I am building REST API with PERN(postgres,express,react,node). I am trying to test my user registration route on postman and when I send the request I get this error. "database [my database name] does not exist"
I checked postgres server and i can clearly see i own the database and it is created. This is my connection.
const Pool = require("pg").Pool
const pool = new Pool({
host: "localhost",
user: "[myuser]",
password: "[mypassword]",
port: 5432,
database: "rental"
})
module.exports = pool;

I am currently trying to access cellular modem data from within a C application on Linux using mmlib-glib.
When trying to establish a GDBusConnection on a GFileIOStream created from a GFile from path /dev/cdc-wdm0, the call to g_dbus_connection_new_sync() hangs infinitely and gives the following error _g_dbus_worker_do_read_cb: error determining bytes needed: Unable to determine message blob length - given blob is malformed. Also, after this the modem will either become no longer available, or be kicked to a different modem number (i.e. org/freedesktop/ModemManager/Modem/2 will change to 3) I am constructing a GFile with the path /dev/cdc-wdm0, and from that initialize a GDBusConnection.
I have also tried initializing a new GIOStream and passing that to the mm_manager_scan_devices_sync() following instructions from this post but this results in the following errors :
g_dbus_connection_signal_subscribe: assertion 'sender == NULL || (g_dbus_is_name (sender) && (connection->flags & G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION))' failed
I have placed code below followed by mmcli output with modem information
#include <libmm-glib.h>
#include <gio/gio.h>
//#include <gtk/gtk.h>
#include <stdio.h>
#include <stdbool.h>
GDBusConnection *pConnection;
int main (void)
{
printf("begin\n");
GFile * pFile = g_file_new_for_path("/dev/cdc-wdm0");
GFileIOStream *pStream = g_file_open_readwrite(pFile, NULL, NULL);
pConnection= g_dbus_connection_new_sync(pStream,
guid, // for server auth.
G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION,
NULL, // observer
NULL, // cancellable,
NULL);
pManager = mm_manager_new_sync(pConnection,
G_DBUS_CONNECTION_FLAGS_MESSAGE_BUS_CONNECTION,
NULL,
NULL);
mm_manager_scan_devices_sync(pManager,
cancellable,
NULL);
printf("end\n");
return(0);
}
Below is the output from modemmanager mmcli --modem=0

I have following code to save to a local running mongo instance:
MongoCredential credential = MongoCredential.createCredential("myuser", "mydatabase", "mypassword".toCharArray());
MongoClient mongo = MongoClients.create(MongoClientSettings.builder()
.applyToClusterSettings(builder -> builder.hosts(Arrays.asList(new
ServerAddress("localhost", 27017))))
.credential(credential)
.build());
MongoDatabase database = mongo.getDatabase("mydatabase");
MongoCollection<Document> collection = database.getCollection("mycollection");
collection.insertOne(document);
I have created a user for usernmae/password used in code above using db.createUser() command in mongo.exe shell and these are same credentials I provided while installing mongodb.
db.createUser(
{ user: "myuser",
pwd: "mypassword",
roles:[{role: "userAdminAnyDatabase" , db:"admin"}]})
But code fails with:
Exception in thread "main" com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='myuser', source='mydatabase', password=<hidden>, mechanismProperties={}}
What am I missing here?
Where, i.e. in which database did you create the user? Typically users are created in database admin. When you connect to a MongoDB then you should always specify the authentication database and the database you like to use.
The defaults are a bit confusing and not really consistent, esp. different drivers/tools seem to behave different. See this table to get an overview:
+-------------------------------------------------------------------------------------+
|Connection parameters | Authentication | Current |
| | database | database |
+-------------------------------------------------------------------------------------+
|mongo -u user -p pwd --authenticationDatabase admin myDB | admin | myDB |
|mongo -u user -p pwd myDB | myDB | myDB |
|mongo -u user -p pwd --authenticationDatabase admin | admin | test |
|mongo -u user -p pwd --host localhost:27017 | admin | test |
|mongo -u user -p pwd | admin | test |
|mongo -u user -p pwd localhost:27017 | test | test |
|mongosh -u user -p pwd localhost:27017 | admin | test | -> Different on mongosh and legacy mongo shell
+-------------------------------------------------------------------------------------+
If you like to use Connection string in URI format, it would correspond to these ones. There it is more consistent and well documented.
+-------------------------------------------------------------------------------------+
|Connection string | Authentication | Current |
| | database | database |
+-------------------------------------------------------------------------------------+
|"mongodb://user:pwd#hostname/myDB?authSource=admin" | admin | myDB |
|"mongodb://user:pwd#hostname/myDB" | myDB | myDB |
|"mongodb://user:pwd#hostname?authSource=admin" | admin | test |
|"mongodb://user:pwd#hostname" | admin | test |
+-------------------------------------------------------------------------------------+
I guess you created the user in admin database but as you don't specify authenticationDatabase while connecting, Mongo defaults it to mydatabase where it fails, because user does not exist in database mydatabase.
I am going to create a simple lolminer electron apps for my school project.
So I download lolminer and setup the batch file
lolMiner.exe --algo ETHASH --pool ethash.unmineable.com:3333 --user DOGE:DK32SaiLzRn9npSwxzCoCY8BLbHMAqiUVV.Desktop --ethstratum ETHPROXY
pause
then I try to run the batch with this code
require('child_process').exec('cmd /c mining.bat', function(err, stdout, stderr){
// …you callback code may run here…
if (err) {
console.error(err);
return;
}
console.log(stdout);
});
but it return nothing.
and I try to insert arguments but no luck.
const execFile = require('child_process').execFile;
const child = execFile('lolMiner.exe', ['--algo','ETHASH','--pool','ethash.unmineable.com:3333','--user','DOGE:DK32SaiLzRn9npSwxzCoCY8BLbHMAqiUVV.Desktop'], (err, stdout, stderr) => {
if (err) {
throw err;
}
console.log(stdout);
});
But this does return something
const execFile = require('child_process').execFile;
const child = execFile('lolMiner.exe', ['--algo','ETHASH'], (err, stdout, stderr) => {
if (err) {
throw err;
}
console.log(stdout);
});

I still can't make it run.
My idea is to let user input their wallet address, choose their algo and run the lolminer.
is this idea work or I can't make it done with node.js

TO use react-hook-forms, theres some fix to work:
The inputs fields calls the register function. This function has 2 params:
register(field_name <- string, options <- object);
In your case, you need to call it like that:
<input type='email' name='email' id='email' ref={register("email", {required:true}) } />
<input type='password' name='password' id='password'
ref={register("password", {required:true, minLength:6, maxLength: 10} )} />
You're calling the error object the wrong way. Thats how you should call it:
const { register, handleSubmit, formState: { errors }, reset } = useForm();
The last error I found after the fix is about the way you call register function.
You are setting the register at the ref property. According to the docs, you should just set the register in the component, and this will return all the props:
<input type='email' id='email' {...register("email", {required:true}) } />
Here at the Sources, you can read and deep in "why am I doing this?" =):
register():
https://react-hook-form.com/api/useform/register
errors:
https://react-hook-form.com/api/useformstate/errormessage
I'll add here some tips to help you found the solution to new errors:
Make a path to discover where to focus: When you have an error, you need to found exactly what's causing it. In your case, the console was accusing a file that isn't even in your main folders (that was a dependency). In that case, remove code, try to delete some code, and see if the project works. If works, you now is somewhere there, and do again filtering the removed code.
Go to the official docs/demos and compare your code: I've never used react-hook-forms, But a look at the docs helps me to find the errors.
I have two projects in my application:
App/AppServer
libraries/domain
Below is the folder structure:
+---apps
| \---AppServer
| +---config
| +---node_modules
| +---src
| | +---auth
| | | \---dto
| | +---config
| | +---masterDataHttp
| | \---tasks
| | +---dto
| | \---pipes
| \---test
+---libraries
| \---domain
| +---node_modules
| \---src
| \---masterData
\---node_modules
I have some entities defined under libraries\domain\src\masterData and a few entities under apps\AppServer\src\tasks.
My ormconfig is defined under apps\AppServer\src\config. It imports the entities using
__dirname + '/../**/*.entity.{js,ts}'
Using above we can import entities under apps\AppServer\src. But I am trying to figure out what best approach to import entities defined under libraries\domain\src.
One option is import entities directly using
import { Entity1, Entity2 } from '#myproj/domain'
What is the recommended practice/approach to address this? TIA
Importing the entities directly
entities: [__dirname + '/../**/*.entity.{js,ts}', Entity1, Entity2]
Or you could wrap all of the entities of the library in a variable:
// libraries/domain
export const entities = [Entity1, Entity2];
// importing the entities
import { entities } from '#myproj/domain' ;
...
entities: [__dirname + '/../**/*.entity.{js,ts}', ...entities]
Importing the entities with path string as you already do
entities: [
__dirname + '/../**/*.entity.{js,ts}',
'src/libraries/domain/**/*.entity.{js,ts}'
]
This will just work.
