Django從models.py調用數據並顯示它

我試圖展示我在model.py中的postlogin.html頁面上有什麼，但即使數據庫中有數據，頁面也不會顯示任何內容。我覺得我無法通過views.py中的部分（posts = NewRecipePost.objects.all（）。order_by（「 - post_date」））調用數據。下面的代碼只是代碼的一部分，一切都正確導入並正確縮進。Django從models.py調用數據並顯示它

我很感謝您的建議。感謝

models.py

from django.db import models 
class NewRecipePost(models.Model): 
    title = models.CharField('title', blank=False, max_length=50) 
    post_date = models.DateField(auto_now_add=True) 
    ingredients = models.TextField('ingredients', max_length=1000) 
    content = models.TextField('content', max_length=1000) 

    def __unicode__(self): 
     return self.title

forms.py

from recipeapp.models import NewRecipePost 

class NewRecipeForm(forms.ModelForm): 

    class Meta: 
     model = NewRecipePost

views.py

DEF my_view（請求，用戶名）：

posts = NewRecipePost.objects.all().order_by("-post_date") 

if request.method == 'POST': 
    form = NewRecipeForm(request.POST) 
    if form.is_valid(): 
     form.save() 
else: 
    form = NewRecipeForm() 
variables = RequestContext(request, {'form':form,'username':username, 'posts':posts}) 

return render_to_response('postlogin.html',variables)

postlogin.html

  <ul> 
       {% for post in posts.object_list %} 
        <div>{{post.title}}</div> 
        <div>{{post.post_date}}</div> 
        <ul> 
         <div>{{post.ingredients}}</div> 
         <div>{{post.content}}</div> 
        </ul> 
       {% endfor %} 

      </ul>
