Passing Boolean Parameters in Ruby on Rails
The My Ruby on Rails function should get a boolean parameter, check it, and if it's true, do something.
def isReady
if (params[:ready] == true)
doSomething()
end
end
However, in the example below, we never get inside this if (but it is part of the function), probably because the parameter is passed as a string and not as a boolean. How can I properly pass boolean parameters or convert them?
curl --data "ready=true" http://example.com/users/isReady

Right. The way I handle it in ruby way is as follows:
class String
def to_b()
self.downcase == "true"
end
end
Now any string will have a method to_b
. You can write
def ready?
if params[:ready].to_b
do_something
end
end
