Hello Nikolas,

It should be a matter of using annotate() with Func(F('field'), function='REPLACE')) expressions but I don't think we should be documenting every single use of Func.

I suggest you take a look at how you can get support if the documentation isn't enough to help you solve your issue.

i try

obs = Goods.objects\
                    Value("'-'"), Value("' '"),

            Q(data__contains="Andrew") |
                    Value("'-'"), Value("' '"),

but cant compare to function (not field), this is not documented, can litle help please?
and i think must be more examples in Docs, complex and big examples, very need.

Thanks for great soft!
