``Argenta`` в рантайме вызывает исключения в пограничных случаях пользовательского ввода.

Все исключения обрабатываются системными хэндлерами, но у вас есть возможность их переопределить. Переопределение осуществляется

Incorrect flag syntax: <raw input command>
|

|
||||
Для переопределения стандартного поведения используется сеттер ``.set_incorrect_input_syntax_handler(_: NonStandardBehaviorHandler[str])``,
|
||||
протокол ``NonStandardBehaviorHandler[str]`` соответствует ``Callable[[str], None]``, то есть хэндлер должен быть вызываемым объектом,
|
||||
к примеру функция или лямбда, которая принимает единственный аргумент - строку, которая представляет собой необработанную введённую команду, и ничего не возвращает.
|
||||
|
||||
This error means that one of the objects cannot be created because some of
|
||||
its dependencies depend on itself.

Repeated input flags: <raw input command>
|
||||
|
||||
Для переопределения стандартного поведения используется сеттер ``.set_repeated_input_flags_handler(_: NonStandardBehaviorHandler[str])``,
|
||||
протокол ``NonStandardBehaviorHandler[str]`` соответствует ``Callable[[str], None]``, то есть хэндлер должен быть вызываемым объектом,
|
||||
к примеру функция или лямбда, которая принимает единственный аргумент - строку, которая представляет собой необработанную введённую команду, и ничего не возвращает.

``EmptyInputCommandException``: Введена пустая команда
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
* **Factory is simply missing.**
|
||||
Check that you added all required providers and they contain appropriate ``provide``.
|
||||
Исключение вызывается, когда пользователь вводит команду в виде строки из пробельных символов - ``\n``, ``\t``, пробел и т.д.
|
||||
|
||||
* **Context data is not marked with from_context**
|
||||
Check that you added all required providers and they contain appropriate ``from_context``.
|
||||
Дефолтный хэндлер выводит в консоль
|
||||
|
||||
* **Object has invalid scope**
|
||||
Check the scope of provided type and the types dependent on it.
|
||||
Note, that long-living objects cannot depend on short-living ones.
|
||||
E.g. object with ``Scope.APP`` cannot depend on one with ``Scope.REQUEST``.
|
||||
.. code-block:: shell
|
||||
|
||||
You should review used scopes.
|
||||
Empty input command
|
||||
|
||||
Для переопределения стандартного поведения используется сеттер ``.set_empty_command_handler(_: EmptyCommandHandler)``,
|
||||
протокол ``EmptyCommandHandler`` соответствует ``Callable[[], None]``, то есть хэндлер должен быть вызываемым объектом,
|
||||
к примеру функция или лямбда, которая не принимает аргументов и ничего не возвращает.
|
||||
|
||||
* **Object is provided in another component**
|
||||
Components are isolated and cannot implicitly share objects.
|
||||
You should either use ``FromComponent`` to call another component directly or
|
||||
create object separately for appropriate component using ``provide`` annotation

||||

|

|
||||
* **Dependency is parent class while provided child class (or vice versa)**
|
||||
Use ``provides=`` argument to mark that source and provided types are different.
|
||||
Use ``WithParents[X]`` to provide an object as its type with parent classes

``UnknownCommandException``: Введена неизвестная команда
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Исключение вызывается, когда пользователь вводит команду, которая не зарегистрирована ни в одном роутере и не является алиасом ни для
|
||||
одной зарегистрированной команды.

CannotUseProtocolError: Cannot use ... as a factory

dishka.provider.exceptions.CannotUseProtocolError: Cannot use <class '__main__.SomeProtocol'> as a factory.
|
||||
Tip: seems that this is a Protocol. Please subclass it and provide the subclass.
|
||||
Unknown command: <trigger of the input command>
|
||||
|
||||
Для переопределения стандартного поведения используется сеттер ``.set_unknown_command_handler(_: NonStandardBehaviorHandler[InputCommand])``,
|
||||
протокол ``NonStandardBehaviorHandler[InputCommand]`` соответствует ``Callable[[InputCommand], None]``, то есть хэндлер должен быть вызываемым объектом,
|
||||
к примеру функция или лямбда, которая принимает обязательный аргумент типа :ref:`InputCommand <input_command>` и ничего не возвращает.
|
||||
|
||||
This error means that you used some protocol class as a source argument of ``provide`` function.
|
||||
Protocols cannot be instantiated.
|
||||
Check that you have an implementation for that protocol, and use it.
|
||||
You can try using the form ``provide(YourImpl, provides=YourProtocol)``.

|

|

.. code-block::
|
||||
|
||||
dishka.provider.exceptions.NotAFactoryError: Cannot use typing.Union[int, str] as a factory.
|
||||
|
||||
|
||||
Check what are you passing to ``provide`` function. Probably that object cannot be instantiated directly.
|
||||
|
||||
Note, that you can provide some type by creating an instance of another one using the form ``provide(YourClass, provides=SomeTypeHint)``.

ImplicitOverrideDetectedError: Detected multiple factories for ...
|

-------------------------------------------------------------------------
|

|

.. code-block::
|
||||
|
||||
dishka.exceptions.ImplicitOverrideDetectedError: Detected multiple factories for (<class '__main__.A'>, component='') while `override` flag is not set.
|
||||
Hint:
|
||||
* Try specifying `override=True` for SecondProvider.get_a
|
||||
* Try removing factory FirstProvider.get_a or SecondProvider.get_a
|
||||
|
||||
This error can be seen only if you enabled ``implicit_override=True`` in validation settings.
|
||||
It means that you have 2 factories for the same type without specifying that the second one should replace the first one.
|
||||
|
||||
* **You meant to have one of factories**. Just remove the second one.
|
||||
|
||||
* **You want to override dependency for tests or other purposes**. Specify ``override=True`` when creating second factory.
|
||||
|
||||
Error text will contain details on both option with names of providers.
|
||||
|
||||
|
||||
NothingOverriddenError: Overriding factory found for ..., but there is nothing to override.
|
||||
---------------------------------------------------------------------------------------------------
|
||||
|
||||
.. code-block::
|
||||
|
||||
dishka.exceptions.NothingOverriddenError: Overriding factory found for (<class '__main__.A'>, component=''), but there is nothing to override.
|
||||
Hint:
|
||||
* Try removing override=True from FirstProvider.get_a
|
||||
* Check the order of providers
|
||||
|
||||
This error can be seen only if you enabled ``nothing_overridden=True`` in validation settings.
|
||||
That means you set ``override=True``, but there is no second factory to be overriden or the order of providers is incorrect.
|
||||
|
||||
Check, that you have specified all expected providers in correct order or remove the flag.
|
||||
|
||||
|
||||
IndependentDecoratorError: Decorator ... does not depend on provided type.
|
||||
---------------------------------------------------------------------------------------------------
|
||||
|
||||
.. code-block::
|
||||
|
||||
dishka.provider.exceptions.IndependentDecoratorError: Decorator __main__.FirstProvider.get_a does not depend on provided type.
|
||||
Did you mean @provide instead of @decorate?
|
||||
|
||||
Using ``decorate`` is a special case if you need to apply decorator patter or do modifications with an object created in another provider.
|
||||
Is requests an object of some type (additional dependencies are allowed) and returns the same type.
|
||||
|
||||
If you are not going to use an object received from another factory, probably you meant to use simple ``provide`` instead?
