Each time a user follows or unfollows four different actions are run for both the functionality.
Let's say, for the following feature, I have the below code,

So you can do something like:

I was working on a leetcode question where we need to design the basic twitter functionality , such as follow and unfollow , post a tweet and newsfeed which will give the most recent 10 tweets for a user
postTweet(userId, tweetId): Compose a new tweet. getNewsFeed(userId): Retrieve the 10 most recent tweet ids in the user's news feed. Each item in the news feed must be posted by users who the user followed or by the user herself. Tweets must be ordered from most recent to least recent. follow(followerId, followeeId): Follower follows a followee. unfollow(followerId, followeeId): Follower unfollows a followee.

QUESTION
In my app, when user unfollows another user I want the corresponding follow notification to be deleted from firebase. But when I'm updating the reference of that notification the observe function gets triggered immediately and the new notification gets deleted.
So how can i -if there is a way- update notification value without triggering observer function?
Below are my functions of uploading notifications and deleting them "Follow notifications"
...ANSWER
Answered 2020-Aug-07 at 15:44It's not possible to make a database observer completely ignore a specific update. You will either have to remove the observer entirely, or write some code in it that decides if it should take action when it's been invoked.

Meditate on this as a starting point for how to learn it. It'll also show a simple, but not the most efficient, way to do what you're asking about:
QUESTION
I am attempting to create a method by which a user may attach related records to an existing records similar to how a user may follow other users. However, when the method is called, a relationship can only be made between the record and itself. I have based my code on a follower/following model and I believe the issue is arising because the method is unable to differentiate between the current record and the record being selected to create a relationship with. Any ideas how this may be addressed? Relevant code is below...
Model
...ANSWER
Answered 2019-May-14 at 03:11I found that the issue outlined above arose due to a child not being defined in the child-parent relationship between two records in the self referential relationship. by adding the following lines in the form and controller respectively I was able to define this variable and create the desired relationships.

QUESTION
I am creating a recurring event app where certain users (streamers) can schedule recurring weekly events (streams) and other users (viewers) can follow them. The result is a personalized weekly calendar detailing when all followed streamers' events begin and end.
However, because viewers can follow an infinite number of streamers and therefore the resulting calendar would look like a hot mess. So I added a boolean attribute to the relationships table that indicates whether the relationship has been favorited.
...ANSWER
Answered 2019-Jan-19 at 23:32The first comment on this answer is correct, so I don't know why this person posted as a comment rather than an answer. update_attribute takes two arguments and you are passing it a single hash argument. Your "favorite" method is the equivalent of
update_attribute({favorited: true})
when you really want update_attribute(:favorited, true)
