0.16

2018-09-10

Note

This release contains minor backwards incompatible changes. You might need to update your code if you have been making use of nested search.

Old way of declaring nested search fields

search_nested_fields = {
    'country': ['name'],
    'country.city': ['name'],
}

New way of declaring nested search fields

search_nested_fields = {
    'country': {
        'path': 'country',
        'fields': ['name'],
    },
    'city': {
        'path': 'country.city',
        'fields': ['name'],
    },
}
  • Changes in nested search. This affects usage of both historical SearchFilterBackend and CompoundSearchFilterBackend. Update your code accordingly.
  • Take meta property using of the document Meta into consideration.

2018-08-22

  • More tests.
  • Fixes in docs.

  • Unified the base BaseSearchFilterBackend class.
  • Minor clean up and fixes in docs.
  • Upgrading test suite to modern versions (pytest, tox, factory_boy, Faker). Removing unused dependencies from requirements (drf-extensions).

0.13.1

2018-07-26

  • Minor fix in suggesters on Elasticsearch 6.x.

0.13

2018-07-23

Note

Release dedicated to Guido van Rossum, the former Python BDFL, who resigned from his BDFL position recently. Guido knew it better than we all do. His charisma, talent and leadership will be certainly missed a lot by the community. Thumbs up again for the best BDFL ever.

  • The SimpleQueryStringSearchFilterBackend backend has been implemented.
  • Minor fixes in the MultiMatchSearchFilterBackend backend.

0.12

2018-07-21

  • New-style Search Filter Backends. Old style SearchFilterBackend is still supported (until at least version 0.16), but is deprecated. Migrate to CompoundSearchFilterBackend. MultiMatchSearchFilterBackend introduced (the name speaks for itself).
  • From now on, your views would also work with model- and object-level permissions of the Django REST Framework (such as DjangoModelPermissions, DjangoModelPermissionsOrAnonReadOnly and DjangoObjectPermissions). Correspondent model or object would be used for that. If you find it incorrect in your case, write custom permissions and declare the explicitly in your view-sets.
  • Fixed geo-spatial geo_distance ordering for Elastic 5.x. and 6.x.
  • Fixes occasionally failing tests.

0.11

2018-07-15

Note

This release contains backwards incompatible changes. You should update your Django code and front-end parts of your applications that were relying on the complex queries using | and : chars in the GET params.

Note

If you have used custom filter backends using SEPARATOR_LOOKUP_VALUE, SEPARATOR_LOOKUP_COMPLEX_VALUE or SEPARATOR_LOOKUP_COMPLEX_MULTIPLE_VALUE constants or split_lookup_complex_value helper method of the FilterBackendMixin, you most likely want to run your functional tests to see if everything still works.

Note

Do not keep things as they were in your own fork, since new search backends will use the | and : symbols differently.

Examples of old API requests vs new API requests

Note

Note, that | and : chars were mostly replaced with __ and ,.

Old API requests

http://127.0.0.1:8080/search/publisher/?search=name|reilly&search=city|london

http://localhost:8000/api/articles/?location__geo_polygon=40,-70__30,-80__20,-90___name,myname__validation_method,IGNORE_MALFORMED
  • SEPARATOR_LOOKUP_VALUE has been removed. Use SEPARATOR_LOOKUP_COMPLEX_VALUE and SEPARATOR_LOOKUP_COMPLEX_MULTIPLE_VALUE instead.
  • SEPARATOR_LOOKUP_NAME has been added.
  • The method split_lookup_complex_value has been removed. Use split_lookup_complex_value instead.
  • Default filter lookup option is added. In past, if no specific lookup was provided and there were multiple values for a single field to filter on, by default terms filter was used. The term lookup was used by default in similar situation for a single value to filter on. It's now possible to declare default lookup which will be used when no lookup is given.
  • Removed deprecated views module. Import from viewsets instead.
  • Removed undocumented get_count helper from helpers module.
