我是Django的新手.我正在尝试使用模板在我的索引视图中显示我的Project模型中的数据.我尽力构建这个应用程序类似于民意调查应用程序.我不确定我做错了什么.我使用的是python 2.7和django 1.8.6
这是我的网址：
from django.conf.urls import url
from . import views
app_name = 'project'
urlpatterns = [
url(r'^$',views.IndexView.as_view(),name='index'),url(r'^(?P这是我的模型：
import datetime
from django.db import models
from django.utils.encoding import python_2_unicode_compatible
from django.contrib.auth.models import User
from django.utils import timezone
@python_2_unicode_compatible # only if you need to support Python 2
class Contractor(models.Model):
#project
name = models.CharField(max_length=50)
address = models.CharField(max_length=100,blank=True)
phone = models.CharField(max_length=14,blank=True)
city = models.CharField(max_length=60,blank=True)
state = models.CharField(max_length=2,blank=True)
created_by = models.ForeignKey(User,related_name='Contractor_created_by')
created_date = models.DateTimeField()
modified_by = models.ForeignKey(User,related_name='Contractor_modified_by')
modified_date = models.DateTimeField()
def __str__(self):
return self.name
@python_2_unicode_compatible # only if you need to support Python 2
class Project(models.Model):
name = models.CharField(max_length=50)
jobNumber = models.CharField(max_length=8)
shopOut = models.DateTimeField(null=True)
shopIn = models.DateTimeField(null=True)
delivery = models.DateTimeField(null=True)
job1 = models.CharField(max_length=50,null=True)
job2 = models.CharField(max_length=50,null=True)
job3 = models.CharField(max_length=50,null=True)
contractor = models.ForeignKey(Contractor,on_delete=models.CASCADE,default=101)
created_by = models.ForeignKey(User,related_name='Project_created_by')
created_date = models.DateTimeField(auto_now_add=True)
modified_by = models.ForeignKey(User,related_name='Project_modified_by')
modified_date = models.DateTimeField(auto_now=True)
def __str__(self):
return self.name
def save(self,*args,**kwargs):
if not self.id:
self.created_by = User.objects.get(id=1)
self.modified_by = User.objects.get(id=1)
super(Project,self).save(*args,**kwargs)
year = datetime.datetime.now().year
self.jobNumber = '{}{:04d}'.format(year,self.id)
self.modified_by = User.objects.get(id=1)
super(Project,**kwargs)
这是我的观点：
from django.shortcuts import get_object_or_404,render
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.views import generic
from django.utils import timezone
from .models import Project
# Create your views here.
class IndexView(generic.ListView):
model = Project
template_name = 'project/index.html'
def get_queryset(self):
return Project.objects
class DetailView(generic.DetailView):
model = Project
这是我的模板：
{% load staticfiles %}
当我进入页面时,我得到一个h1项目,一个空的ul,以及一行显示’end of list’
最佳答案
在get_queryset中,您应该返回Project.objects.all().
原文链接：https://www.f2er.com/python/438486.html在模板中,您不需要执行project.get_queryset,为您调用get_queryset方法,并将值作为object_list和< objectname> _list以及其他参数传递给模板.在您的情况下,对象是Project,因此应该有一个project_list变量以及object_list.
你可以做：
{% for project in project_list %}
要么：
{% for project in object_list %}
