Calling a Method From a String With the Method's Name in Ruby
How can I do what they are talking about here, but in Ruby?
How would you do the function on an object? and how would you do a global function (see jetxee's answer on the post mentioned)?
EXAMPLE CODE:
event_name = "load"
def load()
puts "load() function was executed."
end
def row_changed()
puts "row_changed() function was executed."
end
#something here to see that event_name = "load" and run load()
UPDATE: How do you get to the global methods? or my global functions?
I tried this additional line
puts methods
and load and row_change where not listed.
Answer
To call functions directly on an object
a = [2, 2, 3]
a.send("length")
# or
a.public_send("length")
which returns 3 as expected
or for a module function
FileUtils.send('pwd')
# or
FileUtils.public_send(:pwd)
and a locally defined method
def load()
puts "load() function was executed."
end
send('load')
# or
public_send('load')
