 I have my query into validation to find if exist a duplicate name in my
 model


 {{{
     def validate_name(self, value):
         if not value:
             raise serializers.ValidationError('Proporciona un valor, por
 favor.')

         try:
             exist_name = FundingSource.objects.filter(name__iexact=value)
 # here is the error __icontains is NOT WORKING
             if len(exist_name) > 0:
                 raise serializers.ValidationError('Este nombre ya fue
 usado, por favor proporciona otro valor.')  # I need display this message
 in my console to be sure that exists a duplicate
         except Exception as e:
             pass
         else:
             return value
 }}}

 I have in my model

 Funding 1
 Funding 2
 Funding 3
 Funding 4

 Next, I tried to type `funding 1` to disallow me to create that name, but,
 the queryset display me

 <QuerySet []>

 Then, create new one item in my table.

 Funding 1
 Funding 2
 Funding 3
 Funding 4
 funding 1

 So this is wrong, your __iexact is bad,

 so I need that Django developer team resolve this, now.

 It's urgent, please. What is the best way to develop __iexact or
 __icontains.

 Thanks
