實際錯誤對於參考： 屬性「category_id」或方法「getCategoryId（）」，「categoryId ）「，」isCategoryId（）「，」hasCategoryId（）「，」__get（）「存在並且在類」Pas \ ShopTestBundle \ Entity \ Product「中具有公共訪問權限。錯誤：既不是屬性......也沒有一種方法...存在並且具有公共訪問
我已經完成了我對這個錯誤的研究，但是我找不到它。爲什麼我能夠創造'產品'之前，但現在我不能？我看到getCategoryId方法不存在，但不應該有教條創建它們（因爲我確實與教條建立了關係）。
如果我添加屬性CATEGORY_ID我得到錯誤：
在執行時出現異常 'SELECT t0.id AS ID1，AS category_id2，t0.CategoryName AS CategoryName3 FROM類別T0 t0.category_id'：
SQLSTATE [42S22]：未找到列：1054'字段列表'中的未知列't0.category_id'
有人可以告訴我我做錯了什麼嗎？
關係是很多（產品）對一個（類別）。點擊添加新產品時發生錯誤。在此行中... ... <a class="btn btn-primary" href="{{ path('product_new') }}" role="button">Create a New Entry</a>導致這個...
{% extends '::base.html.twig' %}
{% block body -%}
<h1>Product creation</h1>
{{ form(form) }}
<ul class="record_actions">
<li>
<a href="{{ path('product') }}">
Back to the list
</a>
</li>
</ul>
{% endblock %}
