API

Base endpoints

  1. /api/v1/likes/list/ - List API View to return all likes for authenticated user.

    You can set serializer for each model in LIKES_MODELS setting to use it for content object serialization, otherwise, you will get an id of content object.

    For example:

    LIKE_MODELS = {
        "article.Article": {
            'serializer': 'article.api.serializers.ArticleSerializer'
        },
    }
    

    Use GET parameter search to filter by a content type’s model: /api/v1/likes/list/?search=article

  2. /api/v1/likes/count/ - API View to return count of likes for authenticated user.

  3. /api/v1/likes/is/ - API View to check is given elements are liked by authenticated user. As result, you will get a list of ids.

    Possible payload:

    {
        "content_type": 1,
        "ids": [1,2,3]
    }
    

    Possible result:

    {
        "ids": [1,3]
    }
    
  4. /api/v1/likes/toggle/ - API View to like-unlike a given object by authenticated user.

    Possible payload:

    {
        "content_type": 1,
        "id": 1
    }
