model

问题 I'm stuck for few days with this error, and I don't know how to solve it. I have 2 models in my app : User and Team . user.ts : import { Team } from './team'; export class User { id: string = null; name: string = null; email: string = null; settings: any = {}; team: Team = null; constructor(json?: Object){ var defaultSettings = {}; if(json){ this.id = json['id'] || null; this.name = json['name'] || null; this.email = json['email'] || null; this.settings = json['settings'] || {}; this.team =

问题 In our application we've overridden the ActiveRecord destroy method so that our records do not get deleted (so the user can undelete). Like so: def destroy self.is_deleted = true self.save freeze end However, this seems to have disabled the dependent destroy on our has_many relationships. In other words, if destroy is called on a parent object, the child objects of has_many do not get destroyed (they don't get deleted, i.e, SQL ' DELETE... ', nor is the overridden destroy -method called). How

问题 Fairly simple question, but I can't seem to find anything about it. I've got a set of ids, and I need to find all matching records. So I'd like to query : $records = MyModel::findIn([1,2,3,4]); But I don't know how to implement it. Any idea ? 回答1: Check out the Phalcon\Mvc\Model\Criteria, in the inWhere method. You could create a new model's method like: public static function findIn(array $identifiers) { return self::query() ->inWhere('id', $identifiers) ->execute(); } 来源： https:/

问题 I have a model called Category which looks like this: class Category < ActiveRecord::Base has_many :categories belongs_to :category,:foreign_key => "parent_id" end I have a view which shows all the categories with some of their attributes. I can access category.parent_id , but I would like to be able to do something like category.parent_name . I can see myself creating a model method to fetch all categories and filling the collection with the correspondent parent name of each category, but I

问题 I have a model for one of my database tables. I want to override the column name for that particular table. How would I achieve it. For example, let my table be called DUMMY and it has one column called col_a col_a 20 34 42 23 12 I would be doing a @dummy.col_a . Now this method should return me 0 for numbers ending with 0 and for everything else, it should return the original value. I could do that by defining a new method, but I want to override the column name itself. Please help. 回答1: You

问题 I have a Model within Laravel called Blah (I named it this way because you can't simply name a class Class , so I changed the name temporarily).

问题 I want two of my models to inherit a property and a couple of methods. I know I could put the methods in a behaviour but I'm not sure about the property. Can a behaviour have variables that are inherited by the model? Or should I just create another model that extends AppModel, and have the two models extend that one? 回答1: As long as both methods and variables are made public you can put your code into a behavior. In general I would go for a behavior, I guess. You could then create some
