I have a rails 3 app that has a comment system that allows a user to make comments. What I now wish to do is extend this further by enabling the user to attach/upload files to the comment system. Fairly easy question I am about to ask. What is the best tool/plugin or gem to use so that I can achieve this? I've done some thorough research and found that alot of these plugins such as carrierwave, paperclip and a few others are used to upload photos and I am not trying to do this.
Requirements
User should be able to upload/attach files
Can upload word, powerpoint or execel docuements
Both carrierwave and paperclip can be used to upload any type of files - they have extra features if you want to upload images, but they are not restricted to handling just image files.
In the end it's a matter of preference. I found both paperclip and carrierwave to be very good at what they do.
Paperclip
CarrierWave
As for me CarrierWave more modern and nice solution. Have a try.
You can use even dragonfly - https://github.com/markevans/dragonfly/

I am developing a Rails application and I want to upload a picture directly from my browser using Cloudinary.
I followed all steps from the Cloudinary page and ended up with a box and a question mark after I "uploaded" it, no picture at all. Any ideas what might be the problem?
I am not sure what you have used. But you should use carrierwave with cloudinary. Cloudinary having some complex way to handle display and save image if you don't use carrierwave.
But carreirwave provide simpler way to achieve uploading and display image.
Without using carrierwave
Using carrierwave in compbination
You should try the sample project and then check the differences:

Thanks!
I'm a complete beginner but I'd like to know even in a generic way so that my users could upload a file to another user's directory, the file gets saved on to a server and the receiving user could download it when the upload gets finished.
Since you're a complete beginner, I won't give you a lot of code; instead, I'll show you the overview of what you can do, and hopefully that will give you a much more refined approach to adopt:
Rails Uploads Using Paperclip
What makes Rails so powerful is the gem ecosystem - these are little plugins which give you functionality outside the scope of the Rails framework. You can get Gems for everything from file uploads to CSS frameworks - all for free
One of the most important & popular gems for Rails is Paperclip (and you have Carrierwave which also does the same job). These are what you use to process image uploads in Rails
Since you're a total beginner, you should really watch this Railscast about how to upload files with Rails using Paperclip:
There are also a lot of other tutorials on Paperclip:
Heroku's Paperclip Tutorial
Simple Paperclip tutorial
Another Paperclup tutorial
I would write some more updates about Paperclip & JQuery, but I think you should get your head around the upload process first
Normally I'd use carrierwave, but they do not officially support jruby, and I've been running in to bugs, possibly related. (https://github.com/jnicklas/carrierwave/issues/620, Image corruption on upload to s3, production only. (carrierwave, engineyard))
Have others had success here?
I'm considering trying out paperclip, but it looks like that may not be perfect either-- https://github.com/thoughtbot/paperclip/issues/100
Try dragonfly it's a really great library to manage you file attachment.
check out this guide, it's cake
http://webtempest.com/how-to-allow-image-uploads-in-rails-on-heroku/
It uses paperclip and amazon web s3 gems
I have a requirement of uploading a file to my disk through my webpage. Seems like I have two options
My requirement is specific that I will upload ONLY text files.
Using default rails methods to upload a file.
Ex: http://www.tutorialspoint.com/ruby-on-rails/rails-file-uploading.htm
Using a plugin like 'PaperClip'
Following are my concerns:
I want to keep the file upload as simple as possible
Keep as away as dependencies like Imagemagic etc
I'm using rails 2.8.3
concurrent file uploads can be happen by multiple users
please can someone tell me what are the pros and cons of having
writing a simple file upload (option 1)
using a plugin/gem to upload a files
Writing your own file uploader is an option, but using a pre-built gem provides you with all of the code you need, straight after install.
Gems will usually have all of the functionality packaged into them that handles all of the cross-platform issues and security headaches your likely to run into by writing something from scratch. A well maintained gem will also have a good community behind it, keeping things up to date.
The popular Gems out there are really easy to use, and unless you are resizing images etc, you shouldn't need ImageMagick installed. Have a look at these:
http://railscasts.com/episodes/134-paperclip
https://github.com/technoweenie/attachment_fu/wiki
Paperclip is far easier to build a simple upload form with, but I'm not sure if it works on Rails 2. Attachment_fu is an old favorite from the Rails 2 days and will definitely be able to handle your problem, it just requires a little more configuration.
How do I upload images and zip files in RoR? I am a newbie. So please help.
Give me both the view and the controller code example.
Thanks in advance.
Nav,
Try the paperclip plugin, you can read about it here http://www.thoughtbot.com/projects/paperclip
We prefer CarrierWave for image uploads in Rails. Very easy to integrate and very modular.
The following post describes a solution for image uploading using CarrierWave while image transformations are done seamlessly in the cloud. Uploaded images are stored in the cloud and delivered through a CDN.
No need to install RMagick, MiniMagick and ImageMagick.
http://cloudinary.com/blog/ruby_on_rails_image_uploads_with_carrierwave_and_cloudinary
suggest checking out the Railscast for paperclip.
ImageMagick is also pretty cool
I would recommend paperclip, and the patch that allows you to store the content in the database instead of the file system
http://patshaughnessy.net/paperclip-database-storage
the link has the view and controller examples that you are looking for
I prefer carrierwave is better to upload images easily.
Here's github page , and railscasts page for quick start.
One option is attachment_fu. It allows you to save your uploaded file to the filesystem, database, or Amazon S3. It also allows you to select which image processor is used, such as RMagick or Minimagick.
The link provides better code than I could here.
