Django-允许同时上传图像和文本吗？

Question

我想在我的 models.py 和 forms.py 中有一个字段，以便可以选择上传照片或文本，或同时上传两者。目前，我使用所见即所得的编辑器来做到这一点。我将如何修改我的模型以便我可以拥有该选项？到目前为止，这是我的代码：

models.py

class Problem(models.Model):
    slug = models.SlugField(null = False, unique = True, max_length = 255)
    topic = models.ForeignKey(Topic, on_delete = models.CASCADE)
    free = models.CharField(max_length = 1, choices = Free)

    #problem when introducing UUID field
    traceID = models.UUIDField(default=uuid.uuid4, editable = True)

    #use meta tags to optimize SEO
    metaTags = models.TextField(default = "")

    questionToProblem = models.TextField()

    #migration with CKEDitor is 0023_alter_problem_solutiontoproblem.py
    solutionToProblem = RichTextUploadingField(blank = True, null = True)

字段 solutiontoProblem 是我的文本编辑器所在的位置 - 我想要该字段以便它接受文本和图像。同样，这是我的 forms.py:

forms.py

class ProblemForm(forms.ModelForm):
    slug = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'link'}))
    topic = forms.ModelChoiceField(label = "Topic", queryset = Topic.objects.all())
    metaTags = forms.CharField(label = "Meta Tags", widget=forms.Textarea(attrs={"rows" : 15, "cols" : 90}))
    questionToProblem = forms.CharField(label = "Question", widget = QuestionFormWithPreview(attrs={'id' : 'mathInputForQuestion', 'cols': 90, 'rows': 15, 'onkeyup':'PreviewQuestion.Update()'}))
    solutionToProblem = forms.CharField(widget = CKEditorUploadingWidget(), label = "Solution")

    class Meta:
        model = Problem
        fields = ('metaTags', 'questionToProblem', 'solutionToProblem')

我如何获得它，以便模型和表单中的字段都可以接受图像文件或文本，或两者？

Answer 1

您可以将这两个字段放在其他模型中并从您的模型中指向它：

class Solution(models.Model):
    description = models.TextField(null=True, blank=True)
    image = models.ImageField(null=True, blank=True)

    def clean(self):
        if self.decription is None and self.image is None:
            raise ValidationError('Please provide image of text')
        super().clean()


class Problem(forms.Model):
    ...
    solutionToProblem = models.ForeignKey(Solution, on_delete=models.CASCADE)

然后您为 Solution 创建一个表单。可能就这么简单：

class SolutionForm(forms.ModelForm):
    class Meta:
        model = Solution
        fields = ('description', 'image')

因此，从问题模型的角度来看，这在技术上将是 一个字段，但具有两个属性。以及如何 represent/handle 你可以在你的前端决定（例如，当没有文本时只显示图像等）
