python bottle framework - How to pass dictionary to nested template?

问题

I am using python's bottle framework to develop a simple web page. I am having trouble understanding how to pass a dictionary to a subtemplate. Example code:

mydictionary:

{
message: "Hello World",
...other template vars ... 
}

Router.py

@route('/index.html')
@view('index.tpl')
def index():
    return mydictionary

views/index.tpl

<body>
%include subpage1 ......  <-- need to pass mydictionary here
...other stuff ...
</body>

views/subpage1.tpl

<div>This is a test: {{message}}</div>

The documentation page states:

*The %include Statement: You can include other templates using the %include sub_template [kwargs] statement. The sub_template parameter specifies the name or path of the template to be included. The rest of the line is interpreted as a comma-separated list of key=statement pairs similar to keyword arguments in function calls. They are passed to the sub-template analogous to a SimpleTemplate.render() call. The **kwargs syntax for passing a dict is allowed too*:

However, no example is given on how to pass dictionary with this **kwargs to subtemplates. Anyone ever done this? If I just say %include subpage1 mydictionary, bottle complains mydictionary is undefined (even though mydictionary is a global dict [defined in Router.py]).

回答1:

I got around this by doing the following in the template file:

views/index.tpl

<body>
%from mydictfile import * <-- importing mydict here
%include subpage1 mydict  
...other stuff ...
</body>

mydictfile:

mydict = {
message: "Hello World",
...other template vars ... 
}

This seems to be working for me.

回答2:

You need keyword arguments. try:

%include subpage1 mydict=mydict ...

回答3:

As a variation on @G.A.'s answer, I accessed a variable defined in my main program in my template with:

% from __main__ import app
blah blah {{app.config.my_config}} blah

Edit: Under Python 2.6 I had to use (to import from mybottleapp.py):

% from mybottleapp import app

I am not enough of a Python expert to understand why this is so.
