An Objective Knowledge Node Student is a link between an Objective Student and the Knowledge Nodes that have to be mastered for this Objective. It is created automatically when the Objective Student is created.


===Object resources===
^ Property     ^ Type      ^ Description         ^
| id | Integer | identifier for the database of Domoscio's API |
| threshold | Float | Between -4 and +4, represents the level of mastery the learner has to reach on that concept for this objective |
| validated | Boolean | true if the mastery of the KnowledgeNodeStudent is above the threshold |
| ability_reached | Float | Score you expect your user to have to validate the objective |
| objective_knowledge_node_id| Integer | identifier of the ObjectiveKnowledgeNode associated |
| knowledge_node_student_id | Integer | identifier of the KnowledgeNodeStudent associated |
| student_id | Integer | identifier of the Student associated |
| objective_id | Integer | identifier of the Objective associated |
| knowledge_node_id | Integer | identifier of the KnowledgeNode associated |
| objective_student_id | Integer | identifier of the ObjectiveStudent associated |
| memorize | Boolean | Does this concept in this objective has to be memorized? |
| deadline | Date | Does it have to be memorized for a specific deadline? |


===Fetch (GET)===

^ Method | GET|
^ URL | /objective_knowledge_node_students/{objective_knowledge_node_student_id} |

If no objective_knowledge_node_student_id is provided it will fetch all the Objective Knowledge Node Student for your instance.\\
If you do not know the objective_knowledge_node_student_id, you can filter the results by adding one of the following parameters :
- objective_id  \\
- student_id or uid  \\
- knowledge_node_id or uid  \\
- objective_student_id  \\
 and send the following request:

<code>
{
	"student_id": 1980
}
</code>
