Runtime error by using of function db.Insert

[giesan]

Hello everyone,

I am currently using version v2.0.0-alpha.3 and get the following error message when using the db.Insert function

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x7c3e2e]

goroutine 1 [running]:

exit status 2

Here is my code I tried with.

package main

import (
    c "github.com/ostafen/clover/v2"
    d "github.com/ostafen/clover/v2/document"
)

func main() {

    db, _ := c.Open(".")
    defer db.Close()

    db.CreateCollection("todos")

    // Create todos
    todo1 := d.NewDocument()
    todo1.Set("title", "delectus aut autem")
    todo1.Set("completed", false)
    todo1.Set("userId", 1)

    todo2 := d.NewDocument()
    todo2.Set("title", "quis ut nam facilis et officia qui")
    todo2.Set("completed", false)
    todo2.Set("userId", 2)

    var docs = make([]*d.Document, 2)
    docs = append(docs, todo1)
    docs = append(docs, todo2)

    db.Insert("todos", docs...)
}

Am I doing something wrong? Best regards andy

This snippet results in a slice with 4 documents, with the first 2 being nil. Try replacing:

var docs = make([]*d.Document, 2)

with:

var docs = make([]*d.Document, 0, 2)

Hello Stefano, thank you for your reply. I have now also found the solution. Sorry, that was my mistake. I close this issue. Many thanks and best regards andy
