inventory | Ruby gem that allows programatic access | Business library

In your logs, we can see the following error:

This solution should work:

Loop the product and search the joined patterns. All matches will be added to the new list. For example, given the abridged data

it is possible that your inventoryS.currency is a string value

A few errors but

A unique pointer is exactly that: unique. There is only supposed to be one unique pointer to each object. As soon as you try to return the unique pointer, there would have to be 2: one in your vector elements and one returned from your function. There are ways around this I think, like returning a reference to the pointer, but that gets messy quickly.

You can create a shared_ptr from a unique_ptr, or you can just use a shared_ptr in your vector to begin with.

Alternatively, in the case of an inventory system you're working with relatively simple objects. In my experience you'd want one class for the items in the actual game world, and a separate InventoryItem class for items that are stored in an inventory.

Each item then would store the type of inventoryItem it constructs. This not only means you don't have to mess with all the ins and outs of making sure inventory items don't show up in your gameworld, it also means you can easily pass those items by value if it's more convenient, because the amount of actual data in such an item is laughably small :)

At the end of the day it's really a personal choice how to manage your pointers, or if you should use pointers at all. Only a unique_ptr wouldn't be used according to its purpose here.

Try this:

I don't think any other straightway to update the specific index position element using aggregation pipeline,

• $range to generate array from 0 to length of materials.m1.inventory array
• $map to iterate loop of above range array
• $cond to check current element is 0 then go to update part otherwise return element from materials.m1.inventory by input index
• $arrayElemAt to get specific element from materials.m1.inventory
• $mergeObjects to merge current object with amount updated property

gather_facts will be evaluted before the play loop has started so ansible cannot know which group/host var it should load in this case. The problem is exactly the same for the connection attribute.

I only see one way to fulfill your requirement by gathering facts explicitly and setting the connection for each host. Ini format does not play well with this for the inventory so I transformed to yaml. I also modified your default hosts expression in playbook so that it directly get the host name from inventory. You can keep yours if it suits your needs if you wish.
