class-transformer not working properly #169
Comments
Duplicate of #160 |
@necm1 It seems there is an issue with toObject, which we need to figure it out. |
I have spent sometime with this, and still no idea what's causing this issue. |
@necm1 Please how did you add |
You need to use the import {PaginateModel} from 'mongoose';
/**
* BookService constructor
*
* @constructor
* @param {PaginateModel<Book & Document>} book
* @param {CacheService} cacheService
* @param {AuthorService} authorService
*/
constructor(
@InjectModel(Book.name) private book: PaginateModel<Book & Document>,
private readonly cacheService: CacheService,
private readonly authorService: AuthorService
) {} @aravindnc some time passed - did you find any solution / fix for this issue? |
this solution is working for me. @Schema({
collection: 'services',
timestamps: true,
toJSON: {
virtuals: true,
transform: (doc, ret) => {
ret['id'] = ret['_id'];
if (ret['fee'] && ret['fee'].length > 0) {
ret['fees'] = ret['fee'][0]['ref'];
}
},
},
})
export class Service implements IService {
@Prop({
type: mongoose.Schema.Types.ObjectId
})
@Exclude()
_id: string;
@Prop({
type: mongoose.Schema.Types.ObjectId
})
id: string;
@Prop({ type: String })
service: string;
@Prop({
type: String,
enum: EServiceType,
})
type: EServiceType;
@Prop({
type: String,
enum: EServiceType,
})
vehicleType: EServiceType;
@Prop({
type: mongoose.Schema.Types.ObjectId,
ref: 'Service',
})
@Type(() => Service)
parent?: string | undefined;
@Exclude()
@Prop([
{
type: ServiceFee,
},
])
@Type(() => ServiceFee)
fee: ServiceFee[];
@Prop({
type: mongoose.Schema.Types.ObjectId,
ref: ServiceFeeComponent.name,

@Type(() => ServiceFeeComponent)
fees: ServiceFeeComponent[];

@Prop({

})
updatedAt: Date;
@Prop({
type: String,
})
created_by: string;
@Prop({
type: String,
})
updated_by: string;
constructor(partial: Partial<Service>) {
Object.assign(this, partial);
}
}
export const ServiceSchema = SchemaFactory.createForClass(Service);
ServiceSchema.plugin(mongoosePaginate); public getServices = async (query: FilterQuery<Service>, options: PaginateOptions) => {
return this._serviceModel
.paginate(query, options)
.then((services: PaginateResult<Service>) => ({
...services,

Hey!
I'm actually facing an issue using
class-transformer
using NestJS. I try to exclude some properties for my response, but getting following error:Method I'm using to create paginate:
The following entities
User
&Profile
is a normalScheme
which looks for example like this:How I create the response:
Even without using the
transform
object in mypopulate
I'm facing the same error.I've an example where it works using
findOne()
(Excluding properties works):The text was updated successfully, but these errors were encountered:
