从Rake文件中的任务调用方法

问题描述：

是否可以调用与任务位于同一rake文件中的方法?在下面的代码中，您可以看到我有一个名为get_search_url的方法，该方法将分配给url.

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

答

是的，这是绝对可能的.只需在名称空间之后定义这些方法即可；)

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
