I have a publication, essentially what's below:
Meteor.publish('entity-filings', function publishFunction(cik, queryArray, limit) {
if (!cik || !filingsArray)
console.error('PUBLICATION PROBLEM');
var limit = 40;
var entityFilingsSelector = {};
if (filingsArray.indexOf('all-entity-filings') > -1)
entityFilingsSelector = {ct: 'filing',cik: cik};
else
entityFilingsSelector = {ct:'filing', cik: cik, formNumber: { $in: filingsArray} };
return SB.Content.find(entityFilingsSelector, {
limit: limit
});
});
I'm having trouble with the filingsArray part. filingsArray is an array of regexes for the Mongo $in query. I can hardcode filingsArray in the publication as [/8-K/], and that returns the correct results. But I can't get the query to work properly when I pass the array from the router. See the debugged contents of the array in the image below. The second and third images are the client/server debug contents indicating same content on both client and server, and also identical to when I hardcode the array in the query.
My question is: what am I missing? Why won't my query work, or what are some likely reasons it isn't working?
In that first screenshot, that's a string that looks like a regex literal, not an actual RegExp object. So {$in: ["/8-K/"]} will only match literally "/8-K/", which is not the same as {$in: [/8-K/]}.
Regexes are not EJSON-able objects, so you won't be able to send them over the wire as publish function arguments or method arguments or method return values. I'd recommend sending a string, then inside the publish function, use new RegExp(...) to construct a regex object.
If you're comfortable adding new methods on the RegExp prototype, you could try making RegExp an EJSON-able type, by putting this in your server and client code:
RegExp.prototype.toJSONValue = function () {
return this.source;
};
RegExp.prototype.typeName = function () {
return "regex";
}
EJSON.addType("regex", function (str) {
return new RegExp(str);
});
After doing this, you should be able to use regexes as publish function arguments, method arguments and method return values. See this meteorpad.
/8-K/.. that's a weird regex. Try /8\-K/.
A minus (-) sign is a range indicator and usually used inside square brackets. The reason why it's weird because how could you even calculate a range between 8 and K? If you do not escape that, it probably wouldn't be used to match anything (thus your query would not work). Sometimes, it does work though. Better safe than never.
/8\-K/ matches the string "8-K" anywhere once.. which I assume you are trying to do.
Also it would help if you would ensure your publication would always return something.. here's a good area where you could fail:
if (!cik || !filingsArray)
console.error('PUBLICATION PROBLEM');
If those parameters aren't filled, console.log is probably not the best way to handle it. A better way:
if (!cik || !filingsArray) {
throw "entity-filings: Publication problem.";
return false;
} else {
// .. the rest of your publication
}
This makes sure that the client does not wait unnecessarily long for publications statuses as you have successfully ensured that in any (input) case you returned either false or a Cursor and nothing in between (like surprise undefineds, unfilled Cursors, other garbage data.

I'm starting to learn about mongoose/MongoDB aggregation functions, and am having some basic difficulties. For example, I'm trying to do the following:
var myModels= require('./models/myModel');
var myCount = myModels.countDocuments({userID: "A"});
console.log(myCount );
I just want to count the number of documents with userID of "A" but when this prints to the console, it's printing as a whole object, instead of just a numerical count. I've read the answer here but I'm still not able to solve this problem (also, is there a way, unlike in that question, to return the count directly rather than having to predefine a variable and set it in a callback function?)
I'm trying to follow the guide here and don't see where I'm going wrong.
It's because the return value of countDocuments is a promise and not a number.
You either need to wait for that Promise or use callback syntax like so:
var myModels= require('./models/myModel');
// this required the code to be inside an async function
var myCount = await myModels.countDocuments({userID: "A"});
console.log(myCount);
Or:
var myModels= require('./models/myModel');
myModels.countDocuments({userID: "A"})
.then((myCount) =>{console.log(myCount);});
I am writing a test which should iterate until a partial matching text is found . Once found , it should do some thing. Here is my code.
let getName = await $$('.button').getText();
if (getName === 'New name') {
// do something here
}
My test doesn't iterate even though there exists a matching name. It should also consider partials tests, for instance New name 1.
Appreciate your suggestions.
My answer is a shot in a dark due to lack of details in your question, but I'll try to guess your problem.
$$().getText() returns array of strings, thus your code must be
let names = await $$('.button').getText();
for (let i=0; i<names.length; i++) {
if (names[i].includes('New name')) {
// do something here
}
}
But when you await $$().getText(), and there are more than ~10 elements, be ready to face this error Random occurrences of Failed: ECONNREFUSED connect ECONNREFUSED 127.0.0.1 when running protractor tests
Actually, I must include another guess here based on an assumption you'll need to interact with the first element that matches condition
let $newNameElement = await $$('.button').filter( $elem =>
(await $elem.getText()).toLowerCase().includes('new name');
).get(0);
// do whatever you want with your $newNameElement
I've read all the documentation I can find and watched all the videos I can find and don't understand how to do this. I have set up an xPages REST Service and it works well. Now I want to place the results of the service into either a combobox or typeahead text field. Ideally I would like to know how to do it for both types of fields.
I have an application which has a view containing a list of countries, another view containing a list of states, and another containing a list of cities. I would like the first field to only display the countries field from the list of data it returns in the XPages REST Service. Then, depending upon which country was selected, I would like the states for that country to be listed in another field for selection, etc.
I can see code for calling the REST Service results from a button, or from a dojo grid, but I cannot find how to call it to populate either of the types of fields identified above.
Where would I call the Service for the field? I had thought it would go in the Data area, but perhaps I've just not found the right syntax to use.
November 6, 2017:
I have been following your suggestion, but am still lost as can be. Here's what I currently have in my code:
x$( "#{id:ApplCountry}" ).select2({
placeholder: "select a country",
minimumInputLength: 2,
allowClear : true,
multiple: false,
ajax: {
dataType: 'text/plain',
url: "./Application.xsp/gridData",
quietMillis: 250,
data: function (params) {
return {
search:'[name=]*'+params.term+'*',
page: params.page
};
},
processResults: function (data, page) {
var data = $.map(data, function (obj) {
obj.id = obj.id || obj["#entityid"];
obj.text = obj.text || obj.name;
return obj;
});
},
return {results: data};
}
}
});
I'm using the dataType of 'text/plain' because that was what I understood I should use when gathering data from a domino application. I have tried changing this to json but it makes no difference.
I'm using processResults because I understand this is what should be used in version 4 of select2.
I don't understand the whole use of the hidden field, so I've stayed away from that.
No matter what I do, although my REST service works if I put it directly in the url, I cannot get any data to display in the field. All I want to display in the field is the country code of the document, which is in the field named "name" (not my choice, it's how it came before I imported the data from MySQL.
I have read documentation and watched videos, but still don't really understand how everything fits together. That was my problem with the REST service. If you use it in Dojo, you just put the name of the service in a field on the Dojo element and it's done, so I don't understand why all the additional coding for another type of domino element. Shouldn't it work the same way?
I should point out that at some points it does display the default message, so it does find the field. Just doesn't display the country selections.
I think the issue may be that you are not returning SelectItems to your select2, and that is what it is expecting. When I do something like you are trying, I actually use a bean to generate the selection choices. You may want to try that or I'm putting in the working part of my bean below.
The Utils.getItemValueAsString is a method I use to return either the string value of a field, or if it is not on the document/empty/null an empty string. I took out an if that doesn't relate to this, so there my be a mismatch, but I hope not.
You might be able to jump directly to populating the arrayList, but as I recall I needed to leverage the LinkedHashMap for something.
You should be able to do the same using SSJS, but since that renders to Java before executing, I find this more efficient.
For label/value pairs:
LinkedHashMap lhmap = new LinkedHashMap();
Document doc = null;
Document tmpDoc = null;
allObjects.addElement(doc);
if (dc.getCount() > 0) {
doc = dc.getFirstDocument();
while (doc != null) {
lhmap.put(Utils.getItemValueAsString(doc, LabelField, true), Utils.getItemValueAsString(doc, ValueField, true));
}
tmpDoc = dc.getNextDocument(doc);
doc.recycle();
doc = tmpDoc;
}
}
List<SelectItem> options = new ArrayList<SelectItem>();
Set set = lhmap.entrySet();
Iterator hsItr = set.iterator();
while (hsItr.hasNext()) {
Map.Entry me = (Map.Entry) hsItr.next();
// System.out.println("after: " + hStr);
SelectItem option = new SelectItem();
option.setLabel(me.getKey() + "");
option.setValue(me.getValue() + "");
options.add(option);
}
System.out.println("About to return from generating");
return options;
}
I ended up using straight up SSJS. Worked like a charm - very simple.
I am writing a protractor test case to compare the name(s) of the displayed data is same as the searched name.
Even though my test case works fine, I am not able to understand what is happening. Because when i expect the name to compare, it compares as expected, but when i print the elementFinder's(rowData)(i have attached the output screen shot here) value in console.log, it show a huge list of some values which i am not able to understand?
PS: I am a newbie to protractor`
This is the testCase:
it('should show proper data for given last name', function () {
var searchValue='manning';
searchBox.sendKeys(searchValue);
search.click();
element.all(by.binding('row.loanNumber')).count().then(function(value) {
var loanCount = value;
for (var i = 0; i < loanCount; i++) {
var rowData = element.all(by.binding('row.borrowerName')).get(i).getText();
expect(rowData).toMatch(searchValue.toUpperCase());
console.log(rowData,'*****',searchValue.toUpperCase());
}
});
});`
And give me valuable suggestions about my style of code
rowData is a promise (not a value), so when you console.log it, you get the promise object
Protractor patches Jasmine to automatically resolve promises within the expect(), so that's how it knows to resolve the value and compare to the expected result.
If you want to console.log the value, you need to resolve the promise with .then() to get the value.
rowData.then(function(rowDataText) {
console.log(rowDataText);
)}
This is pretty much everyone's first question when they start using protractor. You will want to learn how promises work if you want a good understanding of how to manipulate them.
I am new to jayData and am trying to filter on an entity set. The filter needs to perform an complex evaluation beyond what I saw in the samples.
Here is a working sample of what I am trying to accomplish (the listView line isn't and is just there to show what I plan to do with the data):
function () {
var weekday = moment().isoWeekday()-1;
console.log(weekday);
var de = leagueDB.DailyEvents.toArray(function (events) {
console.log(events);
var filtered = [];
for (var e = 0; e < events.length;e++) {
console.log(events[e]);
console.log(events[e].RecurrenceRule);
var rule = RRule.fromString(events[e].RecurrenceRule);
var ruleOptions = rule.options.byweekday;
var isDay = ruleOptions.indexOf(weekday);
console.log(ruleOptions, isDay);
if(isDay =! -1)
{
filtered.push(events[e]);
}
}
$("#listView").kendoListView({dataSource:filtered});
});
Basically it is just evaluating a recurring rule string to see if the current day meets that criteria, if so add that event to the list for viewing.
But it blows up when I try to do this:
eventListLocal:leagueDB.DailyEvents.filter(function(e){
console.log("The Weekday is:"+viewModel.weekday);
console.log(e);
console.log("The recurrence rule is:"+e.RecurrenceRule);
var rruleOptions = viewModel.rruleOptions(e.RecurrenceRule);
if (rruleOptions !== -1) {
return true;
}
}).asKendoDataSource()
The error that is generating is:
Exception: Unable to resolve type:undefined
The thing is it seems to be occurring on "e" and the console logs like the event is not being passed in. However, I am not seeing a list either. In short I am really confused as to what is going on.
Any help would be appreciated.
Thanks,
You can't write filter expressions such as this.
When you write .filter(...), jaydata will parse your expression and then it will generate filter for underlying provider, for example where for webSql and $filter for oDataProvider.
Both JayData expression parser and the data provider itself should understand your filter.
Your filter is not suitable for this approach, because most of your codes are not familiar for jaydata expression parser and the underlying data provider, for example your console.log etc.
You can simplify your filter, or you should load all your data into an array, and then you can use filter method of array itself, there, you can write any filter you like, and your filter will work. Of course this has performance issue in some scenarios when your data set is large.
