I have an OData model with a property column 'category'. In twenty rows are i. e. 3 different categories. Now I want to display a list of all different categories to use as filter for a table. How can I do that?
Thanks
I started to answer this earlier today but then didnt complete it as it may not be a full answer but this certainly is a good place to start...
Two options I guess: get a function import that just returns a set of the categories and push the problem to the server.
Or process on the client side by using reduce on the column in question.
The best way to do that is explained here.
So adapting that answer:
var categories = ["SAPUI5","OpenUI5","JavaScript","NodeJS","SAP HANA","JavaScript","SAPUI5"];
var uniq = categories.reduce(function (a,b) {
if (a.indexOf(b) < 0 ) a.push(b);
return a;
}, []);
console.log(uniq); // ["SAPUI5", "OpenUI5", "JavaScript", "NodeJS", "SAP HANA"]

How do I take a list of values, iterate through it to create the needed objects then pass that "list" of objects to the API to create multiple rows?
I have been successful in adding a new row with a value using the API example. In that example, two objects are created.
row_a = ss_client.models.Row()
row_b = ss_client.models.Row()
These two objects are passed in the add row function. (Forgive me if I use the wrong terms. Still new to this)
response = ss_client.Sheets.add_rows(
2331373580117892, # sheet_id
[row_a, row_b])
I have not been successful in passing an unknown amount of objects with something like this.
newRowsToCreate = []
for row in new_rows:
rowObject = ss.models.Row()
rowObject.cells.append({
'column_id': PM_columns['Row ID Master'],
'value': row
})
newRowsToCreate.append(rowObject)
# Add rows to sheet
response = ss.Sheets.add_rows(
OH_MkrSheetId, # sheet_id
newRowsToCreate)
This returns this error:
{"code": 1062, "errorCode": 1062, "message": "Invalid row location: You must
use at least 1 location specifier.",
Thank you for any help.
From the error message, it looks like you're missing the location specification for the new rows.
Each row object that you create needs to have a location value set. For example, if you want your new rows to be added to the bottom of your sheet, then you would add this attribute to your rowObject.
rowObject.toBottom=True
You can read about this location specific attribute and how it relates to the Python SDK here.
To be 100% precise here I had to set the attribute differently to make it work:
rowObject.to_bottom = True
I've found the name of the property below:
https://smartsheet-platform.github.io/smartsheet-python-sdk/smartsheet.models.html#module-smartsheet.models.row
To be 100% precise here I had to set the attribute differently to make it work:
Yep, the documentation isn't super clear about this other than in the examples, but the API uses camelCase in Javascript, but the same terms are always in snake_case in the Python API (which is, after all, the Pythonic way to do it!)
I am using a row id to obtain the cells for a single row. However, the response returns the column id but not the title of the column. In an attempt to make the code readable for others it would be helpful to also obtain the column title. I was thinking of doing this by using the column id that is obtained in the getRow function but I am not entirely sure how to catch it. Below is the basic getRow function for reference. I appreciate any assistance. Thank you in advance all.
smartsheet.sheets.getRow(options)
.then(function(row) {
console.log(row);
})
.catch(function(error) {
console.log(error);
});
My preferred way of addressing this is to dynamically create a column map on my first GET /sheets/{sheetId} request.
Let's say we have a sheet with three columns: Japan, Cat, and Cafe. Here is one way to make a column map.
const columnMap = makeColumnMap(<your sheet data>);
function makeColumnMap(sheetData){
const colMap = {};
sheetData.columns.map( column => colMap[column.title] = column.id);
return colMap;
}
Now, you can reference your specific columns like this: columnMap["Japan"], columnMap["Cat"], and columnMap["Cafe"] or you can use dot notation if you prefer.
Basically, what we're doing is creating a dictionary to map the column titles to the corresponding column id.
Posting this as a separate answer based on your response (and for easier formatting).
I have a couple specific recommendations that will help you.
Try to consolidate your API calls.
I then want to use that columnID to call getColumns(columnId) to obtain the title.
This is 'work' that you don't need to do. A single GET /sheets/{sheetId} will include all the data you need in one call. It's just a matter of parsing the JSON response.
Use this as an opportunity to improve your ability to work with JSON.
I do not know how to catch the columnId once getRow() is called.
The response is a single object with nested arrays and objects. Learning to navigate the JSON in a way that makes sense to you will come in really handy.
I would recommend saving the response from a GET sheet call as it's own JSON file. From there, you can bring it into your script and play with your logic to reference the values you want.
I have two Seq[_]es in my Play application.
Now I want to make a diff of those and get as a result an Seq with all items which are not in the other one.
I tried to use .filter() but I don't know if thats a good way
How can I achieve this?
thanks in advance
Update ... PseudoCode Example
I have two Seq[]
1.) Seq[CarsInStock]
Attributes[ID, Brand, Color]
[{1,Porsche,Red},{3,Mercedes,Blue}]
2.) Seq[CarsAfterSale]
Attributes[ID, Brand, Color,Doors,Windows]
[{1,Porsche,Red,4,10}]
Now I wan't to make a diff between the two seq[]. As result I want to get the Object {3,Mercedes,Blue}] because it is in stock, but after sales I have to know which ones I have to remove from stock.
I want to recognize the difference by the ID of the elements
You can simply filter out all cars whose id exist in the other Seq.
stock.filterNot(c => afterSale.exists(_.id == c.id))
Unless you expect the second Seq to be short, you can probably optimize it by creating a Set of ids:
val afterSaleIds = afterSale.iterator.map(_.id).toSet
stock.filterNot(c => afterSaleIds.contains(c.id))
How does one use Firebase to do basic auto-completion/text preview?
For example, imagine a blog backed by Firebase where the blogger can tag posts with tags. As the blogger is tagging a new post, it would be helpful if they could see all currently-existing tags that matched the first few keystrokes they've entered. So if "blog," "black," "blazing saddles," and "bulldogs" were tags, if the user types "bl" they get the first three but not "bulldogs."
My initial thought was that we could set the tag with the priority of the tag, and use startAt, such that our query would look something like:
fb.child('tags').startAt('bl').limitToFirst(5).once('value', function(snap) {
console.log(snap.val())
});
But this would also return "bulldog" as one of the results (not the end of the world, but not the best either). Using startAt('bl').endAt('bl') returns no results. Is there another way to accomplish this?
(I know that one option is that this is something we could use a search server, like ElasticSearch, for -- see https://www.firebase.com/blog/2014-01-02-queries-part-two.html -- but I'd love to keep as much in Firebase as possible.)
Edit
As Kato suggested, here's a concrete example. We have 20,000 users, with their names stored as such:
/users/$userId/name
Oftentimes, users will be looking up another user by name. As a user is looking up their buddy, we'd like a drop-down to populate a list of users whose names start with the letters that the searcher has inputted. So if I typed in "Ja" I would expect to see "Jake Heller," "jake gyllenhaal," "Jack Donaghy," etc. in the drop-down.
I know this is an old topic, but it's still relevant. Based on Neil's answer above, you more easily search doing the following:
fb.child('tags').startAt(queryString).endAt(queryString + '\uf8ff').limit(5)
See Firebase Retrieving Data.
The \uf8ff character used in the query above is a very high code point
in the Unicode range. Because it is after most regular characters in
Unicode, the query matches all values that start with queryString.
As inspired by Kato's comments -- one way to approach this problem is to set the priority to the field you want to search on for your autocomplete and use startAt(), limit(), and client-side filtering to return only the results that you want. You'll want to make sure that the priority and the search term is lower-cased, since Firebase is case-sensitive.
This is a crude example to demonstrate this using the Users example I laid out in the question:
For a search for "ja", assuming all users have their priority set to the lowercased version of the user's name:
fb.child('users').
startAt('ja'). // The user-inputted search
limitToFirst(20).
once('value', function(snap) {
for(key in snap.val()){
if(snap.val()[key].indexOf('ja') === 0) {
console.log(snap.val()[key];
}
}
});
This should only return the names that actually begin with "ja" (even if Firebase actually returns names alphabetically after "ja").
I choose to use limitToFirst(20) to keep the response size small and because, realistically, you'll never need more than 20 for the autocomplete drop-down. There are probably better ways to do the filtering, but this should at least demonstrate the concept.
Hope this helps someone! And it's quite possible the Firebase guys have a better answer.
(Note that this is very limited -- if someone searches for the last name, it won't return what they're looking for. Hence the "best" answer is probably to use a search backend with something like Kato's Flashlight.)
It strikes me that there's a much simpler and more elegant way of achieving this than client side filtering or hacking Elastic.
By converting the search key into its' Unicode value and storing that as the priority, you can search by startAt() and endAt() by incrementing the value by one.
var start = "ABA";
var pad = "AAAAAAAAAA";
start += pad.substring(0, pad.length - start.length);
var blob = new Blob([start]);
var reader = new FileReader();
reader.onload = function(e) {
var typedArray = new Uint8Array(e.target.result);
var array = Array.prototype.slice.call(typedArray);
var priority = parseInt(array.join(""));
console.log("Priority of", start, "is:", priority);
}
reader.readAsArrayBuffer(blob);
You can then limit your search priority to the key "ABB" by incrementing the last charCode by one and doing the same conversion:
var limit = String.fromCharCode(start.charCodeAt(start.length -1) +1);
limit = start.substring(0, start.length -1) +limit;
"ABA..." to "ABB..." ends up with priorities of:
Start: 65666565656565650000
End: 65666665656565650000
Simples!
Based on Jake and Matt's answer, updated version for sdk 3.1. '.limit' no longer works:
firebaseDb.ref('users')
.orderByChild('name')
.startAt(query)
.endAt(`${query}\uf8ff`)
.limitToFirst(5)
.on('child_added', (child) => {
console.log(
{
id: child.key,
name: child.val().name
}
)
})
I want to build kind of an automatic system to update some race results for a championship. I have an automated spreadsheet were all the results are shown but it takes me a lot to update all of them so I was wondering if it would be possible to make a form in order to update them more easily.
In the form I will enter the driver name and the number o points he won on a race. The championship has 4 races each month so yea, my question is if you guys know a way to update an existing data (stored in a spreadsheet) using a form. Lets say that in the first race, the driver 'X' won 10 points. I will insert this data in a form and then call it from the spreadsheet to show it up, that's right. The problem comes when I want to update the second race results and so on. If the driver 'X' gets on the second race 12 points, is there a way to update the previous 10 points of that driver and put 22 points instead? Or can I add the second race result to the first one automatically? I mean, if I insert on the form the second race results can it look for the driver 'X' entry and add this points to the ones that it previously had. Dunno if it's possible or not.
Maybe I can do it in another way. Any help will be much appreciated!
Thanks.
Maybe I missed something in your question but I don't really understand Harold's answer...
Here is a code that does strictly what you asked for, it counts the total cumulative value of 4 numbers entered in a form and shows it on a Spreadsheet.
I called the 4 questions "race number 1", "race number 2" ... and the result comes on row 2 so you can setup headers.
I striped out any non numeric character so you can type responses more freely, only numbers will be retained.
form here and SS here (raw results in sheet1 and count in Sheet2)
script goes in spreadsheet and is triggered by an onFormSubmit trigger.
function onFormSubmit(e) {
var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet2');
var responses = []
responses[0] = Number(e.namedValues['race number 1'].toString().replace(/\D/g,''));
responses[1] = Number(e.namedValues['race number 2'].toString().replace(/\D/g,''));
responses[2] = Number(e.namedValues['race number 3'].toString().replace(/\D/g,''));
responses[3] = Number(e.namedValues['race number 4'].toString().replace(/\D/g,''));
var totals = sh.getRange(2,1,1,responses.length).getValues();
for(var n in responses){
totals[0][n]+=responses[n];
}
sh.getRange(2,1,1,responses.length).setValues(totals);
}
edit : I changed the code to allow you to change easily the number of responses... range will update automatically.
EDIT 2 : a version that accepts empty responses using an "if" condition on result:
function onFormSubmit(e) {
var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet2');
var responses = []
responses[0] = Number((e.namedValues['race number 1']==null ? 0 :e.namedValues['race number 1']).toString().replace(/\D/g,''));
responses[1] = Number((e.namedValues['race number 2']==null ? 0 :e.namedValues['race number 2']).toString().replace(/\D/g,''));
responses[2] = Number((e.namedValues['race number 3']==null ? 0 :e.namedValues['race number 3']).toString().replace(/\D/g,''));
responses[3] = Number((e.namedValues['race number 4']==null ? 0 :e.namedValues['race number 4']).toString().replace(/\D/g,''));
var totals = sh.getRange(2,1,1,responses.length).getValues();
for(var n in responses){
totals[0][n]+=responses[n];
}
sh.getRange(2,1,1,responses.length).setValues(totals);
}
I believe you can found everything you want here.
It's a form url, when you answer this form you'll have the url of the spreadsheet where the data are stored. One of the information stored is the url to modify your response, if you follow the link it will open the form again and update the spreadsheet in consequence. the code to do this trick is in the second sheet of the spreadsheet.
It's a google apps script code that need to be associated within the form and triggered with an onFormSubmit trigger.
It may be too late now. I believe we need a few things (I have not tried it)
A unique key to map each submitted response, such as User's ID or email.
Two Google Forms:
a. To request the unique key
b. To retrieve relevant data with that unique key
Create a pre-filled URL (See http://www.cagrimmett.com/til/2016/07/07/autofill-google-forms.html)
Open the URL from your form (See Google Apps Script to open a URL)
