[Python/Django] How do I change the directory of InMemoryUploadedFile?
It seems that if I do not create a ModelForm from a model, and create a new object and save it, it will not respect the field's upload directory.

I have text files with a lot of uniform rows that I'd like to load into a mysql database, but the files are not completely uniform.

Why is wxGridSizer much slower to initialize on a wxDialog then on a wxFrame?
It seems that this is specific to windows, here is an example that reproduces the effect: import wx def makegrid(window): grid = wx.GridSizer(24, 10, 1, 1) window.SetSizer(grid) for i in xrange(240): cell = wx.Panel(window) cell.SetBackgroundColour(wx.Color(i, i, i)) grid.Add(cell, flag=wx.EXPAND) ...
