|
48 |
|
|
49 |
* Retrieving objects from database. |
|
50 |
|
|
51 |
The DB model class is declared in ``object_class`` class attribute. Also, |
|
52 |
results can be filter using either the ``filters`` and ``excludes`` |
|
53 |
attribute or the "--filter-by" option. |
|
54 |
|
|
55 |
* Display specific fields of the database objects. |
|
56 |
|
|
57 |
List of available fields is defined in the ``FIELDS`` class attribute, |
|
58 |
which is a dictionary mapping from field names to tuples containing the |
|
59 |
way the field is retrieved and a text help message to display. The first |
|
60 |
field of the tuple is either a string containing a chain of attribute |
|
61 |
accesses (e.g. "machine.flavor.cpu") either a callable function, taking |
|
62 |
as argument the DB object and returning a single value. |
|
63 |
|
|
64 |
The fields that will be displayed be default is contained in the ``fields`` |
|
65 |
class attribute. The user can specify different fields using the "--fields" |
|
66 |
option. |
|
67 |
|
|
68 |
* Handling of user UUIDs and names. |
|
69 |
|
|
70 |
If the ``user_uuid_field`` is declared, then "--user" and "--display-mails" |
|
71 |
options will become available. The first one allows filtering via either |
|
72 |
a user's UUID or display name. The "--displayname" option will append |
|
73 |
the displayname of ther user with "user_uuid_field" to the output. |
|
74 |
|
|
75 |
* Pretty printing output to a nice table. |
