我得到了以下非常基本的模板:
<html>
<head>
</head>
<body>
<div>
<!-- Using "for" to iterate through potential pages would prevent getting empty strings even if only one page is returned because the "page" is not equal the query, it is a subcomponent of the query -->
<div>{{ page.name }}</div>
<div>{{ page.leftText }}</div>
<div>{{ page.imageURL }}</div>
<div>{{ page.rightText }}</div>
</div>
</body>
</html>
最基本的模型是:
class Page(db.Model):
name = db.StringProperty(required=True)
leftText = db.TextProperty()
rightText = db.TextProperty()
imageURL = db.LinkProperty()
最基本的处理程序:
class BaseRequestHandler(webapp.RequestHandler):
#######
class PageContentLoadRequestHandler(BaseRequestHandler):
def renderPage(self, values):
directory = os.path.dirname(__file__)
path = os.path.join(directory, 'templates', 'simple_page.html')
return template.render(path, values, True)
def get(self):
page = db.get('aghwc21vZWJlbHIKCxIEUGFnZRgBDA')
#alternative code
# page db.get(db.key(self.request.get('key')))
# The solution is to call/fetch the wanted object/query
data = page.get() # or ... = Page.gql("GQL CODE").fetch(1)
values = {'page': page}
template_name = "simple_page.html"
return self.response.out.write(self.renderPage(values))
密钥只是从我的存储中随机取出的,它是已填充实体的真实现有密钥。
They idea is to load a page content dynamically into the doc via AJAX, problem is, that this handler returns an empty template.
无错误、200 HTTP代码、密钥存在等。
我完全崩溃了,对这样的问题有点恼火,因为我安静不知道故障可能在哪里。
当做,
EDIT: Changing the template values to there correct names, I now get the following erro:
values = {'page': page, 'name': page.name,}
AttributeError: 'NoneType' object has no attribute 'name'
