It’s not hard to submit a form asynchronously in jQuery. Here’s a little example. I put a block like this right below my form element. <script type=”text/javascript”> $(“#my_form”).submit(function() { $.ajax({ type: “POST”, url: “/path/to/post/handler/”, data: $(“#my_form”).serializeArray(), success: function() { // Whatever you want here, like close dialog box, etc. } }); return false; });</script> I [...]
Continue Reading →I had some code where I wanted to break out of a try block in Python. The code looked something like this: try: print “First” if some_condition: # What do I put here to break out of the try block? print “Second” except Exception as e: if e: print “Exception” print “Last” (If some_condition is [...]

Within a matter of seconds, you’ll see traffic from at least all of the following: 50.18.61.103 – - [10/Mar/2011:07:46:15 +0000] “HEAD / HTTP/1.1″ 404 221 “-” “UnwindFetchor/1.0 (+http://www.gnip.com/)” 184.72.240.15 – - [10/Mar/2011:07:46:17 +0000] “HEAD / HTTP/1.1″ 404 183 “-” “MetaURI API/2.0 +metauri.com” 199.59.149.24 – - [...]

So, you’re developing for Python, and you want to use rope and ropemacs and pymacs, but it’s totally busted when you use your virtualenv. In addition, the packaged versions of pymacs+ropemacs for ubuntu 10.10 (and 11.04) are also kind of busted, because they complains with really odd errors. Here’s the solution: Install the latest, greatest [...]

So, you’re developing a Python application. And, you have needs for “production” versus “development” configs. If you’re using a web framework, you might have some support for doing this, but what about your other modules that you’d like to configure in a similar way? What you sort of want to be able to say, anywhere, [...]

Unfortunately, the pre-built binaries for the Python pep8 checker and pyflakes both point directly at #!/usr/bin/python. (FYI I have at least one git pull request out to fix this). This means that if you’re using virtualenv, they’ll complain about a ton of missing packages when you actually just have them in your virtualenv environment. Since [...]

You know, it’s very obvious that some python modules are high quality, and others are utter crap. Please tell me what I’m doing wrong: import logging logging.basicConfig(level=logging.DEBUG) logging.debug(“Hello”) Produces no output on console. Oh? Maybe I need to specify a stream handler? Tried that, with sys.stderr, and still nothing. Maybe I need to set a [...]

There are a ton of different ways you can encode XML, but for the style that looks like this: <xml> <name>Bob</name> … You can use this nice little function to convert it to a native Python object. I’m using this to turn the results of the LinkedIn API from XML to Python, which then gets [...]
Continue Reading →Here I am, writing this post instead of coding. Why? Because I’m having to read through the Pyramid source code trying to figure out what the heck is going on with configuration. Or, to be more specific, how can I load module X when I’m in production, but module Y when I’m in development. I [...]

So, you need short URLs for your pages, and pages are objects in your MongoDB database. How do you generate these short ids? The pattern I’m using is quite simple, but requires that you create a unique index on a field called “short_id.” Since I’m using minimongo, it’s easy to declare these Indexes programatically, [...]
