Django“RequestContext”未定义-forms.ModelForm

Question

我在尝试加载表单时遇到请求上下文错误。

1. 在my models.py上创建了ModelForm
2. 已在我的视图上创建def加载项
3. 链接到视图的url

视图.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)

但是它被卡在了第一行。我做的和兰戈教程一样。好的。但我的不起作用。有什么线索吗？

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

Answer 1

您忘记导入RequestContext了吗？

from django.template import RequestContext

Answer 2

实际上，您不必担心传递RequestContext，因为如果您使用render()，它会为您处理它。

所以你应该：

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

而不是

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

就这样。当然，你也需要导入它。

from django.shortcuts import render

希望这能解决你的问题
