Question

当我在Meteor应用程序上创建一个帐户时，我会在几次检查每个元素的有效性。然后我创建了用户。如果没有出现错误，我会显示成功div，而另一个则显示错误。

Accounts.createUser(options ,function(err){
      if(err){
        console.log("rorororororroro");
        if(err.message == "Email already exists. [403]"){
          Session.set('error', regAlert("This email adress already exists", tmpl));
        }else{
          Session.set('error', regAlert("Sorry, but an unidentified error occured. Please retry later. If the error persists, contact the support"));
        }
      }else if(Meteor.call('talknameIsAvailable', talkname)){
        Session.set('error', regAlert("A user with this talkname already exists", tmpl));
      }
    });
    if(!Session.get('error')){
      $('#register-success').show("slow");
      //console.log("[SUCCESS] Account created");
      //document.location.href="/";
    }else{
      $('#register-error').show("slow");
    }

问题是我总是显示成功div，因为最后if / else是在回调设置错误会话var之前计算的，当电子邮件已被使用时。

Meteor处理这种情况的最佳方式是什么？

谢谢你

当Session.get（＆＃34;错误＆＃34;）未定义时，（！Session.get（＆＃34; error＆＃34;））返回true。

尝试：

  def listado_publicaciones
    if params[:publicaciones]
      @Publicaciones = params[:publicaciones]
    else
      @Publicaciones = Proyecto.where("concurso_id","=",@concurso.id).as_json({:include => [:creador => {:only =>[:id],:include =>[:ficha =>{:only =>[:nombres,:apellidos], :methods => [:fullname],:include => [:publicacions => {:only =>[:id,:omitir,:anio,:titulo,:revista_nombre,:primer_autor,:autor_correspondiente,:coautor,:estado_id],:include => [:subtipo]}]}]}]})
    end
    respond_to do |format|
      format.html
      format.json { render :json => @Publicaciones}
      format.xlsx
    end
  end

我在.wait()函数的末尾添加了createUser：

Accounts.createUser(options ,function(err){
  if(err){
    console.log("rorororororroro");
    if(err.message == "Email already exists. [403]"){
      Session.set('error', regAlert("This email adress already exists", tmpl));
    }else{
      Session.set('error', regAlert("Sorry, but an unidentified error occured. Please retry later. If the error persists, contact the support"));
    }
  }else if(Meteor.call('talknameIsAvailable', talkname)){
    Session.set('error', regAlert("A user with this talkname already exists", tmpl));
  }
}).wait();
