My goal is to move the contents of UsersArray into generateUserData() so that I can display it in a TableViewController.
[usernameList() and idList() get a response message from a URL request]
final class UsersData {
static func generateUsersData() -> Array<User>
{
return [
User(id: "111", username: "Bill#comcast.net"),
User(id: "222", username: "Oscar Peterson#yahoo.com"),
User(id: "333", username: "DaveBrubeck#gmail.com")
]
}
}
func makeUsers() {
usernameList() {
inputArray in
arrayOfUsernames = inputArray as! [String]
idList() {
inputArray in
arrayOfids = inputArray as! [String]
var counter = arrayOfids.count - 1
print(counter)
while counter > 0 {
usersArray.append(User(id: arrayOfids[counter], username: arrayOfUsernames[counter]))
counter -= 1
}
print("makeUsers() creates this array in idList() closure: \(usersArray)")
}
}
}
This is printed to the console:
makeUsers() creates this array in idList() closure: [Project1.User(id: Optional(""), username: Optional("")), Project1.User(id: Optional("62"), username: Optional("83068151#qq.com")), Project1.User(id: Optional("56"), username: Optional("830681511#qq.com")), Project1.User(id: Optional("55"), username: Optional("in#ultrices.edu")), Project1.User(id: Optional("54"), username: Optional("non.lacinia#pretiumet.com")), Project1.User(id: Optional("53"), username: Optional("pede#utodio.org")), Project1.User(id: Optional("52"), username: Optional("tincidunt#congueInscelerisque.co.uk")), Project1.User(id: Optional("51"), username: Optional("enim#liberoProin.ca")), Project1.User(id: Optional("50"), username: Optional("amet.massa#nectellus.net")), Project1.User(id: Optional("49"), username: Optional("auctor.Mauris#nibhenimgravida.edu")), Project1.User(id: Optional("48"), username: Optional("Curae.Phasellus.ornare#parturientmontes.ca")), Project1.User(id: Optional("47"), username: Optional("pede.blandit#Pellentesquehabitant.net")), Project1.User(id: Optional("46"), username: Optional("Maecenas#natoquepenatibus.ca")), Project1.User(id: Optional("45"), username: Optional("non.lobortis#nunc.edu")), Project1.User(id: Optional("44"), username: Optional("Sed#interdum.net")), Project1.User(id: Optional("43"), username: Optional("vehicula.risus#urnasuscipit.com")), Project1.User(id: Optional("42"), username: Optional("libero#dui.co.uk")), Project1.User(id: Optional("41"), username: Optional("fames#Nullatemporaugue.edu")), Project1.User(id: Optional("40"), username: Optional("eget.ipsum.Suspendisse#facilisis.ca")), Project1.User(id: Optional("39"), username: Optional("felis.Nulla.tempor#adipiscinglacusUt.net")), Project1.User(id: Optional("38"), username: Optional("erat.neque.non#in.co.uk")), Project1.User(id: Optional("37"), username: Optional("tincidunt.dui.augue#sedturpis.ca")), Project1.User(id: Optional("36"), username: Optional("ultrices.iaculis#adipiscingelitAliquam.org")), Project1.User(id: Optional("35"), username: Optional("montes.nascetur#etmagnisdis.edu")), Project1.User(id: Optional("34"), username: Optional("Phasellus.nulla.Integer#nunc.edu")), Project1.User(id: Optional("33"), username: Optional("Donec.tincidunt#Quisque.edu")), Project1.User(id: Optional("32"), username: Optional("In#afelisullamcorper.edu")), Project1.User(id: Optional("31"), username: Optional("neque.Nullam.ut#eleifend.edu")), Project1.User(id: Optional("30"), username: Optional("mus.Aenean#tellussemmollis.org")), Project1.User(id: Optional("29"), username: Optional("Donec.dignissim#Nunc.org")), Project1.User(id: Optional("28"), username: Optional("gravida.molestie#habitant.edu")), Project1.User(id: Optional("27"), username: Optional("egestas#sedtortor.org")), Project1.User(id: Optional("26"), username: Optional("non.enim#semut.com")), Project1.User(id: Optional("25"), username: Optional("nec#tinciduntvehicula.ca")), Project1.User(id: Optional("24"), username: Optional("nec.ante.blandit#consequatdolor.ca")), Project1.User(id: Optional("23"), username: Optional("sit.amet.metus#Pellentesquetincidunttempus.org")), Project1.User(id: Optional("22"), username: Optional("convallis.dolor.Quisque#natoquepenatibuset.edu")), Project1.User(id: Optional("21"), username: Optional("lacus#molestietellus.com")), Project1.User(id: Optional("20"), username: Optional("dui#NullaaliquetProin.edu")), Project1.User(id: Optional("19"), username: Optional("ullamcorper.velit#necmalesuadaut.com")), Project1.User(id: Optional("18"), username: Optional("risus#nibh.ca")), Project1.User(id: Optional("17"), username: Optional("scelerisque.lorem#dolorsit.net")), Project1.User(id: Optional("16"), username: Optional("Nulla.interdum#parturientmontesnascetur.net")), Project1.User(id: Optional("15"), username: Optional("ipsum.non#erat.co.uk")), Project1.User(id: Optional("14"), username: Optional("commodo.tincidunt#molestiesodales.com")), Project1.User(id: Optional("13"), username: Optional("cursus.Integer.mollis#eleifendnon.net")), Project1.User(id: Optional("12"), username: Optional("eleifend.vitae#etmagnisdis.co.uk")), Project1.User(id: Optional("11"), username: Optional("et.lacinia.vitae#inconsequatenim.net")), Project1.User(id: Optional("10"), username: Optional("dictum.magna#auctorullamcorpernisl.com")), Project1.User(id: Optional("9"), username: Optional("tempus.mauris.erat#ametfaucibus.net")), Project1.User(id: Optional("8"), username: Optional("iaculis.odio.Nam#ligulatortor.org")), Project1.User(id: Optional("7"), username: Optional("enim.condimentum#elementum.org")), Project1.User(id: Optional("6"), username: Optional("parturient#Aeneanmassa.com")), Project1.User(id: Optional("5"), username: Optional("")), Project1.User(id: Optional("4"), username: Optional("testguy#aol.com"))]

I am working on a database migration project and it requires me to use sequelize. I initialized sequelize's CLI (using npx sequelize-cli init) that added the config.json file:
config, contains config file, which tells CLI how to connect with database
The config.json file has this object:
"production": {
"username": "root",
"password": null,
"database": "database_production",
"host": "127.0.0.1",
"dialect": "mysql"
}
But I don't want to save my password in a config.json file. I want to use an environmental variable instead. What can I do?
Rename the config.json to config.js, install dotenv and use the below code
require('dotenv').config();
module.exports = {
development: {
username: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
host: process.env.DB_HOST,
dialect: process.env.DB_DRIVER
},
test: {
username: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
host: process.env.DB_HOST,
dialect: process.env.DB_DRIVER
},
production: {
username: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
host: process.env.DB_HOST,
dialect: process.env.DB_DRIVER
}
};
First you have to create a .sequelizerc file in root. Then add the following code there.
var path = require('path')
module.exports = {
'config': path.resolve('config', 'config.js'),
}
Note: Change the path as per your project.
Then you can rename the config.json file to config.js and add the below code there. (As in Tunde's answer.)
require('dotenv').config();
module.exports = {
development: {
username: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
host: process.env.DB_HOST,
dialect: process.env.DB_DRIVER
},
test: {
username: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
host: process.env.DB_HOST,
dialect: process.env.DB_DRIVER
},
production: {
username: process.env.DB_USER,
password: process.env.DB_PASSWORD,
database: process.env.DB_NAME,
host: process.env.DB_HOST,
dialect: process.env.DB_DRIVER
}
};
I have User and UserEmails models.
User columns: id, first_name, last_name
UserEmails: id, user_id, email, primary
I need a function like this(https://imgur.com/a/762iK9r)
The essence is this: duplicate users are identified by or emails.
Example:
User 1:
{ id: 1, first_name: 'Test', last_name: 'User1' }
UserEmails for User 1:
{ email: 'same_email3#test.com', primary: true, user_id: 1 }
User 2:
{ id: 2, first_name: 'Test', last_name: 'User2' }
UserEmails for User 2:
{ { email: 'same_email#test.com', primary: true, user_id: 2 }, { email: 'same_email1#test.com', primary: false, user_id: 2 }, { email: 'same_email3#test.com', primary: false, user_id: 2 } }
User 3:
{ id: 3, first_name: 'Test', last_name: 'User3' }
UserEmails for User 3:
{ { email: 'same_email#test.com', primary: true, user_id: 3 }, { email: 'same_email3#test.com', primary: false, user_id: 3 }, { email: 'same_email4#test.com', primary: false, user_id: 3 } }
I need a query which will find that duplicates and return an ids array like this:
[[1, 2, 3], [...]]
I have a query but it incorrectly displays an array of ids:
ids = User.left_outer_joins(:user_emails)
.select('array_agg(users.id) AS ids')
.where('user_emails.email IS NOT NULL')
.group("user_emails.email")
.having('COUNT(1) > 1')
.map(&:ids)
I get this array, but the array [2, 3] is already in the array [1,2,3].
[[1, 2, 3], [2, 3]]
How I can group or sort the array ids that would not be duplicated in case of display of users which are duplicates by email?
You can try self join to find duplication
select distinct(u1.user_id) from public.UserEmails u1, public.UserEmails u2
where u1.email = u2.email
Is it possible to use connection class as provide like here?
import { Connection, createConnection } from 'typeorm';
export const databaseProviders = [{
provide: Connection,
useFactory: async () => await createConnection({
type: 'postgres',
host: 'localhost',
port: 5432,
username: 'postgres',
password: 'postgres',
database: 'testo',
entities: [
__dirname + '/../**/*.entity{.ts,.js}',
],
logging: true,
synchronize: true,
}),
}];
To make imports work like:
constructor(
private connection: Connection,
) {
this.repository = connection.getRepository(Project);
}
In that case nestjs can't find dependency. I guess the problem is in typeorm, it is compiled to plain es5 function. But maybe there a solution for this?
repository to reproduce
UPDATE:
I found acceptable solution nestjs typeorm module, but don't understand why my Connection class is not worked, but it works well with strings. Hope #kamil-myśliwiec will help to understand.
modules: [
TypeOrmModule.forRoot(
[
Build,
Project,
],
{
type: 'postgres',
host: 'localhost',
port: 5432,
username: 'postgres',
password: 'postgres',
database: 'testo',
entities: [
Build,
],
logging: true,
synchronize: true,
}),
],
// And the n inject like this by entity name
#InjectRepository(Build) private repository: Repository<Build>,
I'm creating an API with Rails and Neo4j and i have a query looks like this on my model
Neo4j::Session.query.match('(User)').where("lower(User.first_name) =~ '.*#{params[:name].downcase}.*'").return('User')
this query return json looks like
[
{
User: {
user: {
username: null,
password: null,
first_name: "ayman",
last_name: "eldeeb",
email: "ayman#gmail.com",
phone: "44555",
avatar: "url",
birthdate: "1990-12-26"
}
}
}
]
Now, how to convert this json in Ruby on Rails to this below?
{
users: [
{
id: 0,
username: null,
first_name: "adham",
last_name: "eldeeb",
phone: "010220234",
email: null,
avatar: "url",
birthdate: null
}
]
}
Not sure, but this can probably work..
require 'json' #this has to be in the top
.....
#data = JSON.parse(Neo4j::Session.query.match('(User)').where("lower(User.first_name) =~ '.*#{params[:name].downcase}.*'").return('User'))
Now #data will be a ruby variable parsed from the JSON output..
Now to get your desired output, maybe the following snippet can help
#desired_data = []
#data.each do |d|
#desired_data << d[:User][:user] # this could be d["User"]["user"] if this dosen't work
end
I have recently attempted to create an application that allows me to compare 3 separate databases for their values. The databases are 3 Oracle instances which house (essentially) the same database, but in a DEV/TEST/PROD setting.
What I want to do is create one Domain class in GRAILS 3. I then want to be able to fetch the records which that domain class maps to, but do it for all 3 environments.
From reading the Grails 3 docs, it looks like this should be possible by defining 3 datasources in application.yml (in my example here I define 4):
dataSources:
dataSource:
pooled: true
jmxExport: true
logSql: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#someserver:1521:DEV1
dataSource1:
pooled: true
jmxExport: true
logSql: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#someserver:1521:DEV1
dataSource2:
pooled: true
jmxExport: true
logSql: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#someserver:1521:TEST1
dataSource3:
pooled: true
jmxExport: true
logSql: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#someserver:1521:PROD1
and then within the domain class' mapping specifying datasources in the mapping:
package plsutils
class DmjTypes {
String code
String description
Date insertDate
String insertUser
Date modifyDate
String modifyUser
String dbEnv
static mapping = {
datasources(['dataSource1', 'dataSource2', 'dataSource3'])
version false
table name: "CDE_DMJ_TYPES", schema: "MYSCHEMA"
id generator: 'sequence' ,params:[sequence: 'DMJTY_SEQ']
columns {
id column: "DMJTY_ID"
code column: "DMJTY_CDE"
description column: "DMJTY_DESCR"
insertDate column: "INSERT_DTT"
insertUser column: "INSERT_USER"
modifyDate column: "MODIFY_DTT"
modifyUser column: "MODIFY_USER"
dbEnv formula:'( select inst.instance_name || \'-\' || inst.host_name from v$instance inst ) '
}
}
}
and then, within my controller, I should be able to do something like this:
params.max = Math.min(max ?: 10, 100)
dmjTypesListDev = DmjTypes.dataSource1.list(params)
dmjTypesListTest = DmjTypes.dataSource2.list(params)
dmjTypesListProd = DmjTypes.dataSource3.list(params)
I am getting an error upon the first call:
URI /dmjTypes/index
Class groovy.lang.MissingPropertyException
Message null
Caused by No such property: dataSource1 for class: plsutils.DmjTypes
I'm using ojdbc7.jar, connection to Oracle 11g and I'm using Grails 3.0.9.
I can't help but think I'm doing something subtly stupid somewhere. Can anyone please help me with this?
Cheers,
Allen
Basing on official documantation try dataSources keyword:
dataSources:
dataSource:
pooled: true
jmxExport: true
driverClassName: org.h2.Driver
username: sa
password:
lookup:
dialect: org.hibernate.dialect.MySQLInnoDBDialect
driverClassName: com.mysql.jdbc.Driver

Once I corrected the version of grails referred to in the gradle.properties and performed a complete clean and rebuild, I was able to get it working. I believe all my issues were because of a version mismatch of the grails I was using to build it.
So, this is the appropriate datasource entry:
dataSources:
dataSource:
pooled: true
jmxExport: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#somelocalserver:1521:LOCAL
one:
pooled: true
jmxExport: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#somedevserver:1521:DEV1
two:
pooled: true
jmxExport: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#sometestserver:1521:TEST1
three:
pooled: true
jmxExport: true
driverClassName: oracle.jdbc.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
url: jdbc:oracle:thin:#someproductionserver:1523:PROD1
This is the working domain class:
class DmjTypes {
String code
String description
Date insertDate
String insertUser
Date modifyDate
String modifyUser
String dbEnv
static mapping = {
datasources(['one', 'two', 'three'])
version false
table name: "CDE_DMJ_TYPES", schema: "MYSCHEMA"
id generator: 'sequence' ,params:[sequence: 'DMJTY_SEQ']
columns {
id column: "DMJTY_ID"
code column: "DMJTY_CDE"
description column: "DMJTY_DESCR"
insertDate column: "INSERT_DTT"
insertUser column: "INSERT_USER"
modifyDate column: "MODIFY_DTT"
modifyUser column: "MODIFY_USER"
dbEnv formula:'( select inst.instance_name || \'-\' || inst.host_name from v$instance inst ) '
}
}
}
Try this:
dataSources:
dataSource:
pooled: true
jmxExport: true
logSql: true
driverClassName: oracle.jdbc.driver.OracleDriver
username: MYUSER
password: Password1
dbCreate: validate
autoReconnect: true
