In Flask convert form POST object into a representation suitable for mongodb

Question

I am using Flask and MongoDB. I am trying to convert the content of request.form into something suitable for saving via PyMongo. It seems like something that should come up

You can use werkzeug's getlist to write code like this

data = dict((key, request.form.getlist(key)) for key in request.form.keys())

Now each key of data would be a list which would contain 1 more element. To get results exactly in your format do this

data = dict((key, request.form.getlist(key) if len(request.form.getlist(key)) > 1 else request.form.getlist(key)[0]) for key in request.form.keys())

Now this is inefficient because for each key there are 3 calls to request.form.getlist(key). You can write a loop and get around it.
