When uploading images Paperclip is saving files wo/ extensions. I'm using ActiveRecord
photo.rb (model):
require "sinatra"
class Photo < ActiveRecord::Base
include Paperclip::Glue
attr_accessible :image
has_attached_file :image,
:styles => {
:small => "100x100#",
:medium => "500x300"
},
:path => "#{settings.root}/public/system/:class/:attachment/:attachment/:id_partition/:style/:filename"
end
photos.rb (controller):
post "/photos/?" do
params[:photo][:image] = params[:photo][:image][:tempfile] if params[:photo][:image]
#photo = Photo.new(params[:photo])
if #photo.save
{ :status => "OK"}.to_json
else
{ :status => "NOK"}.to_json
end
end

I'm trying to create a new ad creative with the following HTTP request
response = HTTParty.post(
"https://graph.facebook.com/v2.9/act_#{account_id}/adcreatives",
:query => {
:ad_format => "DESKTOP_FEED_STANDARD",
:access_token => #ads_access_token,
:creative => {
:object_story_spec => {
:object_id => page_id,
:link_data => {
:call_to_action => {
:type => ad_cta,
:value => {
:link => ad_url
}
},
:link => ad_url,
:message => ad_text,
:description => ad_description,
:name => ad_headline,
:picture => ad_image_url
},
:page_id => "233558376717908"
}
}
}
)
But unfortunately I keep on getting the following error:
{"error"=>
{"message"=>"Invalid parameter",
"type"=>"OAuthException",
"code"=>100,
"error_subcode"=>1487930,
"is_transient"=>false,
"error_user_title"=>"Promoted Object Is Missing",
"error_user_msg"=>
"Your campaign must include an ad set with a selected object to promote related to your objective (ex: Page, URL, event). Please update your ad set to continue..",
"fbtrace_id"=>"DpnhEGhLaSj"}}
I did set up a promoted object for the adset, but I don't understand what it has to do with the adcreative.
Thanks!
I am posting images to LinkedIn through the public api with my app that pulls the images from our S3 bucket. When the update appears on LinkedIn it shows 's3.amazon.com' next to the image. Is there any way that I can keep this from happening?
Ruby Code from app:
def post(message_body, attachment, post)
options = { :visibility => { :code => 'anyone' } }
if attachment.present?
options.merge!(:content => { :title => 'titles',
:description => 'descriptions',
:submitted_url => 'http://s3.amazonaws.com/...'
}, :comment => message_body)
else
options.merge!(:comment => message_body)
end
response = client.add_share(options)
post.posted!
JSON.parse(response.body)['updateUrl']
rescue LinkedIn::Errors::UnauthorizedError => e
raise SocialProfile::UnauthorizedError, e.message
rescue LinkedIn::Errors::AccessDeniedError => e
raise SocialProfile::UnauthorizedError, e.message

My panier.rb:
class Panier < ActiveRecord::Base
belongs_to :user
def paypal_url(return_path)
values = {
:business => 'r.karoui-buyer#loganddrive.com',
:cmd => '_cart',
:upload => 1,
:return => return_path,
:invoice => id
}
line_items.each_with_index do |item, index|
values.merge!({
"amount_#{index+1}" => item.price,
"item_name_#{index+1}" => item.book.title,
"item_number_#{index+1}" => item.id,
"quantity_#{index+1}" => 1
})
end
"#{Rails.application.secrets.paypal_host}/cgi-bin/webscr?" + values.to_query
end
end
my details.html.erb: where i call the PayPal service
<%= #panier.book_id %> | <%= #panier.price %> | <%= link_to 'acheter' , #panier.paypal_url(paniers_path) %>
but I got this error:
undefined local variable or method `line_items' for #

I want to check for an existing record by matching either title or url fields. If either one matches, update that record. Otherwise, insert.
How do write the following properly (using Mongoid in Ruby):
articles.update(
{ **:title => story.title OR :url => story.url** },
{ :title => story.title, :url => story.url, :source => story.source, :last_updated => Time.now },
{ :upsert => true } )
Thanks!
You need do the request and update it like :
'''
articles.any_of({:title => xxx}, {:url => yyyy}).update( :foo => 'bar')
'''
So I have been trying out several different ways to connect my iPhone app to my ROR restful backend and all seems to work ok pulling down data (json) with 'get' requests, but when posting I am unable to do so. I have tried ObjectiveResource and two or three others and they all have the same issue. I am thinking its something set wrong in my ROR app? I did notice all the example iPhone projects use https for production apps, does a production app need to https for an iPhone to establish a session and be able to post?
HERE is what I get for an error if I use http://localhost:3000/posts

Iphone call:
// CRUD methods using Resource.h
- (void)createRemote {
NSString *url =
[NSString stringWithFormat:#"%#/posts", siteURL];
[Resource post:[self params] to:url];
}
%#/posts is equal to http://localhost:3000/posts
Do you have protect_from_forgery set on your ApplicationController?
This essentially kills POSTing information from anywhere except the forms on your website. Try commenting it out and see if things start working.
As peterjb said, check for forgery protection. If you're on rails 3 then look for the csrf_meta_tag in your application.html.erb.
https -- is not must, it is how your server configures for the security needs. You can have http and https both no issues.
I suggest you to have look at the log in ROR app end too know what you get HTTP POST data -- if you are not able to get any data in ROR app end post some code which does POST request from your iPhone, people can analyse it better.
