...ANSWER
Answered 2021-Jun-15 at 13:55Have a go with this

- I do string comparison, it works on same length strings. No need to create new dates for the time
I am not sure where you will pass the user time

QUESTION
I am trying to deploy 2 containers on 2 different tasks (1 container per task), one is my frontend and the other is my backend server. I am trying to figure out how to configure the communication between them.
I saw that a load balancer in a service is a good option. However, should I configure load balancer for my front end server and another one for my backend? Meaning each time I have public-facing services and private services I need 2 load balancers?
I would like to only expose my front-end to the public internet and my backend will remain private (although I make API requests to the outside world - probably need to configure outbound route too?).
I would highly appreciate any information.
...ANSWER
Answered 2021-Jun-15 at 09:03No you don't need a private LB for that. It is an option you can use but ECS has since introduced the concept of Service Discovery for back-end services. The idea is that your front end is exposed to your users via a standard LB (e.g. ALB) but services that are being called by the front end and that run behind the scene can be addressed using this service discovery mechanism (based on Route53/CloudMap).
You can see an example of this concept here. This CFN template gives you the details re how you can build this layout.
QUESTION
The situation:
I am using React in the front-end and a Flask api server. I am wanting to send the data from React to the api and once I have done this I would like to use WTForms to run validations on the data before handling it. The question may seem similar to CSRF Protection with Flask/WTForms and React , but this does not answer the question, please take a look through I have put a lot of effort in writing a good question.
What I have
Currently the data is being sent successfully as a json object, where the keys match the names within the wtform structure, the aim is to get wtforms to take that json data and insert it into the object and and handle from there as normal
The JSON object being sent

QUESTION
I use datatablejs server-side in my MVC project. When I click to a column it sends the column name to server and I take the column name after all I order the table.
But the problem is in a table I don't want to order a column by server-side. I just want to order this column in front-end. How can I do that?
Here is some code:
...ANSWER
Answered 2021-Jun-14 at 13:36I get a link how to solve my problem.
here is the link: Problem Solved here
The solution is: When we get the table's data from the server, we can disable the server side processing temporary.
QUESTION
We are trying to automate an application with the Angular front-end and the ngx-Boostrap css framework. Is there any way to know if an application can be automated with Selenium or not?
I ask this, because we are having some difficulty in locating the elements. I talked to a colleague and she asked me to test it first with Selenium IDE, in case it worked, the application could be automated with Selenium WebDriver. That's true?
...ANSWER
Answered 2021-Mar-08 at 21:33Yes you can. Selenium uses the html and css of your page to interact with and automates browser behaviour. If your app run in the browser, you can use selenium to automate it.
To make this easier, and more stable, I would recommend certain things as you build the app: Make sure you add either Id's or test-data attributes to your elements.
Use classes to manipulate styling, and use these for any and all important elements you want to interact with. Bootstrap and angular are no objection for this in any way. Then it should be easy to locate your elements, and your test code will be much cleaner and better maintainable.
Wheter you want to use selenium wrapped in something like protractor, codecept, use it with java, javascript python or whatever, are just choices. All of them work, whatever you know best, whatever the developers as a team know best so you can easily work together would be my recommendation.

QUESTION
I am trying to create an arm template that creates an additional subnet on an existing Vnet and also creates the NSG at the same time and then attaches it to the subnet. I have got it to the point the NSGs are created but the minute I try to attach NSG to multiple subnets it fails to create the subnet and NSG. Error below
...ANSWER
Answered 2021-Jun-12 at 17:51You have a "mode": "Incremental"
property on a resource 'subnetname1'. subnet does not take a mode parameter - see the reference: https://docs.microsoft.com/en-us/azure/templates/microsoft.network/virtualnetworks/subnets?tabs=json
However, when deploying virtual network, be aware of an well known problem - you need to specify subnets as a property of a vnet. Although you have option do deploy a subnet resource, when you run your template for the second time, virtualNetwork resource will try to remove all subnets (because property subnets is empty) - see more here: https://github.com/Azure/azure-quickstart-templates/issues/2786
