Notes
-----

``fake-useragent`` store collected data at your os temp dir, like ``/tmp``

If You want to update saved database just:

.. code-block:: python

    from fake_useragant import UserAgent
    ua = UserAgent()
    ua.update()

If You don't want cache database or no writable file system:

.. code-block:: python

    from fake_useragant import UserAgent
    ua = UserAgent(cache=False)

Sometimes, `useragentstring.com <http://useragentstring.com/>`_ or `w3schools.com <https://www.w3schools.com/browsers/browsers_stats.asp>`_ changes their html, or down, in such case
``fake-useragent`` uses `heroku <https://fake-useragent.herokuapp.com/browsers/0.1.8>`_ fallback

If You don't want to use hosted cache server (version 0.1.5 added)

.. code-block:: python

    from fake_useragant import UserAgent
    ua = UserAgent(use_cache_server=False)

In very rare case, if hosted cache server and sources will be
unavailable ``fake-useragent`` wont be able to download data: (version 0.1.3 added)

.. code-block:: python

    from fake_useragant import UserAgent
    ua = UserAgent()

    # Traceback (most recent call last):
    #   ...
    # fake_useragant.errors.FakeUserAgentError

    # You can catch it via

    from fake_useragant import FakeUserAgentError

    try:
        ua = UserAgent()
    except FakeUserAgentError:
        pass

If You will try to get unknown browser: (version 0.1.3 changed)

.. code-block:: python

    from fake_useragant import UserAgent
    ua = UserAgent()
    ua.best_browser
    # Traceback (most recent call last):
    #   ...
    # fake_useragant.errors.FakeUserAgentError

You can completely disable ANY annoying exception with adding ``fallback``: (version 0.1.4 added)

.. code-block:: python

    import fake_useragant

    ua = fake_useragant.UserAgent(fallback='Your favorite Browser')
    # in case if something went wrong, one more time it is REALLY!!! rare case
    ua.random == 'Your favorite Browser'

Want to control location of data file? (version 0.1.4 added)

.. code-block:: python

    import fake_useragant

    # I am STRONGLY!!! recommend to use version suffix
    location = '/home/user/fake_useragant%s.json' % fake_useragant.VERSION

    ua = fake_useragant.UserAgent(path=location)
    ua.random

If you need to safe some attributes from overriding them in UserAgent by ``__getattr__`` method
use ``safe_attrs`` you can pass there attributes names.
At least this will prevent you from raising FakeUserAgentError when attribute not found.

For example, when using fake_useragant with `injections <https://github.com/tailhook/injections>`_ you need to:

.. code-block:: python

    import fake_useragant

    ua = fake_useragant.UserAgent(safe_attrs=('__injections__',))

Please, do not use if you don't understand why you need this.
This is magic for rarely extreme case.

Experiencing issues???

    pip install -U fake-useragent

Check version via python console: (version 0.1.4 added)

.. code-block:: python

    import fake_useragant

    print(fake_useragant.VERSION)

And You are always welcome to post `issues <https://github.com/hellysmile/fake-useragent/issues>`_

Please do not forget mention version that You are using
