Rails 4+ Edit multiple objects in one form BEST PRACTICE

I have a User, Drinks, Gyms, Foods Model.

class User < ActiveRecord::Base
 has_many :drinks
 has_many :foods
 has_many :gyms
end

I track the number of drinks a user had during the day and save it in the database.I do the same with Foods and Gyms.

I have a User and a Session (for login) controller. So far I haven't needed a controller for my "passiv" Models (Drink, Food, Gym).

Now I have one page with a form on which the User can change the entries of all tables(Drink, Food, Gym) of the previous day.

I think I need to use fields_for in the form to edit objects of multiple Models in one form.

However I don't know how many controllers I need and where I should put in all the business logic... I don't want to do anything quick and dirty, but rather follow certain Best Practices.

My approach so far:

• A lot of forms on one page

  <%= form_for :running, url: data_update_user_path do |f| %>
  <%= form_for :drinks, url: data_update_user_path do |f| %>
  <%= form_for :food, url: data_update_user_path do |f|
  
  

• One DataController who handles all the different updates (It's basically a big if elsif)

  class DataController 
   def update
  
    if params[:drinks]
     #update drinks
    elsif params[:foods]
     #update foods
    elsif params[:gyms]
     #update gyms
    end
   end
  end
  
  

So my question: What is the best practice in such a situation?
