I have a requirement, which is, show a model's OneToMany related model's fields in a page, the problem is, if I pass the main model to simple_tag, then using filter or get or whatever methods to lookup the specific related model, it will generate db query everytime. When I have 5 simple_tag which show fields for that related model, it query db 5 times. I can lookup this related model in view level, and pass it to template, but the code wasn't very nice. If I have 3~4 related models, means I must pass 3~4 more variables to template level. Is there a better design?
