DB Design question
Hi all! I have to store spreadsheet info on a db. Some kind of quotes where the user can store distinct prices for every zone. After modeling the data, i have a Cell like row. (related to a zone, and with a quantity field).. something like: zone1 1 100 zone1 2 99 zone1 3 98 Every zone is a fk... The problem is, that data grows quick.. because some quotes can have up to 65 unit fields with 70 to 100 zones.. Currently i have a autopk field. but I'm not sure if it will scale.. If i have 5000 users and every users makes 100 quotations.. (7000 rows on the worst case) this is 35.. easy enought to get out of autoincrement fields.. I'm thinking on getting rid of the pk field, and use a unique together with (zone_units). do you think this is a good aproach with the orm? I saw that is not possible to make primary key fields ( with grouped fields), but perhaps I can do it with instead of declaring a int field, have a char field storing the %s_%s_%s ( quote_id, zone_id, units ) ... do you think the last could be a good aproach? Sure if i have to shard the data (on the future) I can do it, using this kind of keys.. Data will be queryed by zone.. (For making comparasions of quotes) I will apreciate any help on the matter. -- You received this message because you are subscribed to the Google Groups "Django users" group.

BaseListView's get_context_data is missing kwargs?
Not sure if i'm understanding what are you saying. But kwargs on get.. Are stored on a object property.

Re: Restricting CreateView
I think you don't need extra packages for the task. You can overwrite the dispatch to validate permissions on get and post create view. -- You received this message because you are subscribed to the Google Groups "Django users" group.
