Is there a way to download a generated excel file in a Ruby on Rails application?
After a user clicks on a link, I want to generate an excel file in the backend and have it formatted correctly. However, when I use remote: true in link_to, the file doesn't get downloaded even after the generation process is complete.
What steps can be taken to successfully download this file?
If you want to achieve the same functionality without using remote: true on the link/button, you can simply modify your link/button like so:
<%= link_to "Export as CSV", your_thing_path(@your_thing, format: "csv") %>
Additionally, include the following code in your controller:
respond_to do |format|
format.csv {
send_data(render_to_string(layout: false),
type: 'text/csv; charset=iso-8859-1; header=present',
filename: "my_export.csv")
}
end
By implementing these changes, you can achieve the same outcome as using remote: true. You can still trigger actions based on the link click while having the flexibility to incorporate presentation-level JavaScript in your view.
