kandi X-RAY | Warden Summary
define "health checks" for your applications, resources and infrastructure. keep your warden on the watch. warden is a simple, cross-platform library, built to solve the problem of monitoring the resources such as the websites, api, databases, cpu etc. it allows to quickly define the watchers responsible for performing checks on specific resources and integrations to easily notify about any issues related to the possible downtime of your system. each watcher might have its own custom interval. for example you may want to check e.g. the api availability every 500 milliseconds, while the database should respond only every 10 seconds and so on. or you could just set the common one interval (5 seconds by default) for all of the watchers.

QUESTION
This is my first time working on Adding a back-end with Active Admin. The user side of my rails app http://localhost:3000/colleges is working fine but in my admin section http://localhost:3000/admin/colleges it's bringing up the following error. I have tried some solutions from stack overflow but no answer is relating to my error so far.
...ANSWER
Answered 2022-Mar-13 at 14:18I had disabled config.active_record.migration_error = :page_load
in config/environment.rb
file, hence pending migration error could not be shown.I ran rake db:migrate:status
and some of my migrations were pending. I figured out the error was being caused by the ratyrate gem and I fixed using the following solution Ruby on Rails: ratyrate gem table already exists?.

I am getting this error when I try to sign up a user. After this error, I'm still able to sign in with the user it would've created, but it always shows me this upon registration. Please let me know if there's other information you need. Been stumped on this for a few days.

Answered 2022-Jan-03 at 12:08This seems to a be a known issue with Rails 7 and Devise now. To fix it in the meantime simply add the following line to your devise.rb.

I need to query XML documents using XPath expressions in a Java application. I have created the following classes, which accepts a file (location of the XML document on a local hard drive) and an XPath
...ANSWER
Answered 2022-Jan-07 at 01:47Your XML is not namespace-well-formed: It uses undefined namespace prefixes.
First fix your XML. Then fix your getNamespaceURI()
method to return the right namespace URI for each used namespace prefix.
See How does XPath deal with XML namespaces? for an example of a working getNamespaceURI()
method.
QUESTION
I've managed to consistently reproduce a deadlock situation (I believe) despite following the following resources:

- https://github.com/rails/rails/issues/27025#issuecomment-260169414
The following code will deadlock:
...ANSWER
Answered 2022-Jan-04 at 02:45Okay, I figured it out.
It seems that this is an issue with the Zache gem. See this line:
https://github.com/yegor256/zache/blob/master/lib/zache.rb#L206
This I believe introduces an external sleep.
I was able to fix my code by wrapping the method BEFORE called zache.get
Something like this:

QUESTION
I have a Rails 6 website running on Elastic Beanstalk (Amazon Linux 2). I successfully implemented a process to use Certbot to generate an SSL certificate, and when I visit my website everything is working correctly. However, when I try to log in to my user console (using Devise), I receive 422 errors.
Rails Production Log
...ANSWER
Answered 2021-Nov-26 at 18:55If you are going to use ssl then using certbot is an ok solution to use but you should no longer serve http requests so you need to set your server block that listens on port 80 to redirect to an ssl block i.e. a block that listens on port 443. This doesn't look like it is setup to act as a reverse proxy to your rails server either, there should be puma or unicorn or whatever rails server you are running declarations. so none of this really makes sense.
You have a few options set in your config that I am unfamiliar with plus you seem to have the sites_available options mixed in with the nginx.conf file, this is ok but it is not a normal nor very configurable setup, however, because of the few options you have that I am not familiar with I'm not going to comment on your options, I'm just going to make a suggestion that you tidy up your server blocks so that the block listening on port 80 redirects to the port 443 block. You will need to open up your firewall to allow port 443. If using ufw then there is an nginx app you can set otherwise I'll leave you to figure out or ask in a different question how to setup your specific firewall for SSL on port 443.
Anyway, besides the above you should change your port 80 http block to look like this

QUESTION
I have a parameters
module in my project which other modules are dependent on. I'd like to write instegration tests for this module in separate manner. This module is a spring based one and has some db related logic, though db migration scripts are not available in this module since it is something that is out of its area of resposibility. By the way in-memory H2 instance is used for testing purposes.
What I'm trying to achieve is to make spring/hibernate create DB tables based on single @Entity
class present in this module, it is called ParameterEntity
.
It is defined like this:
