# Django NoSQL user document storage
Django app that provides a simple REST API for storing and querying JSON documents.
Designed specially for cases where model schema is too variable or where the frontend is in charge of the schema of the stored data (backend as a service).
Notice that the word "document" and "object" are used interchangeably in this readme.
## Features
- Storing, querying, deleting schemaless JSON documents.
- Permission system that allows users define who can access their own documents.
- Query objects by their contents.
- Allow anonymous access to specific documents.
- REST API
# Package requirements
- django-filter
- django-guardian
- djangorestframework
- djangorestframework-guardian
# Installing
- Add the following apps in your settings.py:
```python
INSTALLED_APPS = (
...
"rest_framework",
"django_filters",
"guardian",
"nosql_objects",
...
)
AUTHENTICATION_BACKENDS = (
...
'django.contrib.auth.backends.ModelBackend',
'guardian.backends.ObjectPermissionBackend',
...
)
```
- Add the following routes in urls.py:
```python
urlpatterns = [
...
path('api/', include('nosql_objects.urls')),
...
]
```
- Execute migrations to add models to database.
```python
python manage.py migrate
```
# Object classes
Object classes define the types of objects that can be created in your application.
These types are analogous to models in Django and tables in a database, and their main purpose is to delimit the schema of your objects when querying.
The declaration of this classes can be done trough the admin portal of Django.
# Authentication
The examples below aren't showing any authentication code, but is required you add one like rest_framework_simplejwt.
# Creating new objects
Authorized users can create new objects like this:
```bash
curl -X POST -H "Content-Type: application/json" -d {{'{"object_class":"myClass", "data":{myInfo:"value"} }'}} {{http://yourdomain.com/api/objects/}}
```
# Querying
Clients can only query objects they read permission assigned.
The following query will list all objects visible by the user:
```bash
curl http://yourdomain.com/api/objects/
```
## Filter by class
Retriving objects on a class can be done by appending the class name in the query parameters:
```bash
curl http://yourdomain.com/api/objects/?object_class=my_class_name
```
Or with the unique ID of the class:
```bash
curl http://yourdomain.com/api/objects/?object_class=2
```
## Filter by object contents
Objects can be filtered by their content using the same Django syntax used for JSON fields, but passed as an object whose properties will be transformed into Django filters. For example the following code will bring all objects that have a property "myInfo" with a value of "test_value":
```bash
curl -H "Content-Type: application/json" -d {{'{"query":{"myInfo":"test_value"} }'}} {{http://yourdomain.com/api/objects/1/perms/}}
```
The querying filters can be appended with the following JSON filters to change behaviour:
|Name | Description | Example
| --- | --- | --- |
|__isnull|Checks if the value of the property is null| "propName__isnull":false
|__icontains|Case-insensitive containment test|"propName__icontains":"hello"
|__endswith|Case-sensitive ends-with.|"propName__endswith":"world"
|__iendswith|Case-insensitive ends-with.|"propName__iendswith":"World"
|__iexact|Case-insensitive exact match.|"propName__iexact":"hello world"
|__regex|Case-sensitive regular expression match|"propName__regex":false
|__iregex|Case-insensitive regular expression match|"propName__iregex":false
|__startswith|Case-sensitive starts-with|"propName__startswith":"Hello "
|__istartswith|Case-insensitive starts-with|"propName__istartswith":"hel"
|__lt|Number is less than|"propName__lt":4
|__lte|Number is less than or equal|"propName__lte":5
|__gt|Number is grater than|"propName__gt":4
|__gte|Number is greater than or equal|"propName__gte":5
Property queries can be nested by chaining the properties with double underscore before any filters, like this:
```json
{
"prop_example__isnull": false,
"prop_example__child_prop__endswith": " title",
}
```
Detailed info, caveats of the query system and some additional DB specific filters can be found [Django's documentation](https://docs.djangoproject.com/en/4.1/topics/db/queries/#querying-jsonfield).
*Warning*: Don't name properties of your documents with the same names as the filters, behavior is not documented yet.
## Pagination
Pagination is used to limit the amount of results returned in querying requests.
All the results contain the following structure:
```json
{
"count": 5,
"next": "https://api.example.org/accounts/?limit=100&offset=500",
"previous": "https://api.example.org/accounts/?limit=100&offset=300",
"results": [
{
"object_class": "scores",
"created_by": 1,
"updated_by": 1,
"created_at": "...",
"updated_at": "...",
"version": 1,
"data": {
"level1": 350
}
}
]
}
```
# Permissions
Each object contains its own list of permissions associated with it. Only users with the 'change' permission can change the permission list of an object.
The basic is the list of permissions `view_object`, `change_object` and `delete_object`. These are the same declared by Django, but custom permissions will be accepted too. Accessing the permissions endpoint is done using the ID of an existing object, like this:
```bash
curl -X POST -H "Content-Type: application/json" -d {{'{"view_object":{"users":["userB"]} }'}} {{http://yourdomain.com/api/objects/1/perms/}}
```
The permission endpoint **always** adds the permissions passed, unless the property `clear` is passed as true, then any existing permission is deleted before adding the new ones.
The endpoint expects a json with the list of permissions with the users, groups or anonymous user assigned (named 'AnonymousUser') to each, like this:
```json
{
"clear": true,
"view_object": {
"users": [
"userA",
"userB",
"AnonymousUser"
]
},
"change_object": {
"users": [
"userB"
]
},
"delete_object": {
"groups": [
"admin_group"
]
}
}
```
Notice that the anonymous user can only be assigned the permission of view, an existing user is required for any other type of permission.
