I'm trying to use a feeder in a resource however on the subpage I get a
No attribute named 'searchCriterion' is defined
The second one is found however. How do I use a feeder in a resource?
object Search {
val feeder = csv("search.csv").random
val search = group("mygroup") {
exec(http("Home")
.get("/")
.resources(http("subpage")
.get("/subpage")
.queryParam("""f""", "${searchCriterion}")))
.feed(feeder)
.exec(http("Search")
.get("/computers")
.queryParam("""f""", "${searchCriterion}")
)
}
}
Your problem as nothing to do with resources: you're trying to use the searchCriterion attribute BEFORE actually setting it!
Move the feed call BEFORE the exec(http("Home")...) block

When I was using gtk3 I was able to access a ListBox's children this way:
let list_box = ListBox::new();
let label = Label::new(Some("Label 1"));
list_box.append(&label);
for row in list_box.children() {
list_box.remove(&row);
}
In gtk4, it seems like children() doesn't exist anymore: "no method named `children` found for struct `gtk4::ListBox`".
I checked ListBox in the gtk4 docs, but I couldn't find anything related to accessing a ListBox's children.
How to access a ListBox's children in gtk4?
There is observe_children, but like it's name suggests you should not modify the container while using it. Or more specifically you can't keep using it's iterator once you modify the underlying container.
For your usecase you can iterate and remove children using first_child/last_child like this:
while let Some(row) = list_box.last_child() {
list_box.remove(&row);
}
I want to get all the attributes from my "Actual Item Inventry" (From Stock Items Form) so i have:
PXResultset<CSAnswers> res = PXSelectJoin<CSAnswers,
InnerJoin<InventoryItem,
On<CSAnswers.refNoteID, Equal<Current<InventoryItem.noteID>>>
>
>.Select(new PXGraph());
But, this returns me 0 rows.
Where is my error?
UPDATED:
My loop is like this:
foreach (PXResult<CSAnswers> record in res)
{
CSAnswers answers = (CSAnswers)record;
string refnoteid = answers.RefNoteID.ToString();
string value = answers.Value;
}
... but i can not go inside foreach.
Sorry for the English.
You should use an initialized graph rather than just "new PXGraph()" for the select. This can be as simple as "this" or "Base" depending on where this code is located. There are times that it is ok to initialize a new graph instance, but also times that it is not ok. Not knowing the context of your code sample, let's assume that "this" and "Base" were insufficient, and you need to initialize a new graph. If you need to work within another graph instance, this is how your code would look.
InventoryItemMaint graph = PXGraph<InventoryItemMaint>.CreateInstance<InventoryItemMaint>();
PXResultset<CSAnswers> res = PXSelectJoin<CSAnswers,
InnerJoin<InventoryItem, On<CSAnswers.refNoteID, Equal<Current<InventoryItem.noteID>>>>>
.Select(graph);
foreach (PXResult<CSAnswers> record in res)
{
CSAnswers answers = (CSAnswers)record;
string refnoteid = answers.RefNoteID.ToString();
string value = answers.Value;
}
However, since you should be initializing graph within a graph or graph extension, you should be able to use:
.Select(this) // To use the current graph containing this logic
or
.Select(Base) // To use the base graph that is being extended if in a graph extension
Since you are referring to:
Current<InventoryItem.noteID>
...but are using "new PXGraph()" then there is no "InventoryItem" to be in the current data cache of the generic base object PXGraph. Hence the need to reference a fully defined graph.
Another syntax for specifying exactly what value you want to pass in is to use a parameter like this:
var myNoteIdVariable = ...
InventoryItemMaint graph = PXGraph<InventoryItemMaint>.CreateInstance<InventoryItemMaint>();
PXResultset<CSAnswers> res = PXSelectJoin<CSAnswers,
InnerJoin<InventoryItem, On<CSAnswers.refNoteID, Equal<Required<InventoryItem.noteID>>>>>
.Select(graph, myNoteIdVariable);
foreach (PXResult<CSAnswers> record in res)
{
CSAnswers answers = (CSAnswers)record;
string refnoteid = answers.RefNoteID.ToString();
string value = answers.Value;
}
Notice the "Required" and the extra value in the Select() section. A quick and easy way to check if you have a value for your parameter is to use PXTrace to write to the Trace that you can check after refreshing the screen and performing whatever action would execute your code:
PXTrace.WriteInformation(myNoteIdVariable.ToString());
...to see if there is a value in myNoteIdVariable to retrieve a result set. Place that outside of the foreach block or you will only get a value in the trace when you actually get records... which is not happening in your case.
If you want to get deep into what SQL statements are being generated and executed, look for Request Profiler in the menus and enable SQL logging while you run a test. Then come back to check the results. (Remember to disable the SQL logging when done or you can generate a lot of unnecessary data.)
I try to create an attribute trait. The use case is to mark some attributes of a class as "crudable" in the context of an objects-to-documents-mapping while other are not.
role crud {
has Bool $.crud is default(True);
}
multi trait_mod:<is>(Attribute $a, crud, $arg) {
$a.container.VAR does crud($arg);
}
class Foo {
has $.bar is rw;
# Provide an extra nested information
has $.baz is rw is crud(True);
}
By reading and adapting some example code, I managed to get something that seems to do what I want. Here is a snippet with test case.
When I instantiate a new Foo object and set the $.bar attribute (that is not crud), it looks like that:
.Foo #0
├ $.bar is rw = 123456789
└ $.baz is rw = .Scalar+{crud} #1
└ $.crud +{crud} = True
What I understand from this is that the $.baz attribute got what I call a meta-attribute that is independent from its potential value.
It looks good to me (if I understood correctly what I did here and that my traits use is not a dirty hack). It is possible to reach $foo.baz.crud that is True. Though, I don't understand very well what .Scalar+{crud} means, and if I can set something there and how.
When I try to set the $.baz instance attribute, this error is returned:
Cannot modify an immutable Scalar+{crud} (Scalar+{crud}.new(crud => Bool::True))
in block <unit> at t/08-attribute-trait.t line 30
Note: This is the closest thing to a working solution I managed to get. I don't need different crud settings for different instances of instantiated Foo classes.
I never want to change the value of the boolean, in fact, once the object instantiated, just providing it to attributes with is crud. I am not even interested to pass a True or False value as an argument: if it would be possible to just set the boolean trait attribute to True by default, it would be enough. I didn't manage to do this though, like:
multi trait_mod:<is>(Attribute $a, :$crud!) {
# Something like this
$a.container.VAR does set-crud;
}
class Foo {
has $.bar is rw;
has $.baz is rw is crud;
}
Am I trying to do something impossible? How could I adapt this code to achieve this use case?
There are several things going on here. First of all, the signature of the trait_mod looks to be wrong. Secondly, there appears to be a bad interaction when the name of a trait is the same as an existing role. I believe this should be an NYI exception, but apparently it either goes wrong in parsing, or it goes wrong in trying to produce the error message.
Anyways, I think this is what you want:
role CRUD {}; # since CRUD is used as an acronym, I chose to use uppercase here
multi trait_mod:<is>(Attribute:D $a, :$crud!) { # note required named attribute!
$a.^mixin: CRUD if $crud; # mixin the CRUD role if a True value was given
}
class A {
has $.a is crud(False); # too bad "is !crud" is invalid syntax
has $.b is crud;
}
say "$_.name(): { $_ ~~ CRUD }" for A.^attributes; # $!a: False, $!b: True
Hope this helps.
My requirement is to do some repetitive file configuration stuff using a loop, Something like following,
$no_of_managers = 2
$array = ['One','two','Three']
define loop() {
notice("Configuring The Manager Nodes!!")
if ($name == $no_of_managers+1) {
notice("Loop Iteration Finished!!!")
}
else
{
notice("Iteration Number : $name \n")
# Doing All Stuff Here
resource {$array:}
$next = $name + 1
loop { $next: }
}
}
loop { "1":}
define resource () {
# Doing my other Stuff
notice ("The Parsed value Name : ${name}\n")
}
Now when The second iteration is running the following error occurs,
Error: Duplicate declaration: Resource[One] is already declared in file
How can I overcome this, What I'm doing is a cluster setup. Is there a workaround to do this, I'm a newbie for puppet so Your kind guidance highly appreciated.
The Use Case :
I'm trying to setup a cluster which have multiple Manager/Worker nodes, So using this script the user has the privilege to select how many manager nodes he needs. So the first loop is for that to copy necessary files and create required number of nodes.
The second loop is there to push all .erb templates. Because each Node has slightly different configs the .erb files have there own logic inside them.
So after each Iteration I want to push the .erb templates to the respective node.
In Puppet 3.x, you cannot build a loop in the fashion you are trying.
resource { $array: }
is a loop over the contents of $array if you will.
It is not really clear what you are trying to solve. If you can make your question a bit more concrete, we may be able to suggest an actual implementation.
Update
If you really want to go down this road, you need to generate unique names for your derived resources.
$local_names = regsubst($array, '$', "-$name")
resource { $local_names: }
In your defined type, you will have to retrieve the original meaning by removing the suffix.
define resource() {
$orig_name = regsubst($name, '-[0-9]+$', '')
# use $orig_name where you used $name before
}
Note that even exported resources must have unique names. So the transformation may have to happen on in the manifest of the receiving node.
symfony getLayout does not seem to work when layout is set via view.yml. Is there anyway to get this within the controller's action class method
I recently needed this. You can do it but you just need to return the entire view.yml contents as an array:
$view_array = sfViewConfigHandler::getConfiguration(array(sfConfig::get('sf_app_config_dir').'/view.yml'));
Just adjust the relative path from sf_app_config_dir (or use another marker) to get what you need.
It's not a trivial task. The view.yml, is not in the "scope" of the action.
Maybe, you can use setLayout in your action rather then in view.yml.
if you can't, for some reasons... you can try this method to reach datas in view.yml:
Is it possible to get a value from view.yml in an action
Execute the following code in the action. It works for both cases, layout set in the action or in the view.yml.
$controller = $this->getContext()->getController();
$view = $controller->getView($this->getModuleName(), $this->getActionName(), 'Success'); // viewName == 'Success' (default)
$layout_name = $view->getDecoratorTemplate(); // e.g expected: layout.php
Let us know if it works for you.
