QUESTION
I'm using a user-friendly json based document oriented database named TinyDB. But I'm unable to add multiple pieces of data to my database because I'm making use of multiproccesing. After a while I get the error that id x already exists in the database (this because 2 or more processes are trying to add data at the same time). Is there any way to solve this?
Every run I insert new unique params.
Example params:
...ANSWER
Answered 2021-Apr-17 at 16:23If you want to parallelize the data write, you need to break your problem down into smaller steps so that you can ensure the step where you're inserting data has already coalesced everything together. That way you won't have any (obvious) thread safety issues on the write.
For example, suppose your JSON file has three fields, email, name, and age and you want to enforce uniqueness on email, but some records are double-entered. E.g., there's one entry that has emily@smith.com with her name, and another with her age.
You'd start by making something to group everything together, then parallelize the write.
I'll sketch some code (note I have not tested this!):

For my app I need values which are parsed by jSoup from a website and then returned to the user using a notification, these values change ~ every minute, so to be up-todate with the values I set up a task using a handler, this works good when the app is in foreground, but as soon as the user goes to the homescreen the app will return multiple exceptions like e.g. java.net.UnknownHostException or java.net.SocketTimeoutException, in the code this happens when jSoup is connecting to the specified site, I already tried using Services and AsyncTasks instead of threads, but it was always the exact same problem, I also searched for people with similar experiences, but I guess my issue is quite specific.
This is the code for the handler:

...ANSWER
Answered 2021-Mar-09 at 19:11You are getting the TypeError because your Result is a list of dictionaries.
Make sure to iterate through Result and process each dictionary separately.
Your Result object is like this [{}, {}, {} ...]
Also you shouldn't capitalize the first letter of your variable. You should name it results, because it may contain more than 1 result.

QUESTION
I have a tinydb json file but I noticed that at a certain point it refuses to write more items to the json file and throws an error while parsing because it cut off in the middle of writing an item
This is the traceback. It shows the json parser failing to parse because the writer cut off writing in the middle of an item
...ANSWER
Answered 2021-Feb-11 at 11:14The reason this happened was because multiple threads were writing to the db file at the same time so I ended up manually writing to multiple files: one for every entry

I am trying to have a login system where user input will be crosschecked with tinydb's json file. I managed to get the registration working but when I try logging in I got this error.
TypeError: unsupported operand type(s) for &: 'list' and 'QueryInstance'
I tried removing password verification and it worked. Not entirely sure the reason behind it. Would be great if I can receive some guidance as to what went wrong. Thanks!
...ANSWER
Answered 2020-Dec-30 at 23:11It should have been and not &. The operand and will check both the conditions that you are trying to validate whereas & does a bitwise AND and it doesn't like the types of data provided for the bitwise AND, hence the error.
