在预定义的时间内禁止特定 firebase firestore 群聊中的用户

Question

I am very new to coding. but i managed to build a group chat app using a low code platform called flutterflow. i managed to spend significant amount of time on it and was able to build a public group chat app except few functionalities. I am hoping to find help from here. for the following questions.

1. I have chat mods appointed on a group level. like if you create a group, you are a founder and you can assign mods to that perticular group chat. now i want these mods to be able to ban a user in that particular group chat.

I have tried created a subcollection in groups called "banned user" and created two feilds. one is "banned users" document reference to users. and another is "banned_till" to record a time stamp until the user gets banned.

Problem with this is when i ban a user twice, it creates two documents in the user reference with the same user. and two documents has different "banned_till" times. which one it is supposed to pick?

i tried to do this and put a conditional visibility to the chat that "if current time is less than or equal to banned_till time" it wont let user type in the textfield to chat. but this is giving me gray screen.

I am very new to this. any help would be appreciated.

Answer 1

there is specific way to do so. you have to set custom logic. like save all banned users in a firebase database object with thier max time and procced next.
