1. В редаксе у leverages должен быть тип например {[key: string]: Leverage}, где в key хранится symbol.
Тогда в LeverageForm можно передать только symbol и index. Доставать данные уже внутри LeverageForm по symbol:
const leverages = useSelector((state: AppState) => state.leverageSlice.leverages[symbol]);
Тогда LeverageForm будет ререндериться только при изменении плеча по его монете.
2. changed можно сделать свойством объекта Leverage.
3. LeverageForm у нас отрисовывает 223 раза, потому что в LeveragePage 223 symbols. Нужно сделать так, чтобы когда менялся один из объектов по leverage state.leverage[symbol], он изменлся, а остальные 22 символа не изменялись и LeverageForm не перерисовывался, а перерисовывался только там где я меняю данные.
То есть должна быть оптимизация

Когда я вызываю задачи

Как я должен изменить данный код?
Есть два класса:
from sqlalchemy.orm import subqueryload,load_only
tasks_topics = db.Table('tasks_topics',
db.Column('task_id', db.Integer, db.ForeignKey('tasks.id')),
db.Column('topics_id', db.Integer, db.ForeignKey('topics.id'))
)
class Tasks(db.Model):
__tablename__ = 'tasks'
__searchable__ = ['task', 'id'] # these fields will be indexed by whoosh
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
url = db.Column(db.String(120), comment="ЧПУ задачи в адресе (транслитом)")
task = db.Column(db.Text, comment='Условие задачи')
answer = db.Column(db.Text, comment='Ответ')
status = db.Column(db.Boolean, default=0, comment='Статус: опубликована/неактивна (по умолчанию нет)')
created_t = db.Column(db.DateTime, comment='Дата и время создания')
level = db.Column(db.SmallInteger, default=1, comment='Уровень сложности: 1,2 ... (по умолчанию 1 уровень)')
# связи
topics = db.relationship('Topics',
secondary=tasks_topics,
back_populates="tasks")
class Topics(db.Model):
__tablename__ = 'topics'
__searchable__ = ['name']
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
name = db.Column(db.String(140), comment="Уникальное название темы(подтемы)")
parent = db.Column(db.Integer, default=0, comment="ID родительской темы(если есть)")
# связи
tasks = db.relationship('Tasks',
secondary=tasks_topics,
back_populates="topics")
def return_parent_as_class(self):
cte = Topics.query.filter(Topics.id == self.id).cte(name="parents", recursive=True)
# Определяем рекурсивную часть CTE
cte = cte.union_all(Topics.query.join(cte, cte.c.parent == Topics.id))
# Выполняем запрос, используя рекурсивную CTE
parent_topics = Topics.query.from_statement(cte.select().order_by(cte.c.parent)).all()
return parent_topics
Когда я вызываю задачи
all_tasks =Tasks.query.options(subqueryload(Tasks.topics)).filter(Tasks.id.in_([6,14])).all()
for task in all_tasks:
print(task.topics)
я получаю
[<Topics 17>, <Topics 18>, <Topics 16>]
[<Topics 13>, <Topics 18>]
Однако это далеко не все родительские топики. Полный результат должен быть
[<Topics 1>,<Topics 4>,<Topics 16>, <Topics 17>, <Topics 18>]
[<Topics 1>,<Topics 3>,<Topics 13>, <Topics 18>]
Как получить все родительные топики?

Есть два класса:
from sqlalchemy.orm import subqueryload,load_only
tasks_topics = db.Table('tasks_topics',
db.Column('task_id', db.Integer, db.ForeignKey('tasks.id')),
db.Column('topics_id', db.Integer, db.ForeignKey('topics.id'))
)
class Tasks(db.Model):
__tablename__ = 'tasks'
__searchable__ = ['task', 'id'] # these fields will be indexed by whoosh
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
url = db.Column(db.String(120), comment="ЧПУ задачи в адресе (транслитом)")
task = db.Column(db.Text, comment='Условие задачи')
answer = db.Column(db.Text, comment='Ответ')
status = db.Column(db.Boolean, default=0, comment='Статус: опубликована/неактивна (по умолчанию нет)')
created_t = db.Column(db.DateTime, comment='Дата и время создания')
level = db.Column(db.SmallInteger, default=1, comment='Уровень сложности: 1,2 ... (по умолчанию 1 уровень)')
# связи
topics = db.relationship('Topics',
secondary=tasks_topics,
back_populates="tasks")
class Topics(db.Model):
__tablename__ = 'topics'
__searchable__ = ['name']
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
name = db.Column(db.String(140), comment="Уникальное название темы(подтемы)")
parent = db.Column(db.Integer, default=0, comment="ID родительской темы(если есть)")
# связи
tasks = db.relationship('Tasks',
secondary=tasks_topics,
back_populates="topics")
def return_parent_as_class(self):
cte = Topics.query.filter(Topics.id == self.id).cte(name="parents", recursive=True)
# Определяем рекурсивную часть CTE
cte = cte.union_all(Topics.query.join(cte, cte.c.parent == Topics.id))
# Выполняем запрос, используя рекурсивную CTE
parent_topics = Topics.query.from_statement(cte.select().order_by(cte.c.parent)).all()
return parent_topics
Когда я вызываю задачи
all_tasks =Tasks.query.options(subqueryload(Tasks.topics)).filter(Tasks.id.in_([6,14])).all()
for task in all_tasks:
print(task.topics)
я получаю
[<Topics 17>, <Topics 18>, <Topics 16>]
[<Topics 13>, <Topics 18>]
Однако это далеко не все родительские топики. Полный результат должен быть
[<Topics 1>,<Topics 4>,<Topics 16>, <Topics 17>, <Topics 18>]
[<Topics 1>,<Topics 3>,<Topics 13>, <Topics 18>]
Как мне надо изменить all_tasks =Tasks.query.options(subqueryload(Tasks.topics)).filter(Tasks.id.in_([6,14])).all()
Данный код (или может быть в другом месте) чтобы при вызове топиков для каждой задачи я получал бы все родительские топики?

Есть два класса:
from sqlalchemy.orm import subqueryload,load_only
tasks_topics = db.Table('tasks_topics',
db.Column('task_id', db.Integer, db.ForeignKey('tasks.id')),
db.Column('topics_id', db.Integer, db.ForeignKey('topics.id'))
)
class Tasks(db.Model):
__tablename__ = 'tasks'
__searchable__ = ['task', 'id'] # these fields will be indexed by whoosh
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
url = db.Column(db.String(120), comment="ЧПУ задачи в адресе (транслитом)")
task = db.Column(db.Text, comment='Условие задачи')
answer = db.Column(db.Text, comment='Ответ')
status = db.Column(db.Boolean, default=0, comment='Статус: опубликована/неактивна (по умолчанию нет)')
created_t = db.Column(db.DateTime, comment='Дата и время создания')
level = db.Column(db.SmallInteger, default=1, comment='Уровень сложности: 1,2 ... (по умолчанию 1 уровень)')
# связи
topics = db.relationship('Topics',
secondary=tasks_topics,
back_populates="tasks")
class Topics(db.Model):
__tablename__ = 'topics'
__searchable__ = ['name']
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
name = db.Column(db.String(140), comment="Уникальное название темы(подтемы)")
parent = db.Column(db.Integer, default=0, comment="ID родительской темы(если есть)")
# связи
tasks = db.relationship('Tasks',
secondary=tasks_topics,
back_populates="topics")
Когда я вызываю задачи
all_tasks =Tasks.query.options(subqueryload(Tasks.topics)).filter(Tasks.id.in_([6,14])).all()
ТО, что я хочу получить в sql запросе
WITH RECURSIVE topic_parent(id, path) AS (
SELECT
id, ARRAY[id]
FROM topics
WHERE parent = 0
UNION
SELECT
t.id, path || t.id
FROM
topics t
INNER JOIN topic_parent rt ON rt.id = t.parent
),
cte2 as (
select *, unnest(path) AS linked_id
from topic_parent
)
select task_id, max(task) as task_name, max(name) as topic_name, linked_id as topic_id
from cte2 c
inner join tasks_topics t on c.id = t.topics_id
inner join tasks t2 on t2.id = t.task_id
inner join topics t3 on t3.id = c.linked_id
group by task_id, linked_id
order by task_id asc, linked_id desc
Как мне надо исправить свой код?

Есть два класса:
from sqlalchemy.orm import subqueryload,load_only
tasks_topics = db.Table(‘tasks_topics’,
db.Column(‘task_id’, db.Integer, db.ForeignKey(‘tasks.id’)),
db.Column(‘topics_id’, db.Integer, db.ForeignKey(‘topics.id’))
)
class Tasks(db.Model):
tablename = ‘tasks’
searchable = [‘task’, ‘id’] # these fields will be indexed by whoosh
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
url = db.Column(db.String(120), comment=“ЧПУ задачи в адресе (транслитом)”)
task = db.Column(db.Text, comment=‘Условие задачи’)
answer = db.Column(db.Text, comment=‘Ответ’)
status = db.Column(db.Boolean, default=0, comment=‘Статус: опубликована/неактивна (по умолчанию нет)’)
created_t = db.Column(db.DateTime, comment=‘Дата и время создания’)
level = db.Column(db.SmallInteger, default=1, comment=‘Уровень сложности: 1,2 … (по умолчанию 1 уровень)’)
# связи
topics = db.relationship(‘Topics’,
secondary=tasks_topics,
back_populates=“tasks”)
class Topics(db.Model):
tablename = ‘topics’
searchable = [‘name’]
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
name = db.Column(db.String(140), comment=“Уникальное название темы(подтемы)”)
parent = db.Column(db.Integer, default=0, comment=“ID родительской темы(если есть)”)
# связи
tasks = db.relationship(‘Tasks’,
secondary=tasks_topics,
back_populates=“topics”)
Когда я вызываю задачи
all_tasks =Tasks.query.options(subqueryload(Tasks.topics)).filter(Tasks.id.in_([6,14])).all()
ТО, что я хочу получить в sql запросе
WITH RECURSIVE topic_parent(id, path) AS (
SELECT
id, ARRAY[id]
FROM topics
WHERE parent = 0
UNION
SELECT
t.id, path || t.id
FROM
topics t
INNER JOIN topic_parent rt ON rt.id = t.parent
),
cte2 as (
select *, unnest(path) AS linked_id
from topic_parent
)
select task_id, max(task) as task_name, max(name) as topic_name, linked_id as topic_id
from cte2 c
inner join tasks_topics t on c.id = t.topics_id
inner join tasks t2 on t2.id = t.task_id
inner join topics t3 on t3.id = c.linked_id
group by task_id, linked_id
order by task_id asc, linked_id desc
Как мне надо исправить свой код? Код нужно написать без использования raw sql

Let's make a test. Create two vectors of the same size, but one is of strings and the other is of strings views. Fill both with random letters but both vectors should contain the same thing. Then iterate through them in range loop and measure the time it took. Use const reference as an iterator

Я написал файл RNN.py который обучается предсказывать числа.
Суть вот в чём: у меня есть файл numbers.json который содержит в себе следующие значения {"numbers": ["2.44x", "8.14x", "1.79x", "59.34x"]} самое новое с лева, эти значения подгружаются в этот файл на лету, каждый раз обновляя этот файл, примерно в среднем через 8 секунд +/-.
Мой скрипт RNN.py по идее должен делать следующее:
Считывать значения из этого файла и обучаться предсказывать следующее значение "показывая его мне в консоли".
Приведу пример того как это должно происходить:
Вот у нас сейчас есть эти значения в файле numbers.json {"numbers": ["2.44x", "8.14x", "1.79x", "59.34x"]} скрипт должен угадать следующее значение и показать мне его в консоли, после чего ждать появления результата в самом начале, в файле numbers.json например так {"numbers": ["4.33x", "2.44x", "8.14x", "1.79x", "59.34x"]}, если результат RNN который он вывел мне в консоль оказался не верным, он должен скорректировать себя там обучится, понять, что не верный результат показал или не совсем точный близкий к тому который появился в файле numbers.json и предугадать следующий результат до того как он появится в файле numbers.json, предугадать вывести его опять-же мне в консоль и ожидать результата в файле numbers.json для того что-бы свериться, был-ли угадан результат или нет. И так до тех пор пока я сам не остановлю работу скрипта!
Вот мой скрипт RNN.py тебе нужно его исправить он не работает должным образом!
