This correctly evaluates to true because the relation contains one
returned record.
However, I run the same query within the Rails app itself, and any?
must evaluate @drivers in the view to either false or nil, because the
else is triggered instead when I click on second page in view. What's
even weirder is that when I call inspect on @drivers, then
@drivers.any? is evaluated to true in the view when I click on the
second page using kaminari:
@drivers = Driver.select(drivers.*, #{sort_column})
.joins([:reports, :driving_habits])
.by_month(for_selected_month.to_i,
for_selected_year.to_i)
.order(sort_column + + sort_direction)
.page(params[:page]).per(1)
puts The drivers #{@drivers.inspect}
What's driving all this weird behavior?
Can you show us the code where you perform the test that is failing?
