QUESTION
I tried to update part of a document that has an array. I hear this is a big no-no in mongoose but am unaware how I can force it to update the array. It does it correctly in the code (as in, it updates the value in the locally fetched document,) but when I try to save it via await mongoUser.save()
, it is not updated in mongo.
Here is my schema code
...ANSWER
Answered 2021-Dec-21 at 04:20I believe the reason the array is not getting saved is because the type of the guildScores
field is Array
. In the documentation of the Array
schema type, it says that specifying just Array
is equivalent to Mixed
. The documentation for the Mixed
schema type states:
Since Mixed is a schema-less type, you can change the value to anything else you like, but Mongoose loses the ability to auto detect and save those changes. To tell Mongoose that the value of a Mixed type has changed, you need to call doc.markModified(path), passing the path to the Mixed type you just changed.
To avoid these side-effects, a Subdocument path may be used instead.
QUESTION
I have an Angular service that uses AngularFire's auth observable to listen to state changes of the user. When a user signs in, the app must fetch a user document from MongoDB. This data needs to be consumable by components, so I need to have another observable. The problem is, I'm not quite sure how to make it work.
Here is a snippet of my auth service.
...ANSWER
Answered 2021-May-26 at 18:54By reassigning to this._mongoUser
, you are throwing away all of the subscriptions that were made before the reassignment.
To avoid reassignment, you can use a Subject
or BehaviorSubject
. In this case, I think BehaviorSubject
would be a better fit. It keeps track of the most recently emitted item and
- re-emits that item to new subscribers
- lets you synchronously access that item with the
BehaviorSubject#getValue
method
Here is a version of your example that is modified to use BehaviorSubject
.
QUESTION
I have the following two files and I'm trying to setup authentication but the incoming request comes up as undefined when I try to pass it through a function.
The code block
console.log(req.params)
Actually gives back the expected results, so if I were to send a request of...
http://localhost:5000/register/banana/john
...it would return
{ user: 'banana', password: 'john' }
but the following
await mongoUser.register(user, password);
I get
TypeError: Cannot read property 'toBSON' of undefined
If this happens to be a typescript specific problem, I apologize in advanced. I'm transitioning over from js so it's possible I'm not specifying a type somewhere.
index.ts
...ANSWER
Answered 2021-Mar-12 at 23:56Hm, the first thing I notice is that in the first snippet in the await mongoUser.register(username, password); //error within
line you use username
as variable, whereas above you only defined user
and password
..
Might this be the problem?

Update:It is not just the Admin role which is not working - it seems any route which required authorisation is returning a 401.
I want to create an admin role to control access to my AdminController. My stack is MongoDb/.NET Core(3.1) for the API/ Angular 9 front end.
I seed my database with the roles
...ANSWER
Answered 2020-Nov-16 at 20:08It turns out it was just stupidity which caused this error. I'd hardcoded in the issuer and JWT key variables of the Register/Login end point, and I'd wrote them in incorrectly.
Because they then didn't match with the issuer/jwt key in the startup.cs file(see below)...

I have a connection string where I want to reference a dynamic password variable that changes based on environment. I've set this prefix as part of my script so it exists as variable environment
