What are the best practices for using partials in Rails?

Using partials in Rails helps keep your views DRY. Best practices include naming conventions, keeping them small, and using locals.

Can you explain the naming conventions for partials?

Sure! Partials should be prefixed with an underscore, like _form.html.erb, and placed in the same directory as the view.

How can I pass data to a partial?

You can pass data to a partial using the locals option, like this: <%= render 'form', local_variable: value %>.

Are there any performance considerations I should be aware of?

Yes, rendering too many partials can impact performance. It's best to limit their use and consider caching when necessary.
