Expert DJANGO admin (AdminModel & forms & JS)

Si vous parlez francais couramment - c'est un vrai plus - précisez le moi ! --- On the django admin panel, I have a model (Company) that contains inlines (PricingPlan). I have 2 groups of admin users : superadmin (all access) and vendor (limited access) Each vendor is part of a model Vendor that has VendorPricingPlans. I would like to make the PricingPlan inline form dynamic based on : the user group (superadmin/vendor) and the Vendor object (if the user is part of group vendor) The inline form should have be mix of python django forms & javascript (to handle custom defaults value based VendorPricingPlans, and errors shown without clicking on the save button) Please explain me how you would deal about this issue ?
