Where() in macro use variable or field name

Szymon Mosiolek asked on September 4, 2017 14:39


I am building email template and want use macro with where() which will use variable or fild name. I have Order table with fieled "GarageId" and Garage table have the same filed as "DealerId" so in email templeate I want use macro which will pull garage details based on the ID. Here what I have:

  {%Documents.ClassNames("XXX.Garage").WithAllData.Where("DealerId = '94917'")[0].GetValue ("OfficeName") %}

This works fine, I am getting the right garage name so now I want use value from Order table so to display garage ID, I use:

{% Order.GarageId %}

Again I am getting right ID of garage which I choosen, so now I want combine both and have:

{% Documents.ClassNames("XXX.Garage").WithAllData.Where("DealerId = Order.GarageId")[0].GetValue ("OfficeName") %}

And this time I got nothing, so I tried with var and even converted value to sting:

{% if(Order.GarageId != null){
     id = Order.GarageId; 

Still nothing and I don't have any idea how to force where to compare these two values.

I think the problem is missing single quotes in your second as opposed to first example. That's the difference I can see. You need to check if your query accepts OrderId with or without single quotes.

Thanks, Chetan

Hi Szymon,

You should try this to combine both if you get this value correctly using macro {%Order.GarageId%}.

{% Documents.ClassNames("XXX.Garage").WithAllData.Where(string.Format("DealerId={0}", Order.GarageId))[0].GetValue("OfficeName") %}

Happy to help you!

Prashant unfortunatly this dosent work, I can't see how Where() matching GarageId with DealerId to pull data from Garages table. There are many garages so I have to match Id's to pull data from right garage.

My couleges suggesting using System.Linq library and this:

{%Documents.ClassNames("Protyre.Garage").WithAllData.Where(x => x.DealerId == Order.GarageId )[0].GetValue ("OfficeName") %}

But this dosen't work. Now I am thinking of creating custom macro and inside #c file I can use Where(), any thought if this is doable/right direction?

{%Documents.ClassNames("XXX.Garage").WithAllData.Where("DealerId = { %}{% FieldValue %}")[0].GetValue ("OfficeName") {% } %}

try above code once. it should work.
