QUESTION
Attempt
After reading a large json file and capturing only the 'text'
column, I would like to add a column to dataframe and set all rows to a specific value:
ANSWER
Answered 2021-Feb-19 at 04:23The problem is that your read_json(....).text
line returns a series, not a dataframe.
Adding a .to_frame()
and referencing the column in the following line should fix it:
QUESTION
My web-application suffers from duplicate payment transactions. It uses Payflow Pro JAVA SDK to make a call to PayPal Gateway to process users payments via PayPal.
As, a short term solution, we decided to pass INV NUM
, as suggested in this article, so PayPal can track it and reject the transaction with the same invoice ID with corresponding error code and message.
While testing the fix I am still getting statusCode
0 and transaction message APPROVED
for the duplicate transaction. However for the duplicate transaction, the DUPLICATE
flag is set true which I believe identifies it as duplicate one, but I don't understand if it means that the transaction was not processed successfully, meaning user was not charged second time.
The invoice generation method looks like this:
ANSWER
Answered 2021-Jan-20 at 14:59After, having chat with PayPal tech support and digging deeper into PayPal documentation, I got an answer to my question. The unique INV NUM approach doesn't work in my case of integration with PayPal. Instead to fix a problem, I need to generate and set unique Req Id for the transaction. More details about X-VPS-REQUEST-ID header is here. The PayPal stores the received request ID in the request table, so when you send a new transaction it will check if such request ID was used before, if yes then it will treat the transaction as a duplicate and return you response of the original transaction:
Important: If you send in a NEW transaction with a previously used X-VPS-REQUEST-ID, the server ignores the new data and returns the response to the original transaction associated with that X-VPS-REQUEST-ID.
The duplicate transaction will have flag DUPLICATE
set to 1
.
Such behavior, requires me to handle additional case, when the original transaction failed because of invalid card expiration date for example, and second transaction was sent with valid expiration date. In such case, I have to generate new req ID, as otherwise I will still be getting failed response from the original transaction.
NOTE: putting responsibility on the payment vendor is only an additional measure against duplicates and should not be considered as the primary solution for a problem. That is why I have to redesing my payment workflow to determine duplicate transaction before making a call to the payment vendor and handle it in a proper way.

I am trying to migrate my current project to android x and this exception shows up
...ANSWER
Answered 2020-Nov-05 at 00:31by using gradlew build --debug I was able to get the specific cause which was causing this issue it was caused by
apply from: '../config/style.gradle'
which is a tool development tool to help programmers write Java code that adheres to a coding standard.

I didn't reset it but temporarily disabled it as my requirement was to migrate to android x.
QUESTION
I am reading up on IndexedDB (on developers.google.com and MDN). From what I gather, the usual pattern for doing practically anything is
- create a request object,
- add onsuccess, onerror and perhaps more callbacks
- there's no 3.
The request then eventually does its thing and calls one of my functions (or settles a promise, if the wrapper is used). I'm missing some kind of commitment step. Given that the fulfillment of the request is asynchronous, does this mean it can happen on a different thread? If so, what if it is really quick (or my code really slow) and manages to terminate between 1 and 2 before I've set my callbacks?
Or is it that the requests will run on the same thread in idle periods? If so, I can imagine it happening that I overwhelm the request queue (say on a very low-profile device). How that would be signalled if callback is not an option (my function is still running)?
...ANSWER
Answered 2020-Apr-15 at 17:40A write request such as put or add appends work to be done to the transaction on which it was created. A write request commits when its transaction commits. A transaction commits shortly after detecting there are no more requests to process.
It is a bit more complicated regarding what it means to commit, as I think Firefox and Chrome have different meanings, or did at some point in the past, where Chrome committed in memory and later flushed to disk, but Firefox did not commit until flushed to disk, or its backwards, sorry. Flushing to disk however might be pedantic/arbitray so I would not worry about this distinction. Especially if you are unfamiliar with things.
To detect when a transaction commits, listen for the complete event of the transaction.
To detect when a transaction rolls back due to an error and does not commit, listen for the error event of the transaction. There is also a weird note here, transactions do not possess an error property, only requests do. So the error event at the transaction level will correspond to the error from one of its requests.
To detect when a transaction finishes either successfully or not, listen for both the complete and error events.
JavaScript is single threaded. indexedDB manages threading and so forth for you. You do not need to worry about threads.
If your really slow code terminates during a request, the transaction will not complete successfully. The database will be in the same state as it was prior to starting the request, as if the request never happened.
If your really slow code terminates after the first request has completed but before a later request has completed in the same transaction, then the transaction will not complete successfully. A transaction only completes successfully when all of its requests complete successfully. Therefore the database will be in the same state as it was prior to starting the first request, as if if none of the requests in the transaction occurred.
If indexedDB is unable to fulfill a transaction due to some kind of performance pressure error then the transactions in question essentially do not commit and there is no durable state change. This would be raised as some kind of more general JavaScript error, or performance permitting, just a normal transactional error.

QUESTION
I want to scrape the "data-price" from this url, but it is coming back undefined. Any ideas?
...ANSWER
Answered 2020-Mar-30 at 17:56When you do a request, the website returns some code which will processed by your browser. Some websites return javascript code which will build the page. It's your case. The website is returning some code which need a browser to process the java script and then build the HTML.
I don't know if axios can do that, but what you need is a headless browser. I suggest you Puppeteer.
A good tutorial here.
QUESTION
I am currently making a database table that separates a comma-separated list of tags from one table to a table containing every unique tag in the first table. Ultimately, this will be used to create a table where every tag is joined with every id that has it. I have created a procedure that separates a list of values based on commas and inserts each value into a table:
...ANSWER
Answered 2020-Mar-21 at 09:33I had to rewrite your try. Your iteration loop gave errors, so i changed the code to remove the first added value
Further I added a cursor for RawRecipes because i beleive you want to add all the tags from every row.
you should should think about reduce the procedure, to a Input parameter that will split the tags, and call it in a AFTER INSERT TRIGGER, so that when you insert a row into RawRecipes the tags where automatically added
Then of course you should also check in an AFTER UPDATE Trigger if tag in RawRecipes has changed and then call the procedure, that separates the words

As Edward

ANSWER
Answered 2019-Apr-07 at 07:35The problem I created for myself was totally messing up the shapes of my distributions. What I failed to properly grasp at first was that the current_state
of my tfp.mcmc.sample_chain
should have been scalars (shape==()
) that represented the initial positions of the chains. Once I realized this, then it became clear that those positions, q_mu
and q_t
had quite the wrong shape and should be the mean of samples from the positions determined from the data
QUESTION
I am working on an e-commerce site and the product images are NOT visible on the live site but they are visible on my local development version even though I am using an exact copy of the code and database. What is even weirder is that when I open the developer console and look at - the source code for the images is there and also the preview of the image is correct which tells me that the image is loaded correctly it must be something else.
Also, the only difference between the development site and the live site is that the live site runs on SSL, so I guess the problem could be related to that but I have no idea what it could be - the image urls start with https
.
Here is an example page where the images are not visible.
Also, to mention the website is build with WordPress and WooComerce, custom theme.
EDIT: For some reason the images are no longer visible on the local version as well.
...ANSWER
Answered 2018-Jun-05 at 14:42One of the parent elements / ancestors of the image (in single product view) is a DIV which has the class
attribute woocommerce-product-gallery woocommerce-product-gallery--with-images woocommerce-product-gallery--columns-4 images
and a style
attribute which contains opacity: 0
, i.e. completely transparent, therefore it remains invisible
So you have to find where that opacity setting is added and deactivate it. (Or if it's static, simply remove it from the HTML tag)
