QUESTION
I am having problems getting data from a element using Selenium with the line:
...ANSWER
Answered 2021-Jun-15 at 20:06When an element has spaces in the class
attribute, that means it has multiple classes, so you'll need to handle that another way.
One option is with CSS selectors.

OK, this seems rather simple and I've looked for another answer, but perhaps I'm not searching for the right thing. I have a list of URLs and pages containing those URLS
...ANSWER
Answered 2021-Jun-15 at 17:12You can do this as you are reading/separating the parts. I don't know how you're doing that, but the below assumes you have read lines from a file into an array. Just use the parent as the key and append []
each destination to the array:
QUESTION
I have a website which displays WMS data using Leaflet, and I've successfully set up a bootstrap datepicker where you can only select a date from an array of dates, using the beforeShowDay
method.
I'm now trying to set up the datepicker so that when I change map layer on the website, the bootstrap datepicker will update its available dates from the newly updated list of layer dates (for the new layer). I've attempted to update the beforeShowDay
function as in this answer and also tried to destroy and reinitialise the datepicker as seen here. Neither of these approaches worked.
Below is the code I'm using to set up the datepicker:

Answered 2021-Jun-15 at 08:49There are two approaches you can take here :
Approach 1 : //remove your current dateTimePicker and re-initialize it with the new date range

QUESTION
I am using the SQL connector to capture CDC on a table that we only expose a subset of all columns on the table. The table has two unique indexes A & B on it. Neither index is marked as the PRIMARY INDEX but index A is logically the primary key in our product and what I want to use with the connector. Index B references a column we don't expose to CDC. Index B isn't truly used in our product as a unique key for the table and it is only marked UNIQUE as it is known to be unique and marking it gives us a performance benefit.
This seems to be resulting in the error below. I've tried using the message.key.columns
option on the connector to specify index A as the key for this table and hopefully ignore index B. However, the connector seems to still want to do something with index B
- How can I work around this situation?
- For my own understanding, why does the connector care about indexes that reference columns not exposed by CDC?
- For my own understanding, why does the connector care about any index besides what is configured on the CDC table i.e. see CDC.change_tables.index_name documentation
ANSWER
Answered 2021-Jun-14 at 17:35One of the contributors to Debezium seems to affirm this is a product bug https://gitter.im/debezium/user?at=60b8e96778e1d6477d7f40b5. I have created an issue https://issues.redhat.com/browse/DBZ-3597.
Edit:
A PR was published and approved to fix the issue. The fix is in the current 1.6 beta snapshot build.
There is a possible workaround. The names of indices are the key to the problem. It seems they are processed in alphabetical order. Only the first one is taken into consideration so if you can rename your indices to have the one with keys first then you should get unblocked.
QUESTION
I want your suggestions to start a simple software developement. I'm an intern student and i want to build, preferably, something that can be acceced with a user authentication to a specific number of users < 5 so that each one of them can access the analysis of the data that concerns him. Preferably :
- I want my users to get to the app through the browser
- The users are those who will provide data to the app through an upload file button so this latter can output the whole analysis
- the app should have a professional look
I'm supposed to work with these four-five peapole to determine what they want to see so i can prepare all the analysis code that corresponds to the right feeded data. genrally the data will have csv excel format.
I've start working with R shiny then I built a single shiny app for control and mangement director that contains a dahsboard with analysis/viZ elements. Then i figured out that I cannot add the feature of multiple users and neither the authotication feature. then I've start learning django but i realized that it's quite harder to do it in a month. I searched for django-plotly-library but I always hesitate to work and learn until the end.
well, now i'm open to learn anything that can solve this issue. I've been hesitating for a month to choose the right technology. I appreciate your suggestions and remarks.

QUESTION
How do i delete data from two tables in Android room using a transaction? I cannot have data be deleted from just one table, its both or neither. Both entities have 1 DAO each.
TimerDesign
is parent, IntervalDesign
is child
I have setup a parent - child class as i will need the 1:M relationship for this class later to get each parent with all its children, at present trying to delete one parent with all its children only deletes from the parent table.
...ANSWER
Answered 2021-Jun-14 at 12:49If you define a ForeignKey in the IntervalDesigns Entity the you can use onDelete = ForeignKey.CASCADE
. This will propagate deletion of the children when a parent is deleted and it's all done within the same transaction (so there would be no need for @Transaction
on either of the queries).
You can also specify onUpdate, however this would only propagate changes to the parent column (which is rarer).
See ForeignKey and perhaps also SQLite ForeignKeySupport
Your code would be something like :-
