I don't see that reflected in the stats for London on Indeed.co.uk. If you search by title there are currently 25% more Django jobs than Rails whilst Python:Ruby is 4.2:1. Node:Rails is about 3:1. I've also noticed a steady decline in Rails job postings. You're seeing about half the number of Rails postings compared with a year ago. Another interesting trend is that Python has more adoption outside London than Ruby in relative terms. Ruby is very much a niche London phenomenon unlike the USA where Ruby/Rails jobs are spread more evenly across the country.
