Error while upgrading to Rails 2.3.11 (HashWithIndifferentAccess error)

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>):

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.
