My app has many Fees. All Fees share the same attributes except a few here and there. Say I have this structure:

I'm trying to use array_filter to filter an array of objects, they share a common value which is warehouse_id.

I have several farmers and I would like to conduct optimization (profit maximization) for each of them in GAMS. I can do this for a single farmer, so my problem is how to iteratively make it works for multiple farmers.

I recorded the data in 3 different .csv files as follows (see code):

• 1 file that states how much resource the farmer allocates on his farm (resource_allocation.csv for a single farmer and resource_allocations.csv for multiple farmers)
• 1 file that states how much resource the farmer has at his disposal (resource_endowment.csv for a single farmer and resource_endowments.csv for multiple farmers)
• 1 file that states how much gross margin the farmer get (activity_gross_margin.csv for a single farmer and activity_gross_margins.csv for multiple farmers)

The following code does what I want for the single farmer case.

Suppose we want to write a function ifE that takes a boolean, two handler functions (producing results of different types but implementing the same type class c), and some postprocessing function that can handle arbitrary c's. In other words, we want to generalize this function over Show:

I wrote a parser and evaluator for a simple programming language. Here is a simplified version of the types for the AST:

For example. i have Feeds and Upload Components. also i have ImageFeedList component in Feeds, Upload Components

(Feed.js)

After googling lots of related answers and tries, I seemly have to seek help here. I have an angular application, one of its components named stock-subscribe, which is used to display the feeTypes that a customer subscribed. Within this component, I created another component, stock-addsubs, used to display the feeTypes that are not yet subscribed by this customer. enter image description here

Obviously, the two feeType lists can compose one whole list. From stock-subscribe, I can get an array, subscribedFeeIds, which holds all the ids of those subscribed feeTypes.

My requirement is to pass this array, subscribedFeeIds, to the stock-addsubs component so that I can filter out those yet unsubscribed feeTypes based on those ids of the array.

To my best understanding, the data passing from one component to its sub component should be a simple process and neither of two component html templates should be involved for my case. Of the many googled solutions, using @Output and @Input seems the simpler than event emitting. However, none can successfully pass the elements of the array in the sub component.

I can get the expected id list (subscribedFeeIds[]) from the stock-subscribe component, and all the rest code work fine so long as the array passed to the sub component is not EMPTY.

A rather theoretical question: Let's say we have some object in the backend (let's ignore what technology and language it is) and we want to move (or actually copy) it into JavaScript code on the frontend side during rendering the page.

The reason why I'm asking about JSON is that many backends have some kind of json-ify function that takes an object in this language and produces JSON string out of it. It's tempting to use that in this way:

I am trying to send the original flowfile as input to next processor, but ending up getting the error, I am very new to Nifi and also some experience in Java.
