Rake database migrate failing with "undefined method `double`"

Question

I've defined a scaffold with some of the sqlite columns having type double. When I run rake db:migrate, it gives the following error:

undefined method `double' for #<ActiveRecord::ConnectionAdapters::TableDefinition:>

Is there another way to specify a double that Rails will understand? Should I be using a float here?

Here's the scaffold command:

rails generate scaffold shop name:string latitude:double

Answer 1

Try using float instead of double. Take a look here.
