(i realise it's easiest define form hand, i'm curious how you'd that.) you override get_form() , , modify form change widget on password field: from django import forms class signup(createview): model = user fields = ['first_name', 'last_name', 'email', 'password'] def get_form(self, form_class): form = super(signup, self).get_form(form_class) form.fields['password'].widget = forms.passwordinput() return form b...

i have users table in database lay out : id username firstname lastname email photo as of now, since admin user have admin right , , can create, update, , delete. want allow users have same right me later on. before release feature, want keep track on edit - things doesn't lost, , it's keep history of things. what best practice feature ? know have programming logic in update function in controller function. know have create logs table on database store user_id : make change created_at : when change made old_data: string new_data: string for someone, had experiences feature, can please give me advice ? appreciate concern. thank you. i think best approach problem each action user takes want log should fire event. event::fire('some.event', array(auth::user())); then can register listeners each event , log appropriately. event::listen('some.event', function($user) { // create new item in logs table here. });

i noticing latency in rest data first time visit web site being served via azure mobile services. there cache or timeout of connection after set amount of time, because worried user experience while waiting 7-8 seconds data load (and there not lot of data, testing 10 records returned). once first connection made, subsequent visits appear load quickly... if don't visit site while, 7-8 seconds on first load. reason: reason latency "shared" mode . when first call service made, performs "cold start" (initializing , starting virtual server etc) described in question, after while when service not used, put "sleep mode" again. solution: if not want waiting-time, can set service "reserved" mode , forces service active time when not access while. aware requires pay fees.
