Question

我正在尝试在Django中创建评论表单。我已经呈现了表单，但是我希望表单显示当前登录用户的名称，以使我能够将每个评论与用户相关联。

这是我的模特：

class Review(models.Model):
    company = models.ForeignKey(Company, null=True, on_delete=models.SET_NULL) 
    # SET_NULL ensures that when a company is deleted, their reviews remains
    reviewers_name = models.CharField(max_length=250, verbose_name='Reviewed By: (Your Name)')
    review_text = models.TextField(max_length=500, verbose_name='Your Review: (Maximum of 200 Words)')
    rating = Int_max.IntegerRangeField(min_value=1, max_value=5)
    date_added = models.DateField('Review Date', auto_now_add=True)

这是我的观点：

def submit_review(request):
    form = ReviewForm()
    if request.method == 'POST':
        form = ReviewForm(request.POST)
        if form.is_valid:
            form.save()
            # gets the company that was immediately submitted in the review form
            company = request.POST.get('company')
            
            # gets the rating that was immediately submitted in the review form
            rating = request.POST.get('rating')
            
            # uses the name of the company submitted to instantiate the company from the Company database
            companyone = Company.objects.get(pk=company)
            
            """
            emloys companyone above to retrieve already existing average rating associated with it
            adds this to the current rating sent by the user and stores the total back to the average 
            rating field of companyone
            """
            companyone.average_rating = round((int(rating) + int(companyone.average_rating))/2)
            companyone.save()
            
            return redirect('review-submitted')
    context = {
        'form': form
    }
    return render(request, 'submit-review.html', context)

以下是呈现的表单：

class ReviewForm(ModelForm):
    class Meta:
        model = Review
        fields = '__all__'

Answer 1

在模板中，

{% if user.is_authenticated %}
     <p>{{ user.get_username }} </p>
{% endif %}

在视图中，

request.user.get_username()

在模板中呈现
