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,而不使用ModelForm.我的表单正在运行,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：’我陷入了困境,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})

解决方法

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,如果字段值不遵循约束,则保存对象可能会失败.所以你需要照顾它.
