I manage a PostgreSQL database and am working on a tool for users to access a subset of the database. The database has a number of columns, and in addition we use a huge number of hstore keys to store additional information specific to certain rows in the database. Basic example below

You can use .str.extractall() to extract the keys and values from column hstore, then use .pivot() to transform the keys to column labels. Aggregate the entries for each row in original dataframe by .groupby() and .agg(). Set NaN for empty entries with .replace(). Finally, join back the result dataframe to original dataframe with .join():

From looking at the expected type for the Options object passed to report.generate, I can see that the type which they expect for theme is a union of string literals.

Your theme 'bootstrap' is one of those options, but in the error message you can see that typescript interpreted it as string instead of the literal string 'bootstrap'. You can use as const so that typescript sees it as a literal:

Goal - creating middleware-like callback in userHandler in util.js util.js for some express routes in express app, generated with express-generator and sequlize-cli.

Expected - user model successfully used in routes and userHandler in util.js.

ANSWER

Answered 2021-Jan-18 at 14:30

Problem found - unclear circular dependency

utils.js requires models/index.js

models/index.js not directly requires models/user.js

models/user.js requires utils.js, more exactly - signToken function from it

What was done - renamed utils.js in routeUtils.js, put signToken and verifyToken functions to new file tokenUtils.js, updated imports in other files, so this circular dependency will not happen, after this, it imported correctly.

Main updates:

Editing the pg_hba.conf in the default postgres:12 docker image

Asked 2021-Jan-17 at 06:37

I'm trying to enable streaming replication in the standard postgres:12 docker image, this requires changes to pg_hba.conf. I've managed to update the postgresql.conf via forcibly making the database use it (passing the the -c config_file="<>" flag in docker-compose rather through init scripts).

But I cannot find a parameter or flag option to get the database to use my pg_hba.conf despite trying to do so in startup scripts copied to docker-entrypoint-initdb.d.

Any ideas?

Answered 2021-Jan-17 at 05:19

You can specify a custom pg_hba.conf location by editing/including the hba_file parameter in postgresql.conf. From the documentation:

If you switched a data type from INTEGER to UUID you shouldn't try to convert UUID-string to a number doing where: { userId: +userId }.
