Changing case (upper/lower) on adding data through Django admin site

Question

I'm configuring the admin site of my new project, and I have a little doubt on how should I do for, on hitting 'Save' when adding data through the admin site, everything is converted to upper case...

Edit: Ok I know the .upper property, and I I did a view, I would know how to do it, but I'm wondering if there is any property available for the field configuration on the admin site :P

Answer 1

you have to override save(). An example from the documentation:

class Blog(models.Model):
    name = models.CharField(max_length=100)
    tagline = models.TextField()

    def save(self, force_insert=False, force_update=False):
        do_something()
        super(Blog, self).save(force_insert, force_update) # Call the "real" save() method.
        do_something_else()

Answer 2

If your goal is to only have things converted to upper case when saving in the admin section, you'll want to create a form with custom validation to make the case change:

class MyArticleAdminForm(forms.ModelForm):
    class Meta:
        model = Article
    def clean_name(self):
        return self.cleaned_data["name"].upper()

If your goal is to always have the value in uppercase, then you should override save in the model field:

class Blog(models.Model):
    name = models.CharField(max_length=100)
    def save(self, force_insert=False, force_update=False):
        self.name = self.name.upper()
        super(Blog, self).save(force_insert, force_update)
