i found issues. please try fix them , re-run code.

in update action in uzivatelcontroller

use

@order.update(food_id: food.find(params[:food_id]))

instead of

@order.update(food_id: food.find(params[:food_id]).first)

in edit.html.erb

pass object in url_helper

<%= form_with url: uzivatel_update_path(datum: `your dataum value`, food_id: `your food id`), method: :put, local: true |form| %> <%= form.collection_select(@food_id, food.all, :id, :name)%> <%= form.submit %> <% end %>
