QUESTION
I'm getting all the Tweets that I need from a Twitter account. More than 200 Tweets; for example 500, 600, ...
I'm using the Tweepy library to help me to do this with Python, and I have created this object to do this.
...ANSWER
Answered 2021-Jun-14 at 18:22From the documentation for Twitter's standard search API that Tweepy's API.search uses:
Keep in mind that the search index has a 7-day limit. In other words, no tweets will be found for a date older than one week.
https://developer.twitter.com/en/docs/twitter-api/v1/tweets/search/guides/standard-operators also says:
The Search API is not a complete index of all Tweets, but instead an index of recent Tweets. The index includes between 6-9 days of Tweets.

QUESTION
I'm new to Reactjs and this is my first webapp created with it, so probably it is just a petty error this one I'm gonna ask you to help me with. Basically I'm trying to validate my form but it doesn't work. It doesn't matter if I fill the form or leave it blank, if I press the send button, it gets sent, complitely bypassing my validation system. This is my form component, I'm using emailjs to handle the email sending (it works perfectly). Also the state of the component gets updated without any problem, it's just the validation itself that gets bypassed. I hope you can help me:

Answered 2021-May-31 at 11:18I fixed the problem by calling the validation function inside the sendmail function as parameter of the if statement and using its boolean returned value, like this:
QUESTION
I am trying to implement celery in a microservices architecture.
I have ServiceA that need to call tasks on other services X,Y,Z.
In python, when I load my module prior to a task being registered by X, the whole module seems to be blocked.
Expectation: Regardless of queue state, when the python module is loaded I should see 'Starting caller.py.....' followed by a blocked/waiting task
Actual Result: I don't see the print statement. Later, when another service registers a task worker, the whole module then loads...
ServiceA

Answered 2021-May-28 at 18:01This was an issue with STDOUT and basic python configurations not directly related to celery.
Solution:
The function register() is in fact being called along with the initial print statements. You can see this by adding sys.stdout.flush() at varying points.
You can set the follow ENV param:
QUESTION
I'm trying to add a validation function in my form, but when I test it I get "Uncaught TypeError: Cannot read property 'handleValidation' of undefined". Since I'm new to reactjs (this is my first webapp made with react) I don't seem to be able to find where the error is. The behavior of this form is: when a user clicks on submit, it first performs the validation, then if valid submit the form via email (to do this I'm using emailjs). Like I said, it fails on the validation step (while everything else works fine, even the email). I hope you can help me, here is my form component:

Answered 2021-May-23 at 09:35Instead of making the options clickable links, you can redirect to the link using the onChange prop of the Autocomplete component.
I'm assuming each option in your vendorData has a name and also a link e.g.
