## 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

```
23: <h2>
24: Graduation Year
25: </h2>
26: <%= form.select :year, array_of_years %>
27: <br />
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%\>
