Question

I have by mistake given a column in my database a wrong name, so I wish to change it. I have run my:

bundle exec rake db:migrate

I am trying to rename my column with this command:

rename_column(Bankline, appendex_number, appendix_number)

Taken from here:
http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/SchemaStatements.html#method-i-rename_column

However, my Terminal gives my this error message:

-bash: syntax error near unexpected token `Bankline,'

Any ideas? I have already tryed these commands:

rename_column(bankline, appendex_number, appendix_number)

rename_column(banklines, appendex_number, appendix_number)

Answer 1

The answer is on the page you link to:

rename_column(:banklines, :description, :name)
