Django template ifequal tag

I'm using an ifequal tag in my django template inside a loop where atleast one of the items should equal the other at some point in the loop but for some reason it never displays what it should. I was wondering if there are any weird cases that i should know about.

I have a list of int city ID's that should be checked as check boxes. so as i loop through all of the cities, for each one i loop through the ones that are supposed to be checked to see if the equal anywhere in the list. But for whatever reason none of them ever match. I verified that the data is right using the django shell, so i know its there, i think i'm missing some small detail with how i'm using it. Heres the code:

View:

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 开发者_运维问答= 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')

Template clip:

{% 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 %}

MemberProfile Model:

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

Console Test:

>>> 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]

Log Value:

1

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

Could it be that id is a string and city.id is an integer?

The code you've posted would go into infinite loops if either pflags or mflags were non-empty.

Consider e.g. this snippet from your code:

  i = 0
  while i < len(pflags):
   pflags[i] = int(pflags[i])

that's it -- end of loop -- no incrementing of i whatsoever. This is an infinite loop unless len(pflags) is 0!

Therefore, either you've posted code different from what you're using (in which case it's pretty peculiar for you to expect help;-), or both of those are indeed empty and therefore the inner loops in the template execute 0 times each.

I suspect the second possibility obtains, but of course I can't see those xxxFlags values to confirm my suspicion (you can, and should: log them, for Pete's sake!-).
