Symfony 表单:如何更改表单生成的默认小部件 [英] Symfony forms: how to change default widget for form generation

问题描述

我正在为日期字段使用自定义小部件，并且我想在我的所有表单中使用它.问题是 symfony 使用默认的 sfWidgetFormDate.我想要的是更改此默认小部件，以便使用我的自定义小部件生成表单.我不想手动更改生成的所有表单.

I'm using a custom Widget for date fields, and I want to use it in all my forms. The problem is that symfony uses the default sfWidgetFormDate. What I want is to change this default widget in order to generate forms with my custom Widget. I don't want to change by hand all the forms generated.

我发现的唯一方法是修改 BaseFormDoctrine.php 的技巧:

The only approach I have found is the trik of modify BaseFormDoctrine.php:

public function setup()
{
    foreach($this->getWidgetSchema()->getFields() as $name=>$widget)
    {
        if($widget instanceof sfWidgetFormDate) 
        {
            $this->widgetSchema[$name] = new sfWidgetFormJQueryDate(array(
                'config' => '{}',
                'image'=>'/images/calendar.png',
            ));
        }
    }
}

推荐答案

您可以做的是创建自己的表单生成器类.

What you could do is create your own form generator class.

class myFormGenerator extends sfDoctrineGenerator
{

  public function getWidgetClassForColumn($column)
  { 
    switch ($column->getDoctrineType())
    {
      case 'date':
        return 'sfWidgetFormJQueryDate';
        break;
      default:
        return parent::getWidgetClassForColumn($column); 
    }
  }
}

将其保存在 lib 文件夹中的某个位置，清除缓存等.

Save that somewhere sensible in your lib folder, clearing the cache etc..

然后像这样重新运行你的 for 生成器......

Then rerun your for generator like so...

php doctrine:build-forms --generator-class='myFormGenerator'

我没有尝试过以上任何一种，但我认为这个理论是合理的......

I haven't tried any of the above, but the theory is sound I think...

查看以下文件，看看我是从哪里想到的:

Have a look at the following files to see where I figured this out from:

lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/task/sfDoctrineBuildFormsTask.class.php
lib/vendor/symfony/lib/plugins/sfDoctrinePlugin/lib/generator/sfDoctrineFormGenerator.class.php
