I have a problem with mongoose. Please help me. I need to write a function that inserts email and a user name into the Mongo database. If an email is already present in the database, then it updates the respective email's user name with the new user name. I found a way to do this operation in MongoDB ( db.onlyInsertIfValueIsUniqueDemo.update ) but I don't have any idea how to do it with Mongoose. Please help me solve this problem.

In react application I used a form to inserted data and with express JS I post this data to mongo db.
when people is logged in the can insert data using form. and there is a page where user can view and delete their inserted data. Problem is how can I load data that was inserted by specific user?
When any user log in and user insert data also store user_id with
every entry. Now get data from DB by using current user logged in
user_id and display that specific data on front end. That's it.
Comment below for any query.
Thanks
Im very new to Android development. At the moment I am trying to develop my first app. My app is going to have a friend-system. Im trying to setup the Firestore-database to match my conditions.
I want to use the UserID provided by the google authentication to control the access of the database.
Every user has a friendlist of usernames,since I think, its not safe to let any client know the UserID of another client.
My Firestore database looks like this:
"users" (collection)
UserID (document)
DisplayName, Username (fields)
"friendlist"
UserID
Username1,Username2,Username3...
Everytime I want to access data of a user inside my friendlist a have to retrieve data from the users-collection using the UserID-document. Since the client isnt allowed to know the UserID of the friend, I need another collection which I am planing to access through cloud functions to know which userID belongs to the username.
"usernames" (collection)
Username (document)
UserID (fields)
Is there a better way to minimize database-reads while protecting database accesses?
You could try looking for the UserID(document) based on the Username filed taking the answer from this other thread as a starting point.
Nevertheless, you would need to make sure that the Usernames do not repeat as this may cause issues later on by programming a check in the insertion of updates of usernames.
Otherwise, the solution you are planning would work although with the caveat that you may get a higher billing in the future as you are billed for every read as mentioned here.
Hope you find this useful!
I want to check the username and password is existed in mysql DB table and provide result ("existed" or "Notexisted"). Please provide the full solution to this as i am a beginner in Django.
I already connected to the mysqldb . but i don't know how the structure should
Thanks in advance.
I can access a logged in user with $this->Auth->user(); in the controllers. That’s so far clear.
If I add some new DB field in the users table, clear the cake cache and logs in again then still I can not find the new field in the returned user record with $this->Auth->user(). This field is also missing in the session file on the server. What is it which I am missing?
For an application I am writing, I need to know where some of the settings in the Admin Panel are being stored in a table on the database. Specifically, if one is logged into the Admin Panel, under System->Configuration->Contacts->Email Options, there are three select boxes "Send Emails To", "Email Sender" and "Email Template".
I can't seem to find what table the currently selected options are stored in. I want to do this since I am creating a transactional email via install script (I was able to find that transactional emails are stored under core_email_template), and would like it to be selected by default via my install script along with the default email being changed.I assumed that the currently selected options are somewhere on the database, I just can't seem to find where for the life of me!
I was hoping that someone would know where these settings were stored, or if someone could share some strategies to find out which table(s) hold information like this.
Thank you for any help you can offer.
It is in the core_config_data table
