magento2后台修改eav属性对应的模板

发表于 2018-04-18 更新于 2022-04-15 分类于 magento2

简介

很多情况下我们需要修改后台eav属性对应的模板文件。以下是通过修改模板文件让客户无法在后台修改multiple select，也就是disable multiple select。

代码

<!--
Silk/AdvancedEstimatedShippingDate/etc/adminhtml/di.xml 
-->
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

                </item>
            </argument>
        </arguments>

接下来修改modifyMeta

//Silk\AdvancedEstimatedShippingDate\Ui\DataProvider\Product\Form\Modifier\esd
<?php

namespace Silk\AdvancedEstimatedShippingDate\Ui\DataProvider\Product\Form\Modifier;
use Magento\Framework\Stdlib\ArrayManager;

class esd implements \Magento\Ui\DataProvider\Modifier\ModifierInterface

    /**

    const CONTAINER_PREFIX = 'container_';
    /**

    public function __construct(ArrayManager $arrayManager)
    {
        $this->arrayManager = $arrayManager;
    }

    /**

    public function modifyData(array $data)
    {
        return $data;
    }

    /**

    public function modifyMeta(array $meta)
    {
        $fieldCode = 'esd';
        $elementPath = $this->arrayManager->findPath($fieldCode, $meta, null, 'children');
        $containerPath = $this->arrayManager->findPath(static::CONTAINER_PREFIX . $fieldCode, $meta, null, 'children');
        if (!$elementPath) {
            return $meta;
        }

        $meta = $this->arrayManager->merge(
            $containerPath,
            $meta,
            [
                'arguments' => [
                    'data' => [

                            'label' => __('ESD'),
                            'required' => 0,
                            'sortOrder' => 320,
                            'scopeLabel' => __('[STORE VIEW]'),
                        ],

                                ],
                            ],
                        ],

                ]
            ]
        );
        return $meta;
    }
}

最后加上template文件

在Ubuntu下如何获取超级用户权限

发表于 2015-08-11 更新于 2022-04-15 分类于 Ubuntu

由于 Ubuntu 是基于 Debian 的 linux 操作系统，在默认的情况下，是没有超级用户（superuser， root）的，但有些系统操作必须有超级用户的权限才能进行，如手动释放内存等。在其他 linux 操作系统（如 fedora）下，可以使用 su 切换到超级用户。当输入 su 命令后，系统会要求输入 root 的密码。可是，在 Ubuntu 下我们根本不知道 root 的密码是什么。这样，在 Ubuntu 下切换到超级用户需要使用其他方法，主要有两种： 1） sudo -i sudo 是 su 的加强版，意思是 do something as the supervisor。不需要密码就可以得到 root 的权限。但是它也有很多限制，比如，在默认的情况下，只能在 5 分钟之内使用 root 权限。 2）如果想一直使用 root 权限，还是要使用 su，还是要得到 root 密码的。用 sudo passwd root 可以设置 root 的密码。之后就可以自由使用 su 命令啦。

探讨PHP函数ip2long转换IP时数值太大产生负数的解决方法

发表于 2015-08-11 更新于 2022-04-15 分类于 PHP

本篇文章是对PHP函数ip2long转换IP时数值太大产生负数的解决方法进行了详细的分析介绍，需要的朋友参考下【造成原因】：Because PHP’s integer type is signed, and many IP addresses will result in negative integers. 【解决办法】：其官方手册中提到，可以“you need to use the “%u” formatter of sprintf() or printf() to get the string representation of the unsigned IP address” 即，printf( ‘%u’,ip2long(‘IP地址’ ) ); 或者将其先转换为二进制然后在转换为十进制，bindec(decbinip2long( ‘IP地址’ ) ) ); 【测试】

$strIp = '182.118.0.0';
echo ip2long($strIp); //此时输出的-1233780736
echo 'br/';
echo bindec( decbin( ip2long( $strIp ) ) ); // 输出3061186560，与MySQL函数输出一致~

【注】： number bindec ( string $binary_string ); //二进制转换为十进制 string decbin ( int $number ); //十进制转换为二进制

xunsearch同义词管理

发表于 2015-08-11 更新于 2022-04-15 分类于 xunsearch

Indexer.php 添加同义词

添加同义词

通过带参数的选项 --add-synonym 来实现，参数值为单条或多条同义词记录，每条记录之间用冒号(:) 分隔原词和同义词，多条记录之间用逗号分割。您可以对同一个“原词”增加多个不同的“同义词”，如果库内已存在完全一致的记录，则指令不起作用也不会报错。用法如下：

# 给 search 增加同义词 find
util/Indexer.php demo –add-synonym search:find

# 再给 search 增加另一个同义词 seek
util/Indexer.php demo –add-synonym search:seek

# 给 “搜索” 增加 “检索” “查找” 两个同义词
util/Indexer.php demo -add-synonym 搜索:检索,搜索:查找

# 给 “Hello world” 增加同义词 “你好”，参数含空格请用引号包围
util/Indexer.php demo –add-synonym “Hello world:你好”

删除同义词

删除同义词作法和添加同义词很相似，只不过采用选项 --del-synonym，同时参数中的同义词可以省略表示删除该“原词”的所有同义词记录。用法如下：

# 删除 search 的全部同义词、同时删除 “搜索” 的同义词 “检索”
util/Indexer.php demo –del-synonym search,搜索:检索

Android中invalidate() 函数详解(结合Android 4.0.4 最新源码)

发表于 2015-08-11 更新于 2022-04-15 分类于 android

invalidate()函数的主要作用是请求View树进行重绘，该函数可以由应用程序调用，或者由系统函数间接调用，例如setEnable(), setSelected(), setVisiblity()都会间接调用到invalidate()来请求View树重绘，更新View树的显示。注：requestLayout()和requestFocus()函数也会引起视图重绘下面我们通过源码来了解invalidate()函数的工作原理，首先我们来看View类中invalidate()的实现过程：

[java] view plain copy

/**
* Invalidate the whole view. If the view is visible,
* {@link #onDraw(android.graphics.Canvas)} will be called at some point in
* the future. This must be called from a UI thread. To call from a non-UI thread,
* call {@link #postInvalidate()}.
*/
public void invalidate() {
invalidate(true);
}

invalidate()函数会转而调用invalidate(true)，继续往下看：

[java] view plain copy

/**
* This is where the invalidate() work actually happens. A full invalidate()
* causes the drawing cache to be invalidated, but this function can be called with
* invalidateCache set to false to skip that invalidation step for cases that do not
* need it (for example, a component that remains at the same dimensions with the same
* content).
*
* @param invalidateCache Whether the drawing cache for this view should be invalidated as
* well. This is usually true for a full invalidate, but may be set to false if the
* View’s contents or dimensions have not changed.
*/
void invalidate(boolean invalidateCache) {
if (ViewDebug.TRACE_HIERARCHY) {
ViewDebug.trace(this, ViewDebug.HierarchyTraceType.INVALIDATE);
}
if (skipInvalidate()) {
return;
}
if ((mPrivateFlags & (DRAWN | HAS_BOUNDS)) == (DRAWN | HAS_BOUNDS) ||
(invalidateCache && (mPrivateFlags & DRAWING_CACHE_VALID) == DRAWING_CACHE_VALID) ||
(mPrivateFlags & INVALIDATED) != INVALIDATED || isOpaque() != mLastIsOpaque) {
mLastIsOpaque = isOpaque();
mPrivateFlags &= ~DRAWN;
mPrivateFlags |= DIRTY;
if (invalidateCache) {
mPrivateFlags |= INVALIDATED;
mPrivateFlags &= ~DRAWING_CACHE_VALID;
}
final AttachInfo ai = mAttachInfo;
final ViewParent p = mParent;
//noinspection PointlessBooleanExpression,ConstantConditions
if (!HardwareRenderer.RENDER_DIRTY_REGIONS) {
if (p != null && ai != null && ai.mHardwareAccelerated) {
// fast-track for GL-enabled applications; just invalidate the whole hierarchy
// with a null dirty rect, which tells the ViewAncestor to redraw everything
p.invalidateChild(this, null);
return;
}
}
if (p != null && ai != null) {
final Rect r = ai.mTmpInvalRect;
r.set(0, 0, mRight - mLeft, mBottom - mTop);
// Don’t call invalidate – we don’t want to internally scroll
// our own bounds
p.invalidateChild(this, r);
}
}
}

下面我们来具体进行分析invalidate(true)函数的执行流程： 1、首先调用skipInvalidate()，该函数主要判断该View是否不需要重绘，如果不许要重绘则直接返回，不需要重绘的条件是该View不可见并且未进行动画 2、接下来的if语句是来进一步判断View是否需要绘制，其中表达式 (mPrivateFlags & (DRAWN | HAS_BOUNDS)) == (DRAWN | HAS_BOUNDS)的意思指的是如果View需要重绘并且其大小不为0，其余几个本人也未完全理解，还望高手指点～～如果需要重绘，则处理相关标志位 3、对于开启硬件加速的应用程序，则调用父视图的invalidateChild函数绘制整个区域，否则只绘制dirty区域（r变量所指的区域），这是一个向上回溯的过程，每一层的父View都将自己的显示区域与传入的刷新Rect做交集。接下来看invalidateChild()的实现过程：

[java] view plain copy

public final void invalidateChild(View child, final Rect dirty) {
if (ViewDebug.TRACE_HIERARCHY) {
ViewDebug.trace(this, ViewDebug.HierarchyTraceType.INVALIDATE_CHILD);
}
ViewParent parent = this;
final AttachInfo attachInfo = mAttachInfo;
if (attachInfo != null) {
// If the child is drawing an animation, we want to copy this flag onto
// ourselves and the parent to make sure the invalidate request goes
// through
final boolean drawAnimation = (child.mPrivateFlags & DRAW_ANIMATION) == DRAW_ANIMATION;
if (dirty == null) {
if (child.mLayerType != LAYER_TYPE_NONE) {
mPrivateFlags |= INVALIDATED;
mPrivateFlags &= ~DRAWING_CACHE_VALID;
child.mLocalDirtyRect.setEmpty();
}
do {
View view = null;
if (parent instanceof View) {
view = (View) parent;
if (view.mLayerType != LAYER_TYPE_NONE) {
view.mLocalDirtyRect.setEmpty();
if (view.getParent() instanceof View) {
final View grandParent = (View) view.getParent();
grandParent.mPrivateFlags |= INVALIDATED;
grandParent.mPrivateFlags &= ~DRAWING_CACHE_VALID;
}
}
if ((view.mPrivateFlags & DIRTY_MASK) != 0) {
// already marked dirty - we’re done
break;
}
}
if (drawAnimation) {
if (view != null) {
view.mPrivateFlags |= DRAW_ANIMATION;
} else if (parent instanceof ViewRootImpl) {
((ViewRootImpl) parent).mIsAnimating = true;
}
}
if (parent instanceof ViewRootImpl) {
((ViewRootImpl) parent).invalidate();
parent = null;
} else if (view != null) {
if ((view.mPrivateFlags & DRAWN) == DRAWN ||
(view.mPrivateFlags & DRAWING_CACHE_VALID) == DRAWING_CACHE_VALID) {
view.mPrivateFlags &= ~DRAWING_CACHE_VALID;
view.mPrivateFlags |= DIRTY;
parent = view.mParent;
} else {
parent = null;
}
}
} while (parent != null);
} else {
// Check whether the child that requests the invalidate is fully opaque
final boolean isOpaque = child.isOpaque() && !drawAnimation &&
child.getAnimation() == null;
// Mark the child as dirty, using the appropriate flag
// Make sure we do not set both flags at the same time
int opaqueFlag = isOpaque ? DIRTY_OPAQUE : DIRTY;
if (child.mLayerType != LAYER_TYPE_NONE) {
mPrivateFlags |= INVALIDATED;
mPrivateFlags &= ~DRAWING_CACHE_VALID;
child.mLocalDirtyRect.union(dirty);
}
final int[] location = attachInfo.mInvalidateChildLocation;
location[CHILD_LEFT_INDEX] = child.mLeft;
location[CHILD_TOP_INDEX] = child.mTop;
Matrix childMatrix = child.getMatrix();
if (!childMatrix.isIdentity()) {
RectF boundingRect = attachInfo.mTmpTransformRect;
boundingRect.set(dirty);
//boundingRect.inset(-0.5f, -0.5f);
childMatrix.mapRect(boundingRect);
dirty.set((int) (boundingRect.left - 0.5f),
(int) (boundingRect.top - 0.5f),
(int) (boundingRect.right + 0.5f),
(int) (boundingRect.bottom + 0.5f));
}
do {
View view = null;
if (parent instanceof View) {
view = (View) parent;
if (view.mLayerType != LAYER_TYPE_NONE &&
view.getParent() instanceof View) {
final View grandParent = (View) view.getParent();
grandParent.mPrivateFlags |= INVALIDATED;
grandParent.mPrivateFlags &= ~DRAWING_CACHE_VALID;
}
}
if (drawAnimation) {
if (view != null) {
view.mPrivateFlags |= DRAW_ANIMATION;
} else if (parent instanceof ViewRootImpl) {
((ViewRootImpl) parent).mIsAnimating = true;
}
}
// If the parent is dirty opaque or not dirty, mark it dirty with the opaque
// flag coming from the child that initiated the invalidate
if (view != null) {
if ((view.mViewFlags & FADING_EDGE_MASK) != 0 &&
view.getSolidColor() == 0) {
opaqueFlag = DIRTY;
}
if ((view.mPrivateFlags & DIRTY_MASK) != DIRTY) {
view.mPrivateFlags = (view.mPrivateFlags & ~DIRTY_MASK) | opaqueFlag;
}
}
parent = parent.invalidateChildInParent(location, dirty);
if (view != null) {
// Account for transform on current parent
Matrix m = view.getMatrix();
if (!m.isIdentity()) {
RectF boundingRect = attachInfo.mTmpTransformRect;
boundingRect.set(dirty);
m.mapRect(boundingRect);
dirty.set((int) boundingRect.left, (int) boundingRect.top,
(int) (boundingRect.right + 0.5f),
(int) (boundingRect.bottom + 0.5f));
}
}
} while (parent != null);
}
}
}

大概流程如下，我们主要关注dirty区域不是null（非硬件加速）的情况： 1、判断子视图是否是不透明的（不透明的条件是isOpaque()返回true，视图未进行动画以及child.getAnimation() == null），并将判断结果保存到变量isOpaque中，如果不透明则将变量opaqueFlag设置为DIRTY_OPAQUE，否则设置为DIRTY。 2、定义location保存子视图的左上角坐标 3、如果子视图正在动画，那么父视图也要添加动画标志，如果父视图是ViewGroup，那么给mPrivateFlags添加DRAW_ANIMATION标识，如果父视图是ViewRoot，则给其内部变量mIsAnimating赋值为true 4、设置dirty标识，如果子视图是不透明的，则父视图设置为DIRTY_OPAQUE，否则设置为DIRTY 5、调用parent.invalidateChildInparent()，这里的parent有可能是ViewGroup，也有可能是ViewRoot（最后一次while循环），首先来看ViewGroup, ViewGroup中该函数的主要作用是对dirty区域进行计算以上过程的主体是一个do{}while{}循环，不断的将子视图的dirty区域与父视图做运算来确定最终要重绘的dirty区域，最终循环到ViewRoot（ViewRoot的parent为null）为止，并将dirty区域保存到ViewRoot的mDirty变量中

[java] view plain copy

/**
* Don’t call or override this method. It is used for the implementation of
* the view hierarchy.
*
* This implementation returns null if this ViewGroup does not have a parent,
* if this ViewGroup is already fully invalidated or if the dirty rectangle
* does not intersect with this ViewGroup’s bounds.
*/
public ViewParent invalidateChildInParent(final int[] location, final Rect dirty) {
if (ViewDebug.TRACE_HIERARCHY) {
ViewDebug.trace(this, ViewDebug.HierarchyTraceType.INVALIDATE_CHILD_IN_PARENT);
}
if ((mPrivateFlags & DRAWN) == DRAWN ||
(mPrivateFlags & DRAWING_CACHE_VALID) == DRAWING_CACHE_VALID) {
if ((mGroupFlags & (FLAG_OPTIMIZE_INVALIDATE | FLAG_ANIMATION_DONE)) !=
FLAG_OPTIMIZE_INVALIDATE) {
dirty.offset(location[CHILD_LEFT_INDEX] - mScrollX,
location[CHILD_TOP_INDEX] - mScrollY);
final int left = mLeft;
final int top = mTop;
if ((mGroupFlags & FLAG_CLIP_CHILDREN) != FLAG_CLIP_CHILDREN ||
dirty.intersect(0, 0, mRight - left, mBottom - top) ||
(mPrivateFlags & DRAW_ANIMATION) == DRAW_ANIMATION) {
mPrivateFlags &= ~DRAWING_CACHE_VALID;
location[CHILD_LEFT_INDEX] = left;
location[CHILD_TOP_INDEX] = top;
if (mLayerType != LAYER_TYPE_NONE) {
mLocalDirtyRect.union(dirty);
}
return mParent;
}
} else {
mPrivateFlags &= ~DRAWN & ~DRAWING_CACHE_VALID;
location[CHILD_LEFT_INDEX] = mLeft;
location[CHILD_TOP_INDEX] = mTop;
if ((mGroupFlags & FLAG_CLIP_CHILDREN) == FLAG_CLIP_CHILDREN) {
dirty.set(0, 0, mRight - mLeft, mBottom - mTop);
} else {
// in case the dirty rect extends outside the bounds of this container
dirty.union(0, 0, mRight - mLeft, mBottom - mTop);
}
if (mLayerType != LAYER_TYPE_NONE) {
mLocalDirtyRect.union(dirty);
}
return mParent;
}
}
return null;
}

该函数首先调用offset将子视图的坐标位置转换为在父视图（当前视图）的显示位置，这里主要考虑scroll后导致子视图在父视图中的显示区域会发生变化，接着调用union函数求得当前视图与子视图的交集,求得的交集必定是小于dirty的范围，因为子视图的dirty区域有可能超出其父视图（当前视图）的范围，最后返回当前视图的父视图。再来看ViewRoot中invalidateChildInparent的执行过程：

[java] view plain copy

public ViewParent invalidateChildInParent(final int[] location, final Rect dirty) {
invalidateChild(null, dirty);
return null;
}

该函数仅仅调用了ViewRoot的invalidateChild，下面继续看invalidateChild的源码：

[java] view plain copy

public void invalidateChild(View child, Rect dirty) {
checkThread();
if (DEBUG_DRAW) Log.v(TAG, “Invalidate child: “ + dirty);
if (dirty == null) {
// Fast invalidation for GL-enabled applications; GL must redraw everything
invalidate();
return;
}
if (mCurScrollY != 0 || mTranslator != null) {
mTempRect.set(dirty);
dirty = mTempRect;
if (mCurScrollY != 0) {
dirty.offset(0, -mCurScrollY);
}
if (mTranslator != null) {
mTranslator.translateRectInAppWindowToScreen(dirty);
}
if (mAttachInfo.mScalingRequired) {
dirty.inset(-1, -1);
}
}
if (!mDirty.isEmpty() && !mDirty.contains(dirty)) {
mAttachInfo.mSetIgnoreDirtyState = true;
mAttachInfo.mIgnoreDirtyState = true;
}
mDirty.union(dirty);
if (!mWillDrawSoon) {
scheduleTraversals();
}
}

具体分析如下： 1、判断此次调用是否在UI线程中进行 2、将dirty的坐标位置转换为ViewRoot的屏幕显示区域 3、更新mDirty变量，并调用scheduleTraversals发起重绘请求至此一次invalidate()就结束了总结：invalidate主要给需要重绘的视图添加DIRTY标记，并通过和父视图的矩形运算求得真正需要绘制的区域，并保存在ViewRoot中的mDirty变量中，最后调用scheduleTraversals发起重绘请求，scheduleTraversals会发送一个异步消息，最终调用performTraversals()执行重绘，performTraversals()的具体过程以后再分析。以上所有代码基于Android 4.0.4，并结合《Android内核剖析》分析总结而成，源码中涉及到的部分细节本人也未完全理解，还望高手指点~~
