adonis js5 验证器有“字母数字”选项吗？

Question

Hi everybody i end of to read the documentation of adonis js for to use "validation rules" but i dont see a option for to validate a "alphanumeric" value(in adonisjs 4.1 this exist but i try to migrate to adonis 5), i have the way of to make this rule but before i need to question ¿Really there not is a alphanumeric validation in validation rules or i need to read the guide again? and ¿there is some platform for ican to send my custom validation rules? Thanks for the answers

Answer 1

Use the regex helper rule to implement an alphanumeric rule.

From the docs. :

{
  username: schema.string({}, [
    rules.regex(/^[a-zA-Z0-9]+$/)
  ])
}

This will allow these:

username10 // --> OK
username // --> OK
Username10 // --> OK

while disallowing these:

user_name // --> BAD
user-name10 // --> BAD
USER@name10 // --> BAD

Now there is a rule called alpha , you can check it out here: https://preview.adonisjs.com/guides/validator/rules#rulesalpha

Or just create a Custom Rule or regex.
