How to render templates with jinja2 using json in python?

Question

I'm trying to directly load json data to render templates using jinja2 and I'm having trouble doing so without hardcoding values. For example,

msg = template.render(posts=config[0]['context']['posts'])

Here, I've hardcoded the variable "posts" which exists in my json file and "config" is simply a python dict that I've loaded the json data into. Here's a snippet of the json file:

[
  {
    "url": "/",
    "template": "index.html",
    "context": {
      "logname": "gjgk",
      "posts": [
        {
          "postid": "3",
          "owner": "ggkghj",
          "likes": 1,
          "comments": [
            {
              "owner": "dsf",
              "text": "#sadf"
            }
          ]
        }
]

If "posts" was named something else, how would I reflect this in my python code? Should I change the variable names written in my template file?

Thanks

Can you add template to the post.

I figured out the solution. I used kwargs:

for x in config[0]['context']:
        msg = template.render(**{x:config[0]['context'][x]})
