__str__ returned non-string (type tuple)

Question

I have a form that keeps throwing me an error in django, Ive tried searching online tried str() on my models but wouldnt work at all. Googled a couple of times tried a coupl

Answer 1

Those commas aren't actually doing what you think they do. The commas make your return value a tuple instead of a string which a __str__ method is supposed to return.

You can instead do:

def __str__(self):
    return '%s %s %s'%(self.soi_l1, self.soi_l2, self.status)

Or use the new-style formatting:

def __str__(self):
    return '{} {} {}'.format(self.soi_l1, self.soi_l2, self.status)
