I have a checkbox in our application that can have 1 of 3 options:
Checked (True)
Not Checked (False)
Use Customer (Account) settings (from a checkbox above that would then grey out the checkbox.
If the "Use Customer..." box is checked, the box with the arrow pointing to it greys out & the value is deleted from the database.
If it's checked, "True"
If it's not checked but "Use Customer..." is not checked, "False"
If "Use Customer..." is checked, there is no record.
My issues is pulling the SQL for it. I can pull the TRUE/FALSE value with no issues. I'm stuck trying to get the t-sql to return SOMETHING if the record is blank.
Currently I have this that works fine:
CASE when cb.tvalue.value('declare namespace y="http://schemas.xyzpdg.com/framework/resources";y:Item[1]', 'varchar(25)') = 'True' THEN 'Checked'
when cb.tvalue.value('declare namespace y="http://schemas.xyzpdg.com/framework/resources";y:Item[1]', 'varchar(25)') = 'False' THEN 'Unchecked'
END AS [CheckboxValue]--
I've tried using:
When COUNT(cb.tvalue.value('declare namespace y="http://schemas.xyzpdg.com/framework/resources";y:Item[1]', 'varchar(25)')) = 0 then 'Use Customer...'
But when I use that I of course get a the infamous ..."invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause."
error. And I can't use XML as a GROUP BY.
Any ideas? Thank you.
If I understand correctly, it seems that either you may use exist xml type method or simply else branch of the case statement, see sample:
declare #xml xml;
--set #xml = '<Test><Item>False</Item></Test>';
--set #xml = '<Test><Item>True</Item></Test>';
set #xml = '<Test />';
select
case
when #xml.value('(/Test/Item)[1]', 'varchar(25)') = 'True' then 'Checked'
when #xml.value('(/Test/Item)[1]', 'varchar(25)') = 'False' then 'Unchecked'
when #xml.exist('(/Test/Item)[1]') = 0 then 'Use Customer...'
end [CheckboxValue];
select
case
when #xml.value('(/Test/Item)[1]', 'varchar(25)') = 'True' then 'Checked'
when #xml.value('(/Test/Item)[1]', 'varchar(25)') = 'False' then 'Unchecked'
else 'Use Customer...'
end [CheckboxValue];

I have a Form posting variables containing spaces in their names
e.g.
I perform my ajax request and i can see in chrome inspector that name is correctly passed "with blank space)
In my api.php:
Route::post('/user', 'UserController#get');
UserController
function get(Request $request)
{
dd($request->input('Name Surname')); //display null
dd($request->all()); //I notice the key's changed to Name_Surname
}
Taken that I can't change the names because they have to contain spaces (bad practice? ok but it has to be like that):
how can I avoid spaces to be replaced?
(maybe without to have to manipulate the request->all() returned array keys by hand....)
Short answer I don't believe there to be such a way.
You can map the response with a bit of string replace though:
$data = $request->all()->mapWithKeys(function($item, $key) {
return [str_replace("_", " ", $key) => $item];
});
If it's something you want to apply across the board, you could possible rig up some middleware to apply it to all requests.
If previous answer not work for you, try this:
$data = collect($request->all())->mapWithKeys(function($item, $key) {
return [str_replace("_", " ", $key) => $item];
})->toArray();
You may also normalize the Input Name if it is known...
$field_name = 'FIELD NAME WITH SPACES';
$value = request( str_replace( ' ', '_', $field_name ) );
I need a little help with Drools eval and variable assigning.
rule "check that no previously submitted requests exist"
when
$user : UserFormField( name == 'employeeId', value != null )
$repository : Repository( )
$activeRequests : List( ) from $repository.findActiveRequestsByEmployee( $user.getValue() ) # call to repository
eval( $activeRequests.size() > 0 )
then
System.err.println(' You have active requests: ' + ((Request)$activeRequests.get(0)).getTitle);
insert(Boolean.TRUE);
end
In this rule I try to access repository and get active requests for current user. Rule compiles and executes without any exceptions or warnings. In debug mode it can be seen that repository returns non empty list and I expect to see console message 'You have active requests' but this doesn't happen. I think the problem is in this line
$activeRequests : List( ) from $repository.findActiveRequestsByEmployee( $user.getValue() )
because this rule works fine
rule "check that no previously submitted requests exist"
when
$user : UserFormField( name == 'employeeId', value != null )
$repository : Repository( )
eval( $repository.findActiveRequestsByEmployee($user.getValue()).size() > 0 )
then
System.err.println(' You have active requests !' );
insert(Boolean.TRUE);
end
So could someone point me how to solve this problem?
Thanks!
I was helped to find a solution. I should use from collect expression instead simple from to bundle facts into collection :
$activeRequests : ArrayList() from collect ( Request() from $repository.findActiveRequestsByEmployee( $user.getValue() ) )
You have to distinguish (i.e., read the fine print in the
documentation) between "from" and "from collect". If you want the rule
to fire individually for each collection element produced by the
expression after "from", then use "from". If, however, you want to
have it all bundled into a collection you must used "from collect".
$activeRequests : ArrayList() from collect ( Request() from
$repository.findActiveRequestsByEmployee( $user.getValue() ) )
Note that the separate eval isn't necessary. You can put this
constraint into the ArrayList pattern:
ArrayList( size > 0 )
In my Application_Model_DbTable_User, I have the following function:
public function deleteUser($username)
{
$this->delete('username = ' . (string) $username);
}
This function is being called from my AdminController, with this three lines of code.
$uname = $this->getRequest()->getParam('username');
$user = new Application_Model_DbTable_User();
$user->deleteUser($uname);
This error however, turns up.
Column not found: 1054 Unknown column 'test' in 'where clause'
With test being the user I am trying to delete.
This code is adapted from a previous code which deletes based on id, a INT field, which works perfectly fine. What am I doing wrong? I would be happy to give more detailed codes if needed. Thanks.
Your query isn't quoted:
$this->delete('username = ' . (string) $username);
This equates to:
WHERE username = test
If you use the where() method, it will do this for you:
$table->where('username = ?', $username);
Or (like the example in the docs):
$where = $table->getAdapter()->quoteInto('bug_id = ?', 1235);
$table->delete($where);
I'm trying to submit a form by post method using WWW::Mechanize perl module.
use WWW::Mechanize;
my $mech = WWW::Mechanize->new();
...
$mech->get($url);
...
my $response = $mech->submit_form(
form_name => $name,
fields => {
$field_name => $field_value
},
button => 'Button'
);
$field_name is generally speaking a text field (though the type is not specified explicitly in the form), which has a preset value.
$field_name => $field_value in $mech->submit_form on whatever reason does not replace the value, instead $field_value is added into the form after the original value:
{submitted_field_value} = {original_value},{provided_value}
How to replace {original_value} with {provided_value} in the form to be submitted ?
What happens if you add this single line to your code before calling $mech->submit_form():
$mech->field( $name, [$field_value], 1 );
This makes sure that the first value is added, or overwritten if it already exists.
1 is the number parameter (or position index)
See the documentation of WWW::Mechanize:
$mech->field( $name, \#values, $number )
Given the name of a field, set its value to the value specified. [...]
The optional $number parameter is used to distinguish between two
fields with the same name. The fields are numbered from 1.
It's important to remember WWW::Mechanize is better thought of as a 'headless browser' as opposed to say LWP or curl, which only handle all the fiddly bits of http requests for you. Mech keeps its state as you do things.
You'll need to get the form by using $mech->forms or something similar (its best to decide from the documentation. I mean there so many ways to do it.), and then set the input field you want to change, using the field methods.
I guess the basic way to do this comes out as so:
$mech->form_name($name);
$mech->field($field_name, $field_value);
my $response = $mech->click('Button');
Should work. I believe it will also work if you get the field and directly use that (ie my $field = $mech->form_name($name); then use $field methods instead of $mech.
I managed to make it working at my will. Thanks Timbus and knb for your suggestions. Though my case may not be completely general (I know the preset value) but I'd share what I've found (by trails & errors).
my $mech = WWW::Mechanize->new();
$mech->get($url);
$mech->form_name( $name );
my $fields = $mech->form_name($name);
foreach my $k ( #{$fields->{inputs}}){
if ($k->{value} eq $default_value){
$k->{value}=$field_value;
}
}
my $response = $mech->click('Button_name');
I've been banging my head over this issue for about 5 hours now, I'm really frustrated and need some assistance.
I'm writing a Perl script that pulls jobs out of a MySQL table and then preforms various database admin tasks. The current task is "creating databases". The script successfully creates the database(s), but when I got to generating the config file for PHP developers it blows up.
I believe it is an issue with referencing and dereferencing variables, but I'm not quite sure what exactly is happening. I think after this function call, something happens to
$$result{'databaseName'}. This is how I get result: $result = $select->fetchrow_hashref()
Here is my function call, and the function implementation:
Function call (line 127):
generateConfig($$result{'databaseName'}, $newPassword, "php");
Function implementation:
sub generateConfig {
my($inName) = $_[0];
my($inPass) = $_[1];
my($inExt) = $_[2];
my($goodData) = 1;
my($select) = $dbh->prepare("SELECT id FROM $databasesTableName WHERE name = '$inName'");
my($path) = $documentRoot.$inName."_config.".$inExt;
$select->execute();
if ($select->rows < 1 ) {
$goodData = 0;
}
while ( $result = $select->fetchrow_hashref() )
{
my($insert) = $dbh->do("INSERT INTO $configTableName(databaseId, username, password, path)".
"VALUES('$$result{'id'}', '$inName', '$inPass', '$path')");
}
return 1;
}
Errors:
Use of uninitialized value in concatenation (.) or string at ./dbcreator.pl line 142.
Use of uninitialized value in concatenation (.) or string at ./dbcreator.pl line 154.
Line 142:
$update = $dbh->do("UPDATE ${tablename}
SET ${jobStatus}='${newStatus}'
WHERE id = '$$result{'id'}'");
Line 154:
print "Successfully created $$result{'databaseName'}\n";
The reason I think the problem comes from the function call is because if I comment out the function call, everything works great!
If anyone could help me understand what's going on, that would be great.
Thanks,
p.s. If you notice a security issue with the whole storing passwords as plain text in a database, that's going to be addressed after this is working correctly. =P

You do not want to store a reference to the $result returned from fetchrow_hashref, as each subsequent call will overwrite that reference.
That's ok, you're not using the reference when you are calling generate_config, as you are passing data in by value.
Are you using the same $result variable in generate_config and in the calling function? You should be using your own 'my $result' in generate_config.
while ( my $result = $select->fetchrow_hashref() )
# ^^ #add my
That's all that can be said with the current snippets of code you've included.
Some cleanup:
When calling generate_config you are passing by value, not by reference. This is fine.
you are getting an undef warning, this means you are running with 'use strict;'. Good!
create lexical $result within the function, via my.
While $$hashr{key} is valid code, $hashr->{key} is preferred.
you're using dbh->prepare, might as well use placeholders.
sub generateConfig {
my($inName, inPass, $inExt) = #_;
my $goodData = 1;
my $select = $dbh->prepare("SELECT id FROM $databasesTableName WHERE name = ?");
my $insert = $dbh->prepare("
INSERT INTO $configTableName(
databaseID
,username
,password
,path)
VALUES( ?, ?, ?, ?)" );
my $path = $documentRoot . $inName . "_config." . $inExt;
$select->execute( $inName );
if ($select->rows < 1 ) {
$goodData = 0;
}
while ( my $result = $select->fetchrow_hashref() )
{
insert->execute( $result->{id}, $inName, $inPass, $path );
}
return 1;
}
EDIT: after reading your comment
I think that both errors have to do with your using $$result. If $result is the return value of fetchrow_hashref, like in:
$result = $select->fetchrow_hashref()
then the correct way to refer to its values should be:
print "Successfully created " . $result{'databaseName'} . "\n";
and:
$update = $dbh->do("UPDATE ${tablename}
SET ${jobStatus}='${newStatus}'
WHERE id = '$result{'id'}'");
OLD ANSWER:
In function generateConfig, you can pass a reference in using this syntax:
generateConfig(\$result{'databaseName'},$newPassword, "php");
($$ is used to dereference a reference to a string; \ gives you a reference to the object it is applied to).
Then, in the print statement itself, I would try:
print "Successfully created $result->{'databaseName'}->{columnName}\n";
indeed, fetchrow_hashref returns a hash (not a string).
This should fix one problem.
Furthermore, you are using the variable named $dbh but you don't show where it is set. Is it a global variable so that you can use it in generateConfig? Has it been initialized when generateConfig is executed?
This was driving me crazy when I was running hetchrow_hashref from Oracle result set.
Turened out the column names are always returned in upper case.
So once I started referencing the colum in upper case, problem went away:
insert->execute( $result->{ID}, $inName, $inPass, $path );
