Description

Description

The issue is originally reported via https://github.com/swagger-api/swagger-codegen/issues/4805#issuecomment-280615622

For typescript-angular2:

"Request": {
                "device_type": {
                    "type": "string"
                },
            }
        },

generates:

export interface Request { 
    deviceType?: string;
}

The deserialization does not work as there's no mapping between deviceType and device_type (original attribute name in JSON)

Swagger-codegen version

latest master and 2.3.0

Research direction
Investigate the TypeScript Angular2 template files in the swagger codegen repository to understand how property names are converted from snake case to camelCase. Look for existing mapping mechanisms or configuration options. Review similar issues or PRs for other languages that may have addressed this. The fix likely requires adding a deserialization mapping or using a decorator like @JsonProperty. Check the codegen logic in the default Codegen class for property name handling.
