fix-schema-generation-for-list-dict-fields

[ghazi-git]

Use a pattern to correctly describe the attr value in validation errors in all cases.

Specifically, this fixes the incorrect description of the attr value for list serializers and list/dict fields. Taking the example of a list serializer with 1 field named my_field. The validation errors for this field will have the attr value set as 0.my_field, 1.my_field, ...

• Previously, the attr value was described with an enum having a single value INDEX.my_field.
• Now, it shows up as a string with the pattern \d+\.my_field and this pattern correctly described the actual attr value returned by the API 0.my_field, 1.my_field, ...
