在这个webapp中,我有一个问题模型和一个问题图模型。每当用户上传图像时,它都应该保存在media/question\u image文件夹中。
如果我从管理面板上传的话,效果很好,但是当我从网页上传图片时,它不会被保存。事实上,post请求是有效的,我没有得到任何类型的错误。图像未保存到所需位置。
class QuestionDiagram(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE, related_name='questionDiagrams')
user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True)
question_diagram = models.ImageField(upload_to='question_diagram/')
question_diagram_text = models.CharField(max_length = 48)
date = models.DateTimeField(auto_now_add=True, blank=True, null=True)
表单.py

class Meta:
model = QuestionDiagram
fields = ['question_diagram', 'question_diagram_text']
设置.py
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
在项目中网址.py(添加了mediaroot和mediaurl)
