Hi Eduardo,

Have a look at http://canvabadges.herokuapp.com/ - which lets you do exactly that.

Hope this helps,

Paul

Hi Paul

Your tool looks great and its exactly what I am looking for. 

BUT - after I follow your instructions, I click on the Badges link in the Module and I get this:

{"message":"invalid client_id"}

What have I done wrong?

Thanks

I do not completely understand how the badges system works. Badges are authentified by the twitter account of the instructor ?

I was able to reproduce this issue locally. I'll look into it and follow up with you.

[Louise Munnoch]

Thanks Paul. I'm barely techno literate, so I always assume it's me first, and technology second. I appreciate you taking the time to look into this for me.

Remi,

Canvabadges uses LTI to integrate with Canvas, which means you need a key and secret to make the installation happen correctly. You log in to the Canvabadges site using Twitter to retrieve a key and secret, but that is all and is really just a lightweight way for me to make sure the system doesn't get abused. The *real* user authentication actually happens using the Canvas logins of you and your students.

Louise, are you running your own instance of canvabadges or using the heroku instance? I've updated the github readme (https://github.com/whitmer/canvabadges/blob/master/README.md) to include the configurations you'll need in order to make your own instance of Canvabadges work.

The "invalid client_id" message is actually a Canvas error message, since the first thing that Canvabadges does on initial launch is tries to get an oauth token on behalf of the current Canvas user. It's saying that the configuration is off or has been disabled.

-Brian

[Clayton Morrow]

Brian, 

THANKS!  I had been playing with setting up our own Canvasbadges server this week and kind of hit a roadblock when it came to the authentication after getting it running locally (which was an ordeal in itself, but that's just because I know very little about ruby apps in general).  I'll definitely be following these instructions tomorrow when I'm back to work.

[dan...@blinkmobile.com.au]

I've installed my own instance of CanvaBadges on Heroku (http://blinkmobile-canvabadges.herokuapp.com/) and I receive the following error whenever I open the page:

"Domain not properly configured. No Organization record matching the host blinkmobile-canvabadges.herokuapp.com"

I'm new to Ruby so I imagine it's something on my end that I've forgotten to set (like an environment variable). If you/anyone could point me in the right direction, that would be great.

Thanks!

[Brian Whitmer]

There's a little bit of a change in the newest push. Let me update the docs... again. I need to stop forgetting to update those :-). Should be up to date now. Email me personally if you still have questions or problems.

Hey Brian, 

In trying to run your hosted version of CanvasBadges, configuring it on our system and adding it to a module, I get an error when trying to open it: server refused connection.  I am assuming this probably has to do with ports needing to be opened up for inbound communication, as we're using AWS.  Do you know what I need to allow?

Thanks, 

Clayton  

[Brian Whitmer]

Hm, I've always run it in heroku, so I don't know that I'll be much help getting it going on plain AWS. I'm not much of an backend/ops guy :-/.

-Brian

[Irsandi Hasan]

whitmer,

i've still get stuck with : {"message":"invalid client_id"}

howto solve this error ?

[Brian Whitmer]

Irsandi, do you have a developer key from the instance of Canvas you're trying to authenticate against? When a user first launches Canvabadges it runs through the oauth flow of Canvas to get an API key on behalf of the user, which is needs to check progress toward badge completion. This error usually happens when you don't have a valid developer key from the instance of Canvas that Canvabadges is trying to authenticate against.

-Brian

[Clayton Morrow]

No worries thanks for getting back to me, I was just wondering if there was any plumbing I needed to do to allow any traffic from your heroku app to my canvas install as it doesn't seem to be working.  When configured, my canvas install knows that canvasbadges is thre, but the 'server refused' message seems like maybe it was not getting any replies from heroku.  I think we'll just look into other options for now - we were just looking for some sort of 'course completion' certificate and the badges seemed like they would kind of work.

[Brian Whitmer]

Oh wait, now I'm confused. I thought you were running your own instance of Canvabadges. Now I think you're saying instead that you're running your own Canvas, trying to get it working with my instance of Canvabadges? I think the way it's set up right now that won't work, since Canvabadges needs a developer key and right now it assumes the same one for all instances (i.e. Canvas Cloud). I'd need to add support for multiple developer keys depending on the domain. Still not sure why that would cause a "server refused" message, though..

-Brian

[Irsandi Hasan]

i'm only have key and secret key from canvabadges, howto get developer key ?

[Clayton Morrow]

Ah, gotcha.  Yeah, I definitely didn't describe that as well as I could have, sorry about that. I'll look into running your code on one of our own instances sometime when I get more time.  Thanks for the replies!

[Brian Whitmer]

If you shoot an email to ka...@instructure.com and explain why you need a developer key, that's the current review process.

Hi Whitmer, 

I have several questions to ask about your incredible canvabadges application. :)

I must admit that this is the first Sinatra application that I try to install (I'm rather a "Rails" user) so... maybe some of my questions will seem a little bit odd.

My most important question: 

I've deployed your app on my own dedicated server. I've managed to access it with my browser (with an ugly warning because of the self-signed SSL certificate... but that was expected), I've managed to connect it with my own deployed Canvas application as an LTI application. 

But when I try to access it in one of my course, I've this error: 

OpenSSL::SSL::SSLError at

/oauth_success
SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

With this Backtrace: 

• /usr/local/rvm/rubies/ruby-1.9.3-p392/lib/ruby/1.9.1/net/http.rb in connect

• 101. response = http.request(request)

Did you ever face this issue? 

Do you have any clue why I have this SSL certificate issue?

All my SSL certificates are self-signed, do you think it may be the origin of this error?

Many thanks if you can help me with that. 

Other less important questions:

1. We can set a "DATABASE_URL" environment variable, but what kind of database url can we provide? I mean... I didn't find any way to specify credentials to connect to the database. Is there a way to connect the canvabadges application to an existing Database?

2. In production, we have to set the "SESSION_KEY" environment variable, where would be the best place to set it? (I'm deploying with Passenger and Apache... if it may change anything)

3. I've followed the documentations, and there is this command to execute in an irb console: 

> d = Domain.create(:host => "my_host", :name => "Badges App", :settings => {:twitter_login => true})

But it threw me an error saying that the "settings" attribute isn't accessible for the Domain class. And in the Domain class code doesn't have any "settings" attribute. Did I miss something?

4. I've seen that there is a "revocationList" attribute for the Organization class. What can we provide to this attribute? And what do you use it for?

If you provide me some answers, I'll be glad to add those to a wiki page on your project or... in the readme, if you mind. :)

My apologies if this post is shown twice... 

[Cody Cutrer]

Yes, that error is that it cannot verify your self-signed certificate. I believe you can get past this by adding the public key portion of your certificate to the trusted certificates store on your machine. http://turboflash.wordpress.com/2009/06/23/curl-adding-installing-trusting-new-self-signed-certificate/ has a nice overview of how to that on a Linux machine.

Not sure how much help I'll be, since the reason I use heroku is because I don't like dealing with server configs :-), but I'll answer what I can.

Other less important questions:
1. We can set a "DATABASE_URL" environment variable, but what kind of database url can we provide? I mean... I didn't find any way to specify credentials to connect to the database. Is there a way to connect the canvabadges application to an existing Database?

I can't help here, this is one of the things heroku does for me.

2. In production, we have to set the "SESSION_KEY" environment variable, where would be the best place to set it? (I'm deploying with Passenger and Apache... if it may change anything)

Same, heroku makes my life easier.

3. I've followed the documentations, and there is this command to execute in an irb console:
> d = Domain.create(:host => "my_host", :name => "Badges App", :settings => {:twitter_login => true})

But it threw me an error saying that the "settings" attribute isn't accessible for the Domain class. And in the Domain class code doesn't have any "settings" attribute. Did I miss something?

Shoot, that's wrong. I'll update the docs. Here's what you should run instead:

d = Domain.create(:host => "badgemagic.yourdomain.com", :name => "Name Of Your Badging Thing")

o = Organization.create(:host => "badgemagic.yourdomain.com", :settings => {

  'name' => "Name Of Your Badging Thing", 

  'description' => "I just really like badging!",

  'twitter_login' => true,

  'url' => 'http://badgemagic.com',

  'image' => 'http://badgemagic.com/images/90x90.png',

  'email' => 'admin_or...@badgemagic.com'

})

4. I've seen that there is a "revocationList" attribute for the Organization class. What can we provide to this attribute? And what do you use it for?

Revocation list is a placeholder, since the URL is part of the badging spec. Basically it allows a badging system to revoke badges after they've once been awarded. It's about 20% implemented, and if it's important I can look at adding it, it just hasn't been a priority for me personally.

Sorry I'm not more help! Maybe someone else knows more about Sinatra db config and env variables.

Hello Brian,

I've installed my own canvas open source.

I've try to add canvasbadge using app center.

I've key and secret get from https://canvabadges.herokuapp.com/

I've add external tools to module.

when i click the badge link in module, i'm still get : {"message":"invalid client_id"}

check to error_reports but no error i get.

my question :

this app for open source version or premium version ?

if this app can be used with open source version, why i'm still get this error ?

thank you.

[Brad Humphrey]

Right now the version of canvasbadages that is hosted at https://canvabadges.herokuapp.com/ only connects with cloud canvas.  If you want to run canvasbadges on a open source version of canvas, you will also have to host your own instance of canvasbadges.

[dan...@blinkmobile.com.au]

I imagine it's a bit of a long shot; but could you detail what needs to be done in order to get a hosted version of canvasbadges working? I've got a hosted (open-source) version of Canvas, as well as my own instance of CanvasBadges running, and I'm receiving the same "invalid client id" error.

Thanks!

[Brad Humphrey]

Here are the steps that I think you need to follow to get this working:

• Issue a developer key and secret in your hosted canvas instance at /developer_keys.
  
• Key name and redirect uri are the only required fields.
• Redirect uri should just needs to be the url for your canvas badges instance
• Follow the instructions on github (https://github.com/whitmer/canvabadges#setup) for specifying  the 'canvas_oauth' config, using the developer_key and secret that you generated in step one.

Just to double check, can you verify that the after the tool launches it is redirecting to your instance of canvas for oauth?

Hi! 

Actually you did help me! :)

As it's true that we have to defined SESSION_KEY/DATABASE_URL at the server level on Heroku, I've made some searches and found a way to define those thanks to passenger. I'll explain how for others! 

The idea is to set up a file exporting those variables and to make passenger load this file on startup. Actually it is quite simple! Here is a step by step:

- Create a file named "set_environment" (or whatever) in the root folder of your project and define there your variables like so (for canvabadges):

export DATABASE_URL="postgres://username:password@hostname/database_name"

export SESSION_KEY="your_secret_chain"

And save the file! 

- Next create one other file, that would be conventionally named "ruby_wrapper". This little wrapper will only load the "set_environment" file + execute ruby: (I recommend using the "which ruby" command from the canvabadges project root to know the path to your ruby binary). 

#!/bin/sh

source /path/to/project/set_environment

exec "/path/to/your/ruby"

Once it's done, don't forget to remove those two files from your versioning manager (like git) as they contain some sensitive information. Then you have to add the "execute" right to the ruby_wrapper file. (sudo chmod u+x ruby_wrapper). 

- The last step is to tell passenger to use this ruby wrapper when it launches the server for this application. I've set it that in my VirtualHost, like so: 

SetEnv RACK_ENV production

PassengerRuby /path/to/your/project/ruby_wrapper

Then on next restart passenger should load this file and everything should be set up and work as expected! 

Don't forget to create the postgres database that you put in your DATABASE_URL. Here is a starting guide on DataMapper to help you configure the application according to your needs: http://datamapper.org/getting-started.html. You should know that canvabadges is already configured to work perfectly with postgresql (as Heroku uses postgres so does the application ^^). 

One last thing, once you've created your database (in command lines, for instance), you have to initialize it. To do so, you have to launch the irb console from the root folder of the project. To make my life easier, I've created a third file, which I named "ruby_console" and I've put those lines in it: 

#!/bin/sh

export RACK_ENV=production

source path/to/your/project/set_environment

exec "/path/to/your/irb"

Then I added the execution right on it, and I now just have to launch it ./ruby_console to have an irb console with the expected environment variables. (Again do not include it in git). Then the:

> require './canvabadges.rb' 

Command should go through without any problems. Then you just have to launch: 

> DataMapper.auto_migrate!

To initialize your database. (All the tables will be created with correct columns). Be warned, auto_migrate will wipe out existing data. Use "auto_upgrade!" if you already have some datas in your badge database... 

And that's it!

I hope this little how to will help others! 

Would you mind if I add it to the documentation of canvabadges? Or in the wiki? 

[dan...@blinkmobile.com.au]

Hi All,

I've managed to get CanvaBadges working, which is amazing. So a quick thanks to everyone who helped out! :)

But! I'm having an issue with issuing badges manually. When trying to issue a badge to a person, the application requests access to my account (as it did the first time I opened it up), I click accept/login, and it seems to refresh the page without making any changes.

My previous post (which was deleted) had an error message saying "Configuration not Found". However, I realised the code hasn't been updated in ages, so I pulled the changes from the git repo and while it removed the "Configuration not found" error; it gives me the behaviour above.

Any help would be greatly appreciated!

Thanks,

Daniel

[Stressmagnet]

Hi Daniel, I'm also having this issue. I've got Badges being awarded automatically which is awesome, but when I try and award them manually, I get an error.

Can anyone shed any light on this issue? I'm hopelessly untechnical, and a whole lot lost.

thanks folks!

[Jeremy Schichor]

I'm running into some trouble setting up Canvabadges--can anyone help me out?

I first tried setting it up on our test server, and when I went to the badge page it displayed "Error retrieving badge status" where the status should be, and "Loading failed" under the student list. Firebug shows a response of "<h1>Internal Server Error</h1>" for the status request to herokuapp.

I then gave it a shot on our production server (in a sandbox course). On production the status message comes up as "ERROR: value too long for type character varying(256)". The student list does load, but if I try to manually approve any student, I am prompted for oAuth authorization and when I grant it nothing else happens--the student remains unapproved.

On both test and production, badges are not granted to student who have met the criteria, no matter what permutation of badge settings I try.

Any help anyone can provide would be appreciated. Thanks!

Jeremy.

[Brian Whitmer]

Jeremy, I think I've found the problem. The column for the badge URL was a varchar(256), which doesn't work for some URLs and won't work for any data-uris for sure. I've updated the column table. I'll push the change up to github later today, including migration notes for anybody who's running their own canvabadges.

Anybody running their own, I've added a bit more functionality over the last week, so for sure check out the readme. I'm trying to get to the point where you can manually award badges without having to place them as an item in modules (so, for example, you could make a generic "Good Discusser!" badge and then award it to any students in any of your courses). Not quite there yet, but getting close.

Did anyone have user guide howto installing canvabadges in heroku ? or Installing Canvasbadges in own instance like ubuntu server.

Please help me with this. thx a lot.

[zq...@umich.edu]

Hi, I hope someone will help me out here:

I am downloaded the opensource canvas, and have it running locally.

I went to https://canvabadges.herokuapp.com/, logging to my Twitter account, and got the key, secret and URL for Canvabadges. 

Then I went to External Tools and added new app for the Canvabadge with Configuration Type of "by URL" and paste in my key and password. I have saved the configuration correctly without error. The tool is marked with Resource Selection and User Navigation Extensions type.

The following is the traces I can find in the Canvas log file:

Processing ExternalToolsController#update to json (for 127.0.0.1 at 2013-12-11 16:00:13) [PUT]

[0bd730076686acd916afe42aa430419d 272d1dc0-44d5-0131-8ea8-14109fdc9d39]   Parameters: {"consumer_key"=>"<key>", "created_at"=>"2013-12-11T20:48:25Z", "description"=>"Easily award badge credentials to students who meet course completion criteria", "domain"=>"", "id"=>"6", "name"=>"Badge3", "updated_at"=>"2013-12-11T20:48:27Z", "url"=>"https://canvabadges.herokuapp.com/placement_launch", "privacy_level"=>"public", "custom_fields"=>{}, "workflow_state"=>"public", "vendor_help_link"=>nil, "user_navigation"=>{"url"=>"https://canvabadges.herokuapp.com/placement_launch?custom_show_all=1", "text"=>"My Badges", "enabled"=>"true", "label"=>"My Badges", "selection_width"=>800, "selection_height"=>400}, "course_navigation"=>nil, "account_navigation"=>nil, "resource_selection"=>{"url"=>"https://canvabadges.herokuapp.com/placement_launch", "text"=>"Canvabadges", "selection_width"=>800, "selection_height"=>500, "enabled"=>"true", "label"=>"Canvabadges"}, "editor_button"=>nil, "homework_submission"=>nil, "custom_fields_string"=>"", "shared_secret"=>"<secrect>", "config_type"=>"manual", "config_url"=>"", "config_xml"=>"", "action"=>"update", "controller"=>"external_tools", "format"=>"json", "course_id"=>"1", "external_tool_id"=>"6"}

However, when I try to add the tool to Canvas module, it pops up an empty window with "sad face" icon in the middle.

I cannot find any error message in the log file.

Any suggestions?

Thanks,

- Zhen

[zq...@umich.edu]

Now that if I change the Privacy setting of the CanvaBadge external tool from "Public" to "Anonymous", I got the following error after adding the tool into module:

This app appears to have been misconfigured, please contact your instructor or administrator. App must be launched with public permission settings.

powered by Canvabadges

What is the correct setting of Privacy for CanvaBadge tool?

Thanks,

- Zhen

[Brian Whitmer]

Zhen, I haven't heard of a sad face error, but Canvabadges won't work with more than one Canvas instance at a time. The heroku instance you're talking about it tied to Canvas Cloud, so it won't work with your open source instance of Canvas. That *might* be the reason you're getting the error that you are. Canvabadges is open source, though, and should be easier to get up and running than Canvas itself, so there's that route.

I do want to add multitenancy to Canvabadges, but I haven't gotten to that yet.

Hope that helps!

-Brian

Hi, Brian:

Thanks for your reply. I will download open source Canvabadges and try it later.

Thanks,

[Brian Whitmer]

Zhen, I just looked at the code and it looks like I lied to you, it is possible for my heroku instance to talk to your Canvas install. I added support for it a little while ago and just didn't tell anybody (and forgot about it myself). I just need some additional information from you. If you want to try it out shoot me an email directly and I'll send you what I need from your side (basically I need a developer key generated on your instance of Canvas).

Thanks!
