Question

在我的rider_detail.html中，我应该能够看到带有骑手得分的表格，但我看不到

我的模型。py：

class Rider(models.Model):
    id_rider = models.IntegerField(default = 0,blank= True, primary_key=True)
    [...]

    def __str__(self):
        return self.display_name

class Risultato(models.Model):
    TYPE_CHOICES = (('SR','sr'),('ITT', 'itt'),('HC', 'hc'),('1C','1c'),('TTT','ttt'))
    id_ris = models.IntegerField(default = 0,blank= True, primary_key=True)
    id_rider = models.ForeignKey(Rider,related_name='rider', on_delete=models.CASCADE)
    id_stage = models.ForeignKey(Stage,related_name='team', on_delete=models.CASCADE)
    type_ris = models.CharField(choices=TYPE_CHOICES,max_length = 256,blank= True)
    rank = models.IntegerField(default = 0,blank= True)
    punti = models.IntegerField(default = 0,blank= True)

    def __str__(self):
        return str(self.id_ris)

我的view.py：

class RiderDetails(DetailView):

    model = Rider
    template_name = 'game/rider_detail.html'

    def get_context_data(self, *args, **kwargs):
        context_data = super().get_context_data(**kwargs)
        context_data['risultato_qs'] = Risultato.objects.filter(id_rider=self.object)
        return context_data

我的rider_detail.html

{% extends 'game/base.html'%}
{% block content %}
<h1>{{ rider.display_name }}</h1>
<p>
    <h3>age:</h3>{{rider.age}}
    <h3>nationality:</h3>{{rider.nationality}}
    <h3>height:</h3>{{rider.height}} 
    <h3>weight:</h3>{{rider.weight}}
    <h3>team:</h3>{{rider.team}} 
</p>
<h3></h3>

<h2>          Score history</h2>
<table>
    <tbody>
    {% for risultato in risultato_qs %}
        <tr>
            {{ risultato }}
            <td>{{ risutato.type_ris }}</td>
            <td>{{ risutato.punti }}</td>
            ... etc ...
        </tr>
    {% endfor %}
    </tbody>
</table>
{% endblock %}

我已经安装了Django Debug Toolbar，以查看查询是否正确。实际上，我们看到2个结果，一个结果为100分（“蓬蒂”），另一个结果为50分。

Answer 1

在for循环中，您使用的是risutato而不是risultato。更改为：

{% for risultato in risultato_qs %}
  <tr>
    <td>{{ risultato.type_ris }}</td>
    <td>{{ risultato.punti }}</td>
  </tr>
{% endfor %}

Answer 2

您的循环中有错别字。您可以将loop更改为此：

rider_detail.html

{% for risutato in risultato_qs %}
    <tr>
        {{ risutato }}
        <td>{{ risutato.type_ris }}</td>
        <td>{{ risutato.punti }}</td>
        ... etc ...
    </tr>
{% endfor %}

或者按照Alasdair中指定的相反方法。

我看不到模板中的所有数据
