pass extra parameters to breeze-saving-server functions

Currently, I am working on a project using Durandal. In order to retrieve and save data, I am using Breeze. However, I am facing an issue where I need to send additional parameters to the server when saving, such as the user who is saving the entity. The saveChanges function of Breeze only accepts one parameter - an entities array for saving.

Is there a workaround for this situation?

Answer №1

To utilize the SaveOptions.tag feature, the code would look something similar to the following example:

var options = new SaveOptions({ name: "SaveWithNote", tag: "Data of your choice" });
return myEntityManager.saveChanges(null, options);

The 'tag' attribute can be accessed on the server side within the ContextProvider, as demonstrated in this snippet:

// Inside the ContextProvider on the server side
protected override bool BeforeSaveEntity(EntityInfo entityInfo) {
   var tagData = (string)SaveOptions.Tag;
   ...

}
