QUESTION
I'm using React Hook Form v7 and I'm trying to make my data form persistent on page reload. I read the official RHF documentation which suggests to use little state machine and I tried to implement it but without success. Is there a better way to do it? However...
The first problem I encountered using it, is that my data is a complex object so the updateAction it should be not that easy.
The second problem is that I don't know when and how to trigger the updateAction to save the data. Should I trigger it on input blur? On input change?
Here's my test code:
...ANSWER
Answered 2022-Mar-19 at 23:41The state itself won't persist any data on page reload.
You need to add your state data to Local Storage.
Then load it back into the state on componentDidMount (useEffect with empty dependency array).
QUESTION
My question is about what should be the most OOP solution and the right design pattern for my situation. We have a user entity and multiple account entities belong to the user. Account entities can have multiple states and we can execute multiple operations on accounts. The outcome of these operations is based on the account entity's state.
I have the following code which is based mostly on switch (sometimes it looks like a few "if"). I would like to change it but cannot find the right design pattern.
...ANSWER
Answered 2022-Mar-13 at 20:41If I understood question correctly, then it is necessary to apply some action by its state.
If it is true, then we can use Factory pattern to get desired object which can execute some action. Mapping between state and action can be putted into HashTable.
So let's see an example of code. I will write via C#, but this code can be easily translated to Java because languages have many syntax similarities.
So we will have enum of statuses:

I have been able to use awscli to get start the execution but I need to be able to know when is completed or result is success before it can go to the next step in the pipeline.

QUESTION
I am using little-state-machine (https://github.com/bluebill1049/little-state-machine) with react-router for a wizard on a client's site and I need to reset the store when a user returns to the wizard landing page. I followed this answer in stack overflow (React Little State Machine clear data) but I can’t get it to work. I can’t show the full application, but from the below can you see anything wrong with what I have done.
App.js
...ANSWER
Answered 2022-Feb-23 at 16:17From what I can see of the code snippet you've shared you are it appears as though this Steps component is possibly rendering a Route or set of Routes corresponding to the wizard steps. If I understand your question/issue you want to reset the wizard any time the the step is 0 or some falsey value.
The issue is that Steps only runs this check once when it mounts. To resolve you can add the location object as a dependency to the useEffect hook so the hook's callback is triggered any time the location changes. The step condition will check if on the wizard landing page and reset the state machine.
QUESTION
I am creating and running a task on my ECS fargate cluster.
Task definition (with role) and fargate cluster is already created.
When I use run task step in step function, I am getting following error,
...ANSWER
Answered 2022-Jan-09 at 07:56Because your task will use an IAM Role, you need to specify the additional permission 'PassRole'.
The best practice is to restrict which roles can be passed. So is recommended to add a condition limiting to only allow to pass roles to ECS tasks.
Try adding this statement to your policy:
QUESTION
Apologies for the convoluted title!
I'm new to rust, and I'm trying to solve a very specific problem. None of the solutions I've tried so far seem to work nicely within the language bounds.
I have a struct that contains data (called Model), and it also contains a dynamic Box for a "strategy" struct. There are several different strategy structs, and they are identified by a common Trait (Strategy) that each contain a separate way of modifying the model through their "execute strategy" method. By doing this, the I can dynamically change which strategy is used by changing the model's strategy instance like a state-machine.
Each strategy is immutable, but they mutate the model's data. They do sometimes contain their own immutable data, so enums seemed like an awkward fit.
...ANSWER
Answered 2022-Jan-01 at 07:38I don't know what's the most idiomatic way to solve this, but I can think of a few. One method would be to remove strategy from self so it's not a member of self during the operation, then put it back afterwards. This seems like an anti-pattern since you can forget to put it back afterwards (especially if you forget to handle an error):

I built a multistep form using react-hook-form with a dynamic fields array using useFieldArray.
Documentation: useFieldArray documentation
Here is the full working code link: React Multi-step form with useFieldArray
In the 2nd step when I add new fields using add a dog button, everything works fine, the new data of step is saved to localstorage using little state machine.
But when I click the previous button, the added fields disappear whereas data is still in localstorage.
code for 2nd step:

Answered 2021-Nov-12 at 10:55It's very long but maybe we can figure it out.
The use is correct, the problem in my opinion is that you're not checking the state and just printing the default values everytime

QUESTION
I have a AWS SAM template that creates a API Gateway hooked into a Step Function.
This is all working fine, but I need to add a Integration Response Mapping Template to the response back from Step Functions.
I cant see that this is possible with SAM templates?
I found the relevant Cloud Formation template for it: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-apitgateway-method-integration-integrationresponse.html
But It looks like I would have to create the whole AWS::ApiGateway::Method / Integration / IntegrationResponses chain - and then I'm not sure how you reference that from the other parts of the SAM template.
I read that it can be done with openAPI / Swagger definition - is that the only way? Or is there a cleaner way to simply add this template?
This is watered down version of what I have just to demonstrate ...
...ANSWER
Answered 2021-Oct-22 at 06:58Right now you're using AWS SAM events in your state machine to construct the API for you, which is a very easy way to easily construct the API. However, certain aspects of the API cannot be constructed this way.
You can still use AWS SAM however to construct the API with all the advanced features when you use the DefinitionBody attribute of the AWS::Serverless::Api (or the DefinitionUri). This allows you to specify the API using the OpenAPI specification with the OpenAPI extensions.
You still need to define the event in the StateMachine though, since this will also ensure that the correct permissions are configured for your API to call your other services. If you don't specify the event, you'll have to fix the permissions yourself.
