Question

Assume the following:

models.py

class Entry(models.Model):     title = models.CharField(max_length=50)     slug = models.CharField(max_length=50, unique=True)     body = models.CharField(max_length=200) 

admin.py

class EntryAdmin(admin.ModelAdmin):     prepopulated_fields = {'slug':('title',)} 

I want the slug to be pre-populated by the title, but I dont want the user to be able to edit it from the admin. I assumed that adding the fields=[] to the admin object and not including the slug would have worked, but it didnt. I also tried setting editable=False in the model, but that also didnt work (infact, stops the page from rendering).

Thoughts?

For this particular case you can override your save method to slugify (it’s built-in method, look at django source) the title and store it in slug field. Also from there you can easily check if this slug is indeed unique and change it somehow if it’s not.

Consider this example:

def save(self):     from django.template.defaultfilters import slugify      if not self.slug:         self.slug = slugify(self.title)      super(Your_Model_Name,self).save()
