Just saw the monthly update from @mdubakov and it inspired this feature request. [image] The required fields (above) is a good first step in what we’re missing in our workspace, which is what I would call validations. Validation is where a user is not allowed to take certain actions unless another condition is fulfilled. A few examples: Only allow updating to state “done” when “rich text” field is not empty. Only allow creating a todo if the deadline is also entered When disapproving something (state = disapproved), a text modal appears where you need to state the reason why it’s disapproved. Forcing certain items to be marked as done in a certain order. Ideal for checklists, where you want somebody not to finish task 2 before task 1 is done. Only certain permission groups are allowed to update the budget field of a project Some of these things are already possible with a bit of workaround, as @ChrisG already greatly helped us with. But would be ideal if this was natively possible, on a per-field basis. It probably intertwines quite a bit with permissions and automations, and maybe most of this is already possible, but I felt it deserved it’s own thing.

I also would like to see the integration of Conditions. I don’t know if adding that at a Field level is the best solution but at least if it can be added in Automation, this will already be a good step forward in my opinion.

Validation Rules development started

Hi Fibery, So far I’ve seen alot of great things in Fibery, but a big blocker for me actual moving company data inside is the lack of field validation and unique fields. I need the ability to make any field I create unique, so that an error pops up or I’m simply unable to input a new row if that field is a duplicate. I also need the ability to do more complex field validation, such as field A can’t be x when field B is y. Without these things there’s a very big risk of data duplication and errors. Thanks and great job so far with this tool!

If you search this forum for “unique” you will find that there has been some discussion on this topic, including some ways to enforce/warn about uniqueness violations.

Unique fields and fields validation (via formulas for example) would be great :+1:

Hello. I can’t find this in examples and settings - please help. I want to implement validation when entering new row into a table: e.g. IF field A is OPTION1 then field B and C should be not empty, IF field A is OPTION2 then field D and F should be not empty, and so on. Is it somehow possible? If not - can I at least have formula that will do the same and if it is FALSE displays ERROR label/text?

Hi, Konstantin :slight_smile: We would suggest boolean formula (checkbox) and color-coding on top There is no need in the If formula - just a combination of and/or showing boolean Btw, if you could share with us your case with details, there is a chance, that we can find a better solution :wink:

re: Btw, if you could share with us your case with details, there is a chance, that we can find a better solution Validation is important part of ANY workflow. Some examples: allow only tasks with Estimate be scheduled. allow only tasks with Estimate and Scheduled to be worked on and receive work logs allow only correct financial transaction with all required fields to be created etc

Some update of validation rules development

Hey! Quick question: This looks very similar to automations. When “Previous Value” is released, what would be the difference between validation vs an automation that checks for update, has conditions and then sets the field to its previous value if the conditions are true? From my understanding: The error message showing. Ability to set validation/filters using formula (rules only use the no-code filters) I would love to see these things in rules as opposed to a separate tab. But of course, I might be missing something.
