/ 19 июня 2019

У меня есть мезонинный проект, и я пытаюсь обновить ключевые слова в записи блога. Я испытываю затруднения с получением правильного формата для вызова KeywordsField.save_form_data, это вызывает js, который обновит ключевые слова в сообщении в блоге. Смотрите ниже:

Из Messanine / generic / fields.py 

class KeywordsField(BaseGenericRelation):
    """
Stores the keywords as a single string into the
``KEYWORDS_FIELD_NAME_string`` field for convenient access when
searching.
"""

    default_related_model = "generic.AssignedKeyword"
    fields = {"%s_string": CharField(editable=False, blank=True,
                                 max_length=500)}

    def __init__(self, *args, **kwargs):
    """
    Mark the field as editable so that it can be specified in
    admin class fieldsets and pass validation, and also so that
    it shows up in the admin form.
    """
        super(KeywordsField, self).__init__(*args, **kwargs)
        self.editable = True

        def formfield(self, **kwargs):
    """
    Provide the custom form widget for the admin, since there
    isn't a form field mapped to ``GenericRelation`` model fields.
    """
        from mezzanine.generic.forms import KeywordsWidget
        kwargs["widget"] = KeywordsWidget
        return super(KeywordsField, self).formfield(**kwargs)


        def save_form_data(self, instance, data):
    """
    The ``KeywordsWidget`` field will return data as a string of
    comma separated IDs for the ``Keyword`` model - convert these
    into actual ``AssignedKeyword`` instances. Also delete
    ``Keyword`` instances if their last related ``AssignedKeyword``
    instance is being removed.
    """
        from mezzanine.generic.models import Keyword
        related_manager = getattr(instance, self.name)
        # Get a list of Keyword IDs being removed.
        old_ids = [str(a.keyword_id) for a in related_manager.all()]
        new_ids = data.split(",")
        removed_ids = set(old_ids) - set(new_ids)
        # Remove current AssignedKeyword instances.
        related_manager.all().delete()
        # Convert the data into AssignedKeyword instances.
        if data:
            data = [related_manager.create(keyword_id=i) for i in new_ids]
        # Remove keywords that are no longer assigned to anything.
        Keyword.objects.delete_unused(removed_ids)
        super(KeywordsField, self).save_form_data(instance, data)

Из моих Views.py 

class PubForm(forms.ModelForm):

   class Meta:
        model = BlogPost
        fields = ['keywords']


def UpdatePub(request, slug): 
    blog_post = BlogPost.objects.get(id=slug)
    if request.method == 'POST': 
        form = PubForm(request.POST)   
        if form.is_valid(): 
            publish_date = datetime.datetime.now()
            blog_post.status = CONTENT_STATUS_PUBLISHED             
            publish_date=publish_date
            tags=form.cleaned_data['keywords']
            blog_post.save() 
            KeywordsField.save_form_data(user,blog_post,tags)       
            return HttpResponseRedirect('/write/') 
    else:
        form = PubForm(instance=blog_post)
    return render(request, 'blog_my_pub.html', {'form' : form})

Он жалуется, что поле 'пользователь' не имеет атрибута 'имя'. Я пробовал много разных значений для этого параметра и не могу понять это. Любая помощь будет оценена.

Спасибо за любой вклад.
