Exemplo: Associar e desassociar registros usando o ponto de extremidade OData com JavaScript

Artigo
07/06/2017

Publicado: novembro de 2016

Aplicável a: Dynamics CRM 2015

Este código de exemplo é para o Atualização do Microsoft Dynamics CRM 2015 e Microsoft Dynamics CRM Online 2015.Baixe o pacote do SDK do Microsoft Dynamics CRM. Pode ser encontrado no seguinte local no pacote de download:

SampleCode\JS\RESTEndpoint\JavaScriptRESTAssociateDisassociate

Se você só deseja ver como esse exemplo funciona, é possível instalar (importar) a solução gerenciada JavaScriptRESTAssociateDisassociateSample_1_0_0_2_managed.zip incluída nos arquivos de download. Se você instalar esta solução gerenciada e deseja criar os recursos da Web usando os nomes descritos neste tópico, o prefixo de personalização do fornecedor de soluções não pode ser “sample”, a menos que você desinstale (exclua) a solução gerenciada.

Requisitos

Para executar o código de exemplo, crie os seguintes recursos da Web:

sample_/JavaScriptRESTAssociateDisassociate.htm
Uma página HTML que fornece a interface com o usuário para executar os exemplos.
sample_/Scripts/JavaScriptRESTAssociateDisassociate.js
Uma biblioteca de JavaScript que contém funções para gerenciar a interface com o usuário.
sample_/Scripts/SDK.REST.js
Essa biblioteca do JavaScript fornece as funções SDK.REST.associateRecords e SDK.REST.disassociateRecords, além de outras funções para uso do ponto de extremidade REST para recursos da Web.

Observação

O prefixo de personalização ‘sample_’ não é usado no código. Esses exemplos funcionarão usando o prefixo de personalização de qualquer editor. No entanto, o caminho relativo da pasta Scripts simulada deve ser incluído no nome dos recursos da Web.

Demonstra

Essa amostra contém dois exemplos:

Associar contas
Esse exemplo cria dois novos registros de conta e os associa. As etapas a seguir descrevem as ações:
1. Crie um novo registro de conta chamado “Conta primária”.
2. Crie um novo registro de conta chamado “Conta secundária”.
3. Associe os registros, configurando a conta primária como a principal da conta secundária.
4. Exiba os links para permitir verificar se a associação foi executada.
5. Exiba os botões para permitir desassociar e excluir os registros criados pelo exemplo.
Associar conta para email como ActivityParty
Este exemplo cria um registro account e email e associa à conta para o email como o campo from usando um registro activityparty. As etapas a seguir descrevem as ações:
1. Crie um novo registro de conta chamado “Conta do remetente do email”.
2. Criar uma nova atividade de email chamada “Atividade de email”.
3. Crie um novo registro de activityparty que associe a conta ao email.
4. Exiba os links para permitir a exclusão dos registros.
5. Exiba um botão para permitir a exclusão do registro.

Ambos os exemplos possuem um botão para iniciar o exemplo. Os resultados são exibidos na seção Resultados na parte inferior da página. Após a execução de um dos exemplos, use o botão de Amostra REST para executar o exemplo novamente.

Esse arquivo fornece a UI que explica os comportamento de exemplo e os botões para iniciar e redefinir os exemplos.
