Put_connections to create a new event with Koala? - ruby-on-rails

Question

I'm trying to create a new event using the Koala gem and it's returning with the same error I got when I tried to update an event with an incorrectly formatted datetime value.
I can update just fine now but still cannot create an event.
Here's the code I use on my update method which works:
start_time = safe_params[:start_time].in_time_zone
end_time = safe_params[:end_time].in_time_zone
graph.put_connections(safe_params[:fb_id], "event", {
name: safe_params[:name],
description: safe_params[:description],
privacy: safe_params[:privacy]
})
And here's the code I'm trying to use to create a new event object:
graph.put_connections("/me/events", "event", { #this is the line that errors
name: safe_params[:name],
description: safe_params[:description],
privacy: safe_params[:privacy]
})
According to Facebook's documentation on creating an event (https://developers.facebook.com/docs/graph-api/reference/user/events/), I should be able to create a new event just by initiating a post to /me/events. Anyone have any idea?
I also tried:
graph.put_connections("/"+current_user.fb_id.to_s+"/events", "event", {
Thanks!

Answer 1

What happens if you do something like this?
graph.put_connections("me", "events", {
name: safe_params[:name],
description: safe_params[:description],
privacy: safe_params[:privacy],
start_time: ...,
end_time: ...
})

Answer 2

So after messing with Facebook's Graph Explorer and attempting hundreds of different combinations with put_connections I decided to make a straight graph_call using Koala.
Finally got an ID response back. I almost cried. Thought I'd share with the community in case there's someone else trying to do the same thing.
event_response = graph.graph_call("/me/events",{
name:safe_params[:name],
start_time: safe_params[:start_time],
privacy_type: safe_params[:privacy],
access_token: current_user.oauth_token}, "POST")
safe_params[:fb_id] << event_response["id"]
#event = Event.create safe_params
I make the call in a stored variable event_response because the Facebook Id returned is used in my app.
First thing I found out: despite using "privacy" as the name of the privacy field when GETting from Facebook and saying so in their documentation, "privacy_type" is actually what you want (found this out in another SO post).
The second thing I found out is even though you are authenticated (have a user token) when you make a graph_call you STILL need to pass along the current_user access token along with making a POST graph_call.
Hope this helps someone!
