kandi X-RAY | lerner Summary

lerner is a Python library typically used in Networking, Websocket applications. lerner has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Lerner is based around the concept of webhooks, push notifications sent via HTTP POST requests. Webhooks are great if you have a server that can accept POST requests, but what if you want to receive push notifications on a phone or a computer on a wifi connection. To receive push notifications under there conditions, you need to go beyond HTTP and use a protocol that supports persistent connections. Notistream achieves this using the Redis Pub/Sub protocol. A server, reimplementing Redis Pub/Sub, allows clients to open persistent connections and subscribe to channels. A webserver receives webhooks via POST requests and then publishes the information to the Pub/Sub server. Connected clients will then see the notification on their desktop/phone/whatever.

learnerRepository.save(learner); is returning the instance you are looking for.

learner = learnerRepository.save(learner); Now the id should be set correctly on learner.

QUESTION

sql.Identifier without quoting

Asked 2020-Jan-28 at 08:13

I did a web search for "sql.Identifier without quoting" and this post was relevant only. It advices to use .format(sql.Identifier.

However this method adds double quotes to identifiers and cannot as far as I can tell be used for identifiers made w/out quotes in PostgreSQL. As I've read in here expert advice not to quote identifiers in Postgres.

I do not see an option in sql.Identifier to skip quoting in the document and alternative methods in sql module of psycopg2. How can I use PostgreSQL from Python in injection-safe way for unquoted identifiers?

ADDED: my confusion was due to me using "public.abc" for sql.Identifier when as noted in the answer by @klin I should have used two identifiers. After that sorted out I see quoting is used only for case sensitive (and/or where "other" symbols like dot are used).

ANSWER

Answered 2020-Jan-28 at 06:58

If your database API routinely quotes identifiers, that is a good thing. Don't try hard to work around that.

The sentiment against quoted identifiers is not directed against the quoting as such, rather against the choice of idenifiers that require quoting.That are identifiers that do not follow the syntax rules for identifiers or contain upper case letters. Such identifiers cause all kinds of annoyances, for example in shell scripts, where quoting always is a nuisance.

Quoting an identifier that does not require quoting is innocuous, and it is actually a good safety measure.

The crux of this problem is the masking of all maskable columns for rows that fit some requirement. Supposing that I had a boolean series that told me which rows to mask (call it mask), I could use pandas.DataFrame.where to mask out where my mask is False. You can also pass a parameter to supply alternatives.

In this case, we are passing a pandas.Series with aligns with the DataFrame's index.

The rest of the functions are components to calculate OP's desired conditions.
