Respond_to混乱
我有一个编辑/更新表单，我通过form_for设置：
在有效数据的情况下，我希望相应的更新操作保存更改，并将用户重定向到他来自的位置。 在这种情况下不需要JS。 如果数据无效，我希望JS处理这种情况。 我把控制器设置成这样：
def update @user = current_user @vocab = @user.vocabs.find(params[:id]) if @vocab.update_attributes(vocab_params) flash[:notice] = "Vocab updated!" respond_to do |format| format.js { redirect_back_or(home_user_path(@user)) } end else flash[:error] = "Vocab invalid!" respond_to do |format| format.html { render 'edit' } format.js { render file: "vocabs/update.js" } end end end
我遇到的问题是，在有效数据的情况下，保存的URL（study_setup）正在被处理为JS，这可以防止端被加载。 我在哪里告诉Rails使用JS进行此重定向？
