python - Odoo 14/Python：FileNotFoundError：[Errno 2] 没有这样的文件或目录：'/events/img\\models'
问题描述
我是 python 新手，不知道如何解决这个错误。请指导我。我的目标是将要上传的图像保存在图像字段中，以保存在位于我的“事件”模块下的名为“img”的子文件夹中。
我收到以下错误：
Odoo Server Error

这是完整的代码：
import base64
from PIL import Image
import os
from odoo import api, fields, models
from odoo.modules.module import get_module_resource
class Events(models.Model):
_name = 'events'
_description = 'Events Details'
@api.model
def _default_image(self):
image_path = get_module_resource('events', 'img', 'default_image.png')
return base64.b64encode(open(image_path, 'rb').read())
name = fields.Char(string="Event Name", size=200, required=True, index=True)

@api.onchange('id')
def _onchange_user(self):
if self.id:
self.update(self._sync_user(self.id, bool(self.image_1920)))
if not self.name:
self.name = self.id.name
@api.model
def create(self, vals):

for f in files:

events = super(Events, self).create(vals)
events_allocations = self.env['events']
for events_allocation in events_allocations:
events_dict = {
'name': events_allocation.name,
'description': events_allocation.description,

}
new_allocation = self.env['events'].create(events_dict)
new_allocation.sudo().action_approve()
return events
这是我要实现的目标的具体代码：
@api.model
def create(self, vals):
if vals.get('id'):
user = self.env['events'].browse(vals['id'])
vals.update(self._sync_user(user, vals.get('image_1920') == self._default_image()))
vals['name'] = vals.get('name', user.name)
# the subfolder where store saved images
newdir = '.\events\img'
# newdir = 'C:\virtual_odoo14\Scripts\odoo\addons\events\img' # the absolute path
# thumbnail size as tuple
thumb_size = (300, 300)
# to list all the files in the accessed directory
files = [f for f in os.listdir('.') if os.path.isfile(f)]
for f in files:
# to get the current working directory
pathname = f.getcwd()
# to splits a full pathname and returns a tuple containing the path and filename.
(dirname, filename) = f.path.split(pathname)
# if the path and filename of the image selected is not empty
if (dirname != " ") and (filename != " "):
new_name = filename
image = Image.open(f)
image.thumbnail(thumb_size)
# the image path and name will be saved in \events\img
image.save(os.path.join(newdir, new_name))
# the image url will be stored in the database
url = os.path.join(newdir, new_name)
events = super(Events, self).create(vals)
events_allocations = self.env['events']
for events_allocation in events_allocations:
events_dict = {
'name': events_allocation.name,
'description': events_allocation.description,
'event_type': events_allocation.event_type,
'status': events_allocation.status,
'start_at': events_allocation.start_at,
'end_at': events_allocation.end_at,
'created_at': events_allocation.created_at,
'updated_at': events_allocation.updated_at,

}
new_allocation = self.env['events'].create(events_dict)
new_allocation.sudo().action_approve()
return events
