I have a model order and user.
user - has_many: order
order - belongs_to: user
I want to make a check on the order form.
<% if current_user%>
form where the name of the order form will be recorded from the user
<% else%>
regular order creation form
<% end%>
the task is how to write data of another model to the model?
You can do this in the controller
for eg.
Class OrdersController < ApplicationController
def new
if current_user
# this will set the user_id field
# you can set additional attributes here
@order = current_user.orders.build({attribute: value})
else
@order = Order.new
end
end
...
in view
= form_for @order do |f|
...
You can Try accepts_nested_attributes_for
