Do .. unless

Ruby
1

is there any better way to write that :

if !params[:qaddress].nil?
cond_b = EZ::Where::Condition.new :properties do
…
end
end

using a do… unless ? something like that ??

     cond_b = EZ::Where::Condition.new :properties do
	...
     end  unless params[:qaddress].nil?

how about:

unless params[:qaddress].nil?
cond_b = EZ::Where::Condition.new :properties do
…
end
end

Yeah it only gets rid of the if!, but I think it’s more readable

Maybe this (untested):

params[:qaddress] and
cond_b = EZ::Where::Condition.new :properties do
…
end

Kind regards

Would work if nil were the only thing evaluating to false, but there are
certain instances of the FalseClass, you know :wink:

cond_b = EZ::Where::Condition.new :properties do

...

end

Kind regards

Well, the unless modifier works here – if qaddress is nil, cond_b is
set to nil. Here’s another way:
cond_b = if params[:qaddress]
EZ::Where::Condition.new :properties do
…
end
end

begin # do stuff end while false will be done once
