I can't figure out why in the following line of code
res = https.get(url, nil)
The application stops and give me the following exception:
undefined method `keys' for nil:NilClass
The strange things is that this error happens only in my development enviroment, when I put the application online (heroku), everyhthing work like a charm.
That above line of code, use this inclusion:
require 'net/https'
Is anybody able to explain me why ?
Tnx
If you don't want to pass any headers just use:
res = https.get(url, {})
in the documentation for Net::HTTP this method definition is
def get(path, initheader = {}, dest = nil, &block) # :yield: +body_segment+
res = nil
if HAVE_ZLIB
unless initheader.keys.any?{|k| k.downcase == "accept-encoding"}
initheader["accept-encoding"] = "gzip;q=1.0,deflate;q=0.6,identity;q=0.3"
#compression = true
....
in your code initheader is nil so error happens on line four initheader.keys It may work fine on heroku because there is if HAVE_ZLIB which can be faulse so code is skipped.

I am trying to make a errorhandling for my Discord.py, how do I know what command was used for the error to pop up?
#bot.event
async def on_command_error(ctx, error):
print("error: ",error)
if search("not found", str(error)):
c_f = random.choice([f"`{command used}` was not found, silly.", "Ehm.. Since when do we have `{command used}`?", "I don't know what `{command used}` is?"])
embed=discord.Embed(title=c_f, description=f"Please use existing commands. {ctx.author.mention}", color=error_color)
embed.timestamp = datetime.utcnow()
embed.set_footer(text=bot_name, icon_url=icon_uri)
await ctx.send(embed=embed)
elif search("cooldown", str(error)):
c_d = random.choice(["Did you drink energy drinks!?", "Why are you stressing, buddy.", "Duhh, wait, you're on cooldown!"])
second_remain = round(error.retry_after, 1)
embed=discord.Embed(title=c_d, description=f"Try again after {second_remain}s. {ctx.author.mention}", color=error_color)
embed.timestamp = datetime.utcnow()
embed.set_footer(text=bot_name, icon_url=icon_uri)
await ctx.send(embed=embed)
else:
raise error
Any attribute I can use?
You can use ctx.command
#bot.event
async def on_command_error(ctx, exception):
error = getattr(exception, "original", exception)
if hasattr(ctx.command, "on_error"): # If a command has it's own handler
return
elif isinstance(error, CommandNotFound):
return
if isinstance(error, discord.CommandInvokeError):
print(ctx.command)
Your solution is to add them to the command specifically, this also means it can help diagnose an issue with a command more exact.
You can also add any error events to the specific listener, just like how you done it for all commands, instead add them individually.
#bot.command()
async def command_name(ctx):
# ...
#command_name.error
async def command_name_error(ctx, error):
if isinstance(error, commands.CommandInvokeError):
await ctx.send("An error from this command" + error)
With #command_name.error put your command name before the .error, then this makes an error listener for that command, if it produces an error.
I'm trying to use Plug.Test to test error handling implemented with Plug.ErrorHandler -- with assert conn.status == 406 and alike.
I have the defp handle_errors (containing a single send_resp statement) and it seems to be called, however, my tests fail with the same exception still (as if handle_errors has no effect).
A reference to a sample advanced Plug (not Phoenix) app will also be appreciated.
Try something like this (not tested):
defmodule NotAcceptableError do
defexception plug_status: 406, message: "not_acceptable"
end
defmodule Router do
use Plug.Router
use Plug.ErrorHandler
plug :match
plug :dispatch
get "/hello" do
raise NotAcceptableError
send_resp(conn, 200, "world")
end
def handle_errors(conn, %{kind: _kind, reason: reason, stack: _stack}) do
send_resp(conn, conn.status, reason.message)
end
end
test "error" do
conn = conn(:get, "/hello")
assert_raise Plug.Conn.WrapperError, "** (NotAcceptableError not_acceptable)", fn ->
Router.call(conn, [])
end
assert_received {:plug_conn, :sent}
assert {406, _headers, "not_acceptable"} = sent_resp(conn)
end
Use assert_error_sent/2 to assert that you raised an error and it was wrapped and sent with a particular status. Match against its {status, headers, body} return value to assert the rest of the HTTP response met your expectations.
response = assert_error_sent 404, fn ->
get(build_conn(), "/users/not-found")
end
assert {404, [_h | _t], "Page not found"} = response
i work on grails project
def result = "customer"
//(this value is according to returned method parameter,
//it may be customer, company,... & so on)
def messages = "${message(code: 'default.result.${result}', default:'${result}')}"
i need to send a variable inside message code as i mention above
problem: this code appears as
default.result.${result}
that there is no code in message.properties refer to these code
there is default.result.customer ....$ so on
Question: how can i send variable inside message Code?
Try omitting the double quotes (GString) and it should work like the following:
def xxx = "bar"
def m = message(code: "foo.${xxx}", args: ['hello world'])
Results in following message-code
foo.bar
Try:
def messages = message(code: 'default.result.' + result, default: result)
If you want to pass in some values, e.g. a string, you can define your message like this:
default.result.success = Action {0} was successfull.
And resolve your code like this:
def m = message(code: 'default.result.' + result, args: ['delete User'])
This used to work but after some modifications by the other programmers it just fails to work. I have this code on my Bootstrap:
protected function _initDatabase ()
{
$resource = $this->getPluginResource('multidb');
$resource->init();
Zend_Registry::set('gtap', $resource->getDb('gtap'));
Zend_Registry::set('phpbb', $resource->getDb('phpbb'));
}
Upon loading, this error shows up:
Fatal error: Call to a member function init() on a non-object in
/var/www/gamebowl3/application/Bootstrap.php on line 105
My php.ini has this entry on tis include_path:
.:/usr/share/php:/etc/apache2/libraries
and the i can see that multidb.php is located in:
/etc/apache2/librarties/Zend/Application/Resource
Can somebody tell me what causes the error? Thanks!
I just found out that the problem is in application.ini. Added a newly-introduced setting to the usual set of configs. Here it is:
;Gtap Database
resources.multidb.gtap.adapter = "PDO_MYSQL"
resources.multidb.gtap.host = "localhost"
resources.multidb.gtap.username = "root"
resources.multidb.gtap.password = "letmein1"
resources.multidb.gtap.dbname = "gtap"
resources.multidb.gtap.isDefaultTableAdapter = true
resources.multidb.gtap.default = true
;Forum Database
resources.multidb.phpbb.adapter = "PDO_MYSQL"
resources.multidb.phpbb.host = "localhost"
resources.multidb.phpbb.username = "root"
resources.multidb.phpbb.password = "letmein1"
resources.multidb.phpbb.dbname = "phpbb"
resources.multidb.phpbb.isDefaultTableAdapter = false
Also, make sure you have the latest Zend Framework Library and add it to PHP's include path. That should fix everything up.
I'm getting the following error:
NoMethodError in Users#new
Showing .../app/views/users/form/_new.haml where line #7 raised:
undefined method `on' for #<ActiveModel::Errors:0x007fb599ec6610>
The code in line 7 is:
7: = errors_for user, :first_name
And the application_helper.rb:
def errors_for(model, field)
error = case errors = model.errors.on(field)
...
end
'on' is a default method in ActiveRecord. Why doesn't this work?
If you're using Rails 3, then the problem is that there's no "on" method for the Errors class anymore. I think you're supposed to use "get" now. So:
error = case errors = model.errors.get(field)
Or...
error = case errors = model.errors[field]
I checked my user and u.errors is an ActiveRecord::Errors, while I see you have an ActiveModel::Error, I would work on that.
Then I don't understand case errors = statement in your helper, I'm curious to know how you implemented that part...
