我有两张桌子," Que"和" Opts"。
我想遍历Que中的所有记录,并将它们添加到变量rikt_nr
,start_nr
和end_nr
,因为它们将放在URL的末尾,这将是看起来像:
api.url.number=8-00001
如何让它在Que中进行迭代并将rikt_nr
,start_nr
和end_nr
传递给代码的其余部分?
Que表包含以下字段:
create_table "ques", force: true do |t|
t.integer "rikt_nr"
t.integer "start_nr"
t.integer "end_nr"
t.datetime "created_at"
t.datetime "updated_at"
end
和Opts有这些字段:
create_table "opts", force: true do |t|
t.string "numbers"
t.string "operator"
t.datetime "created_at"
t.datetime "updated_at"
end
这是代码:
Que.all.each do | que |
url = "http://api.url.number="
que.rikt_nr = rikt_nr
que.start_nr = start_nr
que.end_nr = end_nr
st_en = start_nr..end_nr
st_en.each do |nr|
full_url = "#{url}" + rikt_nr.to_s + "-"+ nr.to_s
doc = Nokogiri::XML(open(full_url))
number = doc.at('Number').text
operator = doc.at('Name').text
number_operator = "#{number}" + ";" + " #{operator}"
number_operator
save = @opts.create(:numbers => number, :operator => operator)
end
end
答案 0 :(得分:0)
我刚发现了这个。
问题在于:
que.rikt_nr = rikt_nr
que.start_nr = start_nr
que.end_nr = end_nr
st_en = start_nr..end_nr
所以我改成了:
Que.all.each do | que |
url = "http://api.url.number="
st_en = que.start_nr..que.end_nr
st_en.each do |nr|
full_url = "#{url}" + que.rikt_nr.to_s + "-"+ nr.to_s
doc = Nokogiri::XML(open(full_url))
number = doc.at('Number').text
operator = doc.at('Name').text
number_operator = "#{number}" + ";" + " #{operator}"
number_operator
save = @opts.create(:numbers => number, :operator => operator)
end
end
它现在有效。
