A nice way to use Redis in your Flask app.
## Configuration
Start by installing the extension with `pip install flask-redis`.
Once that's done, configure it within your Flask config.
Set the URL of your Redis instance like this:
```python
REDIS_URL = "redis://:password@localhost:6379/0"
```
If you wanna connect to a Unix socket,
you can specify it like `"unix://:password@/path/to/socket.sock?db=0"`.
## Usage
### Setup
To add a Redis client to your application:
```python
from flask import Flask
from flask_redis import FlaskRedis
app = Flask(__name__)
redis_client = FlaskRedis(app)
```
or if you prefer, you can do it the other way around:
```python
redis_client = FlaskRedis(app)
def create_app():
app = Flask(__name__)
redis_client.init_app(app)
return app
```
### Accessing Redis
The redis client you created above from `FlaskRedis` acts just like a regular `Redis` instance from the [`redis-py`](https://github.com/andymccurdy/redis-py) library:
```python
from my_app import redis_client
@app.route('/')
def index():
return redis_client.get('potato')
```
For detailed instructions on what methods you can use on the client,
as well as how you can use advanced features
such as Lua scripting, pipelines, and callbacks,
please check the
[redis-py documentation](https://redis-py.readthedocs.io/en/latest/).
**Pro-tip:** The [redis-py](https://github.com/andymccurdy/redis-py)
package uses the `redis` namespace, so it's nicer to name your Redis object something like `redis_client` instead of just `redis`.
## Extra features in flask-redis
### Custom providers
Instead of the default `Redis` client from `redis-py`,
you can provide your own.
This can be useful to replace it with [mockredis](https://github.com/locationlabs/mockredis) for testing:
```python
from flask import Flask
from flask_redis import FlaskRedis
from mockredis import MockRedis
def create_app():
app = Flask(__name__)
if app.testing:
redis_store = FlaskRedis.from_custom_provider(MockRedis)
else:
redis_store = FlaskRedis()
redis_store.init_app(app)
return app
```
## Contributing
1. Check for open issues or open a fresh issue to start a discussion
2. Fork [the repository](https://github.com/underyx/flask-redis) on GitHub.
3. Send a pull request with your code!
Merging will require a test which shows that the bug was fixed,
or that the feature works as expected.
Feel free to open a draft pull request though without such a test
and ask for help with writing it if you're not sure how to.
As [Bence](https://underyx.me) (the only maintainer) works full-time,
please allow some time before your issue or pull request is handled.
## Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
## 0.4.0 (2019-05-29)
- Reorganized the module and rewrote everything other than the library code, mainly packaging and CI. There are no user-facing changes in behavior.
## 0.3.0 (2016-07-18)
- **Backwards incompatible:** The `FlaskRedis.init_app` method no
longer takes a `strict` parameter. Pass this flag when creating your
`FlaskRedis` instance, instead.
- **Backwards incompatible:** The extension will now be registered
under the (lowercased) config prefix of the instance. The default
config prefix is `'REDIS'`, so unless you change that, you can still
access the extension via `app.extensions['redis']` as before.
- **Backwards incompatible:** The default class has been changed to
`redis.StrictRedis`. You can switch back to the old `redis.Redis`
class by specifying `strict=False` in the `FlaskRedis` kwargs.
- You can now pass all supported `Redis` keyword arguments (such as
`decode_responses`) to `FlaskRedis` and they will be correctly
passed over to the `redis-py` instance. Thanks, @giyyapan\!
- Usage like `redis_store['key'] = value`, `redis_store['key']`, and
`del redis_store['key']` is now supported. Thanks, @ariscn\!
## 0.2.0 (2015-04-15)
- Made 0.1.0's deprecation warned changes final
## 0.1.0 (2015-04-15)
- **Deprecation:** Renamed `flask_redis.Redis` to
`flask_redis.FlaskRedis`. Using the old name still works, but emits
a deprecation warning, as it will be removed from the next version
- **Deprecation:** Setting a `REDIS_DATABASE` (or equivalent) now
emits a deprecation warning as it will be removed in the version in
favor of including the database number in `REDIS_URL` (or
equivalent)
- Added a `FlaskRedis.from_custom_provider(provider)` class method for
using any redis provider class that supports instantiation with a
`from_url` class method
- Added a `strict` parameter to `FlaskRedis` which expects a boolean
value and allows choosing between using `redis.StrictRedis` and
`redis.Redis` as the defualt provider.
- Made `FlaskRedis` register as a Flask extension through Flask's
extension API
- Rewrote test suite in py.test
- Got rid of the hacky attribute copying mechanism in favor of using
the `__getattr__` magic method to pass calls to the underlying
client
## 0.0.6 (2014-04-09)
- Improved Python 3 Support (Thanks underyx\!).
- Improved test cases.
- Improved configuration.
- Fixed up documentation.
- Removed un-used imports (Thanks underyx and lyschoening\!).
## 0.0.5 (2014-02-17)
- Improved suppot for the config prefix.
## 0.0.4 (2014-02-17)
- Added support for config_prefix, allowing multiple DBs.
## 0.0.3 (2013-07-06)
- Added TravisCI Testing for Flask 0.9/0.10.
- Added Badges to README.
## 0.0.2 (2013-07-06)
- Implemented a very simple test.
- Fixed some documentation issues.
- Included requirements.txt for testing.
- Included task file including some basic methods for tests.
## 0.0.1 (2013-07-05)
- Conception
- Initial Commit of Package to GitHub.
