R Shiny DT callback to update column filters not working as expected with multiple tables

Asked 2022-Mar-22 at 15:29

I've been working on a callback function for an R Shiny datatable from the DT package. The expected functionality is that when you use the column filters to change what rows are present in the table, the other filters should only show the options actually present in the table rather than those from the original dataset.

In the example below, you can view this behaviour. In the first table, set the N column to 0, the P column to 1 and the K column to 0 and then click the filter in the block column and you'll see it only shows the 2, 3 and 4 as expected.

The problem arises when I attempt to pass this same callback function to the table below it. I can't seem to figure out whats going on. The callback function (to my knowledge) is performing all of its actions relative to the table parameter given to the callback function.

I would appreciate any help on this. Thank you!

See the feedback on https://github.com/rstudio/DT/issues/952#issuecomment-1024909574

It has nothing to do with DT's callback functionality. The cause of your issue is that you should have defined local variables in JS with var x = .... Defining variables without the var prefix leads to a global variable. So the two callbacks will share the same variable.

By adding three var before table_header, column_nodes and input_nodes fixes this case.

But this is not enough as the unique_values should be carefully handled as well or you would face other issues in other cases.

In line 456 (The line transferFrom() is being declared) you are setting its visibility external which can not be used in the contract.

What is Context.sol uses for in Openzepplin

Asked 2021-Aug-14 at 17:51

I'm new to solidity and trying to deploy a ERC20 token using openzepplin.There is one thing that doesn't make sense to me is the context.sol file. From the comment section it's seem like the main function of the context.sol is to implement a GSN compatible contract so instead of using msg.sender you use _msgSender()

...

ANSWER

Answered 2021-Aug-14 at 17:51

In this case, it's the same thing.

I believe that the OpenZeppelin devs implemented this function to make it more easily interchangeable if that's going to be needed. So if for some reason msg.sender becomes obsolete, it's just a matter of changing one line instead of multiple lines throughout multiple contracts (and possibly forgetting about some).

A similar situation has happened before, when tx.origin was prefered by some blockchain developers, but then it was deprecated (by the Solidity lang core team) in favor of msg.sender.

Solidity - TypeError: Overriding function is missing "override" specifier

I am creating a Smart Contract (BEP20 token) based on the BEP20Token template (https://github.com/binance-chain/bsc-genesis-contract/blob/master/contracts/bep20_template/BEP20Token.template). The public contructor was modified to add some token details. However all of the standard functions are giving compile time issues like Overriding function is missing.

** here is the source code **

ANSWER

Answered 2021-May-11 at 13:28

Constructor public () - Warning: Visibility for constructor is ignored. If you want the contract to be non-deployable, making it "abstract" is sufficient.

The warning message says it all. You can safely remove the public visibility modifier because it's ignored anyway.

If you marked the BEP20Token contract abstract, you would need to have a child contract inheriting from it, could not deploy the BEP20Token itself, but would have to deploy the child contract. Which is not what you want in this case.

...

ANSWER

Answered 2021-Apr-18 at 09:32

It's a visibility issue.

If you want to access the _baseURI property in a derived contract, you need to make it at least internal (it's currently private).

Which also means copying a set of contracts locally so that you can update the ERC721Metadata.sol and import the updated version (and not the remote version) from the other contracts.

The _setBaseURI() function alone can be overridden because it's visible from your contract.

Private functions and state variables are only visible for the contract they are defined in and not in derived contracts.

Cannot access private property in a derived contract.
