Mount your database as filesystem. |
48 |
|
|
49 |
|
Let's suppose that your database have table C<files> with following structure: |
50 |
|
|
51 |
|
id: int |
52 |
|
filename: text |
53 |
|
size: int |
54 |
|
content: text |
55 |
|
writable: boolean |
56 |
|
|
57 |
|
Following is example how to mount table like that to C</mnt>: |
58 |
|
|
59 |
my $mnt = Fuse::DBI->mount({ |
my $mnt = Fuse::DBI->mount({ |
60 |
filenames => 'select name from filenamefilenames, |
'filenames' => 'select id,filename,size,writable from files', |
61 |
read => 'sql read', |
'read' => 'select content from files where id = ?', |
62 |
update => 'sql update', |
'update' => 'update files set content = ? where id = ?', |
63 |
dsn => 'DBI:Pg:dbname=webgui', |
'dsn' => 'DBI:Pg:dbname=test_db', |
64 |
user => 'database_user', |
'user' => 'database_user', |
65 |
password => 'database_password' |
'password' => 'database_password', |
66 |
|
'invalidate' => sub { ... }, |
67 |
}); |
}); |

71 |
|
=over 5 |
72 |
|
|
73 |
|
=item filenames |
74 |
|
|
75 |
|
SQL query which returns C<id> (unique id for that row), C<filename>, |
76 |
|
C<size> and C<writable> boolean flag. |
77 |
|
|
78 |
|
=item read |
79 |
|
|
80 |
|
SQL query which returns only one column with content of file and has |
81 |
|
placeholder C<?> for C<id>. |
82 |
|
|
83 |
|
=item update |
84 |
|
|
85 |
|
SQL query with two pace-holders, one for new content and one for C<id>. |
86 |
|
|
87 |
|
=item dsn |
88 |
|
|
89 |
|
C<DBI> dsn to connect to (contains database driver and name of database). |
90 |
|
|
91 |
|
=item user |
92 |
|
|
93 |
|
User with which to connect to database |
94 |
|
|
95 |
|
=item password |
96 |
|
|
97 |
|
Password for connecting to database |
98 |
|
|
99 |
|
=item invalidate |
100 |
|
|
101 |
|
Optional anonymous code reference which will be executed when data is updated in |
102 |
|
database. It can be used as hook to delete cache (for example on-disk-cache) |
103 |
|
which is created from data edited through C<Fuse::DBI>. |
104 |
|
|
105 |
|
=item fork |
106 |
|
|
107 |
|
Optional flag which forks after mount so that executing script will continue |
108 |
|
running. Implementation is experimental. |

Size information (C<ls -s>) is wrong. It's a problem in upstream Fuse module |
594 |
|
(for which I'm to blame lately), so when it gets fixes, C<Fuse::DBI> will |
595 |
|
automagically pick it up. |
