After doing a Fb.AppRequest, in my callback, I try to parse out how many users where invited by the user doing the invitation.
The problem I'm having, is that I'm parsing my result as follows:
var responseObject = Json.Deserialize(result.Text) as Dictionary<string, object>;
and when I try to access the "to" parameter, I cant get the value as an array. I tried the following, but it didnt work either.
object obj = 0;
if (responseObject.TryGetValue ("to", out obj))
{
Debug.Log("Sent to: " + ((string[])obj).Length);
}
Any help on how I can get the amount of users to which I sent the invite to?
Thanks a lot
If you only need to know how many objects do you have, you can cast that object to an IEnumerable for example:
IEnumerable<object> obj = (IEnumerable<object>)responseObject["to"];
int count = obj.Count();
or something like that.
Hope that helps !

simple question here but wondering if anyone can offer the right solution.
I want to take in an object of the same type as my current class, and set all my fields to that object's fields, without individually setting each out. Is there a way to do that easily or no?
Eg.,
User({required this.uid}) {
Database().getUser(uid).listen((User user) async {
displayName = user?.displayName;
email = user?.email;
phoneNumber = user?.phoneNumber;
photoURL = user?.photoURL;
notifyListeners();
});
}
The above works but isn't clean.
I want to be able to do the above in 1 line, eg., set
this.user = user
Not sure if this is possible. Thanks!
I am trying to creating a app which can send posts to tumblr using tumblr.js api.
I could send single image using the createPhotoPost method, but I have to send multiple image in a single post via this method.
From the documentation it says that createPhotoPost method has a "data" parameter which can be an array with "URL-encoded binary contents"
When ever I try to send something in the data Array it returns "[Error: form-data: Arrays are not supported.]".
Can someone please help to solve this issue and please explain what should we pass in the array (Really I am not getting what is URL-encoded binary contents)?
Thanks in advance
There is an error in tumblr.js
https://tumblr.github.io/tumblr.js/tumblr.js.html#line504
The documentation at https://www.tumblr.com/docs/en/api/v2#posting is correct.
Basically the issue is that its not supposed to be
data = [ one , two ] its litterally params['data[0]'] = one ; params['data[1]'] = two; (?A PHP Convention)
var request = require('request')// already a tumblr.js dependency
var currentRequest = request({
url:'https://api.tumblr.com/v2/blog/someblog.tumblr.com/post',
oauth:keys,
},function(err,response,body){
currentRequest//
debugger
cb()
})
var params = {
'type' :'photo',
'caption':'Click To Verify You Are A Robot',
}
var params_images = [
fs.createReadStream('image'),
fs.createReadStream('image')
]
// Sign it with the non-data parameters
currentRequest.form(params)
currentRequest.oauth(keys);
// Clear the side effects from form(param)
delete currentRequest.headers['content-type'];
delete currentRequest.body;
// And then add the full body
var form = currentRequest.form();
//###add params_images to params keys 'data[0]' 'data[1]' 'data[2]' ....
params_images.forEach(function(image,index){
params['data['+index+']']
})
for (var key in params) {
form.append(key, params[key]);
}
// Add the form header back
var form_headers = form.getHeaders()
for(var key in form_headers){
currentRequest[key] = form_headers[key]
}
I have never done it before and now when the need arise, things are not working.
I have to send an ID to delete a DB record with RESTful service. Here is the code I am trying:
<cfhttp url="http://127.0.0.1:8500/rest/test/something" method="DELETE" port="8500" result="qryRes1">
<cfhttpparam type="body" value="36"/>
</cfhttp>
and in the REST function
remote any function someName() httpmethod="DELETE"{
var testID = ToString(getHTTPRequestData().content);
//make db call to delete
return testid;
}
The result comes as blank [empty string]. I am not able to retrieve the sent value in function. What I am missing?
Edit: one slightly different but related to CF rest, is it necessary to convert query to an array before sending it back to client? Directly serializing won't solve the purpose same way?
you may want to take a look at deleteUser() in http://www.anujgakhar.com/2012/02/20/using-rest-services-in-coldfusion-10/ as an example of how to support DELETE in REST API style.
remote any function deleteUser(numeric userid restargsource="Path") httpmethod="DELETE" restpath="{userid}"
{
var response = "";
var qry = new Query();
var userQry = "";
qry.setSQl("delete from tbluser where id = :userid");
qry.addParam(name="userid", value="#arguments.userid#", cfsqltype="cf_sql_numeric");
userQry = qry.execute().getPrefix();
if(userQry.recordcount)
{
response = "User Deleted";
} else {
throw(type="Restsample.UserNotFoundError", errorCode='404', detail='User not found');
}
return response;
}
As for the 2nd part of your question, it'd be best to first turn a query into a array of structs first unless you're using CF11 which does it for you. See: http://www.raymondcamden.com/index.cfm/2014/5/8/ColdFusion-11s-new-Struct-format-for-JSON-and-how-to-use-it-in-ColdFusion-10
The default JSON structure for query in CF 8 to 10 were designed for <cfgrid> in ColdFusion on top of Adobe's discontinued Spry framework.
I've setup a form using googledocs. I just want to have the actual data entered into the form emailed to me, as opposed to the generic response advising that the form has been completed.
I have no skill or experience with code etc, but was sure i could get this sorted. I've spent hours+hours and haven't had any luck.
My form is really basic.it has 5 fields. 4 of which are just text responses, and one multiple choice.
I found this tute online (http://www.labnol.org/internet/google-docs-email-form/20884/) which i think sums up what i'm trying to do, but have not been able to get it to work.
from this site i entered the following code:
function sendFormByEmail(e)
{
var email = "reports.mckeir#gmail.com";
var subject = "Google Docs Form Submitted";
var s = SpreadsheetApp.getActiveSheet();
var headers = s.getRange(1,1,1,s.getLastColumn()).getValues()[0];
var message = "";
for(var i in headers)
message += headers[i] + ' = '+ e.namedValues[headers[i]].toString() + "\n\n";
MailApp.sendEmail(email, subject, message);
}
To this, i get the following response: ->
Your script, Contact Us Form Mailer, has recently failed to finish successfully. A summary of the failure(s) is shown below. To configure the triggers for this script, or change your setting for receiving future failure notifications, click here.
The script is used by the document 100% Club.
Details:
Start Function Error Message Trigger End
12/3/12 11:06 PM sendFormByEmail TypeError: Cannot call method "toString" of undefined. (line 12) formSubmit 12/3/12 11:06 PM
Is anyone able to help shed some light on this for me? I'm guessing i'm not including some data neeeded, but i honestly have no clue.
Workaround http://www.labnol.org/internet/google-docs-email-form/20884/
You have to setup app script to forward the data as email.
I'll point to the comment above that solved it for me: https://stackoverflow.com/a/14576983/134335
I took that post a step further:
I removed the normal notification. The app script makes that generic text redundant and useless now
I modified the script to actually parse the results and build the response accordingly.
function sendFormByEmail(e)
{
var toEmail = "changeme";
var name = "";
var email = "";
// Optional but change the following variable
// to have a custom subject for Google Docs emails
var subject = "Google Docs Form Submitted";
var message = "";
// The variable e holds all the form values in an array.
// Loop through the array and append values to the body.
var s = SpreadsheetApp.getActiveSheet();
var headers = s.getRange(1,1,1,s.getLastColumn()).getValues()[0];
// Credit to Henrique Abreu for fixing the sort order
for(var i in headers) {
if (headers[i] = "Name") {
name = e.namedValues[headers[i]].toString();
}
if (headers[i] = "Email") {
email = e.namedValues[headers[i]].toString();
}
if (headers[i] = "Subject") {
subject = e.namedValues[headers[i]].toString();
}
if (headers[i] = "Message") {
message = e.namedValues[headers[i]].toString();
}
}
// See https://developers.google.com/apps-script/reference/mail/mail-app#sendEmail(String,String,String,Object)
var mailOptions = {
name: name,
replyTo: email,
};
// This is the MailApp service of Google Apps Script
// that sends the email. You can also use GmailApp here.
MailApp.sendEmail(toEmail, subject, message, mailOptions);

}
The script utilized in the example is extremely generic but very resilient to change because the message is built as a key/value pair of the form fields submitted.
If you use my script you'll have to tweak the for loop if statements to match your fields verbatim. You'll also want to edit the toEmail variable.
Thanks again for the question and answers. I was about to ditch Google Forms as the generic response was never enough for what I was trying to do.
Lastly, in response to the actual problem above "toString of undefined" specifically means one of the form fields was submitted as blank. If I had to guess, I would say the author only used this for forms where all the fields were required or a quick undefined check would've been put in place.
Something like the following would work:
for(var i in headers) {
var formValue = e.namedValues[headers[i]];
var formValueText = "";
if (typeof(formValue) != "undefined") {
formValueText = formValue.toString();
}
message += headers[i] + ' = '+ formvalueText + "\n\n";
}
I haven't tested this precisely but it's a pretty standard way of making sure the object is defined before trying methods like toString() that clearly won't work.
This would also explain Jon Fila's answer. The script blindly assumes all of the header rows in the response are sent by the form. If any of the fields aren't required or the spreadsheet has fields that are no longer in the form, you'll get a lot of undefined objects.
The script could've been coded better but I won't fault the author as it was clearly meant to be a proof of concept only. The fact that they mention the replyTo correction but don't give any examples on implementing it made it perfectly clear.
If this is a Google Form, do you have any extra columns in your spreadsheet that are not on the form? If you delete those extra columns then it started working for me.
You don't need to use a script. Simply go to Tools >> Notification Rules on your Google Spreadsheet. There you can change the settings to receive an email with your desired information every time the document is changed.
Using titanium, does anybody have some simple instructions to get the user's facebook name, once signed into facebook?
you don't need to do any of this, the username is provided in the data response after the login is done.
Look at the appcelerator documentation
I haven't tested the code but you can try this:
var fbuid = Titanium.Facebook.uid; //this would be the logged user's facebook uid
function fQuery() //this function exec the fql query
{
var myQuery = "SELECT name FROM user WHERE uid = "+fbuid;
var data = [];
Titanium.Facebook.request('fql.query', {query: myQuery}, function(x)
{
var results = JSON.parse(x.result);
var username = results[0].name; //user's fb name
});
};
Ah, here is how you do it:
function getFacebookInfo(){
Titanium.Facebook.requestWithGraphPath('me', {}, 'GET', function(e){
if (e.success){
var jsonObject = JSON.parse(e.result);
//do something here with these values. They cannot be passed out of this
//function call... this is an asynchronous call
//that is, do this:
saveToDb(jsonObject.first_name);
} else {
//some sort of error message here i guess
}
});
};
Finally, along with name and username, check out the facebook page for the other variables you can get -
http://developers.facebook.com/docs/reference/api/
FINALLY: be aware that this is a callback, and titanium won't actually wait for this call to finish. That is, any variable declared to hold the results the returned after the requestWithGraphPAth will immediately return, and as a result almost always be empty.
I guess you could make a nifty loop that just... loops until some variable is set to false. And you'd set the variable to false in the callback... but that seems dodgy.
Just make your call back do everything else, that is, save to the db etc etc
If you do go the route of calling Ti.Facebook.authorise() to log in the user, remember to define
Ti.Facebook.addEventListener('login',function(e){
if (e.success){
...
...
} else if (e.error){ } else if (e.cancel) { }
}
before the call. And then, in the success bit, you can make a requestWithGraphPath call and so on. I just save all the details to the database and retrieve them each time after that, works fine for me!
