I have a block like this:
Blah.where(....).each do |b|
# Code here
end
I only want to run this if some_var
is not nil
or empty. Is there a ruby way to do this other than:
if !some_var.nil
Blah.where(....).each do |b|
# Code here
end
end
First of all you might want
unless some_var.nil?
instead.
ALSO you can use an end if
at the end of the block
Blah.where(....).each do |b|
#...
end if some_var
You could look into the AndAnd gem for some inspiration on solving problems with nil. For an overview check out my answer here .
Other then that the probably best way is to do
Blah.where(...).each do |a|
...
end unless some_var.nil?
