Q: How can I refresh a comment/subreddit/submission?

A: Directly calling the constructors will refresh the value:

.. code-block:: python

    reddit.comment(comment.id)
    reddit.subreddit(subreddit.display_name)
    reddit.submission(submission.id)

.. _faq2:

Q: Whenever I try to do anything, I get an ``invalid_grant`` error. What is the cause?

A: This means that either you provided the wrong password and/or the account you are
trying to sign in with has 2FA enabled, and as such, either needs a 2FA token or a
refresh token to sign in. A refresh token is preferred, because then you will not need
to enter a 2FA token in order to sign in, and the session will last for longer than an
hour. Refer to :ref:`2fa` and :ref:`refresh_token` in order to use the respective auth
methods.

.. _faq3:

Q: Some options (like getting moderator logs from r/mod) keep on timing out. How can I
extend the timeout?

A: Set the timeout config option or initialize :class:`.Reddit` with a timeout of your
choosing. Another option is to construct a :class:`.Subreddit` instance with a subset of
subreddits (concatenated with ``+``) that you want logs from like so:

.. code-block:: python

    reddit.subreddit("pics+LifeProTips")

Q: Help, I keep on getting redirected to ``/r/subreddit/login/``!

Q2: I keep on getting this exception:

.. code-block:: text

    prawcore.exceptions.Redirect: Redirect to /r/subreddit/login/ (You may be trying to perform a non-read-only action via a read-only instance.)

A: PRAW is most likely in read-only mode. This normally occurs when PRAW is
authenticated without a username and password or a refresh token. In order to perform
this action, the :class:`.Reddit` instance needs to be authenticated. See
:ref:`oauth_options` to see the available authentication methods.

.. _faq5:

Q: Help, searching for URLs keeps on redirecting me to ``/submit``!

Q2: I keep on getting this exception: ``prawcore.exceptions.Redirect: Redirect to
/submit``

A: Reddit redirects URL searches to the submit page of the URL. To search for the URL,
prefix ``url:`` to the url and surround the url in quotation marks.

For example, the code block:

.. code-block:: python

    reddit.subreddit("all").search("https://google.com")

Will become this code block:

.. code-block:: python

    reddit.subreddit("all").search('url:"https://google.com"')
