parasolr

parasolr is a lightweight python library for Apache Solr indexing, searching and schema management with optional Django integration. It includes a Solr client (parasolr.solr.SolrClient). When used with Django, it provides management commands for updating your Solr schema configuration and indexing content.

• 
• 

Tested against Python 3.9-3.11, Solr 8.6 and 9.2, and Django 3.2-5.0 and without Django.

Installation

Install released version from pypi:

pip install parasolr

To install an unreleased version from GitHub:

pip install git+https://github.com/Princeton-CDH/parasolr@develop#egg=parasolr

To use with Django:

• Add parasolr to INSTALLED_APPS

• Configure SOLR_CONNECTIONS in your django settings:

  SOLR_CONNECTIONS = {
      'default': {
      'URL': 'http://localhost:8983/solr/',
      'COLLECTION': 'name',
      # Any configSet in SOLR_ROOT/server/solr/configsets.
      #   The default configset name is "_default" as of Solr 7.
      #   For Solr 6, "basic_configs" is the default.
      'CONFIGSET': '_default'
      }
  }
  

• Define a SolrSchema with fields and field types for your project.

• Run solr_schema manage command to configure your schema; it will prompt to create the Solr core if it does not exist.

Note

The SolrSchema must be imported somewhere for it to be found automatically.

Development instructions

This git repository uses git flow branching conventions.

Initial setup and installation:

• Recommmended: create and activate a Python 3.x virtualenv:

  python3 -m venv parasolr
  source parasolr/bin/activate
  

• Install the package with its dependencies as well as development dependencies:

  pip install -e .
  pip install -e '.[dev]'
  

Install pre-commit hooks

Install configured pre-commit hooks (currently black and isort):

pre-commit install

Styling was instituted in version 0.8; as a result, git blame may not reflect the true author of a given line. In order to see a more accurate git blame execute the following command:

git blame <FILE> --ignore-revs-file .git-blame-ignore-revs

Or configure your git to always ignore the black revision commit:

git config blame.ignoreRevsFile .git-blame-ignore-revs

Unit testing

Unit tests are written with pytest but use some Django test classes for compatibility with Django test suites. Running the tests requires a minimal settings file for Django-required configurations.

• Copy sample test settings and add a secret key:

  cp ci/testsettings.py testsettings.py
  python -c "import uuid; print('\nSECRET_KEY = \'%s\'' % uuid.uuid4())" >> testsettings.py
  

• By default, parasolr expects Solr 8. If running tests with an earlier version of Solr, either explicitly change MAJOR_SOLR_VERSION in your local testsettings.py or set the environment variable:

  export SOLR_VERSION=x.x.x
  

• To run the test, either use the configured setup.py test command:

  python setup.py test
  

• Or install test requirements in and use pytest directly:

  pip install -e '.[test]'
  pytest
