Routing

Introduction

Masonite Routing is an extremely simple but powerful routing system that at a minimum takes a url and a controller. Masonite will take this route and match it against the requested route and execute the controller on a match.

All routes are created inside routes/web.py and are contained in a ROUTES constant. All routes consist of either a Get() route or a Post() route. At the bare minimum, a route will look like:

Get().route('/url/here', 'WelcomeController@show')

Most of your routes will consist of a structure like this. All URI’s should have a preceding /. Routes that should only be executed on Post requests (like a form submission) will look very similar:

Post().route('/url/here', 'WelcomeController@store')

If you wish to not use string controllers and wish to instead import your controller then you can do so by specifying the controller as well as well as only passing a reference to the method. This will look like:

...
from app.http.controllers.DashboardController import DashboardController


ROUTES = [
    Get().route('/url/here', DashboardController.show)
]

Route Options

There are a few methods you can use to enhance your routes. Masonite typically uses a setters approach to building instead of a parameter approach so to add functionality, we can simply attach more methods.

HTTP Verbs

There are several HTTP verbs you can use for routes:

from masonite.routes import Get, Post, Put, Patch, Delete

Get().route(...)
Post().route(...)
Put().route(...)
Patch().route(...)
Delete().route(...)

HTTP Helpers

If the syntax is a bit cumbersome, you just want to make it shorter or you like using shorthand helper functions, then you can also use these:

from masonite.helpers.routes import get, post, put, patch, delete

ROUTES = [
    get('/url/here', 'Controller@method'),
    post('/url/here', 'Controller@method'),
    put('/url/here', 'Controller@method'),
    patch('/url/here', 'Controller@method'),
    delete('/url/here', 'Controller@method'),
]

These return instances of their respective classes so you can append on to them:

get('/url/here', 'Controller@method').middleware(...),

Most developers choose to use these instead of the classes.

Route Groups

Sometimes routes can be very similiar such as having many dashboard or profile routes:

ROUTES = [
    Get().route('/home', ...),
    Get().route('/dashboard', ...),
    Get().route('/dashboard/user', ...),
    Get().route('/dashboard/user/@id', ...),
    Get().route('/dashboard/friends', ...),
    ...
]

These routes can be grouped using the group helper:

from masonite.helpers.routes import group

ROUTES = [
    Get().route('/home', 'DashboardController@show'),
    group('/dashboard', [
        Get().route('/user', ...)
        Get().route('/user/@id', ...)
        Get().route('/user/friends', ...)
    ])
]

Notice that this is the same as above and can help organize and group routes. This feature will also be expanded on in future releases of Masonite.

Named Routes

We can name our routes so we can utilize these names later when or if we choose to redirect to them. We can specify a route name like so:

Get().route('/dashboard', 'DashboardController@show').name('dashboard')

It is good convention to name your routes since route URI's can change but the name should always stay the same.

Route Middleware

Middleware is a great way to execute classes, tasks or actions either before or after requests. We can specify middleware specific to a route after we have registered it in our config/middleware.py file but we can go more in detail in the middleware documentation. To add route middleware we can use the middleware method like so:

Get().route('/dashboard', 'DashboardController@show').middleware('auth', 'anothermiddleware')

This middleware will execute either before or after the route is executed depending on the middleware.

Deeper Module Controllers

All controllers are located in app/http/controllers but sometimes you may wish to put your controllers in different modules deeper inside the controllers directory. For example, you may wish to put all your product controllers in app/http/controllers/products or all of your dashboard controllers in app/http/controllers/users. In order to access these controllers in your routes we can simply specify the controller using our usual dot notation:

Get().route('/dashboard', 'users.DashboardController@show')

Global Controllers

Controllers are defaulted to the app/http/controllers directory but you may wish to completely change the directory for a certain route. We can use a forward slash in the beginning of the controller namespace:

Get().route('/dashboard', '/thirdparty.package.users.DashboardController@show')

This can enable us to use controllers in third party packages.

Route Parameters

Very often you’ll need to specify parameters in your route in order to retrieve information from your URI. These parameters could be an id for the use in retrieving a certain model. Specifying route parameters in Masonite is very easy and simply looks like:

Get().route('/dashboard/@id', 'Controller@show')

That’s it. This will create a dictionary inside the Request object which can be found inside our controllers.

In order to retrieve our parameters from the request we can use the param method on the Request object like so:

def show(self, Request):
    Request.param('id')

Route Parameter Options

Sometimes you will want to make sure that the route parameter is of a certain type. For example you may want to match a URI like /dashboard/1 but not /dashboard/joseph. In order to do this we simply need to pass a type to our parameter. If we do not specify a type then our parameter will default to matching all alphanumeric and underscore characters.

Get().route('/dashboard/@id:int', 'Controller@show')

This will match all integers but not strings. So for example it will match /dashboard/10283 and not /dashboard/joseph

If we want to match all strings but not integers we can pass:

Get().route('/dashboard/@id:string', 'Controller@show')

This will match /dashboard/joseph and not /dashboard/128372. Currently only the integer and string types are supported.

Subdomain Routing

You may wish to only render routes if they are on a specific subdomain. For example you may want example.com/dashboard to route to a different controller than joseph.example.com/dashboard. To do this we can use the .domain() method on our routes like so:

Get().domain('joseph').route('/dashboard', 'Controller@show')

This route will match to joseph.example.com/dashboard but not to example.com/dashboard or test.example.com/dashboard.

It may be much more common to match to any subdomain. For this we can pass in an asterisk instead.

Get().domain('*').route('/dashboard', 'Controller@show')

This will match all subdomains such as test.example.com/dashboard, joseph.example.com/dashboard but not example.com/dashboard.

If a match is found, it will also add a subdomain parameter to the Request class. We can retrieve the current subdomain like so:

def show(self, Request):
    print(Request.param('subdomain'))
