Blank White Page

30 Mar 2012, 12:28

I have installed the Ruby Hosting Package, Ruby 1.9 Dev kit, Ruby 1.9, Rails 3. The static index.html page in the public folder of my Rails application renders fine. That file even pulls images from inside of rails engines in my application. However, when I try to hit a controller method, the page renders as a blank white page. If I check the rails log file I see that the method succeeds. If I check the helicon log I see no errors either. So it appears as though helicon is handling ruby requests just fine but that IIS is not outputting the result. Any help is appreciated. I will post the web.config and log files below.

blank page source:

Hello.
Please check what status code and response headers you get from IIS. Please also provide the output of that controller as it must be.
Thank you.

Hi.
Please try and set RACK_ENV variable to “development” in the web.config file: <add name="RACK_ENV" value="development" />
Let’s see if it makes a difference.
It would be nice to have your application, or the relevant part of it, so that I could test. If that’s possible, please send it to support@helicontech.com
Thank you.

I am trying to run Compass AE which is open source: https://github.com/portablemind/compass ... enterprise
FYI, I am using IIS 7.5

To install Compass AE, try this:
gem install compass_ae
compass_ae new [your apps name]

Then I recommend modifying your Gemfile
I am running from github master at the moment as the gems on rubygems are old:
git "https://github.com/portablemind/compass_agile_enterprise.git" do
gem "erp_base_erp_svcs"
gem "erp_tech_svcs"
gem "erp_app"
gem "erp_forms"
gem 'knitkit'
gem 'rails_db_admin'
gem 'compass_ae_console'
end

Then:
bundle update
rake db:migrate
rake db:migrate_data

(using sqlite at the moment to test helicon)

Could you please package the application and send it to us or put on github. I followed all steps you’ve provided and used your web.config files but couldn’t reproduce the issue.

So you are successfully seeing the login page when you hit /erp_app/login?
I zipped up the app but it is 300meg. I think it put all the gems and cloned the repo into vendor/.
I am going to strip that out and try and zip again. Hopefully it will be small enough to email.

Just want to post that I got this working by recreating the website in IIS using the basic Add Website feature. It appears as though the "Blank Rails Project" somehow was interfering with the application to cause the contents of the page to be sent in the header of the response. Very strange.
