Not able to create funding table for multiple children - ruby-on-rails

Question

each child can apply for funding. But when I apply for funding it always created funding application for Child_id:1 even if I am applying for some other child. funding belongs to child and children can have many fundings. please help
fundings_controller.rb
def create
#funding = Funding.new(funding_params)
#funding.child = Child.find(child_user.ids[0])
if #funding.save
flash[:success] = "Thankyou for submitting"
redirect_to funding_path(#funding)
else
render 'new'
end
end
application_controller.rb
def current_user
#current_user ||= Family.find(session[:family_id]) if session[:family_id]
end
def parent_user
#parent_user ||= Parent.find(session[:family_id]) if session[:family_id]
end
def child_user
puts session[:family_id]
#child_user ||= Child.where(:parent_id=>session[:family_id]).limit(1) if session[:family_id]
end

Answer 1

Since a parent can only apply for funding for one child at a time, let them choose which child in the funding form, and pass in the :child_id as part of the funding parameters to the FundingsController#create action.
fundings_controller.rb:
def create
#funding = Funding.new(funding_params)
if #funding.save
flash[:success] = "Thankyou for submitting"
redirect_to funding_path(#funding)
else
render 'new'
end
end
application_controller.rb
def current_user
#current_user ||= Family.find(session[:family_id]) if session[:family_id]
end
def parent_user
#parent_user ||= Parent.find(session[:family_id]) if session[:family_id]
end
def current_children
puts session[:family_id]
#current_children ||= Child.where(:parent_id => parent_user.id) if session[:family_id]
end
helper_method :current_children

Answer 2

Looking at your models, this should be part of the database tables.
|Family |Parent |Child |Funding |Organisation |
|-------+----------+-----------+----------+--------------|
|id | id | id |id |id |
|-------+----------+-----------+----------+--------------|
| |family_id |parent_id |child_id |founding_id |
The problem I see is that when you create a new funding you can add just one child. But you got a collection then you limited to 1 to make it work.
But you are adding only the first child fetched for the current_user (.limit(1)).
What you should do is for each one of the children, belonging to the parents, belonging to the current_user (found in Family), you need to create a new funding.
But the code changes a lot. Removing .limit(1) to get all the children collection, scan the collection and create a funding for each children.
But I think you need to create a new action in a different controller for that.
Or, but I do not know your purpose, consider to use a different association, like has_and_belongs_to_many between Child and Funding.
