django froms案例

以下是一个简单的 Django forms 案例：

models.py

from django.db import models

class Contact(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()
    message = models.TextField()

forms.py

from django import forms
from .models import Contact

class ContactForm(forms.ModelForm):
    class Meta:
        model = Contact
        fields = ['name', 'email', 'message']
        widgets = {
            'name': forms.TextInput(attrs={'class': 'form-control'}),
            'email': forms.EmailInput(attrs={'class': 'form-control'}),
            'message': forms.Textarea(attrs={'class': 'form-control'}),
        }

views.py

from django.shortcuts import render
from .forms import ContactForm

def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            form.save()
            return render(request, 'contact_success.html')
    else:
        form = ContactForm()
    return render(request, 'contact.html', {'form': form})

contact.html

<form method="POST">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit" class="btn btn-primary">Submit</button>
</form>

contact_success.html

<h1>Contact form submitted successfully!</h1>

上面的代码演示了如何创建一个简单的联系表单，将数据保存到数据库中，并在提交成功后重定向到一个成功页面。在这个例子中，使用了 Django forms 和 models，以及一些简单的 HTML 和 Bootstrap 样式。
