CakePHP的displayField用法 [英] CakePHP displayField usage

问题描述

你可以帮我如何使用CakePHP的displayField指令，我不知道如何使用它...

can you help me how to use CakePHP's displayField directive, I can not figure out how to use it...

所以，在模型文件中，我有以下代码...

so, in a model file, i have following code...

<?php

class Task extends AppModel {

class Task extends AppModel {

var $name = 'Task';
var $displayField = 'projectName';

//The Associations below have been created with all possible keys, those that are not needed can be removed
var $belongsTo = array(
    'User' => array(
        'className' => 'User',
        'foreignKey' => 'user_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''

如何使用它，在选择表单字段中显示fied projectName？

how can i use this, to display fied projectName in select form field?

!!

推荐答案

因此，您拥有 Task belongsTo Project （FK： project_id）。你想在任务/添加和任务/编辑视图中创建一个项目选择框。

So, you have Task belongsTo Project (FK: project_id). You want to make a project select box in tasks/add and tasks/edit views.

问题是项目表没有一个字段 name 或 title 所以选择框是空的，如果有一个 name 或 title 字段，对吗？

The problem is that the projects table doesn't have a field called name or title so the select box is empty. You wouldn't have any problems if there was a name or a title field, right?

解决方案，在项目模型中添加：

Well, here's the solution, in the Project model add this:

var $displayField = 'projectName';

所以你是在正确的方向，只是搞砸了模型有点。我希望你现在明白了吧;]

So you were going in the right direction, just messed up the models a bit. I hope you understand it now ;]
