Masonite 2.2 to 2.3

Preface
Welcome to Masonite 2.3! In this guide we will walk you through how to upgrade your Masonite application from version 2.2 to version 2.3.
In this guide we will only be discussing the breaking changes and won't talk about how to refactor your application to use the awesome new features that 2.3 provides. For that information you can check the Whats New in 2.3 documentation to checkout the new features and how to refactor.
We'll walk through both Masonite upgrades and breaking packages as well
Masonite
Pip uninstall masonite-cli
Craft is now a part of Masonite core so you can uninstall the masonite-cli tool. You now no longer need to use that as a package.
This is a little weird but we'll get craft back when we install Masonite 2.3
1
$ pip uninstall masonite-cli
Copied!
Upgrade Your Masonite and CLI Version
Next, we can upgrade your Masonite version. Depending on your dependancy manager it will look something like this:
Change it from this:
1
masonite>=2.2,<2.3
Copied!
to
1
masonite>=2.3,<2.4
Copied!
Go ahead and install masonite now:
1
pip install "masonite>=2.3,<2.4"
Copied!
Change Server Response
Masonite changed the way the response is generated internally so you will need to modify how the response is retrieved internally. To do this you can go to your bootstrap/start.py file and scroll down to the bottom.
Change it from this:
1
return iter([bytes(container.make('Response'), 'utf-8')])
Copied!
to this:
1
return iter([container.make('Response')])
Copied!
This will allow Masonite to better handle responses. Instead of converting everything to a string like the first snippet we can now return bytes. This is useful for returning images and documents.
Package Requirements
Previously Masonite used several packages and required them by default to make setting everything up easier. This slows down package development because now any breaking upgrades for a package like Masonite Validation requires waiting for the the next major upgrade to make new breaking features and improve the package.
Now Masonite no longer requires these packages by default and requires you as the developer to handle the versioning of them. This allows for more rapid development of some of Masonite packages.
Masonite packages also now use SEMVER versioning. This is in the format of MAJOR.MINOR.PATCH. Here are the required versions you will need for Masonite 2.3:
masonite-validation>=3.0.0
masonite-scheduler>=3.0.0
These are the only packages that came with Masonite so you will need to now manage the dependencies on your own. It's much better this way.
Authentication has been completely refactored
Masonite now uses a concept called guards so you will need a quick crash course on guards. Guards are simply logic related to logging in, registering, and retrieving users. For example we may have a web guard which handles users from a web perspective. So registering, logging in and getting a user from a database and browser cookies.
We may also have another guard like api which handles users via a JWT token or logs in users against the API itself.
Guards are not very hard to understand and are actually unnoticable unless you need them.
In order for the guards to work properly you need to change your config/auth.py file to use the newer configuration settings.
You'll need to change your settings from this:
1
AUTH={
2
    'driver': env('AUTH_DRIVER', 'cookie'),
3
    'model': User,
4
}
Copied!
to this:
1
AUTH = {
2
    'defaults': {
3
        'guard': 'web'
4
    },
5
    'guards': {
6
        'web': {
7
            'driver': 'cookie',
8
            'model': User,
9
            'drivers': { # 'cookie', 'jwt'
10
                'jwt': {
11
                    'reauthentication': True,
12
                    'lifetime': '5 minutes'
13
                }
14
            }
15
        },
16
    }
17
}
Copied!
Add The Authentication Provider
To manage the guards (and register new guards) there is the new AuthenticationProvider that needs to be added to your providers list.
1
from masonite.providers import AuthenticationProvider
2
​
3
PROVIDERS = [
4
    # Framework Providers
5
    # ...
6
    AuthenticationProvider,
7
​
8
    # Third Party Providers
9
    #...
10
]

Removed The Sass Provider
Masonite no longer supports SASS and LESS compiling. Masonite now uses webpack and NPM to compile assets. You will need to now reference the Compiling Assets documentation.
You will need to remove the SassProvider completely from the providers list in config/providers.py. As well as remove the SassProvider import from on top of the file.
You can also completely remove the configuration settings in your config/storage.py file:
1
SASSFILES = {
2
    'importFrom': [
3
        'storage/static'
4
    ],
5
    'includePaths': [
6
        'storage/static/sass'
7
    ],
8
    'compileTo': 'storage/compiled'
9
}
Copied!
Be sure to reference the Compiling Assets documentation to know how to use the new NPM features.
Removed The Ability For The Container To Hold Modules
The container can no longer hold modules. Modules now have to be imported in the class you require them. For example you can't bind a module like this:
1
from config import auth
2
​
3
app.bind('AuthConfig', auth)
Copied!
and then make it somewhere else:
1
class ClassA:
2
​
3
    def __init__(self, container: Container):
4
        self.auth = container.make('AuthConfig')
Copied!
This will throw a StrictContainerError error. Now you have to import it so will have to do something like this using the example above:
1
from config import auth
2
​
3
class ClassA:
4
​
5
    def __init__(self, container: Container):
6
        self.auth = auth
Copied!
Remove Modules from Container
Now that we can no longer bind modules to the container we need to make some changes to the wsgi.py file because we did that here.
Around line 16 you will see this:
1
container.bind('Application', application)
Copied!
Just completely remove that line. Its no longer needed.
Also around line 19 you will see this line:
1
container.bind('ProvidersConfig', providers)
Copied!
You can completely remove that as well.
Lastly, around line 31 you can change this line:
1
for provider in container.make('ProvidersConfig').PROVIDERS:
Copied!
to this:
1
for provider in providers.PROVIDERS:
Copied!
Changed How Query Strings Are Parsed
It's unlikely this effects you and query string parsing didn't change much but if you relied on query strings like this:
/?filter[name]=Joe&filter[user]=bob&[email protected]
Or html elements like this:
1
<input name="options[name]" value="Joe">
2
<input name="options[user]" value="bob">
Copied!
then query strings will now parse to:
1
{
2
    "email": "[email protected]",
3
    "options": {
4
        "name": "Joe",
5
        "user": "bob"
6
    }
7
}
Copied!
You'll have to update any code that uses this. If you are not using this then don't worry you can ignore it.
Scheduler Namespace
Not many breaking changes were done to the scheduler but there are alot of new features. Head over to the Whats New in Masonite 2.3 section to read more.
We did change the namespace from scheduler to masonite.scheduler. So you will need to refactor your imports if you are using the scheduler.
Conclusion
You should be all good now! Try running your tests or running craft serve and browsing your site and see if there are any issues you can find. If you ran into a problem during upgrading that is not found in this guide then be sure to reach out so we can get the guide upgraded.
