Django中的单个视图/模板上的多个模型

from django.shortcuts import render
from .models import Model1, Model2

def my_view(request):
    model1_data = Model1.objects.all()
    model2_data = Model2.objects.all()
    context = {
        'model1_data': model1_data,
        'model2_data': model2_data
    }
    return render(request, 'my_template.html', context)

{% for item in model1_data %}
    <!-- 渲染model1的数据 -->
{% endfor %}

{% for item in model2_data %}
    <!-- 渲染model2的数据 -->
{% endfor %}

from django.shortcuts import render
from .models import Model1

def my_view(request):
    model1_data = Model1.objects.all()
    context = {
        'model1_data': model1_data
    }
    return render(request, 'my_template.html', context)

{% for item in model1_data %}
    <!-- 渲染model1的数据 -->
    {% for related_item in item.model2_set.all %}
        <!-- 渲染model2的数据 -->
    {% endfor %}
{% endfor %}

from django.shortcuts import render
from .models import Model1, Model2

def my_view(request):
    custom_query = Model1.objects.raw('SELECT * FROM myapp_model1, myapp_model2 WHERE ...')
    context = {
        'custom_query': custom_query
    }
    return render(request, 'my_template.html', context)

{% for item in custom_query %}
    <!-- 渲染自定义查询的结果 -->
{% endfor %}
