How to get rid of array after .map method

I am instantiating a variable like so:

Searches Controller:

@search_results = Business.near(params[:search_zip], params[:radius]).to_a

Searches View

<%= @search_results.map do |sr| %>
  <%= sr.business_name %>
<% end %>

=> PetStore FoodStore BeautyStore ClothingStore ["\n", "\n", "\n", "\n"]`

How can I get rid of the array at the end?

You should change from .map to .each since you aren't trying to change the value of the array. You should be able to fix with this:

<% @search_results.each do |sr| %>
  <%= sr.business_name %>
<% end %>

The <%= means you want to print the value

The array is printed because you are using <%= instead of <%. Change

<%= @search_results.map do |sr| %>
  <%= sr.business_name %>
<% end %>

to

<% @search_results.map do |sr| %>
  <%= sr.business_name %>
<% end %>

map returns the evaluation of the block. The returned value is then printed because of <%=.

Also note you don't need a map, each is sufficient and will save you resources in this case:

<% @search_results.each do |sr| %>
  <%= sr.business_name %>
<% end %>

Change <%= to <%

<% @search_results.map do |sr| %>
  <%= sr.business_name %>
<% end %>
