How to search for values in TinyDB

Question

I would like to search my database for a value. I know you can do this for a key with db.search() but there does not seem to be any kind of similar function for searching for a value

I've tried using the contains() function but I have the same issue. It checks if the key is contained in the database. I would like to know if a certain value is contained in the database.

I would like to do something like this that would search for values in tinydb

db.search('value')

If I was able to execute the above command and get the value(if it does exist) or Nothing if it doesn't that would be ideal. Alternatively, if the able returned True or False accordingly, that would be fine as well

Answer 1

I don't know if this is what you are looking for but which the following command you can check for a specific field value:

from tinydb import Query
User = Query()
db.search(User.field_name == 'value')

Answer 2

I'm new here (doing some reading to see if TinyDB would even be applicable for my use case) so perhaps wrong, and also aware that this question is a little old. But I wonder if you can't address this by iterating over each field and searching within for your value. Then, you couldget the key or field wherein a value match was located.
