Posted on by k3000

Hello

I have the code below which works fine in pre-operation and pre-image. But I need it to work in post-operation. Any ideas on how to adjust the code?

using System;
using Microsoft.Xrm.Sdk;

namespace CalculateScorePlugin
{
    public class CalculateScore : IPlugin
    {
        public void Execute(IServiceProvider serviceProvider)
        {
            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
            IOrganizationServiceFactory servicefactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            IOrganizationService client = servicefactory.CreateOrganizationService(context.UserId);
            {
                if (context.InputParameters.Contains("Target"))
                {
                    if (context.InputParameters["Target"] is Entity)
                    {
                        Entity entity = (Entity)context.InputParameters["Target"];
                        if (entity.LogicalName == "contact")
                        {
                            if (entity.Attributes.Contains("crmn_ourdescription"))
                            {
                                try
                                {
                                    Entity image = context.PreEntityImages["image"];
                                    /*
                                    int sumFakturert = image.GetAttributeValue<int>("crmn_invoiceamount");
                                    int antTimerOrdinarTid = image.GetAttributeValue<int>("crmn_workinghoursordinary");
                                    int antOppdrag = image.GetAttributeValue<int>("crmn_assignmentinvolvements");
                                    */
                                    int kundelikes = image.GetAttributeValue<int>("new_kundelikes");
                                    String forsteVurdering = image.FormattedValues["new_frstegangsvurdering"].ToString();

                                    int score = kundelikes * 100;


                                    entity.Attributes["description"] = score.ToString();
                                    //entity.Attributes.Add("description", test);
                                    //client.Update(entity);
                                }
                                catch (Exception ex)
                                {
                                    throw new InvalidPluginExecutionException("Howdy! An error occured in the plugin:", ex);
                                }
                            }

                        }
                        else return;
                    }
                }
            }

        }
    }
}

Hi k3000,

just change:

context.PreEntityImages["image"]; --> context.PostEntityImages["image"]; // remember to register post entity image

A good practice is to use a new "clean" entity to update current entity to avoid updating the same values, like:

Entity updateentity = new Entity(entity.LogicalName);

updateentity.Id = entity.Id;

updateentity["new_mychangeattribute"] = mychangedvalue;

client.Update(updateentity);

Please let me know if you solve.

Reinforcing Francesco's comment:

Use a separate entity to update the Current record:

Entity contact = new Entity("contact");

contact.Id = entity.Id;

contact["description"] = score.ToString();

service.Update(contact);

Hope this helps.

perfect! I knew about the PostEntityImages part, but i couldn't figure out how to avoid ending up in a loop. Now it works. Thank you!

Code with required changes:

using System;

using Microsoft.Xrm.Sdk;

namespace CalculateScorePlugin

{

public class CalculateScore : IPlugin

{

public void Execute(IServiceProvider serviceProvider)

{

IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

IOrganizationServiceFactory servicefactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

IOrganizationService client = servicefactory.CreateOrganizationService(context.UserId);

{

if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)

{

Entity entity = (Entity)context.InputParameters["Target"];

if (entity.LogicalName == "contact")

{

if (entity.Attributes.Contains("crmn_ourdescription"))

{

try

{

Entity image = context.PostEntityImages["image"]; // Change the PreEntityImages as PostEntityImages and register post image "image" with related plugin step

Entity contactTemp = new Entity(entity.LogicalName);

contactTemp.Id = entity.Id;

int kundelikes = image.GetAttributeValue<int>("new_kundelikes");

String forsteVurdering = image.FormattedValues["new_frstegangsvurdering"].ToString();

int score = kundelikes * 100;

contactTemp.Attributes["description"] = score.ToString();

client.Update(entity);

}

catch (Exception ex)

{

throw new InvalidPluginExecutionException("Howdy! An error occured in the plugin:", ex);

}

}

}

else return;

}

}

}

}
