Using select_year in form_for helper block

Rails
1

I’m having trouble trying to implement a selection field of years in a
form_for block for Views. Initially, I wrote something like this:

Sign-up

<% array_of_years = generate_year_array() %> <% form_for :person do |form| %>

First Name

<%= form.text_field :first_name, :size => 30 %>

Last Name

<%= form.text_field :last_name, :size => 30 %>

RIN

<%= form.text_field :last_name, :size => 10 %>

Email

<%= form.text_field :last_name, :size => 30, :value => '@rpi.edu' %>

Graduation Year

<%= form.select :year, array_of_years %>
<%= submit_tag "Join In!" %> <%end%>
--------

With the helper, generate_year_array() as:

Methods added to this helper will be available to all templates in

the application.
module ApplicationHelper

#generate an array years from 4 years past to 8 years in future
def generate_year_array( year = nil )
if year
default_year = year.to_i
else
default_year = Time.now.year + 4
end
begin_year = default_year - 8
end_year = default_year + 4
output = []
begin_year.upto( end_year ) do |this_year|
output.push this_year.to_s
end
end

end

This, unfortunately, gave me the following error:

  1. Error:
    test_valid_valid_sign_up(SignUpControllerTest):
    ActionView::TemplateError: undefined method `inject’ for 2004:Fixnum
    On line #26 of sign_up/sign_up.rhtml

28:     <%= submit_tag "Join In!" %>
29:   <%end%>

Lo and behold, a little search helped me find a better solution:
select_year and fields_for. However, I’m clearly doing something
wrong in the example I’ll bring up next, yet the example is a little
too vague to figure out what I mistake I’ve made. Can anyone help me
out on this?
The code I’ve attempted to use:

Edit

<% form_for :person do |form| %>

First Name

<%= form.text_field :first_name, :size => 30 %>

Last Name

<%= form.text_field :last_name, :size => 30 %>

RIN

<%= form.text_field :last_name, :size => 10 %>

Email

<%= form.text_field :last_name, :size => 30 %>

Graduation Year


<% fields_for @person.year do |year_field| %> <%= year_field.select_year( Time.now.year + 4, :start_year => Time.now.year - 4, :end_year => Time.now.year + 8 ) %> <% end %> <%= submit_tag "Join In!" %> <%end%>
