Futnotes – setting up the repo

Cloning the repo

git clone devtest

Mixtures of errors doing bundle install though
First it is capybara

Using capybara (1.1.2) 
Installing capybara-webkit (0.12.1) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

According to these sources thoughtbot and stackoverflow qt need to be installed first, before install capybara.
To install qt, you must link to libpng, simply link to linpng will fail due to permission,

Error: Could not symlink file: /usr/local/Cellar/libpng/1.5.13/lib/pkgconfig/libpng15.pc
/usr/local/lib/pkgconfig is not writable. You should change its permissions.

To fix that

sudo chown -R kahfei /usr/local/lib/pkgconfig

then only follow by command below

brew update
brew link libpng
brew install qt

bundle install still fail though

An error occurred while installing rmagick (2.13.1), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

It seems that lot of people having this same problem. Some of the suggestion work for some people, but none of it fixed my problem. Apparently this is a rmagick bug, as it does not support the newer version of ImageMagick. rmagick has not been updated for two years, so if there is an option, change to other gem to work with image, like minimagick

After hours of scouring the internet, and trying a few different approaches, using the magick-installer to install ImageMagick, then

bundle install

work again. No actually I lie,  bundle install yield another error

ERROR: While executing gem … (ArgumentError) marshal data too short

There are suggestions to remove ~./gem folder altogether and reinstall all the gem. But in my case, bundle install work on other rails apps, just not this one. So I clone again the repo to a new folder, now bundle install work!

Now creating development, testing and production environment. I already have postgresql installed locally, so I will use postgresql, my database.yml looks something like this

adapter: postgresql
encoding: unicode
database: futnotes_development
pool: 5
username: kahfei
adapter: postgresql
encoding: unicode
database: futnotes_test
pool: 5
username: kahfei
adapter: postgresql
encoding: unicode
database: futnotes_production
pool: 5
username: kahfei

now to create them

rake db:create:all

All three database created

rake db:migrate

with a long list of errors, it start with something like this

PG::Error: ERROR:  column "position" does not exist
LINE 1: ...RE "competitions"."name" = 'Premiership' ORDER BY position, ...
