use request when using rest_framework.serializer

Question

I use Django REST Framework and I have a django model class like this:

class Venue(models.Model):
    user=models.ForeignKey(User)

I would then want to serialize this:

from rest_framework import serializers
import models

class VenueSerializer(serializers.ModelSerializer):

    class Meta:

        model=models.Venue
        fields=('id','user','is_current_user')

where is_current_user is a boolean value, somehow like this

def is_current_user(self):
    return self.request.user==self.user

How can I do this? Do I have request somewhere in serializer? Or should I do this somewhere in the model?

Less convenient options are:

to send the current user id to the client in another way and compare there, but then I'd have to expose the user of each model to the client.
to iterate over the json after serialization
manually without the serializers create a json from a queryset

I would suggest using SerializerMethodField:

class VenueSerializer(serializers.ModelSerializer):
    class Meta:
        model=models.Venue
        fields=('id','user','is_current_user')

    def get_is_current_user(self, obj):
        return self.context['request'].user == obj.user
