Is there a way to determine which fields in the model are editable in the admin application?

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 with a header, but I don't want the user to be able to edit it with the administrator. I assumed that adding the = [] fields to the admin object and not including slug would work, but it is not. I also tried setting editable = False in the model, but that also did not work (infact, stops the page from rendering).

Thoughts?

:

def save(self):
    from django.template.defaultfilters import slugify

    if not self.slug:
        self.slug = slugify(self.title)

    super(Your_Model_Name,self).save()

This snippet gives you an AutoSlugField with the same behavior you are looking for, and adding it to your model is single-line.

Answer 5

In addition to the redefinition saveof the value of the generated, you can also use the option to exclude in ModelAdminorder to prevent the display of the field in the admin:

class EntryAdmin(admin.ModelAdmin):
    exclude = ('slug',)
