Examples
===

Example is the best and fastest way to start.

## 1.Limit directly

You can call the limiter decorator directly to wrap your view function like that.
**myapp/views.py**

from django.shortcuts import HttpResponse
from apilimiter.decorators import limiter

@limiter(key='',times=5)
def index(request):
return HttpResponse("decorators test")

If you view this api more than 5 times in a day, it will return the 403 page.


## 2.Limit with a key

* key - The **key** parameter should be part of attribute or sub-attribute for the **request**.

If you want to limit the IP address in request(*request.META['REMOTE_ADDR']*), write like this.

**myapp/views.py**

from django.shortcuts import HttpResponse
from apilimiter.decorators import limiter

@limiter(key='META['REMOTE_ADDR']',times=5, redirect='/myapp/wrong')
def index(request):
return HttpResponse("decorators test")

### Limit by user

What I want to limit first! But if you want to do this, you should call some authentication first.
Let's take an example of **django.contrib.auth**.

**myapp/views.py**

from django.shortcuts import HttpResponse
from apilimiter.decorators import limiter
from django.contrib.auth.decorators import login_required

@login_required(login_url="/admin/login/")
@limiter(key='user.id',times=5, redirect='/myapp/wrong')
def index(request):
return HttpResponse("decorators test")



## 3.Limit with a redirect

Also you can define ** redirect='/...' ** to return a special url to replace the 403 page.

**myapp/views.py**

from django.shortcuts import HttpResponse
from apilimiter.decorators import limiter

@limiter(key='',times=5, redirect='/myapp/wrong')
def index(request):
return HttpResponse("decorators test")

**myapp/urls.py**

from django.conf.urls import url, include
from myapp import views

urlpatterns = [
url(r'^$', views.index),
url(r'^wrong$', views.wrong),
]

### **redirect** also can be a view

**myapp/views.py**

@limiter(key='',times=5, redirect=wrong)
def index(request):
return HttpResponse("decorators test")

def wrong(request):
return HttpResponse("You can view the page any more!")


## 4.Limit with rate

You can control the rate with define **rate = 24 \* 60 \* 60** (s)
Here's the example which limit the index view 30 times per minute.

@limiter(key='',times=30, rate=60)
def index(request):
return HttpResponse("decorators test")


## 5.Limit with Mixin

from django.views.generic import View
from apilimiter.mixin import LimiterMixin
from django.shortcuts import HttpResponse

class MyView(LimiterMixin, View):
times = 5
key = 'user.id'
redirect = ''
rate = 60

def get(self, request):
return HttpResponse('Mixin test')
