在Django保存表单数据

Question

我试图在Django中设置一个表单并将数据保存到我的数据库，而不使用ModelForm。我的表单正在工作，但我坚持的部分是如何处理表单数据并将其保存在视图中。正如你所看到的，在'if form.is_valid（）'之后：'我被困住了，无法想到正确的代码。

# 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})

您需要创建对象并手动设置所有字段。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('/') 
     .... 

请注意，如果字段值不符合约束，则保存对象可能会失败。所以你需要照顾这一点。
