如何在iPhone上隐藏地址栏？

到目前为止我尝试了两种不同的方法

• 在页面加载时使用JavaScript向下滚动一个像素技巧

• 以下元标记:

  <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" /><meta name="apple-mobile-web-app-capable" content="yes" />
  

  Run Code Online (Sandbox Code Playgroud)

这个:

<meta names="apple-mobile-web-app-status-bar-style" content="black-translucent" />

我完全糊涂了.

PS:哦,我忘了一个非常重要的事情:网页本身不会溢出浏览器窗口.这可能是1像素滚动技巧不起作用的原因.

我无法做大,因为关于设计的热门话题,每个人都可以滚动,但这个页面折叠... :)

django中的型号:

class Key(models.Model):
    id     = models.AutoField(primary_key=True, blank=True)
    name   = models.CharField(max_length=50)


class Record(models.Model):
    id         = models.AutoField(primary_key=True, blank=True)
    project_id = models.IntegerField()
    name       = models.CharField(max_length=50)


class Value(models.Model):
    id        = models.AutoField(primary_key=True, blank=True)
    record    = models.ForeignKey(Record)
    key       = models.ForeignKey(Key)
    value     = models.CharField(max_length=255)

我需要从DB中选择这个数据:

NAME (from record)
and fields related with this record
[NAME (from key), VALUE (from value)]
[NAME (from key), VALUE (from value)]
[...]

我可以使用django ORM进行此选择吗？(例如在SQL select中看起来像这样)

SELECT
    `keeper_record`.`id` AS `record_id`,
    `keeper_record`.`name` AS `name`,
    `keeper_record`.`desc` AS `desc`,
    `keeper_key`.`name` AS `key_name`,
    `keeper_key`.`desc` AS `key_desc`,
    `keeper_value`.`value` …

嗨,有Stackoverflow黑客!

我有一个非常小的问题,或者我和C syslog()函数之间的误解.

代码编译得很好,我可以看到它正在做它的"虚拟工作"(ping 8.8.8.8),但是定义的日志不会附加.我对此完全感到困惑,并且不知道可能出现什么问题.已经SMAO(搜索我的屁股 - 尝试推广它),但只是无法让它正常工作.

代码在这里:

#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
#include <syslog.h>
#include <string.h>

// Application settings # TODO: import these from a .ini file

#define WORKDIR   "/var/run/management"
#define LOGDIR    "/var/log/management"
#define LOGFILE   "/var/log/management.log"
#define SCRIPTDIR "/var/spool/management"
#define PIDFILE   "/var/run/management/daemon.pid"

int main(void) {
  printf("Management Daemon\nInitializing...");
  pid_t pid, sid;

  setlogmask(LOG_UPTO (LOG_NOTICE));
  openlog(LOGFILE, LOG_CONS | LOG_PID | LOG_NDELAY, LOG_LOCAL1);
  syslog(LOG_NOTICE, "Management Daemon started by User %d", getuid());
  closelog();

  printf("Done.\nForking...\n");

  pid …
