Python 在html表格中显示django模型的一部分

如何在HTML模板中仅显示Django模型的某些列？ 还有：如何对其中一个记录执行函数？（金额）？ 现在我正在显示一整张模型表，如下所示：

my

models.py

class Tabela(models.Model):
block_id = models.CharField(max_length=64)
timestamp = models.DateTimeField()
type =  models.CharField(max_length=32)
link =  models.CharField(max_length=64)
link_as_account =  models.CharField(max_length=100)
account =  models.CharField(max_length=100)
amount =  models.CharField(max_length=64)

def __str__(self):
    return self.block_id

def search_results(request):
model = Tabela
query_addresse = request.GET.get('addressee', None)
query_hash = request.GET.get('hash', None)

if not query_hash and not query_addresse and request.method == 'GET':
    return render(request, 'nanosite/index.html', {})

if query_hash and request.method == 'GET':
    if query_addresse:
        result = Tabela.objects.filter(account=query_addresse, block_id=query_hash)
    else:
        result = Tabela.objects.filter(block_id=query_hash)
    field_names = [f.name for f in model._meta.get_fields()]
    data = [[getattr(ins, name) for name in field_names]
            for ins in result]

elif query_addresse and request.method == 'GET':
    result = Tabela.objects.filter(account=query_addresse)
    field_names = [f.name for f in model._meta.get_fields()]
    data = [[getattr(ins, name) for name in field_names]
            for ins in result]
return render(request, 'nanosite/index.html', {'field_names': field_names, 'data': data})

我的

视图.py

class Tabela(models.Model):
block_id = models.CharField(max_length=64)
timestamp = models.DateTimeField()
type =  models.CharField(max_length=32)
link =  models.CharField(max_length=64)
link_as_account =  models.CharField(max_length=100)
account =  models.CharField(max_length=100)
amount =  models.CharField(max_length=64)

def __str__(self):
    return self.block_id

def search_results(request):
model = Tabela
query_addresse = request.GET.get('addressee', None)
query_hash = request.GET.get('hash', None)

if not query_hash and not query_addresse and request.method == 'GET':
    return render(request, 'nanosite/index.html', {})

if query_hash and request.method == 'GET':
    if query_addresse:
        result = Tabela.objects.filter(account=query_addresse, block_id=query_hash)
    else:
        result = Tabela.objects.filter(block_id=query_hash)
    field_names = [f.name for f in model._meta.get_fields()]
    data = [[getattr(ins, name) for name in field_names]
            for ins in result]

elif query_addresse and request.method == 'GET':
    result = Tabela.objects.filter(account=query_addresse)
    field_names = [f.name for f in model._meta.get_fields()]
    data = [[getattr(ins, name) for name in field_names]
            for ins in result]
return render(request, 'nanosite/index.html', {'field_names': field_names, 'data': data})

我的

index.html

        <div id="bottomhalf" class="table-responsive">
        <table class="table table-sm table-dark table-hover">
            <thead class="thead-light">
                {% for head in field_names %}
                   <th scope="col">{{ head }}</th>
                {% endfor %}
            </thead>
            <tbody>
                {% for row in data %}
                    <tr scope="row">
                        {% for cell in row %}
                            <td>{{ cell }}</td>
                        {% endfor %}
                    </tr>
                {% endfor %}
            </tbody>
        </table>
    </div>

{字段_names%}中的头为%
{{head}}
{%endfor%}
{数据%中的行为%1}
{第%行中的单元格为%1}
{{cell}}
{%endfor%}
{%endfor%}

我想做的是在html中只显示

块id

，

时间戳

，

帐户

和

金额

。我尝试过不同的方法，比如只使用视图的结果部分，而不使用字段名和数据，但当然不起作用

我的另一个问题是，如何修改字段

amount

，并对其执行一个操作，使其显示在模板中，如amound除以某个数字，前面有一个$符号（例如，如果amount=1488除以124，显示为“$12”）？

将选择要显示的对象的查询集

qs

传递到模板，并在其上迭代以生成表格：

{% for obj in qs %}
    <tr>
        <td> {{obj.block_id}} </td>
        <!-- etc ... -->
    </tr>
{% endfor %} 

然后可以在模板中运行内部循环

<tr>
{% for name in selected_field_names %}
   <td> {{obj|attr:name}} </td>
{% endfor %}
</tr>

并参考模板中的

{{obj.fully\u amount}

<tr>
{% for name in selected_field_names %}
   <td> {{obj|attr:name}} </td>
{% endfor %}
</tr>
