QUESTION
I am developing inventory management software. The database uses RLS to allow multiple clients using the same database. As such every table has a "Client ID" column. When inventory is scanned, it updates the numbers for "active", "reserved" or "incoming" states.
Active = ready to use, Reserved = temporarily reserved as an order is potentially incoming (but may be cancelled) and Incoming = ordered stock
These states are adjusted at various points - sales, good received, stock count updates etc. I want to know how best to avoid data inconsistencies. What I want to do is basically tell postgres "lock this table for client X with rows matching SKU XXX while I run this entire transaction" but I can't figure out how to do it.
...ANSWER
Answered 2022-Mar-30 at 00:40It sounds like you need a table of customer/SKU combinations, and then everyone who does the things that need to be serialized must lock the relevant row in that table first. Or if you don't want to permanently enumerate all possible client/SKU combinations, you could do it on the fly:
QUESTION
Is a query allowed only when the user has been granted access, and the data returned is the subset that RLS permits?
...ANSWER
Answered 2022-Mar-28 at 07:04Permissions regulate which databases, schemas, tables and table column a user can access. Row level security adds additional conditions to each statement that determine which rows a user can see or modify.
QUESTION
I am building Web API backend for multitenant, .NET 6 based, application and I have encountered an architectural problem which drives me crazy since last couple of weeks, so I would much appreciate ANY hints and advices.
Whole solution is build in classic Clean Architecture (layers: API, Domain, Application, Infrastructure, Shared), which was't the greatest idea I suppose, but I'm affraid it is irreversible by now. Anyway, I would like to make an effort to save all I have created so far.
In the application I have 2 databases (with Entity Framework in the code behind):
Database A: Tenant users scope - with TenantId field in each table for RLS mechanizm implemented on the SQL level to prevent inter-tenant data leaks
Database B: Internal users scope - no RLS mechanism
The problem is both databases share great amount of common structures and logic.
Simplified example of current models (both database and domain):
Database A:
ANSWER
Answered 2022-Mar-23 at 11:06This way I'm creating a lot of code duplication. I do not want to create common interfaces for those classes because I think this may kill the application's development in some point in the future (Models may become a little bit different anytime).
If you have too much duplication, you are right in thinking you should merge your code. If both model should be able to have common code, and specific code, then the solution to your problem is probably polymorphism.
I would suggest to have two new classes Domain.TenantEmployee
and Domain.InternalEmployee
both inheriting from an abstract Domain.Employee
. You can put common behavior in the parent class, and specific one in the child ones.
Then your infrastructure layer can convert Domain.TenantEmployee
from/to DatabaseA.TenantEmployee
and Domain.InternalEmployee
from/to DatabaseB.InternalEmployee
.

QUESTION
I want to run llvm-slicer
(source) for PostgreSQL main executable file (i.e., PG_ROOT/src/backend/postgres
) to carry backward slicing on PostgreSQL.
llvm-slicer
runs on top of bitcode (.bc
file). I have compiled PostgreSQL via ./configure CC=clang-6.0 && make CC=clang-6.0
, duiring which, the final compile command that link many .o
files together is (very long):
ANSWER
Answered 2022-Mar-22 at 08:54Solution: whole-program-llvm.
It provides tools for building whole-program (or whole-library) LLVM bitcode files from an unmodified C or C++ source package. It currently runs on *nix platforms such as Linux, FreeBSD, and Mac OS X.
QUESTION
I am trying to make an input form where the user can change several values in one row simultaneously which get submitted to the database using the update()
method. The values are being read from the Supabase Table into several input fields as defaultValues, which the user can edit and later submit form to update values in the Supabase instance of the table.
The input values received from user are stored in a object that has the shape :
...ANSWER
Answered 2022-Mar-21 at 10:04It looks like your match
filter doesn't work.
I would suggest trying to match row by its ID since you want to update only one row. This way you are actually trying to update all rows that match this data, and that might be causing an issue. I am not sure if we can batch update like this with supabase at the moment.
This is something I'm using in my apps whenever I want to update data for a single row, and I don't have any issues with it. I would suggest to try this, if the question is still relevant. 😊
await supabase.from("company").update(inputFields).match({ id: company.id });
or
await supabase.from("company").update(inputFields).eq("id", company.id)
You could also pass only new values to .update()
so you don't update whole row, but only data that has been changed.

I have built a small ontology in Protege to test punning with a SPARQL query. The Ontology is:
...ANSWER
Answered 2022-Mar-11 at 14:06Harry is a GE, from your assertions. GE is both a class and an individual; so GE appears in other statements as well, and that's multiplying the answers you're seeing. It's analogous as joining across tables where the join value matches multiple rows in one of the tables involved.

I am working on a container to run TensorFlow Serving.
Here is my Dockerfile
:
ANSWER
Answered 2022-Mar-09 at 06:51https://www.tensorflow.org/tfx/serving/docker
Optional environment variable MODEL_NAME (defaults to model)
Optional environment variable MODEL_BASE_PATH (defaults to /models)
You are using default values of these env variables, so Tensorflow is trying to find model in /models/model
. You have different model path in the container, so /models/model not found
is correct.
I would say simple configuration of MODEL_NAME
env variable should solve the problem:
QUESTION
I am trying to read several .RLS (spreadsheet) files into one matrix using R. These files have very formulaic names, which makes it easy to work with. My plan (see code below) is to create the file names in a vector called names, then use a for loop to read and add the second column of each of those files into a matrix. However, I have encountered some issue. I have tested the names part of my code, and it can read tables into R individually. However when I try to put them all together into the matrix collected using the 2nd for loop, I get an error that says, "incorrect number of subscripts on matrix". I am not sure what this means. Any advice would be welcome.
...ANSWER
Answered 2022-Mar-01 at 19:51Regarding the issue, it may be because we used read_table
which returns a tibble
and tibble doesn't drop dimensions with [
. Instead, we need [[
.
QUESTION
I'm having a problem saving a report across different workspaces in PowerBI embedded. For background:
- We're using PowerBI embedded in an App Owns Data scenario
- We're operating a SaaS, multi-tenanted single database approach where we're segregating tenant data in PowerBI using RLS
- We're using a singular dataset that will be shared across multiple workspaces (which I believe is supported in V2 workspaces according to Microsoft documentation)
- The scopes for the Service Principal are defined correctly and we have a dedicated capacity purchased & configured
- We're using .NET6 and PowerBI embedded is being displayed in a Razor view.
If I use the built in PowerBI save functionality, it always saves to the workspace where the dataset resides (and it works perfectly fine, which makes be believe the issue is not down to the EmbedToken being generated which is why I've omitted it here).
I've implemented functionality in the Razor View as per below (based on the official Microsoft documentation) to save the report to a defined workspace using the targetWorkspaceId defined in the saveAsParameters.
...ANSWER
Answered 2022-Feb-18 at 11:46Thanks to Andrey for pointing me to the documentation. The issue was I was using GenerateTokenRequest within the C# SDK whereas I should have been using GenerateTokenRequestV2. Working code is below.
