Entity Reference Not Working As Expected in Plugin

(0) ShareShare
ReportReport
Posted on by Steve Kessler 25

A relationship for the CRM Product entity has been created in the code I am working with. 

Later in the code, we get:

    invoiceItem["client_name"] = product.Name;

I know this works.

I am trying to do the following, immediately after that code:

  invoiceItem["client_extendeddescription"] = product.GetAttributeValue<string>("client_extendeddescription");

Visual Studio Reports: "EntityReference does not contain definition GetAttributeValue and accessible extension method 'GetAttributeValue' could not be found"

If from the product entity I can get the name why can I not get a field value? I appreciate the help.  I am new to the C#/Plugin development side so I hope this is not a stupid question. 

Thanks,

Steve

    This line cannot throw that error message as we are not doing any entity operation here. Is it possible to debug and see where exactly it is failing.

    Okay, I think the issue is coming from later in the code. Here is what I just added.

    Screen-Shot-2019_2D00_07_2D00_31-at-8.58.01-PM.png

    Here is the line I think is the issue but it was working before I made the change above. 

    invoiceItem["client_productid"] = new EntityReference("dmcc_product", billingproduct.GetAttributeValue<EntityReference>("client_productid").Id);

    Thanks,

    Steve

    Hi Steve,

    Something is not correct there. Can you share a screenshot with the error message? This error message meaanas that we are trying to retrieve an entity record and have passed "Client_product" as the entity name but this name is not correct.

    Ravi,

    Thank you for this great response. This makes perfect sense.  I think I am almost there.

    I added:

    var productEnt = service.Retrieve(product.LogicalName, product.Id, new ColumnSet("client_extendeddescription"));

    invoiceItem["client_extendeddescription"] = productEnt.GetAttributeValue<string>("client_extendeddescription");

    The error message I get back when running the code is that "The entity with a name = 'client_product' with namemapping = 'Logical' was not found in the MetadataCache. "

    This does not make sense because we are looking at the core product entity rather than a custom entity called client_product.

    Thanks,

    Steve

    Hi,

    Entity reference doesn't contains the attributes. It only contains the entity logical name, entity guid and in some cases name of the record.

    In order to get the fields, you first need to retrieve the Entity object and then you can use GetAttributeValue.

    Refer below code to get the entity from the entity reference-

    var productEnt = service.Retrieve(product.LogicalName, product.Id, new ColumnSet(true));

    Hope this helps.
