I want to store object values but how to store multiple record at same
time using controller.

my controller code -

def create
  params[:f].each do |user_params|
       Detail.new(user_params).save
  end
end

my view code -

<%= form_for(:detail, :url => {:controller => 'details', :action =>
'create'}) do %>
  <% @info.each do |article| %>
    <%= hidden_field_tag "f[][columns_id]", article.id %>
    <p>
      <td><%= article.value %></td>
      <td><%= text_field_tag "f[][column_value]" %></td>
    </p></br>
    <%= hidden_field_tag "f[][users_id]", current_user.id %>
  <% end %>
  <p class="button"><%= submit_tag %></p>
<% end %>

You cannot use params[:f] that way.

#3

You want to store what object values? Is it just one object or two related objects?Try using this rails convention http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html

Make your life easier, stick to rails conventions.

I suggest you use a Form Object for this: http://blog.codeclimate.com/blog/2012/10/17/7-ways-to-decompose-fat-activerecord-models/#form-objects
It’s not that our form is overly complex, but it falls outside of rails conventions.

Anyway, please, do not put such logic in the controller, make a static method on the model at least.
