Easier way to manually apply column filters

[techniq]

I have a situation where I've added a column filter to a view and would like to manually apply it in a request. For example, with the following view:

class LineItemView(ModelView):
    column_filters = [FilterEqual(models.LineItem.invoice_id, "parent")]

to apply the filter via url, I need to use something like /admin/lineitem/?flt0_0={{request.args["id"]}}, which is confusing, and reliant on knowing the index position of the filters you want to apply.

Since this is an instance filter with a name ("parent") and a specific filter (FilterEqual) instead of a genearl column name (ex. ['foo']), it would be nice if you could apply the filter like this:
/admin/lineitem/?flt_admin={{request.args["id"]}}

For the cases where just a field name is used, maybe something like:
/admin/lineitem/?flt_admin_eq={{request.args["id"]}}
/admin/lineitem/?flt_admin_ne={{request.args["id"]}}
/admin/lineitem/?flt_admin_gt={{request.args["id"]}}
/admin/lineitem/?flt_admin_lt={{request.args["id"]}}

Thoughts?

I see.. Current naming convention was not intended to be used outside of Flask-Admin.

While it might be OK to redo naming convention, I'm also thinking about exposing some kind of API to generate filter link based on the name and value.

I kind of figured we were using it outside of its original design :)

I think an api (something like url_for with filter awareness) would be nice. I also thinking having more expressive URLs would be nice, but understand it may not be worthwhile.

Closing this for now. As a workaround, you can override default filter by adding explicit filter to SQLa query.
