model_class: News

list:
display: [news_id, title, category_name]
filter:
display: [news_id, title, category_id]
form: ~
edit: ~
new: ~
在 news.class 中:
In news.class:
public function getCategoryName()
{
return $this->getCategories()->getCategoryName();
}
这可行，但我无法对该字段进行排序.我可以按 id、title、category_id 排序，但不能按 category_name 排序.如何按此自定义列排序?
This works, but I can't sort this field. I can sort by id, title, category_id, but not by category_name. How can I sort by this custom column?
推荐答案
这些是达到所需结果的步骤.
These are the steps to achieve the required result.
在你的 generator.yml 中定义一个表格方法
Define a table method in your generator.yml
config:
actions: ~
fields: ~
list:
display: [news_id, title, category_name]
table_method: doSelectJoinCategory
将 doSelectJoinCateory 添加到您的 NewsTable.class.php
Add doSelectJoinCateory to your NewsTable.class.php
class NewsTable extends Doctrine_Table
{
...
public static function doSelectJoinCategory($query)
{
return $query->select('r.*, c.cateogry_name')
->leftJoin('r.Category c');
}
}
你需要覆盖你的actions.class.php中的排序查询
You need to override the sort query in your actions.class.php
class newsActions extends autoNewsActions
{
...
protected function addSortQuery($query)
{
if (array(null, null) == ($sort = $this->getSort()))
{
return;
}
if (!in_array(strtolower($sort[1]), array('asc', 'desc')))
{
$sort[1] = 'asc';
}
switch ($sort[0]) {
case 'category_name':
$sort[0] = 'c.category_name';
break;
}
$query->addOrderBy($sort[0] . ' ' . $sort[1]);
}
默认生成器主题将要求您覆盖 actions.class.php 中的 isValidSortColumn
The default generator theme will require that you override the isValidSortColumn in actions.class.php
protected function isValidSortColumn($column)
{
return Doctrine_Core::getTable(‘Payment’)->hasColumn($column) || $column == ‘cateogry_name’;
}
您需要覆盖生成器主题以显示排序链接和图标，因为它要求排序字段是真正的数据库映射字段.编辑你的 symfony_dir/lib/plugins/sfDoctrinePlugin/data/generator/sfDoctrineModule/admin/template/templates/_list_th_tabular.php :
You will need to override the generator theme to display sort link and icons as it requires the sort field to be real database mapped field. edit your symfony_dir/lib/plugins/sfDoctrinePlugin/data/generator/sfDoctrineModule/admin/template/templates/_list_th_tabular.php :
改变这一行
<?php if ($field->isReal()): ?>
对此:
<?php if ($field->isReal() || $field->getConfig('sortBy')): ?>
