Bug: get_template_substitution_values() returns None, causing TypeError when substitutions.update(None) is called.
Severity: CRITICAL | Confidence: High
🔍 Detailed Analysis
When self.is_initial(value) is true, the code attempts to call substitutions.update(self.get_template_substitution_values(value)). However, get_template_substitution_values() is commented out and returns None. This leads to a TypeError: 'NoneType' object is not iterable, causing a server crash when rendering forms with existing files.
💡 Suggested Fix
Uncomment and implement get_template_substitution_values() to return a dictionary with initial and initial_url keys, ensuring substitutions.update() receives a valid iterable.

Potential issue: When `self.is_initial(value)` is true, the code attempts to call
`substitutions.update(self.get_template_substitution_values(value))`. However,
`get_template_substitution_values()` is commented out and returns `None`. This leads to
a `TypeError: 'NoneType' object is not iterable`, causing a server crash when rendering
forms with existing files.

Bug: FILE_INPUT_CONTRADICTION is used without import, causing NameError when contradictory file input occurs.
Severity: CRITICAL | Confidence: High
🔍 Detailed Analysis
The constant FILE_INPUT_CONTRADICTION is referenced in value_from_datadict() methods (e.g., line 373) without being imported. When a user attempts to upload a new file and simultaneously checks the 'clear' checkbox, this code path is executed, resulting in a NameError: name 'FILE_INPUT_CONTRADICTION' is not defined, which crashes the application.
💡 Suggested Fix
Import FILE_INPUT_CONTRADICTION from django.forms.fields or django.forms.widgets to resolve the NameError.
