Summary

Fixes a bug where the search query was cleared when using the bottom pagination on the All Hosts page.

Root Cause

HostsIndex uses the replacementResponse pattern, which creates two separate params states:

  • API response has correct page/perPage values from the server
  • HostsIndex's params state was stale (not synced with API response)
  • Bottom pagination used HostsIndex's stale params, causing search to be lost

Solution

Merge the API response's page and perPage values into the params object during render:

params={{ ...params, page, perPage }}

This approach:

  • Follows React best practices (no useEffect needed)
  • Preserves search/filters from params state
  • Overrides stale page/perPage with current API response values

Changes

  • Modified HostsIndex/index.js to merge API response values into params prop
  • Added HostsIndex/index.test.js to verify the params merging behavior

Test Plan

  • Tested in browser: search with multiple pages → click bottom pagination → search persists ✅
  • New unit test passes and fails without the fix ✅
  • All TableIndexPage tests pass (no regressions) ✅
  • Linting passes ✅

Hi @jeremylenz, are you sure these changes address the issue? I'm still seeing the same results as before.

@nofaralfasi Ok, I think this should work better. See if it works for you

When using the All Hosts page with replacementResponse pattern, the
bottom pagination was clearing the search query because HostsIndex
maintained a separate params state that wasn't synced with the API
response values.

This fix merges the API response's page and perPage values into the
params object during render, ensuring the bottom pagination displays
the correct page number while preserving the search query. This
follows React best practices by calculating values during render
instead of using useEffect.

Also adds a test to verify the params merging behavior.

Fixes #38858 - Fix search cleared on bottom pagination (revised)

The previous fix had two issues:
1. Both per_page and perPage appeared in URL params
2. Search was still being cleared on bottom pagination

Root cause: HostsIndex's params state doesn't sync with search changes
made through TableIndexPage's SearchBar. The API response contains the
current search query, page, and perPage, but they weren't being merged
into the params passed to Table.

Solution: Merge fresh values from API response into params:
- page: current page number
- per_page: current per-page value (using snake_case, not camelCase)
- search: current search query

This ensures:
- Only snake_case per_page in URL (no duplicate perPage)
- Search query always preserved when using bottom pagination
- Page/perPage are always current values from API response

Fixes #38858 - Prevent duplicate perPage/per_page in Table params

Previous fix had two remaining issues:
1. Test was failing because mock API response lacked search field
2. Both perPage (camelCase) and per_page (snake_case) appeared in params

Changes:
- Added search field to mock API response in test
- Destructured and excluded stale perPage from params before spreading
- This ensures only per_page (snake_case) appears in Table params
