Question

有没有办法使用gmaps4rails gem查看标记，具体取决于当前用户登录？我不确定它是否有可能已经解决，但我尝试组合使用康康宝石，但它只会导致所有标记消失。不幸的是，我不知道如何继续。所以我想要实现的是根据当前登录的用户使标记可见。我很感激任何帮助！

relations_controller的当前代码：

$model = LoanInformation::select(
       'loan_information.id', 'loan_information.tenor',
       'basic_information.first_name', 'basic_information.last_name'
)->leftjoin(
       'basic_information', 'loan_information.user_id', '=', 
       'basic_information.user_id'
)->where('loan_information.status', 'funding')
->orderBy('loan_information.created_at', 'ASC')
->paginate(9);

foreach($model as $key => $value) {
   $tx_funding = TxFunding::whereLoanId($value->id)->get();
   $name = substr($value->first_name, 0, 1).substr($value->last_name, 0, 2);

   $model[$key]['name'] = strtoupper($name);
   $model[$key]['grade'] = 'A+';
   $model[$key]['fundraiser'] = $tx_funding->count();
   $model[$key]['progress'] = 50;
   $model[$key] = array_except($value, ['first_name', 'last_name']);
}

return response()->json($model);

关系索引视图中的代码：

    def index

    @relations = Relation.all

@hash1 = Gmaps4rails.build_markers(@relations) do |relation, marker|
    # something like "if current_user == relation.user_id" ?
    marker.lat relation.childlat
    marker.lng relation.childlng

    marker.picture({
              :url    => ActionController::Base.helpers.image_path("childgross.png"),
              :width  => "45",
              :height => "45"
             })
 end

@hash2 = Gmaps4rails.build_markers(@relations) do |relation, marker|
    marker.lat relation.kigalat
    marker.lng relation.kigalng
    marker.picture({
            :url    => ActionController::Base.helpers.image_path("persongross.png"),
            :width  => "45",
            :height => "45"
            })
 end
end

向@Pablo致敬它刚刚来找我......我只需要用@relations = Relation.all替换@relations = Relation.where(user_id: current_user.id)

Gmaps4rails标记取决于当前用户
