Hello.

Is it easy enough to create an additional column in the list view that I can use to create a link next to each row to take me to an external page? The kicker is that the column is not associated with a field of any kind.

For example: It would be nice if I can add a link next to each row like this: <a target="_blank" href="htp://www.fakedomain.com/viewpdf.php?table=some-table&id=1">view as pdf</a>

Where "id=#" is a number based on the row being displayed.

I assume it would be a delagate class. Could you give us an idea of how to go about this?

Thanks.

A little cheat that I often do in this case is I create a grafted field via the __sql__ directive in the fields.ini file. Then I override the renderCell method for this field in the delegate class to show the link.

You'll also need to use the noLinkFromListView=1 directive on this field so that Xataface won't try to wrap the whole cell in a link...

e.g. fields.ini

Code: Select all

__sql__ = "select t.*, null as mytransientfield from mytable t"

[mytransientfield]
    noLinkFromListView=1


Delegate class:

Code: Select all

...
function mytransientfield__renderCell($record){
    return '<a target="_blank" href="...">view as pdf</a>';
}

...


Excellent solution. Thanks!

I think im on the right track by posting on this thread already. Im trying to do a similar thing. Trying to add a related column onto a tables list view. Can this be done?
The table is related already so you can see its data in details view. I just want to see that related column in list view, and if the record has more than 1 related record, show the most recent field.

You'll want to do a custom __sql__ query and graft the field onto your table.
e.g.

Code: Select all

__sql__ = "select b.*,
    (
        select relatedcol from relatedtable r where r.baseid=b.baseid order by r.created desc limit 1
    ) as relatedcol
    from basetable b"


NOte: Haven't tested this.

is this sql query as you have written done it __sql___ put anywhere in the tables fields.ini? and then just below the query i do the [graftedfield]? am i correct?

It should be at the beginning of the fields.ini file.

Hello all.
Say I have a table with a grafted column coming from another table like such

fields.ini

Code: Select all

__sql__ = "SELECT b.*,
  (
        SELECT ReviewDate from status r WHERE r.MatterID=b.MatterID ORDER BY r.ReviewDate DESC LIMIT 1
    ) as ReviewDate
    from matters b"

[ReviewDate]
filter = 1
widget:label = "Review Date"
validators:required = false
vocabulary = ReviewDate
visibility:browse=hidden

and then i wanted to by default only show rows where something = something like such

matters.php

Code: Select all

function __sql__(){
return "SELECT * FROM `matters` WHERE `User` = current user ";
}

the grafted column "ReviewDate" disappears....
How can I somehow do the filter, before grafting that column?

The __sql__() method in the delegate class completely overrides the __sql__ directive in the fields.ini file. If you are using the delegate class method, then make sure it includes all of the grafted fields that you need.

Yeah this kinda coincides with this thread: http://xataface.com/forum/viewtopic.php?f=4&t=6868&p=30844#p30844
If I can figure the LoggedInUserName+YES/NO filter by default, without breaking my grafted ReviewDate column, both these threads will be resolved!

experimentation continues
Thankyou,
