Création d'attributs

Créez des attributs en définissant un des types AttributeMetadata, puis en le passant au message CreateAttributeRequest.

L’exemple suivant définit AttributeMetadata pour un certain nombre de différents types d’attributs et les ajoute à List<AttributeMetadata>. À la fin du code les définitions d’attribut sont transmises à une instance de la classe CreateAttributeRequest et l’attribut est créé en utilisant la méthode Execute.

L’exemple suivant suppose que le préfixe de personnalisation actuel est « nouveau » car il s’agit du préfixe de personnalisation par défaut pour l’éditeur de solutions de l’organisation. Vous devez utiliser le préfixe de personnalisation de l’éditeur de solutions pertinent pour le contexte de solution.

Récupérer un attribut

Cet exemple montre comment récupérer AttributeMetadata pour un attribut à l’aide de RetrieveAttributeRequest. Cet exemple récupère les métadonnées pour un attribut StringAttributeMetadata personnalisé appelé « new_string » de l’entité Contact qui a été créée dans Création d'attributs.

Notes

Dans la mesure où RetrieveAsIfPublished correspond à la valeur true, cette demande retourne la définition non publiée actuelle de cet attribut. Vous pouvez utiliser cette option si vous créez un éditeur d’attributs et si vous souhaitez récupérer la définition non publiée de l’attribut. Sinon, vous ne devez pas spécifier RetrieveAsIfPublished.Pour plus d'informations :Récupération des métadonnées non publiées


// Create the request
RetrieveAttributeRequest attributeRequest = new RetrieveAttributeRequest
{
    EntityLogicalName = Contact.EntityLogicalName,
    LogicalName = "new_string",
    RetrieveAsIfPublished = true
};

// Execute the request
RetrieveAttributeResponse attributeResponse =
    (RetrieveAttributeResponse)_serviceProxy.Execute(attributeRequest);

Console.WriteLine("Retrieved the attribute {0}.",
    attributeResponse.AttributeMetadata.SchemaName);


' Create the request
Dim attributeRequest As RetrieveAttributeRequest = New RetrieveAttributeRequest With {
 .EntityLogicalName = Contact.EntityLogicalName,
 .LogicalName = "new_string",
 .RetrieveAsIfPublished = True}

' Execute the request
Dim attributeResponse As RetrieveAttributeResponse = CType(_serviceProxy.Execute(attributeRequest), RetrieveAttributeResponse)

Console.WriteLine("Retrieved the attribute {0}.", attributeResponse.AttributeMetadata.SchemaName)

Mettre à jour un attribut

Cet exemple illustre comment mettre un attribut à jour. Cet exemple utilise la UpdateAttributeRequest pour modifier la propriété AttributeMetadata.DisplayName d’un attribut personnalisé récupéré précédemment pour l’entité Contact.


// Modify the retrieved attribute
AttributeMetadata retrievedAttributeMetadata =
    attributeResponse.AttributeMetadata;
retrievedAttributeMetadata.DisplayName =
    new Label("Update String Attribute", _languageCode);

// Update an attribute retrieved via RetrieveAttributeRequest
UpdateAttributeRequest updateRequest = new UpdateAttributeRequest
{
    Attribute = retrievedAttributeMetadata,
    EntityName = Contact.EntityLogicalName,
    MergeLabels = false
};

// Execute the request
_serviceProxy.Execute(updateRequest);

Console.WriteLine("Updated the attribute {0}.",
    retrievedAttributeMetadata.SchemaName);


' Modify the retrieved attribute
Dim retrievedAttributeMetadata As AttributeMetadata = attributeResponse.AttributeMetadata
retrievedAttributeMetadata.DisplayName = New Label("Update String Attribute", _languageCode)

' Update an attribute retrieved via RetrieveAttributeRequest
Dim updateRequest As UpdateAttributeRequest = New UpdateAttributeRequest With {
 .Attribute = retrievedAttributeMetadata,
 .EntityName = Contact.EntityLogicalName,
 .MergeLabels = False}

' Execute the request
_serviceProxy.Execute(updateRequest)

Console.WriteLine("Updated the attribute {0}.", retrievedAttributeMetadata.SchemaName)

Créer un attribut de recherche

Cet exemple montre comment créer un attribut de recherche.

Un attribut de recherche est créé en utilisant CreateOneToManyRequest.


CreateOneToManyRequest req = new CreateOneToManyRequest()
{
 Lookup = new LookupAttributeMetadata()
 {
  Description = new Label("The owner of the bank account", 1033),
  DisplayName = new Label("Account Owner", 1033),
  LogicalName = "new_parent_contactid",
  SchemaName = "New_Parent_ContactId",
  RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.ApplicationRequired)
 },
 OneToManyRelationship = new OneToManyRelationshipMetadata()
 {
  AssociatedMenuConfiguration = new AssociatedMenuConfiguration()
  {
   Behavior = AssociatedMenuBehavior.UseCollectionName,
   Group = AssociatedMenuGroup.Details,
   Label = new Label("Bank Accounts", 1033),
   Order = 10000
  },
  CascadeConfiguration = new CascadeConfiguration()
  {
   Assign = CascadeType.Cascade,
   Delete = CascadeType.Cascade,
   Merge = CascadeType.Cascade,
   Reparent = CascadeType.Cascade,
   Share = CascadeType.Cascade,
   Unshare = CascadeType.Cascade
  },
  ReferencedEntity = Contact.EntityLogicalName,
  ReferencedAttribute = "contactid",
  ReferencingEntity = _customEntityName,
  SchemaName = "new_contact_new_bankaccount"
 }
};
_serviceProxy.Execute(req);


Dim req As New CreateOneToManyRequest() With {
 .Lookup = New LookupAttributeMetadata() With {
  .Description = New Label("The owner of the bank account", 1033),
  .DisplayName = New Label("Account Owner", 1033),
  .LogicalName = "new_parent_contactid",
  .SchemaName = "New_Parent_ContactId",
  .RequiredLevel = New AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.ApplicationRequired)},
 .OneToManyRelationship = New OneToManyRelationshipMetadata() With {
  .AssociatedMenuConfiguration = New AssociatedMenuConfiguration() With {
   .Behavior = AssociatedMenuBehavior.UseCollectionName,
   .Group = AssociatedMenuGroup.Details,
   .Label = New Label("Bank Accounts", 1033),
   .Order = 10000},
  .CascadeConfiguration = New CascadeConfiguration() With {
   .Assign = CascadeType.Cascade,
   .Delete = CascadeType.Cascade,
   .Merge = CascadeType.Cascade,
   .Reparent = CascadeType.Cascade,
   .Share = CascadeType.Cascade,
   .Unshare = CascadeType.Cascade},
  .ReferencedEntity = Contact.EntityLogicalName,
  .ReferencedAttribute = "contactid",
  .ReferencingEntity = _customEntityName,
  .SchemaName = "new_contact_new_bankaccount"
 }
}
_serviceProxy.Execute(req)

Créer une liste déroulante qui utilise un groupe d’options général

Cet exemple montre comment créer un attribut PicklistAttributeMetadata qui est associé à un groupe d’options général.

L’exemple suivant utilise CreateAttributeRequest pour définir les options d’un attribut PicklistAttributeMetadata afin d’utiliser un groupe d’options général avec un nom représenté par la variable de chaîne _globalOptionSetName.Pour plus d'informations :Personnaliser les groupes d’options généraux


// Create a Picklist linked to the option set.
// Specify which entity will own the picklist, and create it.
CreateAttributeRequest createRequest = new CreateAttributeRequest
{
    EntityName = Contact.EntityLogicalName,
    Attribute = new PicklistAttributeMetadata
    {
        SchemaName = "sample_examplepicklist",
        LogicalName = "sample_examplepicklist",
        DisplayName = new Label("Example Picklist", _languageCode),
        RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),

        // In order to relate the picklist to the global option set, be sure
        // to specify the two attributes below appropriately.
        // Failing to do so will lead to errors.
        OptionSet = new OptionSetMetadata
        {
            IsGlobal = true,
            Name = _globalOptionSetName
        }
    }
};

_serviceProxy.Execute(createRequest);


' Create a Picklist linked to the option set.
' Specify which entity will own the picklist, and create it.
Dim createRequest As CreateAttributeRequest = New CreateAttributeRequest With {
 .EntityName = Contact.EntityLogicalName,
 .Attribute = New PicklistAttributeMetadata With {
  .SchemaName = "sample_examplepicklist", .LogicalName = "sample_examplepicklist",
  .DisplayName = New Label("Example Picklist", _languageCode),
  .RequiredLevel = New AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
  .OptionSet = New OptionSetMetadata With {
   .IsGlobal = True,
   .Name = _globalOptionSetName
  }
 }
}
' In order to relate the picklist to the global option set, be sure
' to specify the two attributes below appropriately.
' Failing to do so will lead to errors.

_serviceProxy.Execute(createRequest)

Insérer une nouvelle valeur de statut

Cet exemple montre comment insérer une nouvelle option Raison du statut pour l’attribut StatusAttributeMetadata.

L’exemple suivant utilise la InsertStatusValueRequest pour spécifier une nouvelle option pour l’attribut Contact.StatusCode de l’entité Contact qui n’est pas valide lorsque Contact.StateCode correspond à 0 (Actif). La méthode IOrganizationService.Execute traite la demande.

L’exemple suivant permet d’utiliser deux options Raison du statut valides pour les contacts actifs : Actif et Dormant.


// Use InsertStatusValueRequest message to insert a new status 
// in an existing status attribute. 
// Create the request.
InsertStatusValueRequest insertStatusValueRequest =
    new InsertStatusValueRequest
{
    AttributeLogicalName = "statuscode",
    EntityLogicalName = Contact.EntityLogicalName,
    Label = new Label("Dormant", _languageCode),
    StateCode = 0
};

// Execute the request and store newly inserted value 
// for cleanup, used later part of this sample. 
_insertedStatusValue = ((InsertStatusValueResponse)_serviceProxy.Execute(
    insertStatusValueRequest)).NewOptionValue;

Console.WriteLine("Created {0} with the value of {1}.",
    insertStatusValueRequest.Label.LocalizedLabels[0].Label,
    _insertedStatusValue);


' Use InsertStatusValueRequest message to insert a new status 
' in an existing status attribute. 
' Create the request.
Dim insertStatusValueRequest As InsertStatusValueRequest = New InsertStatusValueRequest With {
 .AttributeLogicalName = "statuscode",
 .EntityLogicalName = Contact.EntityLogicalName,
 .Label = New Label("Dormant", _languageCode),
 .StateCode = 0}

' Execute the request and store newly inserted value 
' for cleanup, used later part of this sample. 
_insertedStatusValue = (CType(_serviceProxy.Execute(insertStatusValueRequest), InsertStatusValueResponse)).NewOptionValue

Console.WriteLine("Created {0} with the value of {1}.", insertStatusValueRequest.Label.LocalizedLabels(0).Label, _insertedStatusValue)

Mettre à jour une valeur d’état

Cet exemple montre comment modifier l’étiquette d’une option dans un attribut StateAttributeMetadata.

L’exemple suivant utilise UpdateStateValueRequest pour modifier l’étiquette d’option Contact.StateCodeActif en Ouvert.


// Modify the state value label from Active to Open.
// Create the request.
UpdateStateValueRequest updateStateValue = new UpdateStateValueRequest
{
    AttributeLogicalName = "statecode",
    EntityLogicalName = Contact.EntityLogicalName,
    Value = 1,
    Label = new Label("Open", _languageCode)
};

// Execute the request.
_serviceProxy.Execute(updateStateValue);

Console.WriteLine(
    "Updated {0} state attribute of {1} entity from 'Active' to '{2}'.",
    updateStateValue.AttributeLogicalName,
    updateStateValue.EntityLogicalName,
    updateStateValue.Label.LocalizedLabels[0].Label
    );


' Modify the state value label from Active to Open.
' Create the request.
Dim updateStateValue As UpdateStateValueRequest = New UpdateStateValueRequest With {
 .AttributeLogicalName = "statecode",
 .EntityLogicalName = Contact.EntityLogicalName,
 .Value = 1,
 .Label = New Label("Open", _languageCode)}

' Execute the request.
_serviceProxy.Execute(updateStateValue)

Console.WriteLine("Updated {0} state attribute of {1} entity from 'Active' to '{2}'.",
                  updateStateValue.AttributeLogicalName,
                  updateStateValue.EntityLogicalName,
                  updateStateValue.Label.LocalizedLabels(0).Label)

Vous ne pouvez ajouter ni supprimer des options StateCode, mais vous pouvez modifier les étiquettes des options.

Insérer une nouvelle option dans un groupe d’options général local

Cet exemple montre comment ajouter une nouvelle option à un groupe d’options local. L’exemple suivant utilise InsertOptionValueRequest pour ajouter une nouvelle option à un attribut personnalisé PicklistAttributeMetadata pour l’entité Contact.


// Create a request.
InsertOptionValueRequest insertOptionValueRequest =
    new InsertOptionValueRequest
{
    AttributeLogicalName = "new_picklist",
    EntityLogicalName = Contact.EntityLogicalName,
    Label = new Label("New Picklist Label", _languageCode)
};

// Execute the request.
int insertOptionValue = ((InsertOptionValueResponse)_serviceProxy.Execute(
    insertOptionValueRequest)).NewOptionValue;

Console.WriteLine("Created {0} with the value of {1}.",
    insertOptionValueRequest.Label.LocalizedLabels[0].Label,
    insertOptionValue);


' Create a request.
Dim insertOptionValueRequest As InsertOptionValueRequest = New InsertOptionValueRequest With {
 .AttributeLogicalName = "new_picklist",
 .EntityLogicalName = Contact.EntityLogicalName,
 .Label = New Label("New Picklist Label", _languageCode)}

' Execute the request.
Dim insertOptionValue As Integer = (CType(_serviceProxy.Execute(insertOptionValueRequest), InsertOptionValueResponse)).NewOptionValue

Console.WriteLine("Created {0} with the value of {1}.", insertOptionValueRequest.Label.LocalizedLabels(0).Label, insertOptionValue)

Modifier l’ordre des options dans le groupe d’options local

Cet exemple montre comment modifier l’ordre des options dans le groupe d’options local. L’exemple suivant extrait un attribut PicklistAttributeMetadata personnalisé et change l’ordre des options d’origine à l’aide de la fonction LINQOrderBy pour trier des éléments dans l’ordre croissant en fonction du libellé de l’étiquette. Ensuite, il utilise OrderOptionRequest pour définir le nouvel ordre des options de l’attribut.

Utilisez la fonction LINQ OrderByDecending pour trier les éléments dans l’ordre décroissant.


// Use the RetrieveAttributeRequest message to retrieve  
// a attribute by it's logical name.
RetrieveAttributeRequest retrieveAttributeRequest =
    new RetrieveAttributeRequest
{
    EntityLogicalName = Contact.EntityLogicalName,
    LogicalName = "new_picklist",
    RetrieveAsIfPublished = true
};

// Execute the request.
RetrieveAttributeResponse retrieveAttributeResponse =
    (RetrieveAttributeResponse)_serviceProxy.Execute(
    retrieveAttributeRequest);

// Access the retrieved attribute.
PicklistAttributeMetadata retrievedPicklistAttributeMetadata =
    (PicklistAttributeMetadata)
    retrieveAttributeResponse.AttributeMetadata;

// Get the current options list for the retrieved attribute.
OptionMetadata[] optionList =
    retrievedPicklistAttributeMetadata.OptionSet.Options.ToArray();

// Change the order of the original option's list.
// Use the OrderBy (OrderByDescending) linq function to sort options in  
// ascending (descending) order according to label text.
// For ascending order use this:
var updateOptionList =
    optionList.OrderBy(x => x.Label.LocalizedLabels[0].Label).ToList();

// For descending order use this:
// var updateOptionList =
//      optionList.OrderByDescending(
//      x => x.Label.LocalizedLabels[0].Label).ToList();

// Create the request.
OrderOptionRequest orderOptionRequest = new OrderOptionRequest
{
    // Set the properties for the request.
    AttributeLogicalName = "new_picklist",
    EntityLogicalName = Contact.EntityLogicalName,
    // Set the changed order using Select linq function 
    // to get only values in an array from the changed option list.
    Values = updateOptionList.Select(x => x.Value.Value).ToArray()
};

// Execute the request
_serviceProxy.Execute(orderOptionRequest);

Console.WriteLine("Option Set option order changed");


' Use the RetrieveAttributeRequest message to retrieve  
' a attribute by it's logical name.
Dim retrieveAttributeRequest As RetrieveAttributeRequest = New RetrieveAttributeRequest With {

Supprimer un attribut

Cet exemple montre comment supprimer les attributs stockés dans les List<AttributeMetadata> qui ont été créées pour l’entité Contact dans Création d'attributs. Pour chaque AttributeMetadata, la DeleteAttributeRequest prépare la demande qui est traitée à l’aide de IOrganizationService.Execute.


// Delete all attributes created for this sample.
foreach (AttributeMetadata anAttribute in addedAttributes)
{
    // Create the request object
    DeleteAttributeRequest deleteAttribute = new DeleteAttributeRequest
    {
        // Set the request properties 
        EntityLogicalName = Contact.EntityLogicalName,
        LogicalName = anAttribute.SchemaName
    };
    // Execute the request
    _serviceProxy.Execute(deleteAttribute);
}


' Delete all attributes created for this sample.
For Each anAttribute As AttributeMetadata In addedAttributes
 ' Create the request object
 Dim deleteAttribute As DeleteAttributeRequest = New DeleteAttributeRequest With {
  .EntityLogicalName = Contact.EntityLogicalName,
  .LogicalName = anAttribute.SchemaName}
 ' Set the request properties 
 ' Execute the request
 _serviceProxy.Execute(deleteAttribute)
Next anAttribute
