Newbie block question

I’m new to Ruby on Rails and I have what I thought was a simple problem,
but I can’t get it to work.

I have a form which should save multiple rows into the mySQL table and I
am trying to use a block to loop through the code to write out to the
database but I can’t get the params to pass in the block.

I used this in my partial:
<%= text_field( :ticketing_price, :price_category, :index => @tdcount
) %>
<%= text_field( :ticketing_price, :number_available, :index =>
@tdcount ) %>

where as the @tdcount increases by one each time the partial is rendered
in the main view, therefore the name of the input is
name=“ticketing_price[0][price_category]” …
name="ticketing_price[1][price_category]’… etc

In my controller, I did this which apparently is wrong:

    params['ticketing_price'].each do |t|
ticketing_price =
ticketing_price = ticketing_price[t]

Please tell me what I am doing wrong. My models are setup correctly (at
least for saving one row at a time, without using the block).
