I was updating error pages to follow latest GDS standard (https://design-system.service.gov.uk/patterns/). I needed to test the 422 page.
After few failed attempts I found this solution to work, just put this code in your index method on your home page:
raise(ActionController::InvalidAuthenticityToken)I hope it helped.
In case you need only alphabetical UUID you can use the following gist. It’s limited to 26 variants which is enough for my needs.
If you ever wondered how to check for file if exist while you were using carrierwave gem with storage on amazon S3 here is how.
Assuming you have User class:
class User < ActiveRecord::Base
mount_uploader :avatar, AvatarUploader
end
and uploader class
class AvatarUploader < CarrierWave::Uploader::Base
storage :fog
end
then only thing that you have to do is this
user = User.first
user.avatar.file.exists?
thats it. I kind of assumed that it should be simple avatar.exist? but you have to get fog instance of file to be able to access exists? method.
To follow my passion which is writing my own applications and running, I decide to leave Unboxed, where I had really great time. I was there almost 2 years and during that time I learn a lot, met lot of interesting people and work on lot of different types of projects. This is list of my projects that I was working on and my role.

Because I started learning Ruby on Rails I needed to run some database server for ruby. I like mysql. I developing web aplications with WAMP (Windows + Apache + Mysql + PHP). So i tried to run Ruby on Rails with pre-installed version of mysql 5.1.33 but Rails didn’t work properly. I tried to find how to fix the problem bud it seems that Ruby on Rails has some problems with mysql 5.1.33.
So i refused SQLite and PostgreSQL for my personal reasons, than only one option left, another mysql server. I downloaded mysql server 5.0. run installation and than configuration that failed in last item (security settings). But mysql server worked quite well.
I was wondering if Rails are going to accept another sqlserver. It didn’t let use say it did but i forget set different port to mysql server 5.0. So i had an idea that this port problem can cause the security problem. So i run configuaration tools set port to 3309 and click to final step and security problem appeared again.Never mind I thought. I added a line port: 3309 as you can see below,
development:
adapter: mysql
encoding: utf8
reconnect: false
database: blog_development
pool: 5
username: root
password: my_passwd
host: localhost
port: 3309
to database.yml in config folder of my project and run rake db:create.
Rails worked fine and WAMP too :).
So in short, you only need to set a different port to run 2 mysql servers at one pc.
PS: It may occur Error mesage like:’ libmySQL.dll missing ‘ or something like that. You will fix this by copy libmySQL.dll from installed mysqlServer 5 directory (installedpath/mysql server 5.0/bin) to your ruby directory (installedpath/ruby/bin).
I has been developing Internet aplication about 9 years. In everyday work i use PHP and AJAX technology. It is quite a long time ago when my friend Ladislav Martincik told me about Ruby on Rails. I seen some amazing presentation of Rails framework he showed me. I wonder why I did not start learning and using Rails and Ruby at that time. Maby it was too early for me or maybe i was too lazy.
But …
I starting now. I bought book Begining Ruby on Rails last week. But the book seems to me that is little confusing. So i was browsing a little and I found this cool book called ‘Poignant Guide to Ruby”. It is kind of unconventional but i love it. It is funny and very brightly written. I’m looking forward to read more chapters tomorow.
Ps: I wonder how high can insects fly, because I live at 8th floor and it still bothers me.
