Is there a way to specify an output folder for scaffolding? In the example below I would like the generated context file placed in the "DataAccess" folder
Scaffold DbContext Product WebAPIContext -Folder DataAccess
This returns the following error:
Invoke-Scaffolder : A parameter cannot be found that matches parameter name 'Folder'.At line:1
char:49
+ Scaffold DbContext Product WebAPIContext -Folder <<<< DataAccess
+ CategoryInfo : InvalidArgument: (:) [Invoke-Scaffolder], ParameterBindingException
+ FullyQualifiedErrorId : NamedParameterNotFound,T4Scaffolding.Cmdlets.InvokeScaffolderCmdlet
Is this supported?

I am trying to run the following PowerShell script from within my .NET application:
try {
Start-Process "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -ArgumentList "--headless --disable-gpu --print-to-pdf=c:\myDir\file.pdf https://www.bing.com"
$x = "Complete"
$x | Out-File C:\myDir\error.txt
}
Catch {
$_ | Out-File C:\myDir\error.txt
}
Simply, the above will create a pdf based upon bing.com website
In my dev environment it runs fine as a PowerShell script. It also runs fine on the production server (again, as a PowerShell script).
The issue occurs when I invoke this PowerShell script from my web app on the production server. My C# code is
var command = "c:\myDir\ps.ps1";
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "powershell.exe";
psi.Arguments = command;
Process process = new Process();
process.StartInfo = psi;
process.Start();
This works fine on my dev machine. It fails on the production server. The error.txt file is written to disc which suggests it's not a permissions issue. However, the content of the error.txt file always shows "complete". It never errors.
So, it appears that the catch in the PowerShell script is never being hit. As such, no error message. There is no exception thrown in the C# code. Regardless, it isn't working.
How can I debug this?
Or, if easier, I'm happy to run the code directly instead of invoking the PowerShell script file but the following also does 'nothing'.
var command = $"\"C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe\" -ArgumentList \"--no-sandbox --headless --disable-gpu --print-to-pdf={imagePath} {fullUrl}";
I was able to reproduce your problem. It is caused by the fact that web application on your production server is running under the user that is not currently logged in. It is running under identity of assigned application pool. Chrome has known issue of not working correctly if it's launched under the user different from currently logged user. If you check that link, you will see that issue was registered in December 2012 and still is not resolved. You could easily reproduce the problem if launch Chrome under the different user ("Run as different user" in shortcut context menu when called with pressed Shift). In this case Chrome will not open any page and will just show gray screen.
The workaround is to launch Chrome with --no-sandbox switch. Google actually does not recomment this. However if you run Chrome in automated way to access trusted source, I believe it's ok.
So to fix the problem modify start-process in the script in the following way:
start-process "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -ArgumentList "--no-sandbox --headless --disable-gpu --print-to-pdf=c:\myDir\file.pdf https://www.bing.com"
UPDATE
I have underestimated the problem at first. Now after additional research and many tried approaches I can propose solution that works.
I didn't manage to fix your current approach of direct launch of powershell and chrome from Web Application. Chrome just fails to start and following errors appear in Event log:
Faulting application name: chrome.exe, version: 64.0.3282.186, time stamp: 0x5a8e38d5
Faulting module name: chrome_elf.dll, version: 64.0.3282.186, time stamp: 0x5a8e1e3d
Exception code: 0x80000003

Report Id: e70a5a36-26a4-11e8-ac26-b8ca3a94ba80
This error occurrs even if you configure application pool to use identity of some existing (ordinary) user that could launch the chrome.
May be it's possible to configure IIS or application pool to prevent these errors but I have not found the way.
My proposal is to switch from starting powershell process from controller action to scheduling a task with Windows task scheduler.
Here are the steps that should be taken to accomplish this task:
On your production server create a user under which the Chrome will be started. I'll refer to created user as 'testuser'.
Login under testuser, start chrome, open some site. Without this step, the flow was not successfully, probably because of missing chrome user account.
Grant "Log on as a batch job" right for testuser. This step is required for successfull execution of scheduled tasks under testuser. The procedure is described in this answer
Add --no-sandbox argument to the script as I described in my initial answer.
Replace the code of Process.Start() with scheduling of the task job.
The easiest way to schedule a task from .Net is via TaskScheduler NuGet. Install it to your application and add following code:
string powerShellScript = #"c:\myDir\ps.ps1";
string userName = #"YOURCOMP\testuser";
string userPassword = "TestPwd123";
using (TaskService ts = new TaskService())
{
TaskDefinition td = ts.NewTask();
td.Triggers.Add(new RegistrationTrigger
{
StartBoundary = DateTime.Now,
EndBoundary = DateTime.Now.AddMinutes(1),
});
td.Settings.DeleteExpiredTaskAfter = TimeSpan.FromSeconds(5);
td.Actions.Add(new ExecAction("powershell.exe", powerShellScript));
ts.RootFolder.RegisterTaskDefinition($#"Print Pdf - {Guid.NewGuid()}", td, createType: TaskCreation.Create, userId: userName, password: userPassword, logonType: TaskLogonType.Password);
}
In above code snippet change the name and password for testuser.
With this approach your script is successfully executed and pdf is printed successfully.
Update by OP
If the above continues to fail, then again, check the Event Viewer logs. In this case, I had an issues with a message similar to The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID {20FD4E26-8E0F-4F73-A0E0-F27B8C57BE6F} and APPID Unavailable but it was resolved by granting permissions for the CLSID. Further, try to run the task in task scheduler by itself, such as create a new task to simply launch notepad or similar to make sure that this is working with the account you want to test. In my case, I had to use the administrator account.
I think additional to what CodeFuller said having no sandbox with --no-sandbox option, you should also disable all extensions, sync and bookmarks.
The best is having a Guest session alias "browse without sign-in" with--bwsi option.
What is funny is that during testing I have found out that it is better, got better pdf printout, to disable extensions explicitly with --disable-extensions before doing --bwsi.
I have tested it and for me it works. I'm looking forward for your feedback.
Edit1 and Edit3 - removing try...catch and adding user & password and adding psuser specifics
You are probably on domain so I have adjusting the script to run as different user on domain (the user must have correct rights!)
First create your credentials file with:
Login to user e.g. psuser
Create the password file:
# Encrypt user password and save it to file
Read-Host -AsSecureString | ConvertFrom-SecureString | Out-File 'C:\<your_path>\your_secret_password.txt'
Then run the below improved script with encrypted credentials:
$username = 'psuser' # This needs to be adjusted to correct user you are using
$domain = <your_domain> # adjust to your needs
$encrypted_passwd = get-content 'C:\<your_path>\your_secret_password.txt' | ConvertTo-securestring
# Setting process invocation parameters.
$process_start_info = New-Object -TypeName System.Diagnostics.ProcessStartInfo
$process_start_info.CreateNoWindow = $true
$process_start_info.UseShellExecute = $false
$process_start_info.RedirectStandardOutput = $true
$process_start_info.RedirectStandardError = $true
$process_start_info.UserName = $username
$process_start_info.Domain = $domain
$process_start_info.Password = $encrypted_passwd
$process_start_info.Verb = 'runas'
$process_start_info.FileName = 'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe'
$process_start_info.Arguments = '--no-sandbox --disable-extensions --bwsi --headless --disable-gpu --print-to-pdf=C:\prg\PowerShell\test\chrome_file.pdf https://www.bing.com'
# Creating process object.
$process = New-Object -TypeName System.Diagnostics.Process
$process.StartInfo = $process_start_info
# Start the process
[Void]$process.Start()
$process.WaitForExit()
# synchronous output - captures everything
$output = $process.StandardOutput.ReadToEnd()
$output += $process.StandardError.ReadToEnd()
Write-Output $output

Edit2 Adding windows account impersonation with ASP.NET
Impersonate a windows account with ASP.NET:
ASP.NET user is not passed into the new threads (by default). When you want to invoke PowerShell script it is invoked in other thread with different credentials (you can overcome that with above script when you have a dedicated domain authenticated user for running the above script). By default the script is executed under build-in account NT AUTHORITY\NETWORK SERVICE.
These steps are to overcome it on ASP.NET level:
1) Enable Windows Authentication in IIS
a) Install it first (this is windows 2008 R2 screenshot):
b) enable it on your IIS:
Change it to enabled:
2) Change your site's web.config to correctly handle impersonation
Edit the web.config file in your site’s directory. In order to execute the server side code of the current user's security context (AD).
Find the xml tag: <system.web> and add two new elements to enable the windows authentication
<authentication mode="Windows" />
<identity impersonate="True" />
3) To correctly write code to invoke in-process PowerShell script
You need to adjust your ASP.NET code in a way that you will have powershell Runspace and you will invoke the script inside the Runspace in a pipeline
A quick example:
// You need to create a Runspace. Each other pipeline you create will run in the same Runspace
// Do it only once, all others will be pipelined
RunspaceConfiguration powershellConfiguration = RunspaceConfiguration.Create();
var powershellRunspace = RunspaceFactory.CreateRunspace(powershellConfiguration);
powershellRunspace.Open();
// create a pipeline the cmdlet invocation
using ( Pipeline psPipeline = powershellRunspace.CreatePipeline() ){
// Define the command to be executed in this pipeline
Command script = new Command("PowerShell_script");
// Add any parameter(s) to the command
script.Parameters.Add("Param1", "Param1Value");
// Add it to the pipeline
psPipeline.Commands.Add(script);
try {
// Invoke() the script
var results = psPipeline.Invoke();
// work with the results
} catch (CmdletInvocationException exception) {
// Any exceptions here - for the invoked process
}
}
4) Modify aspnet.config to allow impersonation to cross threads
This step allows you to run as your current, impersonated, user.
You have to modify your servers’s aspnet.config file.
Add two xml elements to the configuration and runtime:
<configuration>
<runtime>
...
<legacyImpersonationPolicy enabled="true" />
<alwaysFlowImpersonationPolicy enabled="false" />
</runtime>
</configuration>
You have to redirect the stdin and stdout so that it sends it from powershell.exe back to the parent process (your web app). I modified your code sample to do this:
var command = "c:\myDir\ps.ps1";
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = "powershell.exe";
psi.Arguments = command;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
Process process = new Process();
process.StartInfo = psi;
process.Start();
process.WaitForExit();
Console.WriteLine(process.StandardOutput);
Console.WriteLine(process.StandardError);
I have created a "services" dir in app/ where I have created some classes (services). Now it's looks like this :
-app
-services
-class1
-class2
-class3
-class4
For now, I have added app/services in config/spring.rb
%w(
.ruby-version
.rbenv-vars
tmp/restart.txt
tmp/caching-dev.txt
app/services
app/errors
).each { |path| Spring.watch(path) }
So my classes in services are loaded.
But now, I want to do this :
-app
-services
-dir1
-class1
-class2
-dir2
-class3
-class4
I got error :
uninitialized constant TransactionService::AuthorizeRequest
How autoload a dir and subdir ?
Rails tries to guess namespaces by dirnames & filenames. So, to have a TransactionService::AuthorizeRequest class name, you should have the exact following structure:
app
- services
-- transaction_service
--- authorize_request.rb
Your class sould looks like :
module TransactionService
class AuthorizeRequest
end
end
I have recreated a simple example in this tiny github repo. I am attempting to use symfony/dependency-injection to configure monolog/monolog to write logs to php://stderr. I am using a yaml file called services.yml to configure dependency injection.
This all works fine if my yml file looks like this:
parameters:
log.file: 'php://stderr'
log.level: 'DEBUG'
services:
stream_handler:
class: \Monolog\Handler\StreamHandler
arguments:
- '%log.file%'
- '%log.level%'
log:
class: \Monolog\Logger
arguments: [ 'default', ['#stream_handler'] ]
However, my goal is to read the path of the log files and the log level from environment variables, $APP_LOG and LOG_LEVEL respectively. According to The symphony documentations on external paramaters the correct way to do that in the services.yml file is like this:
parameters:
log.file: '%env(APP_LOG)%'
log.level: '%env(LOGGING_LEVEL)%'
In my sample app I verified PHP can read these environment variables with the following:
echo "Hello World!\n\n";
echo 'APP_LOG=' . (getenv('APP_LOG') ?? '__NULL__') . "\n";
echo 'LOG_LEVEL=' . (getenv('LOG_LEVEL') ?? '__NULL__') . "\n";
Which writes the following to the browser when I use my original services.yml with hard coded values.:
Hello World!
APP_LOG=php://stderr
LOG_LEVEL=debug
However, if I use the %env(VAR_NAME)% syntax in services.yml, I get the following error:
Fatal error: Uncaught UnexpectedValueException: The stream or file "env_PATH_a61e1e48db268605210ee2286597d6fb" could not be opened: failed to open stream: Permission denied in /var/www/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:107 Stack trace: #0 /var/www/vendor/monolog/monolog/src/Monolog/Handler/AbstractProcessingHandler.php(37): Monolog\Handler\StreamHandler->write(Array) #1 /var/www/vendor/monolog/monolog/src/Monolog/Logger.php(337): Monolog\Handler\AbstractProcessingHandler->handle(Array) #2 /var/www/vendor/monolog/monolog/src/Monolog/Logger.php(532): Monolog\Logger->addRecord(100, 'Initialized dep...', Array) #3 /var/www/html/index.php(17): Monolog\Logger->debug('Initialized dep...') #4 {main} thrown in /var/www/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php on line 107
What am I doing wrong?
Ok you need a few things here. First of all you need version 3.3 of Symfony, which is still in beta. 3.2 was the released version when I encountered this. Second you need to "compile" the environment variables.
Edit your composer.json with the following values and run composer update. You might need to update other dependencies. You can substitute ^3.3 with dev-master.
"symfony/config": "^3.3",
"symfony/console": "^3.3",
"symfony/dependency-injection": "^3.3",
"symfony/yaml": "^3.3",
You will likely have to do this for symfony/__WHATEVER__ if you have other symfony components.
Now in you're code after you load your yaml configuration into your dependency container you compile it.
So after you're lines here (perhaps in bin/console):
$container = new ContainerBuilder();
$loader = new YamlFileLoader($container, new FileLocator(__DIR__ . DIRECTORY_SEPARATOR . '..'));
$loader->load('services.yml');
Do this:
$container->compile(true);
Your IDE's intellisense might tell you compile takes no parameters. That's ok. That's because compile() grabs its args indirectly via func_get_arg().
public function compile(/*$resolveEnvPlaceholders = false*/)
{
if (1 <= func_num_args()) {
$resolveEnvPlaceholders = func_get_arg(0);
} else {
. . .
}
References
Github issue where this was discussed
Pull request to add compile(true)
Using this command after loading your services.yaml file should help.
$containerBuilder->compile(true);
given your files gets also validated by the checks for proper configurations which this method also does. The parameter is $resolveEnvPlaceholders which makes environmental variables accessible to the yaml services configuration.

The grails application I am developing could run against MySQL or SQL Server. I want to add a new property in application.properties file say
database.type=MySQL // or it could be SQLSERVER
How do I get this property in Datasource.groovy so that if it is MySQL I connect to MySQL server or it is SQLSERVER I connect to SQL Server?
Is this the correct way to do it? How can I do it?
EDIT: After reading and searching for options I figured the following way explained.
I have created config.properties file in /grails-app/conf/ folder.
driverClassName = com.microsoft.sqlserver.jdbc.SQLServerDriver
dataSource.url = jdbc:sqlserver://localhost:1433;databaseName=testDB
dataSource.username = sa
dataSource.password = sa
Also updated Config.groovy
grails.config.locations = ["classpath:config.properties"]
But I get the below error
Unable to load specified config location classpath:config.properties : class path resource [config.properties] cannot be opened because it does not exist
But if use
grails.config.locations = ["file:E:/workspace/SpringSource2.3.3/GRAILS_PRO/config.properties"]
The application starts up and is able to connect to the database. I don't want to use static file path. What is wrong when using classpath?
Have the same issue for both 'run-app' and 'war' mode i.e. same file does not exist error.
2nd EDIT:
After so much frustration of using classpath and not able to get it to work, I resorted to using environment property. Since server will have CATALINA_HOME defined, I used the below to build the path for external configuration file.
def CATALINA_HOME = "CATALINA_HOME"
def CONFIG_FILE_NAME = "db_config.properties"
if(!grails.config.locations || !(grails.config.locations instanceof List)) {
grails.config.locations = []
}
if(System.getenv(CATALINA_HOME)) {
def fullPath = System.getenv(CATALINA_HOME) + File.separator + "webapps" + File.separator + "${appName}" + File.separator + "WEB-INF" + File.separator + "classes" + File.separator + CONFIG_FILE_NAME
grails.config.locations << "file:" + fullPath
} else {
println "Missing configuration!"
}
The above solution is Tomcat specific. I really would like to see classpath version working!
Thank You.
Regards,
Jay Chandran.
put it in the home directory of the user which is running the instance of tomcat or there should be a .grails directory created for your app , put it under there
