Django URL 配置
假设我有 3 个模型:城市、区域、条目。
每个城市都有多个区域,每个区域可以有多个条目,但对于“现在”来说,只能有一个活动条目并且它将被显示。所以在逻辑上:
请注意,每个城市、区域、条目将使用相关模型类的 slug 变量
格式将如下:
www.mysite.com/<slug of city>/<slug of area>/<slug of entry>
www.mysite.com/mycity/myarea/
->将显示绑定到该区域并且处于活动状态的条目(这可以通过使用区域的 active_entry
函数来检测)。
但用户可以查看一些旧条目,例如:
www.mysite.com/mycity/myarea/some-old-entry-that-is-no-longer-active
我已经通过阅读编写了 get_absolute_url 函数“实用 Django 项目第二版”书,但现在我陷入困境。
我有这样的模型:
from django.db import models
class Entry(models.Model):
area = models.ForeignKey('Area',verbose_name="The area that this entry belongs to")
slug = slug = models.SlugField(unique=True) # this will be auto populated via admin panel, from title
title = baslik = models.CharField()
content = models.TextField()
start_time = models.DateTimeField()#start time for this entry.
end_time = models.DateTimeField()#end time for this entry.
@models.permalink
def get_absolute_url(self):
return ("entry.detail",(),{"city":self.area.city.slug,"area":self.area.slug,"entry":self.slug})
class Area(models.Model):
city = models.ForeignKey(verbose_name="city that this area belongs to")
name = models.CharField(max_length=30)
slug = models.SlugField(unique=True)# this will be auto populated via admin panel, from name
@models.permalink
def get_absolute_url(self):
return ("bolge.detay",(),{"city":self.city.slug,"area":self.slug})
def active_entry(self):
from datetime import datetime, date, time
now = datetime.now()
try:
return Entry.objects.get(area__exact=self,start_time__lte=now,end_time__gte=now)
except Entry.DoesNotExist:
return False
class City(models.Model):
name =models.CharField(max_length=30)
slug = models.SlugField(unique=True) # this will be auto populated via admin panel, from name
@models.permalink
def get_absolute_url(self):
return ("city.detail",(),{"city":self.slug})
请帮助这个可怜的灵魂配置他的 url 配置。
谢谢
Assume I have 3 Models: City, Area, Entry.
Each city has several Areas and each area can have several entries BUT for "now", there can be will be only one active Entry and it will be shown. So in logic:
Note that each city, area, entry will be using slug variable of related model class
Format will be in such:
www.mysite.com/<slug of city>/<slug of area>/<slug of entry>
www.mysite.com/mycity/myarea/
-> will be displaying an Entry that is bound to that Area AND active (this can be detected by using Area's active_entry
function).
But users can view some old Entries such as:
www.mysite.com/mycity/myarea/some-old-entry-that-is-no-longer-active
I have written get_absolute_url functions by reading the "Practical Django Projects 2nd Edition" book but now I am stucked.
I have such models:
from django.db import models
class Entry(models.Model):
area = models.ForeignKey('Area',verbose_name="The area that this entry belongs to")
slug = slug = models.SlugField(unique=True) # this will be auto populated via admin panel, from title
title = baslik = models.CharField()
content = models.TextField()
start_time = models.DateTimeField()#start time for this entry.
end_time = models.DateTimeField()#end time for this entry.
@models.permalink
def get_absolute_url(self):
return ("entry.detail",(),{"city":self.area.city.slug,"area":self.area.slug,"entry":self.slug})
class Area(models.Model):
city = models.ForeignKey(verbose_name="city that this area belongs to")
name = models.CharField(max_length=30)
slug = models.SlugField(unique=True)# this will be auto populated via admin panel, from name
@models.permalink
def get_absolute_url(self):
return ("bolge.detay",(),{"city":self.city.slug,"area":self.slug})
def active_entry(self):
from datetime import datetime, date, time
now = datetime.now()
try:
return Entry.objects.get(area__exact=self,start_time__lte=now,end_time__gte=now)
except Entry.DoesNotExist:
return False
class City(models.Model):
name =models.CharField(max_length=30)
slug = models.SlugField(unique=True) # this will be auto populated via admin panel, from name
@models.permalink
def get_absolute_url(self):
return ("city.detail",(),{"city":self.slug})
Please help this poor soul to configure his url configuration.
Thanks
