how to call a active record named scope with a string

Question

I\'m sure I\'m miss understanding the use of call but I thought I could do something like this.

@case_studies = CaseStudy.call(\"some_named_scope\")
         


        

Answer 1

Although @kolrie has the correct answer, it is not safe at all.

It should be whitelisted as follows:

scope = ["first_scope", "second_scope", "default_scope"].include? params[:action] ? params[:scope] : "default_scope"
@case_studies = CaseStudy.send(scope)
