I want to create lookup relationship between two custom object project and todo object but not able to do so
This is the code to create lookup relationship between two object. It contain class two methods for create project and the create task respectively
public class ProjectAssignment { *//class ProjectAssignment*
public static void createProject(){ *//method to create an object*
Project__c pr=new Project__c();
pr.Name='IseeIt'; //name of project
pr.Start_Date__c= date.today()`
pr.Description__c='This Is To Do Kind Project';
pr.End_Date__c=date.today()+5;
insert pr;
}
public static void createTask(){ *//create todo method
//Code to fetch data*
Project__c pr = [Select Id from Project__c]; *//query for lookup relationship between project and todo*
ToDo__c td = new ToDo__c();
td.Project__c= pr.Id; *//fetchhing project id*
td.Start_Date__c=date.today();
td.Description__c='This is the first task';
td.End_Date__c=date.today()+2;
insert td;
}
}
"System.QueryException: List has more than 1 row for assignment to SObject"
because their are two project i have created in the project object
Try this.
Project__c pr = [Select Id from Project__c];
For this, you have to Select the query in where clause and put LIMIt 1 so that they give you only one record.
Project__c pr = [Select Id from Project__c where name = 'IseeIt' LIMIT 1];

I am trying to understand this code ,this seems to be a test class,but i am having hard time to understand the code,i know conceptually how List and Map collection works in Sales force,but this seems to be little difficult to understand,
.In brief to me this seems to test a method which browses a list of CollaborationGroupMember.
For that, CollaborationGroup has been created and code tried to add one User.
can some one please take some time to make me understand the below code line by line?
Thanks in advance
#isTest
public class TestGroupFactory {
public static Map<CollaborationGroup, List<CollaborationGroupMember>> groupWithMember() {
CollaborationGroup groupe = new CollaborationGroup(Name = 'Test1', CollaborationType = 'Public');
insert groupe;
groupe = [SELECT Id, Name FROM CollaborationGroup WHERE Name = 'Test1'];
List<User> users = [SELECT Id, Name, Numero_de_plaque__c, SenderEmail
FROM User
WHERE Name = 'User User'];
List<CollaborationGroupMember> cgms = new List<CollaborationGroupMember>();
for (User u : users) {
CollaborationGroupMember cgm = new CollaborationGroupMember();
cgm.CollaborationGroupId = groupe.Id;
cgm.MemberId = u.Id;
cgms.add(cgm);
}
insert cgms;
return new Map<CollaborationGroup, List<CollaborationGroupMember>>{groupe => cgms};
}
}
It is technically a test class, but it does not perform any tests. Its purpose is to create test data for other test classes that contain test methods. The reason it has the #isTest annotation is so that it is only accessible in test context and does not count against the total test coverage of the organization.
The method shown creates a Chatter Group and adds Users to the group if they have the name "User User".
The code below inserts the Chatter Group and then retrieves it so the Id is available. I don't think the retrieval is necessary in this instance, but I'd have to test it.
CollaborationGroup groupe = new CollaborationGroup(Name = 'Test1', CollaborationType = 'Public');
insert groupe;
groupe = [SELECT Id, Name FROM CollaborationGroup WHERE Name = 'Test1'];
The next section retrieves the Users (presumably created in another test class)
List<User> users = [SELECT Id, Name, Numero_de_plaque__c, SenderEmail
FROM User
WHERE Name = 'User User'];
Then, a list of CollaborationGroupMembers is instantiated. A loop begins that iterates over every User. For each user, a new CollaborationGroupMember is instantiated and added to the list.
List<CollaborationGroupMember> cgms = new List<CollaborationGroupMember>();
for (User u : users) {
CollaborationGroupMember cgm = new CollaborationGroupMember();
cgm.CollaborationGroupId = groupe.Id;
cgm.MemberId = u.Id;
cgms.add(cgm);
}
The group members are inserted
insert cgms;
The group and group members are added to a map and returned
return new Map<CollaborationGroup, List<CollaborationGroupMember>>{groupe => cgms};
I've got the problem with searching database through duplicate list values.
First I search all occurrences by given string.
var parentIdList = await _context.ECATEGORIES
.Where(a => a.NAME.ToLower().Contains(partOfName.ToLower()))
.ToListAsync(ct);
then
I retrieve all names when given PARENTID of parentIdList equals database ID
var mainName = await _context.ECATEGORIES
.Where(a=> parentIdList.Any(p=>p.PARENTID==a.ID) )
.Select(s => s.NAME)
.ToListAsync(ct);
My problem is that, sometimes property PARENTID is duplicated.
For example PARENTID = {1,1,2,2,4,5,6}
then result is mainName = {"a","b","c","d","e"}
But I want mainName = {"a", "a","b","b","c","d","e"}
So you have a sequence of Categories, where every Category has an Id, a ParentId and a Name. You also have a string partOfName
You want the Names of Categories. All Categories? No. only those Categories that have a Parent which has a Name that looks like partOfName (looks like is represented by the use of the function contains in your code)
I'm not sure if you use entity framework. Your use of _context seems a hint to this. In that case, It would be easier to use the virtual parent properties. See later.
If you do not use entity framework, I'd advise to fetch your data in one query: join the elements with their parents, and keep only the join results where the parent meets your contains predicate:
string lowerCasePartOfName = partOfName.ToLower(); // for efficiency: do this only once
IQueryable<Category> categories = myDbContext.Categories;
IQueryable<Category> validParents = myDbContext.Categories
.Where(category => category.Name.ToLower().Contains(lowerCasePartOfName))
Now join every Category with the validParentIds on Category.ParentId = Parent.Id
var query = Categories.Join(validParents, // join categories with validParents
category => category.ParentId, // from each category take the ParentId
parent => parent.Id, // from each valid parent take the Id
(category, parent) => new // when they match make one new object
{
CategoryName = category.Name,
});
Note, until now the query has been made, it has not been executed yet. If you want you can concatenate them into one big LINQ query. I'm not sure if that would increase performance very much; however, it would decrease readability.
var result = query.ToListAsync();
Entity Framework Solution
If you use entity framework, your Category class would be like:
class Category
{
public int Id {get; set;}
public string Name {get; set;}
// every Category has zero or one Parent category:
public int? ParentId {get; set;}
public Category Parent {get; set;}
// every Category has zero or more Children, each of them has this Category as Parent
public virtual ICollection<Category> Children {get; set;}
}
You query will be much simpler:
Give me all names of Categories whose Parents have a name that looks like partOfName
string lowerCasePartOfName = partOfName.ToLower();
var result = myDbContext.Categories
// keep only the Categories whose name looks like:
.Where(category => category.Parent.Name.ToLower().Contains(lowerCasePartOfName))
.Select(category => category.Name);
Please Help!!!
I have this Apex controller class that I'm trying to deploy from Salesforce Sandbox to Production but I'm not getting the code coverage required!!
the class is consuming 3 objects, one is stranded and 2 are custom and constructing a hierarchy tree view for those three objects.
//Apex Class
public class TeeView {
/* Wrapper class to contain the nodes and their children */
public class cNodes
{
Public StandardObject gparent {get;set;}
public List<CustomObject1__c> parent {get; set;}
Public List<CustomObject2__c> child {get;set;}
public cNodes(StandardObject gp, List<CustomObject1__c> p, List<CustomObject2__c> c)
{
parent = p;
gparent = gp;
child = c;
}
}
/* end of Wrapper class */
Public List<cNodes> hierarchy;
Public List<cNodes> getmainnodes()
{
hierarchy = new List<cNodes>();
List<StandardObject> tempparent = [Select Id,Name , End_Date__c, Owner.Name Account.Name from Contract ];
for (Integer i =0; i< tempparent.size() ; i++)
{
List<CustomObject1__c> tempchildren = [Select Id,Name, Owner.Name , (select Id,Name, Owner.Name from CustomObject2__r) from CustomObject1__c where Related_Field__c = :tempparent[i].Id];
List<CustomObject2__c> tempchild = [Select Id,Name Owner.Name from CustomObject2__c where Related_Field__c= :tempparent[i].Id];
hierarchy.add(new cNodes(tempparent[i],tempchildren, tempchild));
}
return hierarchy;
}
}
//Test Class
#isTest
public class treeviewTest
{
static testMethod void test1()
{
test.startTest();
Account acc = new Account(Name = 'Unit test account');
insert acc;
StandardObject c = new StandardObject(
Name = 'test',
AccountId = acc.Id,
Status = 'Draft',
StartDate = System.today());
try
{
insert c;
}
catch (Exception ex)
{
ApexPages.addMessages(ex);
}
List<StandardObject> standard = [select Id, Name from StandardObject where Name = 'test'];
system.assertequals(standard.size(), 1);
CustomObject1__c s = new CustomObject1__c(
Related_StandardObjectField__c = c.Id,
Name = 'test'
);
try
{
insert s;
}
catch (Exception ex)
{
ApexPages.addMessages(ex);
}
List<CustomObject1__c> cus1 = [select Id, Name from CustomObject1__c where Name = 'test'];
system.assertequals(cus1.size(), 1);
insert new CustomObject2__c(Related_StandardObjectField__c = c.Id, Description__c = 'test');
List<CustomObject2__c> cus2 = [select Id, Name from CustomObject2__c where Description__c = 'test'];
system.assertequals(cus2.size(), 1);
insert new CustomObject2__c(Related_CustomObject1Field__c = s.Id, Description__c = 'test');
List<Mods__c> cus3 = [select Id, Name from Mods__c where Description__c = 'test'];
system.assertequals(cus3.size(), 1);
treeView view = new treeView();
view.getmainnodes();
test.stopTest();
}
}
Oh man, where do we even start... Looks like you copy-pasted some code at random trying to get the test to work? Your code works on Contract, CustomObject1__c, CustomObject2__c. Your unit test inserts Contract, Subaward__c, Mods__c. Was this some attempt at anonymizing your code? And what's this List<StandardObject> thing, it shouldn't even compile.
I think you need help of a developer with more experience, you've cobbled something together but it doesn't follow the Salesforce best practices for code...
About the main class
Smart use of subqueries will mean
you waste less SOQL (it's bad idea to blindly select all records without any filters but whatever),
don't run into errors related to "too many SOQL statements" (the limit is 100 so since you query in a loop - your code will crash and burn the moment you have around 50 Contracts)
lead to compact code occupying less lines (easier to maintain & cover with tests).
I'd go with something like that, query Contract & first related list in one go and then the parents + children in another query. Using a Map to link them for displaying.
List<Contract> levelOneAndTwo = [SELECT Id, Name, End_Date__c, Owner.Name, Account.Name,
(SELECT Id,Name, Owner.Name FROM Subawards__r)
FROM Contract];
Map<Id, SubAward__c> levelTwoAndThree = new Map<Id, Subaward__c>([SELECT Id,
(SELECT Id,Name Owner.Name FROM Mods__r)
FROM Subaward__c WHERE Contract__c = :levelOneAndTwo];
);
This wastes only 2 queries but fetches all contracts and their related data. Then you can loop over results building your wrapper object or just feed it directly to Visualforce for displaying.
About the unit test
You don't get the coverage because you're spread too thin. One unit test methods inserts only Contracts (so your main query will hit something, give you some coverage). Then another method (in completely different context) inserts some child objects - but they don't matter. In that other method there are 0 contracts so it won't even enter your main loop. Combine it into one?
Account acc = new Account(Name = 'Unit test account');
insert acc;
Contract c = new Contract(
Name = 'test contract',
AccountId = acc.Id,
Status = 'Draft',
StartDate = System.today()
);
insert c;
Subaward__c s = new Subaward(
Contract__c = c.Id,
Name = 'test'
);
insert s;
insert new Mod__c(Subaward__c = c.Id, Description__c = 'test');
Now you have nice tree hierarchy set up, from Account all the way down. Queries in the test should hit some data.
I was finally able to get %100 code coverage for the above class by adding these lines to the test class:
treeView view = new treeView();
view.getmainnodes();
system.assert(view.hierarchy.size() > 0);
So my end goal for this project is to create a contact and a case for each customer that registers a product on my companies warranty registration page.
I have already got a python script that connects to a MySQL database and saves the needed info into an .xlsx file and then another python script currently sending that same data from the .xlsx file into salesforce and it works for a Case OR a Contact but not both. Apex trigger only works if I actually do a web-to-case or email-to-case but for some reason does not work with python.
This will be something that will be triggered roughly every 6 hours indefinitely. I already got it setup to where it does not pull the same data twice from the database so it only grabs new contacts from the MySQL database by writing a '1' to a new column in each table and does a check if '1' exists and if it does then skip it. Everything is working EXCEPT for creating a Contact AND a Case. Contact specifically because it will have all the address information we need for when a customer calls in for troubleshooting of their product, we want a case also created because that is where the product and serial numbers are taken down and allows a trigger to send the customer an email once the case has been created.
public class CaseAutocreateContactTest {
public static testMethod void testBulkContactsGetCreated() {
List<Case> newCases = new List<Case>();
for (Integer i = 0; i<100; i++) {
Case c = new Case(SuppliedEmail='jdoe_test_test#doe.com' + i,
SuppliedName='John Doe' + i,
Subject='Feedback - Something' + i);
newCases.add(c);
}
insert newCases;
System.debug('here');
List<Id> newCaseIds = new List<Id>();
for (Case caseObj:newCases) {
newCaseIds.add(caseObj.Id);
}
List<Case> updatedCases = [Select ContactId From Case Where Id in :newCaseIds];
for (Case caseObj:updatedCases) {
System.debug(caseObj.Id + ' ' + caseObj.ContactId);
System.assert(caseObj.ContactId!=null,'There should be no null contacts');
}
}
public static testMethod void testContactGetsCreated() {
Case c = new Case(SuppliedEmail='jdoe_test_test#doe.com',
SuppliedName='John Doe',
Subject='Feedback - Something');
insert c;
List<Contact> johnDoes = [select Id from Contact where Email='jdoe_test_test#doe.com'];
//there should be only 1 -- the trigger should not have created another
System.assert(johnDoes.size()==1, 'There should be one John Doe!');
Case caseObj = [select ContactId from Case where Id=:c.Id];
System.assert(caseObj.ContactId!=null,'There should be no null contact on the case');
}
public static testMethod void testNoDupesAreCreated() {
Contact cnt1 = new Contact(FirstName = 'John',
LastName = 'Doe',
Email='jdoe_test_test#doe.com');
insert cnt1;
Case case1 = new Case(SuppliedEmail='jdoe_test_test#doe.com',
SuppliedName='John Doe',
Subject='Feedback - Something');
insert case1;
List<Contact> johnDoes = [select Id from Contact where Email='jdoe_test_test#doe.com'];
//there should be only 1 -- the trigger should not have created another
System.assert(johnDoes.size()==1, 'There should be only one John Doe!');
}
public static testMethod void testEmailNameDoesntGetCreated() {
Case c = new Case(SuppliedEmail='testEmailNameDoesntGetCreated#doe.com',
SuppliedName='testEmailNameDoesntGetCreated#doe.com',
Subject='Feedback - Something');
insert c;
List<Contact> johnDoes = [select Id from Contact where Email='testEmailNameDoesntGetCreated#doe.com'];
//there should be only 1 -- the trigger should not have created another
System.assert(johnDoes.size()==0, 'There should be no John Does!');
}
}
I got it to work.
So I first created a Contact like I already had working with Simple-Salesforce and then used Selenium package in Python to open web-to-case html file hosted locally and send the data from the .xlsx sheet and submit. Confirmed it creates a case for each customer in .xlsx sheet and confirmed salesforce associates the contact and case with one another.
I am pretty new to SFDC. I am trying to implement a clone functionality of a custom object by which when I am cloning an object, the object as well as all the object in its related list are to be cloned. I have implemented the part of cloning a object but stuck how to get the object list associated with a object's related list. pls let me know , how to implement this.
Thanks
You can try this...
public class PurchaseOrderCloneWithItemsController {
//added an instance varaible for the standard controller
private ApexPages.StandardController controller {get; set;}
// add the instance for the variables being passed by id on the url
private Purchase_Order__c po {get;set;}
// set the id of the record that is created -- ONLY USED BY THE TEST CLASS
public ID newRecordId {get;set;}
// initialize the controller
public PurchaseOrderCloneWithItemsController(ApexPages.StandardController controller) {
//initialize the stanrdard controller
this.controller = controller;
// load the current record
po = (Purchase_Order__c)controller.getRecord();
}
// method called from the VF's action attribute to clone the po
public PageReference cloneWithItems() {
// setup the save point for rollback
Savepoint sp = Database.setSavepoint();
Purchase_Order__c newPO;
try {
//copy the purchase order - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
po = [select Id, Name, Ship_To__c, PO_Number__c, Supplier__c, Supplier_Contact__c, Date_Needed__c, Status__c, Type_of_Purchase__c, Terms__c, Shipping__c, Discount__c from Purchase_Order__c where id = :po.id];
newPO = po.clone(false);
insert newPO;
// set the id of the new po created for testing
newRecordId = newPO.id;
// copy over the line items - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
List<Purchased_Item__c> items = new List<Purchased_Item__c>();
for (Purchased_Item__c pi : [Select p.Id, p.Unit_Price__c, p.Quantity__c, p.Memo__c, p.Description__c From Purchased_Item__c p where Purchase_Order__c = :po.id]) {
Purchased_Item__c newPI = pi.clone(false);
newPI.Purchase_Order__c = newPO.id;
items.add(newPI);
}
insert items;
} catch (Exception e){
// roll everything back in case of error
Database.rollback(sp);
ApexPages.addMessages(e);
return null;
}
return new PageReference('/'+newPO.id+'/e?retURL=%2F'+newPO.id);
}
