我想显示用户圆圈图标，我已经下载了一个字体很棒的 css 文件，版本为 4.7.0。但这对我不起作用。如果我使用 cdn 那么它的工作。我不明白下载的文件有什么问题。这是我的代码：
<html>
<head>
<link href="font-awesome.min.css" rel="stylesheet" type="text/css">
</head>
<body>
<i class="fa fa-user-circle-o"></i>
</body>
</html>
有谁知道是什么问题？
我正在编写单元测试用例.我创建一个文件对象并读取它,但我收到以下错误:
<<:'str'和'int'不受支持的操作数类型
方法:
def uploadExamineeDetails(request, exam_id):
try:
upload_file = request.FILES['upload-file']
except Exception:
return [_('Uploaded file is required.')]
try:
exam = get_object_or_404_from_admin(CourseExam, request, exam_id)
book = xlrd.open_workbook(file_contents=upload_file.read())
# further code
我的测试代码:
def test_uploadExamineeDetails(self):
self.examinee_result = os.path.join(os.path.dirname(settings.BASE_DIR),\
'var/sample_files_for_testing/examinees_result_upload.xls')
file = File(open(self.file, errors='ignore'))
uploaded_file = InMemoryUploadedFile(file=file, field_name='upload-file', name='examinee_result.xls',
content_type = 'application/vnd.ms-excel', size = file.size, charset = None)
self.request.FILES['upload-file'] = uploaded_file
xlrd.open_workbook(file_contents=uploaded_file.read())
response = uploadExamineeDetails(self.request, 1)
assert isinstance(response, tuple), 'should upload the examinee details'
excel文件中的数据:
[{'Enrollment Number': '', 'Username': 'exam_course_manager',
'row_num': 1, 'Obtained Score': …以下是我的模型：
class MyModel(models.Model):
code = models.CharField(_('Code'), max_length=56, null=False,
blank=False, db_column='code')
name = models.CharField(_('Name'), max_length=128, null=False,
db_index=True, db_column='name', blank=False)
created_at = models.DateTimeField(_('Created At'), null=False,
db_column='created_at', blank=False,
auto_now_add=True)
形成：
class MyForm(forms.Form):
class Meta:
model = MyModel
fields = '__all__'
视图
class MyView(View):
def get(self, request):
form = MyForm(request=request)
return render(request, 'test_manager/testrule_form.html', {'form': form})
显示此表单时，我可以看到除created_at之外的所有字段。有谁知道在更新某些对象时如何获取created_at字段？
