Forum > Use of IWBootstrap and IW templates

06-06-2018, 12:17 PM:

Hi,

The question I have is using IWBootstrap (TIWBSText) with templates. I'm using IW14 so it's not the new integrated IWBootstrap version from IW15.

I use bootstrap-table and the REST method for loading the table. It's all from templates.

Code:

// connect dbGrid table to bootstrap-table object

$('#DBGRID').bootstrapTable(

{"columns":[

{"field":"product","title":"product"},

{"field":"aantal","title":"aantal"},

{"field":"afmeting","title":"afmeting"},

{"field":"status","title":"status"}

"url":"/$iwbs/DBGRID.dataurl",

"classes":"table table-striped table-no-bordered"});

// connect table cell click event handler

$("#DBGRID").off("click-cell.bs.table").on("click-cell.bs.table", function(e, field, value, row) {

ajaxCall("DBGRID.click-cell.bs.table","&row="+row.id, false);

});

</script>

Here the data for the table is fetched from "/$iwbs/DBGRID.dataurl". In the form an eventhandler picks up the request and outputs a json response.

This works if you set TIWServerController.AllowMultipleSessionsPerUser = False. If you set this property to True, the url that is referenced doesn't trigger the eventhandler.

Because I would like a solution that works in both situations I changed the url to "../$iwbs/DBGRID.dataurl" in the template. This works in both situations.

Question: "Is this the correct and preferred way to work with these urls?"

Using IW14.1.3 and Delphi 10.1

Hi Jeroen,

I haven't tested this code yet, but I guess the original URL should work in both situations. Not sure why it is failing when AllowMultipleSessionsPerUser = True. Your fix might work, but relative URLs are not always good in IW because it might work in some applications and will definitely fail in others.

Do you have a simple test case using this construction that you could send me? If so, my e-mail is alexandre [at] atozed dot com. It will save me some time... :-)

Cheers

Hi Alexandre,

I'll send you an example this week, no problem.
