-Where Django finds fixture files
---------------------------------
+Tell Django where to look for fixture files
+-------------------------------------------
+
+By default, Django looks for fixtures in the ``fixtures`` directory inside each
+app for, so the command ``loaddata sample`` will find the file
+``my_app/fixtures/sample.json``. This works with relative paths as well, so
+``loaddata my_app/sample`` will find the file
+``my_app/fixtures/my_app/sample.json``.
+
+Django also looks for fixtures in the list of directories provided in the
+:setting:`FIXTURE_DIRS` setting.
+
+To completely prevent default search form happening, use an absolute path to
+specify the location of your fixture file, e.g. ``loaddata /path/to/sample``.

-When running :djadmin:`manage.py loaddata <loaddata>`, you can also
-specify a path to a fixture file, which overrides searching the usual
-directories.
+    Django will use the first fixture file it finds whose name matches, so if
+    you have fixture files with the same name in different applications, you
+    will be unable to distinguish between them in your ``loaddata`` commands.
+    The easiest way to avoid this problem is by *namespacing* your fixture
+    files. That is, by putting them inside a directory named for their
+    application, as in the relative path example above.
