[Trac] AttributeError: 'Environment' object has no attribute 'get_db_cnx'

[ivanelson]

After upgrading to version 1.2. I'm having this error while trying to 
create a ticket:

It looks like something on the plugin side. However, it seems that no one 
has opened a [1] ticket for the plugin fix.

[Trac] AttributeError: 'Environment' object has no attribute 'get_db_cnx'

[Mike Dewhirst]

How can I deal with this?

There seem to be a number of tickets discussing this error and my 
interpretation is it should be fixed in 1.2. However, I have recently 
upgraded from 1.0 to 1.2 as indicated below in the Trac version. 
However, when I click on the Plugins page Trac 1.0 appears instead of 
1.2.2. Maybe that is evidence I did it badly. An earlier thread "[Trac] 
Re: multiple projects transition from a single project​" finishing on 28 
September covers Ryan's valiant and eventually successful effort to get 
me going again a couple of weeks ago.


It is reproducible by clicking [Save changes] at the /General\ tab on 
the Preferences page. All the other tabs with [Save changes] work 
without error.


It is also reproducible by clicking [Restart] on the Accounts | 
Configuration | Password Refresh section (at .../admin/accounts/config) 
whether Silently update password hashes ... is ticked or not


It is also reproducible by clicking the Accounts | Users link on the 
same page (at .../admin/accounts/config)


I couldn't find the error elsewhere. But in trying things, I did 
discover a Custom Fields KeyError: 'width' which I'll now write up in a 
separate thread.


I have all the _ADMIN permissions including ACCTMGR_ADMIN, 
ACCTMGR_CONFIG_ADMIN and ACCTMGR_USER_ADMIN


Thanks for any hints.

Mike


 Oops…

*Trac detected an internal error:*

AttributeError: 'Environment' object has no attribute 'get_db_cnx'

This is probably a local installation issue.


   Found a bug in Trac?

If you think this should work and you can reproduce the problem, you 
should consider creating a bug report.


Note that the following plugins seem to be involved: TracAccountManager, 
TracVote*Please report this issue to the plugin maintainer.*


Before you do that, though, please first try*searching 
for 
similar issues*, as it is quite likely that this problem has been 
reported before. For questions about installation and configuration of 
Trac or its plugins, please try themailing list 
instead of creating a ticket.


Otherwise, pleasea new bug report describing the problem and explain how 
to reproduce it.

[Trac] AttributeError: 'Environment' object has no attribute 'get_db_cnx'

[Jesus Megia]

Hello,

I'm updating the trac version on my company from version 0.11 to 1.6. 
Everything is working fine except the trac-pre-commit-hook which show me 
this error message:

* AttributeError: 'Environment' object has no attribute 'get_db_cnx'*

I have tried different pyton trac-pre-commit-hook versions but all of them 
give me the same output.

Can you help me to try to solve the problem?

Thans in advance.

You need to install version 0.5dev of TracAccountManager. Suggested steps:

$ pip uninstall TracAccountManager
$ pip install svn+https://trac-hacks.org/svn/accountmanagerplugin/trunk

Repeat the "uninstall" command until it reports "not installed". It's 
common to have eggs installed for multiple versions if you haven't been 
using pip previously, since setuptools does not provide an uninstall tool.

Thanks for your quick response! This must be being caused by a different 
issue, although the error message is the same. The error is occuring while 
trying to enable the Agilo trac plugin. Maybe it is better to head over to 
Agilo to fix this?

Hm.  Directory ./log is empty. Is it somewhere else?

Let's start over. Where did you see the error "AttributeError: 
'Environment' object has no attribute 'get_db_cnx'"? If you saw it on page 
while navigating Trac, please send a screen capture.

Re: [Trac] AttributeError: 'Environment' object has no attribute 'get_db_cnx'

[David S]

Error is occurring on the command line when trying to upgrade the database, 
after enabling Agilo plug-in in trac.ini (agilo.* = enabled). Trac is 
installed in a virtualenv. After a new project is created, Agilo 
installation requires adding to trac.ini. Agilo's docs state only to add 
"agilo.* = enabled". Adding only this line and running upgrade results in 
the output: "Database is up to date, no upgrade necessary." This is invalid 
because elsewhere it is stated that this command ought to produce updates 
to the database. However, on trac installation for plug-ins, it states to 
add plug-ins under a section titled "[component]". Adding this section to 
trac.ini, then adding "agilo.* = enabled" below this, results in the error 
below:

$ uname -a
> Linux localhost.localdomain 4.14.14-200.fc26.x86_64 #1 SMP Fri Jan 19 
> 13:27:06 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

$ trac-admin /home/user/Development/TracEnv/TracProject/ upgrade

I'm pretty sure Agilo doesn't yet support Trac 1.2.

You can get more information on the AttributeError from the log file, which
will be at:
 /home/user/Development/TracEnv/TracProject/log/trac.log

In the log file there should be a traceback showing leading up to the
exception "AttributeError". The traceback shows where the exception
originated, and propagation up the call stack.

Ah, okay. Oops, did not consider a version issue. Thanks. Will start 
over with a trac version compatible with aglio :)

Re: [Trac] AttributeError: 'Environment' object has no attribute 'get_db_cnx'

[David S]

Okay, it works now. Just to clarify from previous post, in trac.ini it is 
"[components]" not "[component]". And adding under "[components]" was still 
necessary before upgrade processed. Thanks again ;)
