I finally stumbled upon this link “A CORS POST request works from plain javascript, but why not with jQuery?” that notes that jQuery 1.5.1 adds the Access-Control-Request-Headers: x-requested-with header to all CORS requests. jQuery 1.5.2 does not do this. Also, according to the same question, setting a server response header of Access-Control-Allow-Headers: * does not … Read more
They’re not exactly comparable. CherryPy provides url routing and a request/response abstraction, which makes prototyping very easy (although I find vanilla mod_python just as convenient). Django is a complete web application “stack”, including a templating system and an object-relational mapper.
This part of documentation can help you: The special constants true, false and none are indeed lowercase. Because that caused confusion in the past, when writing True expands to an undefined variable that is considered false, all three of them can be written in title case too (True, False, and None). However for consistency (all … Read more
Check out from the tutorial a section entitled “Auto Reloading” During development, you have to restart the server a lot to test your recent changes. The auto reloader can do this for you. Every time you edit a module file, the reloader restarts the server process and loads the newest version of your code. This … Read more
Regarding the KeyError: The strings that are printed in the repr of the __table__.columns object are NOT the keys, and because you have multiple id columns there is some name munging going on. You probably want to do “persons_id” rather than “persons.id” but I recommend printing __table__.columns.keys() to be sure. Regarding the AttributeError: SQLAlchemy maps … Read more
We have a pretty comprehensive caching solution, as an example in conjunction with embedded hooks, in 0.6. It’s a recipe to subclass Query, make it aware of Beaker, and allow control of query caching for explicit queries as well as lazy loaders via query options. I’m running it in production now. The example itself is … Read more
There is a snippet on Flask’s website about a ‘catch-all’ route for flask. You can find it here. Basically the decorator works by chaining two URL filters. The example on the page is: @app.route(“https://stackoverflow.com/”, defaults={‘path’: ”}) @app.route(‘/<path:path>’) def catch_all(path): return ‘You want path: %s’ % path Which would give you: % curl 127.0.0.1:5000 # Matches … Read more

Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call: >>> import requests >>> r = requests.post(‘http://httpbin.org/post’, json={“key”: “value”}) >>> r.status_code 200 >>> r.json() {‘args’: {}, ‘data’: ‘{“key”: “value”}’, ‘files’: {}, ‘form’: {}, ‘headers’: {‘Accept’: ‘*/*’, ‘Accept-Encoding’: ‘gzip, deflate’, ‘Connection’: … Read more
