django-query-parser
A django app to parse queries written outside the django app.
Idea
Some queries are controls the business case, so it will be benefical if they are can saved outside the application like in a config file or a database so the logic can be changed without changing the code.
Samples
- to write an 'or'
{"or":{"status_id" : 3, "name__icontains":"Ahmed"}}
- to write negation
{"or":{"status_id" : 3, "~name__icontains":"Ahmed"}}
- to write an 'and'
{"and":{"status_id" : 3, "name__icontains":"Ahmed"}}
or{"status_id" : 3, "name__icontains":"Ahmed"}
