with LogicContext():
    db = get_context().get_mongo()
    cache = get_context().get_redis()

        val = self.session(key)
        self.session(key,val)

test command

run_test(test_city.DemoCase.testprint) :test testprint method
run_test(test_city.DemoCase)           :test methods in DemoCase class
run_test(test_city)                    :test methods in test_city.py
run_test(all )                         :test methods in app's __conf__.UTEST_DIR

pro command

pro_test(test_city.DemoCase.testprint) :profile testprint method
pro_test(test_city.DemoCase)           :profile methods in DemoCase class
pro_test(test_city)                    :profile methods in test_city.py

kpages)How to use uimodule and uimethod in kpages

1. kpages can auto find  Ui_Module's subclass in ACTION_DIR
2. you can use {% module dir_modulename_classname() %} to call Ui Module
Demo Code
    Class Demo(tornado.web.UIModule):
        def render(self,name):
            return self.render('<h1>Hello world:{0}</h1>'.format(name))

Template code
    {% module Demo('kpages') %}


3. @reg_ui_method in ACTION_DIR's files, to apply Ui methods
Demo code

    @reg_ui_method(name='testmethod',intro='demo for ui method')
    def add(self,a,b):
        return a+b

Template code
    {{ add(3,4) }}
