jinja2.sandbox.ImmutableSandboxedEnvironment

class documentation

class ImmutableSandboxedEnvironment(SandboxedEnvironment):

Works exactly like the regular SandboxedEnvironment but does not permit modifications on the builtin mutable objects list, set, and dict by using the modifies_known_mutable function.

Method is_safe_attribute No summary

Inherited from SandboxedEnvironment:

Method	`call_binop`	For intercepted binary operator calls (`intercepted_binops`) this function is executed instead of the builtin operator. This can be used to fine tune the behavior of certain operators.
Method	`call_unop`	For intercepted unary operator calls (`intercepted_unops`) this function is executed instead of the builtin operator. This can be used to fine tune the behavior of certain operators.
Method	`is_safe_callable`	Check if an object is safely callable. By default callables are considered safe unless decorated with `unsafe`.
Class Variable	`default_binop_table`	Undocumented
Class Variable	`default_unop_table`	Undocumented

Class Variable	`intercepted_unops`	Undocumented
Method	`__init__`	Undocumented
Method	`call`	Call an object from sandboxed code.
Method	`format_string`	If a format call is detected, then this is routed through this method so that our safety sandbox can be used for it.
Method	`getattr`	Subscribe an object from sandboxed code and prefer the attribute. The attribute passed must be a bytestring.
Method	`getitem`	Subscribe an object from sandboxed code.
Method	`unsafe_undefined`	Return an undefined object for unsafe attributes.

def is_safe_attribute(self, obj, attr, value):

overrides jinja2.sandbox.SandboxedEnvironment.is_safe_attribute

The sandboxed environment will call this method to check if the attribute of an object is safe to access. Per default all attributes starting with an underscore are considered private as well as the special attributes of internal python objects as returned by the is_internal_attribute function.

Parameters

attr:`str`	Undocumented
value:`t.Any`	Undocumented
