Django4全栈进阶之路23 项目实战（报修类型表）：应用程序命名空间app_name和分页组件paginator

1、应用程序命名空间app_name

from django.urls import path
from . import views
from .views import RepairDetailView

app_name = 'repair'

urlpatterns = [
    path('repair_types/', views.RepairTypeListView.as_view(), name='repair_type_list'),
    path('repair_types/create/', views.RepairTypeCreateView.as_view(), name='repair_type_create'),
    path('repair_types/<int:pk>/update/', views.RepairTypeUpdateView.as_view(), name='repair_type_update'),
    path('repair_types/<int:pk>/delete/', views.RepairTypeDeleteView.as_view(), name='repair_type_delete'),]

2、模型

from django.db import models
from BaseApp.models import Department
from HRApp.models import Employee
from MyProject import settings
import uuid

class RepairType(models.Model):
    department = models.ForeignKey(Department, verbose_name="部门", on_delete=models.CASCADE, to_field='id',
                                   related_name='RepairType_department')
    name = models.CharField(verbose_name="类型", max_length=100)
    parent = models.ForeignKey('self', verbose_name="父级", null=True, blank=True, on_delete=models.CASCADE,
                               related_name='RepairType_parent')
    created_by = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name="创建账户", on_delete=models.CASCADE,
                                   related_name='repair_types_created')
    created_at = models.DateTimeField("创建时间", auto_now_add=True)
    updated_by = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name="修改账户", on_delete=models.CASCADE,
                                   related_name='repair_types_update')
    updated_at = models.DateTimeField("修改时间", auto_now=True)

    def __str__(self):
        return self.name

    class Meta:
        verbose_name = "报修类型"
        verbose_name_plural = "报修类型"
        ordering = ['department', 'name']

3、表单

from django import forms
from .models import Department, RepairType, Repair

class RepairTypeForm(forms.ModelForm):
    class Meta:
        model = RepairType
        # fields = '__all__'
        fields = ['name', 'parent', 'department']
        parent = forms.ModelChoiceField(queryset=RepairType.objects.all().order_by('name'), required=False)

4、模板

list.html

{% extends 'base.html' %}

{% block content %}
    <div class="container-fluid mt-3">
        <div class="row">
            <div class="col-md-12">
                <h3 class="mb-3">维修类型列表</h3>
                <a href="{% url 'repair:repair_type_create' %}" class="btn btn-primary mb-2">新增</a>
                <div class="table-responsive">
                    <table class="table table-striped table-hover">
                        <thead>

                            <th>归属部门</th>
                            <th>类型名称</th>

                            {#                            <th>创建时间</th>#}
                            {#                            <th>修改账号</th>#}
                            {#                            <th>最后修改时间</th>#}
                            <th>操作</th>
                        </tr>
                        </thead>
                        <tbody>
                        {% for repair_type in repair_types %}
                            <tr>

                                {#                                <td>{{ repair_type.created_time }}</td>#}
                                {#                                <td>{{ repair_type.modified_by }}</td>#}
                                {#                                <td>{{ repair_type.modified_time }}</td>#}
                                <td>
