Here's the code I used - I had to copy a LOT of stuff. https://gist.github.com/simonw/281eac9c73b062c3469607ad86470eb2 I'm going to move this work into a new, separate issue. | { "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |

Here's where I've got to now - I'm systematically working through the variables that are returned for HTML and for JSON copying across code to get it to work: ```python from datasette.database import QueryInterrupted from datasette.utils import escape_sqlite from datasette.utils.asgi import Response, NotFound, Forbidden from datasette.views.base import DatasetteError from datasette import hookimpl from asyncinject import AsyncInject, inject from pprint import pformat class Table(AsyncInject): @inject async def database(self, request, datasette): # TODO: all that nasty hash resolving stuff can go here db_name = request.url_vars["db_name"] try: db = datasette.databases[db_name] except KeyError: raise NotFound(f"Database '{db_name}' does not exist") return db @inject async def table_and_format(self, request, database, datasette): table_and_format = request.url_vars["table_and_format"] # TODO: be a lot smarter here if "." in table_and_format: return table_and_format.split(".", 2) else: return table_and_format, "html" @inject async def main(self, request, database, table_and_format, datasette): # TODO: if this is actually a canned query, dispatch to it table, format = table_and_format is_view = bool(await database.get_view_definition(table)) table_exists = bool(await database.table_exists(table)) if not is_view and not table_exists: raise NotFound(f"Table not found: {table}") await check_permissions( datasette, request, [ ("view-table", (database.name, table)), ("view-database", database.name), "view-instance", ], ) private =… | { "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |

This didn't work: ```python from datasette.utils.asgi import Response from datasette import hookimpl import html async def table(request): return Response.html("Hello from {}".format( html.escape(repr(request.url_vars)) )) @hookimpl def register_routes(): return [ (r"/(?P<db_name>[^/]+)/(?P<table_and_format>[^/]+?$)", table), ] ``` I'll use a `/t/` prefix for the moment, but this is probably something I'll fix in Datasette itself later. | { "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |

It will reuse the existing HTML template but will be a completely new Python implementation, based on `asyncinject`. I'm going to start by just getting the table to show up on the page - then I'll add faceting, suggested facets, filters and so-on. Bonus: I'm going to see if I can get it to work for arbitrary SQL queries too (stretch goal). | { "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |
