Question

我正在尝试构建一个仪表板，我有登录/注销部分，但有很多概念我仍然不太明白。就在这一刻，我正在努力建立这个：

我有一个带有项目列表的仪表板（listview）。那些物品来自我建造的模型。要查看该仪表板，您需要登录（我已经具备此“登录”功能）。
我需要将这些项目中的每一项链接到一个表单，我可以在其中更新这些项目的信息（updateview）。提交时，我想显示成功消息或错误消息。
在仪表板中，我需要一个链接到createview表单的按钮。

这是一个应用程序，允许用户创建优惠，并在Facebook上作为Facebook应用程序在他们的粉丝中发布。

我遇到的问题是我不明白如何将视图，表单和网址放在一起以显示我想要的内容。

有什么我想念的吗？对不起，如果这个问题太愚蠢了。

我正在使用基于类的视图来构建它。这是我正在使用的代码：

在我的model.py中：



from django.db import models

from django.contrib.auth.models import User

# Create your models here.
class Offer(models.Model):
    offer_owner = models.ForeignKey(User, related_name="offers")
    created_at = models.DateTimeField(auto_now_add=True, editable=False)
    updated_at = models.DateTimeField(auto_now=True, editable=False)
    business_name = models.CharField(max_length=255, verbose_name="nombre de la empresa")
    offer_title = models.CharField(max_length=255, verbose_name="titulo de la oferta")
    offer_date_from = models.DateTimeField(null=True, blank=False, editable=True, auto_now_add=False, verbose_name="fecha en que inicia la oferta")
    offer_date_to = models.DateTimeField(null=True, blank=False, editable=True, auto_now_add=False, verbose_name="fecha en que finaliza la oferta")
    offer_detail = models.TextField(verbose_name="detalles de la oferta")
    offer_terms = models.TextField(verbose_name="terminos de la oferta")
    published = models.BooleanField(default=True, verbose_name="esta oferta esta publica")
    from_fanpage = models.CharField(max_length=255, verbose_name="nombre del fanpage") #fanpage info
    fanpage_id = models.BigIntegerField(verbose_name="fanpage id")
    fanpage_url = models.URLField(verbose_name="fanpage url")

    def __unicode__(self):
        return self.offer_title

from django.db import models from django.contrib.auth.models import User # Create your models here. class Offer(models.Model): offer_owner = models.ForeignKey(User, related_name="offers") created_at = models.DateTimeField(auto_now_add=True, editable=False) updated_at = models.DateTimeField(auto_now=True, editable=False) business_name = models.CharField(max_length=255, verbose_name="nombre de la empresa") offer_title = models.CharField(max_length=255, verbose_name="titulo de la oferta") offer_date_from = models.DateTimeField(null=True, blank=False, editable=True, auto_now_add=False, verbose_name="fecha en que inicia la oferta") offer_date_to = models.DateTimeField(null=True, blank=False, editable=True, auto_now_add=False, verbose_name="fecha en que finaliza la oferta") offer_detail = models.TextField(verbose_name="detalles de la oferta") offer_terms = models.TextField(verbose_name="terminos de la oferta") published = models.BooleanField(default=True, verbose_name="esta oferta esta publica") from_fanpage = models.CharField(max_length=255, verbose_name="nombre del fanpage") #fanpage info fanpage_id = models.BigIntegerField(verbose_name="fanpage id") fanpage_url = models.URLField(verbose_name="fanpage url") def __unicode__(self): return self.offer_title

在我的forms.py中：

from django import forms
from django.forms import ModelForm
from models import Offer, Consumer

# Login Form

#class LoginForm(forms.Form):
#   username = forms.EmailField()
#   password = forms.CharField(widget=forms.PasswordInput())

class OfferForm(ModelForm):
    class Meta:
        model = Offer
        exclude = ["offer_owner"]

class ConsumerForm(ModelForm):
    class Meta:
        model = Consumer
        # exclude = ["offer_obtained", ""]

在我的views.py中：

from django import forms from django.forms import ModelForm from models import Offer, Consumer # Login Form #class LoginForm(forms.Form): # username = forms.EmailField() # password = forms.CharField(widget=forms.PasswordInput()) class OfferForm(ModelForm): class Meta: model = Offer exclude = ["offer_owner"] class ConsumerForm(ModelForm): class Meta: model = Consumer # exclude = ["offer_obtained", ""]

在我的urls.py中：

    }
    return render(request, template_name, context)

在我的模板中：这是主视图，我在其中放置了项目列表



from django.conf.urls import patterns, include, url

# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

from offers.views import *

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'thesocialbrand.views.home', name='home'),
    # url(r'^thesocialbrand/', include('thesocialbrand.foo.urls')),
    url(r'^dashboard/', OfferListView.as_view(), name='dashboard'),
    url(r'^dashboard/edit/(?P<pk>\d+)/$', OfferUpdateView.as_view(), name="edit"),
    # url(r'^dashboard/(?P<pk>\d+)/$', dashboard_offer_detail),
    # url(r'^app/', app_public, name='app'),
    url(r'^app/(?P<pk>\d+)/$', app_public),
    url(r'^login/', login_usr, name='login'),
    url(r'^logout/', logout_usr, name='logout'),
)

from django.conf.urls import patterns, include, url # Uncomment the next two lines to enable the admin: # from django.contrib import admin # admin.autodiscover() from offers.views import * urlpatterns = patterns('', # Examples: # url(r'^$', 'thesocialbrand.views.home', name='home'), # url(r'^thesocialbrand/', include('thesocialbrand.foo.urls')), url(r'^dashboard/', OfferListView.as_view(), name='dashboard'), url(r'^dashboard/edit/(?P<pk>\d+)/$', OfferUpdateView.as_view(), name="edit"), # url(r'^dashboard/(?P<pk>\d+)/$', dashboard_offer_detail), # url(r'^app/', app_public, name='app'), url(r'^app/(?P<pk>\d+)/$', app_public), url(r'^login/', login_usr, name='login'), url(r'^logout/', logout_usr, name='logout'), )

这是我的表单的更新视图的视图。单击列表中的某个项目后，我的表单的详细信息。

{% load url from future %}

<h1>Dashboard</h1>
<h4>Hola {{ user }}</h4>
<a href="/offers/logout/">Logout</a>
<h3>Mis ofertas</h3>
<ul>
    {% for offer in offer_list %}
    <li><a href="{% url 'edit' offer.pk %}">{{ offer.offer_title }}</a></li>
    {% empty %}
    <li>Sorry, no offers yet. Check back soon!</li>
    {% endfor %}
</ul>

当我完成这个时，我会在我的博客中写一篇文章，解释我发现的所有这些内容。对于处于同样情况的其他初学者来说，它肯定会有用，也许需要建立类似的东西。
