horizon源码结构

/usr/share/pyshared/horizon/horizon   其他openstack也在这里例如, nova   novaclient   glance   keystone  keystoneclient..

 

 

/usr/lib/python2.7/dist-packages/horizon   其他openstack组件也在这里 ...进该目录后，用ll命令查看。该目录的文件有对应的指向  其实就是指向上面的那个目录里的文件

不同版本文件目录结构不大一样，但是大体能找到在什么地方 。本文以Essex版本介绍

/usr/share/pyshared/horizon/templates/horizon/_nav_list.html  左侧菜单的标签标题

/usr/share/pyshared/horizon/templates/horizon/_subnav_list.html  左侧菜单显示

/usr/share/pyshared/horizon/templatetags/horizon.py  控制左侧菜单显示

该文件最后一行：

{% horizon_dashboard_nav %}

 

horizon_dashboard_nav 在文件/usr/share/pyshared/horizon/templatetags/horizon.py中定义

 

@register.inclusion_tag('horizon/_subnav_list.html', takes_context=True)
def horizon_dashboard_nav(context):
    """ Generates sub-navigation entries for the current dashboard. """
    if 'request' not in context:
        return {}
    dashboard = context['request'].horizon['dashboard']
    panel_groups = dashboard.get_panel_groups()
    non_empty_groups = []

    for group in panel_groups.values():
        allowed_panels = []
        for panel in group:
            if callable(panel.nav) and panel.nav(context):
                allowed_panels.append(panel)
            elif not callable(panel.nav) and panel.nav:
                allowed_panels.append(panel)
        if allowed_panels:
            non_empty_groups.append((group.name, allowed_panels))

    return {'components': SortedDict(non_empty_groups),
            'user': context['request'].user,
            'current': context['request'].horizon['panel'].slug,
            'request': context['request']}

 

 

 

菜单位置：

/usr/share/pyshared/horizon/dashboards/syspanel/dashboard.py

文件全部内容

from django.utils.translation import ugettext_lazy as _

import horizon

class SystemPanels(horizon.PanelGroup):
    slug = "syspanel"
    name = _("System Panel")
    panels = ('overview', 'instances', 'services', 'flavors', 'images',
              'projects', 'users', 'quotas',)

 

class Syspanel(horizon.Dashboard):
    name = _("Admin")
    slug = "syspanel"
    panels = (SystemPanels,)
    default_panel = 'overview'
    roles = ('admin',)

horizon.register(Syspanel)

 

 

菜单显示的名字不在上述文件中，而在相应模块的panel.py中

/usr/share/pyshared/horizon/dashboards/syspanel/quotas/panel.py

 

from django.utils.translation import ugettext_lazy as _

import horizon
from horizon.dashboards.syspanel import dashboard

class Quotas(horizon.Panel):
    name = _("Quotas")    菜单显示名字
    slug = 'quotas'    与dashboard.py中保持一致

dashboard.Syspanel.register(Quotas)
