我刚刚安装了 Pyramid 框架(按照教程。我从“alchemy”脚手架(pcreate -s alchemy myproject)开始创建了一个新项目并运行了 setup.py 脚本。出于某种原因,当我运行 pserve 时,我得到了一个TopLevelLookupException,说明它找不到 uri 'pyramid_debugtoolbar:templates/exception_summary.dbtmako' 的模板:
TopLevelLookupException: Can not locate template for uri 'pyramid_debugtoolbar:templates/exception_summary.dbtmako'
文件“mytemplate.pt”在目录中,但由于某种原因,我仍然收到此错误。
这是初始化.py:
from pyramid.config import Configurator
from sqlalchemy import engine_from_config
from .models import (
DBSession,
Base,
)
def main(global_config, **settings):
""" This function returns a Pyramid WSGI application.
"""
engine = engine_from_config(settings, 'sqlalchemy.')
DBSession.configure(bind=engine)
Base.metadata.bind = engine
config = Configurator(settings=settings)
config.add_static_view('static', 'static', cache_max_age=3600)
config.add_route('home', '/')
config.scan()
return config.make_wsgi_app()
这是views.py:
from pyramid.response import Response
from pyramid.view import view_config
from sqlalchemy.exc import DBAPIError
from .models import (
DBSession,
MyModel,
)
@view_config(route_name='home', renderer='/templates/mytemplate.pt')
def my_view(request):
try:
one = DBSession.query(MyModel).filter(MyModel.name == 'one').first()
except DBAPIError:
return Response(conn_err_msg, content_type='text/plain', status_int=500)
return {'one': one, 'project': 'Triumph'}
conn_err_msg = """error"""
这是models.py文件:
from sqlalchemy import (
Column,
Integer,
Text,
)
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import (
scoped_session,
sessionmaker,
)
from zope.sqlalchemy import ZopeTransactionExtension
DBSession = scoped_session(sessionmaker(extension=ZopeTransactionExtension()))
Base = declarative_base()
class MyModel(Base):
__tablename__ = 'models'
id = Column(Integer, primary_key=True)
name = Column(Text, unique=True)
value = Column(Integer)
def __init__(self, name, value):
self.name = name
self.value = value
