I have this rhtml, that generate a table with the object @evaluations  
filled it before. The problem is that i need to get those text\_field  
with the data loaded, but instead it’ filled all text\_field whit the  
last @evaluation.  
What i am doing wrong?

\<% form\_for( @evaluations ) do |f| %\>

\<% for evaluation in @evaluations %\>  
\<%= evaluation.id%\>

  
  

```
  <td><%=f.text_field(:id, :size => 2) %></td>
  <td><%=f.text_field(:first_evaluation, :size => 2) %></td>
  <td><%=f.text_field(:second_evaluation, :size => 2) %></td>
  <td><%=f.text_field(:final_evaluation, :size => 2) %></td>

  <td><%= link_to 'Show', evaluation %></td>
  <td><%= link_to 'Edit', edit_evaluation_path(evaluation) %></td>
  <td><%= link_to 'Destroy', evaluation, :confirm => 'Are you

```

sure?’, :method =\> :delete %\>

  
\<% end %\> 

| Student | Commission | Id | Parcial 1 | Parcial 2 | Final |
| --- | --- | --- | --- | --- | --- |
| \<%=h evaluation.student.fistName %\> | \<%=h evaluation.commission.code %\> |

\<%= f.submit "Update" %\>

\<% end %\>

form\_for binds a form builder to one particular object, so trying to  
use it to display text\_fields for multiple objects isn’t going to  
work. If you’re set on using a single form, you might want to look at  
fields\_for (fields\_for gives you a form builder much like what you  
would get from form\_for but just generates the input tags.

Thanks,!  
I founded it text\_field\_tag, i don’t know if is the best way, but in the  
controller i used:  
first\_evaluation = params[:first\_evaluation]  
Then i fill the values with those values.In the view i used:  
\<%= text\_field\_tag(“first\_evaluation[]”, evaluation.first\_evaluation,  
:size  
=\> 2 ). What do you thing about it?

Sallu2…
