Using Match with Regexp-Do not quite understand the formula
Hi Ruby on Rails community!
I am trying to write a program that uses the .match command to find out
if a string contains a certain word-then using that information write a
conditional statement. The issue I am running into is that I am self
teaching myself and do not really know how to properly use this new
found str. method. Right now this is what my code looks like
def your_plans(activity) #want to use a method for this one
if /activity/.match("movie")
#this is where I get it wrong, I am not sure if this is the proper way
to present the match, and if i am #putting the argument in the correct
position.
puts "I love movies too!"
else
puts "why didn''t you see a movie?"
end
end
puts your_plans("Yesterday, I went to go see a movie")
it is super basic, as I am just a starter. I think the rest of my code
is correct, i just cant figure out the match method. If anyone has some
pointers on why certain pieces go where that would be really helpful. I
have been using this site to look up and learn methods.

thanks!

I removed the "/" around activity, but when i put everything in my code. I am receiving a syntex error. def welcome(activity) if activity.match("movies") puts "Yes, Movies are awesome!" else puts "why don''t you like movies?" end end puts activity("I like going to movies") What i am looking to get in the output is either a "Yes, Movies are awesome" if .match finds "movies", or "why don''t you like movies?" if .match is unable to find movies in the statement. I am thinking it still has to do with me not setting up the argument and .match correctly. thanks, Alex -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Make the last line read as this: puts welcome("I like going to movies") and you will see the output you desire.
