products = Product.order(:first_name)

headers = ["Product ID", "Name", "Price", "Description"]

CSV.open(file, 'w', write_headers: true, headers: headers) do |writer|

var jqry = document.createElement('script');
jqry.src = "https://code.jquery.com/jquery-3.3.1.min.js";
document.getElementsByTagName('head')[0].appendChild(jqry);

## Rendering with status and location headers:

All renders take the :status and :location options and turn them into headers. They can even be used together:

```Ruby
 render :xml => post.to_xml, :status => :created, :location => post_url(post)
 ```

Note that the :status option accepts not only an HTTP status code (such as 500), 
but also a symbol representing that code (such as :created), if that makes more sense to you.
