    19 RSS Channel Example

    21 

    22 Assuming you have several blog entries, click on the title of the

    23 search box in the left column. A larger search box should appear. Enter:

    24 

    25 .. sourcecode:: sql

    26 

    27    Any X ORDERBY D WHERE X is BlogEntry, X creation_date D

    28 

    29 and you get a list of blog entries.

    30 

    31 Click on your login at the top right corner. Chose "user preferences",

    32 then "boxes", then "possible views box" and check "visible = yes"

    33 before validating your changes.

    34 

    35 Enter the same query in the search box and you will see the same list,

    36 plus a box titled "possible views" in the left column. Click on

    37 "entityview", then "RSS".

    38 

    39 You just applied the "RSS" view to the RQL selection you requested.

    40 

    41 That's it, you have a RSS channel for your blog.

    42 

    43 Try again with:

    44 

    45 .. sourcecode:: sql

    46 

    47     Any X ORDERBY D WHERE X is BlogEntry, X creation_date D,

    48     X entry_of B, B title "MyLife"

    49 

    50 Another RSS channel, but a bit more focused.

    51 

    52 A last one for the road:

    53 

    54 .. sourcecode:: sql

    55 

    56     Any C ORDERBY D WHERE C is Comment, C creation_date D LIMIT 15

    57 

    58 displayed with the RSS view, that's a channel for the last fifteen

    59 comments posted.

    63 * show that the RSS view can be used to display an ordered selection

    64   of blog entries, thus providing a RSS channel

    65 

    66 * show that a different selection (by category) means a different channel
