对数据库的AJAX请求

Question

There are many checkbox pages in my Rails application.

When clicking on one checkbox, its id should immediately be written to database (I use postgresql)

Сheckbox id should be written to the table as an array.

How to implement this with ajax?

An example of my checkbox:

<input name="skill_list[127]" type="hidden" value="0">
<input class="m-enabled" id="skill_list_127" name="skill_list[127]" type="checkbox" value="1">
<label for="skill_list_127">Zoomerang</label>

Answer 1

UserSkillList controller:

def create
  skill_id = params[:skill_id].gsub(/\D/, '').to_i if params[:skill_id].present?

  @skill_record = UserSkillList.where(user_id: current_user.id).first

  @skill_record.skill_id += [skill_id]
  @skill_record.save
end

app.js:

$('input[type=checkbox]').click(function(){
    if ($(this).is(':checked')) {
        checkbox_id = $(this).attr('id');
        $.ajax({
            type: "POST",
            url: "/user_skill_list",
            data: {skill_id: checkbox_id}
        });
    };
});
