Any tutorials on how to do multiple row (data grid like) form?

Hello,

I am trying to create a multiple row / data grid like input form and am not
sure how to proceed. I am wondering if there are any good tutorials on how
to do something like this.

To be more exact in what I am trying to do, imagine it is an expense report
application in which a user has to enter the expense amount, a description,
and select the category under which the expense belongs. The form consists
of 5 rows, each row consisting of a field to enter each piece of information
for a single expense. The form would also offer the user the chance to add
or subject rows.

I am looking for a tutorial that covers both the view and controller side of
doing this as I am fairly new to Rails.

Thank you for you help with this.

Chris Johnston

Re: Any tutorials on how to do multiple row (data grid like) form?

I think you may be looking for something like this:

<% form_for :expenses do |form| %>
  <% @expenses.each_with_index do |expense, index| %>
    <%= form.text_field(:amount,      :index => index) %>
    <%= form.text_field(:description, :index => index) %>
  <% end %>
  <% submit_tag %>
<% end %>

then in the controller you should be able to access the data as a hash
of hashes:

params[:expenses].keys.each do |index|
  Expense.create(params[:expenses][index])
end

or however you want to handle that.

None of that is tested but I >think< that is the general idea.

Hope that helps!

Cool, from reading through it, it looks like might just do it. Thanks.

Re: Any tutorials on how to do multiple row (data grid like) form?

Hi,

It isn''t working for me. Are there any good tutorials on putting
together
complex forms?

What I have is this:

Object A, in my example it is ExpenseReport. ExpenseReport contains several
fields of its own like submitted_date, current_project, comments.

It also has a collection of LineItems which contains the amount,
establishment, comments.

A LineItem contains an ExpenseType which is another model object. In the
form, this would be represented by a drop down box. So the whole form looks
something like this:

<% form_for :report, :url => { :action => ''create''}
do |form| %>

      <label for="report_project">Name</label>
      <%= text_field ''report'', :project, :size => 40 
%>

      <label for="report_submit_date">Report Submitted
on</label>
      <%= datetime_select ''report'',
''submit_date''  %>

        Report Line Item</legend>

          <% fields_for :line_items do |line_item_form| %>
            <% @line_items.each_with_index do |line_item, index| %>

              <% fields_for :expense_categories do |expense_category| %>
                <%= expense_category.collection_select(:id,
@expense_category, :id, :name) %>
              <% end %>

              <%= text_field :line_item_form, :amount, :index => index
%>
            <% end %>
          <% end %>

      <label for="report_comments">Comments</label>
      <%= text_area ''report'', ''comments'',
:rows => 5, :cols => 60 %>
      <%= submit_tag "Create" %>

    <% end %>

The problem that I am having right now is twofold; first, when I use the
code listed below to extract the line_items and create those objects I am
getting a ''nil object'' error and second, in the params, there
is only one
listing for the expense_category instead of 5.

Anyone have ideas or tutorials they can point me to for this kind of thing?

Thanks,
Chris
