Anyone have any idea why the next cursor isn't changing in the below code?
cursor = "-1"
followerIds = []
while cursor != 0 do
followers = Twitter.follower_ids("IDTOLOOKUP",{"cursor"=>cursor})
cursor = followers.next_cursor
followerIds+= followers.ids
sleep(2)
end
After the first iteration where cursor = -1, it gets assigned the nextcursor from the twitter api. However, when this is sent to the twitter API on subsequent iterations, I get the same response back as I did the first time.. with the same next_cursor.
Any ideas what I'm doing wrong? I'm using the twitter gem.
Edit: [Suggestion regarding being rate limited removed]
The problem is the cursor option to follow_ids. It should read:
followers = Twitter.follower_ids("IDTOLOOKUP",{:cursor=>cursor})
Note the use of symbol, not string. In the original code, the "cursor" option being provided was being ignored and follower_ids was doing the default behavior, namely returning the first page of followers.

I'm building a Telegram bot that uses ConversationHandler to prompt the user for a few parameters and settings about how the bot should behave. This information is stored in some global variables since it needs to be available and editable by different functions inside the program. Every global variable is a dictionary in which each user is associated with its own value. Here's an example:
language = {123456: 'English', 789012: 'Italian'}
where 123456 and 789012 are user ids obtained from update.message.from_user.id inside each function.
After all the required information has been received and stored, the bot should send a message containing a text fetched from a web page; the text on the web page is constantly refreshed, so I want the message to be edited every 60 seconds and updated with the new text, until the user sends the command /stop.
The first solution that came to my mind in order to achieve this was something like
info_message = bot.sendMessage(update.message.chat_id, text = "This message will be updated...")
...
def update_message(bot, update):
while True:
url = "http://example.com/etc/" + language[update.message.from_user.id]
result = requests.get(url).content
bot.editMessageText(result, chat_id = update.message.chat_id, message_id = info_message.message_id)
time.sleep(60)
Of course that wouldn't work at all, and it is a really bad idea. I found out that the JobQueue extension would be what I need. However, there is something I can't figure out.
With JobQueue I would have to set up a callback function for my job. In my case, the function would be
def update_message(bot, job):
url = "http://example.com/etc/" + language[update.message.from_user.id]
result = requests.get(url).content
bot.editMessageText(result, chat_id = update.message.chat_id, message_id = info_message.message_id)
and it would be called every 60 seconds. However this wouldn't work either. Indeed, the update parameter is needed inside the function in order to fetch the page according to the user settings and to send the message to the correct chat_id. I'd need to pass that parameter to the function along with bot, job, but that doesn't seem to be possible.
Otherwise I would have to make update a global variable, but I thought there must be a better solution. Any thoughts? Thanks.
I had the same issue. A little digging into the docs revealed that you can pass job objects a context parameter which can then be accessed by the callback function as job.context.
context (Optional[object]) – Additional data needed for the callback function. Can be accessed through job.context in the callback. Defaults to None
global language
language = {123456: 'English', 789012: 'Italian'}
j=updater.job_queue
context={"chat_id":456754, "from_user_id":123456, "message_id":111213}
update_job = job(update_message, 60, repeat=True, context=context)
j.put(update_job, next_t=0.0)
def update_message(bot, job):
global language
context=job.context
url = "http://example.com/etc/" + language[context["from_user_id"]]
result = requests.get(url).content
bot.editMessageText(result,
chat_id = context["chat_id"],
message_id = context["message_id"])
I have been lumbered with a Ruby, Watir IE test program which I need to change.
It currently does this:-
browser.frame(:id,"ultraposuidialoghtm0").div(:class," content").button(:id,"ok").click
This issue I have is the first div ID can change, 0, 1, 2 etc.
How do I create a var that shows me the ID on the page?.
i.e. my = browser.frame(:id)
What would be the correct syntax?
I can't try this, but judging from the documentation you should be able to do it using a regex:
browser.frames(:id, /ultraposuidialoghtm/).each do |frame|
id = frame.id
# do whatever
end
What I need- some kind of way to grab the number entered into the form in order to check it against previous records PRIOR to updating, so that if a validation error occurs, the user can be prompted to confirm before the form is submitted. Params would work, but are only returned after the form is posted- so no help. Is there an ajax call that I can pass into a ruby variable? Or perhaps some kind of ruby code that will read the input in the text box without submitting or linking?
What I'm doing- I'm trying to set up a 'manual validation' because I don't want the validation to 'prevent' from saving. Instead, it should be more like a confirmation.
If you care for context, Here's the run-down- I have a client that pays monthly deposits. We confirm these deposits over the phone through a third party. Naturally, in order to get the most accurate data as possible, we have to account for human error and other factors. A deposit this month should never be less than a deposit last month- but deposits can be "moved" from one account to another, which would make it seem like it was less. I have a form that new data is input on, and I want it to check against previous records to see if the deposit is more or less than reported previously. If less, it should ask for confirmation- an "are you sure?" kind of thing.
The code is old & outdated, should be changed from the ground up, but would take months when I have days to do this. I'm just looking for a patch.
What I have so far- note that cur_deposit is this months and rec_deposit is last months.
<%
arr1 = []
arr2 = []
is_less = false
r = #recent_inquiries.last
r.inquiry_deposits.order(:id).each do |t|
arr1 << t.cur_deposit.to_f
arr1 << t.rec_deposit.to_f
end
#inquiry.inquiry_deposits.order(:id).each do |td|
#============THIS is the part that needs help
arr2 << params["cur_deposit_text_box"]
arr2 << params["rec_deposit_text_box"]
end
i = 0
while i < (arr1.size - 1)
comp_arr1 = []
comp_arr2 = []
comp_arr1 << arr1[i]
comp_arr1 << arr1[i + 1]
comp_arr2 << arr2[i]
comp_arr2 << arr2[i + 1]
if Inquiry.compare_deposits(comp_arr1, comp_arr2) != nil then is_less = true end
i = i + 2
end
if is_less
strConf = "A deposit from last month is greater than the same deposit this month, which should not happen. Are you sure?"
end
%>
<%= submit_tag "Save Inquiry", :onclick=>"$('#submit_form').val('Save Inquiry summary');", :class => 'tgButton3', :id => 'save_inquiry_button_bottom', :confirm => strConf %>
When I get this code working, I will stash all the functioning code into a model- I just have it in the view for testing. It is safe to assume that all the 'custom methods' this script calls to are functioning. If you need code from them, I'll happily share it.
Rails version 3.0.20
Can you use jQuery on your website? (if not it is doable in plain javascript)
$('#id-of-your-field').change(function(e){
//do here your client side logic if any needed
var yourfirstvalue = $(e.target).val();
//now take the value and send it to server (your ruby stuff)
$.ajax({
url: yourURL + "/" + yourfirstvalue,
success: function(data){
//this data can be sent as JSON in structure which suits the best to you
//so you can use it to populate your second dropdown
var values = JSON.parse(data);
//use your values
}
});
});
Google "combo box example" it might help you.
In order to close this question out, and in case anybody else is wondering, I will answer my own question. This is what I've found out.
Because of the nature of the relationship between client & server, there is really no way to get the value of the text input, store it in a ruby variable, and check it against another ruby variable. Ruby script only runs once and then is rendered, so while ajax may be able to continually run in the background and gather inputs, etc, the integration with ruby falls short when talking client-side only interaction. (Correct me if I'm wrong- after all, I posted the question to get everybody's input!)
The fix: I created a switch using hidden tags. When the form loads, the hidden tag is blank. After submitting the form, the update action checks the params of the newly entered data against the numbers from last month. If the conditions check out, it saves. If not, it re-loads the page with a message. If the message is confirmed, an ajax command changes the hidden tag to "true" which bypasses the comparison once it hits the update action again. Otherwise, the data is not saved. Problem solved!
I'm making this a community wiki answer in case anybody would like to add their two cents.
This is a sort of followup to my other MongoDB question about the torrent indexer.
I'm making an open source torrent indexer (like a mini TPB, in essence), and offer both SQLite and MongoDB for backend, currently.
However, I'm having trouble with the MongoDB part of it. In Sinatra, I get when trying to upload a torrent, or search for one.
In uploading, one needs to tag the torrent — and it fails here. The code for adding tags is as follows:
def add_tag(tag)
if $sqlite
unless tag_exists? tag
$db.execute("insert into #{$tag_table} values ( ? )", tag)
end
id = $db.execute("select oid from #{$tag_table} where tag = ?", tag)
return id[0]
elsif $mongo
unless tag_exists? tag
$tag.insert({:tag => tag})
end
return $tag.find({:tag => tag})[:_id] #this is the line it presumably crashes on
end
end
It reaches line 105 (noted above), and then fails. What's going on? Also, as an FYI this might turn into a few other questions as solutions come in.
Thanks!
EDIT
So instead of returning the tag result with [:_id], I changed the block inside the elsif to:
id = $tag.find({:tag => tag})
puts id.inspect
return id
and still get an error. You can see a demo at http://torrent.hypeno.de and the source at http://github.com/tekknolagi/indexer/
Given that you are doing an insert(), the easiest way to get the id is:
id = $tag.insert({:tag => tag})
id will be a BSON::ObjectId, so you can use appropriate methods depending on the return value you want:
return id # BSON::ObjectId('5017cace1d5710170b000001')
return id.to_s # "5017cace1d5710170b000001"
In your original question you are trying to use the Collection.find() method. This returns a Mongo::Cursor, but you are trying to reference the cursor as a document. You need to iterate over the cursor using each or next, eg:
cursor = $tag.find_one({:tag => tag})
return cursor.next['_id'];
If you want a single document, you should be using Collection.find_one().
For example, you can find and return the _id using:
return $tag.find_one({:tag => tag})['_id']
I think the problem here is [:_id]. I dont know much about Mongo but `$tag.find({:tag => tag}) is probably retutning an array and passing a symbol to the [] array operator is not defined.
I have been trying to write a script that may help me to comment from command line.(The sole reason why I want to do this is its vacation time here and I want to kill time).
I often visit and post on this site.So I am starting with this site only.
For example to comment on this post I used the following script
require "uri"
require 'net/http'
def comment()
response = Net::HTTP.post_form(URI.parse("http://www.geeksforgeeks.org/wp-comments-post.php"),{'author'=>"pikachu",'email'=>"saurabh8c#gmail.com",'url'=>"geekinessthecoolway.blogspot.com",'submit'=>"Have Your Say",'comment_post_ID'=>"18215",'comment_parent'=>"0",'akismet_comment_nonce'=>"70e83407c8",'bb2_screener_'=>"1330701851 117.199.148.101",'comment'=>"How can we generalize this for a n-ary tree?"})
return response.body
end
puts comment()
Obviously the values were not hardcoded but for sake of clearity and maintaining the objective of the post i am hardcoding them.
Beside the regular fields that appear on the form,the values for the hidden fields i found out from wireshark when i posted a comment the normal way.I can't figure out what I am missing?May be some js event?
Edit:
As few people suggested using mechanize I switched to python.Now my updated code looks like:
import sys
import mechanize
uri = "http://www.geeksforgeeks.org/"
request = mechanize.Request(mechanize.urljoin(uri, "archives/18215"))
response = mechanize.urlopen(request)
forms = mechanize.ParseResponse(response, backwards_compat=False)
response.close()
form=forms[0]
print form
control = form.find_control("comment")
#control=form.find_control("bb2_screener")
print control.disabled
# ...or readonly
print control.readonly
# readonly and disabled attributes can be assigned to
#control.disabled = False
form.set_all_readonly(False)
form["author"]="Bulbasaur"
form["email"]="ashKetchup#gmail.com"
form["url"]="9gag.com"
form["comment"]="Y u no put a captcha?"
form["submit"]="Have Your Say"
form["comment_post_ID"]="18215"
form["comment_parent"]="0"
form["akismet_comment_nonce"]="d48e588090"
#form["bb2_screener_"]="1330787192 117.199.144.174"
request2 = form.click()
print request2
try:
response2 = mechanize.urlopen(request2)
except mechanize.HTTPError, response2:
pass
# headers
for name, value in response2.info().items():
if name != "date":
print "%s: %s" % (name.title(), value)
print response2.read() # body
response2.close()
Now the server returns me this.On going through the html code of the original page i found out there is one more field bb2_screener that i need to fill if I want to pretend like a browser to the server.But the problem is the field is not written inside the tag so mechanize won't treat it as a field.
Assuming you have all the params correct, you're still missing the session information that the site stores in a cookie. Consider using something like mechanize, that'll deal with the cookies for you. It's also more natural in that you tell it which fields to fill in with which data. If that still doesn't work, you can always use a jackhammer like selenium, but then technically you're using a browser.
