Using Unicode in django

[temiloluwa adesina]

Hello 

I just joined this group and i have problems with representing multiple fields in admin using __unicode__, when i try to call this data it returns just one of them:

class Crop(models.Model):
    name = models.CharField(max_length=30)
    importance = models.TextField()
    cultivation = models.TextField()
    def __unicode__(self):
        return u'%s %s %s' % (self.name, self.importance, self.cultivation)

but rather than returning just the data in the importance field, it returns all the data in each separate field together.

Pls i would appreciate anyone's assistance.

Not sure I understood the problem. Are you trying to print only the data in the "importance" field?

If so, try:

class Crop(models.Model):
    name = models.CharField(max_length=30)
    importance = models.TextField()
    cultivation = models.TextField()
    def __unicode__(self):
        return u'%s' % (self.importance,)

Thanks for your reply i found another way to do it, i could just make it work like this:

b= Crop.objects.all()
nm= b.name
imp= b.importance
cuv= b.cultivation

realized this would help me retrieve the individual data that i wanted to get.

That __unicode__() return value is a concatenation of the three named
fields and I assume that is what you want. When the object is returned
its name is mentioned first (Yam) followed by a space followed by
whatever data is in the importance field followed by a space then
cultivation

Your screenshot seems to be showing that.

If all you want is the importance info, just make __unicode__() return
that and nothing else.

Whatever is returned by __unicode__ is the object's identification.

You seem to have a good handle on that so I suspect I haven't understood
your question.
