If you’re running into a rails migration exception, such as:
column “x” of relation “y” already exists
Then you can conditionally run the associated migration in the following way:
YourModel.reset_column_information unless YourModel.column_names.include?("the_column") add_column(:your_models, :the_column, :boolean, :default=>true) end
Of course, it is probably best to address the underlying workflow issues that caused this issue to occur in the first place. However, if you just want to move along to get along – the above is a great solution.
