如何使用加载数据本地infile从迁移中将csv文件加载到rails中？

Question

I have my csv file in my public folder, and i'm trying to load it from a migration, but I get a file not found error using this script :

ActiveRecord::Base.connection.execute(
  "load data local infile '#{RAILS_ROOT}/public/muds_variables.csv' into table muds_variables " +
  "fields terminated by ',' " +
  "lines terminated by '\n' " +
  "(variable_name, definition)")

I've checked and re-checked the file path, and that's definitely where it lives, I've also tried it just using the file name without any of the path, and a few other combos, but I can't make it work :(. can anyone help me out with this?

here's the error : Mysql::Error: File '/home/chris/rails_projects/muds/public/muds_variables.csv' not found (Errcode: 2): load data local infile '/home/chris/rails_projects/muds/public/muds_variables.csv' into table muds_variables fields terminated by ',' lines terminated by ' ' (variable_name, definition)

答案是，如果您实际上有一个名为muds_variables.csv的文件，则此方法应该起作用。
