Introduction
Create a simple Categories API that stores category tree to database and returns category parents, children and siblings by category id.
Requirements
Use Python 3 and Django Rest Framework. Use of any other third-party libraries is prohibited.
Categories Endpoint
Create POST /categories/ API endpoint. Endpoint should accept json body (see example Request), validate input data (see Request) and save categories to database (category name should be unique).
Example.
Request:
{
"name": "Category 1",
"children": [
{
"name": "Category 1.1",
"children": [
{
"name": "Category 1.1.1",
"children": [
{
"name": "Category 1.1.1.1"
},
{
"name": "Category 1.1.1.2"
},
{
"name": "Category 1.1.1.3"
}
]
},
{
"name": "Category 1.1.2",
"children": [
{
"name": "Category 1.1.2.1"
},
{
"name": "Category 1.1.2.2"
},
{
"name": "Category 1.1.2.3"
}
]
}
]
},
{
"name": "Category 1.2",
"children": [
{
"name": "Category 1.2.1"
},
{
"name": "Category 1.2.2",
"children": [
{
"name": "Category 1.2.2.1"
},
{
"name": "Category 1.2.2.2"
}
]
}
]
}
]
}Category Endpoint
Create GET /categories// API endpoint. Endpoint should retrieve category name, parents, children and siblings (see examples) by primary key () in json format.
Example 1.
GET /categories/2/
Response:
{
"id": 2,
"name": "Category 1.1",
"parents": [
{
"id": 1,
"name": "Category 1"
}
],
"children": [
{
"id": 3,
"name": "Category 1.1.1"
},
{
"id": 7,
"name": "Category 1.1.2"
}
],
"siblings": [
{
"id": 11,
"name": "Category 1.2"
}
]
}Example 2.
GET /categories/8/
Response:
{
"id": 8,
"name": "Category 1.1.2.1",
"parents": [
{
"id": 7,
"name": "Category 1.1.2"
},
{
"id": 2,
"name": "Category 1.1"
},
{
"id": 1,
"name": "Category 1"
}
],
"children": [],
"siblings": [
{
"id": 9,
"name": "Category 1.1.2.2"
},
{
"id": 10,
"name": "Category 1.1.2.3"
}
]
}
