-to-many relationship between 'Company' and 'Index', defined in an association table (CompanyIndex). Schemas below:
Company: (companyID, companyName, ...) Index: (indexID, indexName) CompanyIndex: (companyID, indexID, eventDate, eventType) Would like to provide a function on company to return index membership given a date i.e. company.indices(date) ==> index collection Would further like the collection (returned by the company.indices method) to create an entry in the association table on del or append of an index object. This would of course require the collection to be aware of existing indices, and not write a row for existing relationship (i think there is a pattern for this on the wiki). Am I biting of more than sa can chew? Should I implement this in some other, more app-specific way?
