Golang GetOneByQuery Examples

Example #1

File: utils.go Project: carvenli/SCBlog

// 获取Tag列表
func GetTagSlug(caption string) string {
	var tag models.SC_Tag

	models.GetOneByQuery(models.DbTag, bson.M{"caption": caption}, &tag)

	return tag.Slug
}

Example #2

File: index.go Project: carvenli/SCBlog

// 标签页面
func (this *IndexController) TagList() {
	tag := this.Ctx.Input.Param(":tag")
	if tag == "" {
		this.Abort("404")
	}

	// 定义一个Tag
	var sctag models.SC_Tag

	// 获取标签信息
	models.GetOneByQuery(models.DbTag, bson.M{"slug": tag}, &sctag)

	if sctag.Id.Hex() == "" {
		this.Data["NotSearch"] = true
		this.TplNames = "home/index.html"
		return
	}

	tag = sctag.Caption

	this.Data["SiteName"] = tag
	this.Data["SubTitle"] = models.Option.SiteName
	this.Data["Keywords"] = models.Option.Keywords
	this.Data["Description"] = models.Option.Description

	// 定义一个Post列表
	var scposts []models.SC_Post

	// 获取文章数量
	count := models.Count(models.DbPost, bson.M{"type": "post", "tags": tag})

	// 获取分页数据
	page := pagination.NewPaginator(this.Ctx.Request, 10, count)
	// 设置分页数据
	this.Data["paginator"] = page

	// 获取文章列表
	models.GetDataByQuery(models.DbPost, page.Offset(), 10, "-created", bson.M{"type": "post", "tags": tag}, &scposts)
	// 设置文章列表
	this.Data["Lists"] = scposts
