Lade Bild mit Django

Question

Aus irgendeinem Grund kann ich meine Bilder nicht mit Django hochladen. Die Modelle speichern den Dateinamen, speichern die Datei jedoch in meinem Medienordner.

Das ist mein Modell

class Quiz(models.Model): 
    name = models.CharField(
     verbose_name ='Quiz Title', 
     max_length  = 50 
     ) 
    description = models.TextField(
     blank   = True, 
     null   = True, 
     verbose_name = 'Quiz Description' 
     ) 
    pool = models.ForeignKey (
     Pool, 
     verbose_name = 'Category of Quiz', 
    ) 
    categories = models.ManyToManyField (
     Category, 
     through   = 'QuizCategory', 
     related_name = 'category', 
     verbose_name = 'Category', 
     help_text  = 'Categories in this Quiz' 
    ) 
    live = models.BooleanField (
     verbose_name = 'Quiz is Live?', 
     default   = False, 
    ) 
    logo = models.ImageField(
     upload_to  = 'logos', 
     blank   = True, 
     ) 
    def __unicode__(self): 
     return u'%s' % (self.name) 

Das ist mein GEÄNDERT istAnsicht

def create_quiz(request): 
    if request.method == "POST": 
     form = QuizForm(request.POST, request.FILES) 
     if form.is_valid(): 
      # file is saved 
      form.save() 

EDIT

Und das ist FORM Erklärung

class QuizForm (forms.ModelForm): 
    class Meta: 
     model = Quiz 
     fields = ('name', 'description', 'pool', 'categories', 'live', 'logo') 

HTML

 <form method="post" action="{% url 'create-quiz' %}" enctype="multipart/form-data" >{% csrf_token %} 
      <input hidden name="id" value="{% if quiz.id %}{{quiz.id}}{% else %}0{% endif %}" readonly> 
      <div class="col-xs-12 col-sm-8 col-md-6 col-md-offset-2"> 
       <input required type="text" name="name" {% if quiz.name %}value="{{quiz.name}}"{% else %}placeholder="Quiz Name"{% endif %} class="form-control quiz-search-box"> 
       <textarea required name="description" {% if quiz.description %}{% else %}placeholder="Quiz Description"{% endif %} class="form-control quiz-search-box">{% if quiz.description %}{{quiz.description}}{% endif %}</textarea> 
       <select name="pool" class="form-control quiz-search-box"> 
        {% for p in pool %}<option value="{{p.name}}" {% if quiz.pool.name == p.name %}selected{% endif %}>{{p.name}}</option>{% endfor %} 
       </select> 

       <h2>Questions</h2> 
       <table class="table table-condenced"> 
        {% for q in questions %} 
         <tr><td>{{q.name}}</td></tr> 
        {% endfor %} 
        {% if quiz != 'new' %} 
         <a data-toggle='modal' data-target='#myQuestionModal' class="btn btn-primary">Add Question</a> 
        {% endif %} 
       </table> 
      </div> 
      <div class="col-xs-12 col-sm-4 col-md-2 "> 
       <span class="number-of-questions"> 
        Number of questions in this quiz: {{questions|length}} 
       </span> 
       <span class="add-quiz-logo"> 
        {% if quiz.logo %} 
         <img id="logo" src="/media/{{quiz.logo}}" width="150" alt="Logo spacer" /> 
        {% else %} 
         <img id="logo" src="{% static '/img/no-logo.png' %}" width="150" alt="Logo spacer" /> 
        {% endif %} 
        <input id="id_image" type="file" class="" name="logo" onchange="readURL(this);"> 
       </span> 
       <div> 
        <input type="submit" value="Save Quiz" class="btn btn-primary" />     
       </div> 
      </div> 
     </form> 

Hilfe sehr willkommen. Danke

Answer 1

Dr Maus löste dies. Ich habe vergessen enctype="multipart/form-data" in der <form>

Answer 2

Statt POST:

quiz.pool = Pool.objects.get(name=request.POST.get('pool')) 

versuchen, Dateien zu verwenden:

quiz.pool = Pool.objects.get(name=request.FILES.get('pool')) 

UPDATE:

Auch sollten Sie django einzurichten mit Mediendateien zu arbeiten. In zu Einstellungen:

MEDIA_URL = '/media/' 
MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'media') 

und umfassen Medien urlPattern:

if settings.DEBUG: 
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) 

Danach können Sie Bild in Ihre Vorlage mit diesem ein:

<img src="{{ instance.logo.url }}"/>
