Hi, folks –
Sorry if this has been discussed ad infinitum but I’ve been searching and testing for hours and I’m not getting anywhere
My Ruby is ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux] on Ubuntu 18.4
I created a bunch of files using a Rails generator (5.2.2) but since ‘rails g’ can’t utilize all the options a migration file is capable of. I need to change_column and add_column and then re-write the file.
Here’s the pertinent part of the modification program:
add_files.each do | add_file |
file_str = “/home/din/Projects/DLC/rails_server/product_exchange/db/migrate/” + add_file
ls_str = "ls -al " + file_str
File.open(file_str, “r+”) do | the_add_file |
Here’s the result:
-rw-rw-rw- 1 din din 90 Jan 21 13:11 /home/din/Projects/DLC/rails_server/product_exchange/db/migrate/20190119232341_add_columns_to_alabama_users_table.rb
Traceback (most recent call last):
4: from /home/din/Projects/DLC/code_ruby/populate_user_table_migrations_01.rb:5:in

Now, as you can see from the output of the ls -al command, the file is there, and it’s readable and writable. The db/migrate directory is also writable by world, but none of the tests find it and it blows up on File.open. I’m running the updater from inside db/migrate, although as you can see the updater now has hard-coded paths everywhere.
Please, somebody tell me this is something trivial and silly!
I’ve tried various IO combinations, various File.open combinations, etc, and I’ve been googling all morning and part of yesterday.
Thanks in advance!
