Pyramid - 是否可以在我的视图可调用中将我的 mako 模板呈现为字符串？

Question

I have a view callable that does looks similar to:

def post_comment(request):
    """ Posts the users comment to the thread """

    try:
        new_comment = comments.post()
    except InvalidComment as e:
        return {'success' : False, 'message' : e.message}

    # need to do something like:
    new_comment = pyramid.template.render(new_comment)

    return {'success' : True, 'message' : new_comment}

The route config for this view callable is:

config.add_route('post_comment',
                 '/comments/{link_id}/post',
                 view='site.views.post_comment',
                 view_renderer='json')

Using this, I can AJAXify my comment submissions and have a shiny web 2.0 website. The problem is, I'd like to render new_comment through my mako template to build the HTML and return that. However, I can't find a way to do this.

How can I render a mako template within my view callable to return the HTML as a JSON response?

You can call render directly using the documented Pyramid API here: http://docs.pylonsproject.org/projects/pyramid/1.0/api/renderers.html#pyramid.renderers.render

from pyramid.renderers import render

def my_view(request)
    renderer_dict = {} # dictionary of values to pass to the renderer
    new_comment = render('new_comment.mako', renderer_dict, request)
    …

I'm not sure I understand your question but I think you need 2 views, one for json and another for the mako one. For the mako view follow the official docs and mmerickel's answer. If you want to have multiple view callables within the same class you can have a look to pyramid_handlers .
