Question

I got a task to access param values for creating new user.My controller code for create is

def newstudent
    @student = Student.new(params)
   puts "+++++++++++"
   puts params.inspect

    if @student.save 
    respond_to do |format|
      format.html # new.html.erb
      format.json { render :json => @jtable }
    end
    end
  end

But by doing this i had got some error in terminal.It shows like this

ActiveModel::MassAssignmentSecurity::Error (Can't mass-assign protected attributes: action, controller):
  app/controllers/students_controller.rb:42:in `new'
  app/controllers/students_controller.rb:42:in `newstudent'

Please help me to solve the problem?

Answer 1

This is my controller for add new student. By getting that error message you must reject controller and action using @student = Student.new(params.reject {|key,value| key =="controller" || key =="action"}) code.

 def newstudent
        @student = Student.new(params.reject {|key,value| key =="controller" || key =="action"})

        if @student.save 
          @jtable = {'Result' => 'OK','Record' => @student.attributes}
        else
         @jtable = {'Result' => 'ERROR','Message'=>'Empty'}
        end  
        respond_to do |format|
          format.html # new.html.erb
          format.json { render :json => @jtable }
        end

      end
