python - Django 模板 ifequal 标签

Question

我在循环中的 django 模板中使用 ifequal 标记，其中至少一个项目在循环中的某个点应等于另一个项目，但由于某种原因它从不显示它应该显示的内容。我想知道是否有任何我应该知道的奇怪案例。

我有一个 int 城市 ID 列表，应该将其作为复选框选中。因此，当我遍历所有城市时，对于每个城市，我都会遍历应该检查的城市，以查看列表中的任何地方是否相等。但无论出于何种原因，它们都不匹配。我使用 django shell 验证了数据是正确的，所以我知道它在那里，我想我遗漏了一些关于我如何使用它的小细节。继承人的代码:

查看:

def editprof(request):
    try:
        if request.session['id']:
            loggedin = True
    except KeyError:
        loggedin = False
    try:
        citylist = CityList.objects.all()
        userid = request.session['id']
        user = MemberProfile.objects.get(pk=userid)
        p = decrypt_pwd(user.Password)
        pflags = user.PublicVisibleFlags
        log_val(pflags[0])
        pflags = pflags.split(',')
        mflags = user.MemberVisibleFlags
        log_val(mflags[0])
        mflags = mflags.split(',')
        return render_to_response('editprof.html', {'user':user, 'p':p, 'loggedin':loggedin, 'citylist':citylist, 'pflags':pflags, 'mflags':mflags})
    except KeyError:
        return HttpResponse('You must be logged in to view this page!')
    except MemberProfile.DoesNotExist:
        return HttpResponse('DatabaseError')

模板剪辑:

{% for city in citylist %}
 <tr>
  <td><input type='checkbox' name='public' value='{{ city.id }}' {% for id in pflags %}{% ifequal id city.id %}checked{% endifequal %}{% endfor %} /></td>
  <td><input type='checkbox' name='private' value='{{ city.id }}' {% for id in mflags %}{% ifequal id city.id %}checked{% endifequal %}{% endfor %} /></td>
  <td>{{ city.CityName }}</td>
 </tr>
{% endfor %}

成员(member)资料模型:

class MemberProfile(models.Model):
    Username = models.CharField(max_length=12,unique=True)
    Password = models.CharField(max_length=12)
    SecurityLevel = models.IntegerField()
    AccountExpirationDate = models.DateField()
    CityList = models.TextField()
    Address1 = models.CharField(max_length=30)
    Address2 = models.CharField(max_length=30)
    City = models.CharField(max_length=20)
    State = models.CharField(max_length=2)
    Zip = models.CharField(max_length=10)
    Email = models.EmailField()
    AltEmail = models.EmailField()
    HomePhone = models.CharField(max_length=18)
    BusinessPhone = models.CharField(max_length=18)
    Fax = models.CharField(max_length=18)
    Cell = models.CharField(max_length=18)
    AltPhone = models.CharField(max_length=18)
    PublicVisibleFlags = models.TextField()
    MemberVisibleFlags = models.TextField()
    WhoAmI = models.TextField()
    CompanyName = models.CharField(max_length=30)
    ServicesOffered = models.TextField()
    NumberOfUnits = models.IntegerField()
    SCREIAOffice = models.CharField(max_length=10)
    LastModifyBy = models.CharField(max_length=12)
    LastModifyDate = models.DateField(auto_now=True)

    def __unicode__(self):
        return self.Username

控制台测试:

>>> from screia.core.models import MemberProfile
>>> user = MemberProfile.objects.get(pk=1)
>>> pflags = user.PublicVisibleFlags.split(',')
>>> print pflags
[u'1', u'4', u'7', u'12', u'25']
>>> i = 0
>>> while i < len(pflags):
...   pflags[i] = int(pflags[i])
...   i+=1
... 
>>> print pflags
[1, 4, 7, 12, 25]

Answer 1

{% for id in pflags %}{% ifequal id city.id %} ... {% endfor %}

难道id是字符串，city.id是整数？
