embedded ruby syntax “<%= .. %>” in rails [

问题:

This question already has answers here:

What is the difference between <%, <%=, <%# and -%> in ERB in Rails? (7 answers)

<% %>(without equal) in ruby erb means? [duplicate] (3 answers)

Closed 5 years ago.

Am I correct with the idea below regarding ERB template? any advice would be really appreciated.

Is the embedded ruby syntax with an equal sign "<%= %>" intended to render some output? while the one without the equal sign "<% %>" doesn't.

回答1:

When you use <%= %> you render the expression value to your output. While <% %> is simply to write some Ruby code that won't be rendered to final output.
