Rails - Sep 2005 - HOW: short if statement?

hey, how is the short if statement?? cuz otherwise i need al lot of pages, 
and i want to keep a good overview


something like this in php
-------------------------------
$lening[$i]->bedrijfsbeheer ==
0?$tpl->setVariable("bedrijfsbeheer_value",
""):$tpl->setVariable("bedrijfsbeheer_value",
"checked" );

===>> the ..... ? ........ : .... ; way

but for rails:
-----------------
if params[:client][:country].blank?
	@country =""
else
	@country =  params[:client][:country]
end

Exactly the same format:

@country = params[:client][:country].blank? ? '''' :
params[:client][:country]

Looks a little odd with the 2 question marks, but should do the trick.

it''s almost identical as in PHP:

params[:client][:country].blank? ? @country = "" : @country
params[:client][:country]

or even shorter:

@country = params[:client][:country].blank? ? "" :
params[:client][:country]

Can''t you also do:

@country ||= params[:client][:country]

I don''t think that works in this case. ||= means set @country only if
it''s currently nil. Since @country will always be nil at this point in
the code, it''s just like using =.

If params[:client][:country] will never be nil, then there''s no need
for a conditional:

@country = params[:client][:country]

If there''s a possiblity that it could be nil, then the following will
work:

@country = params[:client][:country] || ""

Assuming params[:client][:country] is either nil or a real value, how
about just:

@country = params[:client][:country].to_s
