Discourse Installation

copy-pasted from the Github readme

You can use this discourse translator plugin to translate Discourse topics. To install it simply modify /var/discourse/containers/app.yml :

## Plugins go here
## see https://meta.discourse.org/t/19157 for details
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/LibreTranslate/discourse-translator
	  ...

Then issue ./launcher rebuild app . From the Discourse’s admin panel then select “LibreTranslate” as a translation provider and set the relevant endpoint configurations.

I’m not the author, but just discovered this amazing plugin. Afaik no one has mentioned it on the forum. This will need to be turned into a plugin topic and hopefully we can get the dev on this chat… unless I’m totally missing where this plugin is already listed in meta.*

我尝试设置这个，但在最后一步（获取翻译）时，我遇到了以下错误消息：

发生错误： #<Excon::Response:0x00007f25419e6818 @data={:body=>"<!doctype html>\n<html>\n<title>405 Method Not Allowed</title>\n<h1>Method Not Allowed</h1>\n<p>The method is not allowed for the requested URL.</p>\n", :cookies=>[], :host=>"172.17.0.1", :headers=>{"Access-Control-Allow-Credentials"=>"true", "Access-Control-Allow-Headers"=>"Authorization, Content-Type", "Access-Control-Allow-Methods"=>"GET, POST", "Access-Control-Allow-Origin"=>"*", "Access-Control-Expose-Headers"=>"Authorization", "Access-Control-Max-Age"=>"1728000", "Allow"=>"HEAD, GET, OPTIONS", "Content-Length"=>"153", "Content-Type"=>"text/html; charset=utf-8", "Date"=>"Sat, 17 Dec 2022 11:18:27 GMT", "Server"=>"waitress"}, :path=>"//languages", :port=>5000, :status=>405, :status_line=>"HTTP/1.1 405 METHOD NOT ALLOWED\r\n", :reason_phrase=>"METHOD NOT ALLOWED", :remote_ip=>"172.17.0.1", :local_port=>50848, :local_address=>"172.17.0.3"}, @body="<!doctype html>\n<html>\n<title>405 Method Not Allowed</title>\n<h1>Method Not Allowed</h1>\n<p>The method is not allowed for the requested URL.</p>\n", @headers={"Access-Control-Allow-Credentials"=>"true", "Access-Control-Allow-Headers"=>"Authorization, Content-Type", "Access-Control-Allow-Methods"=>"GET, POST", "Access-Control-Allow-Origin"=>"*", "Access-Control-Expose-Headers"=>"Authorization", "Access-Control-Max-Age"=>"1728000", "Allow"=>"HEAD, GET, OPTIONS", "Content-Length"=>"153", "Content-Type"=>"text/html; charset=utf-8", "Date"=>"Sat, 17 Dec 2022 11:18:27 GMT", "Server"=>"waitress"}, @status=405, @remote_ip="172.17.0.1", @local_port=50848, @local_address="172.17.0.3">

我根据文档设置了一个带有 docker run -d --restart unless-stopped -ti -p 5000:5000 --name="libretranslate" libretranslate/libretranslate 的 Docker 容器，这对我来说似乎没问题，并将 translator libretranslate endpoint 设置为 http://172.17.0.1:5000（IP 是 Docker 主机 IP）。

根据错误消息，Discourse 也可以连接到 LibreTranslate，但有些东西不起作用。

有什么想法吗？

已解决 :slight_smile: : Problem with LibreTranslate as Docker for Discourse - #3 by pierotofy - LibreTranslate API - LibreTranslate Community

您需要更新到 Discourse 插件的最新 Github 版本。

@Roi 能否请您帮忙澄清一下这是如何设置的。我很困惑。我使用 sudo docker inspect libretranslate 找到了我的 docker 容器 IP。

根据您链接的帖子，API 端点是否被视为：

http://dockerip:5000

并且不需要 API 密钥？我正在与 Discourse 一起运行 libretranslate 容器。谢谢！

@sunjam 是的，我使用：

http://172.17.0.1:5000/

其中 172.17.0.1 是 Libretranslate Docker 容器的 IP 地址。

而且我没有使用 API 密钥。

@Roi 谢谢，看起来这是你的运行命令：

docker run -d --restart unless-stopped -ti -p 5000:5000 --name="libretranslate" libretranslate/libretranslate

某种程度上是的：

docker run -d --restart unless-stopped -ti -p 5000:5000 -e LT_LOAD_ONLY="en,de,fr,it,es,pt,nl,da,sv,pl,cs,ru" --name="libretranslate" libretranslate/libretranslate

也在此处向 Libretranslate 报告，但在尝试将 Libretranslate 与 Multilingual 和 Translator 应用程序一起使用时，我遇到了一个错误和警告。
