我想要的是获取登录用户的所有网站。我尝试了很多东西，但没有一个在起作用。我仍然不确定将代码，存储库或控制器放在哪里......

我已经阅读了有关Laravel中的数据透视的教程，我在repo中试过了类似的东西，但它不起作用......

$user = $this->user->find(auth()->user()->id); //This line is working

foreach ($user->sites as $site) {
    return $site
    ->latest()
    ->paginate($n);
}

Answer 1

所以你所做的事情似乎非常接近。

所以你几乎拥有它，当迭代它们应该是站点模型的实例时。

from traits.trait_base import ETSConfig
#ETSConfig.toolkit = "wx"
# fix window color on unity TODO: gets overriden by splitter
if ETSConfig.toolkit == "wx":
    from traitsui.wx import constants
    constants.WindowColor = constants.wx.NullColor

import optparse, logging, urlparse

from capture import BaseCapture, DummyCapture
from bullseye import Bullseye
from process import Process

def main():
   p = optparse.OptionParser(usage="%prog [options]")
   p.add_option("-c", "--camera", default="any:",
           help="camera uri (none:, any:, dc1394://guid/b09d01009981f9, "
                "fc2://index/1, replay://glob/beam*.npz) [%default]")
   p.add_option("-s", "--save", default=None,
           help="save images accordint to strftime() "
                "format string (e.g. 'beam_%Y%m%d%H%M%S.npz'), "
                "compressed npz format [%default]")
   p.add_option("-l", "--log",

   p.add_option("-d", "--debug", default="info",
           help="log level (debug, info, warn, error, "
                "critical, fatal) [%default]")
   opts, args = p.parse_args()
   logging.basicConfig(filename=opts.log,
           level=getattr(logging, opts.debug.upper()),
           format='%(asctime)s %(levelname)s %(message)s')
   scheme, loc, path, query, frag = urlparse.urlsplit(opts.camera)
   if scheme == "opencv":
       from .opencv_capture import OpenCVCapture
       if loc == "index":
          cam = OpenCVCapture(int(path[1:]))
   elif scheme == "none":
       from capture import DummyCapture
          cam = DummyCapture()
   elif scheme == "any":
       try:
          from .opencv_capture import OpenCVCapture
          cam = OpenCVCapture()
       except Exception, e:
          logging.debug("opencv error: %s", e)
          from capture import DummyCapture
          cam = DummyCapture()
  logging.debug("running with capture device: %s", cam)
  if opts.save:
      cam.save_format = opts.save
  proc = Process(capture=cam)
  bull = Bullseye(process=proc)
  bull.configure_traits()
  bull.close()

if __name__ == "__main__":
    main()

唯一看起来有点奇怪的是你如何定义枢轴。通常在调用$user = auth()->user(); // This is a way of saying your first line without a db query for the user foreach ($user->sites as $site) { // each site in here is a site model $site->pivot->relation; }时，您不会定义连接ID，如果您希望改变默认值，可以将其作为参数传递给withPivot，如此。

belongsToMany

Answer 2

如果您希望所记录用户的所有网站都这样做：

$sites = Auth::user()->sites;

这就是你到达这些网站所需要做的一切。如果你想使用查询和分页，请尝试这样：

$sites = Auth::user()->sites()->latest()->paginate($n);
