paperclip

Right now I am using Amazon S3 and Paperclip which is allowing my users to upload an image that is associated with the event they are creating. My ultimate goal is since others can view this event, to be able to click on the image and have it prompt a SAVE TO their computer. As of now, clicking the link will open the image in a browser window. I rather have it ask for them to download instead. All images only saved on S3, not local. Need to hide exposed s3 url as well if possible or camouflage it Here is my current setup Index.html <%= link_to 'Download Creative', event.creative.url, class:

How do I rename a file after is has been uploaded and saved? My problem is that I need to parse information about the files automatically in order to come up with the file name the file should be saved as with my application, but I can't access the information required to generate the file name till the record for the model has been saved. If, for example, your model has attribute image: has_attached_file :image, :styles => { ...... } By default papepclip files are stored in /system/:attachment/:id/:style/:filename. So, You can accomplish it by renaming every style and then changing image_file

I have a Rails 3 app with paperclip, with the intent to store data on S3. In the app, Users belong to an instance. I would like the data stored across all the models per instance. And would like to prevent a user from Instance A from accessing, or being able to load data from Instance B. What's the best way to handle this? thanks I actually just implemented authorized S3 url's in my Ruby on Rails 3 application with Paperclip . Let me share how I accomplished this. So what I did, and what you probably want is quite easy to implement. Let me give you an example: FileObject model has_attached

You know on some sites when you're asked to upload, say, an avatar, you click on the button, select your file, then hit OK, but before you Submit the page (as in, no record is created/updated), a little preview of the image shows up? How would I accomplish this using Paperclip for Rails? Bonus points for anyone who can point me towards a tutorial or something that might tell me how to do a Javascript crop on the image before saving the record. I haven't been able to find much on Google on the subject... thanks for the help! This kind of thing is problematic from a Rails perspective because of

I have a model that uses paperclip like this: has_attached_file :avatar, :styles => { :large => "100x100>" , :medium => "50x50>", :small => "20x20>" }, :default_url => '/images/missing-owner_:style.png' I'm exporting this model with to_json method and I want to export the image url so I could use it in javascript. I know I can access the url like this in the view: <%= image_tag model.avatar.url(:medium) %> But How can I do the same in the to_json method. I have some like this: respond_to do |format| render :json => @model.to_json(:only => [:id,:name,:homephone,:cellphone]) end Ben Zittlau I
