dajaxice錯誤'str'對象沒有屬性'has_header'

Question

我試圖使用dajaxice刷新我的表，但我看到一個錯誤。

回溯：

Environment: 


Request Method: GET 
Request URL: http://127.0.0.1:8000/bank/index1/

Traceback:

    187.     response = middleware_method(request, response)

Exception Type: AttributeError at /bank/index1/ 
Exception Value: 'str' object has no attribute 'has_header' 

這是我的看法：

def index1(request): 

    data = MelliTable(ModelMelli.objects.filter(check=False)) 
    RequestConfig(request, paginate={'per_page': 20}).configure(table) 
    table = render_to_string('meli/index.html', {'data': data }) 
    return simplejson.dumps({'table':table}) 
dajaxice_functions.register(index1) 

而我的JS是：

<script> 
function my_callback(data){ 
    if(data!=Dajaxice.EXCEPTION){ 
     document.getElementById('test').innerHTML = data.table; 
    } 
    else{ 
     alert('Error'); 
    } 
} 
</script> 

Answer 1

django-dajaxice作品包裝視圖功能，在這裏你的代碼index1，與特殊處理程序;並通過動態匹配的網址代替/bank/index1/提供服務。
因此，您不必爲index1定義urlpattern /bank/index1/，只需通過Dajaxice interface即可訪問它，也許這裏是Dajaxice.bank.index1(my_callback)。

錯誤是由一個普通的Django視圖將返回一個HttpResponse()實例的原因造成的，而index1這裏返回一個字符串（當您通過dajaxice接口調用，上面提到的特殊處理程序會把字符串的HttpResponse W/O問題）

Answer 2

我改變我的觀點，並把dajaxice功能ajax.py，這是我的js調用它：

<script> 
function setupRefresh() { 
    setTimeout("Dajaxice.meli.refresh(my_callback)", 5000); // milliseconds 
} 
</script> 

我看到劇本叫我djaxice在控制檯，但我不知道我應該在my_callback js函數中寫什麼換桌子！

觀點：

def index2(request): 

    table = MelliTable(ModelMelli.objects.filter(check=True)) 

    #table.paginate(page=request.GET.get('page', 1), per_page=4) 
    RequestConfig(request, paginate={'per_page': 20}).configure(table) 
    return render(request, 'meli/index1.html', {'table': table }) 

AJAX：

def refresh(request): 
    message = "" 
    table = MelliTable(ModelMelli.objects.filter(check=True)) 
    RequestConfig(request, paginate={'per_page': 20}).configure(table) 
    table1 = render_to_string('meli/index.html', {'table': table, 'message': message }) 
    return simplejson.dumps({'table1':table1}) 

dajaxice_functions.register(refresh) 

和我的模板是：

{% extends "meli/base.html" %} 
{% load render_table from django_tables2 %} 
{% block content %} 
<script> 
function setupRefresh() { 
    setTimeout("Dajaxice.meli.refresh(my_callback)", 5000); // milliseconds 
} 
</script> 

      {% render_table table %}    
{% endblock %}
