Reverse lookup in search_fields on Admin

[Emanuel]

Hello all!

I have this models:

class Article(models.Model):
  name = models.CharField(...)

class Sale(models.Model):
  ...

class SaleItems(models.Model):
  article = models.ForeignKey(Article)


And the Admin:
class SaleAdmin(admin.ModelAdmin):
  search_fields = ('...', < and here is the problem >

I want that in the Sale Index Page look all the sales that have sold the article "A"

To accomplished that I tried: 'saleitems__article__name' and it throws the following error:
"

Related Field got invalid lookup: icontains"

Is there a way to do the reverse lookup in search_fields?

Thanks id advance

Hello,

Your code looks right. Do you have other things in search_fields?

Thanks,

Hi.

Yes, I do have another fields. And thanks a lot. I was focus on that particular field that I forgot to see that I had another relation in search_fields wich I was not  using the lookup. It works now.

Thanks
