Package: govtech-csg-xcg-viewpermissions
govtech-csg-xcg-viewpermissionsThis package belongs to theeXtended Code Guardrails (XCG)project, which consists of a series of packages that harden the Django web framework to prevent common web application vulnerabilities.Specifically, the View Permissions package modifies Django's default behaviour such that all views are "private" by default (i.e. inaccessible to all, whether authenticated or not). This acts as an extra layer of defense against coding mistakes or misconfigurations, forcing developers to explicitly define permissions for each view before they can be accessed. Access is given using Django's built in authentication and authorization system - for example through decorators such asdjango.contrib.auth.decorators.login_required- which should be familiar to existing Django developers.Do note that the README in this repository is intentionally limited in scope and is catered towards developers. For detailed instructions on installation, usage, and community guidelines, please refer to the published documentation athttps://xcg.tech.gov.sg.Security-related mattersFor instructions on how toreport a vulnerability, refer to theofficial documentation website.Additionally,enable email alerts for security issues by "watching" this repository. The "watch" button can be found near the top right corner of this repo's home page, and there are various options for configuring notification volume. To receive security alerts, either enable notifications for"All Activity"or"Custom -> Security alerts".Installing development dependenciesBefore building or testing the package, or committing changes, install the development dependencies into a virtual environment:# In the project root directorypython-mvenv.venv&&source.venv/bin/activate

pythonmanage.pytestRunning pre-commit hooksNote: This section is only relevant if you intend to contribute codeThis project uses thepre-committoolto run Git pre-commit hooks for linting and code quality checks. Thepre-committool itself should have been installed along with thedevelopment dependencies. After cloning the repositoryfor the first time, run the command below to "install" the Git hooks:pre-commitinstallThe command above creates a file.git/hooks/pre-commit, which defines the shell commands to run before any Git commit is created.Subsequently, any invocation ofgit commitwill trigger the commands, rejecting the commit if there are linting errors. Issues should be automatically fixed, but you will need to re-stage the changes before attempting the commit again.For a list of hooks run bypre-commit, see itsconfiguration file.
