Django表单输入不显示在前端/html

Question

我正在用django表单为一家冰淇淋公司创建一个软件，我在我的django表单上出现在我网站的前端有麻烦。我可以显示客户信息，但是客户的订单没有显示，我很困惑发生了什么。

orderentry.html

<!--Basic Customer Information--> 
<form method = "post">
{% csrf_token %}
{{ form.as_p }}
{{ newOrder}}
<button type = "submit">Place your order!</button> 
</form>

views.py

from django.http.response import HttpResponseRedirect
from django.shortcuts import render, redirect
from django.http import HttpResponse
import orderentry
from orderentry.forms import customerForm, customerInformation
def getCustomerInfo(request):
form = customerForm(request.POST)
if request.method == 'POST':
if form.is_valid():
form.save()
orderentry.forms.customer_first_name = form.cleaned_data['customer_first_name']
orderentry.forms.customer_last_name = form.cleaned_data['customer_last_name']
orderentry.forms.shipping_address = form.cleaned_data['shipping_address']
orderentry.forms.billing_address = form.cleaned_data['billing_address']
return redirect('/orderentry')
else:
form=customerForm()

return render(request, 'orderentry.html', {'form' : form})
def getCustomerOrder(request):
newOrder = customerInformation(request.POST)
if request.method == 'POST':
if newOrder.is_valid():
newOrder.save()
#orderentry.forms.order_Item_Flavor = newOrder.cleaned_data['order_Item_Flavor']
orderentry.forms.half_Pint_Count = newOrder.cleaned_data['half_Pint_Count']
orderentry.forms.one_Quart_Count = newOrder.cleaned_data['one_Quart_Count']
orderentry.forms.pint_Count = newOrder.cleaned_data['pint_Count']
orderentry.forms.half_Gallon_Count = newOrder.cleaned_data['half_Gallon_Count']
orderentry.forms.gallon_Count = newOrder.cleaned_data['gallon_Count']
orderentry.forms.cost = newOrder.cleaned_data['cost']
return redirect('/orderentry')
else:
print("error")
else:
newOrder=customerInformation()

return render(request, 'orderentry.html', {'newOrder' : newOrder})

order_Item_Flavor = models.ForeignKey('inventory.item', on_delete=models.CASCADE)
half_Pint_Count = models.IntegerField(default=0)

customer = models.ForeignKey(customerInfo, on_delete=models.CASCADE, default = 0)
def __str__(self):
return '%s, Half Pint: %s, Quart: %s, Pint: %s, Half Gallon: %s, Gallon: %s, $%s' % (self.order_Item_Flavor, 
self.half_Pint_Count, self.one_Quart_Count, self.pint_Count, self.half_Gallon_Count, self.gallon_Count, 
self.cost)

urls . py

from django.urls import path
from . import views
urlpatterns = [
path('', views.getCustomerInfo, name = 'orderentry'),
path('', views.getCustomerOrder, name = 'orderentry'),

基本上，这就是它看起来的样子，我不确定如何在前端显示customerInformation。前端

提前感谢任何帮助或指导，这是非常感激!

您可能认为getCustomerOrder被正确调用，但当您访问orderentry.html时它不会被调用(我不为这个文件提供url)。这意味着newOrder没有传递到模板(您的orderentry.html)。

所以，你必须将newOrder传递给你的模板getCustomerInfo:

# inside getCustomerInfo func (I omitted other code)
else:
newOrder=customerInformation() # you used 'newOrder', so I'm using the same name. You can change it, of course.
form=customerForm()
return render(request, 'orderentry.html', {'form' : form, "newOrder": newOrder}) # notice! you have to put 'newOrder' in this dictionary (or context).

到目前为止，当用户点击"下订单"时，您的订单信息不会保存!"按钮。因此，您必须将getCustomerOrder中if request.method == 'POST':之后保存顺序的代码放入getCustomerInfo中。
