Approvals
Describes the process of creating a content approval.
IApprovalRepository
is the base interface for saving, deleting and listing approvals and their decisions. IApprovalEngine
is built on top of IApprovalRepository
to streamline the handling of approvals. Use the repository for listing approvals and use the engine for handling approvals. The engine also raises events that can be hooked up in IApprovalEngineEvents
.
Hook up events
[InitializableModule]
public class ApprovalLogger : IInitializableModule
{
private IApprovalEngineEvents _approvalEngineEvents;
public void Initialize(InitializationEngine context)
{
_approvalEngineEvents = context.Locate.Advanced.GetInstance<IApprovalEngineEvents>();
_approvalEngineEvents.Approved += OnApproved;
}
public void Uninitialize(InitializationEngine context) => _approvalEngineEvents.Approved -= OnApproved;
private void OnApproved(ApprovalEventArgs e) => LogManager.GetLogger(typeof(ApprovalLogger)).Debug("Approve");
}
Start an Approval
A content approval is not started by saving an approval but by saving a content item with SaveAction.RequestApproval
. This automatically creates and saves a ContentApproval
for this content item, if a definition can be resolved.
IContent content;
IContentRepository contentRepository;
var approvalContentLink = contentRepository.Save(content, SaveAction.RequestApproval);
Abort an approval
This deletes an approval and raises an aborted event:
Approval approval;
IApprovalEngine approvalEngine;
await approvalEngine.AbortAsync(approval.ID, "user");
Make a decision
Use the engine to decide to approve or reject a step or the whole approval. There is a possibility to add an optional comment to explain the reason for the decision. If the decision finishes the approval (approves the last step or rejects a step), this comment is saved on the approval as CompletedComment
.
Approval approval;
IApprovalEngine approvalEngine;
// Approve a step if user is part of the current definition step
await approvalEngine.ApproveAsync(approval.ID, "user", 1, ApprovalDecisionScope.Step);
// Reject a step if user is part of the current definition step, adding a comment
await approvalEngine.RejectAsync(approval.ID, "user", 1, ApprovalDecisionScope.Step, "This is why I did it");
// Force approve a step whether the user is part of the current definition step or not
await approvalEngine.ApproveAsync(approval.ID, "user", 1, ApprovalDecisionScope.ForceStep);
// Force approve the whole approval
await approvalEngine.ApproveAsync(approval.ID, "user", 1, ApprovalDecisionScope.Force);
There are also a number of more explicitly named extension methods to the engine that can be used, for example ApproveStepAsync
and ForceApproveAsync
.
List approvals
Use the GetAsync
/ GetItemsAsync
methods on IApprovalRepository
to get specific approvals using ID or ContentReference
:
using EPiServer.Approvals.ContentApprovals;
ContentReference contentLink;
IApprovalRepository approvalRepository;
var approval = await approvalRepository.GetAsync(contentLink);
The ListAsync
method takes an ApprovalQuery
/ ContentApprovalQuery
object which searches the approvals based on the specified query-data and returns a filtered list. This list can be paged.
This example gets all approvals in review for a user based on a specific definition.
using EPiServer.Approvals.ContentApprovals;
ContentApprovalDefinition definition;
IApprovalRepository approvalRepository;
var approvals = await approvalRepository.ListAsync(new ContentApprovalQuery
{
Username = "user",
Status = ApprovalStatus.InReview,
DefinitionID = definition.ID
});
This example list decisions made for an approval:
Approval approval;
IApprovalRepository approvalRepository;
var decisions = await approvalRepository.ListDecisionsAsync(approval.ID);
