Handling Multiple Conditions in a Microflow for Patch Request Validation

0
Body: Hi Mendix Community, I'm working on implementing patch request validation in my Mendix application, and I need to handle multiple field conditions within a single microflow efficiently. Here's the scenario: I have an entity with several attributes (e.g., Name, Email, PhoneNumber, etc.). Each attribute requires different validation logic (e.g., Email should have a valid format, PhoneNumber should match a specific pattern, and Name shouldn't be empty). I want to perform all these checks within a single microflow when processing a patch request to ensure that only valid fields are updated. My current approach is to use a series of decision nodes for each validation rule, but this results in a very complex and hard-to-maintain microflow as the number of fields grows   Any insights, tips, or examples would be greatly appreciated! Thanks in advance for your help!

Hi,

   Instead of handling all validations in a single microflow, consider breaking down the logic into smaller, reusable sub-microflows. Each sub-microflow could handle validation for one or a group of related fields  Add rules for the valid strin,email,telephone,integer,date and time

(e.g., one for email validation, another for name validation). This modular approach helps keep the main microflow simpler.

Hi Pushpendra, 

 

https://docs.mendix.com/refguide/setting-up-data-validation/--------go through the link for clear validation proccess.

Default Set for rules for  possible possible:You’re setting default values or handling for data types like String, Decimal, Email, and Phone number.

Validation Flow:The second image you mentioned likely shows a flow to validate entities (perhaps how data integrity or correctness is checked within the model).

Subflow Creation for Validation:To create a validation subflow:

Start by creating a variable (True/False).Apply a condition to check the attribute. If the condition is True, continue to the next step. If False, merge the validation feedback.After checking all the conditions, the variable is evaluated to see whether the validation passes or fails.
