Question

我正在尝试创建类似于craigslist的市场网站。我根据Django教程“使用表单”创建了一个表单，但我不知道如何呈现从POST表单中获取的信息。我希望从POST获得的信息（主题，价格......等）显示在另一个页面上。 http://bakersfield.craigslist.org/atq/3375938126.html并且，我希望此产品的“主题”（请查看form.py）（例如，1960年法国主席）显示在此类其他页面上。 http://bakersfield.craigslist.org/ata/}

我可以获得处理提交信息的建议吗？这是现在的代码。我会感谢您的所有答案和帮助。

◆forms.py

from django import forms

class SellForm(forms.Form):
    subject = forms.CharField(max_length=100)
    price = forms.CharField(max_length=100)
    condition = forms.CharField(max_length=100)
    email = forms.EmailField()
    body = forms.TextField()

◆views.py

from django.shortcuts import render, render_to_response
from django.http import HttpResponseRedirect
from site1.forms import SellForm

def sell(request):

    if request.method =="POST":
        form =SellForm(request.POST)
        if form.is_valid():
            subject = form.cleaned_data['subject']
            price = form.cleaned_data['price']
            condition = form.cleaned_data['condition']
            email = form.cleaned_data['email']
            body = form.cleaned_data['body']

            return HttpResponseRedirect('/books/')

    else:
        form=SellForm()

    render(request, 'sell.html',{'form':form,})

◆urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^sechand/$','site1.views.sell'),
    url(r'^admin/', include(admin.site.urls)),

)

◆sell.html

<form action = "/sell/" method = "post">{% csrf_token%} 
{{ form.as_p }}
<input type = "submit" value="Submit" />
</form>

我假设您的数据库中存在Sell模型/表（存储用户的“销售”），否则没有任何意义。这意味着您可以节省一些时间并使用ModelForm，而不是简单的Form。模型表单获取数据库表并为其生成html表单。

<强> forms.py

from django.forms import ModelForm
from yourapp.models import Sell

class SellForm(ModelForm):
    class Meta:
        model = Sell

在views.py中，您还需要一个显示用户所拥有的Sells的视图张贴给别人看。您还需要一个html模板，该视图将使用每个Sell的上下文进行渲染。

<强> sell_display.html

{% extends 'some_base_template_of_your_site.html' %}
{% block content %}
<div id="sell">
  <h3> {{ sell.subject }}</h3>
  <p> {{ sell.condition }}</p>
  <p> {{ sell.body }}</p>
  <!-- the rest of the fields.. -->
</div>
{% endblock %}

我们还需要一个新的网址条目来显示特定的Sell

<强> urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Changed `sell` view to `sell_create`
    url(r'^sechand/$','site1.views.sell_create'),
    # We also add the detail displaying view of a Sell here
    url(r'^sechand/(\d+)/$','site1.views.sell_detail'),
    url(r'^admin/', include(admin.site.urls)),
)

<强> views.py

from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response, get_object_or_404
from yourapp.models import Sell
from yourapp.forms import SellForm

def sell_detail(request, pk):
    sell = get_object_or_404(Sell, pk=int(pk))
    return render_to_response('sell_display.html', {'sell':sell})

def sell_create(request):
    context = {}
    if request.method == 'POST':
        form = SellForm(request.POST)
        if form.is_valid():
            # The benefit of the ModelForm is that it knows how to create an instance of its underlying Model on your database.
            new_sell = form.save()   # ModelForm.save() return the newly created Sell.
            # We immediately redirect the user to the new Sell's display page
            return HttpResponseRedict('/sechand/%d/' % new_sell.pk)
    else:
        form = SellForm()   # On GET request, instantiate an empty form to fill in.
    context['form'] = form
    return render_to_response('sell.html', context)

这足以让你走了我想。有一些模式可以让这些东西更加模块化和更好，但是我不想给你太多信息，因为你是django的初学者。
