UnicodeEncodeError

[Eric]

I am getting this error in the Django Administration section when I
add an entry for a Dashboard object.

When I return to the item in the Admin section, the record has been
added and it displays correctly in the list of Dashboard objects. When
I click on it, it shows correctly. Only when I add a new one or save
one does that happend. And, I noticed that the history is not
populated.

The traceback is:

Exception Type: UnicodeEncodeError at /admin/dashboard/dashboard/1/
Exception Value: ('ascii', u"Eric's Nifty D\xe4shboard Entry", 14, 15,

The model looks like this:

class Dashboard(models.Model):
name = models.CharField("Dashboard name",max_length=100)
fiscal_year = models.IntegerField("Fiscal year")
region = models.CharField("Region", max_length=30)
review_date = models.DateField("Review date")
date_completed = models.DateField("Date Completed")

def __unicode__(self):
return u"%s" % self.name.decode('utf-8')

Can somebody help me figure out what is going on here?

Thanks
Eric

This wouldn't necessarily cause that error, but your __unicode__
method is unnecessarily complicated. All model elements retrieved from
the db are already unicode, so there's no reason to 'decode' from
utf-8. The method should simply return self.name.

In fact, on reflection this could well be the cause of your problem -
because you're calling .decode() on something that is already unicode,
Python will try to encode it to bytes first - and since you haven't
specified an encoding, it will default to ASCII, hence the encoding
error.

Daniel, if I don't do that, I get the unicode error in the list of dashboards in the admin section.

You'd better post the traceback for that, then.

Just to be clear, your method should look like this:

def __unicode__(self):
return self.name
