GSWD Heroku Django manage.py问题

本文介绍了GSWD Heroku Django manage.py问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我在线上完成了一个很棒的django教程，但是在最后的heroku部署中遇到了一个问题。

这是django教程： gettingstartedwithdjango/en/lessons/introduction-and-launch/

我遇到的问题是最后一次打电话给heroku：

heroku python manage.py syncdb

这是我得到的错误：

（blog-venv）vagrant @ precise64：/ vagrant / projects / microblog $ heroku run python manage.py syncdb 运行`python manage.py syncdb`附加到终端... up.2530 追溯（最近的最后一次调用）：文件manage.py，第10行，< module> execute_from_command_line（sys.argv）文件/app/.heroku/python/lib/python2.7/site-packages/django/core/management/__init__.py，第443行，在execute_from_command_line utility.execute（）文件/app/.heroku/python/lib/python2.7/site-packages/django/core/management/__init__.py，第382行，执行 self.fetch_command（subcommand）.run_from_argv（self.argv）文件/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py ，第196行，在run_from_argv self.execute（* args，** options .__ dict__）文件/app/.heroku/python/lib/python2.7/site-packages/django/core /management/base.py，第232行，执行 output = self.handle（* args，** options）文件/app/.heroku/python/lib/python2.7/ site-packages / django / core / management / base.py，第371行，处理 return self.handle_noargs（** options）文件/app/.heroku/python/lib/python2 .7 / site-packages / django / core / management / commands / syncdb.py，第57行，在handle_noargs cursor = connection.cursor（）文件/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/__init__.py，第306行，在光标 cursor = self.make_debug_cursor（self._cursor（））文件/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2 /base.py，第177行，_cursor self.connection = Database.connect（** conn_params）文件/app/.heroku/python/lib/python2.7/site-packages /psycopg2/__init__.py，第178行，连接 return _connect（dsn，connection_factory = connection_factory，async = async） psycopg2.OperationalError：无法连接到服务器：没有这样的文件或目录服务器是否在本地运行，并在Unix域套接字/var/run/postgresql/.s.PGSQL.5432上接受连接？ （blog-venv）vagrant @ precise64：/ vagrant / projects / microblog $

任何想法

解决方案

据我所知（git中级知识）如果您忘记添加locals.py .gitignore文件并提交它，那么git存储库将仍然存在locals.py文件。

您必须从git存储库中删除该文件，因为它已包含在以前的提交中。

git rm --cached microblog / settings / local.py

然后将microblog / settings / local.py添加到.gitignore并提交更改。

一旦heroku看到正确的数据库设置。然后syncdb工作正常

DATABASES = {'default'：dj_database_url.config（）}

I worked my way through a great django tutorial online, but am having an issue with the final heroku deployment.

Here is the django tutorial: gettingstartedwithdjango/en/lessons/introduction-and-launch/

The issue I have is with the last call to heroku:

heroku python manage.py syncdb

Here is the error I get:

(blog-venv)vagrant@precise64:/vagrant/projects/microblog$ heroku run python manage.py syncdb Running `python manage.py syncdb` attached to terminal... up, run.2530 Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/__init__.py", line 443, in execute_from_command_line utility.execute() File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/__init__.py", line 382, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py", line 196, in run_from_argv self.execute(*args, **options.__dict__) File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py", line 232, in execute output = self.handle(*args, **options) File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/base.py", line 371, in handle return self.handle_noargs(**options) File "/app/.heroku/python/lib/python2.7/site-packages/django/core/management/commands/syncdb.py", line 57, in handle_noargs cursor = connection.cursor() File "/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/__init__.py", line 306, in cursor cursor = self.make_debug_cursor(self._cursor()) File "/app/.heroku/python/lib/python2.7/site-packages/django/db/backends/postgresql_psycopg2/base.py", line 177, in _cursor self.connection = Database.connect(**conn_params) File "/app/.heroku/python/lib/python2.7/site-packages/psycopg2/__init__.py", line 178, in connect return _connect(dsn, connection_factory=connection_factory, async=async) psycopg2.OperationalError: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

Any thoughts

解决方案

As far as I know ( git intermediate level knowledge ) If you forgot to add locals.py to the .gitignore file and committed it then the git repository will have the locals.py file still in it .

You have to remove the file from git repository since it was included in previous commits.

git rm --cached microblog/settings/local.py

Then add microblog/settings/local.py to .gitignore and commit the changes.

Once heroku sees the correct DATABASES setting . Then syncdb works fine

DATABASES = {'default' : dj_database_url.config() }
