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')
Notice the controller here is a string. This is a great way to specify controllers as you do not have to import anything into your web.py
file. All imports will be done in the backend. More on controllers later.
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)
]
It’s important here to recognize that we initialized the controller but only passed a reference to the method and did not actually call the method. This is so Masonite can pass parameters into the method when it executes the route.
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.
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 url’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.
Module Controllers
All controllers are located in app/http/controllers
but sometimes you may wish to put your controllers in different modules 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 uses our usual dot notation:
Get().route('/dashboard', 'users.DashboardController@show')
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
to 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 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.
