Ruby array only storing last item during collect statement

Question

I have a ruby method that queries a array through a search. From what is typed in the searchbar it appends that item to another array that shows on the screen. Below is my method:

@churches = ["UGBC", "Oak Ridge Baptist", "Calvary"]
@search_results = []


def search_for(text)
  @churches.collect do |church|
    if text == church
      @search_results << church
    end
  end
end

When the code is triggered the only object that is returned when searched is the last object in the array: "Calvary". If you search any of the other items it sends back an empty array. I have tried an each statement and a collect statement and nothing will work. How do I get it to append to the empty array with no matter what item I search on?

Answer 1

You are not using the right method. I think Array#select is what you need. Also you might have to do a substring check for the text.

Here is an example

text = 'Ridge'

> churches.select{|c| c.include?(text)}
#=> ["Oak Ridge Baptist"]
