Question

我的迁移文件：

    def self.up
create_table :geo_data do |t|
  t.column :zip_code,  :string
  t.column :latitude,  :float
  t.column :longitude, :float
  t.column :city,      :string
  t.column :state,     :string
  t.column :county,    :string
  t.column :type,      :string
end
add_index "geo_data", ["zip_code"], :name => "zip_code_optimization"

csv_file = "#{RAILS_ROOT}/db/migrate/geo_data.csv"
fields = '(zip_code, latitude, longitude, city, state, county)'

execute "LOAD DATA INFILE '#{csv_file}' INTO TABLE geo_data FIELDS " +
        "TERMINATED BY ',' OPTIONALLY ENCLOSED BY \"\"\"\" " +
        "LINES TERMINATED BY '\n' " + fields
end

当我尝试使用文件填充数据库时出现此错误：

   Mysql2::Error: Can't get stat of '/home/sean/project/db/migrate/geo_data.csv' (Errcode: 13): LOAD DATA INFILE '/home/sean/project/db/migrate/geo_data.csv' INTO TABLE geo_data FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY """" LINES TERMINATED BY '
   ' (zip_code, latitude, longitude, city, state, county)
