I'm uploading the image using aws-s3 gem, it uploads perfectly and give me the url. Image is in PNG format but when I hit the public url in my browser, it starts downloading, but I don't want to download it, I want to see the image in browser.
Please tell me if you know which parameter in the following request should be added for this or what change is required to achieve this?
AWS::S3::S3Object.store(base_name,open(local_file),bucket,:content_type => mime_type,:access => :public_read,:authenticated => false)
s3_url = AWS::S3::S3Object.url_for(params[:name],bucket)[/[^?]+/]
Check :content_type => mime_type if mime_type is correct.

My app uploads an image to S3 and returns the URL of that image. However, it returns a URL like http://my-client-dev.s3.amazonaws.com/gifs/export_gif_3_1438603398.gif?AWSAccessKeyId=AKILLV5BH1BNAT3D3D3Q&Expires=1438607003&Signature=SBQmnULXR5F5cAtyZgqbFl0%2Bn%2Fk%3D
How can I get it to return the simple URL that doesn't require access key and signature in the URL? Also, the links expire pretty quickly.
Here is my code:
bucket.objects[filename].write(result.to_blob, {:acl=>:public_read})
url = bucket.objects[filename].url_for(:read, :secure => false).to_s
Have you looked at the S3 SDK? It has a #public_url method.
We are using carrierwave + aws S3 to upload file, and we need provide a download function.
For solution 1, we use:
= link_to "Download", file.doc.url, download: file.original_name
And it does not work under IE8, click the link will open this file(image).
According to This, I should add Content-Disposition header,
Then I check aws S3 document, Found I need add response-content-disposition to file.doc.url,
Is there any way I can do this in carrierwave, or I could use other ways? Thanks for your help.
Got it, for fu = FileUploader.new, we can use:
fu.url(query: {"response-content-disposition" => "attachment;"})
Read tons of documents and source code.
I am developing a website on ruby on rails where users can upload pictures thanks to paperclip, it is stored in amazon S3. After, they can modify pictures thanks to aviary. But when i want to save the new pictures, aviary just gave me an temporary URL where i can get my modified picture.
Does paperclip can do it ? I don't think it can save an picture from an URL and store it to S3 ?
I've searched for a week now, and i don't know the best way to do it. I've read about filepicker, but the account to store data in S3 files isn't free ...
Finally i've heard about this s3 https://github.com/qoobaa/s3, but i don't understand how to use it. I have installed gem s3, but when i set require 's3' , it is not recognize.
What is the best to do?
Why don't you pass the URL that Aviary generates to your server and upload the new photo from there? The code below does that in Python/Django:
#login_required
#csrf_exempt
def upload_from_url(request):
origin_url = request.POST.get("origin_url")
name = request.POST.get("name")
try:
conn = boto.connect_s3(settings.AWS_ACCESS_KEY_ID, settings.AWS_SECRET_ACCESS_KEY)
bucket_name = settings.AWS_UGC_STORAGE_BUCKET_NAME
bucket = conn.get_bucket(bucket_name)
k = Key(bucket)
k.key = name
file_object = urllib2.urlopen(origin_url)
fp = StringIO.StringIO(file_object.read())
k.set_contents_from_file(fp)
return HttpResponse("Success")
except Exception, e:
return HttpResponse(e, mimetype='application/javascript')
Hope this helps.
Paperclip has matured a lot since this question was answered. If you want to save files by passing a URL, as of Paperclip v3.1.4, you can just assign the URL to your Paperclip attachment attribute.
Let's say I have a class User and my attachment is called avatar. We'll have the following in our User model:
has_attached_file :avatar
# Validate the attached image is image/jpg, image/png, etc
# This is required by later releases of Paperclip
validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/
In our view, we can define a hidden field that will accept the temporary URL received from Aviary:
= f.hidden_field :avatar, id: 'avatar'
We can set the value of this hidden field with the Aviary onSave callback:
var featherEditor = new Aviary.Feather({
apiKey: '#{ENV['AVIARY_KEY']}',
onSave: function(imageID, newURL) {
var img = document.getElementById(imageID);
img.src = newURL;
var avatar = document.getElementById('avatar');
avatar.value = newURL;
featherEditor.close();
}
});
Within onSave, you can use AJAX to update the User object, use jQuery's .submit() to submit the form, or let the user submit it when they want.
I have a problem with S3 and CarrierWave:
I have a pseudo-form that uploads data and files, I wrote "pseudo" because it's an ajax form so data is sent with jquery to rails with a POST request. Files cannot be uploaded in this way...so I have a popup windows that upload files to rails, I save in the session the reference to the uploaded files and when the ajax request uploads the rest of the form, I link the files uploaded to the rest of the data.
With storage :file it works without any problems, when i receive the file I do:
uploader = ImgObjUploader.new
uploader.store!(params[:image_form][:image])
session["image"] = uploader.url
and then when I get the rest of the data:
if (session[:image] != nil) then
obj.image = File.open(session[:image])
end
And my model is:
mount_uploader :image, ImgObjUploader
This code work without any problems, for amazon s3 I switched to:
uploader = ImgObjUploader.new
uploader.retrieve_from_store!(session[:image])
puts uploader
#obj.image = uploader
obj.image = uploader.url
but it doesn't work...I didn't receive an error but I don't have the image saved inside obj object. Puts uploader prints the url of amazon S3.
Anyone can help me?
Thank You.
I followed the following blogpost to figure out how to create Facebook events remotely using my app. I've been having problems loading the images from my app, however, because I do not have images stored locally on my app, they are stored in AWS.
#graph = Koala::Facebook::GraphAPI.new(#token)
picture = Koala::UploadableIO.new(#event.photo.url(:small))
params = {
:picture => picture,
:name => 'Event name',
:description => 'Event descriptio
:start_time => datetime,
}
is the following code I am currently using to send pictures to Facebook when Facebook events are created on my app. The problem is, however, that Rails is throwing the error: No such file or directory - http://s3.amazonaws.com/ColumbiaEventsApp/photos/21/small.jpeg?1312521889.
Does anybody who's more experienced with Rails development know if there is a way for me to treat a URL like a path to a file? The UploadableIO class expects a path to a file, and I'm struggling to figure out if there's a way in Ruby to treat URL's like filepaths. The way that photos stored on the app can be loaded to Facebook is as follows:
picture = Koala::UploadableIO.new(File.open("PATH TO YOUR EVENT IMAGE"))
if that helps.
I appreciate any new insights into this issue.
Ok so I played around and figured out how to post pictures.
Basically what I did was use the 'open-uri' library to convert the image links into file objects, which can then be passed to UploadableIO and sent to Facebook. This is the code that worked:
require 'open-uri'
OpenURI::Buffer.send :remove_const, 'StringMax' if OpenURI::Buffer.const_defined?('StringMax')
OpenURI::Buffer.const_set 'StringMax', 0
picture = Koala::UploadableIO.new(open(#event.photo.url(:small)).path, 'image')
params = {
picture: picture,
name: #event.name,
description: #event.description,
location: #event.location,
start_time: datetime
}
#graph.put_object('me', 'events', params )
The OpenURI constant StringMax needed to be changed because the image files I was using were small enough that the files were being processed as Strings rather than File Objects.
Hope this helps anyone trying to fix this!
With Koala 1.2.1 it's a very elegant solution. Here is sample code for creating an album and uploading to it from a remote, AWS link (btw this took about 30 lines in PHP w/ the PHP SDK!
#foo = Foo.find(params[:foo_id])
albuminfo = #graph.put_object('me','albums', :name=>#foo.title)
album_id = albuminfo["id"]
#graph.put_picture(#foo.remote_image_path,{}, album_id)
Facebook recently released an update that lets you post pictures using publicly accessible URLs (http://developers.facebook.com/blog/post/526/). The Koala library you're using supports that (https://github.com/arsduo/koala/blob/master/lib/koala/graph_api.rb#L102), so you should be able to post the pictures you're hosting on S3 without having to use OpenURI::Buffer.
For Facebook Ad Images, you unfortunately currently cannot do it by URL, thus:
require 'open-uri'
img_data = open(my_post.image.url :medium).read
img = graph.put_connections('act_X', 'adimages', bytes: Base64.encode64(img_data))
