[Salesforce]Lightning Design System

Lightning Design Systemを使ってVisualforceでLightning雰囲気のページ作成するのを共有する。

現在Salesforceの主なページ作成はVisualforceページですが、Salesforceが提供しているCSSフレームワーク Lightning Design System を使ってみる。

開発コンソル画面を開き、Visualforce ページ作成する。

簡単な解説です。

・ Lightning Design SystemのSVGアイコン使用宣言

xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"

・ Lightning Design Systemのスタイル、アセットをVisualforceページにインポート

<apex:slds />

・「Contact」へアクセスし、javascriptで呼び出し

<apex:remoteObjectModel name="Contact" fields="Id,Name,Title,LastModifiedDate,PhotoUrl"/>

・ Lightning Design Systemの適用範囲

<div class="slds-scope">...</div>

[Salesforce] Lightning ExperienceのURL遷移

navigateToURLによるページ画面に遷移する例は以下です。

//Component: LightningNavigate
<aura:component implements="force:appHostable">
    <div id="aura-page">
        <div class="container">
            <ui:button label="gotoURL" press="{!c.gotoURL}" />
        </div>
        <div class="container">
            <ui:button label="navigate" press="{!c.navigate}" />
        </div>
    </div>
</aura:component>

//Controller
({
    gotoURL : function(component, event, helper) {
        helper.gotoURL(component);
    },
    navigate : function(component, event, helper) {
        helper.navigate(component);
    }
})

//Helper
({
    gotoURL : function (component, event) {
        var urlEvent = $A.get("e.force:navigateToURL");
        urlEvent.setParams({
          "url": "/006/o"
        });
        urlEvent.fire();
    },
    navigate : function(component,event) {
        var address = '/Salesforce.com+Inc/@37.793779,-122.39448,17z/';
        var urlEvent = $A.get("e.force:navigateToURL");
        urlEvent.setParams({
          "url": 'https://www.google.com/maps/place/' + address
        });
        urlEvent.fire();
    }
})

//App
<aura:application >
    <c:LightningNavigate />
</aura:application>

[Salesforce]Lightning ExperienceのLightningアクション作成　：　取引先詳細画面で取引先責任者レコード作成する

１．Lightning Component作成

                class="slds-button slds-button--brand" />
        </div>

    </div>

</aura:component>

２．Lightning Controller作成

quickcontactController.js

({
    doInit : function(component, event, helper) {

        // Prepare the action to load account record
        var action = component.get("c.getAccount");
        action.setParams({"accountId": component.get("v.recordId")});

        // Configure response handler
        action.setCallback(this, function(response) {
            var state = response.getState();
            if(component.isValid() && state === "SUCCESS") {
                component.set("v.account", response.getReturnValue());
            } else {
                console.log('Problem getting account, response state: ' + state);
            }
        });
        $A.enqueueAction(action);
    },

    handleSaveContact: function(component, event, helper) {
        if(helper.validateContactForm(component)) {
            component.set("v.hasErrors", false);

            // Prepare the action to create the new contact
            var saveContactAction = component.get("c.saveContactWithAccount");
            saveContactAction.setParams({
                "contact": component.get("v.newContact"),
                "accountId": component.get("v.recordId")
            });

            // Configure the response handler for the action
            saveContactAction.setCallback(this, function(response) {
                var state = response.getState();
                if(component.isValid() && state === "SUCCESS") {

                    // Prepare a toast UI message
                    var resultsToast = $A.get("e.force:showToast");
                    resultsToast.setParams({
                        "title": "Contact Saved",
                        "message": "The new contact was created."
                    });

                    // Update the UI: close panel, show toast, refresh account page
                    $A.get("e.force:closeQuickAction").fire();
                    resultsToast.fire();
                    $A.get("e.force:refreshView").fire();
                }
                else if (state === "ERROR") {
                    console.log('Problem saving contact, response state: ' + state);
                }
                else {
                    console.log('Unknown problem, response state: ' + state);
                }
            });

            // Send the request to create the new contact
            $A.enqueueAction(saveContactAction);
        }
        else {
            // New contact form failed validation, show a message to review errors
            component.set("v.hasErrors", true);
        }
    },

	handleCancel: function(component, event, helper) {
	    $A.get("e.force:closeQuickAction").fire();
    }
})

３．Lightning Helper作成

quickcontactHelper.js

({
	validateContactForm: function(component) {
        var validContact = true;

        // First and Last Name are required
        var firstNameField = component.find("contactFirstName");
        if($A.util.isEmpty(firstNameField.get("v.value"))) {
            validContact = false;
            firstNameField.set("v.errors", [{message:"First name can't be blank"}]);
        }
        else {
            firstNameField.set("v.errors", null);
        }
        var lastNameField = component.find("contactLastName");
        if($A.util.isEmpty(lastNameField.get("v.value"))) {
            validContact = false;
            lastNameField.set("v.errors", [{message:"Last name can't be blank"}]);
        }
        else {
            lastNameField.set("v.errors", null);
        }

        // Verify we have an account to attach it to
        var account = component.get("v.account");
        if($A.util.isEmpty(account)) {
            validContact = false;
            console.log("Quick action context doesn't have a valid account.");
        }

        // TODO: (Maybe) Validate email and phone number

        return(validContact);
	}
})

４．取引先でアクション追加

[Salesforce]VisualForce、Apex で現在のユーザ情報取得

SalesforceでVisualForce、Apex で現在のユーザ情報取得方法を共有します。

１． VisualForceで現在のユーザ情報取得方法

<apex:page>
  <h1>Congratulations</h1>
   This is your new Apex Page
   <p>The current company name for this 
      user is: {!$User.CompanyName}</p>
   <p>Is the user active?  
      {!$User.isActive}</p>
</apex:page>

２． Apex で現在のユーザ情報取得方法

String result = UserInfo.getLocale();
System.assertEquals('en_US', result);

[Salesforce]StandardControllerとStandardSetController使い分け

Salesforceでよく使われているStandardControllerとStandardSetController使い分けについて共有する。

１．カスタムボタンでの使い分け

表示ボタン　：　 StandardController

リストビューボタン　：　 StandardSetController

※表示ボタン　：　詳細画面に配置して使用

※リストビューボタン　：　関連リストのメニューに配置して使用

２．Visualforceとコントローラでの使い分け

StandardController の場合

・Visualforce page

<apex:page standardController="Account" extensions="myControllerExtension">
    {!greeting} <p/>
    <apex:form>
        <apex:inputField value="{!account.name}"/> <p/>
        <apex:commandButton value="Save" action="{!save}"/>
    </apex:form>
</apex:page>

・コントローラ

public class myControllerExtension {

    private final Account acct;
    
    // The extension constructor initializes the private member
    // variable acct by using the getRecord method from the standard
    // controller.
    public myControllerExtension(ApexPages.StandardController stdController) {
        this.acct = (Account)stdController.getRecord();
    }

    public String getGreeting() {
        return 'Hello ' + acct.name + ' (' + acct.id + ')';
    }
}

StandardSetController

・Visualforce Page

<apex:page controller="opportunityList2Con">
    <apex:pageBlock>
        <apex:pageBlockTable value="{!opportunities}" var="o">
            <apex:column value="{!o.Name}"/>
            <apex:column value="{!o.CloseDate}"/>
        </apex:pageBlockTable>
    </apex:pageBlock>
</apex:page>

・コントローラ

public class opportunityList2Con {
    // ApexPages.StandardSetController must be instantiated
    // for standard list controllers
    public ApexPages.StandardSetController setCon {
        get {
            if(setCon == null) {
                setCon = new ApexPages.StandardSetController(Database.getQueryLocator(
                    [SELECT Name, CloseDate FROM Opportunity]));
            }
            return setCon;
        }
        set;
    }

    // Initialize setCon and return a list of records
    public List<Opportunity> getOpportunities() {
        return (List<Opportunity>) setCon.getRecords();
    }
}

[Salesforce]ClassicのOnClick JavaScriptボタンのLightning Experience移行

SalesforceのClassicでOnClick JavaScriptボタンをLightning Experienceに移行する際にその方法の一つを共有します。

１．詳細ボタンの場合

Classic：

window.open(“/apex/Test_VF?id=”+ ids, “_blank”);

Lightning Experience：

window.location.href = '/apex/Test_VF?id={!ids}';

２．リストビューボタンの場合

Classic：

var ids = {!GETRECORDIDS($ObjectType.Test__c)};

if (ids.length === 0) {
    alert('None');
} else {
    var test_url = '{!URLFOR("/apex/Test_VF?id=")}' ;
    window.open(test_url + ids, 'Test');
}

Lightning Experience：

<script type="text/javascript">
    var __sfdcSessionId = '{!GETSESSIONID()}';
</script>

<script src="../../soap/ajax/44.0/connection.js" type="text/javascript"></script>

<script src="../../soap/ajax/44.0/apex.js" type="text/javascript"></script>

<script type="text/javascript">
    var ids = "<apex:repeat value="{!selected}" var="obj">{!obj.Id},</apex:repeat>".slice(0,-1).split(',');
    if (ids[0] == "") { 
        alert('None');
        history.back();
    } else { 
        window.location.href = '/apex/Test_VF?id='+ids;
    }
</script>
