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 %}
