在单页上处理不同形式的 post 请求 -Django
handling different forms post request on single page -Django
我是新手,正在做网站。在这个网站上,我创建了管理面板来管理不同的产品和属性。
我有一个名为 size.html 的页面,我应该更改它的名称并使其成为 productAtributes.html 并且在这个页面上,我想对不同的产品属性执行所有 添加、更新、删除 操作。
我的代码如下:
models.py
class Product(models.Model):
prod_ID = models.AutoField("Product ID", primary_key=True)
prod_Name = models.CharField("Product Name", max_length=30, null=False)
prod_Desc = models.CharField("Product Description", max_length=2000, null=False)
prod_Price = models.IntegerField("Product Price/Piece", default=0.00)
prod_img = models.ImageField("Product Image", null=True)
def __str__(self):
return "{}-->{}".format(self.prod_ID,
self.prod_Name)
class Size(models.Model):
size_id = models.AutoField("Size ID", primary_key=True, auto_created=True)
prod_size = models.CharField("Product Size", max_length=20, null=False)
def __str__(self):
return "{size_id}-->{prod_size}".format(size_id=self.size_id,
prod_size=self.prod_size)
class Color(models.Model):
color_id = models.AutoField("Color ID", primary_key=True, auto_created=True)
prod_color = models.CharField("Product Color", max_length=50, null=False)
def __str__(self):
return "{color_id}-->{prod_color}".format(color_id=self.color_id,
prod_color=self.prod_color)
class PaperChoice(models.Model):
paper_id = models.AutoField("Paper Choice ID", primary_key=True, auto_created=True)
paper_choices_name = models.CharField("Paper Choices", max_length=50, null=False)
def __str__(self):
return "{}-->{}".format(self.paper_id,
self.paper_choices_name)
views.py
from django.core.paginator import Paginator, PageNotAnInteger, EmptyPage
from django.shortcuts import render, redirect
from user.models import *
def size(request):
if request.method == 'POST':
size_store = request.POST['prod_size']
size_update = Size(prod_size=size_store)
size_update.save()
return redirect('/admin1/productSize')
else:
size_show = Size.objects.all()
# start paginator logic
paginator = Paginator(size_show, 3)
page = request.GET.get('page')
try:
size_show = paginator.page(page)
except PageNotAnInteger:
size_show = paginator.page(1)
except EmptyPage:
size_show = paginator.page(paginator.num_pages)
# end paginator logic
return render(request, 'admin1/size.html', {'size_show': size_show})
def size_edit(request, id):
size_edit = Size.objects.filter(size_id=id)
return render(request, 'admin1/size.html', {'size_edit': size_edit})
def size_edit_update(request, id):
if request.method == 'POST':
size_store = request.POST['prod_size']
size_update = Size(size_id=id, prod_size=size_store)
size_update.save()
return redirect('/admin1/productSize')
def size_delete(request, id):
size_deletee = Size.objects.filter(size_id=id)
size_deletee.delete()
return redirect('/admin1/productSize')
当我为 Size 创建 添加、更新、删除 功能时,我将对 color 做同样的事情 和 纸张选择。

为了执行 views.py 的操作,我创建了 size.html .Nut 10 到 12 产品属性,对于这些属性我不想创建单独的 html 页面.
我想对单个 html 页面中的所有属性进行所有操作。可能吗?
意味着根据属性类型请求页面数据应该动态变化,我不必为每个属性创建单独的模板页面。
您需要在您的视图中制作表单,而不是模板,我不确定这是否是最佳做法,但这是我认为您可以做到这一点的唯一方法,(使用 Class-Based Views 会简化这个过程很多)但是如果你想坚持功能,这就是你要做的。
让我们输入一行:
<label>Product Size:</label>
<input type="text" name="prod_size" class="form-control w-50"><br>
让我们使用 Django 的标签并将其变成这样:
<label>{{form.display_name}}:</label>
<input type="text" name="{{form.name}}" class="form-control w-50">
class 可能相同,但您可以将相同的功能扩展到 class 或类型字段。
在后端,您想列出所有要显示的元素,并带有嵌套字典:
forms = [ # Each form
[ # Each field within the form, this way, you can have a different amount each time
{'display_name': 'Product Size', # label Display name
'name': 'prod_size'}, # name tag value
{'display_name': "it's value", # This is a different field
'name': 'just an example'}
],
]
然后你可以在模板中做一个for循环:
{% for form in forms %}
{$ for field in form %}
<label>{{field.display_name}}:</label>
<input type="text" name="{{field.name}}" class="form-control w-50">
我不太确定你想在你的代码中做什么,所以我没有让这个例子太具体,但希望它能给你灵感,让你走上正确的轨道,如果您需要更多帮助,只需询问
