Save form data in Django
提问by Casey
I'm trying to set up a form in Django and save the data to my database, without using a ModelForm. My form is working, but the part I am stuck on is how to process the form data and save it within the view. As you can see, after 'if form.is_valid():' I am stuck and cannot think of the right code.
我正在尝试在 Django 中设置一个表单并将数据保存到我的数据库中，而不使用 ModelForm。我的表单正在工作，但我遇到的问题是如何处理表单数据并将其保存在视图中。如您所见，在 'if form.is_valid():' 之后，我被卡住了，想不出正确的代码。
# models.py
from django.db import models
class Listing(models.Model):
business_name = models.CharField(max_length=80)
business_email = models.EmailField()
business_website = models.CharField(max_length=80)
business_phone = models.CharField(max_length=80)
# forms.py
from django import forms
class NewBusinessForm(forms.Form):
business_name = forms.CharField(label='Business Name', max_length=100)
business_phone = forms.CharField(label='Phone Number', max_length=100)
business_email = forms.EmailField(label='Email Address', max_length=100)
business_website = forms.CharField(label='Web Site', max_length=100)
# views.py
from django.shortcuts import render
from django.http import HttpResponseRedirect
from .forms import NewBusinessForm
def new_business(request):
if request.method == 'POST':
form = NewBusinessForm(request.POST)
if form.is_valid():
# process form data
return HttpResponseRedirect('/')
else:
form = NewBusinessForm()
return render(request, 'directory/new.html', {'form': form})

You need to create the object and set all fields manually. Here is an example.
您需要手动创建对象并设置所有字段。这是一个例子。
def new_business(request):
if request.method == 'POST':
form = NewBusinessForm(request.POST)
if form.is_valid():
# process form data
obj = Listing() #gets new object
obj.business_name = form.cleaned_data['business_name']
obj.business_email = form.cleaned_data['business_email']
obj.business_phone = form.cleaned_data['business_phone']
obj.business_website = form.cleaned_data['business_website']
#finally save the object in db
obj.save()
return HttpResponseRedirect('/')
....
Note that saving object may fail if field values do not follow the constraint. So you need to take care of that.
请注意，如果字段值不遵循约束，则保存对象可能会失败。所以你需要照顾它。

In Django 2.0, I think there is an easy way, use FormViewin class based view.
在 Django 2.0 中，我认为有一个简单的方法，在基于类的视图中使用FormView。
from django.views.generic.edit import FormView
class newBusiness(FormView):
form_class = NewBusinessForm
success_url ="/"
template_name = "temp.html"
def form_valid(self, form):
form.save()
return redirect(self.success_url )
I did not test it to run, but i think it will be OK. More at https://docs.djangoproject.com/en/2.0/topics/forms/modelforms/
我没有测试它运行，但我认为它会好的。更多信息请访问https://docs.djangoproject.com/en/2.0/topics/forms/modelforms/
