Эй, я просмотрел несколько похожих сообщений на SO, но не нашел ничего, что решило бы мою проблему.У меня есть следующие модели,
from django.db import models
class Areas(models.Model):
name = models.CharField(max_length = 120)
order_in_sidebar_network = models.IntegerField(blank=True, null=True)
order_in_section_network = models.IntegerField(blank=True, null=True)
def __unicode__ (self):
return self.area_name
class Meta:
verbose_name_plural = "Areas"
verbose_name = "Area"
class Countries(models.Model):
name = models.CharField(max_length = 120, help_text = "The name of the country")
area = models.ForeignKey(Areas, verbose_name = 'Area')
def __unicode__ (self):
return self.name
class Meta:
verbose_name_plural = "Countries"
verbose_name = "Country"
ordering = ['name']
class Offices(models.Model):
country = models.ForeignKey(Countries, verbose_name = 'Country')
name = models.CharField(max_length = 255, help_text = "The name of this office, IE London")
main_office = models.BooleanField(default= False, help_text = "Is this office a key location?", verbose_name = "Key Location")
address_1 = models.CharField(max_length = 255, null = True, blank = True)
address_2 = models.CharField(max_length = 255, null = True, blank = True)
address_3 = models.CharField(max_length = 255, null = True, blank = True)
city = models.CharField(max_length = 255, null = True, blank = True)
postcode = models.CharField(max_length = 20)

data_1 = models.CharField(max_length = 255, null = True, blank = True, help_text = "Optional additional data", verbose_name = "Additional information")
data_2 = models.CharField(max_length = 255, null = True, blank = True, help_text = "Optional additional data", verbose_name = "Additional information")
class Meta:
verbose_name_plural = "Offices"
verbose_name = "Office"
ordering = ['name']
def __unicode__(self):
return self.name
class OfficeMembers(models.Model):
name = models.CharField(max_length = 60, help_text = "Please tell us this person name")
title = models.CharField(max_length = 100, help_text = "The person's title, IE Managing Director")
email = models.EmailField(max_length = 255, null = True, blank = True, help_text = "Optional email address for this person")
email2 = models.EmailField(max_length = 255, null = True, blank = True, help_text = "Optional second email address for this person")
phone = models.CharField(max_length = 30, null = True, blank = True, help_text = "Optional contact number for this person")
mobile = models.CharField(max_length = 30, null = True, blank = True, help_text = "Optional mobile contact number for this person")
office = models.ForeignKey(Offices, null = True)
class Meta:
verbose_name_plural = "Office Memebers"
verbose_name = "Office memebr"
ordering = ['name']
def __unicode__(self):
return self.name
У меня есть следующее настроенное представление
def index(request):
cache_key = "world_areas"
cache_time = 60
world_areas_cache = cache.get(cache_key)
#if no cache is set, grab the objects, and set the cache
logger.debug(world_areas)
if not world_areas_cache:
logger.info('No cache found grabbing objects')
world_areas = Areas.objects.select_related().all()
#cache.set(cache_key, world_areas, cache_time)
logger.debug(world_areas)
else:
logger.info("Getting from cache")
world_areas = world_areas_cache
return render_to_response('network/index.html', {'world_areas':world_areas}, context_instance=RequestContext(request))
, пытающееся перебрать объект world_areas, как это производитсинтаксическая ошибка шаблона
Объект «RelatedManager» не повторяется
У кого-нибудь есть идеи, почему это происходит?действительно не могу обойти это!странно, это работает для меня в оболочке: S я пропускаю что-то очевидное ???
Большое спасибо всем, кто может помочь!
