Expand description

Methods for additional validation. Hint: For custom use, add the Model/Form attribute is_use_add_valid = true. Hint (for models): Remember to use for validate of ignored fields.

Example:

impl AdditionalValidation for UserProfile {
    fn add_validation<'a>(
        &self,
    ) -> Result<std::collections::HashMap<&'a str, &'a str>, Box<dyn std::error::Error>> {
        // Hint: error_map.insert("field_name", "Error message.")
        let mut error_map: std::collections::HashMap<&'a str, &'a str> =
            std::collections::HashMap::new();

        // Get clean data
        let hash = self.hash.clone().unwrap_or_default();
        let password = self.password.clone().unwrap_or_default();
        let confirm_password = self.confirm_password.clone().unwrap_or_default();
        let username = self.username.clone().unwrap_or_default();

        // Fields validation
        if hash.is_empty() && password != confirm_password {
            error_map.insert("confirm_password", "Password confirmation does not match.");
        }
        if !RegexBuilder::new(r"^[a-z\d_@+.]+$")
            .case_insensitive(true)
            .build()
            .unwrap()
            .is_match(username.as_str())
        {
            error_map.insert(
                "username",
                "Invalid characters present.<br>\
                 Valid characters: a-z A-Z 0-9 _ @ + .",
            );
        }

        Ok(error_map)
    }
}
