Advanced Usage

You can change urls

Defaults

• Login page - /login
• Register page - /register
• Logout url - /logout
• Home page - /

Write your urls before calling init() method at Auth class:

...

auth = Auth(app=app, db=db, login_url='/mylogin',
            register_url='/myreg', logout_url='/myexit',
            home_page='/')
auth.init()
...

You can set your own template config!

You can change:

• Button colors at login and register page
• Title at login and register page
• All labels like Username.. email ...
• Text in button.

Default template config

config = {
        "LOGIN_BTN": "btn-success",
        "REGISTER_BTN": "btn-warning",

        "LOGIN_BTN_TEXT": "Login",
        "REGISTER_BTN_TEXT": "Register",

        "LOGIN_PAGE_TITLE": "Login",
        "REGISTER_PAGE_TITLE": "Register",

        "LOGIN_LABEL_USERNAME": "Username",
        "LOGIN_LABEL_PASSWORD": "Password",
        "REGISTER_LABEL_USERNAME": "Username",
        "REGISTER_LABEL_PASSWORD": "Password",
        "REGISTER_LABEL_EMAIL": "Email address"
}

p.s login-btn colors based on bootstrap classes

...
my_config = {
        "LOGIN_BTN": "btn-danger",
        "REGISTER_BTN": "btn-primary",

        "LOGIN_PAGE_TITLE": "Admin",
        "REGISTER_PAGE_TITLE": "Admin"
}
auth = Auth(app=app, db=db, template_config=my_config)
auth.init()
...

p.s if the some settings are not entered, they will remain in their state.
