*2018 rails: undefined method `each' for nil:NilClass

error code

    undefined method `each' for nil:NilClass

my products controller code

    def index
      #@products = Product.all
      @products = Product.where(gender: 'male').take
    end

html.erb code

    <% @products.each do |product| %>
    <h3><%= link_to product.title, product %></h3>
    <p>On sale by <%= product.user.name %></p>
    <% end %>

I get an error when I try to use the second query, but the first one works (Product.all) works fine. I have looked at many other problems like this and cannot solve it. Can anyone help?
