问题 I have a queryset in Django that calls Model.objects.values('item') ... where 'item' is a Foreign Key. class Words(models.Model): word = models.CharField() class Frequency(models.Model): word = models.ForeignKey(Words) ... So this returns the item id and displays as an id in the template. How do I show the actual item value in the template instead of the id? 回答1: To refer properties of Foreign Key items, you should use '__' lookup notation in fields. MyModel.objects.values('item__prop1',

问题 Is there any way to add template tags into javascript and css files? I would use it for anything from passing in urls to media url links (image paths, etc) to conditional javascript based on user permissions. I just had a thought that maybe I can serve it up as if it were a template but have the url as my javascript file. Is that the only way to do somethign like this? If so, it probably wouldn't work with my media generator, so I'd probably want a better solution if there was one out there.

问题 If you have 2 views, the first uses modelform that takes inputted information from the user (date of birth, name, phonenumber, etc), and the second uses this information to create a table. How would you pass the created object in the first view to the next view so you can use it in the second view's template I'd appreciate any help you can share 回答1: One approach is to put the object into a session in your first view, which you could then retrieve from the request.session in the second view.
