Path ValidationΒΆ
Some plugins specify a path within the source data. A path is simply an array of keys to be traversed within the source tree. The following options are added by this trait:
- path
- The array of keys used to specify the path in the source data
- current_value
- The optional current value in the source path. Used to ensure that the specified value exists in the source before manipulating it. This must be specified to enable path validation.
- value_path
- An optional path to be used instead of the normal
path
for validating thecurrent_value
. Used when changing the value inpath
but testingcurrent_value
in a differentvalue_path
.
