Check friendship before retweeting.

[Chokitu]

So, I've been trying to fix a little script that I have here.

I am able to retweet the message that I want using Cursor Search, but I wanted to add a condition that the bot profile needs to be following the person before it retweets

Let’s say person A is followed by the bot and posts something like: #RTMe
But person B is not followed by the bot
and replies the same thing, but the bot only retweets persons A tweet
Note that the bot must be following the person, not the person following the bot

I've been trying to do it with

for page in tweepy.Cursor(api.friends, count=100).pages(): user_ids = [user.id for user in page]

and then checking a relation with
relation = api.show_friendship(source_id=user.id, target_id=user_ids)

But as I am getting the array for the user_ids I am not able to check one by one, If I am to make a for statement will probably consume too much memory, is there another way?

I'm not sure I understand what you're trying to do here. API.friends already returns users you're following. Why pass it back to API.show_friendship? If you already have the Tweet/Status object, you can simply check if the ID of the user who Tweeted is in your list (using the user attribute of the Status object and the corresponding id attribute of that User object, e.g. tweet.user.id), or if you wanted to check it in realtime, use API.show_friendship with that user ID.

Also, if you just wanted the IDs of the users you're following, you can use API.friends_ids instead.

In any case, to answer your question, you can use API.lookup_friendships to bulk lookup relationships to 100 user_ids at a time.

It's says that 'API' object has no attribute 'lookup_friendship'

[Harmon758]

The method in question is API.lookup_friendships with an s.

[Chokitu]

Oops, sorry. I will try that right now!

[Chokitu]

for tweet in tweepy.Cursor(api.search, q=('#RTME')).items(500):
			try:
				
				relation = api.lookup_friendships(user_ids = tweet.user.id)
				for friendship in relation:
					if(friendship.is_following):
					    tweet.favorite()

Am I doing something wrong?

[Harmon758]

Like I said, API.lookup_friendships can be used to bulk lookup relationships to 100 user_ids at a time. From the documentation, you can see that the user_ids parameter accepts a "list of user IDs". If you want to lookup a single relationship, you can use API.show_friendship, as you were attempting to do before.

For code block usage, see https://docs.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks.

I want to check for multiple relationships, tho.

[Harmon758]

You can use API.lookup_friendships to do so.
tweet.user.id is a single integer user ID here, corresponding to the ID of the user who posted each Tweet.

[Chokitu]

Oh, that makes sense. I was thinking about that.

So I can just do like:

following = api.friends_ids()

and then
friendships = api.lookup_friendships(user_ids = following)

[Harmon758]

API.friends_ids is a method, so it would be following = api.friends_ids(), but again, I'm not sure why you're doing this since API.friends_ids will already be returning IDs of users being followed.

Also note, API.friends_ids uses the GET friends/ids endpoint, which returns results in groups of up to 5,000 user IDs, so if you have more or are missing results, you'll need to paginate it with a Cursor object as well.

[Chokitu]

Yep, I was seeing that, I just created a new profile account not following anyone and tried it out. But for some reason its not working. I mean it is liking and retweeting the post. But its not checking properly if the person is being followed by me. I am trying to debug it, but not successfully so far. This is what I got

for tweet in tweepy.Cursor(api.search, q=('#EuQueroMuitoTestarIsso')).items(numeroTweets):
			try:
				seguindo = api.friends_ids()
				friendships = api.lookup_friendships(user_ids = seguindo) 
				for friendship in friendships:
					print(friendship.is_following)
					if(friendship.is_following):
						tweet.favorite()

[Harmon758]

For each search result, this is looking up all the users you're following; looking up the relationships for those users; for each relationship, checking if you're following them in that relationship, which of course you are, since you looked up all the users you're following to begin with; and then favoriting the same Tweet for each user you're following. This is redundant in almost every way.

Again, I'm not sure what you're trying to accomplish here. Like I said initially, if you want to check that the user who Tweeted is someone you're following, you can simply use API.show_friendship with that user ID. Otherwise, if you want to store and use a list of IDs of users you follow and compare against that list (perhaps to avoid hitting the rate limit of querying the GET friendships/show endpoint that API.show_friendship uses each time), you can use API.friends_ids.

Okay, I am sorry. I was very sleepy, I took a better look at the documentation and I feel really dumb now, thanks for the patience, everything is working great!
