在 python 中使用多级 JSON/dict/Template 推进字符串/JSON 格式化

Question

I want to replace text in 1 JSON using the keys mapped from a second json. Both the JSONs are dynamic and first JSON can be modified to use keys from second JSON.

text_to_replace = json.dumps([{"type": "data", "layerName": "THIS IS Mohit", "property": "Source Text", "expression": "time > 4 ? 'This is {groom.first_name}' : 'This is {groom.first_name}'", "composition": "01 Oliver"}, {"type": "data", "layerName": "THIS IS {bride.first_name}", "property": "Source Text", "expression": "time > 4 ? 'This is Aashi' : 'This is {bride.first_name}'", "composition": "02 Amelia"}, {"type": "data", "layerName": "January 2020", "property": "Source Text", "expression": "time > 4 ? '21st January 2021' : '21st January 2021'", "composition": "03 November"}, {"type": "data", "layerName": "JANUARY 2020", "property": "Source Text", "expression": "time > 4 ? '21st January 2021' : '21st January 2021'", "composition": "02 Date"}])




context = {'function_list': [
            {'name': 'Xbbd', 'venue': 'Xbxb\nXnx', 'time': '06:00 AM', 'date': '19th April 2020',

I tried using python string formatting using Template class but it doesn't seems to support complex dict.

from string import Template
s = Template("$bride['name'] likes what")
temp_json = {'bride': {'name': 'ishita'}}
print('temp_dict', type(temp_json))
temp = s.safe_substitute(temp_json)
print('string', s)
print('string', temp)

It is not working. Any suggestions about what else can I try to do this.

Answer 1

def test(self):
    from django.template import Context, Template
    template = Template("My name is {{ my_name }}.")
    context = Context({"my_name": "Ujjwal"})
    string = template.render(context)
    print('string', string)

I am using Django template engine instead. It by default has support for complex JSON.
