我有一个第一次运行 django-piston 的 Django 应用程序。
我已经为模型配置了一个处理程序,并且它被操纵用于 GET 和 POST。
GET 工作正常。久经考验。
然而,POST 很糟糕。当我向它发布数据时,我收到了这个错误
Responded: Piston/0.2.3rc1 (Django 1.2.4) crash report:
Method signature does not match.
Resource does not expect any parameters.
Exception was: cannot concatenate 'str' and 'dict' objects
我真的不是 Python 的专家,但一些基本的谷歌搜索显示这似乎是一个相当通用的 Python TypeError
所以这里有一些代码。
urls.py(相关部分)
auth = DjangoAuthentication()
ad = { 'authentication': auth }
word_handler = Resource(handler = WordHandler, **ad)
urlpatterns = patterns(
url(r'^word/(?P<word_id>[^/]+)/', word_handler),
url(r'^words/', word_handler),
)
handlers.py(相关部分)
class WordHandler(BaseHandler):
allowed_methods = ('GET','POST',)
model = Word
fields = ('string', 'id', 'sort_order', ('owner', ('id',)),)
def read(self, request, word_id = None):
"""
Read code goes here
"""
def create(self, request):
if request.content_type:
data = request.data
print("Words Data: " + data)
existing_words = Word.objects.filter(owner = request.user)
for word in data['words']:
word_already_exists = False
for existing_word in existing_words:
if word["string"] == existing_word.string:
word_already_exists = True
break
if not word_already_exists:
Word(string = word["string"], owner = request.user).save()
return rc.CREATED
基本上它甚至根本没有创建(),或者至少它似乎没有。它只是因上述错误而崩溃,所以我什至看不到它是如何接收数据的。
只是为了它,这是我要发布的数据
{"words":[{"owner":{"id":1,"tags":null,"password":null,"words":null,"email":null,"firstname":null,"lastname":null,"username":null},"id":1,"sort_order":0,"tags":null,"string":"Another Test"},{"owner":{"id":1,"tags":null,"password":null,"words":null,"email":null,"firstname":null,"lastname":null,"username":null},"id":2,"sort_order":0,"tags":null,"string":"Here's a test"},{"owner":null,"id":0,"sort_order":0,"tags":null,"string":"Tampa"}]}
任何信息都会非常有帮助。
