Rails - Mar 2007 - Multiple objects of the same type with one form - REST

I''ve looked at all the tutorials on how to create multiple objects of
the same type with one form. However, I cannot get it to work with my
REST app. This is what I have tried:
----- Controller ---------

''new'' action ----------
def new
  @students = []
  5.times { @students << Student.new }
end

''create'' action ----------
params[:students].values do |student|
      Student.new(student) unless student.values.all?(&:blank?)
end

-------- View -----------
<% @students.each_with_index do |student, index| %>
     <% fields_for "students[#{index}]", student do |s| %>
           <%= render :partial =>
''students/student_form'', :locals =>
{:f => s} %>
     <% end %>
<% end %>

I cannot figure out why this is not working. All the student objects
are correctly in the parameters but they will not get saved. Please
help.

You aren''t saving the Student? Either by calling Student.save after or
using .create instead of .new. I believe.

Here is my full create method:

def create
    params[:students].values do |student|
      Student.new(student) unless student.values.all?(&:blank?)
    end

    respond_to do |format|
      if @????.save
        flash[:notice] = ''Students were successfully created.''
        format.html { redirect_to students_path }
      else
        format.html { render :action => "new" }
      end
    end
  end

As you can see, since I do not have an instance variable, I don''t know
what to put in the if clause. But even if I replace new with create,
it still doesn''t create the objects. I''ve tried getting rid of
the
respond_to just to see if the object would be created but no luck.

Is something like possible with REST?

Finally, I got the objects to save! Here is my new create method:

def create
  params[:students].each_value do |student|
     @student = Student.new(student) unless student.values.all?
(&:blank?)
     @student.save
  end
  flash[:notice] = ''Family was successfully created.''
  redirect_to student_url(@student)
end

Now, as you can see, I had to get rid of my respond_to block. How can
I handle errors using the if clause since the values of @student
change with each object?

Everything works perfectly now after I followed this tutorial:
http://www.railsforum.com/viewtopic.php?id=1063

Here is a tip for fellow newbies: Get your model relationships
correct. Read the ActiveRecord chapters in AWDwR thoroughly.
