from django.shortcuts import render
from django.http import HttpResponse 
from .forms import contactForm
from django.forms import ModelForm
from django.core.mail import send_mail

def contact(request):
    if request.method == 'GET':
        form = contactForm()
    else:
        form = contactForm(request.POST)
        if form.is_valid():
            form.save()
            name = form.cleaned_data['name']
            email = form.cleaned_data['email']
            Phonenumber = form.cleaned_data['Phonenumber']
            try:
                send_mail(subject, message, from_email,['admin@example.com'])
            except BadHeaderError:
                return HttpResponse('Invalid header found.')
            return redirect('success')
    return render(request, "contact-form.html", {'form': form})

我的表单.py

from django import forms
from django.core.validators import RegexValidator
# from django.forms import contactForm
from .models import contactForm



class contactForm(forms.ModelForm):

    name = forms.CharField(max_length=100,widget=forms.TextInput(attrs={'class' : 
    'form-control col-lg-12', 'placeholder': 'Name'}), label='')
    email = forms.EmailField(widget=forms.TextInput(attrs={'class' : 'form-control col-lg-12', 'placeholder': 'Email'}), label='')
    Phonenumber = forms.CharField(max_length=10, validators= [RegexValidator(r'^\d{1,10}$')], widget=forms.TextInput(attrs={'class' : 'form-control col-lg-12', 'placeholder': 'Mobile'}), label='')

    class contactForm(forms.ModelForm):
      class Meta:      
            model = contactForm
            fields = '__all__'

我的模型.py

from django.db import models
from django.forms import ModelForm
from django.core.validators import RegexValidator

class contactForm(models.Model):
    name = models.CharField(max_length=255)
    Phonenumber = models.CharField(max_length=10, validators=[RegexValidator(r'^\d{1,10}$')])
    email = models.EmailField(max_length=254)

首先，您应该发布一些类似 forms.py 的代码以进行澄清，但看到错误消息，它显示 django.forms import contactForm cannot import name 'contactForm' from 'django.forms'。似乎 contactForm 是名称您要在其上塑造表单的模型。 作为模型，我们如何从 django.forms 导入它？ 使用此代码；

from .models import contactForm
from django.forms import modelForm #modelForm helps to create forms from models


class yourForm(modelForm):
    class Meta:
        model = contactForm #here we provide the name of the model from which the form is to be inherited
        fields = ('here_provide_the_name_of_the_fields_of_the_model_which_you_want_to_Include_in_the_form')

不同的字段将被放置为字段元组的不同元素。 如果您想在表单中包含所有字段；

fields = __all__
