我正在调试Django项目，并希望在网页的表格中显示数据库中的另一个字段。
当前在网页中显示的表格的Django HTML是：
<table class="multisection pipeline left">
<tr class="sub-summary">
<th colspan="4"><a href="?detailed_status={{detailed_status}}"><h3 class="p-l-sm">{{detailed_status_str}}</h3></a></th>
{% if total_i %}<th>Initial exc VAT: {{total_i|money:"£"}}</th>{% endif %}
{% if total_u %}<th>Latest exc VAT: {{total_u|money:"£"}}</th>{% else %}
<th></th>
{% endif %}
</tr>
</table>
<table class="multisection pipeline left m-b-xl">
<tr class="summary">
<th style="width: 3em;"></th>
{% for field in fields %}
<th class="text-sm p-l-sm p-t-sm p-b-sm" style="width:{{widths|getval:forloop.counter0}}">
{% if field.1 %}
{% if sort == field.0 and not reverse %}
<a href="?sort=-{{field.0}}&detailed_status={{detailed_status}}">{{field.0}}</a>
{% else %}
<a href="?sort={{field.0}}&detailed_status={{detailed_status}}">{{field.0}}</a>
{% endif %}
{% else %}
{{field.0}}
{% endif %}
</th>
{# Make all have the same number of columns (8) #}
{% if forloop.last %}
{% for i in ',,,,,,,,' %}
{% if forloop.counter|add:forloop.parentloop.counter0 < 11 %}
<th> </th>
{% endif %}
{% endfor %}
{% if detailed_status == "ds4"|ds %}
<th></th>
{% endif %}
{% endif %}
{% endfor %}
</tr>
{% with user.employee.full_name|is:'Nick Ross' as summary_link %}
{% for project in projects %}
<tr data-project-id="{{project.id}}" class="{% cycle 'odd' 'even' %}{% if project.office == 2 %} col{% endif %}">

，目前显示的是包含以下列标题的表格：
项目名称，城镇，邮政编码，联系人姓名
这些列标题是属于类Project的字段，它在models.py文件中定义：
class Project(models.Model):
...
ds2 = 20
...
ds9 = 120
...
ds13 = 200
DETAILED_STATUS_CHOICES = (
...
ds9, 'Live project'),
...
)
# Several form fields added here, e.g.
employees = models.ManyToManyField(Employee, through=ProjectEmployee)
client = models.ForeignKey(Client, on_delete=models.SET_NULL, null=True, blank=True)
# Several 'def's here, e.g.
def team(self):
employees = self.assigned.all()
...
sm = [person for person in employees if person.role==Role.SM]
...
return{
...
'Site manager': sm[0].employee.first_name if sm else '',
...
}
# Several `@property` definitions here, e.g.
@property
def estimated_compeltion(self):
...
我想在网页上的表格中显示数据库中的Site manager字段 - 我尝试将其添加到Python代码中，如上所示，但这对于什么没有影响显示在网页上，即使它看起来与显示数据库中所有其他字段的方式完全相同。
我在这里缺少什么？我希望Django HTML能够在Python代码中显示我告诉它的每个字段，因为我使用forloop来获取字段...为什么我看不到'Site我已经添加到HTML网页表格中的代码的经理字段了吗？
答案 0 :(得分：0)
使用<td/>
project.site_manager
虽然您的Project模型似乎没有这样的字段，但这就是为什么没有显示的原因。
也许您可以在project_manager类中为Project创建一个getter，如下所示：
def get_site_manager(self):
sm = [person for person in self.assigned.all() if person.role==Role.SM]
return sm[0].employee.first_name if sm else ''
并在模板中使用它：
<td>{{project.get_site_manager()}}</td>
