I am using the django-autoslug package with a project and, though the documentation is simple enough, I cannot get it to populate the database field with the slug.

models.py

```
class Thread(models.Model):
    forum = models.ForeignKey(Forum)
    title = models.CharField(max_length=100)
    date_created = models.DateTimeField('date created')
    user = models.ForeignKey(User)
    slug = AutoSlugField(populate_from='title')

```

I have also tried overriding the save() method with both an `AutoSlugField` and a regular `SlugField`, but this did not work either.

```
 def save(self, *args, **kwargs):
     self.slug = slugify(self.title)
     super(Thread, self).save(*args, **kwargs)

```

For example, when I create a thread with the title "This should create a slug", I would expect the "slug" field in the database to be populated with "this-should-create-a-slug". Instead, it is only being populate with an empty string: ''

Does anyone know what might cause this? I have not been able to find documentation of any similar issues with either the django-autoslug package or just overriding the save() method with a regular `SlugField`

File file[] = Environment.getExternalStorageDirectory().listFiles();
    recursiveFileFind(file);

public void recursiveFileFind(File[] file1){
int i = 0;
String filePath="";
     if(file1!=null){
    while(i!=file1.length){
        filePath = file1[i].getAbsolutePath();
            if(file1[i].isDirectory()){
                    File file[] = file1[i].listFiles();
            recursiveFileFind(file);
            }
        i++;
        //Log.d(i+"", filePath);
    }
  }
}

private void getAllFilesOfDir(File directory) {
    Log.d(TAG, "Directory: " + directory.getAbsolutePath() + "\n");

    final File[] files = directory.listFiles();

    if ( files != null ) {
        for ( File file : files ) {
            if ( file != null ) {
                if ( file.isDirectory() ) {  // it is a folder...
                    getAllFilesOfDir(file);
                }
                else {  // it is a file...
                    Log.d(TAG, "File: " + file.getAbsolutePath() + "\n");
                }
            }
        }
    }
}

```
This code will give internal files.

```
    String[] SavedFiles;
    ArrayList<String> arrList;
    SavedFiles = getApplicationContext().fileList();

   arrList = new ArrayList<String>();
   if(SavedFiles != null)
          {
              for(int i=0; i<SavedFiles.length; i++)
              {
                  arrList.add(SavedFiles[i]);
              }

          }

```
