11 a single database column.
12
13 See :doc:`/topics/db/models`.
14
15 generic view
16 A higher-order :term:`view` function that provides an abstract/generic
17 implementation of a common idiom or pattern found in view development.
18
19 See :doc:`/ref/generic-views`.
20

23

25
26 MTV

28 a better description of the way Django does things.
29
30 See :ref:`the FAQ entry <faq-mtv>`.

38 project
39 A Python package -- i.e. a directory of code -- that contains all the
40 settings for an instance of Django. This would include database
41 configuration, Django-specific options and application-specific
42 settings.
43
44 property
45 Also known as "managed attributes", and a feature of Python since
46 version 2.2. From `the property documentation`__:
47
48 Properties are a neat way to implement attributes whose usage
49 resembles attribute access, but whose implementation uses method
50 calls. [...] You
51 could only do this by overriding ``__getattr__`` and
52 ``__setattr__``; but overriding ``__setattr__`` slows down all
53 attribute assignments considerably, and overriding ``__getattr__``
54 is always a bit tricky to get right. Properties let you do this
55 painlessly, without having to override ``__getattr__`` or
56 ``__setattr__``.

60 queryset
61 An object representing some set of rows to be fetched from the database.
62
63 See :doc:`/topics/db/queries`.
64
65 slug
66 A short label for something, containing only letters, numbers,
67 underscores or hyphens. They're generally used in URLs. For
68 example, in a typical blog entry URL:
69
70 .. parsed-literal::
71
72 http://www.djangoproject.com/weblog/2008/apr/12/**spring**/
73
74 the last bit (``spring``) is the slug.
75
76 template
77 A chunk of text that acts as formatting for representing data. A
78 template helps to abstract the presentation of data from the data
79 itself.
80
81 See :doc:`/topics/templates`.
82
83 view
84 A function responsible for rending a page.
