Cryptographic Failures is the second most important category of vulnerabilities listed in the OWASP Top 10 for 2021. That’s why in the past weeks I decided to invest some time creating content to help you with signature and encryption techniques in Apex.Continue reading “Signature & Encryption Recipes in Apex”

Visualforce order of execution I: GET requests
Following with a previous post about triggers and order of execution, I want to review in this new post how the order of execution on a Visualforce page is. This time we need to distinguish between two different cases: Visualforce pages that perform a get request and those which perform a post request.
In this post I will explain how GET requests work. I will elaborate a second part of the post, talking about POST requests.

Triggers and order of execution
In this post I want to review the order in which things happen when I save a record in Salesforce. This is important to understand if you are an app builder who works automating processes as well as if you are a developer that writes trigger code. Both worlds will converge in the end and affect each other, so you have to bear in mind how Salesforce executes things internally to ensure a correct behaviour of your solution.Continue reading “Triggers and order of execution”
CRUD & FLS
This time I want to talk a bit about CRUD & FLS in Salesforce. What do these acronyms mean? Well… it is the way that we have of allowing or restricting who can create, view, modify or delete objects and fields on the platform.
CRUD – Create / Read / Update / Delete
FLS – Field Level Security (visible, editable, hidden)
Working with datetimes
This time I want to point out some weird behaviours I have learnt with the practice about datetimes in Salesforce. Did you know them?
1. Datetime fields do not store milliseconds.
Currently datetime fields don’t support millisecond precision. Even if you work with Datetime class (which do support millisecond precision), when you store them in database the milliseconds are lost.
This is a problem if you need to work with a high time precision, that can be worked around in some ways, for example storing the Unix time in a number field.
You can vote this related idea if you feel it is an important fact.
