如何将单个 Django 模板用于多种用途

Question

我有不同的 django 模型，它们是相同的，例如

• 项目类别
• 库存类别
• 菜单类别
• 费用类别

所有这些模型都具有相同的属性。

我想使用单个 html 页面，即 category_list.html 将这些模型显示为列表。我不想使用不同的页面，如 item_category_list.html、inventroy_category_list.html、menu_category_list.html 等。每个页面都包含 page header，这是 h1 标签中表示的页面的实际标题。我想针对当前加载的页面进行更改。

注意：我正在使用通用视图来列出项目，我目前正在使用上下文来识别哪个视图正在发送响应。

任何帮助将不胜感激。

views.py

class ItemCategoryList(ListView):
    model = ItemCategory
    template_name = 'app/category_list.html'

    def get_context_data(self, **kwargs):
        # Call the base implementation first to get a context
        context = super().get_context_data(**kwargs)
        # Add in a QuerySet of all the books
        context['page'] = 'Item'
        return context


class InventoryCategoryList(ListView):
    model = InventoryCategory
    template_name = 'app/category_list.html'


class ExpenseCategoryList(ListView):
    model = ExpenseCategory
    template_name = 'app/category_list.html'

models.py

class ItemCategory(models.Model):
    name = models.CharField(max_length=30)
    description = models.CharField(max_length=300, null=True, blank=True)
    image = models.ImageField(upload_to="uploads/item_categories/", null=True, blank=True)
    is_active = models.BooleanField(default=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now_add=True)


class InventoryCategory(models.Model):
    name = models.CharField(max_length=30)
    description = models.CharField(max_length=300, null=True, blank=True)
    image = models.ImageField(upload_to="uploads/inventory_categories/", null=True, blank=True)
    is_active = models.BooleanField(default=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now_add=True)

class ExpenseCategory(models.Model):
    name = models.CharField(max_length=30)
    description = models.CharField(max_length=300, null=True, blank=True)
    image = models.ImageField(upload_to="uploads/expense_categories/", null=True, blank=True)
    is_active = models.BooleanField(default=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now_add=True)

Answer 1

不是基于类，但我的解决方案是：

models.py：

class Category(models.Model):
    name = models.CharField(max_length=30)
    description = models.CharField(max_length=300, null=True, blank=True)
    image = models.ImageField(upload_to="uploads/categories/", null=True, blank=True)
    is_active = models.BooleanField(default=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now_add=True)

urls.py:

url(r'^(?P<category>\w+)/$', views.ItemCategoryList, name='category')

home.html:

<a href="{% url 'category' 'ItemCategory' %}">Item Category</a>
<a href="{% url 'category' 'InventoryCategory' %}">Inventory Category</a>

category_list.html：

{% block title %}{{category.name}}{% endblock %}

{% for l in list %}
    {{l}}
{% endfor%}

views.py：

def ItemCategoryList(request, category):
    list = Category.objects.filter(name=category)
    category = category
    context{
      'list':list,
      'category':category
           }
    return render(request, 'app/category_list.html',context)
