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();
}
