How to undelete a file in svn

Look in the .svn/entries file for the URL of the repo. Get the number of the last revision the file was in before you deleted (or if you don’t know, start from the current one and work backwards) svn cp -r <rev> <repourl>/<filename> ./<filename> Then commit.

Migrating sequences to Postgres

When moving a database from mysql to postgres, it’s often necessary to reset the sequences (.i.e. autoupdated row ids) Find out what the largest one is with select max (id) from mytable; Set the sequence with select setval('mytable_id_seq',x+1) ;

UnicodeDecodeError using BeautifulSoup

UnicodeDecodeError: 'ascii' codec can't decode byte 0xa3 in position 0: ordinal not in range(128) There’s a rather annoying bug in python 2.5’s sgmllib.py which is the cause. The function convert_charref assumes that ascii characters have values up to 255; the correct limit is 127.

login in testing - must call GET before doing POST

In 0.96, if you dive straight in with a POST to your login page with username/password, you’ll get a login error, saying “Your Web browser doesn’t appear to have cookies enabled. Cookies are required for logging in.”. This is because the test cookie only gets set when you do a GET. So doing this works: response=client.get(login_page) response=client.post(login_page, {'username': username, 'password': password, 'next': home_page}) But just doing the post doesn’t.

test.Client problems logging in (now fixed)

If you’re creating a test user for a unit test, do it this way: newuser=User.objects.create_user('john', '[email protected]', 'johnpassword') rather than this: newuser=User(username="john",email="[email protected]",password="johnpassword") The latter looks correct, but you’ll get problems logging in since Django stores the hash of the password in the db, not the clear text. Another gotcha is that the client.login() function only works with pages where you can’t get at them until you have logged in - if the page is available to AnonymousUser, then login() will always fail.

'module' object has no attribute 'day_abbr'
