📝 WalkthroughWalkthroughThe change adds 13 original-language filter settings, exposes them through public settings, provides a reusable filtering hook, and applies the filters across search, discovery, recommendations, similar titles, upcoming lists, trending, and media sliders. ChangesOriginal Language Filtering
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR adds original-language filtering across discovery, search, recommendations, and similar-title views. At the current head, stale filter state, incorrect movie/TV setting selection, and pagination based on unfiltered results can produce incorrect or incomplete results, while labels may not be localized; merge should wait for these bounded correctness issues to be fixed or explicitly accepted.

`@app/pages/_error` as ErrorPage so the existing ErrorPage renders resolve
correctly; no other changes are needed.
Apply the same fix in `@src/components/Discover/DiscoverTvUpcoming.tsx` at line 6:

In `@src/components/Discover/FilterSlideover/index.tsx`:
- Line 208: Update the request-state preparation around
currentSettings.originalLanguage and preparedFilters so language is cleared or
omitted whenever the server-provided originalLanguage is non-empty, preventing
bookmarked or URL-derived language values from reaching useDiscover alongside
it. Keep the existing isDisabled UI behavior for new changes.
In `@src/components/MediaSlider/index.tsx`:
- Line 158: Complete the blacklistVisible call before declaring
blocklistVisibility, ensuring the hasPermission argument list is closed and the
file parses successfully. Keep the existing permission-check flow unchanged.
- Around line 74-76: Update the filtering predicate in MediaSlider to preserve
person results when hideAvailable is enabled by applying availability-status
checks only to movie and tv entries; leave non-title media types untouched so
person cards remain available for rendering.
- Line 89: Fix the filter expression in the MediaSlider component by closing the
preceding titles.filter callback before starting the hideBlocklisted callback,
restoring valid syntax and allowing the application to build.
In `@src/components/Settings/SettingsMain/index.tsx`:
- Around line 85-98: The filter labels in the filters array, along with the
section title and help text in SettingsMain, are hardcoded English strings. Add
localized message descriptors and use intl.formatMessage for all 13 filter names
and the associated title and help text, following the existing settings

- Around line 37-38: Update the useFilterByLanguages options in
src/components/TvDetails/TvRecommendations.tsx lines 37-38 and
src/components/TvDetails/TvSimilar.tsx lines 37-38 to pass movie: false and tv:
true, so TV results are filtered using their configured original-language rules.
In `@src/hooks/useFilterByLanguages.ts`:
- Around line 33-38: Update the settings-update logic in useFilterByLanguages so
originalLanguages is assigned on every update, parsing and trimming
originalLanguage when present and using an empty array when it is empty or
unset; preserve applyFilter behavior.

Please use the discover language multi select instead of the toggles.
Thanks, going to look at that. I get it now. |

Also I'm not sure I understand this PR. Discover Language is a discover setting. It already sets If the goal is restricting what users can request, that is a separate feature with its own setting, and shouldn't be a reinterpretation of this one. Two other things:
seerr/server/api/themoviedb/index.ts Lines 725 to 730 in 970bb54 That override is deliberate. Disabling the selector removes it. |
My ideia is to take advantage of the value already set for Discover Language since this option is to filter content by original language. The issue with this option is that users can still search for content for all languages no matter what this input states. For example, if I want my users to only be able to find content with Original Language [English, Japanese, Portuguese] currently there's no way to achieve that. My PR gives the ability to filter out results based on the Discover Language input value with the flexibility of choosing where this filter can be applied (preferably everywhere). I'll look into the pagination issue, that would intruduce a bug for sure. |

File changes review for the Filter by original language feature
Commented in CodeRabbit Change Stack
There was a problem hiding this comment.
I didn't do a thorough review but here are somethings I noticed while I skimmed through:
The MediaSlider fix looks right, but it’s the only place that actually got fixed. Every other scroll-driven view still takes isEmpty and isReachingEnd directly from useDiscover, which calculates them from the unfiltered titles:
seerr/src/hooks/useDiscover.ts
Lines 145 to 150 in 1efaf70
If page 1 returns 20 results and the filter removes all of them, isEmpty is still false, so the list renders nothing. fetchMore is also only triggered by onScrollBottom, but there’s nothing to scroll, so it never fires. It just gets stuck instead of fetching the next page.
That affects both Discover pages, both keyword pages, Upcoming, Trending, DiscoverTvUpcoming, and Search. Search also still uses titles?.length in its isLoading check.
MediaSlider itself still has the size < 5 cap too, so a narrow allowlist could leave a slider with three items and then stop fetching.
The slideover issue I mentioned earlier is also still unaddressed:
If Discover Language becomes an allowlist of [English, Japanese, Portuguese], the selector should be limited to those three rather than disabled. As it is now, a user who is allowed all three can’t narrow Discover down to just Japanese. So the restriction ends up removing the filtering it was supposed to preserve.
As for the overall goal, I still think this should be its own setting. The toggles can remain their own setting, but the language allowlist shouldn’t be tied to Discover Language.
Right now the hook just reads originalLanguage from public settings, so the allowlist effectively becomes Discover Language. That means you can’t have Japanese-only Discover rows while still allowing English, Japanese, and Portuguese elsewhere, such as Search.
That’s also why you had to disable the selector, since one value is effectively being used for two different purposes, so whatever you set for Discover gets interpreted as a restriction too. That also removes functionality for existing users who don’t care about this feature.
I’d give the allowlist its own languages field. That solves both issues, and you wouldn’t need the 13 flags either.
As it stands, this can’t be merged regardless of the rest. Anyone who upgrades with Discover Language already set will lose the language filter in the slideover without opting into any of these changes. That effectively removes existing functionality in the name of adding a new feature (in other words I consider this a regression).

Description
Prevents unwanted requests by allowing the owner to restrict discovery results to a specific original language.
The Original Language filter is disabled whenever Discover Language is set to a value other than an empty string, since the two filters should not be used together.
How Has This Been Tested?
Tested locally in the development environment.
pnpm build.Screenshots / Logs (if applicable)
The Original Language filter field on discovery pages is disabled if Discover Language has any other value than an empty string.
