Python: Debugging/Developing SMTP mail things

You often have 'situations' when you developing Contact forms, or any other forms which have to send emails with python. You have to install or have working SMTP server on your Dev machine like say 'monstrous' Sendmail or something like it. It can cause errors in Django/Python like [Errno 61] Connection refused:


[Errno 61] Connection refused


But python has it handled for you. Python's standard distribution has a test SMTP server that you can test sending mail with. It actually does not sends anything. But you can examine outgoing email message like you've actually send it.
Type something like:


python -m smtpd -n -c DebuggingServer localhost:1025


It will start a command line server on this console and it will print everything your server should send through SMTP.
Also make sure to modify mail sending code to use your non standart port number like so:


server = smtplib.SMTP(SERVER, 1025)
server.sendmail(FROM, TO, message)
server.quit()


Or with 'sudo' (if you have admin permissions) you can start a test SMTP server like you are actually using sendmail simply changing port number of your server.  Or just change 1025 to 25 (SMTP default port) if you are working under root permissions user. Like so:


sudo python -m smtpd -n -c DebuggingServer localhost:25


Found interesting? Have a better/simpler way or I am wrong?

    If you want to read html emails or simply se your email in a decent interface, you can use PyLocalSmtp, a web interface that uses the core python DebuggingServer https://pypi.python.org/pypi/pylocalsmtp/1.0.0

Pretty git Log

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...

Django: Resetting Passwords (with internal tools)

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_...
