#SAIL

Hi there,

I'm having trouble to print some data on a Grid.

We are using the following structure on a CDT (which is also a database on MySQL):

CDT1
          CDT2 (multiple)
                    field1
                    field2
                    field3

When I use a rule to filter my CDT1 and find the CDT2 objects which correspond to it,
I cannot print the field1, field2 and field3, because an error appears saying
they're not list type.

I understanded that the grid text column just prints an array, and my array is the
CDT2, not the fields inside of it. I want to know how can I print the fields on the Grid,
putting them inside an array. Is there some way to do this ?

I have a foreign key of my CDT1 inside my CDT2, but it cannot be used with Appian Query Rules.

Here's a practical example of what I'm trying to do:

a!gridTextColumn(
label: "Field1",
data: index(
local!datasubset.data.cdt2,
"cdt2.field1",
{}
),
field: "field1"
)

Thanks !

If I understand your requirements, here is how I would handle it:
1. Create a rule to create your form/report/dashboard/section, I will use a dashboard for this example.
=rule!APN_uiRecordDashboardOneColumn(
          load(
                              CDT1: rule!returnCDT1(pkId),
                              CDT2: tr[1].CDT2,
                              pageInfo: rule!APN_pagingInfo(
                                                                       startIndex: 1,
                                                                       batchSize: -1,
                                                                       sort: {field: "someFieldInCDT2", ascending: false}
                                                             ),
repPageInfo: rule!APN_generateRepeatedValueForArrayLength(CDT2,pageInfo),
                              repEmpty: rule!APN_generateRepeatedValueForArrayLength(CDT2,""),

                              apply(rule!generateCDT2Grid,merge(CDT2,repPageInfo,repEmpty))

          )/*End Load*/
)
The first variable 'CDT1' calls a query and returns cdt1.
The second variable 'CDT2' retrieves all of the CDT2's found in CDT1.
the other variables I created are just to pass to my second rule which will generate a grid to display the contents of CDT2.
The apply statement loops over all of my CDT2's and returns a grid for each CDT2.
Here is the rule I loop over in the apply() statement:
ruleName is generateCDT2Grid with inputs of CDT2 type=Any, value type=Any, saveInto type=Any

=rule!APN_uiSectionOneColumn(
label:CDT2.title,
contents:{if(rule!APN_arrayLength(CDT2)=0,
                              rule!APN_uiTextReadOnly(label:"",
                                                                                                     instructions:"",
                                                                                                     value:"No Records to Display.",
                                                                                                     hideWhenNull:true(),
                                                                                                     alternateText:""),
                               rule!APN_uiGrid(
                                                  label:"" ,
                                                  instructions:"",
                                                  columns: { rule!APN_uiGridTextColumn("Coumnn1","CDT2FieldName1",CDT2.column1,"LEFT"),
                                                                                rule!APN_uiGridTextColumn("Coumnn2","CDT2FieldName2",CDT2.column2,"LEFT"),
                                                                                rule!APN_uiGridTextColumn("Coumnn3","CDT2FieldName3",CDT2.column3,"LEFT")
                                                                       },
                                                  value: rule!APN_pagingInfoAll(),
                                                  saveInto: ri!saveInto,
                                                  totalCount: length(CDT2)
                                                  )
                              )},
hideWhenEmpty: true()
)

                                                             ),
