如何通過gdata.youtube Python庫上傳YouTube視頻在Django

Question

我有一個Python/Django的動力應用程序，它有一個特點，我可以通過使用gdata.youtube Python庫

我引用發佈到YouTube視頻如下所示：https://developers.google.com/youtube/1.0/developers_guide_python

前開發人員遵循此非常有用的頁面中的說明，例如履行要求和驗證以上傳視頻。但它不起作用。 當我運行螢火蟲時，有一個500內部服務器錯誤，它跟蹤我的視圖中的upload_prepare 函數，這很可能在保存部分。

def upload_prepare(request): 
     if request.POST: 
      form = UploadForm(request.user, request.POST) 
      if form.is_valid(): 
       #error is in the next line 
       video = form.save() 

他也跟着如何通過Browserupload發佈YouTube視頻的說明

我的代碼如下：

models.py

class Category(models.Model): 
     text = models.CharField(max_length=100) 
     label = models.CharField(max_length=100) 
     scheme = models.URLField() 

     def toGData(self): 
      return gdata.media.Category(
       text=self.text, 
       label=self.label, 
       scheme=self.scheme) 

    class YoutubeUser(models.Model): 
     username = models.CharField(max_length=50) 
     ... 

     #Initialize gdata.youtube.service.YouTubeService object 
     def yt_service(self): 
      try: 
       return selt._yt_service 
      except AttributeError: 
     #setting up developer key and client ID 
       yt_service = gdata.youtube.service.YouTubeService() 
       yt_service.developer_key = settings.SYNCR_YT_DEVKEY 
       yt_service.client_id = 'LOLtest' 
     #setting up a authentication token 
       if self.token: 
        yt_service.SetAuthSubToken(self.token) 
       self._yt_service = yt_service 
       return yt_service 

     #Setting up AuthSub authentication for web apps 
     def authsub_url(self, request): 
     #urls.py url 
      base = reverse('authlanding', args=(self.id,)) 
      next = 'http://%s%s?next=%s' % (request.get_host(), base, urllib2.quote(request.build_absolute_uri())) 
      scope = 'http://gdata.youtube.com' 
      secure = False 
      session = True 

      return self.yt_service.GenerateAuthSubUrl(next, scope, secure, session) 

     #upgrade to a session token 
     def upgrade_to_session(self): 
      yt_service = self.yt_service 
      yt_service.SetAuthSubToken(self.token) 
      yt_service.UpgradeToSessionToken() 
      self.token = yt_service.current_token.get_token_string() 
      self.save() 

到目前爲止，那些在代碼在我的models.py中，這裏是我的forms.py中的代碼，導致錯誤的保存函數在這裏找到（請看上面的upload_prepare視圖）

forms.py

class UploadForm(forms.Form): 
     video_title = forms.CharField(max_length=100) 
     ... 
     #https://developers.google.com/youtube/1.0/developers_guide_python#UploadingVideos 
     #Browser-based upload 
     def save(self): 
      mediagroup = gdata.media.Group(
       title=gdata.media.Title(text=self.cleaned_data['video_title']), 
       description=gdata.media.Description(description_type="plain", text=self.cleaned_data['video_description']), 
       keywords=gdata.media.Keywords(text=self.cleaned_data['tags']), 
     #category already in GData format look in models.py 
       category=self.cleaned_data['category'].toGData(), 
       player=None, 
      ) 
      video_entry = gdata.youtube.YouTubeVideoEntry(media=mediagroup) 
      response = self.yt_user.yt_service.GetFormUploadToken(video_entry) 
      post_url = response[0] 
      youtube_token = response[1] 

      video = Video.objects.create(
       author=self.yt_user, 
       post_url=post_url, 
       youtube_token=youtube_token, 
       title=self.cleaned_data['video_title'], 
       description=self.cleaned_data['video_description'], 
       tag_list=self.cleaned_data['tags'], 
      ) 
      self.video = video 
      return video 

在html用來傳遞在另一方面，數據的形式結合Django表單，django的自定義標籤和AJAX

forms.py

class UploadForm(forms.Form): 
     video_title = forms.CharField(max_length=100) 
     video_description = forms.CharField(widget=forms.Textarea(attrs={'cols': 60, 
              'rows': 10})) 
     category = forms.ModelChoiceField(Category.objects, empty_label=None) 
     tags  = TagField(
       label=_('tags (comma separated)'), 
       required=True, 
       ) 

youtube_tags.py

def youtube_upload_form(context): 
    #UploadForm from above 
     upload_form = UploadForm(context['user']) 
     context['upload_form'] = upload_form 
     return context 

    register.inclusion_tag('syncr/youtube/upload.html', 
        takes_context=True)(youtube_upload_form) 

add_po st.html

<script> 
     function upload_video_to_youtube(url){ 
      action = "%s?nexturl=%s" % (youtube_url, url) 
      var new_form = create_element('form', {'method': 'post', 'action': action, 'enctype':"multipart/form-data"}); 
      $('#youtube_upload_form input').each(function(){ 
       var obj = this.cloneNode(true); 
       new_form.appendChild(obj); 
      }); 
      document.body.appendChild(new_form); 
      new_form.submit(); 
     } 
    </script> 

    {% block body %} 
    ... 
    <div id="rd2-radioOptionContent" class="hide radioOptionContent"> 
    {% youtube_upload_form %} 
    </div> 
    {% endblock %} 

希望大家得到我張貼的代碼的完美圖片。如果閱讀清楚，大多數的指示張貼在隨後的參考資料上（雖然用於提交數據的表格略有不同），並且由於我有500內部服務器錯誤，我需要在這些代碼行中找到問題。任何答案都非常感謝。

在你的yt_service方法的第二行中有一個錯字，應該是自我選擇。也許這就是問題所在？
