Django 提供了多种方式来回传表单数据,以下是几种常见的实现方式,每种方式都会详细介绍步骤流程并结合示例代码进行说明。
假设我们有一个简单的表单,用于用户提交姓名和电子邮件地址。
<!-- templates/form.html -->
<form method="post" action="{% url 'form_submission' %}">
{% csrf_token %}
<label for="name">Name:</label>
<input type="text" id="name" name="name"><br>
<label for="email">Email:</label>
<input type="email" id="email" name="email"><br>
<input type="submit" value="Submit">
</form>
步骤流程:
django.views.View
的类视图。示例代码:
# views.py
from django.views import View
from django.shortcuts import render
from .forms import MyForm
class MyFormView(View):
template_name = 'form.html'
def get(self, request):
form = MyForm()
return render(request, self.template_name, {'form': form})
def post(self, request):
form = MyForm(request.POST)
if form.is_valid():
name = form.cleaned_data['name']
email = form.cleaned_data['email']
# 处理数据...
return render(request, self.template_name, {'form': form})
步骤流程:
示例代码:
# views.py
from django.shortcuts import render
from .forms import MyForm
def my_form_view(request):
template_name = 'form.html'
form = MyForm()
if request.method == 'POST':
form = MyForm(request.POST)
if form.is_valid():
name = form.cleaned_data['name']
email = form.cleaned_data['email']
# 处理数据...
return render(request, template_name, {'form': form})
步骤流程:
django.views.generic.edit
导入 FormView
。FormView
的子类,并设置 form_class
属性。示例代码:
# views.py
from django.views.generic.edit import FormView
from .forms import MyForm
class MyFormView(FormView):
template_name = 'form.html'
form_class = MyForm
success_url = '/success/' # 成功提交后的跳转URL
def form_valid(self, form):
name = form.cleaned_data['name']
email = form.cleaned_data['email']
# 处理数据...
return super().form_valid(form)
这里只介绍了几种常见的方式,实际上还有其他方式,如使用 Django 的 ModelForm
来处理与数据库模型相关的表单。无论选择哪种方式,都要根据项目需求和代码结构来选择最合适的方法。
