Package: csc-validator-be-cin
CIN-validatorThe CIN validator is an open source, volunteer built tool that allows users to validate CIN census data year round via the command line, or using the browser based front end (URL HERE). It also provides a framework which other validation tools can easily be built on top of.The functions are documented using sphinx format so that a docs website can be auto-generated if need be. Also, there is an increased use of python type-hints as a form of intrinsic documentation. This does not apply to test functions as they neither receive nor return data, in the strict sense.
More extensive documentation can be found here:https://data-to-insight.github.io/CIN-validator/SetupThis repo can be opened and run in a codespaces instance or cloned locally usinggit clone https://github.com/data-to-insight/CIN-validator.gitIf it is cloned locally, usepre-commit installto install the pre-commit hooks.RunTo test that all the rules pass their Pytests and will validate data as expected:python -m cin_validator testTo list all rules that are present:python -m cin_validator listTo run rules on a file and generate a table of error locations:python -m cin_validator run <path to test data>-To run rules on the sample data and explore the output of the CLI:python -m cin_validator run path/to/your/cin/validator/CIN-validator/fake_data/fake_CIN_data.xmlTo run rules on a file and select an instance of an error based on its ID:python -m cin_validator run <path to test data> -e "<ERROR_ID as string>"To convert a CIN XML file to it's respective CSV tables:python -m cin_validator xmltocsv <path to test data>Yearly tool updatesupdate rule resourcesRunpython get_uk_holidays.pyin the command line. This fetches the latest values of bank holidays intocin_validator\england_holidates.py(don't edit this file directly) for the rules that need them. Remember to convert \ to / if you are using a unix operating system.update rulesIf any rules have been added or changed with respect to the previous year, create files for them in a rule folder named after the new validation year. For example, new or added rules for the 2023/24 validation year should be created in a folder namedcin2023_24. Do not copy over rules that haven't changed.Theinit.py file contains the code that pulls in rules from the previous year and modifies them to meet the current year's specification. Copy across that init file whenever a folder for a new collection_year is created. Change the import to the name of the previous year's folder.If the new specifications require that some rules are deleted, add their codes as strings to thedel_listarray in the current year's init file. Do not delete the rules manually.Any new rules or modified rules should be added by creating a file for each rule and writing the modified code or new code. Even for small modifications, create a new file for the rule in the year where the modification was made instead of going backwards into the previous years and editing the original file.To run the modified set of rules from the command line interface, you can use the-ror--rulesetflag to specify the name of the rule folder that you wish to run. Otherwise, feel free to update the defaults of the commands so that they point to the new year's folder instead. For example, changecin2022_23tocin2023_24.make changes available to userdelete thedistfolder completely.runpoetry install(installs project dependencies) and thenpoetry shell(ensures project runs in controlled environment) in the command line. You might have already done this when updating the rules.check that validation rules work as expected (pass) when you runpoetry python -m cin_validator testin the command line.Then runpoetry buildin the command line. You will see that this creates a newdistfolder.take the.whlfile from the dist folder in this repo, go to thepublic\bin\distlocation in the frontend repo, delete the cin...whl file in it and add this one.Do a pull request to the frontend repo, containing your changes. When that is merged in, the tool will be updated automatically so that your rules updates from the backend (which were zipped up in the wheel file), are now publicly available.You can watch the deployment process in theActionstab on Github when your pull request is merged to the frontend.All done !
