Koľajnice: ako predkladať viacero foriem rovnaké tabuľky - ruby on rails, ruby, formulároch, ruby on rails 3

Momentálne budujem nástroj na prácu.Zahŕňa to odovzdanie viacerých časov začiatku a konca úlohy každý deň. Existuje niekoľko pracovných miest a každá z nich má každý deň nový čas spustenia. Pre urýchlenie procesu chcem odoslať všetky prevádzkové časy v jednej forme. Momentálne sa zobrazujú všetky tieto formuláre, ale keď zadám, prejde iba jeden. Čo mi chýba?

odpovede:

Ignorujte komentáre o Ajaxe, fields_for urobí, čo chceš, a ajax je pre toto komplexná divoká husacia honička. Musíte len presunúť značku formulára na vonkajšiu stranu slučky.

    <% @runtimes.each do |runtime| %>
<%= fields_for @runtime do |r| %>
<%= render "form" %>
<% end %>
<% end %>

by sa malo zmeniť na

    <% @runtimes.each do |runtime| %>
<%= form_tag %>
<%= fields_for @runtime do |r| %>
<%= render "form" %>
<% end %>
<% end %>
<% end %>

A odstráňte form_for vnútri _form.html.erb. Potom budete musieť vytvoriť novú akciu radiča, ktorá dokáže spracovať viac parametrov @runtime naraz, napríklad #update_batch.

To nie sú všetky detaily, ale to je myšlienka. To, čo sa chcete stať, je jeden formulár, ktorý má parametre všetko naraz.
