There are two cases where the debug view does not show the error details
properly:
* When the cause is mapped to an HTTP status code the last exception is
unexpectedly uwrapped
* When the last error is thrown from a view template the debug view is
not using the `rescues/template_error.html.erb` to generate the view
Both the cases could be fixed by not unwrapping the exception. The only
case where the exception should be unwrapped is when the last error is
an `ActionView::Template::Error` object. In this case the HTTP status
code is determined based on the cause.
There are actually more wrapper exceptions that are intentionally
thrown. However, there is a consistent pattern of setting the original
message and original backtrace to the wrapper exception implemented, so
the debug view will not lose the information about what went wrong
eariler.
In this case statement, there are two patterns that start with the same
line:
when %r{/not_found}
...
when %r{/not_found_original_exception}
...
Because the string "/not_found_original_exception" does match the first
one, it is never routed to what it is supposed to be routed, causing one
of the tests for DebugExceptions to happen to be passing.
After changing the regex expressions back to strings, I noticed that the
test setup is not complete (the template object needs to be a proper
template object). Once I fixed it all the tests started padding.
The test passes an instance of `ActionController::Parameters` that acts
like a Hash but does not respond to some Hash methods like
`symbolize_keys`.
Moreover, if someone were to call `to_h` on the value it would fail since
the parameter is not permitted. So this is a great way to ensure that the
partial rendering pipeline does not mess with `locals`.
Allows aliasing, predications, ordering, and various other functions on `And` and `Case` nodes. This brings them in line with other nodes like `Binary` and `Unary`.
Currently `conn.column_exists?("testings", "created_at", "datetime")`
returns false even if the table has the `created_at` column.
That reason is that `column.type` is a symbol but passed `type` is not
normalized to symbol unlike `column_name`, it is surprising behavior to
me.
I've improved that to normalize a value before comparison.
That would allow us to test broadcasting made with channel, e.g.:
```ruby
class ChatRelayJob < ApplicationJob
def perform_later(room, msg)
ChatChannel.broadcast_to room, message: msg
end
end
```
To test this functionality we need to know the underlying stream name
(to use `assert_broadcasts`), which relies on `channel_name`.
We had to use the following code:
```ruby
assert_broadcasts(ChatChannel.broadcasting_for([ChatChannel.channel_name, room]), 1) do
ChatRelayJob.perform_now
end
```
The problem with this approach is that we use _internal_ API (we shouldn't care about `channel_name` prefix
in our code).
With this commit we could re-write the test as following:
```ruby
assert_broadcasts(ChatChannel.broadcasting_for(room), 1) do
ChatRelayJob.perform_now
end
```
- If you had a PORO that acted like a Numeric, the validator would
work correctly because it was previously using `Kernel.Float`
which is implicitely calling `to_f` on the passed argument.
Since rails/rails@d126c0d , we are now using `BigDecimal` which does
not implicitely call `to_f` on the argument, making the validator
fail with an underlying `TypeError` exception.
This patch replate the `is_decimal?` check with `Kernel.Float`.
Using `Kernel.Float` as argument for the BigDecimal call has two
advantages:
1. It calls `to_f` implicetely for us.
2. It's also smart enough to detect that `Kernel.Float("a")` isn't a
Numeric and will raise an error.
We don't need the `is_decimal?` check thanks to that.
Passing `Float::DIG` as second argument to `BigDecimal` is mandatory
because the precision can't be omitted when passing a Float.
`Float::DIG` is what is used internally by ruby when calling
`123.to_d`
https://github.com/ruby/ruby/blob/trunk/ext/bigdecimal/lib/bigdecimal/util.rb#L47
- Another small issue introduced in https://github.com/rails/rails/pull/34693
would now raise a TypeError because `Regexp#===` will just return
false if the passed argument isn't a string or symbol, whereas
`Regexp#match?` will.
