🧹 Add task to remove placeholder file sets

[kirkkwang]

This commit will add a rake task to remove placeholder file sets from the Dickinson tenant. To test, set an environment variable with whatever cname you want to use and run the task. For example:

REMOVE_PLACEHOLDER_FILE_SETS_FROM="dev.hyku.test" rake hyku:remove_placeholder_file_sets

Ref:

• Create script to remove all instances of a specific file that has been uploaded in a tenant (placeholder PDF files) #912

Notes

This should only be run once and future file sets of the placeholder pdf should not appear.

Tested locally and it worked for me.

There may be an auto page size of 10,000 records. Meaning you might need to run this multiple times.

I like it that this task is dynamic and reusable + the query approach. well done! 🎉

@kirkkwang A few more thoughts:

This works but after going through QA it was kind of a pain having to remember to set the env var to test what I needed.

I think it would be nice if we could pass the cname when calling the rake task command. I also think the file name is a misnomer if we want this to be more dynamic.

I haven't tested this but maybe something like this?

# rename file to lib/tasks/remove_placeholders.rake

namespace :hyku do
  desc "Remove Hyku Commons placeholder file sets from tenants"
  task :remove_placeholder_file_sets, [:cnames] => :environment do |t, args|
    cnames = args[:cnames].split(',')
    cnames.each do |cname|
      account = Account.find_by(cname: cname)
      next unless account

      begin
        switch!(account.cname)
        puts "********************** switched to #{account.cname} **********************"

        file_set_titles = ["HykuCommonsPlaceholder.pdf", "hykuplaceholderarchives.pdf"]
        query = file_set_titles.map { |title| "title_tesim:\"#{title}\"" }.join(" OR ")
        file_sets = FileSet.where(query)
        file_sets.each { |file_set| file_set.destroy(eradicate: true) }
      rescue StandardError => e
        puts "********************** error: #{e} **********************"
      end
    end
  end
end

Then we could call the rake task and pass it an array of cnames
