Python 在html表中模板化直接原始查询

Python 在html表中模板化直接原始查询,python,html,django,django-templates,Python,Html,Django,Django Templates,我是django的初学者,我使用的是只读数据库,我只想做一些选择,并在我的模板中将其显示为一个表,但我无法将coulmn按列返回到我的html表中,请帮助我, 我使用的是directky原始查询 Model.py 从django.db导入连接 # Create your models here. def dictfetchall(cursor): "Returns all rows from a cursor as a dict" desc = cursor.descriptio

我是django的初学者,我使用的是只读数据库,我只想做一些选择,并在我的模板中将其显示为一个表,但我无法将coulmn按列返回到我的html表中,请帮助我, 我使用的是directky原始查询

Model.py 从django.db导入连接

# Create your models here.
def dictfetchall(cursor):

    desc = cursor.description
    return [
        dict(zip([col[0] for col in desc], row))

{查询%中的实例为%}
{%为字段,值在instance.items%}
{{value}}
{%endfor%}
{%endfor%}
浏览器输出:

目前,您仅为每行输出一个
td

{% for instance in query %}
  {% for field, value in instance.items %}
    <tr>
      <td>{{ value }} </td>
    </tr>
  {% endfor %}
{% endfor %}
但是,您不能假定字典中键的顺序,因此您应该按键访问项目,或者重新考虑是否要使用
dictfetchall

{% for instance in query %}
    <tr>
      <td>{{ instance.EQUIP_ID }} </td>
      <td>{{ instance.LINE_ID }} </td>
      <td>{{ instance.PLANT_CODE }} </td>
      {% endfor %}
    </tr>
{% endfor %}
{%例如查询%中的实例]
{{instance.equipment_ID}
{{instance.LINE_ID}
{{instance.PLANT_CODE}
{%endfor%}
{%endfor%}

谢谢,这确实解决了我的问题,
{% for instance in query %}
    <tr>
      {% for field, value in instance.items %}
      <td>{{ value }} </td>
      {% endfor %}
    </tr>
{% endfor %}
{% for instance in query %}
    <tr>
      <td>{{ instance.EQUIP_ID }} </td>
      <td>{{ instance.LINE_ID }} </td>
      <td>{{ instance.PLANT_CODE }} </td>
      {% endfor %}
    </tr>
{% endfor %}
