Pass variable to Simple_Form custom input - ruby-on-rails-3

Question

I'm trying to record multiple records using a simple_form custom input. My input is:
class InlinedateInput < SimpleForm::Inputs::Base
def input
"#{#builder.text_field("startmonth", input_html_options)}".html_safe + "/" + "#
{#builder.text_field("startday", input_html_options)}".html_safe + "/" "#
{#builder.text_field("startyear", input_html_options)}".html_safe + "To: " "#
{#builder.text_field("endmonth", input_html_options)}".html_safe + "/" + "#
{#builder.text_field("endday", input_html_options)}".html_safe + "/" "#
{#builder.text_field("endyear", input_html_options)}".html_safe + "Price:" "#
{#builder.text_field("price", input_html_options)}".html_safe
end
#Makes the label target the day input
def label_target
"month"
end
end
Basically, the problem is that I have a bunch of different inputs defined in this input. So if I try to use this method a few times in a form it will only submit the last one. I need someway to pass a counter variable from my form so that I can have startday_1, startday_2, etc. Any ideas?

You can pass any parameter you want to your custom input through options hash.
For example, you can easily pass custom parameter (counter) to your input:
= f.input :my_field, :as => :custom_input, :counter => 2
and access it into your custom input code:
class CustomInput < SimpleForm::Inputs::StringInput
def input
counter = options[:counter] || -1
input_html_options[:value] = counter
super
end
end
