serv | A development server for serving static files | HTTP library

I solved my issue by using Docker Compose Wait. Essentially, it adds a wait loop that samples the DB container, and only when it's up, runs migrations and seeds the DB.

My next problem was: those seeds ran every time the container was run - I solved that by instead running a script that runs the seeds, and touchs a semaphore file. If the file exists already, it skips the seeds.

I was able to fix this by removing sub_filter directive from nginx conf and updating url_prefixes in flask app. The steps I took are posted on this dash forum

Starting from version 0.5 of Rocket, you are not expected to use rocket_contrib, because this one was split into features which are either already in the core crate or moved to separate crates. The notes from this revision (see also issue 1659) provide a few more details:

This follows the completed graduation of stable contrib features into core, removing 'rocket_contrib' in its entirety in favor of two new crates. These crates are versioned independently of Rocket's core libraries, allowing upgrades to dependencies without consideration for versions in core libraries.

'rocket_dyn_templates' replaces the contrib 'templates' features. While largely a 1-to-1 copy, it makes the following changes:

• the 'tera_templates' feature is now 'tera'
• the 'handlebars_templates' feature is now 'handlebars'
• fails to compile if neither 'tera' nor 'handlebars' is enabled

'rocket_sync_db_pools' replaces the contrib 'database' features. It makes no changes to the replaced features except that the database attribute is properly documented at the crate root.

In short, you will need to migrate your code away from rocket_contrib. Better guidelines may become available once v0.5 is definitely released, but until then, you may look for the features once available in rocket_contrib in the core documentation and respective Cargo feature list.

I had the same problem and I found a workaround here at https://github.com/jekyll/jekyll/issues/8523

Add gem "webrick" to the Gemfile in your website. Than run bundle install

At this point you can run bundle exec jekyll serve

For me it works!

the solution was to use the website URL in both settings; for the cors origin address in the backend and for the socket creating in the front end so

In a non-SwiftUI situation, I'd normally recommend making player an optional and loading it later, but, as you've probably discovered, you can't make an @ObservedObject or @StateObject optional.

I'd recommend refactoring AudioPlayerAV so that it does the important work in a different function than init. That way, you're free to load the content at whatever point you want.

For example:

i was able to resolve the same issue by downgrading firebase to firebase@7.12.0:

Java does not have the "retain cycle problem".

This problem exists for systems that use reference counting, which the Java GC does not use.

Therefore in Java the WeakReference class has nothing to do with those. It's simply a way to hold on to a reference to something while also not preventing it from being garbage collected

In other words, you can use it to remember an object as long as something else (strongly) references it.

This functionality is quite similar to what the weak keyword does in Swift. However, as described above, reference cycles don't stop objects from being collected in Java, so WeakReference is not needed in this specific case.

This SO question lists some practical uses for weak references and this question discusses uses specifically in an Java/Android environment.
