I need to test if an instance variable in my controller contains a specific value. I think .include? would be the way to do it but that doesn't seem to work.
My code looks something like this:
@names=Model.find_by_sql("select name from ...")
if @names.include?(params[:name])
...
end
The if statement somehow allways evaluates to true.
Thanks
Firstly, find_by_sql is not a good way to do. find_by_sql will return you an object of class Model. Whereas params[:name] is most likely a string. The following should work:
Model.find(:all, :conditions => 'specify conditions here').map(&:name).include?(params[:name])
@names=Model.find(:all, :conditions => '...').map(&:name) if @names.include?(params[:name]) but the .include? allway evaluates to false?
The results of find_by_sql will be (from the docs):
an array with columns requested encapsulated as attributes of the model you call this method from.
You need to search within the results.
