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.

I'm using the following code to dynamically create vue components. I'd like them to communicate with the vuex store but it looks like they have no access to it. Does anyone know how to solve this?
...ANSWER
Answered 2021-Jun-14 at 15:52In order to have an access to this.$store property in your Vue components, you need to provide the created store to Vue instance.
Vuex has a mechanism to "inject" the store into all child components from the root component with the store option.
So, in your example this will be here:

QUESTION
The current setup works find when i check/uncheck boxes and submit to server.
however, when the page reloads or when i go to edit, the page loads fine and the checkbox is checking the right entries like this...
The problem here is when i click submit without touching any values, the array is submitted empty permission_ids: []
, they need to be clicked again in order to fire the OnChange()
and i can't do this automatically when i page loads since i'm new to Angular
So the issue here as i understand, that the checkboxes are checked but the value of the form isn't updated.
here are the code

Answered 2021-Jun-13 at 18:25It's because your javascript code is executed before DOM is fully loaded.
So you have two choices, either move

or place all your javascript code inside:

QUESTION
The app has:
- ListView listing player names from a DB table (only one column, so it is primary key)
- EditText to write the new name
- Button to update the name of player in the list
*there are more things, but i don´t want to make it more messy
I can click a name from the list and write a new name in the EditText. When you press the button that name is updated in the list.
Everything works correctly, but there is a problem. When I write a name that it is already in the list the app fails because primary keys cannot be repeated.
Is there some way to say "if EditText text already exists in the DB... then show a toast"
I already tried "if result of db.update is -1...then show a toast", but it doesn´t work.
This is the method in MainActivity:

You have a UNIQUE index on the NUM_JUG column (perhaps implicit if NON_JUG is defined with PRIMARY KEY) and you are using the standard update method which uses the default conflict action of ABORT and therefore fails if an attempt is made to duplicate a NOM_JUG value.
As secondary issue is that the SQLiteDatabase update
method returns the number of updates (see extract and link below) (same for updateWithOnConflict
). The number returned will never be -1 it will be 0 or more (0 indicating that no updates have been applied).
As per SQLite Database - Update
Returns
int the number of rows affected
Fix
To fix the main issue you should use the updateWithOnConflict
method. This takes a 4th parameter a conflict and you probably want IGNORE so you could use :-
QUESTION
Consider this input array which represents a graph:
...ANSWER
Answered 2021-Jun-11 at 21:46Let's discuss this a bit more abstractly.
A directed graph is the data structure we're really taking as input here. We have a set V
of vertices/nodes and a set E
of edges. Each edge is an ordered pair (v1, v2)
, where v1
and v2
are both vertices, representing an arrow from v1
to v2
. Here, we're representing the graph using the "adjacency list" representation.
The task is to find all the ways to topologically sort this graph.
We can describe the ways to topologically sort a graph as follows:
If we want to topologically sort the empty graph (the graph with no vertices), this is easy: the only way to do it is to output the empty sorting []
. So the list of all ways to topologically sort the empty graph will be [[]]
.
Now, let's consider the problem of topologically sorting a non-empty graph. Consider a sequence s
which is a topological sort of a non-empty graph G
. We can consider the first element of s
, which we will call x
, and the sequence of all the rest of the elements, which we call s'
.
We know that x
must be a node in G
, and we know that x
cannot have any predecessors in G
. In other words, there can be no node y
such that (y, x)
is an edge.
We also know that s'
must be a topological sort of G'_x
, which is G
but with the node x
(and all edges connecting to it) removed.
So to get all the topological sortings of G
, we must find all sequences with initial element x
and remaining elements s'
, such that x
is an element of G
with no predecessors and s'
is a topological sorting of G'_x
.
