Hello, basically i want to change the self object inside a proc so i can
do a thing like this:
the_proc= lambda { @variable }
class Test1
def initialize proc
@variable= 1
# Here i need to bind somehow the proc to the instance of Test1
puts proc.call # should emit 1 from @variable
end
end
class Test2
def initialize proc
@variable= 2
# Here i need to bind somehow the proc to the instance of Test2
puts proc.call # should emit 2 from @variable
end
end
Test1.new
Test2.new
That’s only an example. The real need is because of a rails application
in wich i pass a proc that is going to be evaluated in one of the
controller’s helpers:
customers_link_builder= lambda do |resource, helper|
helper.instance_eval do
link_to "Ver clientes", customers_path(resource)
end
end
If I could bind the proc to the helper i could do better like this:
customers_link_builder= lambda do |resource|
link_to "Ver clientes", customers_path(resource)
end
That would be very nice!!!
Thank you!
