Django：访问模板中的列表属性

I have a SQL query in a Django view and store the results in a variable. As far I know the result should be stored as a list.

我在Django视图中有一个SQL查询，并将结果存储在一个变量中。据我所知，结果应该存储为列表。

def assignments(request):

    cursor = connection.cursor()
    cursor.execute("SELECT o.article_id, o.amount, m.id, o.create_date, m.status FROM orders o, producers p, machines ma, matches m WHERE ma.producer_id=1 AND m.machine_id = ma.id AND m.order_id = o.id")
    articles = cursor.fetchall()

    context = {"article_list": articles}

    return render(request, 'assignments.html', context)

Then I want to transfer that data row by row in a table in my template.

然后我想在我的模板中的表中逐行传输该数据。

{% block body %}
<div class="container">
    <table class="table">
        <thead>...</thead>
            <tbody>
              {% for articles in article_list %}
                <tr>
                  <td>{{ articles.article_id }}</td>
                  <td>{{ articles.amount }}</td>
                  <td>{{ articles.id}}</td>
                  <td>{{ articles.create_date }}</td>
                  <td>{{ articles.status }}</td>
                </tr>
              {% endfor %}
            </tbody>
    </table>
</div>

{% endblock %}

Unfortunately the table is empty and is not showing any results. The query itself should be fine. I tested the query in my database workbench and it is showing the correct results.

不幸的是，该表是空的，没有显示任何结果。查询本身应该没问题。我在我的数据库工作台中测试了查询，它显示了正确的结果。

How can I access the data stored in variable articles from my template?

如何从模板中访问存储在变量文章中的数据？

PS: I'm far from being a programmer. So I don't really know any programming concepts/language.

Any help is highly appreciated. Thanks!

You have a list of lists. Each element in articles_list is just a list of values from the database; it does not have any knowledge of attributes like "id" or "amount".

你有一份清单清单。 articles_list中的每个元素只是数据库中的值列表;它不具备“id”或“amount”等属性的任何知识。

As Arpit says in the comments, you should be using Django models for this rather than raw SQL.

正如Arpit在评论中所说，你应该使用Django模型而不是原始SQL。
