django一对多模型以及如何在前端实现详解

models.py

class xm(models.Model):
xmID=models.AutoField(primary_key=True)
xmTitle=models.CharField('项目标题',max_length=50)
xmDate=models.DateField('时间',auto_now_add=True)

class Meta:
db_table="std_web_xm"
verbose_name="项目概况"
verbose_name_plural=verbose_name

def __unicode__(self):
return self.title
def __str__(self):
#强制转换为int类型
return str(self.xmID)#为了使在xadmin中成功显示为xmID

class xmProgress(models.Model):
xmProgress_ID=models.AutoField(primary_key=True)
xmProgress = models.CharField('项目进展', max_length=50, blank=True)
xmDesc = models.CharField('详情', max_length=50, blank=True)
#关联主键xmID ，级联删除
cid=models.ForeignKey("xm",on_delete=models.CASCADE)
xmProgress_Date=models.DateField('更新时间',auto_now_add=True)
class Meta:
db_table="std_web_xmProgress"
verbose_name="项目详情"
verbose_name_plural=verbose_name

def __unicode__(self):
return self.title

注册到adminx.py中

class XmAdmin(object):
list_display = ['xmTitle','xmDate']
#style_fields = {"xmContent": "ueditor"}

class XmProgressAdmin(object):
list_display=['cid','xmProgress','xmProgress_Date','xmDesc']

xadmin.site.register(xm,XmAdmin)
xadmin.site.register(xmProgress,XmProgressAdmin)

views.py

def xm_detail(request,xmID):
xm_detail=xm.objects.get(pk=xmID)
xmProgress_detail=xmProgress.objects.filter(cid=xm_detail)
return render(request,'xmgk/xmgk_detail.html',{'xmProgress_detail':xmProgress_detail,'xm_detail':xm_detail})

前端代码

{% for line in xmProgress_detail %}
<tr>
<td>{{ line.xmProgress_Date|date:"Y-m-d" }}</td>
<td>{{ line.xmProgress }}</td>
<td>{{ line.xmDesc }}</td>
</tr>

{% endfor %}
