We always write something unusual while doing basic things. Our own bicycles and crutches to work out some unusual situation. Here is another recipe to do a thing like so. I have tried several libraries and readymade decisions. But it assumes you have them installed. And you often try things in console, don't you? Anyway the recipe is simple and quite straightforward. import datetime # Getting first timestamp t1 = datetime . datetime . now ( ) # Your function e.g.: data = [ g . name for g in request . user . groups . all ( ) ] # Second timestamp t2 = datetime . datetime . now ( ) print "Execution time: %s" % ( t1 - t2 ) It is rude and quite simple but may often suit you well to measure execution time in a simple and straightforward manner. Also nice idea to write down this function into logs. It may be handy on refactoring of your core app for e.g.; import datetime import logging log = logging . getLogger ( 'mylogger' ) # Getting ...

I have had a task recently. It was about adding a forms/mechanism for resetting a password in our Django based project. We have had our own registration system ongoing... It's a corporate sector project. So you can not go and register yourself. Admins (probably via LDAP sync) will register your email/login in system. So you have to go there and only set yourself a password. For security reasons you can not register. One word. First I've tried to find standart decision. From reviewed by me were: django-registration and django password-reset . These are nice tools to install and give it a go. But I've needed a more complex decision. And the idea was that own bicycle is always better. So I've thought of django admin and that it has all the things you need to do this yourself in no time. (Actually it's django.contrib.auth part of django, but used out of the box in Admin UI) You can find views you need for this in there. they are: password_reset password_reset_...

I like to invent bicycles in my code. They often come in handy and you basically do not rely on Django version... So upon updating your project's Django version in future times you will not have to refactor half of all the code. So... How do you test http redirects? I usually restrict my time in thinking and write code like if redirect target is hardcoded. And it really is in most of the times. But imagine if you decide to redirect your view response in several places. Or imagine if you're not the only one who owns you'r project's code and there are many collaborators that can change things without warning... And you need to have a test for that view that will test redirects and complex code behavior. I used to check redirects like so: response = self . cliet . get ( '/myview' ) self . assertEqual ( response . status_code , 302 ) # View redirected... All ok... But  if you have some view that can redirect to things that you need to check. How would y...

There are lots of occasions when you want to be private in the net. Now it's common to say "Anonymous". Many people do not even think it's important. I, personaly, dislike facebook, skype, twitter, any else third party... having my contacts list synched to their server without even telling me...  I do not want to be truly anonymous, you know... Have nothing to hide really. But I want that really smal confirm that Skype, for e.g. would take my contacts and for what reason.  Facebook was first, as usual... They've done it. I really deleted their app from my iOS devices first. But instead of taking lessons from their mistakes... All huge companies gone wild about this possibility to copy some new ammount of user data... Skype was second (for me)... Then LinkedIn... However they warned and I've agreed... So nothing really bad to say about them. But MS is such a Microsoft... They want me to "skype" instead of "calling" my friends through ...

I had a problem "Unauthorized" in official twitter client for Mac. Tried several instal/reinstall. Deleted/Downloaded again from Apple App Store. It all didn't help. They seem to change something in authentication. So I've tried deleting all the config files in ~/Library/ Main solution that helped me: 1. Switch off the client. (be sure to Close an app) 2. Delete: ~/Library/Preferences/com.twitter.twitter-mac.plist.lockfile ~/Library/Preferences/com.twitter.twitter-mac.plist 3. Launch Twitter app and login from scratch. I have revoked access this twitter client too in my https://twitter.com/settings/applications  but it seem to make no effect. Making similar actions to TweetDeck for Mac does not help. So it seems like problem is somewhere deeper. Hope it will help you solve similar issue.

Django supports security models and methods out of the box. They are Group and Permission objects. Permission is m2m related to internal Django User. I helps you relay on request.user later in your code. You often come to situations where you may need a view to be accessed only by certain group of users.  For example you have the app that has two groups of users. One can search and another one can Index files. Simplest approach is to use Groups here.  In fact you may use permissions in case your app will have several unique users that might do some stuff. In general best approach is to use Group to specify type of users and Permission to specify the role of users in this group. So if you will have Group called 'search' and it will have permission with name, say 'search stuff'. So when you will call: def my_view (request): # ... my view actions ... user_permissions = request.user.user_permissions.all() for p in user...

SO you dislike git log output in console like me and do not use it... Because it looks like so: How about this one? It's quite easy... Just type: git log - - graph - - pretty = format : '%Cred%h%Creset -%C ( yellow ) %d%Creset %s %Cgreen ( %cr) %C ( bold blue ) <%an>%Creset' - - abbrev - commit - - It may be hard to enter such an easy command every time. Let's make an alias instead... Copypaste this to your terminal: git config --global alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --" And use simple command to see this pretty log instead: git lg Now in case you want to see lines that changed use: git lg - p In order for this command to work remove  the -- from the end of the alias. May the code be with you! NOTE: this article is a rewritten copy of  http://coderwall.com/p/euwpig?i=3&p=1&t=git   and have b...
