for example have index action: def index if params[:query] @pharmaceutics = pharmaceutic.where("name ?", params[:query]) elsif params[:code] @pharmaceutics = pharmaceutic.where("barcode ?", params[:code]) else @pharmaceutics = pharmaceutic.all end end and when send 2 params: code , query filter pharmaceutics using both of them. have mysql database. i use scoped method, this: def index scope = pharmaceutic.scoped # pharmaceutic.all if use rails 4 scope = scope.where('name ?', params[:query]) if params[:query].present? scope = scope.where('barcode ?', params[:code]) if params[:code].present? @pharmaceutics = scope end you can write custom scopes , replace where(...) them make code clearer.

in exercice must replace object within loop. solution use "listiterator". colleague try use foreach syntax , play reference solution won't work. // doesn't work ( growable growable : growables ) { growable = growable.grow(); // return object (seed -> sprout, ..) } // (final listiterator<growable> = growables.listiterator(); it.hasnext();) { it.set(it.next().grow()); } from documentation[1], can read foreach not suitable replacement because don't have reference iterator. the program needs access iterator in order remove current element. for-each loop hides iterator, cannot call remove. therefore, for-each loop not usable filtering. not usable loops need replace elements in list or array traverse it. but have reference iterated object. wrong ? can explain me why "foreach" solution isn't working ? thanks [1] http://docs.oracle.com/javase/1.5.0/docs/guide/language/foreach.html in first snippet, take element gro...

following this answer, i'm trying replicate , iterate on customermodel properties. customermodel pippo = new customermodel(); type customer = pippo.gettype(); fieldinfo[] fields = customer.getfields(bindingflags.public | bindingflags.instance); when using debugger, fields has count = 0 customermodel has lot of public properties i'd see in fields. how can that? here's extract of properties declared i'd see. [datamember] public string id { get; set; } [datamember] public string loginname { get; set; } [datamember] public string password { get; set; } [datamember] public string creationdate { get; set; } perhaps binding flags incorrect? i'm new use of reflection. those properties, not fields. use getproperties instead of getfields . in c#: public class foo { // field: private string _name; // property: public string name { get; set; } // property: public string somethingelse { { ...

in other words, can fetchedresultscontroller return array of arrays? or array of nssets? code bellow example, of i'm trying do. possible? - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { //... nsset *objects = [_fetchedresultscontroller objectatindexpath:indexpath]; //... } the reason i'm doing this, is: if user swipes cell, , deletes it. need objects row deleted. , need display data on cell, calculation made on clocks day/row. here's core data model: each row must contain clock objects, given day, based on it's clockin property. clockin nsdate object. 1 row should represent 1 day. could figuring out predicate this? possible? also, i'm using sections in table view. these out of question. there 1 solution rather no go for, wich create year, month , day, entities. fix. seems odd need that, considering clockin property should give me need... thank you! you can accompl...
