I am developing new community-hub plugin for discourse where any registered users can create categories for their group / community. So the plugin should create categories itself in some criteria.
Can anyone help me to do this programmatically via plugin. And I welcome contributors for my new plugin 
我也很想知道如何以编程方式创建分类!
编辑:好的,我弄明白了。在你的 plugin.rb 文件中加入类似下面的代码:
@cat = Category.new({"user_id"=> 1 ,"name"=>"bla", "color"=>"0088CC", "text_color"=>"FFFFFF", "permissions"=>{"everyone"=>"1"},"required_tag_group_name"=>"", "topic_featured_link_allowed"=>"true", "search_priority"=>"0"})
@cat.save
puts @cat.errors.inspect
