flask-admin fileadmin 上传文件，中文名的解决方案 重写部分secure_filename

class upload_view(FileAdmin):
def _save_form_files(self, directory, path, form):
super()
filename = self._separator.join([directory, form.upload.data.filename])

if self.storage.path_exists(filename):
secure_name = self._separator.join([path, form.upload.data.filename])
raise Exception(gettext('File "%(name)s" already exists.',
name=secure_name))
else:
self.save_file(filename, form.upload.data)
self.on_file_upload(directory, path, filename)

@expose('/rename/', methods=('GET', 'POST'))
def rename(self):
"""
Rename view method
"""
form = self.name_form()

path = form.path.data
if path:
base_path, full_path, path = self._normalize_path(path)

return_url = self._get_dir_url('.index_view', op.dirname(path))
else:
return redirect(self.get_url('.index_view'))

if not self.can_rename:
flash(gettext('Renaming is disabled.'), 'error')
return redirect(return_url)

if not self.is_accessible_path(path):
flash(gettext('Permission denied.'), 'error')
return redirect(self._get_dir_url('.index_view'))

if not self.storage.path_exists(full_path):
flash(gettext('Path does not exist.'), 'error')
return redirect(return_url)

if self.validate_form(form):
try:
dir_base = op.dirname(full_path)
filename = form.name.data
self.storage.rename_path(full_path, self._separator.join([dir_base, filename]))
self.on_rename(full_path, dir_base, filename)
flash(gettext('Successfully renamed "%(src)s" to "%(dst)s"',
src=op.basename(path),
dst=filename), 'success')
except Exception as ex:
flash(gettext('Failed to rename: %(error)s', error=ex), 'error')

return redirect(return_url)
else:
helpers.flash_errors(form, message='Failed to rename: %(error)s')

if self.rename_modal and request.args.get('modal'):
template = self.rename_modal_template
else:
template = self.rename_template

return self.render(template, form=form, path=op.dirname(path),
name=op.basename(path), dir_url=return_url,
header_text=gettext('Rename %(name)s',
name=op.basename(path)))

就是重写FileAdmin中的一个方法和一个视图。

把secure_filename去掉了，虽然不安全，但是目前也没什么快速的方法了。

见到另一个解决方案是把汉字转拼音。使用pypinyin库。

把上传的文件名分解，汉字部分转拼音。字符继续保存。

然后数据库中建立对应关系。

还需要改下载的视图。

麻烦，留着以后加吧。
