flask.Config.from_json

Config.from_json(filename, silent=False)[source]

Updates the values in the config from a JSON file. This function behaves as if the JSON object was a dictionary and passed to the from_mapping() function.

Parameters:
  • filename – the filename of the JSON file. This can either be an absolute filename or a filename relative to the root path.
  • silent – set to True if you want silent failure for missing files.

New in version 0.11.
