tools.sessions.on Default: True Description: Enable sessions

engine.autoreload.on Default: False Description: Auto Reload when source code change. Don't use it in production.

Global Variable (config/globalvar.py)

directory.py is the place for storing your Global Variable.

GV_base_url Is the variable for your base URL (without / in the end)

GV_title Is the variable for your web title

Directory (config/directory.py)

directory.py is the place for storing your path. It is useful to calling the path more efficiently. there is 2 method that you can store your path. store it in variable for templating configuration, and store it as object for routing the url.

This is example that use for templating

html_user       = "static/pages-user"
template_user   = "static/template-user"

And this is example that use for routing the url

dirconfig = {
    '/' :
    {
        'tools.sessions.on'     : True ,
        'tools.staticdir.root'  : os.path.abspath(os.getcwd()) ,
    },
    '/your_dir' :
    {
        'tools.staticdir.on'    : True ,
        'tools.staticdir.dir'   : './static/your-dir' ,
    },
}

Templating (config/template.py)

Templating is useful when you had more than 1 website template for difference use case. For an example, when you had user and admin in the use case, the website for user have a navbar and footer, and the website for admin have a navbar and sidebar.

Before you create a template, make sure your directory configuration is ready for storing templates and pages. For an example:

html_user       = "static/pages-user"
template_user   = "static/template-user"

To create the template, you need to insert this code in def __init__(self)

self.html_pages_user        = html.main.get_html(directory.html_user)
self.html_template_user     = html.main.get_html(directory.template_user)

if you had admin template, you just need to add the code. for the example like this

self.html_pages_user        = html.main.get_html(directory.html_user)
self.html_template_user     = html.main.get_html(directory.template_user)

self.html_pages_admin       = html.main.get_html(directory.html_admin)
self.html_template_admin    = html.main.get_html(directory.template_admin)

and then you need create function for each of your template in main class like this

def user(self, page):
    params_list = {
        "template"  : self.html_template_user        ["user.html"           ]   ,
        "topnav"    : self.html_template_user        ["user-topnav.html"    ]   ,
        "container" : self.html_pages_user           [page+".html"          ]
    }
    return params_list

Database (config/database.py)

This is the sample template for configure it

db_default = {
    'host'          : 'localhost',
    'user'          : 'root',
    'password'      : '',
    'database'      : 'your_db',
    'autocommit'    : True,
}

You also can make more than 1 database configuration like this

db_default = {
    'host'          : 'localhost',
    'user'          : 'root',
    'password'      : '',
    'database'      : 'your_db',
    'autocommit'    : True,
}

db_other = {
    'host'          : 'localhost',
    'user'          : 'root',
    'password'      : '',
    'database'      : 'other_db',
    'autocommit'    : True,
}

Handling the modules

Handling the module is in handler.py.
