Django "view didn' t 返回一个 HttpResponse 对象。”

Question

当我打电话时 运行删除 ，那么它会调用run，那么为什么“ View 没有返回一个HttpResponse对象”发生呢？

谢谢:)

View .py

def run(request, build):
    run_list = []   
    target_dict = {}
    target_num = 0
    build_id = 0
    all_run_list = TestRun.objects.all().order_by('id')
    for run in all_run_list:
        build_version = run.build.version
        build_number = run.build.number
        run_build = build_version + '.' + build_number
        if (build==run_build):
            run_list.append(run)
    return render_to_response('run.html', {'run_list': run_list})

def runDelete(request):
    run_list = request.POST.getlist('var_delete')
    build_id = request.POST.get('build_id')
    for run2 in run_list:
        run2 = int(run2)
    build_id = int(build_id)
    build_obj = Build.objects.get(id=build_id)
    build_version = build_obj.version
    build_number = build_obj.number
    build = build_version + '.' + build_number
    run(request, build)

Django View 有望返回 HttpResponse对象。您的观点确实调用 run但它不返回任何内容(请记住，在没有明确返回其他内容的语句的情况下，Python 函数返回 None)。所以改变这一行:

run(request, build)

到:

return run(request, build)

当然，这只适用于 run返回 HttpResponse实例。
