render partial rails

To render a partial in Ruby on Rails, follow these steps:

1. Create a partial file with the underscore (_) prefix in the views directory, for example, _partial.html.erb.

2. Add the HTML or Ruby code that you want to reuse within this partial file.

3. In the main view file, use the render method to include the partial, specifying the path to the partial file without the underscore, for example, <%= render "partial" %>.

4. Optionally, you can pass local variables to the partial by using the locals option in the render method, for example, <%= render "partial", locals: { variable_name: value } %>.
