</form>
在我的项目中我想：
1)创建存储库、新的 Django 项目并首次提交。
2)安装Django Environ，通过.env文件上传配置。
配置必须允许您配置：
Aziendal API 的身份验证（URL，版本，用户名，密码）
path 保存待转录的新文件的目录
文件名模式（带有用于替换各种组件的占位符，例如日期、源名称、标题、语言、时间）
3) 创建转录模型以保存有关转录中发送的内容的信息。
方案：
ID
file_name 方法（字符串）
created_at（日期时间）
updated_at（日期时间）
4)
为 Aziendal API 实现一个迷你客户端，用于 GET 检索按名称过滤的源，并使用查询参数进行呈现检索。
使用配置文件中配置的身份验证。
5)
实现一个带有表单的页面，以加载包含以下字段的新成绩单：
日期（日期）
来源（select 来源取自 API）
语言（select 取自配置）
标题
可能的配置文件（可选）
请帮助一个年轻的初学者。
如果您需要我的项目的一些源代码，请询问:)
感谢帮助

这里最紧迫的问题是您在导入时尝试通过
加载会话来进行数据库调用
File "C:\Users371\audioma_manager\transcription_form\forms.py", line 5, in <module>
source_choice=GetAPISources.call_api(GetAPISources,endpoint='sources')
File "C:\Users371\audioma_manager\transcription_form\client_transcpition_api.py", line 48, in call_api
session_stored = s.load()
File "C:\Users371\AudioManVenv\lib\site-packages\django\contrib\sessions\backends\db.py", line 43, in load
s = self._get_session_from_db()
这是 Django 中的一个大禁忌，会导致先有鸡还是先有蛋的问题：
- 您需要进行迁移和 运行 迁移以创建数据库 tables
- Django 需要能够导入您的应用程序才能这样做
- 您的应用程序尝试从目前尚不存在的 table（因为它尚未迁移）进行数据库查询。
您需要 source_choice 在例如__init__ 表单时间，而不是导入时间。
目前，您可以将 source_choice=... 行替换为 source_choice=[] – 您将没有任何来源可供选择，但您可以进行迁移 运行宁.
除此之外，与会话相关的代码看起来很奇怪，尤其是，因为您正试图在请求上下文之外这样做。在这种情况下将不会加载有效会话，因为也没有请求。我认为您可能会将 Django 会话与您正在使用的 API 所要求的任何内容混淆。

if form.is_valid():
# process the data in form.cleaned_data as required
# redirect to a new URL:
#this url is only temp, evaluate better how to do
return HttpResponseRedirect('/thanks/')
else:
form = upload()
return render(request, 'upload.html', {'form': form})
我的模板：
<!DOCTYPE html>
{% Block Content %}
<h2>Upload</h2>
<form enctype="multipart/form-data" method="post" action="/foo/">
<!-- we need to use this token bc Django makes security controls and requires this token
to be recognize as trust source of code -->
{% csrf_token %}
{{form}}
<input type="file" name="recupero">
<button type="submit">Invio</button>
</form>
在我的项目中我想：
1)创建存储库、新的 Django 项目并首次提交。
2)安装Django Environ，通过.env文件上传配置。 配置必须允许您配置： Aziendal API 的身份验证（URL，版本，用户名，密码） path 保存待转录的新文件的目录 文件名模式（带有用于替换各种组件的占位符，例如日期、源名称、标题、语言、时间）
3) 创建转录模型以保存有关转录中发送的内容的信息。 方案： ID file_name 方法（字符串） created_at（日期时间） updated_at（日期时间）
4) 为 Aziendal API 实现一个迷你客户端，用于 GET 检索按名称过滤的源，并使用查询参数进行呈现检索。 使用配置文件中配置的身份验证。
5) 实现一个带有表单的页面，以加载包含以下字段的新成绩单： 日期（日期） 来源（select 来源取自 API） 语言（select 取自配置） 标题 可能的配置文件（可选）
请帮助一个年轻的初学者。 如果您需要我的项目的一些源代码，请询问:) 感谢帮助 xoxo
这里最紧迫的问题是您在导入时尝试通过
加载会话来进行数据库调用 File "C:\Users371\audioma_manager\transcription_form\forms.py", line 5, in <module>
source_choice=GetAPISources.call_api(GetAPISources,endpoint='sources')
File "C:\Users371\audioma_manager\transcription_form\client_transcpition_api.py", line 48, in call_api
session_stored = s.load()
File "C:\Users371\AudioManVenv\lib\site-packages\django\contrib\sessions\backends\db.py", line 43, in load
s = self._get_session_from_db()
这是 Django 中的一个大禁忌，会导致先有鸡还是先有蛋的问题：
- 您需要进行迁移和 运行 迁移以创建数据库 tables
- Django 需要能够导入您的应用程序才能这样做
- 您的应用程序尝试从目前尚不存在的 table（因为它尚未迁移）进行数据库查询。
您需要 source_choice 在例如__init__ 表单时间，而不是导入时间。
目前，您可以将 source_choice=... 行替换为 source_choice=[] – 您将没有任何来源可供选择，但您可以进行迁移 运行宁.
除此之外，与会话相关的代码看起来很奇怪，尤其是，因为您正试图在请求上下文之外这样做。在这种情况下将不会加载有效会话，因为也没有请求。我认为您可能会将 Django 会话与您正在使用的 API 所要求的任何内容混淆。
