Call methods from a task in Rake files

It is possible to call a method which is in the same rake file as the task? In the code below you can see that I have the method call get_search_url which will be assigned to url.

namespace :populate do
desc "ETC"
task :db => :environment do

    Report.where(link: "").each do |word|
        url = get_search_url(word.name)
        doc = Nokogiri::HTML(open(url))
        word.update_columns(link: link)
    end
end

def get_search_url(keyword)
    return "URL/keyword"
end

end

However if you define the same method in two different rake tasks, they will both be globally loaded when running rake, and one of the method definitions will be redefined / overwritten by the other!

Better practice is to define methods in a separate module and then include that module in your rake file. See https://kevinjalbert.com/defined_methods-in-rake-tasks-you-re-gonna-have-a-bad-time/ (Solution #3)

Yes it is absolutely possible. Just define those methods after the namespace ;)

namespace :populate do
desc "ETC"
task :db => :environment do

    Report.where(link: "").each do |word|
        url = get_search_url(word.name)
        doc = Nokogiri::HTML(open(url))
        word.update_columns(link: link)
    end
end

end

def get_search_url(keyword)
    return "URL/keyword"
end
