Heyy ^^ I'm coding a selenium program, but I'm stuck in one place. This program is made to buy 1 graphics card, on a French site, for my son's birthday. So there you have it, I coded everything but now my concern is that the web page of this graphics card is only available when it is in stock so the program cannot find the button by xpath "add to cart" . So I had the idea to make a loop so that as long as the "add to cart" button is not available, the program opens the page of the graphics card to infinity (like this when it is available, the button appears and the rest is done). However, I don't know how to achieve this condition, this loop, can you help me? I am on selenium with webdriver

I am a python developer, but there is a small part that I need to complete in Javascript, I am unable to figure it out.
This needs to be done in a local computer only. I have a .csv file with two columns, and I Need to make a real-time line chart (it reads csv file every X seconds and refresh).
I tried some code from online, they work only with real url. My file is local, so I get this error in all the code I tried by copy/pasting.
Access to XMLHttpRequest at 'file:///C:/Programs/Stock/test.csv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https.
It would be great, If someone can help me with this, otherwise I need to learn Javascript from scratch.

when the page load for the first time with API request it errors out. but after page load if I put the same code back it works fine. Can someone please help what am I missing here. Or show me the trick to delay the page loading until data loads from api
...ANSWER
Answered 2021-Jun-15 at 04:27Your productData is initially null and will be on any subsequent renders until updated by the GET request. Attempting to access the productData.variants throws the error because productData is null.
You can use some loading state and conditionally render your UI. Use a null-check/optional chaining operator on the productData state.

ANSWER
Answered 2021-Jun-10 at 20:49You should deffinitely use a cloud function to update the stock. Create a function onCreate and onDelete functions trigger. If users can change data you would also need to onWrite function trigger.
Depending on the amount of data you have you woould need to create a custom queue system to update the stock. Belive me! It took me almost 2 years to figure out to solve this. I have even spoken with the Firebase engeeners at the last Firebase Summit in Madrid.
Usualy you would use a transaction to update the state. I would recommend you to do so if you don't have to much data to store.
In my case the amount of data was so large that those transactions would randomly fail so the stock wasn't correct at all. You can see my StackOverflow answer here. The first time I tought I had an answer. You know it took me years to solve this because I asked the same question on a Firebase Summit in Amsterdam. I asked one of the Engeeners who worked on the Realtime Database before they went to Google.
There is a solution to store the stock in chunks but even that would cause random errors with our data. Each time we improved our solution the random errors reduced but still remained.
The solution we are still using is to have a custom queue and work each change one by one. The downside of this is that it takes some time to calculate a lot of data changes but it is 100% acurate.
Just in case we still have a "recalculator" who recalculates one day again and checks if everything worked as it should.
Sorry for the long aswer. For me it looks like you are building a similar system like we have. If you plan to create a warehouse management system like we did I would rather point you to the right direction.
In the end it depends on the amount of data you have and how often or fast you change it.

QUESTION
I have 5 different tables:
- Toasters: product name (foreign key to products and primary key), slots, serial
- Microwaves: product name (same as toaster), wattage
- Products: product name (primary key)
- Stock: product (fk to product), warehouse (fk to warehouse), amount
- Warehouse: name (primary key)
toasters and microwaves are child tables of products (although its not using postgres inheritance, since there are issues with it). They represent different models of toasters (simplified to just slots and wattage here). Every toaster and microwave has exactly 1 entry in the products table.
Now the goal is to create a query that essentially gives me an amount of all products across all warehouses for a given list of product names. The problem is, that some warehouses may not have a stock entry for a certain product. They also have either one stock per product or none.
I have managed to make it work for a single warehouse:

Install stock
You can use stock like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
