Model with OnetoOneFeild inline in admin cannot be created

[tejinderss]

I have models Foo and Bar for example:

    class Foo(models.Model):
        ....

    class Bar(models.Model):
        foo = models.OneToOneField(Foo)
        required_field = models.CharField(blank=False)

and in the admin.py i have:

    class BarInline(admin.StackedInline):
        model = Bar

    @admin.register(Foo)
    class FooAdmin(admin.ModelAdmin):
        inlines = [BarInline]

Now the issue is on the save form in admin, if i try to create foo instance without providing any bar data in barinline form, i get error that bar's required field is required and if i make all fields optional, it creates the bar instance anyway without any data. I have played with min_num and max_num but in vain.
