Function validate_mutation_data 

pub fn validate_mutation_data(
    data: &HashMap<String, Value>,
    model_admin: &dyn ModelAdmin,
    is_update: bool,
) -> Result<(), AdminError>

Available on server only.

Validates mutation data against model admin configuration.

This function performs the following checks:

1. Size limits (field count, string length, total payload)
2. Field allowlist (only known fields are allowed)
3. Readonly field enforcement (readonly fields cannot be modified)

Arguments

• data - The mutation data to validate
• model_admin - The model admin configuration
• is_update - Whether this is an update operation (blocks pk_field modification on updates only)

Errors

Returns AdminError::ValidationError if validation fails.

Examples

use reinhardt_admin::server::validation::validate_mutation_data;

let mut data = HashMap::new();
data.insert("name".to_string(), serde_json::json!("Alice"));

validate_mutation_data(&data, &model_admin, false)?;
