我在views.py中定义了两个函数来获取第一个带有特定elementimenu的prova.html ,然后,在单击其中一个之后,我再次获得了与具有相同id的elementimenu关联的elementimenu和elementi的页面,即:
another_app.model.py
...
class ElementiTab(models.Model):
author = models.ForeignKey('auth.User', null=True, blank=False)
des = models.CharField(max_length=30)
x = models.FloatField()
y = models.FloatField()
res = models.FloatField(default=0)
created_date = models.DateTimeField(default=timezone.now)
...
这里是我希望变得更好的代码:
视图.py
from another_app.model import ElementiTab
def show_elementi(request):
elementimenu = ElementiTab.objects.all()
return render_to_response('homepage/prova.html',{'elementimenu': elementimenu, 'user.username': request}, context_instance = RequestContext(request))
def show_detail(request,id):
elementimenu = ElementiTab.objects.all()
detail = get_object_or_404(ElementiTab, pk=id)
return render_to_response('homepage/prova.html',{'elementimenu': elementimenu, 'detail': detail, 'user.username': request}, context_instance = RequestContext(request))
网址.py
...
url(r'^homepage/prova/$', views.show_elementi),
url(r'^show_detail/(?P<id>\d+)/$', views.show_detail),
...
prova.html
...
<div class="elementi">
{% for elementi in elementimenu %}
<a href="/show_detail/{{elementi.id}}">{{elementi.des}}</a>
{% endfor %}
</div>
<div class="table-responsive">
<table class="table table-bordered">
<tr class="info">
<td width="35%" align="center"> NOME</td>
<td width="35%" align="center"> DATA CREAZIONE </td>
<td width="30%" align="center"> AUTORE </td>
</tr>
{% if detail %}
<div class="dettagli">
<tr>
<td>{{detail.des}}</td>
<td>{{detail.created_date}}</td>
<td>{{detail.author}}</td>
</tr>
{% endif %}
</div>
</table>
</div>
...
我在show_detail视图中使用了这个“技巧”,这样即使在调用这个函数之后我也可以看到elementimenu 。
有没有更优雅的方法来做到这一点?
