Overview
Module that provides rails and active support compatibility.
Defined Under Namespace
Classes: Encoder
Class Method Summary collapse
-
.deoptimize(*classes) ⇒ Object
Turn off Oj rails optimization on the specified classes.
-
.encode(obj, opts = nil) ⇒ Object
Encode obj as a JSON String.
-
.mimic_JSON ⇒ Object
Sets the JSON method to use Oj similar to Oj.mimic_JSON except with the ActiveSupport monkey patches instead of the json gem monkey patches.
-
.optimize(*classes) ⇒ Object
Use Oj rails optimized routines to encode the specified classes.
-
.optimized?(clas) ⇒ Boolean
Returns true if the specified Class is being optimized.
-
.set_decoder ⇒ Object
Sets the JSON.parse function to be the Oj::parse function which is json gem compatible.
-
.set_encoder ⇒ Object
Sets the ActiveSupport.encoder to Oj::Rails::Encoder and wraps some of the formatting globals used by ActiveSupport to allow the use of those globals in the Oj::Rails optimizations.

.optimize(*classes) ⇒ Object
Use Oj rails optimized routines to encode the specified classes. This ignores the as_json() method on the class and uses an internal encoding instead. Passing in no classes indicates all should use the optimized version of encoding for all previously optimized classes. Passing in the Object class set a global switch that will then use the optimized behavior for all classes.
