What are Rails partials and how do I use them?

Rails partials are reusable view templates that help you keep your code DRY (Don't Repeat Yourself). You can use them to render shared content across different views.

Can you show me an example of how to create a partial?

Sure! To create a partial, you can create a file named _form.html.erb in your views directory. You can then render it in another view using <%= render 'form' %>.

How do I pass local variables to a partial?

You can pass local variables by using the locals option. For example: <%= render 'form', locals: { user: @user } %>.

What are some best practices for using partials?

Some best practices include keeping partials small and focused, naming them clearly, and avoiding too many nested partials to maintain readability.
