基于模板：使用基于Slug的动态URL模式通过Ajax在Django中加载动态内容

时间：2019-02-05 07:46:28

标签： python ajax django python-3.x

通过模板标签“ include”或基于“ Ajax”的加载来加载（包括）动态内容时遇到的问题。

如Here所述，有三种方法可以做...但是仍然有问题

使用Django 2.1.3，Python 3.6 ...

我尝试了两种方法： 1.使用“包含”标签 2.通过Ajax加载

Python

views.py 
def equity(request,symbol):

    """
    some code
    """

    context_all = {
    'template_Name': ('/autoRefreshEqu/{}/').format(symbol)
        }
    template = loader.get_template('equity/equity.html')
    response_body = template.render(context_all,request)
    return HttpResponse(response_body)

def autoRefreshEqu(request,symbol):

    """
    code for generating context
    """

    context_all = {
    'quote':quote,
    'changeQuote':changeQuote,
    'lastPrice': x['data'][0]['change'],
    'change':x['data'][0]['change'],
    'pChange':x['data'][0]['pChange'],
    'lastUpdateTime': x['lastUpdateTime'],

    }

template = loader.get_template('equity/autorefequ.html')
response_body = template.render(context_all,request)
return HttpResponse(response_body)
urls.py 
path('autoRefreshEqu/<slug:symbol>/',views.autoRefreshEqu, name="autoRefreshEqu"),

path('equity/<slug:symbol>/',views.equity, name="equity"),

HTML部分

equity / equity.html

假设我将URL称为

/ equity / EICHERMOT /

然后模板应调出

/ autoRefreshEqu / EICHERMOT /

并渲染到主要资产模板。

具有id = autoupdate的div应该具有由autoRefreshEqu生成的所有上下文。

谢谢。

答案 0 :(得分：1)

我不确定您为什么要通过{% url %}标记传递URL。这是为了获取URL模式名称并将其转换为URL。您已经有一个完整的URL，因此您可以直接使用它：

<script>$("#autoupdate").load("{{ template_Name }}");</script>

当然，这并不是做事情的好方法。您应该使用{% url %}，而不是在视图中硬编码URL。删除该template_Name变量，然后传递symbol；然后，在模板中：

<script>$("#autoupdate").load("{% url "autoRefreshEqu" symbol=symbol %}");</script>
