我有一个开发数据库和一个实时数据库。我需要从实时数据库中返回一些结果，但仅针对此模型中的一种方法。
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class TableName extends Model
{
protected $table = 'table_name';
protected $connection = 'dev';
public $timestamps = false;
public static function live($index) {
$liveId = Settings::where('index', $index)->get()[0];
$live = new TableName;
$live->setConnection('live');
$data = $live::where('index', $liveId->live_index)->get();
dd($live);
return $data;
}
}
如果我dd()在$live打完电话后变量setConnection然后它说，连接确实live。但是，只要我dd()在$data我从一开始的行开发数据库！
显然我收到语法错误,但我没有看到我的代码有任何问题!
if rs.EOF then
'User doesn't exist, create the record
query = currentDate&",'"
query = query + password & "','"
query = query + "user', '"
query = query + email & "', '"
query = query + fname & "', '"
query = query + sname & "'"
handle = add_to_database("users","jdate,password,perms,email,fname,sname",query)
response.write handle
else
response.write "Error: User already exists, please use a different email address"
end if
这是add_to_database函数
function add_to_database(where,column,values)
'Create query
sql = "INSERT INTO " & where …试图检查我的ObservableCollection没有与我想要添加的对象匹配的对象.
例如:
public class LoggedUsers : NotifyUIBase
{
public ObservableCollection<Logged> UserList { get; private set; }
public LoggedUsers()
{
UserList = new ObservableCollection<Logged>();
}
public void Add(Logged user)
{
if (UserList.Where(x => x == user))
{
UserList.Add(user);
}
}
}
因此,如果ObservableCollection有一个Logged对象具有与之相同的属性值,Add(Logged user)那么我希望它不添加user.
编辑1:
public class LoggedUsers : NotifyUIBase
{
public ObservableCollection<Logged> UserList { get; private set; }
public LoggedUsers()
{
UserList = new ObservableCollection<Logged>();
}
public void Add(Logged user)
{
if (!UserList.Any(x => x == user)) …我目前在我的网站上集成了多个 Vue 实例，无法使整个网站成为 Vue 实例并使用组件，因为存在冲突的可能性和其他问题。
例如：
<!doctype html>
<html lang="en">

const data = [
{ value: 'BMW', count: 1 },
{ value: 'AUDI', count: 1 },
{ value: 'VAUXHALL', count: 1 },
{ value: 'FIAT', count: 1 },
{ value: 'HONDA', count: 1 },
{ value: 'LANDROVER', count: 1 },
];
const selected = [ 'AUDI', 'HONDA' ];
所以基本上上面会变成：
const data = [
{ value: 'AUDI', count: 1 },
{ value: 'HONDA', count: 1 },
{ value: 'BMW', count: 1 },
{ value: 'VAUXHALL', count: 1 },
{ value: …我已经修改了一些我在网上找到的圆形进度条的代码，它可以工作，直到进度条达到 100%，然后它就会消失......
我不知道出了什么问题，我假设这与 ArcSegment 的工作方式有关，但我不完全理解它背后的数学原理，有人能给我建议吗？
这是 ProgressBar 和 Slider：
<Slider Value="{Binding Source={StaticResource runtimeVariables}, Path=uploadProgress}" Maximum="100" Margin="0,0,252,0" />
<ProgressBar Width="150" Style="{StaticResource CircularProgress}" Value="{Binding Source={StaticResource runtimeVariables},Path=uploadProgress}" Maximum="100" HorizontalAlignment="Left" />
这是样式和转换器
<CircleProgress:StartPointConverter x:Key="StartPointConverter" />
<CircleProgress:ArcSizeConverter x:Key="ArcSizeConverter" />
<CircleProgress:ArcEndPointConverter x:Key="ArcEndPointConverter" />
<CircleProgress:LargeArcConverter x:Key="LargeArcConverter" />
<CircleProgress:SizeTextOnParent x:Key="SizeTextOnParent" />
<CircleProgress:Difference x:Key="Difference" />
<Style TargetType="ProgressBar" x:Key="CircularProgress">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ProgressBar">
<Grid x:Name="PathGrid" Width="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Width}">
<Canvas>
<DockPanel Height="{Binding ElementName=PathGrid, Path=Width}" Width="{Binding ElementName=PathGrid, Path=Width}">
<TextBlock x:Name="PathPercentage"
Text="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Value, StringFormat={}{0}%}"
Foreground="White"
FontSize="{Binding ElementName=PathGrid, Path=ActualWidth, Converter={StaticResource SizeTextOnParent}}"
VerticalAlignment="Center" …例如,如果我的2个日期相隔仅5天,我想显示5 Days Ago.
但是,如果他们相隔12天,我会显示1 week ago.
如果它们相隔大约29天,我会展示1 Month Ago.
但是,不同的月份有不同的天数,所以我的下面的代码将不起作用,我将如何做到这一点？
到目前为止我所拥有的:
switch(true) {
case (diff == 0):
difference = 'Today';
break;
case (diff < 7):
difference = diff + 'day' + (diff > 1 ? 's' : '') + ' ago';
case;
case (diff >= 7):
difference = (diff / 7) + 'week' + ((diff / 7) > 1 ? 's' : '') + ' ago';
break;
case (diff >= 28)
break;
}
我用来querySelectorAll选择 2 个select元素。然后，我将新创建的<option>元素附加到这两个<select>元素。
但是，由于某种原因，只有最后一个元素附加了选项，第一个元素由于某种原因被忽略。
这是我的代码：
displayLoading() {
let dropdowns = document.querySelectorAll('[data-search-select]');
let loadingOption = document.createElement('option');
loadingOption.innerHTML = 'Loading...';
for(let i = 0; i < dropdowns.length; i++) {
dropdowns[i].disabled = true;
dropdowns[i].innerHTML = '';
dropdowns[i].appendChild(loadingOption);
}
}
这是 HTML：
<div class="formgroup">
<label class="dropdown-search__label">Choose a make:</label>
<select name="dropdown-search__select--make" id="dropdown-search__select--make" data-search-select="make">
</select>
</div>
<div class="formgroup last">
<label class="dropdown-search__label">Choose a model:</label>
<select name="dropdown-search__select--model" id="dropdown-search__select--model" data-search-select="model">
</select>
</div>
我通常使用Eloquent,因此转置数据要容易得多.但是我在香草PHP中苦苦挣扎.
我尝试过array_map(null, ...$array)因为它不是一个数组而得到错误.
我有以下键控数组:
[
'email' => [
"william.pool@gmail.com",
"martynleeball@gmail.com"
],
'lastName' => [
'Pool',
'Ball'
],
'firstName' => [
'William',
'Martyn'
],
'id' => [
'j8zwyk',
'1'
]
]
我需要将其转换为以下格式:
[
0 => [
'email' => "william.pool@gmail.com",
'lastName' => 'Pool',
'firstName' => 'William',
'id' => 'j8zwyk'
],
1 => [
'email' => "martynleeball@gmail.com",
'lastName' => 'Ball',
'firstName' => 'Martyn',
'id' => '1'
]
]
不太确定是什么原因导致此错误，因为npm install在其他计算机上工作正常。
