Patch Request - Remove from array

[Paul Hinett]

How can I do a patch request to remove a certain element from an array, I know you can do it by position but I won’t know what the position is.

 

It’s a simple IList<string>, I know the string to pass in.

With the current patching API you can't do this, you have to tell it where in the array you want to make the change.

You'll have to Load the doc, modify it in the client and then Store it again after.

No, you have to do this manually

I assume that would be the case for updating arrays as well, correct? I have a user document with a Roles array on it that I want to update if the role name changes. Do I need to just load each user, find the role, change it, and store it for each user? Or is there a way to use the patching API for this?

Here's my user document:

{

name: "username",

...,

roles: [

{id:"roles/1",name:"role1"},

{id:"roles/2",name:"role2"}

]

}

I'm only just getting started with Raven, so let me know if I'm structuring this wrong.

Isn't there a unit test for this in RavenDB?

  [Fact]
  public void RemoveItemFromArrayByValue()
  {
   var patchedDoc = new JsonPatcher(RavenJObject.Parse(@"{ name: ""Joe Doe"", roles: [""first/role"", ""second/role"", ""third/role""] }")).Apply(
    new[]
    {
     new PatchRequest
     {
      Type = PatchCommandType.Remove,
      Name = "roles",
      Value = "second/role"
     },
    });

   Assert.Equal(@"{""name"":""Joe Doe"",""roles"":[""first/role"",""third/role""]}",
       patchedDoc.ToString(Formatting.None));
  }

Um,yeah. I forgot about this :-)
