Hi,
I'm new to Lianja & am scripting in Python. If I take the Customers app described in the getting started guide as my base point. I would like to be able to modify this app so that I could display the order details in section 3 with the product name from the productsbyname table alongside the Product id.
I can't quite figure out how to do this.
All help much appreciated plus any pointers to additional documentation would be helpful

We will be adding in the ability to define additional columns to a Grid later. Currently you need to have a field in the table to drag onto the Grid. It can then be assigned to a memory variable as the Data Source (and the field can then be dragged into the Grid a second/subsequent time if required). Using the KEYLOOKUP() function in the Get data mapping attribute displays the matching data (the example_datamapping App also illustrates this).
Yvonne,
I'm probably doing something wrong but its not working.
I've set up a dummy field in the order_details table as you suggested.
I drag this over to the grid, although this will only allow the field at the end of the grid which is another issue.
I've set the data source as m.DUMMY2 (although I don't understand why as the field name is DUMMY) & the keylookup is as follows keylookup("products","productid",order_details.pro ductid,productname,"Not Found")
I have the example_datamapping App but can't find any documentation as to how that app was built so it doesn't teach me anything.

Yvonne,
I've quit Lianja & started it again & now the fields are showing ?! So my question is how do you change the positions of the fields within the grid - dragging doesn't seem to work

Hi David,Originally Posted by davidlane
on Windows RC5.5 dragging columns in a grid appears to be broken (worked in Linux). In RC5.6 released today it is fixed in Windows, and still works in Linux.

The 'm.' signifies what follows is a memory variable and it can be any valid identifier. The one in my screenshot was m.dummy2 as I had added 3 additional columns to the grid using the dummy field and had named them accordingly.I've set the data source as m.DUMMY2 (although I don't understand why as the field name is DUMMY)
Hank,
I'm using OS X 10.8.3 on a MacBook Pro - there appears to be some instability in the python code editor at the moment. quite often crashes when it hits something it doesn't like when saving - I can't give you much more detail at this stage as I've not been able to pinpoint it to anything in particular.
I'll download 5.6 & see how that goes.

David, If you have some simple example that is reproducible please attach it to a ticket so I can run it in debug mode.

Hank,
5.6 downloaded & installed. Unfortunately the problem is still there for OS X at least.

Hi David,
if you have a instance of Windows running in a VM on your Mac, I'd suggest installing 5.6 there: if it works for you there, then I'd suggest you submit a bug report for the Mac (since "user error" <s> will have been eliminated). You can test it right on the LianjaDemo opening page.
Hank
