Multiple objects returned while serializing using cities__name_std

See original GitHub issue

Issue Description

I have serializer like this: `class ExperienceSerializer(serializers.ModelSerializer):

    experience_type = ChoicesField(choices=Experience.EXPERIENCE_TYPE)
    location = serializers.SlugRelatedField(slug_field='name_std', queryset=City.objects.all())

Whenever I enter “Delhi” as location It fails with “get() returned more than one City – it returned 2!” There are cities with same name so how to hanle this scenario?

I just pushed version 0.5 to PyPI, so you should be able to upgrade using pip:

pip install --upgrade django-cities

That version adds slugs to models, and allows you to specify your own slugify() function for all django-cities objects if you don’t want to use the default slugify function I wrote.

Since all of the building blocks are in place, and the default settings should handle this (or at least handle 90% of it), I’m closing this issue. Feel free to reopen it if you run into any issues. Cheers!

You will need to use the slug field for this - that’s what it’s there for after all!

    location = serializers.SlugRelatedField(slug_field='slug', queryset=City.objects.all())

Keep in mind that you will need to fill in that field yourself, but…

I’ve got some changes I need to push, and one of them is creating a unique constraint on the Place (abstract) model’s slug field and giving each model a slugify() method. That should allow you to use the slug field to uniquely identify each city. I’ll try to get that pushed either later today or Friday for you.
