问题 I have a database and model called Vote_actions that looks like this: id group_id user_id action_type anonymous (boolean) User can ask to be anonymous (that would make the boolean value to be true).If that is the case, I want to change the group_id and user_id from the returned model to -1. Is there a way in laravel that I can do it ? 回答1: You are leaning towards an edge case, with special conditions. Make use of accessors: class VoteActions extends \Eloquent { public $casts = [ 'anonymous' =

Hi I have created a mutator to only store digits on my phone numbers. Here is my code in my Profile Model. public function setPhoneAttribute($phone) { $this->attributes['phone'] = preg_replace("/[^0-9]/","",$phone); } This works when I create a new record, but if I update the record it does not work. My question is how do I execute the Mutator on both create and update? Here is how I update and create in my controller: namespace App\Http\Controllers; use App\Http\Requests; use App\Http\Requests\ProfileRequest; use App\Http\Controllers\Controller; use Illuminate\Http\Request; use Auth; use App

问题 Sometimes I need to expose some of the class members. For example in the following example class Mechanic may need direct access to Engine component. I have read many times that all fields should be accessed by mutator (accessor) methods because of several reasons. But is there any advantage when providing non-const reference getter: class Car { public: Engine & engine() { return m_engine; } //as a consequence you will also need to provide const version const Engine & engine() const { return

I am working on a homework assignment. I am confused on how it should be done. The question is: Create a class called IDCard that contains a person's name, ID number, and the name of a file containing the person's photogrpah. Write accessor and mutator methods for each of these fields. Add the following two overloaded constructors to the class: public IDCard() public IDCard(String n, int ID, String filename) Test your program by creating different ojbects using these two constructors and printing out their values on the console using the accessor and mutator methods. I have re-written this so

How can I fix/get around it? 回答1: list.append is a method that modifies the existing list. It doesn
