Hello,
where do we need <% -%> in templates ? What is the difference between
<%= %> and it ?
<%= %> will execute the contained ruby and inject the result into the
document.
<% %> will execute the contained ruby, but will NOT inject anything
into the document (other than a blank line) … hence …
<% -%> will execute the contained ruby and will not inject anything
into the document (not even a blank line).

Thank You, Derrick!
You can also use - with the include. I.e.
<%= “blah” -%>
This will inject “blah” into the output, but will not create a new line.
This is useful when you’re pulling data into something that is
surrounded by quotes (like an HREF) where you don’t want the newlines
and want to maintain readability.
