3779 - Adding validation to form entries and sticky fields - Ruby on Rails
So far, we have implemented an MVC application under Ruby in Rails, and provided a rudimentary form to allow the user to add rows to the model. In this section, we show you the extra code needed to validate the data, and to echo it back out to the user within the form if it's incorrect. 1. In the m ....

3778 - Providing a form to allow the user to add data to the model - Ruby on Rails
So far, we have implemented a single model - view - controller application using Ruby on Rails, and displayed the data in several forms. How do we add new data? We need to provide an "add product" form, and code to handle that form when it's submitted. Building on the example so far, here's how: A ....

3777 - Multiple views in a single appication - sharing common parts of the template - Ruby on Rails
So far ... we have installed Rails, and written a simple application with a single model, controller and view. In this article, I'll show you how to add a second controller method, and view, while sharing much of the view template. The example takes the scenario of a database of products where yo ....

3776 - Some traps it's so easy to fall into in designing your web site
"Vegetarians' can obviously be catered for" ... obviously. Don't know why they bother to tell us ... "I hope they haven't paid a lot of money for this" says Lisa, pointing me at the web site of a hotel that's not in Melksham, but is "near" according to their definition. I hope they haven't - or tha ....

3775 - Alan Turing - 1912 to 1954
I probably wouldn't be where I am today without a man who died a month before I was born. And who would have been 100 years old today. Alan Turing, one of the legends of modern computing, is also (alas) remembered as a 'cause celebre' in the mistreatment of its citizens by the UK legal system and go ....

3774 - Melksham - a new dawn
Sunrise over Melksham this morning - 23rd June 2012 at 05:05. View taken from our upstairs back window. I love living here and in this town. We may grumble a bit at times, but we've got a lot going for us and the people are great. And just at the moment there are so many things going on that could ....

3773 - Ruby on the web - a simple example using CGI
I've added a CGI example in Ruby - as part of the Ruby training I was doing yesterday. Source code is [here] to show how it works / "Proof of concept". In practise, I would use the cgi module in Ruby if I was doing server side work using CGI - "Hello World" using that module is [here], or if ....

3772 - Hello World - Ruby on Rails - a checklist of each step
Ruby on Rails is a framework under which web applications written in Ruby can be run on a web server, via a browser. You could make your own applications from first principles, but Rails does most of this for you already, so it's typically going to be a huge resource saving for you as you write and ....

3771 - Fine evening, country walk from Melksham - pictures
For a couple of brief months in the summer, it's light enough after a day of training to go for a good walk in the countryside ... as we did on Tuesday evening down to The Barge at Seend. It's about 3 miles from out training centre and hotel at Well House Manor to "The Barge". The first mile ....

3770 - Sample answers to training course exercises - available on our web site
In order to consolidate knowledge that we've just imparted during each module of our courses, we set exercises for the delegates to try out at the end. And we're around and available while they're doing the exercises to check and assist in re-explaining any vital points that they've missed, and to ....
