Introduction
------------
Flask-Admin is a batteries-included, simple-to-use `Flask <http://flask.pocoo.org/>`_ extension that lets you
add admin interfaces to Flask applications. It is inspired by the *django-admin* package, but implemented in such
a way that the developer has total control of the look, feel and functionality of the resulting application.
Out-of-the-box, Flask-Admin plays nicely with various ORM's, including
- `SQLAlchemy <http://www.sqlalchemy.org/>`_,
- `MongoEngine <http://mongoengine.org/>`_,
- `pymongo <http://api.mongodb.org/python/current/>`_ and
- `Peewee <https://github.com/coleifer/peewee>`_.
It also boasts a simple file management interface and a `redis client <http://redis.io/>`_ console.
The biggest feature of Flask-Admin is flexibility. It aims to provide a set of simple tools that can be used for
building admin interfaces of any complexity. So, to start off with you can create a very simple application in no time,
with auto-generated CRUD-views for each of your models. But then you can go further and customize those views & forms
as the need arises.
Flask-Admin is an active project, well-tested and production ready.
Examples
--------
Several usage examples are included in the */examples* folder. Please add your own, or improve
on the existing examples, and submit a *pull-request*.
To run the examples in your local environment::
1. Clone the repository::
git clone https://github.com/flask-admin/flask-admin.git
cd flask-admin
2. Create and activate a virtual environment::
virtualenv env -p python3
source env/bin/activate
3. Install requirements::
pip install -r 'examples/sqla/requirements.txt'
4. Run the application::
python examples/sqla/run_server.py
Documentation
-------------
Flask-Admin is extensively documented, you can find all of the documentation at `https://flask-admin.readthedocs.io/en/latest/ <https://flask-admin.readthedocs.io/en/latest/>`_.
The docs are auto-generated from the *.rst* files in the */doc* folder. So if you come across any errors, or
if you think of anything else that should be included, then please make the changes and submit them as a *pull-request*.
To build the docs in your local environment, from the project directory::
tox -e docs-html
And if you want to preview any *.rst* snippets that you may want to contribute, go to `http://rst.ninjs.org/ <http://rst.ninjs.org/>`_.
Installation
------------
To install Flask-Admin, simply::
pip install flask-admin
Or alternatively, you can download the repository and install manually by doing::
git clone git@github.com:flask-admin/flask-admin.git
cd flask-admin
python setup.py install
Tests
-----
Test are run with *nose*. If you are not familiar with this package you can get some more info from `their website <https://nose.readthedocs.io/>`_.
To run the tests, from the project directory, simply::
pip install -r requirements-dev.txt
nosetests
You should see output similar to::
.............................................
----------------------------------------------------------------------
Ran 102 tests in 13.132s
OK
For all the tests to pass successfully, you'll need Postgres & MongoDB to be running locally. For Postgres::
> psql postgres
CREATE DATABASE flask_admin_test;
\q
> psql flask_admin_test
CREATE EXTENSION postgis;
CREATE EXTENSION hstore;
You can also run the tests on multiple environments using *tox*.
3rd Party Stuff
---------------
Flask-Admin is built with the help of `Bootstrap <http://getbootstrap.com/>`_, `Select2 <https://github.com/ivaynberg/select2>`_
and `Bootswatch <http://bootswatch.com/>`_.
If you want to localize your application, install the `Flask-BabelEx <https://pypi.python.org/pypi/Flask-BabelEx>`_ package.
You can help improve Flask-Admin's translations through Crowdin: https://crowdin.com/project/flask-admin

MarkupSafe
==========
MarkupSafe implements a text object that escapes characters so it is
safe to use in HTML and XML. Characters that have special meanings are
replaced so that they display as the actual characters. This mitigates
injection attacks, meaning untrusted user input can safely be displayed
on a page.
Installing
----------
Install and update using `pip`_:
.. code-block:: text
pip install -U MarkupSafe
.. _pip: https://pip.pypa.io/en/stable/quickstart/
Examples
--------
.. code-block:: pycon
>>> from markupsafe import Markup, escape
>>> # escape replaces special characters and wraps in Markup
>>> escape('<script>alert(document.cookie);</script>')
Markup(u'&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
>>> # wrap in Markup to mark text "safe" and prevent escaping
>>> Markup('<strong>Hello</strong>')
Markup('<strong>hello</strong>')
>>> escape(Markup('<strong>Hello</strong>'))
Markup('<strong>hello</strong>')
>>> # Markup is a text subclass (str on Python 3, unicode on Python 2)
>>> # methods and operators escape their arguments
>>> template = Markup("Hello <em>%s</em>")
>>> template % '"World"'
Markup('Hello <em>&#34;World&#34;</em>')

*werkzeug* German noun: "tool". Etymology: *werk* ("work"), *zeug* ("stuff")
Werkzeug is a comprehensive `WSGI`_ web application library. It began as
a simple collection of various utilities for WSGI applications and has
become one of the most advanced WSGI utility libraries.
It includes:
- An interactive debugger that allows inspecting stack traces and
source code in the browser with an interactive interpreter for any
frame in the stack.
- A full-featured request object with objects to interact with
headers, query args, form data, files, and cookies.
- A response object that can wrap other WSGI applications and handle
streaming data.
- A routing system for matching URLs to endpoints and generating URLs
for endpoints, with an extensible system for capturing variables
from URLs.
- HTTP utilities to handle entity tags, cache control, dates, user
agents, cookies, files, and more.
- A threaded WSGI server for use while developing applications
locally.
- A test client for simulating HTTP requests during testing without
requiring running a server.
Werkzeug is Unicode aware and doesn't enforce any dependencies. It is up
to the developer to choose a template engine, database adapter, and even
how to handle requests. It can be used to build all sorts of end user
applications such as blogs, wikis, or bulletin boards.
`Flask`_ wraps Werkzeug, using it to handle the details of WSGI while
providing more structure and patterns for defining powerful
applications.
Installing

# Blinker
Blinker provides a fast dispatching system that allows any number of
interested parties to subscribe to events, or "signals".
Signal receivers can subscribe to specific senders or receive signals
sent by any sender.
>>> from blinker import signal
>>> started = signal('round-started')
>>> def each(round):
... print "Round %s!" % round
...
>>> started.connect(each)
>>> def round_two(round):
... print "This is round two."
...
>>> started.connect(round_two, sender=2)
>>> for round in range(1, 4):
... started.send(round)
...
Round 1!
Round 2!
This is round two.
Round 3!
See the [Blinker documentation](https://pythonhosted.org/blinker/) for more information.
## Requirements
Blinker requires Python 2.4 or higher, Python 3.0 or higher, or Jython 2.5 or higher.
## Changelog Summary
1.3 (July 3, 2013)
- The global signal stash behind blinker.signal() is now backed by a
regular name-to-Signal dictionary. Previously, weak references were
held in the mapping and ephemeral usage in code like
``signal('foo').connect(...)`` could have surprising program behavior
depending on import order of modules.
- blinker.Namespace is now built on a regular dict. Use
blinker.WeakNamespace for the older, weak-referencing behavior.
- Signal.connect('text-sender') uses an alternate hashing strategy to
avoid sharp edges in text identity.
1.2 (October 26, 2011)
- Added Signal.receiver_connected and Signal.receiver_disconnected
per-Signal signals.
- Deprecated the global 'receiver_connected' signal.
- Verified Python 3.2 support (no changes needed!)
1.1 (July 21, 2010)
- Added ``@signal.connect_via(sender)`` decorator
- Added ``signal.connected_to`` shorthand name for the
``temporarily_connected_to`` context manager.
1.0 (March 28, 2010)
- Python 3.x compatibility
0.9 (February 26, 2010)
- Sphinx docs, project website
- Added ``with a_signal.temporarily_connected_to(receiver): ...`` support

# `getwch` does not share this probably-bugged behavior. Moreover, it
# returns a Unicode object by default, which is what we want.
#
# Either of these functions will return \x00 or \xe0 to indicate
# a special key, and you need to call the same function again to get
# the "rest" of the code. The fun part is that \u00e0 is
# "latin small letter a with grave", so if you type that on a French
# keyboard, you _also_ get a \xe0.
# E.g., consider the Up arrow. This returns \xe0 and then \x48. The
# resulting Unicode string reads as "a with grave" + "capital H".
# This is indistinguishable from when the user actually types
# "a with grave" and then "capital H".
#
# When \xe0 is returned, we assume it's part of a special-key sequence
# and call `getwch` again, but that means that when the user types
# the \u00e0 character, `getchar` doesn't return until a second
# character is typed.
# The alternative is returning immediately, but that would mess up
# cross-platform handling of arrow keys and others that start with
# \xe0. Another option is using `getch`, but then we can't reliably
# read non-ASCII characters, because return values of `getch` are
# limited to the current 8-bit codepage.
