当我尝试通过Ajax(jQuery)将数组发送到Django时
JavaScript代码:
new_data = ['a','b','c','d','e'];
$.get('/pythonPage/', {'data': new_data},function(data){});
我试着读取数组:
蟒蛇:
request.GET.get("data[]")
我只得到最后一个数组值:
'e'
我究竟做错了什么？
我正在尝试检测摇动 - 我正在使用以下代码,它工作得非常好,但在某些设备(例如Galaxy note 2)中它会很快检测到震动(在某些情况下 - 当我只是握住手机还是)
main.java:
ShakeListener mShaker = new ShakeListener(this);
mShaker.setOnShakeListener(new ShakeListener.OnShakeListener () {
public void onShake()
{
// Some code...
}
});
}
ShakeListener.java:
package com.my.app;

import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;

private static final int FORCE_THRESHOLD = 700;
private static final int TIME_THRESHOLD = 100;

private static final int SHAKE_DURATION = 1000;
private static …我正试图遵循以下解释:https: //developers.google.com/appengine/docs/python/tools/uploadingdata#Downloading_and_Uploading_All_Data
但是当我添加到我的app.yaml时:
- url: /remote_api
script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
login: admin
并尝试更新我的应用程序,我得到:
解析yaml文件时出错:无效对象:无法使用CGI处理程序启用threadsafe:$ PYTHON_LIB/google/appengine/ext/remote_api/handler.py
错误.
我究竟做错了什么？
谢谢!
顺便说一句,这是我的app.yaml:

当我尝试设置"%23"instand为"#"(example.com/%23TEST)的按钮时- 它会在计数框中单独计算每个哈希值.
有没有办法把一个像哈希的按钮 - 并仍然计算没有哈希的网址？
谢谢!
是否可以向后追溯整个querySet的ForeignKey关系？
我的意思是这样的:
x = table1.objects.select_related().filter(name='foo')
x.table2.all()
当table1将ForeignKey用于table2时.
在 https://docs.djangoproject.com/en/1.2/topics/db/queries/#following-relationships-backward 我可以看到它只适用于get()而不是filter()
谢谢
