    总是错误
    self.render_template('testjinja2.html',name='google')
    TypeError: render_template() takes exactly 1 argument (3 given)

    self.render_template

    这个self是从哪儿来的?

    要么定义
    def render_template(self, filename, **context):

    要么调用的时候不要通过self调用

    这是一个python函数使用问题,和jinja没有关系。

    def render_template(self, filename, **context):

    我添加了self后,输出变成空白了
