i've seen scala code snippet somewhere: def tosentiment(sentiment: int): sentiment = sentiment match { case x if x == 0 || x == 1 => sentiment.negative case 2 => sentiment.neutral case x if x == 3 || x == 4 => sentiment.positive } is there way rewrite case statement more concisely? suspect there must simpler (shorter) way express x if x == 0 || x == 1 condition. by way, form: def tosentiment(sentiment: int): sentiment = sentiment match { case 0 => sentiment.negative case 1 => sentiment.negative case 2 => sentiment.neutral case 3 => sentiment.positive case 4 => sentiment.positive } is not i'm looking for. i'm hoping this: def tosentiment(sentiment: int): sentiment = sentiment match { case x in {0, 1} => sentiment.negative case 2 => sentiment.neutral case x in {3, 4} => sentiment.positive } or even: def tosentiment(sentiment: int): sentiment = sentiment match { case 0, 1 =&g

within site, use variable $location keeps track of page user viewing. @ end of index.php, variable copied $_session array, upon next request know user last time (i use generating "back" links). index.php goes this: $location = getlocation(); // gets user location processing $_post , $_get if(!isset($_session['last_location'])) $_session['last_location'] = somemeaningfullocation(); . . outputpage(); // renders page based on $location . . $_session['last_location'] = $location; so in outputpage(), $_session['last_location'] variable can used generating "back" links. problem is: this code works msie, chrome , safari . doesn't, however, work firefox nor seamonkey (which use web development). in these browsers, "back" links point frontpage . other facts might useful: session data stored in files, server date , time set right i've tried playing cache settings ( header('cache-co

ruby on rails - HAML: tr[@user] translates to class and ID, but how? -

-
as know, haml translates tr[@user] <tr class="user" id="user_123">... . how achieve this? through internal magic? or using functionality of @user object? what want achieve following. have contact model company , person subclass. when using tr[@company] , i'd haml following: <tr class="contact company" id="company_123"> ...instead of only: <tr class="company" id="company_123"> is there easy way achieve this? thank you. you can implement haml_object_ref method in model override haml uses value of class attribute. if use direct subclasses of contact simple should work in contact model: def haml_object_ref "#{self.class.superclass.to_s.underscore} #{self.class.to_s.underscore}" end (this uses activesupport underscore method.) if want use contact instances directly, or subclasses of person or company , this: def haml_object_ref classes = [] klass =

javascript - Angular Schema Form - Array validation -

-
i trying make array of unique values using schema form seems impossible task. to keep things simple lets consider simple unique validator: $scope.validateunique = function(value) { console.log('running validation'); var samename = $scope.model.noduplicate.filter(function(item) { return item.key === value; }); return samename.length < 2; } open console , visit fiddle . step 1: add new item called 1. step 2: add new item called 12. step 3: add new item called 123. step 4: add new item called 1234. so far good. step 5: change first item (1) 1234 error message appears. step 6: delete last item first 1 unique again. nothing happens. array not validated again once item removed , if click on submit button should trigger valdiation of form nothing happens. is issue mistake? there mistake in example code? or sort of schema-form bug? how achieve revalidation of array either on removing of item or submitting form? thanks! solve
