I have identified 3-5 keywords for every requirement in module-A. Each keyword is separated by a comma. Now I want to search every requirement in module-B to see which of them have words that match each of the key words.
Not sure exactly what you're looking for. You might have to specify if none of these solutions I'm about to propose are exactly what you're looking for.
If you're trying to create a filter which displays only objects with those keywords in your current view, you can create an advanced filter by first going to filter (Tools > Filter > Define) and then select the Advanced button on the bottom left of the filter menu that appears.
At this point you can create custom rules for the filter. I would just create an individual rule for each word with the following definition:
Attribute: Object Text
Condition: contains
Value: <insert word here>
Match Case: uncheck
Regular Expression: uncheck
Then select the Add button to add the rule to the list of available rules in the Advanced Options.
At this point you can select multiple rules in the list of available rules and you can AND/OR these rules together to create a custom filter for the view that you want.
So that's for if you're trying to create a custom view with just objects containing specific words.
If you're talking about writing DXL code to automatically spit out requirements that have a particular word in it. You can use the something that looks like this:
Object o
String s
int offset, len
for o in entire (current Module) do
{
if (isDeleted(o)) continue
s = o."Object Text"""
if findPlainText(s, "<insert word here>", offset, len, false)
{
print identifier(o) // or replace this line with however you want to display object
}
}
Hope this is helpful. Cheers!
Edit:
To perform actions on a comma separated list, one at a time, you can use a while loop with some sort of search function that cuts off words one at a time.
void processWord (string someWord, Module mTarget, Object oSource)
{
Object oTarget
string objID = identifier(oSource)
for oTarget in mTarget do
{
if (<someWord in oTarget Object Text>) // edit function as necessary to do this
{
if (oTarget."Exists""" == "")
oTarget."Exists" = objID
else
oTarget."Exists" = oTarget."Exists" "," objID
}
}
}
int offset, len
string searchCriteria
Module mSource = read("<path of source module>", true)
Module mTarget = edit("<path of target module>", true)
Object oSource
for oSource in mSource do // can use "for object in entire(m)" for all objects
{
if (oSource != rqmt) continue // create conditions specific to your module here
searchCriteria = oSource."Search Criteria"""
while (findPlainText(searchCriteria, ",", offset, len, false))
{
processWord(searchCriteria[0:offset-1], mTarget, oSource)
searchCriteria = searchCriteria[offset+1:]
}
}
processWord(searchCriteria, mTarget, oSource) // for last value in comma separated list

I am using BeanItemContainer for my Grid. I want to get a unique list of one of the properties. For instance, let's say my beans are as follows:
class Fun {
String game;
String rules;
String winner;
}
This would display as 3 columns in my Grid. I want to get a list of all the unique values for the game property. How would I do this? I have the same property id in multiple different bean classes, so it would be nice to get the values directly from the BeanItemContainer. I am trying to avoid building this unique list before loading the data into the Grid, since doing it that way would require me to handle it on a case by case basis.
My ultimate goal is to create a dropdown in a filter based on those unique values.
There isn't any helper for directly doing what you ask for. Instead, you'd have to do it "manually" by iterating through all items and collecting the property values to a Set which would then at the end contain all unique values.
Alternatively, if the data originates from a database, then you could maybe retrieve the unique values from there by using e.g. the DISTINCT keyword in SQL.
In case anyone is curious, this is how I applied Leif's suggestion. When they enter the dropdown, I cycle through all the item ids for the property id of the column I care about, and then fill values based on that property id. Since the same Grid can be loaded with new data, I also have to "clear" this list of item ids.
filterField.addFocusListener(focus->{
if(!(filterField.getItemIds() instanceof Collection) ||
filterField.getItemIds().isEmpty())
{
BeanItemContainer<T> container = getGridContainer();
if( container instanceof BeanItemContainer && getFilterPropertyId() instanceof Object )
{
List<T> itemIds = container.getItemIds();
Set<String> distinctValues = new HashSet<String>();
for(T itemId : itemIds)
{
Property<?> prop = container.getContainerProperty(itemId, getFilterPropertyId());
String value = null;
if( prop.getValue() instanceof String )
{
value = (String) prop.getValue();
}
if(value instanceof String && !value.trim().isEmpty())
distinctValues.add(value);
}
filterField.addItems(distinctValues);
}
}
});
Minor point: the filterField variable is using the ComboBoxMultiselect add-on for Vaadin 7. Hopefully, when I finally have time to convert to Vaadin 14+, I can do something similar there.
I am writing some DXL for use as a DXL column that for each object in a module, looks at the in-links and returns the link name. Then if the link name starts with "verif", it will get the object text from an attribute "TestResultFloating" in the linked module and show it in the current module, in the DXL column.
The problem I will have when I use this on the whole database (currently I am just using a sandbox) is that some of the modules linked through the "verif" link module will not contain the "TestResultFloating" attribute. For these I would like to oppress the 'unknown Object attribute (TestResultFloating)' error and instead display something like N/A for that Object in the current module.
Below is my code that currently works as long as the "TestResultFloating" attribute is present in the linked module, but will throw the error if the attribute is not present.
ModName_ mSrc
Object o = current
Object nObject
Object oSrc, oDest
LinkRef lr = null
Link l = null
string linkname = ""
string attrbName = "TestResultFloating"
for mSrc in (obj <- "*") do {
if (!open(mSrc)) {
read(fullName(mSrc), true)
}
}
for l in (obj <- "*") do {
oSrc = source(l)
linkname = name(module(l))
string linkmodname = upper(linkname[0:4])
if(linkmodname == "VERIF") {
string objText = oSrc."TestResultFloating"
display(objText)
}
}
I tried one way of doing it which I got from the dxl reference manual which was to check whether the attribute exists and then do the operation. This is what I added but it doesn't seem to work, I still get the same error "unknown Object attribute (TestResultFloating)"
What I tried is shown below:
if(linkmodname == "VERIF") {
if(exists attribute "TestResultFloating"){
string objText = oSrc."TestResultFloating"
display(objText)
}
else {
display("N/A")
}
}
Please also note that i'm very new to DOORS and DXL so if I am doing something drastically wrong or I am asking a simple question please forgive me.
There is a utility function called string probeAttr_(Object o, string attrName) that can be used for getting an attribute value if you are not sure whether the attribute is readable or whether it even exists.
This function and a lot of similar functions tailored for different circumstances can be found in the file "c:\Program Files\IBM\Rational\DOORS\9.6\lib\dxl\utils\attrutil.inc"
I have an MVC5 View where I am using the Grid.MVC component (https://gridmvc.codeplex.com/). This allows me to easily display data from my Oracle DB and has out of the box functionality for Sorting/Filtering each Data Column. What I am trying to implement now is a Wildcard Search across all fields in my grid. For example, if I search the number "2" I'd like to return all records that contain a "2" be they string, decimal, or DateTime.
The filter capability on this grid performs filtering (for individual columns) partially by modifying the URL (http://homeURL/?grid-filter=Location.DEPT__1__accounting) such as 1 being Equals, 2 being Contains, 3 being StartsWith, and 4 being EndsWith and then after the next 2 underscores being the search criteria.
I first thought I was going down the right path by using JavaScript to modify to the desired URL via daisy-chaining all fields with the search criteria using a CONTAINS. I then noticed that decimal fields like [Cost] and DateTime (Oracle DB) fields like [Acquired_Date] have criteria settings of Equals, Greater Than, and Less Than, so I tried:
$('#SearchIcon').on("click", function (e) {
window.location = window.location.href.substr(0, window.location.href.indexOf('?'));
window.location = "?grid-filter=FIELD1__2__" + document.getElementById("Search").value +
"&grid-filter=FIELD2__2__" + document.getElementById("Search").value +
"&grid-filter=COST__1__" + document.getElementById("Search").value +
// etc. -- ALL FIELDS
"&grid-filter=NOTE__2__" + document.getElementById("Search").value;
});
This technically functions, but with the [&] is searching for a record(s) that have the corresponding search criteria in EVERY field. What I need is something similar, but with an OR [||] conditioning ---- unfortunately the grid component does not contain this form of functionality.
I then thought to pass the search criteria to a controller action and use it via a multi-WHERE clause and return only the records fitting the filter to my View:
public ActionResult SearchAssets(string searchCriteria)
{
fillPagingIntervalList();
var assetSearchResults = db.ENTITY_COLLECTION.Where(m => m.ID.ToString() == searchCriteria ||
m.Model.ToString() == searchCriteria ||
m.COST.ToString() == searchCriteria ||
// etc. -- ALL FIELDS
).FirstOrDefault();
var assetCount = db.ENTITY_COLLECTION.ToList().Count();
return View(assetSearchResults);
}
This resulted in an error with the WHERE cluase, stating to view the Inner Exception for details -- ORA-12704: character set mismatch MVC. I then reduced my multiple conditions down to just 2 fields to be searched for debugging:
var assetSearchResults = db.ENTITY_COLLECTION.Where(m => m.ID.ToString() == searchCriteria ||
m.Model.ToString() == searchCriteria).FirstOrDefault();
Resulting in:
EntityCommandExecutionException was unhandled by user code.
An exception of type 'System.Data.Entity.Core.EntityCommandExecutionException' occurred in EntityFramework.dll but was not handled in user code
Additional information: An error occurred while executing the command definition. See the inner exception for details.
Inner Exception: ORA-00932: inconsistent datatypes: expected - got NCLOB
Anyone have an idea on how to get what I want working? I also tried .Where(...con1...).Where(...con2...).Where(...etc...) with the same error resulting. I figured a wildcard search across all fields would be difficult to implement, but this is proving to be a whole bigger animal than I anticipated.
This will be very slow, but try this, which will load the entire collection into objects and let LINQ do the filtering on the client side:
public ActionResult SearchAssets(string searchCriteria)
{
fillPagingIntervalList();
var assetSearchResults = db.ENTITY_COLLECTION.ToList().Where(m => m.ID.ToString() == searchCriteria ||
m.Model.ToString() == searchCriteria ||
m.COST.ToString() == searchCriteria ||
// etc. -- ALL FIELDS
).FirstOrDefault();
var assetCount = db.ENTITY_COLLECTION.ToList().Count();
return View(assetSearchResults);
}
You could try something like this:
public ActionResult SearchAssets(string searchCriteria)
{
fillPagingIntervalList();
var assetSearchResults = db.ENTITY_COLLECTION.Where(m => m.ID.ToString() == searchCriteria)
.Union(db.ENTITY_COLLECTION.Where(m =>m.Model.ToString()==searchCriteria))
.Union(db.ENTITY_COLLECTION.Where(m =>m.COST.ToString() == searchCriteria))
// etc. -- ALL FIELDS
var assetCount = db.ENTITY_COLLECTION.ToList().Count();
return View(assetSearchResults);
}
Although, ultimately I would suggest looking into something like a predicate builder. Seems to be what you are doing anyhow.
so I have a form with several fields which are criteria for searching in a database.
I want to formulate a query using LINQ like so:
var Coll = (from obj in table where value1 = criteria1 && value2 = criteria2...)
and so on.
My problem is, I don't want to write it using If statements to check if every field has been filled in, nor do I want to make separate methods for the various search cases (criteria 1 and criteria 5 input; criteria 2 and criteria 3 input ... etc.)
So my question is: How can I achieve this without writing an excessive amount of code? If I just write in the query with comparison, will it screw up the return values if the user inputs only SOME values?
Thanks for your help.
Yes, it will screw up.
I would go with the ifs, I don't see what's wrong with them:
var query = table;
if(criteria1 != null)
query = query.Where(x => x.Value1 == criteria1);
if(criteria2 != null)
query = query.Where(x => x.Value2 == criteria2);
If you have a lot of criteria you could use expressions, a dictionary and a loop to cut down on the repetitive code.
In an ASP.NET MVC app, chances are your user input is coming from a form which is being POSTed to your server. In that case, you can make use of strongly-typed views, using a viewmodel with [Required] on the criteria that MUST be provided. Then you wrap your method in if (ModelState.IsValid) { ... } and you've excluded all the cases where the user hasn't given you something they need.
Beyond that, if you can collect your criteria into a list, you can filter it. So, you could do something like this:
filterBy = userValues.Where(v => v != null);
var Coll = (from obj in table where filterBy.Contains(value1) select obj);
You can make this more complex by having a Dictionary (or Lookup for non-unique keys) that contains a user-entered value along with some label (an enum, perhaps) that tells you which field they're filtering by, and then you can group them by that label to separate out the filters for each field, and then filter as above. You could even have a custom SearchFilter object that contains other info, so you can have filters with AND, NOT and OR conditions...
Failing that, you can remember that until you trigger evaluation of an IQueryable, it doesn't hit the database, so you can just do this:
var Coll = (from obj in table where value1 == requiredCriteria select obj);
if(criteria1 != null)
{
query = query.Where(x => x.Value1 == criteria1);
}
//etc...
if(criteria5 != null)
{
query = query.Where(x => x.Value5 == criteria5);
}
return query.ToList();
That first line applies any criteria that MUST be there; if there aren't any mandatory ones then it could just be var Coll = table;.
That will add any criteria that are provided will be applied, any that aren't will be ignored, you catch all the possible combinations, and only one query is made at the end when you .ToList() it.
As I understand of your question you want to centralize multiple if for the sake of readability; if I were right the following would be one of some possible solutions
Func<object, object, bool> CheckValueWithAnd = (x, y) => x == null ? true : x==y;
var query = from obj in table
where CheckValue(obj.value1, criteria1) &&
CheckValue(obj.value2, criteria2) &&
...
select obj;
It ls flexible because in different situations or scenarios you can change the function in the way that fulfill your expectation and you do not need to have multiple if.
If you want to use OR operand in your expression you need to have second function
Func<object, object, bool> CheckValueWithOr = (x, y) => x == null ? false : x==y;
I am trying to iterate over a list of parameters, in a grails controller. when I have a list, longer than one element, like this:
[D4L2DYJlSw, 8OXQWKDDvX]
the following code works fine:
def recipientId = params.email
recipientId.each { test->
System.print(test + "\n")
}
The output being:
A4L2DYJlSw
8OXQWKDDvX
But, if the list only has one item, the output is not the only item, but each letter in the list. for example, if my params list is :
A4L2DYJlSwD
using the same code as above, the output becomes:
A
4
L
2
D
Y
J
l
S
w
can anyone tell me what's going on and what I am doing wrong?
thanks

I run at the same problem a while ago! My solution for that it was
def gameId = params.gameId
def selectedGameList = gameId.class.isArray() ? Game.getAll(gameId as List) : Game.get(gameId);
because in my case I was getting 1 or more game Ids as parameters!
What you can do is the same:
def recipientId = params.email
if(recipientId.class.isArray()){
// smtg
}else{
// smtg
}
Because what is happening here is, as soon as you call '.each' groovy transform that object in a list! and 'String AS LIST' in groovy means char_array of that string!
My guess would be (from what I've seen with groovy elsewhere) is that it is trying to figure out what the type for recipientId should be since you haven't given it one (and it's thus dynamic).
In your first example, groovy decided what got passed to the .each{} closure was a List<String>. The second example, as there is only one String, groovy decides the type should be String and .each{} knows how to iterate over a String too - it just converts it to a char[].
You could simply make recipientId a List<String> I think in this case.
You can also try like this:
def recipientId = params.email instanceof List ? params.email : [params.email]
recipientId.each { test-> System.print(test + "\n") }
It will handle both the cases ..
Grails provides a built-in way to guarantee that a specific parameter is a list, even when only one was submitted. This is actually the preferred way to get a list of items when the number of items may be 0, 1, or more:
def recipientId = params.list("email")
recipientId.each { test->
System.print(test + "\n")
}
The params object will wrap a single item as a list, or return the list if there is more than one.
