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!

Take the slashes off of activity, and this should just work.

Hi Walter,
Thanks for your quick reply. 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

Your method is called welcome(), but you are calling activity(). Make
the last line read as this:
puts welcome(“I like going to movies”)
and you will see the output you desire.
