Does Redmine have a hook for this one?

Haven't looked into it.

If task created from email - notifications didn't work

I installed and configured redmine_slack, and added a project custom field for the Slack Channel. Redmine updates never appear in my default slack channel (redmine) and they never appear in the project's channel (techops) either. I have successfully used the slackbot to post into the room, so the callback url works. Any thoughts on what might be going on here? I didn't notice any logging in this plugin, so I'm not sure what's going on.

I installed the redmine-slack plugin into my Redmine (2.4.2.stable.11137) and used the URL from API "Incoming Webhooks" but nothing happens on changing issues.

Can it be that this plugin is outdated in respect to slack.com api?

I found something like "slack.com/callback/" in the source as default but the API gives me something like:

https://teamname.slack.com/services/hooks/incoming-webhook?token=xXxXxXxXxXxXxX

I needed to run

rake redmine:plugins:migrate RAILS_ENV=production

on installation. Perhaps you should include this in the README

Our team complains (rightfully so) of too much noise in the Redmine updates to Slack. Perhaps if the attachment text were hidden or configurable (e.g. show/don't show/only show status and assignee) it'd be less noisy.

So instead of

[Project] Peter Hassett created Task #41965: Title of issue
Body of issue

Status

Priority

It would just say

[Project] Peter Hassett created/closed/updated Task #41965: Title of issue

404 error resolved with this solution, but unable to configure chat, not working

Slack lets you change the icon it uses to present the notification from redmine. In the page where you setup incoming integrations it states:

Additionally, if you would like to override the icon configured for the integration, you can pass that in as an option, either with: 
"icon_url": "https://slack.com/img/icons/app-57.png" 
or 
"icon_emoji": ":ghost:"

I know it may seem like a small thing, but I assume the change in the code should be relatively simple. Seeing a redmine icon in slack would go a long way to making it seem on par with the other commercial offerings available on slack out of the box.

Thanks.

I'm fairly sure I followed all the instructions correctly...

I used git to grab the repo in the plugins directory, ran bundle install (everything installed except RMagick), restarted Redmine, and nada.

I tried running this and restarting Redmine and still no go:
rake redmine:plugins:migrate RAILS_ENV=production

I'm on the admin/plugins page and I see nothing.

For reference, these are the versions of the software being used:

Environment:
Redmine version 2.3.0.stable
Ruby version 1.8.7 (i386-linux)
Rails version 3.2.13
Environment production
Database adapter Mysql2
Redmine plugins:
no plugin installed

here i see, that actual version is 0.2 and this version supports redmine 3.0.x.
But when install this plugin from master the version is 0.1

And plugin not working for me.

You get a 500 error when updating issues. In the log you find the following error:

Hi,
I installed configured redmine slack plugin but not able get notifications for each issue update can any one help ,how to configure and how to use this this plugin

Slack webhook integration was tested outside of redmine using curl.

Installed redmine-slack using instructions in README. Plugin is configured, but no updates make it to slack. How do I go about troubleshooting this? I don't see any mention of the redmine_slack plugin in the redmine/log/production.log other than loading the configuration pages.

What i need to comment so plugin send only title (and description)?
I don't want see status,proirity,etc in message.
Tried to comment in listener.rb:

Hi to all,
I want to send notification to more then one slack teem. So i tried to add to Slack URL
both Webhook URLs
https://hooks.slack.com/services/.... https://hooks.slack.com/services/....
But this doesn't work. Can you help me?

Redmine 3.0.0 just came out, and it would be awesome if the Slack integration would also work for the new/current Redmine 3.x series. I'm already missing it ... :-/

I'm completely at a loss with Ruby and Ruby-on-Rails, so unfortunately I can't help here. :-(

Hey, I just installed your plugin and it worked on the first try. Thanks so much for this. I don't have the ability to troubleshoot this problem, but I thought you might want to know about it.

We use Redmine Helpdesk plugin (https://github.com/jfqd/redmine_helpdesk) and one of it's features it that you can email [email protected] and it will auto-create issues. Problem is, when the issue gets created, your Slack plugin does not notify my channel.

I am here to help in any way other than hands-on programming, just let me know what I can do. I can test, bridge the gap between you and the author of the Helpdesk plugin, etc.

On Description or Note updates there are html tags in the message.

e.g.
ew <br
d<br /

<'img alt="" data-rich-file-id="135" src="/redmine/system/rich/rich_files/rich_files/000/000/135/thumb/screen-20shot-202015-01-21-20at-2014-34-53.png" />

the plugin would use an option to strip all the html tags for a clean text

You can right click on items in an issue list and update their properties in "bulk". There is a redmine hook for this, too.

There's a chance I'll work on this in the near future. How does one print to the redmine log from inside the plugin?

Whenever I go into an actual issue ticket and update the status, the notification posts to our slack channel that the status has updated.

We are using Redmine's Agile plugin (http://www.redminecrm.com/projects/agile/pages/1) and the act of dragging and dropping a task from "New" to "In Progress" is essentially the same this as a status change. However, this does not send a notification to the slack channel.

We are using Redmine 3.0.0.

I could not run the plugin.

in the configuration of plugins I put the url of Slack:
Setup Instructions
Your slackbot URL is:
https://XXXXXXXXX.slack.com/services/hooks/slackbot?token=eiCjlEHekm5QujXRG2lXXXXXXX
in the field of slack channel I put #redmine (already created in Slack).
In the usuairo I put "redmine" but that user does not exist, that I put ??

I created the custom field in a project Channle Slack. reads it had to be a list.

When I add an issue returns error 505 and I do not have any details of the error, Slack I do not get any text.

Can you please update instructions to installing the plugin? It doesn't mention that you need the httpclient gem in order to run the plugin. I am not a ruby expert, so it took me a while to realize this.

I'm still trying to get it up and running.

Thanks.

Hey,

since I added redmine-slack all ticket creations and edits went super slow. Once I remove the plugin it is normal again. Would it be possible to implement it async. This also wouldn't break the service when slack is down/the connection to slack is failing.

It would be great to disable pushing of private tasks or to implement a setting to force pushing of private tasks.

hello. There are a liittle bag in last version.
Broken link to redmine issue. Please check screensht from slack
http://screencast.com/t/rf1yAoYTcQ3w
< link > causes that link doesn work in slach
thx for great plugin

In current version almost any changes are sending to slack, so channel is over flooding. Only some important changes (some statuses or description) should be send.

Hi,
Thanks for the plugin, which is really helpful.
After the plugin integration, I noticed that the redmine is responding too slow while creating and updating the issue. Could you please help me on whether I need to tweak anything here to improve the performance? We have thousands of issue records in our database, would this be a problem here?
Our environment details are as below
Environment:
Redmine version 2.3.0.stable
Ruby version 1.8.7 (i686-linux)
Rails version 3.2.13
Environment production
Database adapter MySQL

Slack plugin appears in redmine, but when I click "configure" I am taken to this url: mysite.com/redmine/settings/plugins/redmine_slack

And I see an error message as follows:

https://www.dropbox.com/s/3ik8asq0tuyiu3h/Screenshot%202014-09-04%2014.18.01.png?dl=0

Any suggestions?

Hello, I deploy redmine 2.5-stable on heroku with this plugin. When I click configure ({my-host}/settings/plugin/redmine_slack) on plugin page, it shows The page you were trying to access doesn't exist or has been removed.. Could you give me advices to resolve this? Thanks.

After I set up plugin and make new issue on Redmine, I got 500 Error. And logs are:

Rendering /usr/share/redmine/public/500.html (500 Internal Server Error)

Overview

I sort of hate to say it, but the docs seem to need improvement. It took me a while to figure this out, and even now i'm not 100% sure why it works the way it does. (i.e. why is my username the one I had to enter into the plugin to enable this functionality?)

Here's the original message I'd written, for an idea of my thought process on this and why the docs need some clarification. (I'd submit a pull request, but I'm still not sure why I had to enter my username).

Original Message

It's hard to tell what's going on, but I haven't been able to make this integration work. The plugin is installed, I've got an incoming webhook API URL pasted (https://hooks.slack.com/services/XXXXXX) and have created a channel in Slack for this.

And no dice. Redmine 3.0.4.

So - what am I missing?

What exactly is the "Slack Username" field for? Do I need to create a special slack account for this plugin? Is it the name of my company? (If I have to create a username for Slack, is the username the email address of the account I created?) Is it the listed "incoming-webhook?"

Does the "Slack Channel" have to match the one I created the web hook for? Do I use the leading # or not?

Plugin options I've tried:

• "Slack Username"
  • Company URL prefix
  • Redmine
  • incoming-webhook
• Slack Channel
  • #RedmineGeneral
  • #redminegeneral
  • redminegeneral

Hello, I think it would be great to add instruction what is Slack URL and how to register incoming web hook for this field in slack integration.

Awesome Gimp screenshot attached.

Hello. we have few projects in redmine, so we have different slack apps for every team.
How to use your great plugin for different slack apps and projects in one redmine?

So I'm not sure the channel name stuff will work?

Hi,
Looking forward to using this plugin but I'm getting a undefined method 'delete' for nil:NilClass when updating/creating an issue.

I'm on a somewhat dated platform..is that the problem ?
Environment:
Redmine version 2.3.2.stable
Ruby version 1.9.3-p385 (2013-02-06) [i386-mingw32]
Rails version 3.2.13

Help most appreciated

Cheers
Charlie

Hi, Sir,

I have a idea. It's the project push message to multi-channel. Because someone can get all message in the channel.

I thought it would be nice if we could send notification to private groups.
So I wrote an patch #60

Hi there !! I've installed the redmine-slack plugin. I can access to the plugin configuration and I've set the "Slack API URL" as the one I've generated in "Incoming webhook", there is a token included.

However, the integration does not work :(

When I tried to find the Integration for Redmine (form "Configure integration" in slack), I can't find it in the list of Service integration :(
It is normal ???

Thanks in advanced

in the company where I work and I have installed redmine a proxy authentication is used to surf the internet. I discovered that the problem in the slack plugin is that it fails to send the information via the proxy. search the internet and found that ruby ​​does not use proxy variables but requires use Net :: HTTP directly in the code. so there will see this suggestion to use the plugins? Thank you

We've installed and configured redmine-slack but the plugin doesn't send anything.
Incoming Web Hook is enabled. I've tried the curl code from Slack doc and it's working.

Could you please help me? Any suggestions? Thanks.

Redmine 2.2.2.stable

Hi, I have a redmine (bitnami) installation (redmine 2.4) - I went to my /opt/bitnami/apps/redmine/htdocs/plugin folder and did "bundle install", I also created a Gemfile and referenced httpclient (as given in one of your issues) and did bundle install.
When I list gem list, it shows me httpclient (2.6.0.1)

But, when I run redmine and try to access it, it gives an error (see below). And since my redmine itself doesn't run I have to remove the plugin so that the production is not affected. Let me know if I am doing something wrong.

Why? Did I missed something at the installation or is this a bug?

If redmine-slack using asynchronous method, it would be more smoothly.
