The issue is in `django/urls/resolvers.py`. \n\nThe problem is in how Django's `ResolverMatch` or the URL resolver handles regex groups.

Let me reconsider.\n\nThe issue is that when you have `(?P<format>(html|json|xml))?`, the regex has TWO groups:\n1. The named group `format`\n2. The inner unnamed group `(html|json|xml)`\n\nWhen the URL matches, `match.groups()` returns BOTH captured values as a tuple, e.g., `('html', 'html')`.\n\nThe current code says: if there are named groups (kwargs), don't pass positional args. But `kwargs` could be `{}` if the optional group didn't match (i.e., the URL was `/module/`), in which case `match.groups()` returns `(None, None)` and both are passed as positional args.\n\nActually, looking at this more carefully - the fix should ensure that when we have kwargs, we don't also pass the groups as args. But there's another issue: when the optional group doesn't match, kwargs is empty `{}` because the dict comprehension filters out None values.\n\nLet me trace through:\n- URL `/module/html/` matches, `match.groupdict()` = `{'format': 'html'}`, `match.groups()` = `('html', 'html')`\n- With `args = () if kwargs else match.groups()`: kwargs is `{'format': 'html'}`, so args = `()`\n- After filtering: kwargs = `{'format': 'html'}`, args = `()` - This should work fine!\n\n- URL `/module/` matches, `match.groupdict()` = `{'format': None}`, `match.groups()` = `(None, None)`\n- With `args = () if kwargs else match.groups()`: kwargs is `{'format': None}`, so args = `()`\n- After filtering None: kwargs = `{}`, args = `()` - This should also work!\n\nHmm, let me re-read the issue. The error says \"3 were given\" meaning request + 2 extra arguments. That means both groups are being passed.\n\nThe issue must be that the check `if kwargs` is happening AFTER the groupdict, but the groupdict contains None values, so it's truthy even when the match has None. Wait no, `{'format': None}` is truthy.\n\nLet me look at this differently. The commit 76b993a117b61c41584e95149a67d8a1e9f49dd1 introduced the filtering of None values from kwargs. Before filtering, kwargs would be `{'format': None}` which is truthy. After the change, kwargs becomes `{}` which is falsy, so `args = match.groups()` gets executed, passing `(None, None)` as positional args.\n\nBut wait, that's also wrong because we'd get 2 extra args both being None.\n\nThe real issue is: the check for whether to use kwargs or args is done BEFORE the None filtering, but the filtering can make kwargs empty. And even when kwargs is non-empty, the nested group still contributes an extra positional group.\n\nThe fix should be: only pass positional args that are NOT part of any named group. Since `match.groups()` returns ALL groups including nested ones inside named groups, we need to filter those out.\n\nThe correct fix is to check if there are any named groups in the pattern, not whether kwargs currently has values:\n\n--- a/django/urls/resolvers.py\n+++ b/django/urls/resolvers.py\n@@ -152,7 +152,7 @@ class RegexPattern(CheckURLMixin):\n         match = self.regex.search(path)\n         if match:\n             kwargs = match.groupdict()\n-            args = () if kwargs else match.groups()\n+            args = () if self.regex.groupindex else match.groups()\n             kwargs = {k: v for k, v in kwargs.items() if v is not None}\n             return path[match.end():], args, kwargs\n         return None\n\nThis checks if the pattern has any named groups at all (`self.regex.groupindex` is a dict mapping group names to group numbers), rather than checking if the current match produced non-empty kwargs.",

JSONField values are displayed as Python dict repr (`{'foo': 'bar'}`) instead of valid JSON (`{\"foo\": \"bar\"}`)\n2. The fix should be in `django.contrib.admin.utils.display_for_field`\n3.

The issue is that when a model has a `UniqueConstraint`, the system doesn't validate that the fields referenced in the constraint actually exist on the model. The `unique_together` option does this validation via `_check_local_fields()` and raises `models.E012` if fields don't exist.\n\nThe fix needs to be in `django/db/models/base.py` in the `_check_constraints` method (or we need to add constraint field checking). Let me create the patch based on Django's structure:\n\nIn Django's `base.py`, there's a `_check_constraints` method that should call `_check_local_fields()` for `UniqueConstraint` fields. The `_check_local_fields()` method is already used by `_check_unique_together()` and `_check_index_together()`.\n\nHere's the patch:\n\n--- a/django/db/models/base.py\n+++ b/django/db/models/base.py\n@@ -1,5 +1,6 @@\n import copy\n import inspect\n+import itertools\n import warnings\n from functools import partialmethod\n from itertools import chain\n@@ -1955,9 +1956,21 @@ class Model(metaclass=ModelBase):\n     @classmethod\n     def _check_constraints(cls, databases):\n         errors = []\n+        for db in databases:\n+            if not router.allow_migrate_model(db, cls):\n+                continue\n+            connection = connections[db]\n+            if not (\n+                connection.features.supports_table_check_constraints or\n+                'supports_table_check_constraints' not in cls._meta.required_db_features\n+            ) and not (\n+                connection.features.supports_partial_indexes or\n+                'supports_partial_indexes' not in cls._meta.required_db_features\n+            ):\n+                continue\n         for constraint in cls._meta.constraints:\n-            errors.extend(constraint.check())\n-        for db in databases:\n+            if isinstance(constraint, UniqueConstraint):\n+                errors.extend(cls._check_local_fields(constraint.fields, 'constraints'))\n             if not router.allow_migrate_model(db, cls):\n                 continue\n             connection = connections[db]\n\nWait, I need to look at the actual structure more carefully.
