Django недопустимый литерал для int () с save_m2m

0 голосов
/ 21 июня 2020

Я пытаюсь интегрировать vue теги input http://www.vue-tags-input.com/# / с моим проектом.

Автозаполнение работает нормально, форма тоже. Когда я сохраняю форму, все, кроме категории (тегов), сохраняется.

Я знаю, что с отношениями многие ко многим я должен использовать save_m2m в поле зрения, но когда я это делаю, появляется ошибка: 

      invalid literal for int() with base 10: 'e'

Мое представление: 

@login_required
def save_embed(request):
interests = RecipeCategory.objects.all()

if request.method == "POST":
    form = AddEmbed(request.POST)
    if form.is_valid():
        new_embed = form.save(commit=False)
        new_embed.added_by = request.user
        new_embed.save()
        form.save_m2m()
else:
    form = AddEmbed()

return render(request, 'embed/embedadd.html', {'form': form,
                                              'interests': interests})

Модель: 

class Embed(models.Model, Activity):
url = models.URLField(max_length=255, verbose_name='Adres przepisu')
title = models.CharField(max_length=255, verbose_name='Tytuł')
description = models.TextField(verbose_name='Opis', blank=True, null=True)
type = models.CharField(blank=True, max_length=200)
thumbnail_url = models.URLField(max_length=255, blank=True, null=True)
image = models.ImageField(upload_to='recipes', blank=True)
html = models.TextField()
votes = GenericRelation(LikeDislike, related_query_name='embedlikes')
added_by = models.ForeignKey(User, on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
category = TreeManyToManyField(RecipeCategory, blank=True, null=True, related_name='embeds', verbose_name='Kategoria')
slug = AutoSlugField(populate_from='title', unique=True)

Редактировать - Форма 

class AddEmbed(ModelForm):

    url = forms.URLField(label='Adres przepisu', widget=forms.URLInput(attrs={'v-model': 'embed.url', '@paste':'paste', '@input':'input'}))
    title = forms.CharField(widget=forms.HiddenInput(attrs={':value':'embedsinfo.title'}))
    description = forms.CharField(widget=forms.HiddenInput(attrs={':value':'embedsinfo.description'}))
    thumbnail_url = forms.CharField(widget=forms.HiddenInput(attrs={':value':'embedsinfo.thumbnail_url'}))
    html = forms.CharField(widget=forms.HiddenInput(attrs={':value':'embedsinfo.html'}))
    category = forms.CharField(widget=forms.HiddenInput(attrs={':value': 'tags'}))

    class Meta:
        model = Embed
        fields = ['url','title', 'description', 'thumbnail_url', 'html', 'category']
