I think you may be missing the fact that there is no error in the given example, therefore the rule of applying the template that occurs last in the stylesheet is not invoked. You can verify this by switching the order of the templates and observing that the result remains unchanged.

There is no error because the identity transform has a priority of -0.5 while the specific templates have a priority of 0.

Python function that iterates a menu of three lists of strings issues

Asked 2021-Dec-27 at 15:10

I have to write a function that takes three dishes and an ingredient and outputs true if the ingredient isn't in the dish and false if any of the dishes contain the ingredient.

I've been trying this for hours and initially was having an issue where it was either outputting true or false for all test cases regardless. I have now tried using any() but its returning a TypeError: 'bool' object is not iterable and I'm getting really confused and frustrated.

any advice would be much appreciated.

QUESTION

Cosmos Write Returning 429 Error With Bulk Execution

Asked 2021-Sep-01 at 20:25

We have a solution utilizing a micro-service approach. One of our micro-service is responsible for pushing data to Cosmos. Our Cosmos database is using serverless provision having a 5,000 RU/s limit.

The data we are inserting into Cosmos looks like the below. There are 10 columns and we are pushing a batch containing 5,807 rows of this data.

Id CompKey Primary Id Secondary Id Type DateTime Item Volume Price Fee 1 Veg_Buy csd2354csd dfg564dsfg55 Buy 30/08/21 Leek 10 0.75 5.00 2 Veg_Buy sdf15s1dfd sdf31sdf654v Buy 30/08/21 Corn 5 0.48 3.00

We are retrieving data from multiple sources, normalizing it, and sending out the data as one bulk execution to Cosmos. The retrieval process happens every hour. We understand that we are spiking the Cosmos database once per hour with the data that has been retrieved and then stop sending data until the next retrieval cycle. So if this high peak is the problem, what remedies exist for such a scenario?

Can anyone shed some light on what we should/need to do to overcome this issue? Perhaps we are missing a setting when creating the Cosmos database or possibly this has something to do with partitioning?

ANSWER

Answered 2021-Aug-30 at 23:00

You can mostly determine these things by looking at the metrics published in the Azure Portal. This doc is a good place to start, Monitor and debug with insights in Azure Cosmos DB.

In particular I would look at the section titled, Determine the throughput consumption by a partition key range

If you are not dealing with a hot partition key you may want to look at options to throttle your writes. This may include modifying your batch size and putting the write operations on a while..loop with a one second timer until RU/s consumed equals 5000 RU/s. You could also possibly look at doing queue-based load leveling and put writes on a queue in front of Cosmos and stream them in.

QUESTION

How can I render different sets of data into one React component multiple times?

Asked 2021-Sep-01 at 19:02

I have data sets for recipes that I want to map onto cards that are on a carousel that I made.

I am trying to do this the most efficient way with least amount of code, I am already achieving it by just creating multiple sliders for each set of recipes. However I want to make it so I only need the one slider component, which already has the card component in it - in which I can then map my data into as I need. Rather than just having several of the same components where I have already mapped each dataset into previously.

Code below will show what I am trying to do.

Also here is a code sandbox if you go to the menu section and click on pasta option then the seafood button at top it will show the issue I have currently of my method of mapping is not working.

for reference this has been designed mobile first so UI will only look normal when in mobile dimensions.

The Problem you have here is , you are telling the Slider upfront that you are going to render a certain list of items. Due to this we are repeating the Slider logic in all the places where ever we want to achieve the carousel behaviour.

But what we need is for the slider to render it contents dynamically because slider doesn't care what it needs to render. All it needs to do is provide the carousel behaviour. This in react can be achieved using the children prop.

Create a new component for the Slider,

You are setting the ingredients state as a string, so you are basically 'stringify' a string which will result in JSON SyntaxError. If you want to send an array that way you must specify the array bracket [ and ] in order to make it a valid array.

QUESTION

Resetting an array after a loop

Asked 2021-May-08 at 23:40

I've written some JavaScript function (selectMeal) to loop 7 times randomly selecting 1 item from an array (tempMealList) then push the item to another Array (dinnersPicked). Once the items been added to the new array (dinnersPicked) it's then removed from the original array (tempMealList) to avoid it from being selected again.

In the console, each run of this function (selectMeal) yields no issue, but when I trigger the function on a button click in HTML, each time the buttons clicked the array being used seems to be permanently altered, with the items randomly selected on the first run of the function not being considered on the second click and similarly for any successive click, any item previously shown is not considered.

I've tried to resolve this in the function by redefining the variables at the start of the function to reset the array being considered on each click but this doesn't seem to work.

What am I doing wrong and how can I make sure that with every click the original array is considered?

Here is the code:

ANSWER

Answered 2021-May-08 at 23:40

When you do let tempMealList = mealList; those two variables are now pointing to the same array. So when you do tempMealList.splice(index,1) you are also modifying mealList.

Try let tempMealList = [...mealList]; instead to make a copy.
