如何渲染POST并使其显示在另一页上

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我从POST表单获得的信息。 我想让我从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，我想要这个产品的“主题”（请看form.py）（例如1960法国主席）在另一个页面上显示。 http://bakersfield.craigslist.org/ata/}

我可以得到一些建议来处理提交的信息吗？ 这是现在的代码。我会感谢你的答案和帮助。

◆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>

我假设你的数据库中有一个Sell模型/表（你存储用户的“销售”），否则它没有任何意义。这意味着您可以节省一些时间并使用ModelForm, 而不是简单的Form。模型表单需要一个数据库表并为其生成一个html表单。

forms.py

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

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

在你views.py你需要显示您的用户有 发布给别人看的Sells一个多视图。你还需要一个html模板，这个视图将会显示每个Sell的上下文。

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 %} 

我们还需要为特定Sell

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)), 
) 

views.py的显示一个新的URL条目

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) 

这足以让你继续我的想法。有些模式可以让这些东西更加模块化，更好，但是我不想让你得到太多的信息，因为你是一个django初学者。
