some trouble with rails, capistrano and git

Firstly I had to adjust the HEAD of my bare repo with some brute force like:

git push --force origin 688ec48e36b747b3820d55925268f51978be96d0:master

After my server bare repo was up-to-date again I could go for a closer look at capistrano and deploying my rails app.

Do this on your server to get some idea of the problem:

tail -n 30 log/production.log

It will give you the latest 30 lines of log output.

For me it were two things:
  1. precompiling did not work:

    I had to have a closer look at my deploy.rb etc and found some big mistakes of mine. I precompiled everything and some was already done so it had e.g. sass variables and the compiler collapsed.
    Just try this to see if you app runs fine:

    RAILS_ENV=production bundle exec rake assets:precompile --trace
  2. my server app just had empty sqlite3 files so my migration did not work:

    Log into your server and have a look or do some migrations manually.
    I read this and changed my deploy.rb file so cap deploy:migrate is run everytime:

    capistrano guide

    capistrano tweak

Now my app works fine again, altough I found some other unclean code on the way but after setting precompiling away from the *wildcard* but specific files it worked fine; --trace is your friend.

rails + carrierwavve + plupload = multiple file upload

Right now I am very happy! I finished my work on creating a file upload method in rails for more than one file, altogether handled by rails sessions and as objects. First I had to learn a bit more about how rails works and I achieved that by reading a lot: books, screencasts and blogs. In this blog post I like to share what I accomplished, but without the hussle of putting code blocks in here, so watch out for bold formatted text as that is the code. My goal was to have one site with just the pure option of uploading files. All file handling would be done behind the scenes by myself logging onto my server. That said you are not going to see any fancy CRUD here. Lets start then! And dont forget to versioning your app BEFORE you try something new! [e.g. git] > rails g scaffold Photo title:string Now add carrierwave to you Gemfile and run > bundle install >rails g uploader Photo Alltogether you have model, controller, views and an uploader folder with the Ph...

debian 6 vserver - a new installation due to centOS update problem - my steps

My centOS vserver broke down after a "yum update" and even the centOS community forum could not give an answer within 24h. In my books that is poor for the almighty and stable centOS. Bare in mind that I am just a normal user of linux, no professional and definitely no expert when it comes to server, but I can read, try and share my findings: debian 6 installation steps via ssh secure your server: adduser foobar for security purposes  change /etc/sshd/sshd_conf to PermitRootLogin no now you can login as foobar and change to root via su - visudo for sudo command permissions and put this at the bottom: foobar   ALL=(ALL) ALL change hostname change hostname in /etc/hostname and in /etc/hosts reboot login via rsa key rather than password locally do ssh-keygen ssh-copy-id -i foobar@hostname... ssh now works without passwords but with keys (for easy deployment) install ruby and rails via rvm login as root always good to have: sudo apt-get install...

Virtuelles Wasser?!

In den letzten Tagen habe ich immer mal wieder etwas mit Rails programmiert und werde mich ebenso heute dem neuen Auftrag "multiple file upload" kümmern. Und weil vieles "Versuch-Irrtum" ist, gucke ich auf dem zweiten Monitor immer Reportagen. Letztens kam mir "Der große Haushaltscheck" unter die Finger: ARD Mediathek "Der große Haushaltscheck" In der Sendung vom 11.3.2013 ging es um unser Trinkwasser. Jedem sollte klar sein, dass Plastikflaschen nicht die erste Wahl sind, weil man nicht darauf vertrauen kann, dass der Hersteller wirklich "gutes" Plastik nahm (BPA, Phtalate, Benzol, Xylol usw.), aber das interessante waren die genannten Zahlen in puncto virtuellem Wasser bzw. Wassersparen. Wasser sparen an und für sich ist ja gut, nur heisst das nicht, dass wir weniger die Klospühlung benutzen sollten, sondern dass wir uns Gedanken machen über das "virtuelle Wasser". Unsere Kanalisation ist eine Schwemm-Kanalisatio...
