django一对多模型以及如何在前端实现详解

yipeiwu_com7年前 (2020-03-06)Python基础

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 %}
