Django over Postgresql：使用原始SQL插入和返回語句不起作用

Question

結合使用Django的Postgresql 9.3 + PostGIS，我試圖將記錄輸入到表中並返回給定的id，如下所示

def join(request):
    from django.db import connection, transaction
    cursor = connection.cursor()
    id = cursor.execute("insert into table1 values(DEFAULT, 'temp', null,-4, null,null, null, null, DEFAULT, 1,null,DEFAULT,DEFAULT, null) returning id")
    transaction.set_dirty()

    return HttpResponse(id)

這將返回None ，我如何獲得從sql查詢返回的id

Answer 1

from django.db import connection, transaction

def join(request):
    cursor = connection.cursor()
    id = cursor.execute("insert into table1 values(DEFAULT, 'temp', null,-4, null,null, null, null, DEFAULT, 1,null,DEFAULT,DEFAULT, null)")
    transaction.set_dirty()
    last_id = connection.insert_id()
    return HttpResponse(str(last_id))

Answer 2

您的數據庫后端是什么？ 如果您使用sqlite3，

def join(request):
    from django.db import connection, transaction
    cursor = connection.cursor()
    cursor.execute("insert into table1 values(DEFAULT, 'temp', null,-4, null,null, null, null, DEFAULT, 1,null,DEFAULT,DEFAULT, null)")
    cursor.execute("SELECT last_insert_rowid() FROM table1")
    id = cursor.fetchone()[0]
    transaction.set_dirty()

    return HttpResponse(id)
