django-http-exceptions 1.0.0

django raisable http exceptions

## What is *django_http_exceptions*?

It is raisable exceptions for your django views.

## What is it good for?

It makes this

````py
def some_function():
raise SomeError

def view(request):
try:
response = some_function()
except SomeError:
response = HttpResponse(status=403)
return response
````
into this
````py
from django_http_exceptions import HTTPExceptions
def some_function():
raise HTTPExcetions.FORBIDDEN # HTTPExceptions.from_status(403)

def view(request):
return some_function()

````

meaning that is saves you from boilerplate code.

It also allows you to hook default views to **all possible http response codes**, meaning that you can use more than the 5-6 django provided error handlers.

## How to use it?

Just two middlewares, lower the better, and you are done.

````python
MIDDLEWARE = [
...,
'django_http_exceptions.middleware.ExceptionHandlerMiddleware',
'django_http_exceptions.middleware.ThreadLocalRequestMiddleware',
...
]
````

And that is it, you are ready to raise your http exceptions.


## What else?

#### `HTTPExceptions`
Base class that provides all the exceptions to be raised.

#### `HTTPExceptions.from_status(status)`
In case you don't want to write
`HTTPExceptions.REQUEST_HEADER_FIELDS_TOO_LARGE`
You can just write
`HTTPExceptions.from_status(431)`

#### `HTTPExceptions.BASE_EXCEPTON`
The base exception for all http exception

####`HTTPExceptions.BASE_EXCEPTION.with_response(response)`
This is the method for rasing exceptions with a response. You can put any response in this method while raising your
error.

Let's say you have a view named `index`, then this example would return what `index` function would return, but with
status code `410`
`HTTPExceptions.GONE.with_response(index(request))`

#### `HTTPExceptions.BASE_EXCEPTION.register_default_view(view)`
`view` is a function that takes only one argument, `request` when you register a default view to an error class with
`HTTPExceptions.NOT_FOUND.register_defaul_view(view)` when `HTTPExceptions.GONE` is raised it returns the view function,
but again, with `404` status code. If the error has been raised with `.with_response`, that is used instead.

#### `get_current_request`

This function gets you the current request anywhere in your django application, making it easier for your dynamic error
responses to be created, like in the `HTTPExceptions.GONE.with_response(index(request))` example.

#### `ExceptionHandlerMiddleware`

Just there for to exception handling to work.

#### `ThreadLocalRequestMiddleware`

Just there for to `get_current_request` to work.
