Configuration¶

Redmine¶

To start making requests to Redmine you have to check the box Enable REST API in Administration -> Settings -> Authentication and click the Save button.

Hint

Some operations in Redmine require a user to have the needed permissions to perform them, that is why sometimes it is a good idea to create a special user with admin rights in Redmine which will be used only for the calls to Redmine REST API.

Parameters¶

Configuring Python-Redmine is extremely easy, the first thing you need to do is to import the Redmine object, which will represent the connection to the Redmine server:

from redminelib import Redmine

Location¶

Now you need to configure the Redmine object and pass it a few parameters. The only required parameter is the Redmine location (without the forward slash in the end):

redmine = Redmine('https://redmine.url')

Version¶

There are a lot of different Redmine versions out there and different versions support different resources and features. To be sure that everything will work as expected you need to tell Python-Redmine what version of Redmine you’re using. You can find the Redmine version by visiting the following address https://redmine.url/admin/info and taking the first 3 numbers, i.e. if you have a version of 5.0.4.stable.21982, Python-Redmine needs only the 5.0.4:

redmine = Redmine('https://redmine.url', version='5.0.4')

Authentication¶

Most of the time the API requires authentication. It can be done in 2 different ways:

using user’s regular login and password:

redmine = Redmine('https://redmine.url', username='foo', password='bar')

using user’s API key which is a handy way to avoid putting a password in a script:

redmine = Redmine('https://redmine.url', key='b244397884889a29137643be79c83f1d470c1e2fac')

The API key can be found on users account page when logged in, on the right-hand pane of the default layout.

Impersonation¶

As of Redmine 2.2.0, you can impersonate user through the REST API. It must be set to a user login, e.g. jsmith. This only works when using the API with an administrator account, this will be ignored when using the API with a regular user account.

redmine = Redmine('https://redmine.url', impersonate='jsmith')

If the login specified does not exist or is not active, you will get an exception.

DateTime Formats¶

Python-Redmine automatically converts Redmine’s date/datetime strings to Python’s date/datetime objects:

'2013-12-31'           -> datetime.date(2013, 12, 31)
'2013-12-31T13:27:47Z' -> datetime.datetime(2013, 12, 31, 13, 27, 47)

The conversion also works backwards, i.e. you can use Python’s date/datetime objects when setting resource attributes or in ResourceManager methods, e.g. filter():

datetime.date(2013, 12, 31)                 -> '2013-12-31'
datetime.datetime(2013, 12, 31, 13, 27, 47) -> '2013-12-31T13:27:47Z'

If the conversion doesn’t work for you and you receive strings instead of objects, you have a different datetime formatting than default. To make the conversion work you have to tell Redmine object what datetime formatting you’re using, e.g. if the string returned is 31.12.2013T13:27:47Z:

redmine = Redmine('https://redmine.url', date_format='%d.%m.%Y', datetime_format='%d.%m.%YT%H:%M:%SZ')

Timezone¶

Added in version 2.4.0.

Redmine REST API expects and returns all datetime attributes in UTC. As described in the previous section, by default Python-Redmine tries to convert datetime text representation to Python’s naive datetime object during attribute access and vice versa from Python’s datetime object to the text representation ignoring timezone information even if one exists. Since 2.4.0 a support for timezone aware datetime objects has been added via a timezone argument which accepts either a string in a form of ±HHMM which is a time offset from UTC in hours and minutes:

redmine = Redmine('https://redmine.url', timezone='-0930')

or any Python object which is a subclass of datetime.tzinfo:

from datetime import timezone

redmine = Redmine('https://redmine.url', timezone=timezone.utc)

Main difference between the two is that ±HHMM string doesn’t take DST into account, but requires no extra packages to work, while a proper Python object which is a subclass of datetime.tzinfo does, but may require you to install additional packages. If you’re on Python 3.9+, there is a built-in zoneinfo module which is a recommended way of specifying a timezone:

from zoneinfo import ZoneInfo

redmine = Redmine('https://redmine.url', timezone=ZoneInfo('America/Los_Angeles'))

If you’re on Python <3.9, there are several 3rd party packages that provide you with timezone databases and classes that can be used as a value for Python-Redmine’s timezone argument.

After setting a timezone attribute to the desired timezone, Python-Redmine will automatically convert Redmine’s datetime strings to Python’s aware datetime objects:

'2013-12-31T13:27:47Z' -> datetime.datetime(2013, 12, 31, 5, 27, 47, tzinfo=zoneinfo.ZoneInfo(key='America/Los_Angeles'))

The conversion will also work backwards, i.e. you can use Python’s aware datetime objects when setting resource attributes or in ResourceManager methods, e.g. filter():

datetime.datetime(2013, 12, 31, 5, 27, 47, tzinfo=zoneinfo.ZoneInfo(key='America/Los_Angeles')) -> '2013-12-31T13:27:47Z'

Exception Control¶

If a requested attribute on a resource object doesn’t exist, Python-Redmine will raise an exception by default. Sometimes this may not be the desired behaviour. Python-Redmine provides a way to control this type of exception.

You can completely turn it OFF for all resources:

redmine = Redmine('https://redmine.url', raise_attr_exception=False)

Or you can turn it ON only for some resources via a list or tuple of resource class names:

redmine = Redmine('https://redmine.url', raise_attr_exception=('Project', 'Issue', 'WikiPage'))

Connection Options¶

Python-Redmine uses Requests library for all the http(s) calls to Redmine server. Requests provides sensible default connection options, but sometimes you may have a need to change them. For example if your Redmine server uses SSL but the certificate is invalid you need to set a Requests’s verify option to False:

redmine = Redmine('https://redmine.url', requests={'verify': False})

Full list of available connection options can be found in the Requests documentation.

Hint

Storing settings right in the code is a bad habit. Instead store them in some configuration file and then import them, for example if you use Django, you can create settings for Python-Redmine in project’s settings.py file and then import them in the code, e.g.:

# settings.py
REDMINE_URL = 'https://redmine.url'
REDMINE_KEY = 'b244397884889a29137643be79c83f1d470c1e2fac'

# somewhere in the code
from django.conf import settings
from redminelib import Redmine

redmine = Redmine(settings.REDMINE_URL, key=settings.REDMINE_KEY)
