How to use jinja2schema with custom filter?

[whitelynx]

This should work:

from jinja2 import Environment
from jinja2schema import infer_from_ast, parse, to_json_schema

# Note: You can also use extensions by passing e.g.
# `extensions=['jinja2.ext.with_']` to the `Environment()` constructor.
environment = Environment()
environment.filters["my_filter"] = my_filter
print(infer_from_ast(parse(template, environment)))

How can we ignore all custom filters ?

[bpil]

Custom filters are rejected during the filter check process in visitors/expr.py in visit_filter(). You can force an unknown filter to be considered as returning a string by modifying the last step : Original code on line 529:

else:
        raise InvalidExpression(ast, 'unknown filter')

Replace with :

else:
        ctx.meet(Scalar(), ast)
        node_struct = Scalar.from_ast(ast.node, order_nr=config.ORDER_OBJECT.get_next())
        return_struct_cls = String

Thanks, I will check..

Just stumbled upon this. Would it be possible to add an optional argument to the parse method? A dict that contains filtername/(type|callback func) pairs which can be used for lookup?

Or at least an 'ignore_unknown_filters' option?
