How to sort own columns in admin panel with symfony?

Question

M schema.yml:

News:
  columns:
    title:
      type: string(50)
    category_id:
      type: integer(4)
  relations:
    Category:
      local: category_id
             


        

Answer 1

That is because you are trying to view a column named category_name and you don't have a getCategory_Name() method, the solution is very simple. Display the categoryname column not category_name.

config:
  actions: ~
  fields:  ~
  list:
    display: [news_id, title, categoryname]
    table_method: doSelectJoinCategory
  filter:
    display: [news_id, title, category_id]
  form:    ~
  edit:    ~
  new:     ~

public function getCategoryName()
{
  return $this->getCategories()->getCategoryName();
}

Answer 3

These are the steps to achieve the required result.

1. Define a table method in your generator.yml

   config:
     actions: ~
     fields:  ~
     list:
       display: [news_id, title, category_name]
       table_method: doSelectJoinCategory
   

2. 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');
     }
   }
   

3. 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]);
   }
   

4. 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’;
   }
   

5. 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 :

Change this line

<?php if ($field->isReal()): ?>

To this :

<?php if ($field->isReal() || $field->getConfig('sortBy')): ?>

Hope that helps you
