list_model_info
===============

:synopsis: Lists out all the fields and methods for models in installed apps.

Introduction
------------

When working with large projects or when returning to a code base after some time away, it can be challenging to remember all of the
fields and methods associated with your models. This command makes it easy to see:

 * what fields are available
 * how they are referred to in queries
 * each field's class
 * each field's representation in the database
 * what methods are available
 * method signatures


Commandline arguments
^^^^^^^^^^^^^^^^^^^^^
You can configure the output in a number of ways.

::

  # Show each field's class
  $ ./manage.py list_model_info --field-class

::

  # Show each field's database type representation
  $ ./manage.py list_model_info --db-type


::

  # Show each method's signature
  $ ./manage.py list_model_info --signature

::

  # Show all model methods, including private methods and django's default methods
  $ ./manage.py list_model_info --all-methods

::

  # Output only information for a single model, specifying the app and model using dot notation
  $ ./manage.py list_model_info --model users.User


You can combine arguments. for instance, to list all methods and show the method signatures for the User model within the users app::

  $ ./manage.py list_model_info --all --signature --model users.User



Settings Configuration
^^^^^^^^^^^^^^^^^^^^^^

You can specify default values in your settings.py to simplify running this command.


.. tip::
   Commandline arguments override the following settings, allowing you to change options on the fly.


To show each field's class::

    MODEL_INFO_FIELD_CLASS = True

To show each field's database type representation::

    MODEL_INFO_DB_TYPE = True

To show each method's signature::

    MODEL_INFO_SIGNATURE = True

To show all model methods, including private methods and django's default methods::

    MODEL_INFO_ALL_METHODS = True

To output only information for a single model, specify the app and model using dot notation::

    MODEL_INFO_MODEL = 'users.User'
