Fixed #23016 -- Updated FAQs per Aymeric's suggestions.

  "http://www.example.com/admin/" in your browser, in "myproject.settings" you

  should set :setting:`SESSION_COOKIE_DOMAIN` = 'www.example.com'.

* Some browsers (Firefox?) don't like to accept cookies from domains that

  don't have dots in them. If you're running the admin site on "localhost"

  or another domain that doesn't have a dot in it, try going to

  "localhost.localdomain" or "127.0.0.1". And set

  :setting:`SESSION_COOKIE_DOMAIN` accordingly.

I can't log in. When I enter a valid username and password, it brings up the login page again, with a "Please enter a correct username and password" error.

What are Django's prerequisites?

--------------------------------

Django requires Python, specifically Python 2.7 or 3.2 and above. No other

Python libraries are required for basic Django usage.

Django requires Python, specifically Python 2.7 or 3.2 and above. Other Python

libraries may be required for some uses, but you'll receive an error about it

as they're needed.

For a development environment -- if you just want to experiment with Django --

you don't need to have a separate Web server installed; Django comes with its

own lightweight development server. For a production environment, Django follows

the WSGI spec, :pep:`3333`, which means it can run on a variety of server

platforms. See :doc:`Deploying Django </howto/deployment/index>` for some

popular alternatives. Also, the `server arrangements wiki page`_ contains

details for several deployment strategies.

popular alternatives.

If you want to use Django with a database, which is probably the case, you'll

also need a database engine. PostgreSQL_ is recommended, because we're

PostgreSQL fans, and MySQL_, `SQLite 3`_, and Oracle_ are also supported.

What Python version should I use with Django?

---------------------------------------------

Third-party applications for use with Django are, of course, free to set their

own version requirements.

Will Django run under shared hosting (like TextDrive or Dreamhost)?

-------------------------------------------------------------------

See our `Django-friendly Web hosts`_ page.

Should I use the stable version or development version?

-------------------------------------------------------

as the admin interface to work; e.g., you need a simple way of being able to

specify an object to edit or delete.

Does Django support NoSQL databases?

------------------------------------

NoSQL databases are not officially supported by Django itself. There are,

however, a number of side project and forks which allow NoSQL functionality in

Django, like `Django non-rel`_.

You can also take a look on `the wiki page`_ which discusses some alternatives.

How do I add database-specific options to my CREATE TABLE statements, such as specifying MyISAM as the table type?

------------------------------------------------------------------------------------------------------------------

We try to avoid adding special cases in the Django code to accommodate all the

database-specific options such as table type, etc. If you'd like to use any of

these options, create an :ref:`SQL initial data file <initial-sql>` that

contains ``ALTER TABLE`` statements that do what you want to do. The initial

data files are executed in your database after the ``CREATE TABLE`` statements.

these options, create a migration with a

:class:`~django.db.migrations.operations.RunSQL` operation that contains

``ALTER TABLE`` statements that do what you want to do.

For example, if you're using MySQL and want your tables to use the MyISAM table

type, create an initial data file and put something like this in it::

type, use the following SQL::

    ALTER TABLE myapp_mytable ENGINE=MyISAM;

As explained in the :ref:`SQL initial data file <initial-sql>` documentation,

this SQL file can contain arbitrary SQL, so you can make any sorts of changes

you need to make.

We happen to think our template engine is the best thing since chunky bacon,

but we recognize that choosing a template language runs close to religion.

There's nothing about Django that requires using the template language, so

if you're attached to ZPT, Cheetah, or whatever, feel free to use those.

if you're attached to Jinja2, Cheetah, or whatever, feel free to use those.

Do I have to use your model/database layer?
