Creating Facebook Events with an Image

[ssgrfk]

Hey.
Im successfully using Mini FB to create Facebook events from my rails
app. What i want to do now is create those events with a user uploaded
image, or a default image if the user doesnt specify one.
I was able to do this with the old facebook API using Facebooker
using :

fullpath = Rails.public_path + "/images/FBEvent.jpg"
file = File.open(fullpath,"rb")
data = file.read
@image = Net::HTTP::MultipartPostFile.new("Image Name",nil,data)

and then posting the @image after the :params for the Facebook event.

I cant seem to get this working with Mini_FB.. anyone shed some light
on this?

thank you.

Have you tried MiniFB.post with the :picture options?

Sorry i should have been more specific.

How can i create the image, to pass as :picture?

What i was using with Facebooker no longer works. ie

Net::HTTP::MultipartPostFile.new("Image Name",nil,data)

thx

[Travis Reeder]

I believe you want to pass in a File object, someone made a patch for this a while back that accepts File objects.

Could i ask what your code looks like for posting an event (minus the
file)? ive tried a hash and json and all i get are errors like this:

can't convert RestClient::Payload::UrlEncoded into String

event_hash = {"name"=>"Tourdate St. Louis MO US", "location"=>"Fubar",
"end_time"=>1281409200000, "description"=>"This is the description of
the event", "start_time"=>1281398400000}

MiniFB.post(current_fanclub.facebook_page_access_token,
current_fanclub.facebook_page_name, event_hash)

MiniFB.post(current_fanclub.facebook_page_access_token,
current_fanclub.facebook_page_name, :params=>event_hash)

MiniFB.post(access_token,
account_id, :type=>'events', :params=>event_hash)

MiniFB.post(access_token,
account_id, :type=>'events', :params=>event_hash.merge(:type=>'events'))


No matter what i do the same error:

Try with a different date format, like the ones here: http://www.php.net/manual/en/datetime.formats.compound.php

no go.

i even tried using the date (copy/paste) from the sample on the facebook dev site here =>

https://graph.facebook.com/331218348435 so i dont think its the date format.

it also seems that doing any .post call raises this error

>> MiniFB.post(access_token, 'me')

TypeError: can't convert RestClient::Payload::UrlEncoded into String

curious.

GET requests work great:

MiniFB.get(current_fanclub.facebook_page_access_token, 'me')

resp={"id":"124624130883738","name":"RecCenter","link":"http:\/\/www.facebook.com\/pages\/RecCenter\/124624130883738","category":"Local_technology_telecommunications_services","fan_count":3}

=> <#Hashie::Mash category="Local_technology_telecommunications_services" fan_count=3 id="124624130883738" link="http://www.facebook.com/pages/RecCenter/124624130883738" name="RecCenter"

and for reference - this works, using the hyper-graph gem ==> http://github.com/chrisdinn/hyper-graph

>> token = facebook_page_access_token

=>"1400842345358094 |1e88b25657af773e5d1cd98-682730385|13043245686971963|f7887S-V4pk5a24566ahKOVDFk."

>>page_id = facebook_page_access_token.split('|').first

=>"1400842345358094"

>>graph = HyperGraph.new( token )

=> #<HyperGraph:0x108c1a698 @access_token="1400842345358094 |1e88b25657af773e5d1cd98-682730385|13043245686971963|f7887S-V4pk5a24566ahKOVDFk.">

>>graph.post("#{page_id}/events", :name=>"dude", :description=>"awesome", :start_time=>'1215929160', :end_time=>'1215929160', :location=>'the phoenix')   

=>{:id=>122527554461466}

i am at a loss for why i cannot post anything to facebook using mini_fb.

Are you able to post simple messages to a wall?  I just tested it with the mini_fb_demo app here: http://github.com/appoxy/mini_fb_demo and it worked fine.  Let me know if you can do basic messages just to see if it's an event thing.

Travis

[Jerrod Blavos]

ill pull down the app and give it a shot and let you know.

thanks!

[Jerrod Blavos]

message successfully posted from the sample app!

I also added an event posting form to the app for testing that you could pull into your sample app - i know posting events is a huge pain and the interwebs helped little -

http://github.com/indierockmedia/mini_fb_demo/commit/644e977075057e8ea3bafb39146e5ea1159b9bad

the date definitely needs to be an epoch date, which you can get from a datetime object by adding .to_i

and the venue information needs to bot be nested - essentially all params need to not be nested in any sort of way.

so my issue above is going to be application specific, now for the fun part - tracking down what it is....

thanks for your help!
