You can convert your User object to a Map and work as follow:

convert User to a Map original object
add all items to from userForm to original
convert the original to a User class
do what you need with the updated user

Basically the code is something like that:

You are violating the JPA spec by accessing the persistence context in a lifecycle listener.

See the JPA Specification 4.2 Section 3.5.2

In general, the lifecycle method of a portable application should not invoke EntityManager or query operations, access other entity instances, or modify relationships within the same persistence context. A lifecycle callback method may modify the non-relationship state of the entity on which it is invoked.

"a portable application should not" is the specification way of saying: Don't do that, anything might happen. Maybe the world ends.

The fix is not to do that. Maybe be preloading the currently logged in user and reference it so you may access it in your entity listener and do not set a reference to the user, but simple store its id or similar.

Snowflake DB Transfer to Postgres

Asked 2021-Jun-14 at 19:29

I'm trying to make a complete copy of a Snowflake DB into PostgreSQL DB (every table/view, every row). I don't know the best way to go about accomplishing this. I've tried using a package called pipelinewise , but I could not get the access needed to convert a snowflake view to a postgreSQL table (it needs a unique id). Long story short it just would not work for me.

I've now moved on to using the snowflake-sqlalchemy package. So, I'm wondering what is the best way to just make a complete copy of the entire DB. Is it necessary to make a model for each table, because this is a big DB? I'm new to SQL alchemy in general, so I don't know exactly where to start. My guess is with reflections , but when I try the example below I'm not getting any results.

This would be a perfect instance of when to use an annotation. You could define the annotation before the declaration of each class, indicating that the class has some meta-data about 'DALObjects'. Then you could use Reflections or some similar library to easily find all Class objects with this annotation.

For example;

Hide/show controllers in SwaggerUI (configurable)

Asked 2021-Jun-14 at 11:35

We would like SwaggerUI, which is being generated by Swashbuckle, to show all controllers and methods when debugging as well as on our test environment, but hide some on integration and production environments. Note that the hidden controllers/methods will be functional in all scenarios but won't be documented in SwaggerUI.

To do this I've applied the principal described here.

Which results in following code:

Type handler is not a good fit for your usage.
