How to solve NameError while importing csv in rails -

i having problem in importing csv files.i got error "nameerror in employee_attendances#index".

model

class employeeattendance < activerecord::base   attr_accessible :date, :emp_id, :in_time, :out_time, :status        def self.import(file)             csv.foreach(file.path, headers: true) |row|             @employee_attendance  = employeeattendance.find_by_emp_id_and_date(row['employee_id'],row['date'].to_date.strftime("%y-%m-%d")) || employeeattendance.new             @employee_attendance.emp_id                = row['emp_id']             @employee_attendance.in_time               = row['in_time']             @employee_attendance.out_time              = row['out_time']             @employee_attendance.status                = row['status']             @employee_attendance.date                  = row['date']             @employee_attendance.save!         end     end  end 

in controller

class employeeattendancescontroller < applicationcontroller   def index  end   def new  end   def create  end   def import    employeeattendance.import(params[:file])    redirect_to employeeattendance_path, notice: "sucessfully created."    end end 

in view (index.html.erb)

<% if flash[:notice].present? %>     <div class="alert alert-success">         <button type="button" class="close" data-dismiss="alert">&times;</button>         <%= flash[:notice] %>     </div> <% end %> <div>     <h2>employee attendance</h2> </div> <%= form_tag import_employee_attendance_index_path, multipart: true %> <%= file_field_tag :file %>   <%= submit_tag "import", :class => 'btn btn-primary' %> <% end %> 

it showing error "undefined local variable or method `import_employee_attendance_index_path' #<#:0xb30a8c88>"

add routes file :

resources :employee_attendances   collection     post 'import'   end end 

or :

resources :employee_attendances   post 'import', on: :collection end 

and view:

<%= form_tag import_employee_attendances_path, multipart: true %> 

thanks
