Question

I have got a many to many relationship between these to models :-

user.rb and city.rb, so that I can access user.cities and city.users.

Once the user clicks add city I want to add those cities in the temp variable like this

temp = []
city = City.find(params[:id])
temp << city

then I want to iterate over the temp doing something like this temp.each do |t|...
then once the user clicks confirm my cities I want to add these cities in user.cities

What might be the best approach to get the desired result?

Answer 1

i think the best approach is to use javascript. Simply on click save cities ids in js, and on submit send them to appropriate action which will save them.
