XPath problem - Retrieving user by name (Mendix) - database

I have Tasks entity, associated with Administration.Account entity (I use it to display a list of tasks with assigned users).
Tasks entity has a string parameter “Requester”, where I store names of users.
I created a microflow, which should retrieve an account of the user from the database, comparing his name with the name in the “Requester” parameter.
[Name = $Tasks.Requester]
The problem is, that I’m getting XPath error, and when I’m typing $Tasks. all available parameters belong to the Account entity, instead of the Tasks entity.

You must use slash (/) when constructing your XPath. So this should work in your case:
[Name = $Tasks/Requester]

Query users with a filter and expand results in unsupported query

I am trying to fetch a list of users from the Microsoft Graph API.
A lot of users don't have an email address, those users are systems users that I don't need.
So my query looks like /users?$filter=mail ne null
For another overview I need to show the manager of each user so I tried to add &$expand=manager. But doing so will result in an Unsupported Query.
When I remove the filter parameter it does work.
How can I only fetch relevant users and their managers in a single query?
Optionally I'd like to only receive the ID from managers, as an optimization. I only need the ID because I already fetched all users and their data. /users?$expand=manager($select=id) is what I was trying but I get the error Invalid $select properties.
If you want to use $select inside $expand to select the individual manager's properties, the $levels parameter is required, such as expand=manager($levels=max;$select=id). For more details, please refer to here
For example
https://graph.microsoft.com/v1.0/users?$expand=manager($levels=max;$select=id)
Update
If we want to use Not equals (ne) operators on the $filter query parameter, we must set the ConsistencyLevel header set to eventual and, with the exception of $search, use the $count query parameter (either as a URL segment or $count=true query string). For more details, please refer to here
For example
https://graph.microsoft.com/v1.0/users?$filter=mail ne null&&$expand=manager($levels=1;$select=id)&$count=true

How to find a MoveTo destination filled by database?

I could need some help with a Anylogic Model.
Model (short): Manufacturing scenario with orders move in a individual route. The workplaces (WP) are dynamical created by simulation start. Their names, quantity and other parameters are stored in a database (excel Import). Also the orders are created according to an import. The Agent population "order" has a collection routing which contains the Workplaces it has to stop in the specific order.
Target: I want a moveTo block in main which finds the next destination of the agent order.
Problem and solution paths:
I set the destination Type to agent and in the Agent field I typed a function agent.getDestination(). This function is in order which returns the next entry of the collection WP destinationName = routing.get(i). With this I get a Datatype error (while run not compiling). I quess it's because the database does not save the entrys as WP Type but only String.
Is there a possiblity to create a collection with agents from an Excel?
After this I tried to use the same getDestination as String an so find via findFirst the WP matching the returned name and return it as WP. WP targetWP = findFirst(wps, w->w.name == destinationName);
Of corse wps (the population of Workplaces) couldn't be found.
How can I search the population?
Maybe with an Agentlink?
I think it is not that difficult but can't find an answer or a solution. As you can tell I'm a beginner... Hope the description is good an someone can help me or give me a hint :)
Thanks
Is there a possiblity to create a collection with agents from an Excel?
Not directly using the collection's properties and, as you've seen, you can't have database (DB) column types which are agent types.1
But this is relatively simple to do directly via Java code (and you can use the Insert Database Query wizard to construct the skeleton code for you).
After this I tried to use the same getDestination as String an so find via findFirst the WP matching the returned name and return it as WP
Yes, this is one approach. If your order details are in Excel/the database, they are presumably referring to workplaces via some String ID (which will be a parameter of the workplace agents you've created from a separate Excel worksheet/database table). You need to use the Java equals method to compare strings though, not == (which is for comparing numbers or whether two objects are the same object).
I want a moveTo block in main which finds the next destination of the agent order
So the general overall solution is
Create a population of Workplace agents (let's say called workplaces in Main) from the DB, each with a String parameter id or similar mapped from a DB column.
Create a population of Order agents (let's say called orders in Main) from the DB and then, in their on-startup action, set up their collection of workplace IDs (type ArrayList, element class String; let's say called workplaceIDsList) using data from another DB table.
Order probably also needs a working variable storing the next index in the list that it needs to go to (so let's say an int variable nextWorkplaceIndex which starts at 0).
Write a function in Main called getWorkplaceByID that has a single String argument id and returns a Workplace. This gets the workplace from the population that matches the ID; a one-line way similar to yours is findFirst(workplaces, w -> w.id.equals(id)).
The MoveTo block (which I presume is in Main) needs to move the Order to an agent defined by getWorkplaceByID(agent.workplaceIDsList.get(nextWorkplaceIndex++)). (The ++ bit increments the index after evaluating the expression so it is ready for the next workplace to go to.)
For populating the collection, you'd have two tables, something like the below (assuming using strings as IDs for workplaces and orders):
orders table: columns for parameters of your orders (including some String id column) other than the workplace-list. (Create one Order agent per row.)
order_workplaces table: columns order_id, sequence_num and workplace_id (so with multiple rows specifying the sequence of workplace IDs for an order ID).
In the On startup action of Order, set up the skeleton query code via the Insert Database Query wizard as below (where we want to loop through all rows for this order's ID and do something --- we'll change the skeleton code to add entries to the collection instead of just printing stuff via traceln like the skeleton code does).
Then we edit the skeleton code to look like the below. (Note we add an orderBy clause to the initial query so we ensure we get the rows in ascending sequence number order.)
List<Tuple> rows = selectFrom(order_workplaces)
.where(order_workplaces.order_id.eq(id))
.orderBy(order_workplaces.sequence_num.asc())
.list();
for (Tuple row : rows) {
workplaceIDsList.add(row.get(order_workplaces.workplace_id));
}
1 The AnyLogic database is a normal relational database --- HSQLDB in fact --- and databases only understand their own specific data types like VARCHAR, with AnyLogic and the libraries it uses translating these to Java types like String. In the user interface, AnyLogic makes it look like you set the column types as int, String, etc. but these are really the Java types that the columns' contents will ultimately be translated into.
AnyLogic does support columns which have option list types (and the special Code type column for columns containing executable Java code) but these are special cases using special logic under the covers to translate the column data (which is ultimately still a string of characters) into the appropriate option list instance or (for Code columns) into compiled-on-the-fly-and-then-executed Java).
Welcome to Stack Overflow :) To create a Population via Excel Import you have to create a method and call Code like this. You also need an empty Population.
int n = excelFile.getLastRowNum(YOUR_SHEET_NAME);
for(int i = FIRST_ROW; i <= n; i++){
String name = excelFile.getCellStringValue(YOUR_SHEET_NAME, i, 1);
double SEC_PARAMETER_TO_READ= excelFile.getCellNumericValue(YOUR_SHEET_NAME, i, 2);
WP workplace = add_wps(name, SEC_PARAMETER_TO_READ);
}
Now if you want to get a workplace by name, you have to create a method similar to your try.
Functionbody:
WP workplaceToFind = wps.findFirst(w -> w.name.equals(destinationName));
if(workplaceToFind != null){
//do what ever you want
}

How to send an Email notification by day end using Rules with all the nodes published that day?

I am trying to achieve email notification . The condition is , it should go by end of the day with the current day published content list.
For the same I have tried couple of things using Rules, but stuck in between.
Any help?
I tried using rules, and I created a rule like so:
Events:
After updating existing content of type(content type name)
Cron maintenance tasks are performed
Condition: Data to compare: [node:field-img-status], Data value: Approve
When I am trying to add second condition to check if the node is published within 24hrs, I am unable to achieve it. When I add strtotime("-1 day"), I get an error like:
Wrong date format. Specify the date in the format 2017-05-10 08:17:18.
I tried date('Y-m-d h:i:s',strtotime("-1 day")) but I did not succeed.
Now I am trying one more method to achieve it using Views Rules which is suggested in this answer to the question about 'How to create a Drupal rule to check (on cron) a date field and if passed set field "status" to "ended"?'.
Below is a blueprint of how I'd get this to work ...
Step 1: Create a single eMail for each node that was published
Create a view (using Views) of all the nodes that were published the last 24 hours. Make sure to include a column in that view for the various data you want to be included about each node in your eMail later on.
Use Rules to create a rule with a Rules Action that consists of a "Rules Loop", in which its "list items" are actually the list of nodes that you want to be included in your eMail later on. To create this Rules Loop, use the Views Rules combined with a Views display type of "Views Rules", for the view that you created. Refer to my answer to "How to pass arguments to a view from Rules?" for way more details on how to use the Views Rules module.
For each list item in the Rules Loop of the previous step, you have access to all data for each column in the View you created. By using these data you could add an additional Rules Action (within the same Rules Loop) to send an appropriate eMail about the node being processed.
Step 2: Group all eMails in a single eMail
Obviously, the previous step creates a single eMail for each node that was published in the last 24 hours. If you only have a few nodes that may not be a real issue to worry about. But if you have dozens (or more?) of such nodes then you might want to consider consolidating all such eMails in a single eMail, which contains (in its eMail body) the complete list of nodes.
A possible solution to implement such consolidation, is similar to what is shown in the Rules example included in my answer to "How to concatenate all token values of a list in a single field within a Rules loop?". In your case, you could make it work like so:
Add some new Rules variable that will be used later on as part of the eMail body, before the start of your loop. Say you name the variable nodes_list_var_for_email_body.
Within your loop, for each iteration, prepend or append the value for each "list item" to that variable nodes_list_var_for_email_body.
Move the Rules Action to send an eMail outside your loop, and after the loop completed. And finetune the details (configuration) of your (new) "send an eMail" Rules Action. When doing so, you'll be able to select the token for nodes_list_var_for_email_body to include anywhere in your eMail body.
Step 3: Schedule the daily execution of your rule
Use the Rules Once per Day to schedule the daily execution of your rule. Refer to my answer to "How to limit the execution of a rule for sending an email to only run once in a day?" for way more details about this module.
Voilà, that's it ...
This is how I would achieve this:
Make some view which would list all nodes created today.
Make some end-point (from my module, check out: https://api.drupal.org/api/drupal/modules%21system%21system.api.php/function/hook_menu/7.x)
It would call this view, and grab that node list (i.e. with views_get_view_result : https://api.drupal.org/api/views/views.module/function/views_get_view_result/7.x-3.x ), loop through the list, compose the email and send it.
Then I would set cron job to call that end-point at end of every day.

Account name must be unique

What I am looking to do is Make it the "Account" name field require a unique name.
Basically If one of my reps tries to create an account, and that account all ready exists it tells them no that account all ready exists.
Salesforce tells me this funicality is not build into sales force. Any help or dirrection would we wonderfull.
Make a new text field, call it Name__c. Mark it as unique, length... probably 80, same as Name field length.
Create new Workflow rule with condition ISNEW() || ISCHANGED(Name) || ISBLANK(Name__c) and the action should be a field update that simply has Name in the formula that determines new value.
Remember to activate the workflow and to fill in the newly created field because it will be blank for all your existing accounts!
Your call if you want to show the field on page layouts (it's quite "technical" so could be hidden). If you do - it's a good idea to make it readonly!
You can use this validation:
AND(CONTAINS(VLOOKUP( $ObjectType.Account.Fields.Name , $ObjectType.Account.Fields.Name, Name), Name), OR(ISNEW(), ISCHANGED(Name)) )
Salesforce offers duplication management for this purpose.
You just set up Matching Rules and Duplicate Rules for your Account object in Setup > Administration Setup > Data.com Administration > Duplicate Management.
Link: https://help.salesforce.com/apex/HTViewHelpDoc?id=duplicate_prevention_map_of_tasks.htm&language=en_US
You could write a trigger to prevent duplicates. It'd be a "before insert" trigger that queried for existing accounts with the same name. If an Account name already exists, you'd call addError() on the new Account record, preventing the insert from continuing.
Have you searched the AppExchange for solutions? Might want to check out something like DupeCatcher
You could always make a custom field to contain the account name (something like "Business Name") and then ensure that's required and unique.
You'd need to do some basic Data Loader gymnastics to move your account names to the new field, and come up with a strategy for populating the existing Name field for accounts.
AND(VLOOKUP($ObjectType.Object_Name.Fields.Name, $ObjectType.Object_Name.Fields.Name, Name) = Name, OR(ISNEW(), ISCHANGED(Name)))

Elementary Apex Object IDs

Quick Question. In the below code, you can see that the for loop (which takes all of the records in newTimecards and puts them as a variable called timecard) and adds the Resource_c to the resourceIds set. I'm confused about how this object is considered an ID data type. When an object is made in Salesforce does it automatically have an ID made, so that it knows Resource_c ID can be added to a set? Note that within the Resource_c Object there is also a field called Resource_ID_c. Resource_c within Timecard_c is a Master-Detail data type. Resource_c is the parent of Timecard_c.
Now that I think about it, resourceIds.add(timecard.Resource_c), does that reference the relationship between the two objects and then searches through Resource_c and adds the ID field Resource_ID_c automactically since it's a unique field?
Thanks for your help.
public class TimecardManager {
public class TimecardException extends Exception {}
public static void handleTimecardChange(List<Timecard__c> oldTimecards,
List<Timecard__c> newTimecards) {
Set<ID> resourceIds = new Set<ID>();
for (Timecard__c timecard : newTimecards) {
resourceIds.add(timecard.Resource__c);
}
Every object instance (and that means EVERY, including factory ones) has a unique organization level ID, whose field name is always Id, is covered by Apex type ID and is a case-sensitive string of 15 characters that also has an 18 character case-insensitive representation. The first three characters are object prefix code (e.g. 500 for a Case) so all instances of the same object share the same prefix. You see these values all across SF (for example in https://na1.salesforce.com/02s7000000BW59L the 02s7000000BW59L in the URL is the ID). When an instance of the object is created using INSERT DML operation, the salesforce automatically assigns unique value based on the prefix and the next available transactional sub ID, it all happens transparently to you.
This is not to be confused with object Name field which is a field you define when you create an object and which can be auto-incremented and so on (e.g. MYOBJ-{00000}) and which can have more meaning to a user than a cryptic ID
When you create a lookup or master-detail relationship it is ID that is being used to link the two instances, not the Name. In the above example Resource__c seems to be that lookup field and it contains Id value of row's master.
What the code does is it enumerates all resources used in timelines and builds a set of their IDs, the purpose of which is most probably to be used via WHERE Id IN :resourceIds clause to load resource details from master table.
mmix's answer is a great overview to what an ID is and where it comes from. To answer what I think is your specific question:
Any time there is a reference from one object to another (like here, between Timecard_c and Resource_c), the field representing the reference will be an ID. So, the for loop that calls resourceIds.add(timecard.Resource__c) is just building up your set of ID's (those 15-character strings). The timecard.Resource__c doesn't look through the Resource__c table to find the ID, timecard.Resource__c is the ID.
