spfx – Call external API in the SharePoint framework

Your SharePoint site needs to be loaded https and you call insecure http Request.

Therefore, the request is blocked in the SharePoint Workbench.

Instead, you can try calling GET call on one of your SharePoint lists as follows:

siteUrl / _api / web / lists / getbytitle (& # 39; ListName & # 39;) / items

Or try another dummy REST API https, to like:

https://jsonplaceholder.typicode.com/todos/1

Golang and Gin Framework: Best practices for connecting to Postgresql

I come from this question.

Project

A very simple project with Gin Framework with an endpoint to return a list of users based on their score.

structure

LiveOps tool
- users
---- model
------ user.go
---- Service
------ userService.go
---- Dao
------ directory.go (interface)
------ userDirectory.go (mock the database)
------ userPostgresDirectory.go
- main.go

main.go

r.GET ("/ competition / users", func (c * gin.Context) {
numUsers, err: = strconv.Atoi (c.DefaultQuery ("numusers", "6"))
minScore, err: = strconv.Atoi (c.DefaultQuery ("minscore", "0"))
maxScore, err: = strconv.Atoi (c.DefaultQuery ("maxscore", "2000"))
fmt.Printf ("numUsers:% d, minScore:% d, maxScore:% d  n", numUsers, minScore, maxScore)

if err == nil {
var userDirectoryService = userService.NewService (userDirectory.UserPostgrestDirectory {})
var res = userDirectoryService.GenerateUserListByScore (number of users, min., max.)
c.JSON (http.StatusOK, gin.H {"user": res})
} else {
c.JSON (http.StatusBadRequest, gin.H {"users": "no valid"})
}

})

userService.go

Package users

introduce (
dao "live-tool / user / dao"
models "liveops-tool / users / models"
)

Type UserService struct {
you dao.Directory
}

func NewService (dir dao.Directory) * UserService {
var service = & UserService {
you: you,
}
Return Service
}

// GenerateUserListByScore returns a list of users for a tournament
func (u UserService) GenerateUserListByScore (numUsers, minScore, maxScore int) []models.User {
return u.dir.SearchUsers (numUsers, minScore, maxScore)
}

userPostgresDirectory.go

Package users

introduce (
"database / sql"
"Fmt"
models "liveops-tool / users / models"
"Strings"

_ "github.com/lib/pq"
)

const (
host = "localhost"
port = 5432
user = "postgres"
password = "XXXX"
dbname = "XXXX"
)

Type UserPostgrestDirectory struct {
}

func (u UserPostgrestDirectory) getConnection () * sql.DB {
psqlInfo: = fmt.Sprintf ("host =% s port =% d user =% s" + "password =% s database name =% s SSL mode = disable", host, port, user, password, database name)
db, err: = sql.Open ("postgres", psqlInfo)
checkErr (err)

back db
}


func (u UserPostgrestDirectory) SearchUsers (number of users, minScore, maxScore int) []models.User {
db: = u.getConnection ()
Move db.Close ()
err: = db.Ping ()
checkErr (err)

fmt.Println ("Successfully connected!")

Rows, err: = db.Query ("SELECT * FROM user WHERE total_score> = $ 1 AND total_score <= $ 2 LIMIT $ 3", minScore, maxScore, numUsers)
if err! = nil {
panic
}

var users = []models.user {}
for rows.Next () {
var id int
var name string
var country string
var total_score int
err = rows.Scan (& name, & id, & country, & total_score)
checkErr (err)
fmt.Println ("id | name | country | total_score")
fmt.Printf ("% 3v |% 8v |% 6v |% 6v  n", ID, name, country, total score)
user: = models.User {
I did,
Name: strings.TrimSpace (name),
Country: strings.TrimSpace (Country),
TotalScore: total_score,
}

users = append (user, user)
}
Return user
}

func checkErr (error) {
if err! = nil {
panic
}
}

ask

  • Is it possible to get the connection directly or apply a singleton pattern to avoid creating a connection each time the SearchUsers method is called? I even tried to pass the connection through the UserPostgrestDirectory constructor from main.go, but I always get the error message "The database is closed".

All other feedback on the code is welcome.

wolfram data framework – Implicitly defined EntityClass does not work

When studying, how can I use that Wolfram Data Framework In a database on my private computer I found a strange problem. I created one EntityStore for my database and register that. The entities with their properties are available. For example:

persoon = entity["personen", 1]["voornaam"]



(* Lucas *)

Therefore, I expected the following construction to yield an entity class containing at least one entity. But it remains unweighted:

entityClass["personen", "voornaam"->"Lucas"]
(* EntityClass[personen,voornaam->Lucas] *)

My first thought, of course, was that it had to do with my private database. However, the following example from the documentation shows the same problem:

entityClass["Aircraft", {"CruiseSpeed" -> Quantity[Interval[{550, 600}], "Miles" / "Hours"].
"Height" -> quantity[Interval[{75, 200}], "Feet"].
"Span" -> number[Interval[{75, 80}], "Meter"]}](* EntityClass[Aircraft,{CruiseSpeed->(550to600)mi/h,Height->(75to200)ft,Wingspan->(75to80)m}] *)

I'm using Mathematica 12.0.0 for Microsoft Windows (64-bit) (April 6, 2019).

It looks like the construction of an implicitly defined entity class with the function entityClass does not work on my computer anyway. Is this due to an installation error on my system or is it a more general problem?

magento2 – (Magento Framework Config Dom ValidationException): element & # 39;; referenceBlock & # 39 ;, attribute & # 39; class & # 39 ;: the attribute & # 39; class & # 39; is not allowed

I have this problem and can not determine where the problem lies:

1 Exception (s): Exception # 0 (Magento  Framework  Config  Dom  ValidationException): Element # 39; referenceBlock #, Attribute # 39 ;: The attribute # 39; class & # 39; 39; is not permitted. Line: 1124

This issue occurs as a connected customer when I try to access the invoice for a trial order.

The following I have tried to solve the problem by following many topics in this forum:

  • setup: di: compile
  • Delete the contents of / pub / static / frontend
  • Provide static content

Nothing works.

Note that I searched for a reference block with a class attribute in my XML code, but did not find anything. Maybe I'm not looking in the right place?

The directories were searched for the error:
– / app / code
– / app / design

Can someone explain to me how to find this error more accurately? Or are you helping me to solve it?

mysql – "A non-numeric value found in DBColumn.php on line 68" in the Phreeze framework

Good evening everyone. I have this error when I ask for the software foundation after modeling, connecting and successfully populating MySQL.

if ($ this-> IsEnum ())
{
// enum size has the format & # 39; val1 & # 39 ;, val2 & # 39 ;, ...
$ this-> Size = explode ("& # 39;, & # 39;", substr ($ sizesign[0]1, -1));
$ this-> MaxSize = 0;
}
otherwise
{
$ this-> Size = $ sizesign[0];
// size can be stored for decimals as "n, n", so we need to convert that to an int
$ tmp = explode (",", $ this-> size);
$ this-> maxSize = count ($ tmp)> 1? ($ tmp[0] + tmp[1]): $ this-> size;
}

Here is a database entity in which you use Set (several others use Enum tbm):

CREATE TABLE IF NOT EXISTmydb,Teacher(
teacher_idINT NOT NULL AUTO_INCREMENT,
teacher nameVARCHAR (45) NOT NULL,
teacher_days_disponse_weekSET (# SECOND,, # TIME #, QU QUARTA,, FIF FIFTH #, S SIXTH #) NOT NULL,
professor_carga_horaria_semanalDOUBLE NOT ZERO,
teacher_turnosSET (& # 39; MATUTINO & # 39; VESPERTINO & # 39; NOTURNO & # 39;) NOT NULL,
PRIMARY KEY (
teacher_id))
ENGINE = InnoDB;

Does anyone know if it has support for EnumSet?

    Has anyone developed an ecommerce store in Core PHP (without MVC, Framework, CMS) etc. and used it for over a year?


  2. Sunshop is written with very little framework and is very easy to modify, but it is a paid solution. I have used it for years while I was developing web, and we still have a lot of customers who use it today and are very happy with it.

PowerApps and Flow versus SharePoint Framework

I tried to do some research online, but unfortunately I could only find articles about how great PowerApps and Flow are. I'm curious in the world of no-code / low-code solutions, where is the SharePoint Framework? When are PowerApps appropriate and when is SharePoint Framework appropriate for use? Is it still worth getting familiar with SharePoint Framework if you have a developer and coding background?
