Just adding another possible cause for the “can’t adapt” error. I myself was running a way old psycopg2 (2.0.1) which caused this problem. Upgraded to 2.3.1 and the error went away.

It is exactly what the blog says it is. A tuple is returned and you are trying to access an option not available. Adding ‘created’ (which basically returns true or false) before ‘person’ as done, solves the problem. Then you can access all the stuff from person.
PS – syntax error was classic. Thank you.

Its when you attempt to insert a dict/list/etc value into a varchar or int fields… It won’t str() the value for you so the db won’t be able to ‘adapt’ to the value you attempt to put in.

lol, I’ve had this issue a thousand times over where I’m programming and have an error I’ve seen a thousand times but it still takes me a short while to figure it out… good thinking on blogging about it

Hi I think your error is due to some syntax error. I do not know much about computer programming but I think syntax error cam be. One of my friend has similar kind of error and he checked his syntax

Wir hatten dieses Problem auf einem Server mit mod_python mit zwei verschiedenen Anwendungen. Mit nur einer Anwendung hatte keine Probleme

That’s the only way to go when you work on computers, I do research from time to time and my computer tends to get a lot of viruses when I go to sites not much travelled. To keep track of which web-pages have these viruses you need to write them down to avoid returning to them. In light of all this it’s also a good idea to keep your work saved as well including your research links.

We had this problem on a server running mod_python with two different applications. With just one application there was no problem.

We moved to a wsgi configuration and we haven’t received any “can’t adapt” problems.

For me, this has always meant I’m trying to save/create data which the database will not accept, such as None (NULL) into a non-NULL column.
