Using Expressions in Validation Constraints

[Seb33300]

Hi,

It seems to not be possible at this time.

Instead of using the @Assert\Expression constraint, sometimes, it could be great to support expressions directly in others constraints like:

/**
 * @Assert\Range(
 *      min = "this.startDate",
 *      max = "this.startDate + 10 days"
 * )
 */
 protected $endDate;

/**
 * @Assert\GreaterThan("this.startDate")
 */
protected $endDate;

// etc...

supporting expressions directly like than would be hard to handle it in a BC way (I see lots of weird edge cases coming).

IIRC, there was already some discussion around this before, but I cannot find the right issue anymore right now.

What about in-lined annotations?

/**
 * @Assert\Range(
 *      min = @Assert\ExpressionValue("this.startDate"),
 *      max = @Assert\ExpressionValue("this.startDate + 10 days")
 * )
 */

And technically in these cases it's properly a good idea to create a custom Constraint/Validator then doing everything with expressions.

I think this would simplify constraints quite a bit tbh

Thank you for this suggestion.
There has not been a lot of activity here for a while. Would you still like to see this feature?

[carsonbot]

Friendly ping? Should this still be open? I will close if I don't hear anything.

While I agree with #21476 (comment) I fail to see how this could be implemented. Does anyone have a good idea and would like to give it a try?

closing for now, PR welcome if someone would like to give this a try though
