Error when loading database file

When using the example code in Python 3.8 i get this error :

Traceback (most recent call last):
  File "C:/Users/loicn/backend_db.py", line 7, in <module>
    db = connection.my_tiny_database

    return TinyMongoDatabase(name, self._foldername, self._storage)

I have used this extensively-- so I have a high level of confidence it works and will continue to work even if Schapman upgrades the code.

Make sure you are importing tinymongo and tinydb. In this case we are “overriding” the TinyMongoClient class property import to ensure we have the correct return. It might look a little awkward, but it achieves the same effect as Conner Boyle’s fork (Thank you David Lai for pointing this out)

######### code starts here import tinymongo as tm import tinydb class TinyMongoClient(tm.TinyMongoClient): @property def _storage(self): return tinydb.storages.JSONStorage ############ code ends here

ALTERNATELY… You could just work with the forked version from Conner Boyle’s github repository.

$ pip uninstall tinymongo $ pip install git+https://github.com/cjboyle/tinymongo

The only “gotcha” of doing it this way is that you cannot uninstall CJBoyle’s version with a “pip uninstall”, you have to remove it the old fashioned way of going into the environment packages and deleting the directory.

I actually got this on 3.7.6 The class TinyMongoClient(tm.TinyMongoClient) solution didn’t seem to work for me, but I can’t 100% ensure that I didn’t mess something else up 😃

How would one support custom serialization such as the DateTimeSerializer provided with tinymongo using this work around? The suggested method of supporting datetime objects in tinymongo already overrides this property:

import tinydb
from tinydb_serialization import SerializationMiddleware
import tinymongo as tm

class TinyMongoClient(tm.TinyMongoClient):
    @property
    def _storage(self):
        serialization = SerializationMiddleware()
        serialization.register_serializer(tm.serializers.DateTimeSerializer(), 'TinyDate')
        return serialization
