Ruby on rails Unknow attribute when importing csv file to database -


i'm trying import csv file ruby on rails app database. got error unknown attribute '2191' landslide. when running bundle exec rake db:import_csv. 2191 first item on first row of csv file.

import_csv.rake

require 'csv' namespace :db   task :import_csv => :environment     csv.foreach("sample_landslides.csv", :headers => true) |row|       landslide.create!(row.to_hash)     end   end end

schema

  create_table "landslides", force: :cascade |t|     t.integer  "total_id"     t.integer  "year_id"     t.date     "start_date"     t.date     "end_date"     t.integer  "day_number"     t.string   "continent"     t.string   "country"     t.string   "location"     t.string   "type"     t.integer  "admin_level"     t.float    "lat"     t.float    "lng"     t.boolean  "mapped"     t.float    "spatial_area"     t.integer  "fatalities"     t.integer  "injuries"     t.string   "notes"     t.datetime "created_at",   null: false     t.datetime "updated_at",   null: false     t.string   "trigger"   end

as per knowledge if using row_to hash csv headers must match model attributes.

require "csv"  header_map = {   "total" => :total_id, }  header_converter = ->(header) {   header_map.fetch(header, header).to_sym }  csv = <<end  column1,column2,ext:mat:pidtc  100,200,300  400,500,600 end  csv.new(csv, headers: true, header_converters: header_converter).each   |row|   p row.to_hash end
