SyncDataLoader

✓ from graphql_sync_dataloaders import SyncDataLoader

✗ from graphql_sync_dataloaders.decorators import SyncDataLoader

SyncDataLoader is directly exposed from the top-level package, not a submodule.

Example using SyncDataLoader with Django ORM. batch_load_fn must return a list of results parallel to keys.

from graphql_sync_dataloaders import SyncDataLoader class UserLoader(SyncDataLoader): def batch_load_fn(self, keys): # keys is a list of user IDs; return list of users in same order users = {user.id: user for user in User.objects.filter(id__in=keys)} return [users.get(key) for key in keys] loader = UserLoader() user = loader.load(1) # Synchronous call users = loader.load_many([1, 2, 3])

Debug

Known issues

gotchaSyncDataLoader.batch_load_fn must return a list of values in the exact same order as the input keys. Returning a dict and mapping may produce incorrect order.

fix

Always ensure batch_load_fn returns a list parallel to keys, using list comprehension or similar.

affects: >=0.1.0

deprecatedThe package has no known deprecations, but it is a very small library with low activity. Check for updates before relying on it for critical production systems.

fix

Monitor the GitHub repository for new releases or consider contributing fixes.

affects: >=0.1.0

Errors

Common errors & fixes

ImportError: cannot import name 'SyncDataLoader' from 'graphql_sync_dataloaders'

Incorrect import path or outdated version; SyncDataLoader is available from version 0.1.0 onwards.

fix

Upgrade to latest version: pip install --upgrade graphql-sync-dataloaders. Then import: from graphql_sync_dataloaders import SyncDataLoader

TypeError: batch_load_fn() missing 1 required positional argument: 'keys'

The batch_load_fn method signature expects exactly one argument (keys), but the class may not be properly subclassed or the method is defined incorrectly.

fix

Define batch_load_fn(self, keys) as a method of your subclass. Example: class MyLoader(SyncDataLoader):
    def batch_load_fn(self, keys):
        return [...]
