Error while upgrading to Rails 2.3.11 (HashWithIndifferentAccess error) - ruby-on-rails

Question

Whenever I attempt to create or update an environment that our app uses, I get the following:
NoMethodError (undefined method `base_url' for #<HashWithIndifferentAccess:0x107162f08>):
app/controllers/environments_controller.rb:64:in `check_base_url_for_https'

As I stated in the title, I recently upgraded to Rails 2.3.11. This error never occurred before. Here is the code in my environments_controller.rb that is being executed when the error occurs:
def check_base_url_for_https
#environment = params[:environment]
if /^https:\/\//i =~ #environment.base_url
#ajax_flash = "<ul class='notice'><li>The website you are trying to test is a secure site. If you are using self-signed SSL certificates please see our <a href='http://support.janova.us'>Support Site</a> and search for SSL for important tips on how to access your site.</li></ul>"
end
end
Does anyone know why this code (specifically the line if /^https:\/\//i =~ #environment.base_url no longer works in Rails 2.3.11?
I would like to add that the code in my app/models/environment.rb appears to be sound too:
def base_url
self[:base_url].try(:gsub, /\$/, '')
end
Does anyone see anything wrong with the code above?

Answer 1

I figured it out: params[:environment] was defined as a hash. Thank you, Frost, for forcing me to see this. Therefore, I changed the line #environment = params[:environment] to #environment = Environment.new(params[:environment]) and it worked.
