...into a single dataframe (since the columns are exactly the same for all 46 sheets). The rio package does this nicely, the problem is that, once I have the full dataframe (which amounts to roughly 2.98 million rows total), I cannot change the data type from boolean to numeric. I tried doing dataset$my_field = as.numeric(dataset$my_field), I also tried to do dataset <- dataset[complete.cases(dataset), ], didn't work either.

I started my app before migrations were a best practice and have been using SQL scripts. Now I''m looking at potentially having to move from using MySQL to postgreSQL to use a particular hosting provider. I understand migrations are the way to go to make this ''easy'' but it also looks like the use of migrations introduces extra work in other areas. I''d really

I have a situation in which I want to validate a number is not zero. Both positive and negative values are acceptable, just not zero. validates_numericality_of has an :equal_to attribute, but I don''t see a :not_equal_to.
