Pablo Ledesma 8 Create an Apex REST service that returns an account and it's contacts.
Hi
I have been trying to pass this challenge (https://trailhead.salesforce.com/en/trails/force_com_dev_intermediate/modules/apex_integration_services/units/apex_integration_webservices):
To pass this challenge, create an Apex REST class that is accessible at '/Accounts/<Account_ID>/contacts'. The service will return the account's ID and Name plus the ID and Name of all contacts associated with the account. Write unit tests that achieve 100% code coverage for the class and run your Apex tests.
The Apex class must be called 'AccountManager'.
The Apex class must have a method called 'getAccount' that is annotated with @HttpGet
The method must return the ID and Name for the requested record and all associated contacts with their ID and Name.
The unit tests must be in a separate Apex class called 'AccountManagerTest'.
The unit tests must cover all lines of code included in the AccountManager class, resulting in 100% code coverage.
Run your test class at least once (via 'Run All' tests the Developer Console) before attempting to verify this challenge.
I getting this error:
Challenge Not yet complete... here's what's wrong:
Executing the 'AccountManager' method failed. Either the service isn't configured with the correct urlMapping, is not global, does not have the proper method name or does not return the requested account and all of its contacts.

Best Answer chosen by Pablo Ledesma 8Hi Pablo,
The requirement for the challenge is to return Account and its related contacts, which can be achieved using one SOQL query. I am sharing the code for my apex class that successfully passed the challenge.
While your code did provide the evrything that was required the JSON returned in the case of single SOQL is different as compared to your JSON.
Hope this helps,
Sandeep

Heiko Kramer How to NOT add a Key with empty Value to a Map?
// Map to keep key (caregory) and value related to each other
Map<String, String> mailValues = new Map<String, String>();
// Seperate keys and values and put it in the map
List<String> listOfLines = plainText.split('\n');
for(String line : listOfLines){
String key = line.substringBetween('<', '>');
String value = line.substringBetween('<' + key + '>', '</' + key + '>');
if (key != null) { // this works just fine, null key not added
// if (key != null || value != null){ // works partial, null key not added, but empty value added
// if (key != null || value != ''){ // doesn't work at all, null key + empty value get added
mailValues.put(key, value);
}
Hi guys, I'm getting tagged values per mail in this format:<key>value</key>
<key2>value</key2>
Somethimes there are linebreaks, so I get a null key added to the map. Got that solved with "key != null".
But I'm struggling with excluding no-values like <key></key>.
Probably easy, but I'm absulte beginner … can someone give me a hand here?
Best Answer chosen by Heiko KramerHi,
Why not to use only , If (value != null) { ,in the second If statement. Using both key & value in the If statement will generate the key, value pair if any one is true.

Challenge Not yet complete... here's what's wrong: The packingListItem Lightning Component's attribute tag doesn't exist or its attributes are not set correctly.
Hi, I am having trouble with the "Attributes and Expressions" module from trailhead.
Here is the challenge:
Create a Lightning Component to display a single item for your packing list.
The error that I am getting is: "Challenge Not yet complete... here's what's wrong:

With this, I tried to create another component, with the name "packingListItem", but It didn't work.
Can anyone help me?
Thanks,
Here is the challenge:
Create a Lightning Component to display a single item for your packing list.
- Create a component called campingListItem that displays the name (ui:outputText) and the three custom fields using the appropriate output components.
- Add an attribute named 'item' for type Camping_Item__c.

<aura:attribute name="item" type="<my_domain>__Camping_Item__c"/>
<ui:outputText value="{!v.item.Name}"/>

Roman Rauer Using API's without authentication
Hi there :)
i'm currently working on an native Android app for my company and ran into some problems with Salesforce lately.
I hope i can find some help here.
What i want to achieve:
The company has a lot of Accounts in Salesforce with 3 important fields for the app: Name, Business (Workshop or Parts Dealer) and location(latitude, longitude)
I would like to show those Accounts(Workshops/Parts Dealers) as markers on a google map in my Android app based on a radius around the user's current location. So it would be more than sufficient to get the data as JSON or XML(i read about sObjects, which would be nice too)
The app will be freely available on Google Play Store and every user should be able to see all the Workshops/Parts dealers around the world.
The problem i'm facing is that i can't find a way to fetch the data inside my app without authenticating every user with a Salesforce-Login.
Which API is the best to use in this case?
It would be so awsome if anybody could help me with this problem.
What i tried so far:
- SalesforceMobileSDK: If i extend SalesForceApplication i always end up with the Salesforce-Login Screen.
It seems that every client has to be authenticated for API-calls to work. I tried using the method "peekUnauthenticatedRestClient", but this method only works on full path URL's(e.g. "https://api.spotify.com/v1/search?q=James%20Brown&type=artist"), which isn't really practically for my Use-case.
- I feel like i read nearly all docs about salesforce api, but can't quite get my head around how to solve this problem, although it seems like to be a pretty common use-case.
- would a salesforce-apex method which would select all records inside a set radius around the user's location be accessable without authentication?
Thanks for your help in advance!

Best Answer chosen by EQ AdminI find some errors and the code does not compile (i mocked all of your custom object but anyway there might be some sintax errors).
Consider to split some "iterative tasks" in an helper (static) class, since your Rest service might grows in future, developers (you too ofc) may encounter difficulties to maintain that. For example, that part in which lineItems are collected and then modified can be delegated to the helper class to enhance code readability.
Further little optization can be done storing fixed numbers/strings in costants but I guess that there are not any improvements that significately reduce the execution time, I mean the optimization I will want to see here is in code readability first. Hope I helped you to solve your cancerns!
