I'm testing how to mount several apps in camping, and I am following these instructions. I have this structure:
more/apps/
pm.rb
qm.rb
Both apps just return the index view with some text. When I startup the server, the index shows the pm's index when the address is http://localhost:3301/.
If I try http://localhost:3301/pm, I get this error:
Camping Problem!
/pm not found
Same error for qm. Am I missing something?
This does not work anymore. camping now only accepts a single file. You can still mount multiple apps, but you need a single file that requires them:
# in apps.rb
require 'pm'
require 'qm'
And then you can run:
camping apps.rb
I'm not sure how to do this yet but in the issues on camping github they mentioned using a config.ru like you would for any Rack app.
I hope this helps.

I am trying to setup and use omniauth-ebay-oauth (https://github.com/evilmartians/omniauth-ebay-oauth) gem to use eBay rest APIs in my app without success.
I set up the required environment variables and run the example code but get a message saying "Sinatra doesn’t know this ditty.". It does not recognise the '/auth/ebay' route, not sure if I have to declare that route myself nor what to put in it if I do. I'm new to ruby and Sinatra so do apologise if this is just something silly and obvious that I'm missing.
require 'omniauth-ebay-oauth'
use Rack::Session::Cookie
use OmniAuth::Builder do
provider :ebay_oauth, ENV['EBAY_CLIENT_ID'], ENV['EBAY_CLIENT_SECRET'],
callback_url: ENV['EBAY_RU_NAME'], name: 'ebay'
end
get '/' do
redirect '/auth/ebay'
end
get '/auth/ebay/callback' do
"Hello, #{request.env['omniauth.auth'].dig('info', 'name')}"
end
I appreciate any help and insight in getting this working. I've googled everywhere and asking here as my last resort.
I opened an issue on the GitHub repository and the gem creator replied in 3 hours. Totally life saver. I will post the solution here to help others.
It is because of security settings of OmniAuth 2.x.
Add the following line at the top, after requires:
OmniAuth.config.allowed_request_methods += %i[get]
This worked like a charm and I can now move forwards with the project.
I've been trying to tackle this all morning. Locally, this setup works just fine. I am not using the redactor-rails gem because this is a rails 4 app and it doesn't support it. I have moved the redactor.css and redactor.js calls from the active_admin initializer file to be required in my actice_admin.js.coffee and active_admin.css files because on Heroku, it could not find the path. Now, when firing up the page that should be displaying redactor, I get has no method 'redactor' in the console.
I'm at a loss. I've read up on precompiling assets and the how the pipeline works, but it doesn't seem like I'm doing anything out of the ordinary here.
So how can I deploy to Heroku without this error?
Ok, so I seemed to have disregarded an important task. After thinking about precompilation a bit more I remembered I had been told to run
RAILS_ENV=production bundle exec rake assets:precompile
before. After running that again, it precompiled the active_admin.css and active_admin.js.coffee files which had the new require's in it. Viola!
Hope this helps someone else in the future.
I'm new with Rails and I'm having trouble understanding why the following error occurs. I have a page where I've linked a pdf file and some images for download.
In the view:
link_to( image_tag('image.png'),:controller=>'home',:action=>'download', :file_name => 'image.pdf') %>
In the controller:
def download
send_file "#{RAILS_ROOT}/assets/pdf/#{params[:file_name]}", :type=>"text/pdf"
end
When I try to download the file in the development environment I get the following error:
No route matches [GET] "/assets"
I've tried changing the path to the file and searching on google and SO. I imagine this must be a relatively simple fix and probably has to do with the asset pipeline but if someone could point me in the right direction, I'd be very happy.
Hey there I ran into this issue myself and the solution for me (rails 2.0.2) was to put the pdf file into the public directory of your application and make a direct link www.yoursite.com/my.pdf this will execute the download right away.
Why is this?
well once you deploy your app the rake assets:precompile will be ran and therefor the assets will appear in your public directory.
You can also do this local by running
$:. rake assets:precompile RAILS_ENV="development"
Although I would not advice commiting these files.
I'm working on a ruby app that updates a twitter account using 'twitter' gem. It's working fine locally (as usual :) ). But when I deploy it on heroku it seems the gem is not properly installed or something lile that as I got the following error:
NameError: uninitialized constant Twitter::OAuth
My code is very simple:
oauth = Twitter::OAuth.new(consumer_token, consumer_secret)
oauth.authorize_from_access(access_token, access_secret)
client = Twitter::Base.new(oauth)
client.update("Updating my status from twitter gem. GREAT!")
Is there a problem with this particular gem ?
Thanks a lot for your help.

Have you created a .gems file and put twitter in it?
Depending on which heroku 'stack' you are on, you may need to do that instead of a bundler Gemfile. You can change your stack for one that uses bundler by doing this:
heroku stack:migrate bamboo-ree-1.8.7
Which makes bundler available (I think).
That is a common message that usually implies that you have a discrepancy between your local gems and the gems in heroku. If you are not using Bundler yet, you should. You will end un writing a very simple Gemfile that will tell Heroku (or any other entity using your code) which gems and versions you require.

I would suggest that you should use the heroku addon called 'apigee', ut makes twitter on heroku simple:
http://addons.heroku.com/apigee
I just got a sinatra app talking to Twitter through Heroku/Apigee, my rate limit went from 300 calls per hour to 20,000 calls per hour. Here's a step by step on what to do:

I am really a Java developer just playing around with Sinatra but let me know if I can help in anything.

This is my first time asking a question, please be gentle!
I have a Rails application that handles content for a whole bunch of domains (over 100 so far). Each domain either points to where my app is hosted (Heroku, if you're interested), or the original place it was hosted. Every time a domain is ready, it needs to point to the heroku servers, so that my app can serve content for it.
To check to see if a domain has successfully been changed over from its original location to my application, I'm writing a script that looks for a special hidden tag I included in them. If it finds the tag, then the domain is pointing to my app. If not, it hasn't been changed, which I record.
The problem is that, at least for one domain so far, I'm getting a 404 OpenURI::HTTPError exception for my script. Which is strange, because I can visit the site just fine and I can even get it via curl. Does anyone know why a working site would get an error like this? Here's the important snippet:
require 'rubygems'
require 'open-uri'
require 'hpricot'
...
url = "http://www.#{domainname}.com"
doc = Hpricot(open(url)) #<---- Problem right here.
...
Thanks for all of your help!
Welcome to SO!
Here would be my debugging method:
See if you can replicate in irb with open-uri alone, no Hpricot:
$ irb -rubygems -ropen-uri
>> open('http://www.somedomain.com')
Look in your Heroku log to see if it even touches the server.
Look in your original server's log for the same.
Throw open something like Wireshark to see the HTTP transaction, and see if a 404 is indeed coming back.
Start with that, and come back with your results.
