Question

我正在试图弄清楚为我的api创建非orm端点是否有意义。我已经看过Docs中的“使用非ORM数据源的Tastypie”部分，但我正在考虑更多关于处理表单等问题。例如：将数据传递到将处理和发送电子邮件的端点。我不会保存任何东西到数据库，我只是想验证表格并发送它。我在文档中遗漏了什么，或者我只是在咆哮错误的树？

我认为您可以在views.py中定义一个函数并处理请求而不使用tastypie：

这是一个将新用户注册到Django webapp的示例;您可以通过处理请求中的表单数据来重新调整它以发送电子邮件。

# In views.py:
...
from django.http import HttpResponse
from django.contrib.auth.models import User, Group
from django.contrib.auth import authenticate
from django.http import Http404
from django.utils import timezone
from models import *
from api import *
from django.utils import simplejson
...

# REST endpoint for user registration
# Enforces server-side mediation (input validation)
# On failure, raises Http404
# On success, redirects to registration success page
def register_user(request):
    if request.method != 'POST':
        raise Http404('Only POSTs are allowed')

    # acquire params
    username = request.POST['username']
    password = request.POST['password']
    repeatpw = request.POST['repeatpw']
    first_name = request.POST['first_name']
    last_name = request.POST['last_name']

    # Server-side mediation to check for invalid input
    if username == '' or username is None:
        raise Http404('Server-side mediation: Invalid Username')

    if len(username) > 30:
        raise Http404('Server-side mediation: username must be 30 characters or fewer')

    if len(first_name) > 30:
        raise Http404('Server-side mediation: first name must be 30 characters or fewer')

    if len(last_name) > 30:
        raise Http404('Server-side mediation: last name msut be 30 characters or fewer')

    if len(password) < 4:
        raise Http404('Server-side mediation: Password too short')

    if password != repeatpw:
        raise Http404('Server-side mediation: Password Mismatch')

    # This try-except block checks existence of username conflict
    try:
        test_user_exists = User.objects.get(username__exact=username)
        if test_user_exists != None:
            raise Http404('Server-side mediation: Username exists')
    except User.DoesNotExist:
        pass

    # Input passes all tests, proceed with user creation
    user = User.objects.create_user(username, 'default@nomail.com', password)
    group = Group.objects.get(name='Standard')
    user.first_name = first_name
    user.last_name = last_name
    user.groups.add(group)
    user.is_staff = False    
    user.save()

    # Build confirmation JSON
    confirmation = {
            'action': 'register_user',
            'username': username,
            'success': 'yes',
    }

    json_return = simplejson.dumps(confirmation)

    # return JSON of the success confirmation
    return HttpResponse(json_return, mimetype='application/json')

Tastypie，非orm端点
