Question

article = get_object_or_404(Article,slug=slug) 
categories = article.category.all() 

使用render_to_response()，如何在視圖中使用類別？

Answer 1

假設你已經在模板中的文章，你可以做到以下幾點：

# In your view 
return render_to_response('page.html', {'article': article}) 

# In your template 
{% for category in article.category.all %} 
    {{ category.attribute }} 
{% endfor %} 

# Or, if you already have the categories 
return render_to_response('page.html', {'categories': categories}) 
{% for category in categories %} 
    {{ category.attribute }} 
{% endfor %}
