Setting a var in the view

Rails

How do you set a variable in the view? I need to setup a counter, I
have a query that loops through its records, I need to set the count to
1 and increment the counter each time the loop occurs.

It would be a lot better just to just records.size, because the info’s
already there.

Anyway, you can do
<% counter = 1 %>
<% records.each do |r| %>
<% counter += 1 %>
… other stuff
<% end %>

Your best way is to use each_with_index, for example

<% @users.each_with_index do |user, index| %>
User #<%= index+1 %>. <%= user.username %>

<% end %>

That seems to work well for me :slight_smile:
