django---inclusion_tag使用

1. 创建一个 templatetags文件夹(一定叫这个)

2. 在里面创建一个py文件(名字随便起) 比如 project

3. 在py文件中书写代码

from django.template import Library
from web import models
from django.urls import reverse


register = Library()


@register.inclusion_tag('inclusion/all_project_list.html')
def project_list(request):
    # 我创建的
    my_project_list = models.Project.objects.filter(creator=request.tracer.user)
    # 我参加的
    join_project_list = models.ProjectUser.objects.filter(user=request.tracer.user)

    return {'my': my_project_list, 'join': join_project_list}


@register.inclusion_tag('inclusion/manage_menu_list.html')
def manage_menu_list(request):
    data_list = [
        {'title': '概览', 'url': reverse("dashboard", kwargs={'project_id': request.tracer.project.id})},
        {'title': '问题', 'url': reverse("issues", kwargs={'project_id': request.tracer.project.id})},
        {'title': '统计', 'url': reverse("statistics", kwargs={'project_id': request.tracer.project.id})},
        {'title': 'wiki', 'url': reverse("wiki", kwargs={'project_id': request.tracer.project.id})},
        {'title': '文件', 'url': reverse("file", kwargs={'project_id': request.tracer.project.id})},
        {'title': '配置', 'url': reverse("setting", kwargs={'project_id': request.tracer.project.id})},
    ]
    for item in data_list:
        # 当前用户访问的URL：request.path_info:  /manage/4/issues/xxx/add/
        if request.path_info.startswith(item['url']):
            item['class'] = 'active'

    return {'data_list': data_list}

4. 使用 

4.使用 先在前端界面加载一下 

{% load project %}

5.然后就可以使用了      
       
{% manage_menu_list request %}
