[Fixed]-Django 1.5 admin inline extra

I ran into the same issue because I had the static admin content in a directory that was outside of django’s install. Copying the Django 1.5 static content from django/contrib/admin/static/admin/js/ to STATIC_ROOT/admin/js fixed the issue.

the better solution would be to override the get_extra method of the inline itself. This works in Django 1.9, though i cannot say for earlier versions

All you have to do is add extra field.

For Example:

1. models.py:

class Category(models.Model):
    name = models.CharField(max_length=50)
    def __str__(self):
        return self.name


class Product(models.Model):
    name = models.CharField(max_length=50)
    price = models.IntegerField()
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

    def __str__(self):
        return '{}, {}'.format(self.name, self.company)

2. admin.py:

    class InlinesProduct(admin.StackedInline):
        model = Product
        extra = 0     #<=== For remove empty fields from admin view

    @admin.register(Category)
    class CategoryAdmin(admin.ModelAdmin):
        inlines = [InlinesProduct]

Use "get_extra()" as shown below if "extra" field doesn’t work:

class ModelInline(admin.StackedInline):
    model = MyModel
    # extra = 0

    def get_extra(self, request, obj=None, **kwargs):
        return 0 # Is equivalent to "extra = 0"
    
class OtherModelAdmin(admin.ModelAdmin)
    inlines = [ModelInline]
    
admin.site.register(OtherModel, OtherModelAdmin)
