class VideoModel(models.Model):
title = models.CharField(max_length=200)
post_by = models.OneToOneField(settings.AUTH_USER_MODEL)

 This is a way of doing it. If you use a ModelForm, then it will show the
error message automatically. You can add some javascript for showing only
the one that was chosen. You should have for convenience a function or
method that return the url for the video independently of the source.

Let users either upload a file or provide an URL to a file

2018-01-17 Thread Tony 
 

I would like to let users either upload a video file(to AWS S3) or provide 
an URL to a video, e.g. Youtube/Vimeo.


I found a similar question for Rails: Rails: upload a file OR store a url 





But how do I do that in Django(1.11)?


Should I create 2 separate models, or model inheritance with abstract 
model, let users choose what they want to do in the frontend, then display 
the appropriate form?

class VideoModel(models.Model):
title = models.CharField(max_length=200)
post_by = models.OneToOneField(settings.AUTH_USER_MODEL)
created = models.DateTimeField(auto_now_add=True)
modified = models.DateTimeField(auto_now=True)

class Meta:
abstract = True
class VideoFile(VideoModel):
video = models.FileField(upload_to='uploads/')
class Videolink(VideoModel):
URL = URLField(max_length=200)

Would it be better if there is only 1 model with both a FileField and 
URLField. They are both set to blank = true. Put a message on the page, 
saying either upload a file or provide a Youtube link. In the backend, 
check the request.POST whether one of these fields is filled in, if not, 
render the form again with an error message.


Which one is better to handle such situation? Or they are equally horrible? 
I couldn't think of a third option.
