Export graph data about django-schema-graph

[rotten]

FWIW, I was able to grab the raw graph data this tool generates by using the wget command found in issue #49: #49 (comment) and then editing the index.html, and then post-processing it to a format gephi could use. It was more manual work than I had planned, which is why I thought it might make a nice feature.

It should be possible to create a view that returns the data in a format you like by taking inspiration from the existing view:

django-schema-graph/schema_graph/views.py

Lines 29 to 33 in f0b982c

	def get_context_data(self, **kwargs):
	schema = get_schema()
	json_converter = make_json_converter()
	kwargs["schema"] = json_converter.dumps(schema)
	return super().get_context_data(**kwargs)

In your case, I think you'll want something like:

from cattrs.preconf.json import make_converter as make_json_converter
from django.http import HttpResponse

from schema_graph.schema import get_schema


def schema_json(request):
     schema = get_schema()
     json_converter = make_json_converter()
     schema_json = json_converter.dumps(schema)
     return HttpResponse(schema_json, content_type="application/json")

This example returns the graph data as JSON, but if you want another format you should be able to do that in the view.
