My chainlink request isn't getting fulfilled?

Asked 2021-Jun-16 at 00:09

Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).

Same contracts (different addresses), same function call.

Assuming what I mentioned in my comment on your question, the fix is just to simplify your FieldWithConfidence type significantly. Right now it is trying to add a number of additional levels of structure beyond what you seem to want. Here is a version of that type that works as I think you intend:

This is happening because there is no Transaction opened in DTO(object become detached). Wherever you have fetched the object from the DB call contractFile.getContract() so that the ORM framework loads the lazy-loaded object.

After thinking a little bit, I think I know what your problem is, you are using function ($keywords), but you should be using function () use ($keywords) because, in the source code, you see that it is doing $value = $callback(), but your function is awaiting $keywords, if you want to share a value, you have to use use ($keywords) again, like your second function in the where.

So, it should be:

Delete from a table where the id of user is equal to the id on another table where user email

Asked 2021-Jun-12 at 19:39

I'm looking how to delete something from a table where the result from another query on another table.

I need to delete from "contract" where id is equal to the id of the user, where the email is equal to email@gmail.com.

Something like " DELETE FROM contract WHERE user = (SELECT id FROM users WHERE email = 'testuser****@mailinator.com') "

So I can delete all the contracts from user 3 but without using it's id because I just know the email. (I seed the testusers with a script so I have the email but no the id)

Cant stop Docker/Vmmem from running

Asked 2021-Jun-12 at 06:15

not so long ago I started to practice with writing EOS smart contracts on my windows 10 computer. For this I needed to install among others, a Linux subsystem for Windows and Docker. In the last couple of days I noticed some pretty significant performance issues, when looking for the perpetrator in my task manager I came across Vmmem using up 1.8 GB of ram (which is quite a lot considering I have only 8GB on my laptop):

I Googled around some and figured out that this program handles virtual machines and such, and with that Docker. I don't have Docker Desktop or Ubuntu opened at the time of this screenshot, turned off the setting "Start Docker when you log in" and restarted my computer, but still this program is hogging up my RAM. As you may understand, it isn't worth it for me to keep this running in the background considering this EOS Development is a side-thing for me, hence I don't need to use Docker often. I would deem it a shame if I had to give up on this 'hobby' for performance issues so any help would be appreciated.

Probably it is very old example - it uses http but modern pages use https - and amazone could rebuild page and now it has better system to detect spamers/hackers/bots and block them.

If I use @url http://toscrape.com/ then I don't get error 503 but I still get other error FAILED because it needs some code in parse()
