flatten_errors(cfg, res, levels=None, results=None)
cfg
is the ConfigObj instance being checked, res
is the results dictionary returned by validate
.
(This is a recursive function, so you shouldn't use the levels
or results
arguments - they are used by the function.)
Returns a list of keys that failed. Each member of the list is a tuple:
([list of sections...], key, result)
If validate
was called with preserve_errors=False
(the default) then result
will always be False
.
list of sections is a flattened list of sections that the key was found in.
If the section was missing (or a section was expected and a scalar provided - or vice-versa) then key will be None
.
If the value (or section) was missing then result
will be False
.
If validate
was called with preserve_errors=True
and a value was present, but failed the check, then result
will be the exception object returned. You can use this as a string that describes the failure.
For example The value "3" is of the wrong type.
An example function that will turn a nested dictionary of results (as returned by ConfigObj.validate
) into a flat list.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
