dumb question alert: use *both* ruby on rails and python possible?
If you're parsing data with python, presumably it's going be put into a database. As long as this is the case you can just run two apps standalone. Saying that, using one language and framework is a better solution, especially when you think that you won't be able reuse any code between the two applications if they are written in two different languages.
Also I know Ruby has good libraries to do all of what is mentioned in your post, as I'm sure Python also does, so there seems little advantage in using the two together.
the front end and end-user data-collection we want to build in RoR since it's just some simple forms connected to a database.
The integration with other external api's such as twitter and facebook and parsing of the data entered by the users we want to do in python, mostly because the developer for that part knows python.
Is that possible?
