python - Django 'RequestContext' 未定义 - forms.ModelForm

Question

我在尝试加载我的表单时遇到请求上下文错误。

1. 在我的 models.py 上创建了 ModelForm
2. 在我的 View 中创建了 def add
3. 链接到 View 的 url

View .py

def add_company(request):
# Get the context from the request.
context = RequestContext(request)

# A HTTP POST?
if request.method == 'POST':
    form = CompanyForm(request.POST)

    # Have we been provided with a valid form?
    if form.is_valid():
        # Save the new category to the database.
        form.save(commit=True)

        # Now call the index() view.
        # The user will be shown the homepage.
        return index(request)
    else:
        # The supplied form contained errors - just print them to the terminal.
        print form.errors
else:
    # If the request was not a POST, display the form to enter details.
    form = CompanyForm()

# Bad form (or form details), no form supplied...
# Render the form with error messages (if any).
return render_to_response('add_company.html', {'form': form}, context)

但是它卡在了 View 的第一行。我做的和 rango 教程一样。它在那里工作。但是我的不工作。有人提示吗？

谢谢

明白了:

Problem wasn t on form - it was template import problem. Imported render_to_response instead of render solved it. Now it can goes on. ciao and tx

你实际上不需要担心传递 RequestContext，因为如果你使用 render() ，它会为您处理。

所以你会这样做:

return render(request, 'add_company.html', {'form': form})

代替

return render_to_response('add_company.html', {'form': form}, context)

就是这样。当然，您也需要导入它。

from django.shortcuts import render

希望，这能解决您的问题
