How to get URL param values into an array?

Question

I am developing an Rails 3.2 app. I need to get the values from the URL params and add them to an array so that I can use .to_sentence to print them out (for search).

These are my params (there are more on some search pages).

search=true&title=s&client=&tags=&status=&start_date=&end_date=

I tried this but that does not get only the values but both key and value.:

params.map(&:to_s)

Update

I figured out how to get the values now but I need not to map values that are nil.

<%= params.each_value.map{|value| value }.to_sentence %>

Try this:

values = params.values.reject(&:blank?) # ["true", "s"]

values returns all the values from the Hash, including the empty strings

.reject(&:blank?) is a shorthand for .reject { |v| v.blank? }. reject returns a new Hash, skipping all the values which blank? method returns true, so this eliminates all the blank values. Note that blank? also returns true for empty strings.

See the docs for these methods:
