Best Django design with constant updating data
I’m making a website with Django framework with MySQL for database to display some data (e.g. daily stock prices for many stocks). Everyday, I would like to refresh all the data in the database to the latest data. There’s a lot data so I want to replace the entire database instead of inserting new entries. Is there an elegant way of achieving this? Is this kind of operation supported by relational databases like MySQL. Thanks! -

Django question: Approval Form: Should I use DetailView of UpdateView?
A newbie question - I am stuck in dilemma between using DetailView or UpdateView in Django The scenario: A "request" object (e.g. requestor, date of request, status, etc.) is sent to an "approver" for an approval. The approver can either reject or approve the request, as well as enter their comment in a comment field. The form should display all the fields from the request object, but the approver should only be able to update the comment field and then click either on "Approve" or "Decline" buttons in a form (so POST method is required) Based on my current knowledge, I think I can hack the problem but I am looking for a "proper way" to design this type of requirement. I don't want to use readonly or disabled attributes approach, because I've tried it and fields can still be changed / navigated to on the screen - even though they won't be saved in the database. -
