For all the complaints in the Python community that Django contains too much magic, Rails is far more magical; and that magic add complexity that allows these kinds of problems to show up.
That is not to say Django doesn't have issues; it undoubtably does. I just think the hidden surface area is smaller.
Are there complaints in the Python community that Django contains too much magic? Serious question: I don't follow many Python/etc mailing lists so I'm pretty out of the loop on the general impressions people have of Django. I was kind of hoping that Django's magic-removal branch (merged all the way back in 2006!) would have helped here.
