[英]Django JsonResponse with context
Can I use function JsonResponse and return.json file with dict context?我可以在字典上下文中使用 function JsonResponse 和 return.json 文件吗? I have only one.html and if I click in href ajax will get.json file and switch div's.
我只有一个。html 如果我点击href ajax 将得到.json 文件并切换div。
html: html:
<form id='FormSite' method="POST">
{% csrf_token %}
<div id='Bilboard'>
<div id='Pic'>
<video id='VideoStart' style="width: 100%; height: 100%;" autoplay preload="true" loop >
<source src="static/video/mainVideo.mp4"poster="static/img/facebook.png" type='video/mp4'>
Your browser does not support the video tag.
</video>
</div>
<div id='Wpis'>
<h1 id='HeaderWpis'>Aktualności:</h1>
<div id='WpisChild'>
{% for News in Messags %}
<div id='NewsPapper'>
<p style="font-size: 200% !important;">{{ News.title }}</p>
<img src="static/img/line.png" style="width: 5%; height: 5%; position: relative !important; left: 50%; transform: translateX(-50%);">
<p style="font-size: 150% !important;">{{ News.text |linebreaksbr }}</p>
<img src="static/img/line.png" style="width: 5%; height: 5%; position: relative !important; left: 50%; transform: translateX(-50%);">
<p style="font-size: 150% !important;">{{ News.Data }}</p>
</div>
{% endfor %}
</div>
</div>
</div>
</form>
views.py视图.py
def FirstStart(request):
if request.method == 'POST':
respone = {}
UrlCut = request.GET.get('site','')
if(len(UrlCut) > 0):
File_read_to_div = open('templemates/'+UrlCut+'.txt','r')
else:
File_read_to_div = open('templemates/Main.txt','r')
respone['Pic'] = str(File_read_to_div.readline())
respone['h1'] = str(File_read_to_div.readline())
respone['WpisChild'] = str(File_read_to_div.readline())
#r
Messages = NewsMessage.objects.all().order_by('-Data')
context = {
"Messags" : Messages
}
return JsonResponse(respone, context)
Messages = NewsMessage.objects.all().order_by('-Data')
context = {
"Messags" : Messages
}
return render(request, 'main.html', context)
ajax ajax
$.ajax({
url: url,
data: $('#FormSite').serialize(),
type: "POST",
async:false,
success: function(response) {
$($("#Pic").first()).replaceWith($(response['Pic']));
$("#HeaderWpis").text(response['h1'])
$($("#WpisChild").first()).replaceWith($(response['WpisChild']))
},
error: function()
{
alert('Bad connection');
}
});
So, if I first load main.html {{ News.title }} etc. work.所以,如果我首先加载 main.html {{ News.title }} 等工作。 But If ajax/django load this site from.txt he can't find context and display error function.
但是如果 ajax/django 从.txt 加载这个站点,他找不到上下文并显示错误 function。
JsonResponse doesn't take context as a parameter. JsonResponse 不将上下文作为参数。
https://docs.djangoproject.com/en/3.0/ref/request-response/#jsonresponse-objects https://docs.djangoproject.com/en/3.0/ref/request-response/#jsonresponse-objects
The first parameter, data, should be a dict instance.
第一个参数 data 应该是一个 dict 实例。 If the safe parameter is set to False (see below) it can be any JSON-serializable object.
如果安全参数设置为 False(见下文),它可以是任何 JSON 可序列化 object。
>>> from django.http import JsonResponse
>>> response = JsonResponse({'foo': 'bar'})
>>> response.content
b'{"foo": "bar"}'
In your case, you should be able to add messages to your dictionary:在您的情况下,您应该能够将消息添加到您的字典中:
respone['messages'] = NewsMessage.objects.all().order_by('-Data')
return JsonResponse(respone)
