Error opening history when no jobs have been submitted

error.log

Hi, if a user clicks "history" in the top menu, but the person hasnt submit any jobs trough the open composer, we get an Internal Server Error. I am attaching the error log. It seems the error is in lib/history.rb script, in the function update_status (line 211). But I don't know ruby so I don't know how to solve this problem. Thanks!

It seems the problem is because /home/user/composer doesn't exist until a job has been submitted through the app. So, conf["data_dir"] = ENV["HOME"] + "/composer", which doesn't exist. I guess that file could also be created in run.rb? But again, since I don't know ruby I'm afraid to add a line of code creating that file in the wrong place.

In the mean while, is there a way we can disable history from the menu while this problem gets solve?

Hi again, I think I solved the issue, I added these lines to run.rb. Please let me know if what I did is not correct. I will try to submit a pull request with these changes if you allow that.

1. Added on top of the file: require "fileutils"
2. Added at the end of create_conf function, right before return conf, FileUtils.mkdir_p(conf["data_dir"])

I'm a bit confused of why fileutils was not require before since there are other lines of the file that call FileUtils. But since I dont know ruby, maybe is not necessary?

Thanks
