我目前正在构建一个Web应用程序，其中使用reportlab库从Django模型中生成了pdf数据，并将其下载为HttpResponse（content_type ='application / pdf'），并且该程序正常运行。现在它要从视图返回，我想将其上传到Django模型，而不是下载它。有可能请帮我解决有关我的“毕业设计”的问题吗？我将非常感谢您。
我目前正在使用Django最新更新和reportlab库来生成pdf。
下面是生成pdf并将其重新创建为HttpResponse的函数。
def format1(personal_info,education,skills,experience,statement,languages,user):
education_list = list()
skills_list = list()
experience_list = list()
for i in education:
temp_dict = dict()
temp_dict["degree"] = i.Degree
temp_dict["institute"] = i.Institute
temp_dict["city"] = i.City
temp_dict["grade"] = i.Grade
education_list.append(temp_dict)
for i in skills:
temp_dict = dict()
temp_dict["skill"] = i.Skill_Title
temp_dict["level"] = i.Level
temp_dict["description"] = i.Description
skills_list.append(temp_dict)
for i in experience:
temp_dict = dict()
temp_dict["job"] = i.Job_Title
temp_dict["organization"] = i.Organization
temp_dict["city"] = i.City
temp_dict["timeperiod"] = i.TimePeriod
experience_list.append(temp_dict)
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment;filename=' + user + ".pdf"
c = canvas.Canvas(response, pagesize=letter)
width,height = letter

下面是我的Django模型，我要在其中上传生成的pdf
class Application(models.Model):
job = models.ForeignKey(Posts,on_delete=models.CASCADE)
user = models.ForeignKey(User,on_delete=models.CASCADE)
status = models.BooleanField(default=False,blank=False)
cv = models.FileField(upload_to="pdf-files")
def __str__(self):
return self.job.organization.Name
下面是我尝试将生成的pdf上传到模型中的代码
response = format1(person,education,skills,experience,statement,langs,username)
file = ContentFile(response.content)
print(file) # output = Raw Content
obj = models.Application(user=user,job=job,cv=file)
obj.save()
我想将生成的pdf上传到该模型中，但是结果是运行该代码后该模型中的空白字段。
