Hi Guys,
I''m having a little bit of trouble editing multiple model objects in a
single form. I''ve got a model Person with two attributes: name and
gender. For simplicity, gender can be a text input.
I''d like to be able to display all Person objects (name and gender) in
a form. So, each model object gets its own row.
In my controller, I fetch the objects with:
@people = Person.find(:all)
In my view, I loop through @people and render a form:
<% for person in @people %>
<div>
<span><%= person.name %>:</span>
<span><%= text_field :person, :gender %></span>
</div>
<% end %>
I''ve built plenty of forms that handle attributes from a single model
object. How would I edit multiple objects within a single form? In
specific, I''m not sure how to set the name attribute in the gender
field. And, i''m not sure how to deal with the params hash in my
controller to update the models.
Thanks in advance,
Raj

Hi Todd,
I was able to get the form to render properly. I''m still unclear
about how to set the values of the field_for fields and access them in
the controller code. When I use the following code, only one form
value is getting submitted.
<% form_tag do %>
<% @people.each do |person| %>
<% fields_for(person) do |f| %>
<div>
<%= person.name %>:
<%= f.text_field :age %>
</div>
<% end %>
<% end %>
<%= submit_tag %>
<% end %>
Thanks,
Raj
