“Handling File Uploads in Ruby on Rails”

In⁢ the code snippet above, we use ‌the form_with helper to create a form⁢ for the “Upload” model. Inside the form, we ​have‌ two​ fields: ‌one for ⁢the “name” attribute ‌and⁤ another for the ‍”attachment” attribute.‍ The ⁣form.file_field method allows users ‍to ⁤select⁤ a file for upload.

Controller: Handling the Upload

Now, let’s move on to ​the controller to handle the file​ upload. Open the file “app/controllers/uploads_controller.rb” and add the following code to the “create” method:

In the code⁤ snippet⁤ above, we access the uploaded file using params[:upload][:attachment]. We then open ⁣the⁤ file ⁢in write binary ⁤mode and‌ save‍ it to the “public/uploads” directory. Note that you may need​ to ​create the‌ “uploads”‍ directory manually in the⁢ “public” folder.

Showing the⁤ Uploaded File

Finally, let’s update the⁣ “show” view ‌to display the uploaded‍ file. Open the file⁢ “app/views/uploads/show.html.erb” and replace ​its contents with ‍the ​following code:

In the code ⁢snippet ‌above,‌ we ⁣use⁢ the image_tag helper to display ⁤the uploaded file‍ as ‌an image. The path to the file is ⁤constructed‍ by concatenating “/uploads/”‍ with the original filename of the ‍uploaded file.

Conclusion

With the⁣ steps outlined above, you can​ easily ​handle file uploads in Ruby⁣ on Rails. Remember to handle any ⁢additional⁣ validation or security considerations ⁣as per your‌ application’s‍ requirements. Good luck with your file‍ upload feature!
