This attaches to the live node. Expressions run against that node's actual code and data, so start with read-only inspection.<\/p>\n
C = z:c(garden).\nz_context:site(C).\n<\/code><\/pre>\n
Expect the site name garden<\/code>. A fresh site context is not automatically an administrator context. Use an authenticated request context or deliberate, local-only elevation when testing mutations.<\/p>\n
Leave the remote shell with Ctrl-C twice<\/strong>. Do not call q().<\/code> or halt().<\/code> to detach: they can stop the shared node.<\/p>\n
If connection fails, check the target node name, Erlang distribution setup, and cookie configuration. See Work with a site context<\/a> and Inspect content from the Erlang shell<\/a>.<\/p>\n

The named resource must exist on that site; undefined<\/code> can mean the chosen name is absent. Use the generated site's real resource names rather than assuming every skeleton creates identical content.<\/p>\n
Inspect individual properties first instead of dumping an entire resource containing private fields. Use models for normal content access, and understand the ACL context before interpreting missing results.<\/p>\n
For a portable representation, inspect model#rsc_export<\/code><\/a>. For changes, use model#rsc<\/code><\/a> and model#edge<\/code><\/a>, then check the public result separately.
