在Django中使用原始SQL

-1

我最近從PHP遷移到django。我正在創建一個在Django上工作的項目..我習慣於在PHP中編寫自定義sql，因此我想使用raw（）在django中過濾來自我的數據庫的結果。在Django中使用原始SQL

但是我不能夠完全理解Django是如何運作..

請在下面找到我的代碼。

目前我收到下面提到的輸出

[('11677795635',), ('12345',)]

我想用一些在下文提到的格式環和印刷效果。

可以請你幫我如何for循環在Django ..

在PHP中，
同樣有可能通過

$query=mysql_query("SELECT abcdashboard_customerinfo.customerbuyingid FROM abcdashboard_customerinfo WHERE abcdashboard_customerinfo.customerbuyingid in (select DISTINCT abcdashboard_orders.customerid from abcdashboard_orders)"); 
$queryrun=mysql_num_rows($query);  
for ($f=0; $f <$queryrun; $f++) 
    { 
     ${'customer'.$f}=mysql_result($query,$f, 'customerbuyingid'); 
     echo ${'customer'.$f}; 
    }

models.py

class customerinfo(models.Model): 
    customerbuyingid = models.CharField(max_length=300, default='invalid customer id in database') 
    customername = models.CharField(max_length=300, default='invalid customer name in database') 
    customerphonenumber = models.CharField(max_length=12, default='0000000000') 
    customermailid= models.CharField(max_length=80, default='[email protected]') 

class orders(models.Model): 
    orderid = models.CharField(max_length=200) 
    orderstatus = models.CharField(max_length=10) 
    externalpurchaseid = models.CharField(max_length=100) 
    externalstatus = models.CharField(max_length=100) 
    customerid = models.CharField(max_length=100) 
    ops = models.CharField(max_length=100) 
    orderdate = models.DateField() 
    updatedon = models.DateTimeField(default=timezone.now)

views.py

def index(request): 
    all_customer = customerinfo.objects.all() 
    cursor = connection.cursor() 
    cursor.execute('''SELECT abcdashboard_customerinfo.customerbuyingid FROM abcdashboard_customerinfo WHERE abcdashboard_customerinfo.customerbuyingid in (select DISTINCT abcdashboard_orders.customerid from abcdashboard_orders) ''') 
    row = cursor.fetchall() 
    print (row) 
    context = {"row": row} 
    return render(request, "abcdashboard/index.html", context)

的Index.html

<html> 
<head> 
    <title> 

    </title> 

</head> 

<body> 
    <ul> 
<h2 align="center"> SQL Queries display </align> </h2> 

{% block content %} 

{{ row }} 

{% endblock %} 
    </ul> 

</body> 

</html>

不要這樣做。如果你想編寫Django，你應該編寫Django –

只需更換：

在views.py

：

row = cursor.fetchall() 
print (row) 
context = {"row": row}

有：

ids = [] 
for row in cursor.fetchall(): 
    id = row[0] 
    ids.append(id) 
context = {'rows': ids} 
...

index.html中：

{{ row }}

與

{% for id in rows %} 
{{ id }} 
{% endfor %}
