Golang gin relaxation api submit and get – Getting Assist

With golang gin relaxation api I create title, physique, date, titles and contents fields, ship to postman and save database. The submit operation is working efficiently, however once I obtain the information, I get an error like this: “error”: “didn’t import jobs” get doesn’t work however submit works code components are as follows

predominant.go:

sort Job struct {
    ID       int       `db:"id" json:"id"`
    Title    string    `db:"title" json:"title"`
    Physique     string    `db:"physique" json:"physique"`
    Date     time.Time `db:"date" json:"date"`
    Titles   [4]string `db:"titles" json:"titles"`
    Contents [4]string `db:"contents" json:"contents"`
}

func predominant() {
r.POST("/job", func(c *gin.Context) {
    var job Job
    if err := c.ShouldBindJSON(&job); err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()})
        return
    }

    // insert job into database
    question := "INSERT INTO desk (title, physique,  titles, contents ,date) VALUES ($1, $2, $3,  $4, $5) RETURNING id"
    var id int
    err := db.QueryRow(question, job.Title, job.Physique, pq.Array(job.Titles), pq.Array(job.Contents), time.Now()).Scan(&id)
    if err != nil {
        c.JSON(http.StatusInternalServerError, gin.H{"error": "didn't create job"})
        return
    }

    job.ID = id

    c.JSON(http.StatusOK, job)
})

r.GET("/jobs", func(c *gin.Context) {
    // retrieve all jobs from database
    rows, err := db.Question("SELECT * FROM desk")
    if err != nil {
        c.JSON(http.StatusInternalServerError, gin.H{"error": "didn't retrieve jobs"})
        return
    }
    defer rows.Shut()

    // iterate over rows and retailer in slice of Jobs
    jobs := []Job{}
    for rows.Subsequent() {
        var job Job
        err := rows.Scan(&job.ID, &job.Title, &job.Physique, &job.Date, &job.Titles, &job.Contents)
        if err != nil {
            c.JSON(http.StatusInternalServerError, gin.H{"error": "didn't retrieve jobs"})
            return
        }
        jobs = append(jobs, job)
    }

    c.JSON(http.StatusOK, jobs)
})`

It’s best to log the err someplace so you already know the underlying trigger.

This error is available in error part : ” didn’t retrieve jobs”

jobs := []Job{}
for rows.Subsequent() {
var job Job
err := rows.Scan(&job.ID, &job.Title, &job.Physique, &job.Date, &job.Titles, &job.Contents)
if err != nil {
c.JSON(http.StatusInternalServerError, gin.H{“error”: “didn’t retrieve jobs”})
return
}
jobs = append(jobs, job)

// Debugging statements
fmt.Printf("Retrieved job with ID %dn", job.ID)
fmt.Printf("Title: %sn", job.Title)
fmt.Printf("Physique: %sn", job.Physique)
fmt.Printf("Date: %sn", job.Date)
fmt.Printf("Titles: %vn", job.Titles)
fmt.Printf("Contents: %vn", job.Contents)

}

What I imply is your choose assertion returns rows and an err. That err doubtless has data in it explaining why your SQL assertion failed. If you verify if err != nil, it’s best to log err itself so you already know what the issue is:

rows, err := db.Question("SELECT * FROM desk")
if err != nil {
    c.JSON(http.StatusInternalServerError, gin.H{"error": "didn't retrieve jobs"})
    // Returning a basic "didn't retrieve jobs" message right here
    // is ok on your API, however it's best to log `err` itself
    // someplace in right here:
    //
    // TODO: import "log"
    log.Print("error getting jobs: %v", err)
    return
}

it really works however the values ​​are empty

Are you able to make clear which values are empty?

Values ​​usually are not coming once I get it, clean web page however 200 freezes

Sorry, @Coding_Yaz, I’m having a tough time understanding:

The log.Print change I prompt wasn’t to repair a difficulty, it was simply to get extra details about the reason for the SQL assertion failing. Did you see an error and make a change to deal with it, or are you saying that after including a name to log.Print, now you’re not getting an error, however the web site is one way or the other hanging? Are you getting any output to your console if you run your Go program?

I’m undecided what you imply right here: Are you getting a clean web page and/or a 200 response, or is the web page “freezing?” I’d suppose “freezing” implies that you’re not getting a response in any respect; is that occuring? Or are you maybe working some client-side javascript that’s alleged to do one thing with the response but it surely’s freezing?

sorry i simply noticed this in debugging

2023/03/21 17:25:21 Error scanning job from database: sql: Scan error on column index 3, identify “titles”: unsupported Scan, storing driver.Worth sort string into sort *time.Time

That error appears to point that you simply’re scanning your titles column into your &job.Date discipline. I’d advocate as a substitute of writing choose * from ... that you choose the columns explicitly in order that including/eradicating/reordering columns sooner or later is much less more likely to produce errors like these.
