How to ignore the dot attribute in render？ about jinjava

[jasmith-hs]

You aren't able to put a variable with the name foo.bar onto the context in jinja so you cannot evaluate {{ foo.bar }}. It will always try to evaluate bar as being an attribute of foo. If you stored contact as a map that had a key name, then calling {{ contact.name }} would get you jack

To add to this programming languages will enforce a set of allowed characters for variable names including Jinjava. In this case . is a reserved character.

You would want to do:

context.put("person", ImmutableMap.of("name", "jack"));
``

To add to what @mattcoley said above, I would recommend against inserting an immutable map if you plan to allow the code to update the value later as you would hit an unsupported operation exception if you tried to update the value eg {% set person.name = 'John' %} . Instead do context.put("person", Map.of("name", "jack"));
