阅读更多关于 Django - MEDIA_ROOT and MEDIA_URL

问题 Could you please suggest me the good documentation where I can understand the MEDIA_URL and MEDIA_ROOT?

阅读更多关于 How do I jQuery ajax live search for the models in Django?

问题 I tried live search with jquery and ajax, and even posted a question regarding this here, but there seems to have some serious problem somewhere in my view or in the ajax script I wrote. It searches and loads the content correctly. But if I backspace and there's no value in the search form, it still shows me a list of value that I entered the first time. I think there's really a big problem in my code. models.py: class Status(models.Model): status = models.TextField() image = models
