Working with Rails as a designer

J June, 2012 /

Installing Rails

You have to install first ruby, rubygems, git, bundle, rails

Installing ruby

Preferable way is to install it with normal user via rvm. I am not an expert in mac so probably you need to install xcode from your disks/Internet. Then use rvm

Here is a one of the many tutorials http://www.shanison.com/2011/02/20/how-to-install-rvm-on-mac/

here are other ways for installing ruby taken from Ruby on Rails for Designers

  • Windows: One-Click Ruby Installer (I recommend using 1.8.6-26 Final Release)
  • Mac OS X 10.4: Ships with broken Ruby but you can follow the amazing guide by Dan Benjamin
  • Mac OS X 10.5: If you install the Developer Tools from Apple you will be set. Try either your installation discs or Apple’s Developer Site and download Xcode
  • Linux: While this may vary for each distribution, you will need to install ruby, irb, & rdoc

Installing rubygems

Download, extract and run ruby setup.rb

more reading here http://docs.rubygems.org/read/chapter/3

Checkout the project

One SCM is git. install it

http://git-scm.com/book/en/Getting-Started-Installing-Git

Then checkout it

git clone ssh://par@gudasoft.com/uppstart

Starting Rails project

go to the project folder you have checkout already.

cd uppstart

rvm will ask you if you trust the version of ruby specified in the project. Please agree and install it if you don’t have it.

installing is done by

rvm install ruby-what-ever-version

then you have to install bundle. This is done by doing

gem install bundler

After you have install bundler you will have the bundle command available. Bundler will try to install all the project dependencies. do this by typing

bundle

if you don’t have errors you will be almost ready to run the application.

check in config/database.yml and prepare the database specified in the development section

cat config/database.yml

If you see in development sqlite3 as an adapter then just type

rake db:setup

start the application by running

rails s

check the app by navigating to http://localhost:3000

Views

All views are located under app.

Files starting with underscore are partials which are reused in multiple places.

Assets

Assets could be in several places.

check

  • app/assets – for assets which are from the application
  • lib/assets – for assets which are exported
  • vendor/assets – for 3rd party assets

If you want to add your own file include it under the

application.js

or

application_screen.css

Do not add css/javascript directly in those files.

Deploying the application

Put your ssh keys on the server. This should be done once.

Then you have to put your changes on the remote repository. This is done by doing

First we need to get any remote changes by doing.

git pull
git commit -a

Then we can add our new files and commit the changed files/folders.

add the new files with

git add filename_or_folder

then commit all with a message

git commit -a -m "nice message what was changed"
git push

Finally From the application folder run

cap deploy

uptimed and uprecords

J September, 2011 /

Nice! As I am maniac of  uptime here is nice utility found at http://www.linuxjournal.com/content/tracking-server-uptimes

uptimed. It is similar to the utility that most of us have heard of, uptime, except that it runs as a daemon and logs the system’s uptime instead of just reading info that is lost on a reboot. Uptimed provides a secondary command called uprecords

If you have a lot of readings then Struct is the winner.

If you have equal read/write then Hash

And forget for OpenStruct

Here is why and how I benchmark all those methods

Rails tip of the day

Generating random string

ActiveSupport::SecureRandom.hex(16)

Autoicrement the serial in bind zone files

J September, 2010 /

Argh. 30+ zone files and I have to increment all numbers by hand…no way.

Usage:  ./inc.rb in the current directory with all db files.

#!/usr/bin/ruby

Dir.glob("*.db") do |file_name|
 new_zone = [] Continue reading

Wireframing for faster website development

J August, 2010 /

I have tried the approach listed in “Getting Real” by 37signals and I have great results.

The client was very happy because he can imagine his website.

Now I am considering to buy or make such nice tools :)

http://www.uistencils.com/website-stencil-kit.html

http://www.mstonerblog.com/index.php/blog/comments/return_of_the_paper_wireframes/
1. Pencil

Pencil (free) is a Firefox plugin that professes to enable you to build wireframes and prototypes. As a prototyping tool it’s quite good, allowing you to quickly put together a reasonably high fidelity mockup. However, be aware you’ll still need to produce the visual design elements for Pencil, as it relies on dragging and dropping pre-made graphical elements.

The output wireframe elements that ship with Pencil do tend to be based on the look and feel of a Windows desktop application. This really is undesirable for a web application, however you could modify this with your own page elements.

Another downside of Pencil is that its export functionality provides only a few image formats. This means that Pencil falls short of being a real interactive prototype development tool.

Balsamiq Mockups

Balsamiq Mockups (price:$US79, demo available) is an interesting product running on Adobe AIR. Its representation of the interface elements has a refreshing hand-drawn, sketch-like quality to them. This does help promote the degree of changeability of the wireframes, as they look very much like a draft. If you lack the skills to create hand-drawn sketches then Balsamiq is a useful tool, as it allows you to produce quality roughs. Balsamiq also offers a standard collection of interactive screen elements, which is helpful to start off with.

http://gomockingbird.com/ is like balsamia

https://www.jumpchart.com/ – for very simple pages- I cant find how to change the layout.

Software development

J August, 2010 /

After my blog post about the junior software developers I have very bright idea of how the world could get benefit from them.

When you catch a junior in mistake – let him contribute to the open source community. Not with coding. With translating. Take some open project and translate it to your native language.

Maybe after all the junior will release that he is much happier to translate than coding :)

win-win condition.

N.B. On the picture – Young coder is coding in Word.

Is Rails going down?

J August, 2010 /

The first Rails framework was fast. then it become slow, big and the idea of convetion over configuration becomes more poisoned.

Currently to start with Rails you have to learn a lot of stuff which are added just now and is not sure how long they will stay.

Also Rails is not targeting the developers to be fast but is targeting to be the perfect framework.

The price for that is that almost a year and a half there is no new version while the they refactor it.

No goodies like scafolding, only enterprise stuff around.

That is my personal opinion on this framework.

As I like to say – you cant leave your followers without food for such long time.
