Navigating the loop in Vue using JavaScript

I'm facing an issue where I need to send data at once, but whenever I try sending it in a loop, I end up getting 500 duplicate id status errors. I have a hunch that if I click on something in JavaScript, the data might be sent all at once.

assignment: function (event) {

            for (var i = 0; i < this.perPage; i++){
            this.$http.post('mass_assigment', {
                id_target: 5,
                id_cms_users: 4,
                updated_by: 5,
            })
                .then(function (response) {
                    console.log(response);
                })
                .catch(function (error) {
                    console.log(error);
                });
            }
        alert('success')
        if (event){
            alert(event.target.tagName)
        }
    }

Answer №1

The issue does not stem from the code itself or the data being transmitted. Rather, it arises from the backend's attempt to store the data using the same identifier, leading to a SQL rejection due to a constraint preventing duplicate data entry.

It is advisable to refrain from manually assigning primary keys, as it is better to let the system handle this automatically to avoid such conflicts.

If you are attempting to update an existing record or create a new one if no match is found, consider utilizing Laravel's FirstOrCreate method.
