pagination

Overview ¶

The pagination package provides utilities to setup a paginator within the context of a http request.

Usage ¶

In your beego.Controller:

package controllers

import "github.com/astaxie/beego/utils/pagination"

type PostsController struct {
  beego.Controller
}

func (this *PostsController) ListAllPosts() {
    // sets this.Data["paginator"] with the current offset (from the url query param)
    postsPerPage := 20
    paginator := pagination.SetPaginator(this.Ctx, postsPerPage, CountPosts())

    // fetch the next 20 posts
    this.Data["posts"] = ListPostsByOffsetAndLimit(paginator.Offset(), postsPerPage)
}

In your view templates:

{{if .paginator.HasPages}}
<ul class="pagination pagination">
    {{if .paginator.HasPrev}}
        <li><a href="{{.paginator.PageLinkFirst}}">{{ i18n .Lang "paginator.first_page"}}</a></li>
        <li><a href="{{.paginator.PageLinkPrev}}">&laquo;</a></li>
    {{else}}
        <li class="disabled"><a>{{ i18n .Lang "paginator.first_page"}}</a></li>
        <li class="disabled"><a>&laquo;</a></li>
    {{end}}
    {{range $index, $page := .paginator.Pages}}
        <li{{if $.paginator.IsActive .}} class="active"{{end}}>
            <a href="{{$.paginator.PageLink $page}}">{{$page}}</a>
        </li>
    {{end}}
    {{if .paginator.HasNext}}
        <li><a href="{{.paginator.PageLinkNext}}">&raquo;</a></li>
        <li><a href="{{.paginator.PageLinkLast}}">{{ i18n .Lang "paginator.last_page"}}</a></li>
    {{else}}
        <li class="disabled"><a>&raquo;</a></li>
        <li class="disabled"><a>{{ i18n .Lang "paginator.last_page"}}</a></li>
    {{end}}
</ul>
{{end}}
