为什么它不显示网络应用程序中每个测验的姓名、电子邮件、分数列表？

Question

在我的网络应用程序中，一旦管理员登录，它就会显示所有用户测验的所有结果。每列中都会显示每个测验的姓名、电子邮件和分数。但是当我尝试运行时，它只显示： 结果

名称 电子邮件 网络基础知识 网络工具和测试设备 网络电缆

并且没有数据显示

这是 models.py 中的表格：

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(150), unique=True)
    password = db.Column(db.String(150))
    first_name = db.Column(db.String(150))
    
    
    
class Course(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(100), nullable=False)

class Fundamentals_of_Networking_score(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    scores = db.Column(db.Integer)

class Network_Tools_and_Testing_Devices_score(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    scores = db.Column(db.Integer)

class Network_Cables_score(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    scores = db.Column(db.Integer)

这是 view.py 的片段：

@views.route("/showall", methods=["GET"])
def show_all():
    # Query all users along with their scores
    users_with_scores = db.session.query(User.first_name, User.email,
                                          Fundamentals_of_Networking_score.scores,
                                          Network_Tools_and_Testing_Devices_score.scores,
                                          Network_Cables_score.scores) \
        .join(Fundamentals_of_Networking_score, User.id == Fundamentals_of_Networking_score.id) \
        .join(Network_Tools_and_Testing_Devices_score, User.id == Network_Tools_and_Testing_Devices_score.id) \
        .join(Network_Cables_score, User.id == Network_Cables_score.id) \
        .all()

    # Convert the query result into a list of dictionaries
    scores_list = []
    for user_data in users_with_scores:
        scores_list.append({
            'first_name': user_data[0],
            'email': user_data[1],
            'Fundamentals_of_Networking_score': user_data[2],
            'Network_Tools_and_Testing_Devices_score': user_data[3],
            'Network_Cables_score': user_data[4]
        })

    print(scores_list)  # Add this line to check the content of scores_list

    return render_template("showall.html", scores_list=scores_list, user=None)

here the snippet of showall.html code 
<div class="card-header">
          <label style=" font-size: 1.5rem;">Results</label>
        </div>
        <table>
            <thead>
              <tr>
                <th>Name</th>
                <th>Email</th>
                <th>Fundamentals of Networking</th>
                <th>Network Tools and Testing Devices</th>
                <th>Network Cables</th>
              </tr>
            </thead>
            <tbody>
              {% for user_scores in scores_list %}
              <tr>
                <td>{{ user_scores.first_name }}</td>
                <td>{{ user_scores.email }}</td>
                <td>{{ user_scores.Fundamentals_of_Networking_score }}</td>
                <td>{{ user_scores.Network_Tools_and_Testing_Devices_score }}</td>
                <td>{{ user_scores.Network_Cables_score }}</td>
              </tr>
              {% endfor %}
            </tbody>
          </table>
          
      </div>

使用以下 html 更新您的 showall.html

<div class="card-header">
      <label style=" font-size: 1.5rem;">Results</label>
    <table>
        <thead>
          <tr>
            <th>Name</th>
            <th>Email</th>
            <th>Fundamentals of Networking</th>
            <th>Network Tools and Testing Devices</th>
            <th>Network Cables</th>
          </tr>
        </thead>
        <tbody>
          {% for user_scores in scores_list %}
          <tr>
            <td>{{ user_scores.first_name }}</td>
            <td>{{ user_scores.email }}</td>
            <td>{{ user_scores.Fundamentals_of_Networking_score }}</td>
            <td>{{ user_scores.Network_Tools_and_Testing_Devices_score }}</td>
            <td>{{ user_scores.Network_Cables_score }}</td>
          </tr>
          {% endfor %}
        </tbody>
      </table>
      
  </div>
