Original Traceback (most recent call last): File "../django/django/template/debug.py", line 71, in render_node result = node.render(context) File "../django/django/template/defaulttags.py", line 148, in render nodelist.append(node.render(context)) File "../django/django/template/debug.py", line 87, in render output = force_unicode(self.filter_expression.resolve(context)) File "../django/django/template/__init__.py", line 518, in resolve obj = self.var.resolve(context) File "../django/django/template/__init__.py", line 659, in resolve value = self._resolve_lookup(context) File "../django/django/template/__init__.py", line 688, in _resolve_lookup current = getattr(current, bit) File "/arquivos/Trabalhos/WN/Cranes/cranes_com/apps/spares/models.py", line 108, in __getattr__ thumbnail = get_image_thumbnail_filename() File "/arquivos/Trabalhos/WN/Cranes/cranes_com/apps/spares/models.py", line 100, in get_image_thumbnail_filename file, ext = os.path.splitext(self.image.path) File "../django/django/db/models/fields/files.py", line 50, in _get_path self._require_file() File "../django/django/db/models/fields/files.py", line 40, in _require_file raise ValueError("The '%s' attribute has no file associated with it." % self.field.name) ValueError: The 'image' attribute has no file associated with it. }}} This is VERY confuse and make developer spent some time to find the error message and the file/line where the error occured. My suggestion is change the H2 tag to PRE, with some CSS changes, so, the line breaks are respected exactly as they are when Python raises the exception. | nobody | marinho | 0 | 1 | 0 | 0 | 0 | 0 |
