Name/Value pairs

[ricklach]

I have a table with id, name, value that is used to configure my application. I want to produce a form that has a number of fields that a new user would fill in to set-up the program - this is the source of the name/value pairs. Is there a way with ror to take all of the name value pairs from a form and add them to the database in an iterative fashion. For example: name/bob save, phone/123-456-1234 save, etc.

You could use a hidden tag to store the count of the fields present and iterate over each if the user is entering the name/value pairs himself. If the name value is already in there and the user is merely filling in multiple "values" for "names" which already exists, you could do:

<%= NameValue.find(:all).each do |pair| -%>
<%= pair.name %>: <%= text_field_tag 'value_' pair.id.to_s, pair.value %><br />
<% end -%>

Then iterate over each and check to see if its filled in on the controller side.
Umm... its late... do you see what I'm saying?

You can use Hash class.

Can you provide an example of using hash class to perform the task?

Ditto. I'd like to see how you would use the hash class for these DB values...
It seems more efficient to use ActiveRecord since they are columns.
