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 
Je serais aussi intéressé de savoir comment créer des catégories de manière programmatique !
EDIT : Ok, j’ai trouvé. Ajoutez quelque chose comme ceci dans votre fichier plugin.rb :
@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
