Partially fixes #6155, as it is only the basic schema import/export mechanism.

Adds Schema Config import for full schema-localization JSON exports. Note that it can take over a minute to restore a schema as it performs a lot of updates to accomplish.

  • Adds an Import button beside Export in Schema Config.
  • Prompts users to download a backup before importing.
  • Accepts downloaded schema exports and applies localized captions/descriptions for all fields and tables.
  • Skips unknown tables, fields, and unavailable formatters, pick lists, and web links to prevent invalid assignment.
  • Performs all updates atomically so that things are not left partially applied. Standard permissions are enforced based on user policies for the splocale* tables. Preserves table/field permission checks, locking, audit logging, and ModifiedByAgent is linked to the user who initiates the action.
  • Validates schema structure, supported value types, and the existing two-character language/country format.

Import Button:

Import Dialog (after file selection):

Here is where the user can choose to make a backup before importing the new schema. After import, the user will see a loading dialog which will disappear once the import completes:

Error (invalid JSON):

There are some automatic tests, which cover:

  • Importing values and localized strings.
  • Skipping unknown tables and fields.
  • Rejecting malformed schema JSON and invalid value types.
  • Rejecting invalid language formats without writing data (based on what we allow now, e.g., en-us)
  • Skipping missing formatter, pick-list, and web-link references.
  • Preserving atomic writes through the existing CRUD operations.

Manual Testing

This is best tested by exporting various schema config files from different databases. Please test this with complex schemas that have custom pick lists and web links assigned, then import those exports into other databases missing those resources. Test exporting the current database and importing the export you just made while verifying the schema still has all the pick lists and captions assigned the same.

  • Open Schema Config for a collection using a user that has schema-edit permissions.
  • Confirm Export button (in top left) downloads the current full schema-localization JSON.
  • Make changes to various fields in Schema Config and verify Import is disabled until it has been saved.
  • Select Import and download the current schema backup when prompted.
  • Select a full schema export from another database, or reset the schema by importing the config/common/schema_localization_en.json.
  • Review the changed tables and fields, then click Save.
  • Refresh Schema Config and confirm the imported captions and values remain.
  • Try an invalid JSON file (export a query if you need one) and confirm the import is rejected without making any changes to the schema.

Summary by CodeRabbit

  • New Features

    • Added schema localization import through the Schema Configuration interface.
    • Users can select a JSON file, review warnings and limitations, download a backup, and confirm changes.
    • Import controls are unavailable to read-only users or while changes are pending.
    • Imports validate schema data and language settings before applying updates.
  • Bug Fixes

    • Invalid files and unsupported content now display an error without saving partial changes.

📝 Walkthrough

Walkthrough

The PR adds schema localization import support. The backend validates and applies imported JSON data transactionally. The Schema Config interface selects files, confirms imports, submits them for the active language, and displays errors.

Changes

Schema localization import

Layer / File(s) Summary
Schema import validation and operation building
specifyweb/backend/context/views.py
The backend validates schema values, resolves references, matches existing containers and items, and creates localization update operations.
Import endpoint and API validation
specifyweb/backend/context/urls.py, specifyweb/backend/context/views.py, specifyweb/backend/context/tests/test_schema_localization_import.py
The POST endpoint validates requests, applies updates atomically, returns errors for invalid input, and is covered by API tests.
Schema Config import flow
specifyweb/frontend/js_src/lib/components/SchemaConfig/*, specifyweb/frontend/js_src/lib/localization/schema.ts, specifyweb/frontend/js_src/lib/components/ChooseCollection/index.tsx, specifyweb/frontend/js_src/lib/components/Core/Main.tsx, specifyweb/frontend/js_src/lib/components/Router/Routes.tsx, specifyweb/frontend/js_src/lib/components/WbToolkit/GeoLocate.tsx
The interface supports JSON file selection, import confirmation, backup download, submission, error display, and localized import messages. The remaining frontend changes reformat existing code without changing behavior.

Merge Risk: 🟡 Moderate · up to f69cc

Schema imports can synchronously update many records in one request, but the current implementation has no explicit bounds on request size, operation count, duration, or concurrency, and concurrent imports may race when creating missing localized values. This could tie up application workers or database locks and cause import failures, so the change needs explicit owner acceptance or mitigation before merge.

Explanation

The PR implements the core JSON import workflow, validation, localization updates, backup warning, and error handling [#6155]. However, the provided changes cover schema-localization imports only and do not show the required choice between All Customizations and Localizations Only, explicit language selection, user documentation, or a successful post-import confirmation.

Resolution

Add the required import-mode and language selection controls, implement or explicitly support both import modes, add successful completion notification, and provide the required user documentation for supported and unsupported configuration elements [#6155].

Full details: Out of Scope Changes check

Explanation

The schema import changes are in scope, but formatting-only changes in ChooseCollection/index.tsx, Core/Main.tsx, Router/Routes.tsx, and WbToolkit/GeoLocate.tsx are unrelated to the linked schema import objective [#6155].

Full details: Testing Instructions

Explanation

The testing instructions are not fully accurate for the implemented import flow. The checklist says to review changed tables and fields and then click Save, but SchemaConfigLayout sends the import in confirmImport, and the backend applies it immediately. The success path then reloads the page; onSave is only enabled when anyModified is true, so there is no post-import Save step. The claimed automated atomicity coverage is also not demonstrated by test_schema_localization_import.py: its invalid cases fail validation before any write and do not force a write failure after an earlier successful operation. The new SchemaConfigHeader and SchemaConfigLayout UI paths have no corresponding frontend tests.

Resolution

Update the manual checklist to say: select the file, download the backup if required, click Continue Import, wait for the loading state to finish, and verify the reloaded schema. Remove the post-import Save instruction. Add explicit checks for the confirmation dialog, loading completion, invalid JSON/incompatible schema errors, missing formatter/pick-list/web-link handling, and read-only or permission-restricted users. Add or document an integration test that causes a failure during a multi-operation import and verifies rollback, and document how to run the backend and frontend tests.

Importing a schema in another language should trigger some sort of warning message for the user.

Everything passes except that I got an error when importing this json file. It took some minutes before it showed the error message. However it passes once I imported the export from another database.config/common/schema_localization_en.json

I was also able to see the invalid JSON rejection when uploading query export:

Normalize locale keys before the lookup.

_schema_import_string uses exact country matching. A countryless import can miss existing rows with country='', and an en-US import can miss rows with country='US'. The importer can then create duplicate Splocaleitemstr rows. Match the repository’s NULL/blank and lowercase locale forms, and add regression tests.

Testing Instructions

  • Open Schema Config for a collection using a user that has schema-edit permissions.
  • Confirm Export button (in top left) downloads the current full schema-localization JSON.
  • Make changes to various fields in Schema Config and verify Import is disabled until it has been saved.
  • Select Import and download the current schema backup when prompted.
  • Select a full schema export from another database, or reset the schema by importing the config/common/schema_localization_en.json.
  • Review the changed tables and fields, then click Save.
  • Refresh Schema Config and confirm the imported captions and values remain.
  • Try an invalid JSON file (export a query if you need one) and confirm the import is rejected without making any changes to the schema.

As suggested, I have pulled from multiple databases in testing this PR. For documentation purposes, those databases were KU Fish, OJMNH, and KU Entomology. I could transfer the KU Fish and Entomology schema configs just fine, but when I moved to the OJMNH database, I received errors that the json file was not supported. I originally thought this was due to the difference in collections, but the import still did not work.

The process of importing in general seems very slow, so perhaps adding some sort of loading bar or estimated time to completion could be a beneficial addition.

When checking the Developer Tools, I believe I found something that could be tied to why that it is loading long while importing, from the screenshots that I took. It seem to fail to send request and kept throwing a 421 error, the error might be on the API call you're making when importing the JSON file
