from the API:
*****************************
collection_select(object, method, collection, value_method, text_method,
options = {}, html_options = {})
*****************************
So how would one get the params of this collection_select?
Thanks

no idea what you want .... i#ll just give an example:
<%= collection_select :post, :category, @categories, :id, :name,
{:include_blank => true } %>
will generate
<select name="post[category]">
<option><option>
<option value="1">Diary<option>
<option value="2">Technical<option>
<option value="3">Rants<option>
</select>
- object + method form the name="post[category]"
- the collection has the input for the option tags.
- value_method is the method to use on the collection items to get the
value for value=""
here: @categories.id
- text_method is the method to use on the collection items to get the
display text for the options
here: @categories.name
- the options hash take the options as explained in the API docs of
FormOptionsHelpers, e.g. the :include_blank i used above to create an
empty <option> tag
- the html options hash takes the usua stuff like :class =>
"something"
etc....
when the form is submitted, you can access the selected value with
params[:post][:category]

You should write a book. Nobody explained it like this before.

Can I just say that I have spent the last day or so working this out, and you solved it for me. In my controller, I have been trying to use: @shipping_cost = ShippingCost.find(params[:shipping_cost][:id]) and all I get is an issue of: Couldn''t find ShippingCost with ID So now I switched to the form of: @shipping_cost = params[:shipping_cost][:id] and it works fine. The only problem is I dont know why. Do you know why your method works and my original one does not? Thanks in advance!!!!
