Introduction |
13 |
------------ |
14 |
|
15 |
Gedafe (Generic Database Front-End) is an application independent |
16 |
end-user web front-end for databases. Application independant means, |
17 |
that the front-end doesn't have any information about the structure |
18 |
and contents of the database. |
19 |
|
20 |
The idea behind Gedafe is to put all the application logic into the |
21 |
database, along with meta-information on how to present the data. |
22 |
The front-end then gathers this information and uses it to build the |
23 |
user interface. This approach greatly reduces development time since |
24 |
you only have to develop the application at the database level and |
25 |
the web front-end comes for free. |
26 |
|
27 |
And there is more: |
28 |
|
29 |
* Gedafe uses a flexible templating system. It allows you |
30 |
customize the look of the user interface to a large degree. |
31 |
|
32 |
* Gedafe generated interfaces support "deep linking". This |
33 |
means that you can bookmark every page as it is presented. |
34 |
|
35 |
* At the moment Gedafe works only with PostgreSQL. But the |
36 |
structure of the application does not depend on PostgreSQL. |
37 |
|
38 |
* Gedafe is *NOT* yet another database-administration front-end |
39 |
with table editing ability. It is a real user interface. |

Release Notes |
42 |
------------- |
43 |
|
44 |
* PearlReports have been integrated with gedafe. It is now possible |
45 |
to write perl modules (pearls) which will be picked up by gedafe |
46 |
and presented in the "Entry" screen. The idea is to use this |
47 |
facility for generating complex, structured (multi-level) reports. |
48 |
Pearls have access to gedafes Webform generator as well a to the |
49 |
database handle. |
50 |
|
51 |
* More widgets: the 'widget' attribute of the meta_fields |
52 |
can now specify more widgets and widgets can now have parameters. |
53 |
For example with 'idcombo(combo=...)' another combo-box can be |
54 |
selected instead of the one chosen by Gedafe. |
55 |
|
56 |
* Blobs (files) can now be inserted into bytea columns if you have |
57 |
Postgresql >= 7.2 |
58 |
|
59 |
* Referencing large tables can now be done trough a java applet |
60 |
instead of a html select widget. This makes large (>100 rows or a |
61 |
few kb) tables more easy to use. |
62 |
|
63 |
* Dates can now be entered with a special 'date' widget. |
64 |
|
65 |
* Data can now be scanned for tokens resembling web objects (e.g. |
66 |
e-mail addresses, http urls), and automatically marked up to be |
67 |
hyper links. Set the 'markup' attribute to 1 in meta_fields for the |
68 |
desired column. |
69 |
|
70 |
* Gedafe can now count the total number of results returned from the |
71 |
database. This is helpful for seeing the number of items found by a |
72 |
search, and in skipping to the beginning end or of a result set. |
73 |
|
74 |
* If you have the Text::CSV_XS Perl module installed (available from CPAN), |
75 |
gedafe automatically detects it, and gives the option of exporting data |
76 |
either in CSV format (comma-separated-values), or in tab-delimited format. |
77 |
CSV format is useful for data with embedded newlines characters. |
78 |
|
79 |
* The meta_fields attribute 'align' can be used to change the alignment |
80 |
of a coulumn. |
81 |
|
82 |
* The buttons in the list view (with the arrows for navigation and 'ADD' to |
83 |
add a new record) can now also appear at the top before the list. |
84 |
