如何在链接中传递变量到Django视图 [英] how to Pass variable in link to the django view

问题描述

我有一个HTML表单，该表单使用for循环显示数据.

I have a html form which display data using a for loop.

<tbody id="table">
    {% for sku, lid, stk, mrp, sp, stts in product_data %}
    <tr>
        <td>
            <a class="btn-link" href="/product/product.html" value="{{sku}}">{{sku}}</a>
        </td>
        <td>{{lid}}</td>
        .....

此代码使用for循环在表的第一个列的链接中打印表中的数据.
链接指向一个新页面，我希望在该页面上显示一些数据.
现在，显示的数据是从mongodb数据库动态生成的.我想要当我单击链接时，将值作为参数传递给django视图，因此可以获取包含该参数的数据并在下一页上显示.该怎么做?

This code prints data in a table using a for loop with a link in first colyumn of table.
The link points to a new page where i want some data to be displayed.
Now The displayed data is dynamically generated from a mongodb database. I want when i click on the link it pass the value as a parametre to a django view so can fetch data which contains the parametre and show it on the next page. How to do that?

我的views.py:

My views.py:

from django.shortcuts import render
from django.http import HttpResponse
from inventory.models import GetProductData

def inventory(request):
    pd = GetProductData().skuData()
    sku = pd[0]
    listing_id = pd[1]
    stock_count = pd[2]
    mrp = pd[3]
    status = pd[5]
    selling_price = pd[4]

    product_data = zip(sku, listing_id, stock_count, mrp, selling_price, status)
    context_dict = {'product_data':product_data}
    return render(request, 'inventory/inventory.html', context_dict)

def product(request):
    return render(request, 'inventory/product.html')

推荐答案

首先，建议不要在添加URL时使用html名称.而不是拥有

First of all, its not advisable to use html name when you add a url. Instead of having

href="/product/product.html"

您本来可以拥有类似的东西

you could have just had something like

href="/product/"

因此，在您的urls.py中，应按以下说明对其进行定义

so in your urls.py you should have it defined as below

url(r'^product/$', product),

其中"product"是对应于该请求的视图.

where 'product ' is the corresponding view handling that request.

现在，如果您想从html向django发送一些参数

Now if you want to send some parameters to django from the html

按如下所示呈现您的模板

render your template as below

<tbody id="table">
    {% for sku, lid, stk, mrp, sp, stts in product_data %}
    <tr>
        <td>
            <a class="btn-link" href="/product/?sku={{ sku }}">{{sku}}</a>
        </td>
        <td>{{lid}}</td>
        .....

，并且在您看来，即；在产品上

and in your view i.e; at products

def product(request):
    if request.method=='GET':
        sku = request.GET.get('sku')
        if not sku:
            return render(request, 'inventory/product.html')
        else:
            # now you have the value of sku
            # so you can continue with the rest
            return render(request, 'some_other.html')
