I'm using DataMapper's validations, but I can't get the error messages text :(
I tried:
#error = user.errors.first
#error = user.errors.full_messages.first
#error = user.errors.full_messages.flatten
#error = user.errors[0]
But still I get an array :(
In my template I have
- if #error
%p.lead= #error
And I get ["This username is taken"]
If I have
- if #error
- #error.each do |er|
%p.lead= er
it works, but isn't there a way to send only a string to the template and it to work with the %p = #error ?
If #error is an array, which it seems to be, then that's how it will show up.
What you probably want is:
#error = user.errors.full_messages.flatten.join(', ')
Something like that will collapse it to a string. flatten returns an Array.

I want to run several jobs with Condor, my executable take as an argument b such that: b1=50+ $(($(Process)/41)), where $(())stands for the quotient of $(Process) divided by 41. b is defined in quotient.sh. Here is my submit file:
# Unix submit description file
include : PATH/quotient.sh
executable = PATH/script_test.sh
arguments = $(b) $(Process)
log = fit_it_data_$INT(b)_$(Process).log
output = outfile_fit_$INT(b)_$(Process).txt
error = errors_fit_$INT(b)_$(Process).txt
transfer_input_files = PATH
should_transfer_files = Yes
when_to_transfer_output = ON_EXIT
queue 81
However I am getting the error Submitting job(s)ERROR at Queue statement on Line 13: $INT() macro: 50+ $((0/41)) does not evaluate to an integer!. I don't understand why it complains that is does not evaluate to an integer, since b should be equal to 50 here...
Any idea how to fix that issue?
b1=50+ $(($(Process)/41))
I think you have an extra "$" in there. Try this:
b1=50+ ($(Process)/41)
I cannot explain why I get a pylint "<class 'AttributeError'>: 'For' object has no attribute 'targets'" warning when I create enum entries dynamically.
I cannot see any reason for the the warning in my code.
from aenum import IntEnum
class Commands(IntEnum):
_ignore_ = 'Commands index'
_init_ = 'value string'
BEL = 0x07, 'Bell'
Commands = vars()
for index in range(4):
Commands[f'DC{index + 1}'] = 0x11 + index, f'Device Control {index + 1}'
for command in Commands:
print(f"0x{command.value:02X} is {command.string}")
The code works fine but I do NOT expect a warning!
The code is OK the bug was within the toolchain:
https://github.com/PyCQA/pylint/issues/2719
I m new asp..
And tried to access with code
But it shows error like this.,
Error Type:
Microsoft VBScript runtime (0x800A01A8)
Object required: ''
on line 163
The error showed because of this lines,
<%
do while not getgroups2.eof
pkOrgGroups2=getgroups2("pkOrgGroups")
ogGroup2=getgroups2("ogGroup")
ogLogo2 =getgroups2("ogLogo")
%>
May i know for which reason of my code it shows like this?
Thanks in advance.
There are two sure ways to get an "Object required" error:
Trying to use Set when assigning a non-object:
>> Set x = "non-object/string"
>>
Error Number: 424
Error Description: Object required
Trying to call a method on a non-object:
>> WScript.Echo TypeName(x)
>> If x.eof Then x = "whatever"
>>
Empty
Error Number: 424
Error Description: Object required
or:
>> x = "nix"
>> WScript.Echo TypeName(x)
>> If x.eof Then x = "whatever"
>>
String
Error Number: 424
Error Description: Object required
As there is no Set in the code you posted, one has to assume that getgroups2 is not an object. Use TypeName() to check.
I have an issue compiling my pebble watchapp. I am trying to send strings to the Pebbl eJS script on the phone lihe this:
Tuplet password_tuple = TupletCString(PASSWORD_KEY, password_str);
Tuplet email_tuple = TupletCString(EMAIL_KEY, email_str);
The compiler error is: (they both error out like this, this is just one of the lines of output below)
./src/app_test.c:84:25: error: the address of 'email_str' will always evaluate as 'true' [-Werror=address]
email_str and password_str are defined at the top of the program, like this:
static char email_str[30];
static char password_str[30];
#define PASSWORD_PKEY (int32_t)21
#define EMAIL_PKEY (int32_t)20
Does anyone notice anything wrong with this?
#ismail-badawi answer is very correct.
Pebble now recommends that you use dict_write_cstring.
dict_write_cstring(&iter, SOME_STRING_KEY, string);
Well it's certainly not obvious, but it turns out it's because TupletCString is a macro, and it'll expand to an expression that contains email_str ? strlen(email_str) + 1 : 0 as a subexpression, and this is what causes the error, because email_str can't be null and so the comparison isn't doing anything.
I found this thread on the Pebble forums with an explanation. The suggested fix is to define your own macro that doesn't have a conditional, e.g.
#define MyTupletCString(_key, _cstring) \
((const Tuplet) { .type = TUPLE_CSTRING, .key = _key, .cstring = { .data = _cstring, .length = strlen(_cstring) + 1 }})
In an app I recently built for a client the following code resulted in the variable #nameText being evaluated, and then resulting in an error 'no text' (since the variable doesn't exist).
To get around this I used gsub, as per the example below. Is there a way to tell Magick not to evaluate the string at all?
require 'RMagick'
#image = Magick::Image.read( '/path/to/image.jpg' ).first
#nameText = '#SomeTwitterUser'
#text = Magick::Draw.new
#text.font_family = 'Futura'
#text.pointsize = 22
#text.font_weight = Magick::BoldWeight
# Causes error 'no text'...
# #text.annotate( #image, 0,0,200,54, #nameText )
#text.annotate( #image, 0,0,200,54, #nameText.gsub('#', '\#') )
This is the C code from RMagick that is returning the error:
// Translate & store in Draw structure
draw->info->text = InterpretImageProperties(NULL, image, StringValuePtr(text));
if (!draw->info->text)
{
rb_raise(rb_eArgError, "no text");
}
It is the call to InterpretImageProperties that is modifying the input text - but it is not Ruby, or a Ruby instance variable that it is trying to reference. The function is defined here in the Image Magick core library: http://www.imagemagick.org/api/MagickCore/property_8c_source.html#l02966
Look a bit further down, and you can see the code:
/* handle a '#' replace string from file */
if (*p == '#') {
p++;
if (*p != '-' && (IsPathAccessible(p) == MagickFalse) ) {
(void) ThrowMagickException(&image->exception,GetMagickModule(),
OptionError,"UnableToAccessPath","%s",p);
return((char *) NULL);
}
return(FileToString(p,~0,&image->exception));
}
In summary, this is a core library feature which will attempt to load text from file (named SomeTwitterUser in your case, I have confirmed this -try it!), and your work-around is probably the best you can do.
For efficiency, and minimal changes to input strings, you could rely on the selectivity of the library code and only modify the string if it starts with #:
#text.annotate( #image, 0,0,200,54, #name_string.gsub( /^#/, '\#') )
