swift - Converting RealmSwift.List model object into structure -


the topic might not understable explain want achieve.

the exapmle json this:

  {      "name": "somename",      "addresses": [         {            "city": "berlin",            "street": "dunno"         },         {            "city": "paris",            "street": "dunno2"         }      ]   }

the realm objects :

public final class placeobject: object {     @objc dynamic var name = ""     var addresses = realmswift.list<address>()      override public static func primarykey() -> string? {         return "name" // it's wrong primary key, should id / auto incremenet id, example might this.     } }  public final class addressobject: object {     @objc dynamic var city = ""     @objc dynamic var street = ""      override public static func primarykey() -> string? {         return "city" // same above.     } }

and following amazing tutorial switching classes structrues using realm (protocols included there)

i've achived want except saving 1 object nested dictionaries / arrays.

the structures looks :

struct place {     public let name: string     public let addresses: [address] }  extension place : persistable {      public init(managedobject: managedobject) {         name = managedobject.name         addresses = managedobject.addresses     }      public func managedobject() -> placeobject {         let placeobj = placeobject()          placeobj.name = name         placeobj.addresses = addresses          return placeobj     }      public enum propertyvalue : propertyvaluetype {          case name(string)         case addresses([address])          public var propertyvaluepair: propertyvaluepair {             switch self {             case .name(let id):                 return ("name", id)             case .addresses(let id):                 return ("addresses", id)             }         }     }      public enum query: querytype {         case name(string)          public var predicate: nspredicate? {              switch self {             case .name(let value):                 return nspredicate(format: "name == %@", value)             }         }          public var sortdescriptors: [sortdescriptor] {             return [sortdescriptor(keypath: "name")]         }     } }  struct address {     public let city: string     public let street: string }  extension address : persistable {      public init(managedobject: managedobject) {         city = managedobject.city         address = managedobject.address     }      public func managedobject() -> addressobject {         let addreses = addressobject()          addreses.city = city         addreses.street = street          return addreses     }      public enum propertyvalue : propertyvaluetype {          case city(string)         case street(string)          public var propertyvaluepair: propertyvaluepair {             switch self {             case .city(let id):                 return ("city", id)             case .street(let id):                 return ("street", id)             }         }     }      public enum query: querytype {         case city(string)          public var predicate: nspredicate? {              switch self {             case .city(let value):                 return nspredicate(format: "city == %@", value)             }         }          public var sortdescriptors: [sortdescriptor] {             return [sortdescriptor(keypath: "city")]         }     } }

i expected errors:

error: cannot assign value of type 'list<addressobject>' type '[address]'         addresses = managedobject.addresses  error: cannot assign value of type '[address]' type 'list<addressobject>'         placeobj.addresses = addresses

my question how convert type [address] list<addressobject> , in different way match pattern ?

work around

there way in messy style. don't save nasted array inside placeobject create aditional key object , via key connect these 2 while retriving them data base. in opinion it's not nice way - redundant logic.

thanks in advance!

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
