Méthode sqlalchemy.URL.create

Signature de la méthode create

def create(drivername: 'str', username: 'Optional[str]' = None, password: 'Optional[str]' = None, host: 'Optional[str]' = None, port: 'Optional[int]' = None, database: 'Optional[str]' = None, query: 'Mapping[str, Union[Sequence[str], str]]' = immutabledict({})) -> 'URL' 

Description

help(URL.create)

Create a new :class:`_engine.URL` object.

.. seealso::

    :ref:`database_urls`

:param drivername: the name of the database backend. This name will
  correspond to a module in sqlalchemy/databases or a third party
  plug-in.
:param username: The user name.
:param password: database password.  Is typically a string, but may
  also be an object that can be stringified with ``str()``.

  .. note:: The password string should **not** be URL encoded when
     passed as an argument to :meth:`_engine.URL.create`; the string
     should contain the password characters exactly as they would be
     typed.

  .. note::  A password-producing object will be stringified only
     **once** per :class:`_engine.Engine` object.  For dynamic password
     generation per connect, see :ref:`engines_dynamic_tokens`.

:param host: The name of the host.
:param port: The port number.
:param database: The database name.
:param query: A dictionary of string keys to string values to be passed
  to the dialect and/or the DBAPI upon connect.   To specify non-string
  parameters to a Python DBAPI directly, use the
  :paramref:`_sa.create_engine.connect_args` parameter to
  :func:`_sa.create_engine`.   See also
  :attr:`_engine.URL.normalized_query` for a dictionary that is
  consistently string->list of string.
:return: new :class:`_engine.URL` object.

.. versionadded:: 1.4

    The :class:`_engine.URL` object is now an **immutable named
    tuple**.  In addition, the ``query`` dictionary is also immutable.
    To create a URL, use the :func:`_engine.url.make_url` or
    :meth:`_engine.URL.create` function/ method.  To modify a
    :class:`_engine.URL`, use the :meth:`_engine.URL.set` and
    :meth:`_engine.URL.update_query` methods.
