I would like to provide a link to download a file via Rails. These are my questions:-
Where do you place the static file under public?
Are there any simple controls which allows me to download this file.
You don't need rails for this. If the file is in public, your web server should serve it automatically.
You just need to know the URL so that you can link to it from your app.
Doesnt really matter where you put it within public, but pick somewhere that will let you keep organized as you add more.

I am trying and failing to download a single file from a "open for public" dropbox folder which a 3rd party created for others to use. I am trying to use this within my Ruby On Rails Application (file is changing but folder stays the same all the time).
I want to:
List all files in that public folder
Make sure that there is only this one file
... and this file has the appropriate filename (ending in .xlsx in my case -> an Excel file)
Download the file (e.g. using RestClient gem)
Save as an attachment to a new database record (Record is existing already and is used inside the app)
Thanks for any hints on how to proceed here! I Than plan to update the file with a cron-job daily.
Its kind of an API to the public :-)
Thought there must be a simple gem to interact with dropbox folders but couldnt't find any.
I used Rest-Client to open the dropbox folder and Nokogiri to parse the content but cant work through the glibberish produced. I gave up after an hour of work and decided to ask here!
Dropbox does offer a public Dropbox API, but it doesn't offer an official SDK for Ruby in particular, but you can either use the Dropbox API HTTPS endpoints directly, or via a third party library if there is one that works for your use case.
Exactly how you would accomplish this would depend on the specifics of the scenario so you may want to read through some guides first to get started, e.g.: Getting Started and File Access.
For instance, depending on how you have access to the content (e.g., directly via a folder in a connected account, or via a shared link, etc.) some of the following endpoints may be useful:

The Dropbox API v2 Explorer can also be a useful tool for trying out Dropbox API calls.
I am developing an iOS app that uses a large amount of images that are needed for animations for short videos. I want to save my application assets as static files in cloud and once they are needed download them using secure API call (either JSON, XML or any other alternative for that matter).
What is the best option for that. I have checked Parse, Dropbox, iCloud, Google Drive, but I am puzzled since I see only instructions for dynamic data that lets users access content they have created and not static assets.
What would be best option for that?
If you just want an easy way to serve static files I would take a look at Amazon S3. You can just upload files through the online console and then get the public URL to those files to use in your app. You can also use the S3 API to upload files through your web service or iOS app.
Hope this helps!
I'd go for Parse (basically because it is fast to learn and develop), you can create a table with the images and change the writing permissions if you are afraid somebody could modify the table.
Another option that you can check it's the special Config table so you can upload custom files (zip files i.e.) and download them in demand.
I'm working with parse.com for my server end. I'm wondering if there's a way for files to be saved into subfolders. For example my file is currently saved with a url like this:
http://files.parsetfss.com/bb2767e6-fc18-4ff5-a071-199803c9aac2/tfss-d056e28e-1e02-49dd-930b-e46790a2e38d-Drums.png
is there a way I can get it to look like this instead:
http://files.parsetfss.com/bb2767e6-fc18-4ff5-a071-199803c9aac2/tfss-d056e28e-1e02-49dd-930b-e46790a2e38d/Drums.png
and for the same extension (tfss-d056e28e-1e02-49dd-930b-e46790a2e38d) apply to each row?
The reason I need this is because I'm actually uploading html files and it can't find its assets if they get renamed...
Have a look at the Cloud Hosting documentation here:

Basically whatever files/folders you put in the "public" folder will be publicly available.
You can use it to upload files you want to be shared normally, instead of the way you described in your question which is for files you want to attach to objects.
There is a lot of information in the title of the question !
I'm aware of Rails gems to upload files, parse Excel, etc. but I would like to know which solution will work nice in a Backbone app (that is, I don't want to reload the page during the upload). Is there a Backbone extension for that ?
The story is: the user wants to upload an Excel file, she browses her filesystem, selects the file, click "upload"... and then the Backbone app shows the content of the file (I don't need to store the file on the server).
Well, i dont think there is any backbone extension for that :) What you need is some upload extension like uploadify of http://blueimp.github.com/jQuery-File-Upload/ . You will bind the
success method to uploader and then you can do anything with the data returned from server.
Basically, this is what my app does:
It sends an AJAX request
The server creates a file
The server sends back the URL of the
file location
The client-side will attempt to
create a dialog to download the file
at that location (probably using a
frame? I haven't got this far yet).
My question is, how do I dynamically route to the files I create so that they are accessible when you browse to them? If I don't add a route for them, then they will get a 404 if they try and access the directory they're in.
The files are currently stored in a folder in public.
Would the best way to deal with this make the folder somehow not require a route, so that it can be browsed to directly, and then have an index page on it so they can't view the full list of files? If so, please let me know how I can accomplish this. And on a side note, if you have an idea of how I can accomplish JS displaying the download dialog let me know.
It's Rails 3 by the way.
Thanks!
For a full private set of files: choose a place for your files outside your public directory, then configure X-SendFile support in your web server and finally use send_file in your rails application.
