README
A Python library to make writing applications with FaunaDB easier.
Includes GraphQL and generic ABAC auth workflow integrations.
## Key Features
- DRY (Don't Repeat Yourself) code to help you create multiple collections, indexes, roles, and user-defined functions
quickly. This helps you create more functionality with less code.
- Mix and match authorization workflows (Group and user based)
- Group level permissions
- Create a GraphQL endpoint and a schema validating ORM with the same code.
- Authentication collections, indexes, user-defined functions, and roles included.
- Generic CRUD user-defined functions included
- Create a REST API to integrate Fauna and Non-Fauna related tasks
- Schema validation based on the [Valley](https://github.com/capless/valley) library.

### Getting Started
### Installation
```pip install pfunk```
### Setup the Connection
#### Using Environment Variables (Preferred Method)
If you can easily set environment variables just set the ```FAUNA_SECRET``` environment variable to your key.
### Define your Collections (collections.py)
For an example project let's create a project management app.
```python
from pfunk import (Collection, StringField, ReferenceField, DateField,
Project, Enum, EnumField, IntegerField, FloatField,
SlugField)
from pfunk.contrib.auth.collections import User, Group
from pfunk.contrib.auth.resources import GenericGroupBasedRole, GenericUserBasedRole
STATUS = Enum(name='ProductStatus', choices=['unstarted', 'started', 'completed', 'delivered'])
class AbstractGroupCollection(Collection):
"""
Abstract Collection very similar to abstract models in Django.
The main difference is you don't have to add abstract=True in the Meta class.
"""
# Here we are defining the roles that should be
# created for this collection (by proxy this role will be applied
# to its subclasses. We could however change the list of roles below.
collection_roles = [GenericGroupBasedRole]
title = StringField(required=True)
group = ReferenceField(Group, required=True)
def __unicode__(self):
return self.title
class Product(AbstractGroupCollection):
slug = SlugField(required=True)
description = StringField()
due_date = DateField(required=False)
class Meta:
"""
Add unique together index to ensure that the same slug is not used
for more than one product that belongs to a group. Similar to the
Github's repo naming convention ex. https://github.com/capless/pfunk.
In that example 'capless' is the group slug and 'pfunk' is the
product's slug
"""
unique_together = ('slug', 'group')
class Sprint(AbstractGroupCollection):
product = ReferenceField(Product, required=True)
start_date = DateField(required=True)
end_date = DateField(required=True)
class Story(AbstractGroupCollection):
description = StringField()
points = IntegerField()
product = ReferenceField(Product, required=True)
sprint = ReferenceField(Sprint, required=False)
status = EnumField(STATUS)
# Create a Project
project = Project()
# Add Collections to the Project
project.add_resources([User, Group, Product, Story, Sprint])
```
### Auth Workflows
In the example above, the ```collection_roles``` list on the ```Collection``` classes attaches generic roles to the
collection. Currently, you can choose a **group based** workflow, **user based**, or a **mix** of the two.
#### User Based Role
This role allows you to create, read, write, and delete documents that you haveyou are the owner of. The `user` field determines if you are the owner.
#### Group Based Role
This role allows you to create, read, write, and delete documents if both of the following conditions are true:
1. You belong to the group that owns the document
2. You have the create permission to perform the action (`create`, `read`, `write`, and `delete`)
### Publish
```python
project.publish()
```
### Create Group and User
Both of the code samples below will create a new user, group, and users_groups (many-to-many relationship through collection) record.
```python
from pfunk.contrib.auth.collections import Group, User
group = Group.create(name='base', slug='base')
# Example 2: You could also create a user with the following code
user = User.create(username='notthegoat', first_name='Lebron', last_name='James',
email='[email protected]', account_status='ACTIVE', groups=[group],
_credentials='hewillneverbethegoat')
```
### Give User New Permissions
```python
# User instance from above (username: notthegoat)
user.add_permissions(group, ['create', 'read', 'write', 'delete'])
```
### Login
```python
from pfunk.contrib.auth.collections import User
#The login classmethod returns the authenticated token if the credentials are correct.
token = User.login('goat23', 'cruelpass')
```
### Save Some Data
Let's use the Video collection, and the authenticated token we created above to save some data.
```python
# Use the token from above so the current users permissions are used.
product = Product.create(
title='PFunk Project',
slug='pfunk',
description='Some example project for test Pfunk',
group=group,
_token=token #The token gained in the previous step. If you do not specify a token here it defaults to the key used in the FAUNA_SECRET env.
)
```
### Query your Data
Let's get the video you just created.
```python
product = Product.get('the-key-for-the-previous-video', _token=token)
```
Let's query for all videos using the server key.
```python
products = Products.all()
```
Let's query for all videos that the logged in user has access to.
```python
products = Products.all(_token=token)
```
### Delete a Record
Let's delete the record from above.
```python
product.delete()
```
