To pass this challenge, create an Apex class that returns both contacts and leads that have first or last name matching the incoming parameter. The Apex class must have a public static method called 'searchContactsAndLeads'. Because SOSL indexes data for searching, you must create a Contact record and Lead record before checking this challenge.
Both records must have the last name 'Smith'. The challenge uses these records for the SOSL search. I have issues while doing steps in Trailhead. Best Answer chosen by Santi Ram Rai. Mayank Srivastava Just like you created the Contact recordyou need to create a Lead record.
Try the above and let us know if it doesn't work. Also, for trailhead challenges and for any code actuallyI would recommend spending a lot of time to debug your code before you ask for solutions. It will make you a better programmer in the long run.
Just my 2 cents. Please add these records for this challenge. Mayank Srivastava All right, the problem is that you have not created the records for you to complete this challenge.
Before you check the challenge, create a lead record and a contact record each with the last names of 'Smith' and then check the challenge. Santi Ram Rai Yes, i have alrady created. Mayank Srivastava Ok so that's just the Contact record.
Did you create a Lead record with the last name as Smith as well? Santi Ram Rai Ho to create a Lead record? Because i am just following the steps. But can u explain me what is the differences between "Contact record" and " Lead record "?
It only takes a minute to sign up. May be it's not documented anywhere Or google doesn't know where it is. The act of creation of object shouldn't have immediate dangerous side effects. If I'll create hundreds of your objects - will they all fire 1 DML?
User should understand what he's doing "are you sure you want to delete these records?
Create an Apex class that returns both contacts and leads based on a parameter.
Establishing connection to DB - OK. Constructor is used to create an object and initialize it's parameters; nothing more. I was trying to search for a better explanation but I failed.Active sky xp11
It was enterprise project. The company had a lot of documents regarding how to code. I think Select was ok.G502 double click fix
But I doubt it. Second, it may fail and object just doesn't create at all. In this case memory is allocated but object isn't created there.

Scenario: I have a custom button on a standard layout, which will call an apex class to do some validation on a record.
If not validated, it needs to throw out some errors on that page. What are the best UX options to achieve this? I am not too sure how to achieve this. Within a trigger, you can use the addError method to add the custom errors. Can my Apex class reference the fields of a standard object? The ideal approach would be to do the following:. What I have thought: Having a VF Page popup on the screen so that user can see all the errors, but that's not the best approach as UX is a big deal for this application.
The short answer is that you need an outputPanel VF component in your page that renders if you have a message to show. I think your best bet is to just include the detail of the record page on the VF "error page" so adding the apex:detail component just below your error text would make the page look just like the standard object layout but it would in fact be a VF page with your validation logic and error surfacing.
It's probably not as slick as what you're after, but it seems like the best route might be for the button to open a blank VF page, which does the processing from an Init method in the controller. If there's no error processing then you could simply redirect them at the end of the method call to the original record again.
Your apex class has to populate the field with the error and the field to receive the error. Then create a trigger that runs before update that checks if that field s is filled. If it is, it throws an error using the text on that field. You can use the addError method to add the error message to be displayed on the standard UI in your trigger. An example code will look like this:. If you want to perform validations on more than one field and display all validation error messages, keep adding the validations and return just once after your validation is complete by tracking through a variable flag.
Edit: The above works only in trigger. Couple of options to display error messages on the click of the custom button in standard page are: a.Once I began using Apex, I started understanding the lessons, passing tests.

The TestDataFactory class is a special type of class—it is a public class that is annotated with isTest and can be accessed only from a running test.
Test utility classes contain methods that can be called by test methods to perform useful tasks, such as setting up test data. This test utility class contains one static method, createAccountsWithOppswhich accepts the number of accounts held in the numAccts parameter and the number of related opportunities to create for each account held in the numOppsPerAcct parameter. The first loop in the method creates the specified number of accounts and stores them in the accts list variable.
After the first loop, the insert DML statement is called to create all accounts in the list in the database. The second loop creates the opportunities. Because each group of opportunities are linked to one account, the outer loop iterates through accounts and contains a nested loop that creates related opportunities for the current account. The next time the nested loop is run, opportunities are added to the same list using the add method. Opportunities are linked to their parent accounts using the AccountId field.
Next, the insert DML statement is efficiently called outside the loop to create all opportunities in the collection for all accounts in one call only. The array returned by the TestDataFactory. One test method is not enough to test all the possible inputs for the trigger. We need to test some other conditions, such as when an account without opportunities is deleted. We also need to test the same scenarios with a bulk number of records instead of just a single record. Here is an updated version of the test class that contains the three additional test methods.
Save this updated version of the class.
Create a contact test factory – Apex Testing
The final step is to run the test methods in our test class, now that the class contains more comprehensive tests and has been refactored to use a test data factory. Learning Objectives After completing this unit, you'll be able to: Create a test utility class. Use a test utility method to set up test data for various test cases. Execute all test methods in a class. Create Test Data for Apex Tests Use test utility classes to add reusable methods for test data setup. Replace the default class body with the following.
Testing for Different Conditions One test method is not enough to test all the possible inputs for the trigger. Running All Test Methods The final step is to run the test methods in our test class, now that the class contains more comprehensive tests and has been refactored to use a test data factory. To execute the same test run, click the Tests tab, select your test run, and then click Test Rerun.

Create or Update Custom Metadata Type via Apex code – Salesforce Summer 17
The test run should report that all four tests passed!I am new to Saleforce development. Please can any one guide me to sample apex code to create add custom fields to custom or standard objects dynamically using Salesforce Metadata API in my development org.
Its a web service API used by external clients.
Unfortunately the answer is no to both of these. I can't find much in the way of ideas regarding this either. This seems to be a way to access external web services. You can't callout to any Salesforce web services from within Salesforce. You can only callout to external web services.
Not using API's, Can we create fields for the objects using apex programming dynamically. Any one had know about it please provide the code or suggestions to create fields. You can try the following. Consume the Metadata api in apex. This will require a bit of tweaking in the Metadata api wsdl. Modify the generate apex code so that it could be saved. You might need to rename the update and delete method of the generated class to something else.Joseph walsh (jwalsh)
Once you have done that with few minor modification in the generated class you can use it to create fields and custom object programatically. CustomObject ; customObject. CustomField ; customObject. Is there some kind of update step missing from the code you posted, as there might be in a trigger, for example?
Any help greatly appreciated. The Metadata API from Salesforce is asyncronous, notice the return result from the 'create' operation. The deploy and retrieve samples utilise apex:actionPoller.
My hunch is that it is failing and you need to utilise one of the above approaches to find out why. If your in a Visualforce context its best to store the return AsyncResult in your controller then allow the page to rerender with an actionPoller on it, which will check the request for completion. Once done you can retrieve any error messages.
Though it is doing a 'deploy' operation and not a 'create' operation, this example can be adapted to show the results of a 'create' operation. The page then uses this to call it periodically. Or if your just trying things out, you could execute the code via Anonymous Apex and output the AsyncResult ID to the debug log. If in the meantime you want to share the code your running I can try to spot an obvious issues or problems.Where to buy small hinges
I'm trying to create custom fields based upon the names of some of my SFDC objects, triggered by user actions. My trigger, and the extra method I added to your MetadataService are below:. Your still not checking the AsyncResult status, you need to do this via calling MetadataService. To do this you need to use actionPoller in Visualforce context or via Batch Apex job future is not suitable as you cannot creating a polling condition in this context in other contexts, such as Apex Trigger in your case.
As I can see your working in a Apex Trigger context, I assume you don't have a Visualforce page or prefer not to create one for the user action being performed?Like other object-oriented programming languages, these are some of the language constructs that Apex supports:. You can write Apex and access debugging information directly in the browser by using the Salesforce user interface.
Open the Developer Console under Your Name or the quick access menu. Lists hold an ordered collection of objects. Lists in Apex are synonymous with arrays and the two can be used interchangeably. The following two declarations are equivalent.
The colors variable is declared using the List syntax.
Alternatively, the colors variable can be declared as an array but assigned to a list rather than an array. You can add elements to a list when creating the list, or after creating the list by calling the add method. This first example shows you both ways of adding elements to a list. List elements can be read by specifying an index between square brackets, just like with array elements.
Also, you can use the get method to read a list element. This example is based on the lists created in the previous example and shows how to read list elements using either method.
The example also shows how to iterate over array elements. Apex supports two other collection types: Set and Map. You can learn more about these in the Collections section of the Apex Developer Guide. The EmailManager class has a public method sendMail that sends email and uses built-in Messaging methods of the Apex class library.
This helper method inspects the results of the email send call and is called by sendMail. The class you just saved makes use of object-oriented programming OOP. The class encapsulates the methods that are related to managing email.
Anonymous Apex allows you to run lines of code on the fly and is a handy way to invoke Apex, especially to test out functionality. Debug log results are generated, as with any other Apex execution.
There are other ways to invoke Apex, for example, through triggers. Now that this method has executed, you should have received an email in your inbox. Check your email! Debug logs are useful for debugging your code.
When Apex methods execute, the calls are logged in the debug log. Also, you can write your own debug messages to the log, which helps in debugging your code in case there are errors. The inspectResults helper method, which is called by sendMailwrites messages to the log by using the System. You can look for these messages in the debug log that was generated when you executed the method. Also, you can filter the debug log by searching for any keyword in the Filter field, or by selecting any of the other options.
For more information, see the Log Inspector help. Now that this method has executed, you can check your email, and optionally, the debug log as in the previous steps.
Learning Objectives After completing this unit, you'll be able to: Describe the key features of the Apex programming language. Save an Apex class and call methods with Anonymous. Use the Developer Console to inspect debug logs.
Get Started with Apex Apex is a programming language that uses Java-like syntax and acts like database stored procedures. Apex enables developers to add business logic to system events, such as button clicks, updates of related records, and Visualforce pages. Apex Language Highlights Like other object-oriented programming languages, these are some of the language constructs that Apex supports: Classes, interfaces, properties, and collections including arrays.
