I have a ImageField that stores in AWS S3 (similar to FileField). In the form, it has this "Currently" label that shows the image file path. I would like to trim and just show the filename. referring to the latest answer in Django : customizing FileField value while editing a model , I still cant get it to work. It shows "Currently" with the file path name like this: https://imgur.com/a/xkUZi form.py class CustomClearableFileInput(ClearableFileInput): def get_template_substitution_values(self, value): """ Return value-related substitutions. """ logging.debug("CustomClearableFileInput %s",value

I've got a model like this: class Talk(BaseModel): title = models.CharField(max_length=200) mp3 = models.FileField(upload_to = u'talks/', max_length=200) seconds = models.IntegerField(blank = True, null = True) I want to validate before saving that the uploaded file is an MP3, like this: def is_mp3(path_to_file): from mutagen.mp3 import MP3 audio = MP3(path_to_file) return not audio.info.sketchy Once I'm sure I've got an MP3, I want to save the length of the talk in the seconds attribute, like this: audio = MP3(path_to_file) self.seconds = audio.info.length The problem is, before saving, the

I've got a field in my model of type FileField . This gives me an object of type File , which has the following method: File.name : The name of the file including the relative path from MEDIA_ROOT . What I want is something like " .filename " that will only give me the filename and not the path as well, something like: {% for download in downloads %} <div class="download"> <div class="title">{{download.file.filename}}</div> </div> {% endfor %} Which would give something like myfile.jpg In your model definition: import os class File(models.Model): file = models.FileField() ... def filename(self

I'm experimenting with a site that will allow users to upload audio files. I've read every doc that I can get my hands on but can't find much about validating files . Total newb here (never done any file validation of any kind before) and trying to figure this out. Can someone hold my hand and tell me what I need to know? As always, thank you in advance. You want to validate the file before it gets written to disk. When you upload a file, the form gets validated then the uploaded file gets passed to a handler/method that deals with the actual writing to the disk on your server. So in between

I have a model with a FileField , which holds user uploaded files. Since I want to save space, I would like to avoid duplicates. What I'd like to achieve: Calculate the uploaded files md5 checksum Store the file with the file name based on its md5sum If a file with that name is already there (the new file's a duplicate ), discard the uploaded file and use the existing file instead 1 and 2 is already working, but how would I forget about an uploaded duplicate and use the existing file instead? Note that I'd like to keep the existing file and not overwrite it (mainly to keep the modified time

My goal is to limit a FileField on a Django ModelForm to PDFs and Word Documents. The answers I have googled all deal with creating a separate file handler, but I am not sure how to do so in the context of a ModelForm. Is there a setting in settings.py I may use to limit upload file types? I handle this by using a clean_[your_field] method on a ModelForm. You could set a list of acceptable file extensions in settings.py to check against in your clean method, but there's nothing built-into settings.py to limit upload types. Django-Filebrowser, for example, takes the approach of creating a list
