QUESTION
Can someone please point to me what part of this code is causing an infinite loop? I have tried wrapping this in useCallback as well but it still runs forever.
- slug is the page url that will not change over time
- likesCollectionRef is also goint to remain constant
- isAuth can change overtime depending on if the user is logged in or out
ANSWER
Answered 2022-Mar-04 at 21:42likesCollectionRef
is declared each render cycle. Place the likes collection reference in a React ref so it's a stable reference. auth
also appears to be an external dependency. If it's external to the component this is ok, but if it's internal to the component it should be added to the dependency array.
QUESTION
I have airflow dag written to work with Python operator.I need to use PostgreSQL operator for same dag without changing functionality of dag. Here is code with Python operators. How Should I replace Python operator with PostgreSQL operator? Or can we use two different operators in a single dag?
...ANSWER

runs SQL. Your code is querying API, generate a CSV and loading it to the DB. You can not do that with PostgesOperator
.
What you can do is to replace the usage of psycopg2
with PostgresHook
.
The hook is a wrapper around psycopg2
that expose you functions that you can interact with. This means that, for example, you don't need to handle how to connect to Postgres on your own. Simply define the connection in Admin -> Connections
and reference the connection name in the hook:

QUESTION
I'm working with MongoDB's Realm cloud computing service.
As the title suggests, the query runs fine in the console, but not when executed externally (through Postman).
Key Points:
- When logged, the moviesList is empty when externally triggered, but has data when in console.
- I have set up a default rule for the collection providing read/write access.
- It returns empty results externally, no errors caught.
ANSWER
Answered 2022-Jan-20 at 07:34It looks like it was a permissions issue to the database.
The console was obviously providing me with root permissions, so it was working.
The API was failing, but no errors (as far as I could tell) were being thrown. It just returned an empty set.
QUESTION
I have a pretty simple system of 2 views in SQLite DB and 2 tableViews in Desktop Qt Widget Application:
- First view is 'seller_view' and it is just printed in App's tableView correctly via QSqlTableModel.
- Second is 'customer_view' (setup is the same as above) and it does not print any data, but shows model's headers, that was set up in constructor.
So, we got a strange situation when:
SQL View data in SQLiteStudio (view 'customer_view')

a try: just use it instead of QSqlTableModel

See "history diffing" in simple_history docs:
https://django-simple-history.readthedocs.io/en/latest/history_diffing.html
I have this all working, but it states:
"diff_against also accepts 2 arguments excluded_fields and included_fields to either explicitly include or exclude fields from being diffed."
