Hello, django-users. I'm in need of some serious help on deciding how to design my next project. Below is my attempt to describe the use case:
*USE CASE* I'm writing an accounting app that will be generating unique monthly reports of the revenue results for a list of Accounts (model) in the company. Each Account has a set of instances of Entry (model) with a Decimal value, date and some text, as well as a FK to Account. These entries are uploaded through an (already coded) import function which parses a .csv and, using DSE, inserts 1.5 million rows to the Entry table. These entries also have an FK to Task (model) so I know which import process generated them. Each month I want to allow an admin to pick a set of Accounts to be displayed in the monthly report, which needs to be unique for obvious reasons. *CODE models.py *http://dpaste.com/hold/570933/ *example .csv file to be imported* (importing the file is already coded and works 100% so far)* *http://dpaste.com/hold/570934/* * *QUESTIONS* 1. Should I create another model named MonthlyReport with an M2M relation to Accounts, and then add an 'is_active' flag so I know which one is the official monthly report? 2. If so, how can I ensure there's only one official monthly report? Perhaps setting is_active to False to all the other MonthlyReports that carry the same month/year? 3. How should I prevent users from importing the Entries more than once? Forcing a deletion of entries for the same month as the imported entries is a possible solution.. The .csv file should always be restricted to a single month, but I guess I could write a check for that too, or expand the deletion for every matching month. As you can see, I have a few ideas on how to proceed, but it would be great if anybody could weigh in on this, as the deadline is incredibly short (1 month including views/templates, etc). I thank everyone in advance for reading through this and for any help they can offer. Cheers, André -- You received this message because you are subscribed to the Google Groups "Django users" group.
