Fist time setup

Writing a test

Running your tests

$> ruby -Itest test/unit/recette_test.rb

Troubleshooting

If you are on an large existing project and are just starting writing your tests you may face a couple of walking on broken glass debugging.

Problem: DELETE FROM non-existing tables

ActiveRecord::StatementInvalid: SQLite3::SQLException: no such table: friends: DELETE FROM "friends"

Let's check the log test.log

...
Fixture Delete (0.0ms) DELETE FROM "friendrequests"
Fixture Delete (0.0ms) DELETE FROM "friends"
SQLite3::SQLException: no such table: friends: DELETE FROM "friends"
...

The solution is surprisingly to remove a file from the test/fixture folder

Problem: INSERT INTO a table that has no column named 'XYZ'

This is due to your fixture deriving from your models schema. The solution is to fix your fixtures files.

In my case the solution was to change this for that :

The post Unit tests in Ruby on Rails appeared first on Techy Things.

Before (wrong)

 private
 def user_params
   Rails.logger.info("PARAMS: #{params.inspect}")
   params.require(:user).permit(:fullname, :login, :password, :password_confirmation, :phone_home, :phone_work, :phone_cell, :deliveryNote, :home_address_attributes).require(:home_address_attributes)
 end

After (good)

  private
  def user_params
    Rails.logger.info("PARAMS: #{params.inspect}")
    params.require(:user).permit(:fullname, :login, :password, :password_confirmation, :phone_home, :phone_work, :phone_cell, :deliveryNote, 
      { home_address_attributes: [ :line1, :line2, :country, :zipCode, :province, :city ] })
  end

Solution

Downgrade from

gem 'sunspot_rails', '= 2.2.6'

to

gem 'sunspot_rails', '= 2.2.0'

or upgrade your solr.xml configuration

The post Solr failure appeared first on Techy Things.

Solution

Downgrade from 3.5.0 to 3.4.5 !

Modify Gemfile with

gem 'authlogic', '~> 3.4.5'

And run again:

$> bundle install

(...)
Using scrypt 2.1.1 (was 3.0.3)
Using authlogic 3.4.6 (was 3.5.0)
Bundle complete! 21 Gemfile dependencies, 80 gems now installed.

The post Authlogic You did not provide any details for authentication appeared first on Techy Things.

$> sudo dd if=/dev/zero of=/swap bs=1M count=1024
$> sudo mkswap /swap
$> sudo swapon /swap

To make permanent, add this line to /etc/fstab

/swap swap swap sw 0 0

Install Passenger

$> gem install passenger
$> apt-get install apache2-threaded-dev libapr1-dev libaprutil1-dev
$> passenger-install-apache2-module

At the end it will display for you what to add to apache global conf file, in my case :

LoadModule passenger_module /usr/local/lib/ruby/gems/2.1.0/gems/passenger-5.0.30/buildout/apache2/mod_passenger.so
 <IfModule mod_passenger.c>
 PassengerRoot /usr/local/lib/ruby/gems/2.1.0/gems/passenger-5.0.30
 PassengerDefaultRuby /usr/local/bin/ruby
 </IfModule>

Also put something similar to this in the virtual host Apache config :

DocumentRoot /home/cbuy/public_html/public
RailsEnv production
ErrorLog /var/log/virtualmin/community-buy.ca_error_log
CustomLog /var/log/virtualmin/community-buy.ca_access_log combined
ScriptAlias /cgi-bin/ /home/cbuy/cgi-bin/
ScriptAlias /awstats/ /home/cbuy/cgi-bin/
DirectoryIndex index.html index.htm index.php index.php4 index.php5
<Directory /home/cbuy/public_html/public>
allow from all
AllowOverride All
Options FollowSymLinks -MultiViews Indexes
</Directory>

Restart Apache

Troubleshooting

Generic error

Check where you can access the log file with

$> passenger-config --detect-apache2

"We're sorry, but something went wrong."

Edit Apache VirtualHost configuration to run development mode to see the error:

RailsEnv development

Then restart Apache.

"This web application process is being run as user 'nobody' and group 'nogroup' and must be able to access its application root directory"

chown your app dir so that your user can access it. If you use virtualmin that is your domain account user.

Problem: Only accessible on localhost

chown -R <user>:<user> /home/<user>/public_html

Problem : It doesnt work

Solution

RAILS_ENV=production bundle exec rake assets:precompile
