After some research: While you can extend sfValidatedFile and override generateFilename I found out that sfFormPropel checks for the existence of a method based on the column name for the model to name the file. From symfony/plugins/sfPropelPlugin/lib/form line 292: <pre><code>$method = sprintf('generate%sFilename', $column); if (null !== $filename) { return $file->save($filename); } else if (method_exists($this, $method)) { return $file->save($this->$method($file)); } </code></pre> Therefore, if your column is called file_name, the method looks for the existence of generateFileNameFilename in the form class. This way you only have to add one method to your form class, rather than extending the sfValidatedFile widget. For instance, my function uses the original name if it is not taken, otherwise appends a sequential number (one method is to recursively check the generated filename): <pre><code>public function generateFileNameFilename($file = null) { if (null === $file) { // use a random filename instead return null; } if (file_exists($file->getpath().$file->getOriginalName())) { return $this->appendToName($file); } return $file->getOriginalName(); } public function appendToName($file, $index = 0) { $newname = pathinfo($file->getOriginalName(), PATHINFO_FILENAME).$index.$file->getExtension(); if (file_exists($file->getpath().$newname)) { return $this->appendToName($file, ++$index); } else { return $newname; } } </code></pre> I can't find this documented in the symfony API anywhere which is why it took some searching the code base to find. If you are using this method in many places, extending sfValidatedFile might be a good option too.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
