API call to watch categories and tags

rriemann is looking for API calls to watch categories and tags by default for existing accounts, but couldn’t find them in the Discourse API documentation. tobiaseigen suggested a possible solution using a plugin.

rriemann created a Ruby snippet to execute in the Rails console to watch a category by default for a group, and shared another untested snippet to watch a tag by default.

Jane_Polly_Macky and jack2 are also interested in implementing this feature, specifically looking for a way to opt users in to watch tags and request category/tag watching from the API or a plugin client-side code. jack2 shared a related topic on creating a follow button for a topic.

Hello,

I added a new watch-by-default category and have to add it to the watching list of all existing accounts. I have not found a correponding API call in our How-to: Discourse REST API Documentation

I am also looking for an API call to add given tags to the watch list for a given account.

All the best,
Robert

Based on the plugin, I wrote a ruby snippet to execute in the rails console (get a shell in your docker using ./launcher enter app and then rails c).

# based on https://github.com/discourse/discourse-watch-category-mcneel/blob/master/plugin.rb

# let a group watch or watch_first_post a category

group_name = "trust_level_0"
category_slug = "news"

group = Group.find_by_name(group_name)
category = Category.find_by_slug(category_slug)

unless category.nil? || group.nil?
  group.users.each do |user|
    # levels: :watching :watching_first_post
    level = :watching_first_post
    watched_categories = CategoryUser.lookup(user, level).pluck(:category_id)
    CategoryUser.set_notification_level_for_category(user, CategoryUser.notification_levels[level], category.id) unless watched_categories.include?(category.id)
  end
end

I had some troubles when I pasted the code into the console due to less that displays the results of the query for the group and category and consumes apparently some following code lines.

The same for tags, but yet untested:

# based on https://github.com/discourse/discourse-watch-category-mcneel/blob/master/plugin.rb

# watch tag

group_name = "trust_level_0"
tag_name = "newstag"

group = Group.find_by_name(group_name)
tag = Tag.find_by_name(tag_name)

unless tag.nil? || group.nil?
  group.users.each do |user|
    # levels: :watching :watching_first_post
    level = :watching_first_post
    watched_tags = TagUser.lookup(user, level).pluck(:tag_id)
    TagUser.change(user.id, tag.id, TagUser.notification_levels[level]) unless watched_tags.include?(tag.id)
  end
end

Any further testing or implementation / use of this? I’m looking for a way to ‘opt’ users in to watch tags :slight_smile:

I’m interested in this as well. Any way to request category/tag watching from the API or a plugin client-side code?
