是否有任何选项可以在CodeIgniter中获取新记录的最后一个插入ID？
$last_id = $this->db->insert('tablename',
array('firstcolumn' => 'value',
'secondcolumn' => 'value')
);
考虑表格的字段id(autoincrement)firstcolumn和secondcolumn.
这样您就可以在以下代码中使用insert id.
这可能是之前被问过的,但我似乎无法找到答案.我已经从Windows迁移到Linux并且最近开始使用PyDev(Aptana),但我似乎无法找到的是如何查找函数的所有引用.
根据docker文档,我尝试使用redis对python应用程序进行了非常简单的首次测试.这会在一段时间后崩溃,因为redis无法持续存在.我不知道为什么.你可以在这里找到公共回购:Github repo
我目前的docker-compose.yml是:
web:
build: .
ports:
- "5000:5000"
volumes:
- .:/code
links:
- redis
redis:
image: redis:latest
volumes:
- ./data:/data

我正在使用Blocktrail API中的webhook来“监听”事件，即接收地址上的硬币。
现在，当事件发生时，API会对我的URL进行POST。这应该向通过socket.io连接到我的服务器的浏览器发送一条消息（例如“在区块链上看到付款”）
所以问题是
我如何使用flask-socketio将消息从路由发送到套接字
伪代码：
@app.route('/callback/<address>')
def callback(id):
socketio.send('payment seen on blockchain')
@socketio.on('address',address)
def socketlisten(address):
registerCallback(address)
我有下面的代码，试图让产品返回所有相关属性。
我没有收到任何错误，但我在“prod”变量中没有看到任何属性。
private void frmProductDetail_Load(object sender, EventArgs e)
{
MagentoService service = new MagentoService();
MagentoServiceHelper help = MagentoServiceHelper.Instance;
catalogAttributeEntity[] attributes = service.catalogProductAttributeList(help.SessionID, AttributeSet); //AttributeSet is a property of the form
catalogProductRequestAttributes att = new catalogProductRequestAttributes();
string[] attlist = new string[attributes.Length];
for (int i = 0; i < attributes.Length; i++)
{
attlist[i] = attributes[i].code;
}
att.attributes = attlist;
catalogProductReturnEntity prod = service.catalogProductInfo(help.SessionID,
ProductId, "default", att, "sku"); //ProductId is a property of the form
}
我想只转储一个表,但从它的外观来看,没有参数.
我找到了转储的这个例子,但是适用于所有表:
# Convert file existing_db.db to SQL dump file dump.sql
import sqlite3, os
con = sqlite3.connect('existing_db.db')
with open('dump.sql', 'w') as f:
for line in con.iterdump():
f.write('%s\n' % line)
在下面的文件中,文件apprequirements.txt已添加到容器中.我知道因为pip install有效.但是,myworker.py不会复制/添加该文件.为什么？
FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD ./frontend/apprequirements.txt /code
RUN pip install -r apprequirements.txt
ADD ./backend/myworker.py /code
我用docker-compose运行它,你可以在https://github.com/AvidSoftware-be/Docker-compose-test上看到整个例子
