我的问题是我只能从管理面板上传图片。每当我尝试上传时,通过我制作的表格,似乎图像都没有保存。

models.py

    from __future__ import unicode_literals
    from django.utils.encoding import python_2_unicode_compatible
    import uuid
    from django.db import models
    from django.conf import settings
    from django.core.urlresolvers import reverse

    import os
    import uuid

    YESNO_CHOICES = (
        (0, 'Ja'),
        (1, 'Nej')
        )


    SESSION_CHOICES = (
        (0, '1'),
        (1, '2'),
        (2, '3'),
        (3, '4'),
        (4, '5'),
        )

    def upload_to_location(instance, filename):
        blocks = filename.split('.')
        ext = blocks[-1]
        filename = "%s.%s" % (uuid.uuid4(), ext)
        instance.title = blocks[0]
        return os.path.join('uploads/', filename)
    # Create your models here.

    class Client(models.Model):
        fulde_navn = models.CharField('Navn', max_length=75)
        adresse = models.CharField(max_length=100)
        email = models.EmailField(null=True, blank=True)
        tidligere_klient = models.IntegerField(choices=YESNO_CHOICES, null=True, blank=True)
        foerste_session = models.DateField('Dato for 1. session', null=True, blank=True)
        beskrivelse = models.TextField('Noter', null=True, blank=True)
        arbejde = models.CharField('Arbejde', max_length=200)
        relateret_til_andre_klienter = models.IntegerField(choices=YESNO_CHOICES, null=True, blank=True)
        vurder_sidste_session = models.IntegerField(choices=SESSION_CHOICES, null=True, blank=True)
        profilbillede = models.ImageField('Profilbillede',
                                    upload_to='profile_pics/%Y-%m-%d/',
                                    null=True,
                                    blank=True)


        def __unicode__(self):
            return self.fulde_navn

        def get_absolute_url(self):
            return reverse(viewname="client_detail", args=[self.id])

这是 forms.py

from django import forms

from .models import Client

class ClientForm(forms.ModelForm):


    class Meta:
        model = Client
        fields = (
            'fulde_navn',
            'adresse',
            'email',
            'tidligere_klient',
            'foerste_session',
            'beskrivelse',
            'arbejde',
            'relateret_til_andre_klienter',
            'vurder_sidste_session',
            'profilbillede'
        )

最后,我的 settings.py 应该是相关的:

            join(BASE_DIR, 'templates'),
            # insert more TEMPLATE_DIRS here
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [

        },
    },
]

免责声明:我知道它不是最具吸引力的代码,但我是编程新手。遗憾!

从您的代码中,您编写了一个函数,用于为上传的文件生成新名称,但您没有使用它。 更改

profilbillede = models.ImageField('Profilbillede',
                                    upload_to='profile_pics/%Y-%m-%d/',
                                    null=True,
                                    blank=True)

profilbillede = models.ImageField('Profilbillede',
                                    upload_to=upload_to_location,
                                    null=True,
                                    blank=True)
