I have a model that has an attribute that is an Array. What's the proper way for me to populate that attribute from a form submission?
I know having a form input with a field whose name includes brackets creates a hash from the input. Should I just be taking that and stepping through it in the controller to massage it into an array?
Example to make it less abstract:
class Article
serialize :links, Array
end
The links variable takes the form of a an array of URLs, i.e. ["http://www.google.com", "http://stackoverflow.com"]
When I use something like the following in my form, it creates a hash: <%= hidden_field_tag "article[links][#{url}]", :track, :value => nil %>
The resultant hash looks like this: "links" => {"http://www.google.com" => "", "http://stackoverflow.com" => ""}
If I don't include the url in the name of the link, additional values clobber each other: <%= hidden_field_tag "article[links]", :track, :value => url %>
The result looks like this: "links" => "http://stackoverflow.com"
