我是初学者流星。我根据每个类别创建了一个包含许多帖子(文章)的博客。这是我的收藏:
if (Category.find().count() === 0) {
[
{
name: 'IT',
sub_categories: [
{ name: 'Java' },
{ name: 'PHP' },
{ name: '.NET' },
{ name: 'Android/iOS' },
{ name: 'HTML/CSS' },
{ name: 'Javascript and Framworks' },
{ name: 'Ruby on Rails' },
],
},
{
name: 'ENGLISH',
sub_categories: [
{ name: 'Listening' },
{ name: 'Speaking' },
{ name: 'Writing' },
{ name: 'Reading' },
{ name: 'Topic' },
],
},
{
name: 'SoftSkill',
sub_categories: [
{ name: 'CV and CL' },
{ name: 'Presentation' },
{ name: 'Teamwork' },
],
},
{
name: 'ENTERTAINMENT',
sub_categories: [
{ name: 'Sports' },
{ name: 'Games' },
{ name: 'Music & Videos' },
{ name: 'Fashion' },
{ name: 'Talk show' },
],
},
].forEach(doc => {
Category.insert(doc);
});
}
按照每个类别保存所有帖子后,现在我想通过选择选项
显示它详情:
当我点击“IT”按钮 - > app显示所有sub_categories。然后我选择一个选项(例如“Java”),它将显示所有帖子都有sub_categories
=“Java”。你能帮帮我吗?
