About userprofile

userprofile is a Pluggable application for TurboGears2 which provides a basic user profile page with forms to allow users to edit their own profile or change their password or email.

it’s curretly only compatible with ming but sqlalchemy compatibility can be added simply by adding the model

Installing

userprofile can be installed both from pypi or from github:

pip install tgapp-userprofile

should just work for most of the users

Plugging userprofile

In your application config/app_cfg.py import plug:

from tgext.pluggable import plug

Then at the end of the file call plug with userprofile:

plug(base_config, 'userprofile')

You will be able to access your profile at http://localhost:8080/userprofile.

Options

tgapp-userprofile supports some options that can be passed to the plug method to customize various aspects of the application:

  • user_partial - Path of a partial to display into the user profile page.
    Useful to add more data to the profile page without changing its template
  • custom_css - Path to a CSS file which will be used for the profile pages in place of the default one.

User Properties

tgapp-userprofile looks for various properties into the User class instances to drive its default behavior, the most important property is the profile_data property which can provide a dictionary with the user information to display on the profile page, but other properties are available to tune the behavior:

profile_data

A dictionary of entries to display into the profile page, the default dictionary is built with:

{'display_name':('Display Name', user.display_name),
 'email_address':('Email Address', user.email_address)}

each key of the dictionary if the id of the field, in most cases it will have the same name of the user property where that field is stored. Values of the dictionary are tuples where the first value is the name of the field which will be displayed and the second one is the real value of the field.

If an avatar key is available that is expected to provide the url of the avatar image of the user. If it is not available userprofile will look for a tgapp-fbauth facebook avatar or will falleback to the default avatar.

display_name key will be used as the profile page title.

profile_form

A ToscaWidgets or tw2 form that can be used to edit the user profile. By default an autogenerated one with a text field for each entry in profile_data is provided.

save_profile

A callable which will receive the user data submitted by the edit form and is expected to update the user accordingly.

By default values will be stored as they are into the user field with the same id provided into profile_data.

Bootstrap Layout

If you want use bootstrap for beautify style of UserForm or ChangePasswordForm form layout, in your app_cfg:

def replace_profile_form_layout():
    from axf.bootstrap import BootstrapFormLayout
    from userprofile.lib import UserForm
    from userprofile.lib import ChangePasswordForm

    UserForm.child = BootstrapFormLayout(children=UserForm.child.children)
    UserForm.submit.css_class = 'btn-primary form-control'

    ChangePasswordForm.child = BootstrapFormLayout(children=ChangePasswordForm.child.children)
    ChangePasswordForm.submit.css_class = 'btn-primary form-control'

milestones.config_ready.register(replace_profile_form_layout)

Authentication Configuration

Since with userprofile a user can change his email address or user name, you have to configure repoze.who properly. In app_cfg.py, locate the authenticate method of ApplicationAuthMetadata: it should return the id of the user. Now repoze.who will save the user id in a cookie to identify the user and since this id will not change, the authentication process allows users to change email addresses and user names safely.

This example illustrate a login based on user name or email address with Ming:

class ApplicationAuthMetadata(TGAuthMetadata):
    def __init__(self, sa_auth):
        self.sa_auth = sa_auth

    def get_query(self, login):

        try:
            _id = ObjectId(login)
        except InvalidId:
            _id = login

        return {
            '$or': [{'email_address': login},
                    {'user_name': login},
                    {'_id': _id}],
            'blocked': {'$ne': True},
        }

    def authenticate(self, environ, identity):
        login = identity['login']
        user = self.sa_auth.user_class.query.find(self.get_query(login)).first()

        if not user:  # pragma: no cover
            login = None
        elif not user.validate_password(identity['password']):
            login = None

        if login is None:
            try:
                from urllib.parse import parse_qs, urlencode
            except ImportError:
                from urlparse import parse_qs
                from urllib import urlencode
            from tg.exceptions import HTTPFound

            params = parse_qs(environ['QUERY_STRING'])
            params.pop('password', None)  # Remove password in case it was there
            if user is None:  # pragma: no cover
                params['failure'] = 'user-not-found'
            else:
                params['login'] = identity['login']
                params['failure'] = 'invalid-password'

            # When authentication fails send user to login page.
            environ['repoze.who.application'] = HTTPFound(
                location=environ['SCRIPT_NAME'] + '?'.join(('/login', urlencode(params, True)))
            )

        return str(user._id) if user and login else login

    def get_user(self, identity, userid):
        return self.sa_auth.user_class.query.find(self.get_query(userid)).first()

    def get_groups(self, identity, userid):
        return [g.group_name for g in identity['user'].groups]

    def get_permissions(self, identity, userid):
        return [p.permission_name for p in identity['user'].permissions]


base_config.sa_auth.authmetadata = ApplicationAuthMetadata(base_config.sa_auth)
