dry

Unless I'm missing something (which is very possible), it seems to me that custom validation has always violated DRY. In all the examples I've seen, even with the brand new Unobtrusive Client Validation introduced w/ MVC 3, we have to create .NET code for our server-side validation, and jQuery (or JavaScript code) for client-side validation. I understand that there's no such thing as a .NET-to-jQuery translator that would facilitate DRY server/client validation, and I guess that would be the only way to have true DRY validation that works both server and client side. But I would be perfectly

anybody know how to implement dry-run option in Ruby? I need something like this, but only for ruby https://serverfault.com/questions/147628/implementing-dry-run-in-bash-scripts I've tried this, but part after else doesn't work: DRY_RUN = true def perform(*args) command = args if DRY_RUN command.each{|x| puts x} else command.each {|x| x} end end perform("puts 'Hello'") Thanks for any idea in advance. P.S I don't want use something like system ("ruby -e \"puts 'Hello'\"") This could help: def perform(*commands) commands.each { |x| DRY_RUN ? puts(x) : eval(x)} end It results in: DRY_RUN = true

I created this class <?php abstract class Validator{ public $_errors = array(); abstract public function isValid($input); public function _addErrors($message){ $this->_errors = $message; } public function getErrors(){ return $this->_errors; } public function getMessage(){ return $this->message; } } class Validator_NoSpaces extends Validator{ public function __construct($value){ $this->isValid($value); } public function isValid($value){ if (preg_match('/\s/', $value)){ $this->_addErrors("Spaces are not allowed"); return false; } return true; } } class Validator_MinimumLength extends Validator{

I understand that merge can be used to combine enter and update selections in d3 v4, as in the simple example here: https://bl.ocks.org/mbostock/3808218 . I have a scatter plot in which multiple variables are displayed on a shared x-axis, for different groups selected by a dropdown box. When a new group is selected, the overall set of datapoints is updated, with points for each variable added like this: .each(function(d, i) { var min = d3.min(d.values, function(d) { return d.value; } ); var max = d3.max(d.values, function(d) { return d.value; } ); // Join new data with old elements var points

I have an MVC application that accesses SQL and Windows Azure. The logical flow looks like this: Person <--> View <--> Controller.ConvertPersonHere(x) <--> StorageContext.DoDataAction <--> AzurePersonTableEntity ConvertPersonHere is the answer to this Stack Overflow question and it converts the Model entity to the Storage entity public class Person { public string Name {get;set;} public int ID {get;set;} } public class PersonEntity : TableServiceEntity { public string Name {get;set;} public int ID {get;set;} // Code to set PartitionKey // Code to set RowKey } Now that I'm adding WCF to the mix
