KHi @tingadev. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

It appears that the
Here is a conceptual example of how you might add the
```typescript
// mapOperator.ts
import { CondOperator } from '@nestjsx/crud-request';
It appears that the
nnullmapOperator utility for the nestjsx-crud provider in refine. This issue has been identified and discussed in the refine community.Steps to Address the Issue
- **Identify the Missing Mapping:**According to the **Github Issue #4805** (<https://github.com/refinedev/refine/issues/4805>), the `nnull` operator is not mapped in the `mapOperator` utility. You can see the relevant part of the discussion **here** (<https://github.com/refinedev/refine/issues/4805>).
- **Implementation Suggestion:**The `nestjsx-crud` supports the `nnull` operator, and it can be implemented using the `CondOperator.NOT_NULL` utility. This was confirmed by a contributor in the same issue.
- **Contributing to Refine:**If you would like to contribute to refine by adding this feature, the team is open to contributions and willing to help you through the process.
Here is a conceptual example of how you might add the
nnullmapOperator utility:```typescript
// mapOperator.ts
import { CondOperator } from '@nestjsx/crud-request';
Kconst mapOperator = (operator: string) => {
switch (operator) {
case 'eq':
return CondOperator.EQUALS;
case 'ne':
return CondOperator.NOT_EQUALS;
case 'lt':
return CondOperator.LOWER_THAN;
case 'gt':
return CondOperator.GREATER_THAN;
case 'lte':
return CondOperator.LOWER_THAN_EQUALS;
case 'gte':
return CondOperator.GREATER_THAN_EQUALS;
case 'in':
return CondOperator.IN;
case 'nin':
return CondOperator.NOT_IN;
case 'contains':
return CondOperator.CONTAINS;
case 'ncontains':
return CondOperator.NOT_CONTAINS;
case 'between':
return CondOperator.BETWEEN;
case 'nbetween':
return CondOperator.NOT_BETWEEN;
case 'null':
return CondOperator.IS_NULL;
case 'nnull':
return CondOperator.NOT_NULL; // Add this line
// Add other cases as needed
default:
throw new Error(
}
};
```
