Watir read from 2 files issue

Rails
1

Hello everybody,

I am somehow new in ruby&watir. All i want to do today its to fill a
form, and 2 fields are taken from 2 different files.(urlimages.txt and
title.txt) like you see in attACHMENT. After
all fields are filled will be hit the “upload” button. After this, the
2 fields (url images and titles) will be again filled with second line
from each file),press upload button,after this will be filled with 3th
line from each file…and soo on till the end of file lenght,assuming
that
booth have the same numbers of lines.

My tactic:i tried to open each file with file.open, after this:
file.readlines() then make a loop to read each line of files and fill
the fields, then click submit. BUT…because are 2 files i find hard to
fill the form (source_title and image_url_input) without losing the
readlines counter.I mean every time will be read first line of each
file,i dont want this.
What should i do? to create a global variable that will be the counter
of lines from files? please help!

here its my code:

require ‘rubygems’
require ‘watir’
Watir::Browser.default = “firefox”
goto_url(“http://www.imgfave.com/post”)
browser.text_field(:name,
“source_title”).set(“_line_from_C:\title.txt”)
browser.text_field(:id,
“image_url_input”).set(“_line_from_C:\urlimages.txt”)
browser.text_field(:name, “tags”).set(“funny images”)
browser.text_field(:name, “source_url”).set(“http://www.9gag.com”)
browser.button(:value,“Upload”).click

Hi, Calin,

Let me see if I understand this.

You basically have two files which contain the lines of data you want
to insert into two fields on this form. Assuming there is a one-to-one
match between these (i.e., first line of titles.txt goes with first
line of urlimages.txt, and so on), you could do the following:

titles = IO.readlines(“path/to/titles.txt”)
imgurls = IO.readlines(“path/to/urlimages.txt”)

Now you can loop through the arrays using a range:

(1…titles.count).each do |i|
broswer.text_field(:name, “source_title”).set(titles[i].strip)
browser.text_field(:name, “image_url_input”).set(imgurls[i].strip)

and rest of processing as you have it…

end

That scheme works if titles.txt and urlimages.txt aren’t very large
that you can suck them entirely into memory for the operation.

If that’s not the case (it’d have to be a huge pair of files), you
can also just read each line as you go through the loop:

titles = File.open(“path/to/titles.txt”)
imgurls = File.open(“path/to/urlimages.txt”)

This time, since you don’t know the number of lines ahead of time,
simply loop until end of file:

until titles.eof? or imgurls.eof?
broswer.text_field(:name, “source_title”).set(titles.gets.strip)
browser.text_field(:name, “image_url_input”).set(imgurls.gets.strip)

and rest of processing as you have it…

end

Can I clarify something? Which machine are the files on? The server
machine running Rails or the client PC running the browser?

Hey guys thanks for youre answers. this really helped me. It s nice that
you can find such great advices when you need them. thanks again. i will
apply and will come back with news.

Colin, i put the topic in wrong section, i am sorry. I am not running
the script on a server, was just a ruby issue.

Also, am thinking also to automate the writing into files step like
this: connect to a database from where will be taken regularry last
images and titles that will be writen to titles.txt and urlimages.txt.
(thru A cronjob or …) please advise if i can do something like
this, and what should be the easiest and safer way to do it.

thanks
