Django ModelForm Imagefield上傳

Question

我對Django來說很新，我遇到了使用ModelForm處理圖片上傳的問題。 我的模型如下：

class Project(models.Model): 
    name = models.CharField(max_length=100) 
    description = models.CharField(max_length=2000) 
    startDate = models.DateField(auto_now_add=True) 
    photo = models.ImageField(upload_to="projectimg/", null=True, blank=True) 

而且的ModelForm是如下：

class AddProjectForm(ModelForm): 
    class Meta: 
     model = Project 
     widgets = { 
      'description': Textarea(attrs={'cols': 80, 'rows': 50}), 
     } 
     fields = ['name', 'description', 'photo'] 

和視圖功能是：

def addProject(request, template_name): 
if request.method == 'POST': 
    addprojectform = AddProjectForm(request.POST,request.FILES) 
    print addprojectform 
    if addprojectform.is_valid(): 
     newproject = addprojectform.save(commit=False) 
     print newproject 
     print request.FILES 
     newproject.photo = request.FILES['photo'] 
     newproject.save() 
     print newproject.photo 
else: 
    addprojectform = AddProjectForm() 

newProposalNum = projectProposal.objects.filter(solved=False).count() 
return render(request, template_name, {'addprojectform':addprojectform, 
             'newProposalNum':newProposalNum}) 

模板是：

<form class="bs-example form-horizontal" method="post" action="">{% csrf_token %} 
         <h2>Project Name</h2><br> 
         {{ addprojectform.name }}<br> 
         <h2>Project Description</h2> 
         {{ addprojectform.description }}<br> 
         <h2>Image Upload</h2><br> 
         {{ addprojectform.photo }}<br> 
         <input type="submit" class="btn btn-success" value="Add Project"> 
        </form> 

Can any一個幫助我，或者你能舉一個圖像上傳的例子嗎？ 謝謝！

Answer 1

好的，謝謝大家。我發現自己犯了一個愚蠢的錯誤。 我應該在<form> 中加enctype="multipart/form-data"否則，它不會上傳文件。

您不應該將newproject.photo設置爲request.FILES['photo']（實際上，此處可能會破壞您的代碼）。只需保存addprojectform與addprojectform.save()而不是newproject = addprojectform.save(commit=False)。在這裏看到更多的信息：https://docs.djangoproject.com/en/1.5/topics/http/file-uploads/#handling-uploaded-files-with-a-model
