I am trying to merge two jsons into one but can't make it work. I manage to retrieve the data I need from both get, but I have troubles manipulating the jsons.
I planned on using two for loops but it doesn't work :
$scope.coursesJson = $http.get('https://api.myjson.com/bins/18zi3');
$scope.reviewsJson = $http.get('https://api.myjson.com/bins/52toz');
$q.all([$scope.coursesJson, $scope.reviewsJson]).then(function (values){
$scope.coursesJson = values[0];
$scope.reviewsJson = values[1];
for(i = 0;i<$scope.coursesJson.length;i++){
for(j = 0;j<$scope.reviewsJson.length;j++){
if($scope.coursesJson[i].name = $scope.reviewsJson[j].name){
$scope.coursesJson[i].reviews.push($scope.reviewsJson[j]);
}
}
}
console.log($scope.coursesJson);
});
Using the console, I can visualise the data but $scope.coursesJson.length is undefined and I don't understand why.
Maybe I don't understand $q well ?
EDIT :
Here is an example of the elements you could find in the coursesJson file I get() :
[{"code":"123 ","name":"Acteurs","courseContentGrade":null,"courseTeachingGrade":null,"courseAverage":null,"reviews":null},
{"code":"1234","name":"Advanced Excel","courseContentGrade":null,"courseTeachingGrade":null,"courseAverage":null,"reviews":null}]
And an example of the elements you could find in the reviewsJson file I get() :
[{"code":"123 ","name":"Acteurs","professor":"Lalala","contentReview":"C'est très réussi.","teachingReview":"charismatique","contentGrade":8,"teachingGrade":8,"average":8,"trimester":"T2","day":"Jeudi / Thursday","time":"9h-12h","round":"1er tour","bet":21,"year":"2014/2015","upvotes":"0","author":"Piranha","passed":null},
{"code":"123 ","name":"Acteurs","professor":"LAlalalala","contentReview":"Très intéressant !","teachingReview":"Disponible, claire.","contentGrade":8,"teachingGrade":8,"average":8,"trimester":"T2","day":"Jeudi / Thursday","time":"9h-12h","round":"1er tour","bet":25,"year":"2014/2015","upvotes":"0","author":"Piranha","passed":null}]
I would like to add the elements found in the reviewsJson to the reviews field of the elements of coursesJson. Could that be the problem ? I thought that using the push() method would create the array, but maybe I need to change all "reviews":null to "reviews":[] in coursesJson ?
I went to the url https://api.myjson.com/bins/ID1 and it's not an array, but an object. Instead of $scope.coursesJson.length I think you shouldbe doing $scope.coursesJson.tracks.length
I solved my issue really easyly and my question was actually pretty stupid.
What I tried to achieve didn't have its place on the front but on the backend.

I extracted from a previous response an Object of tuple with the following regex :
.check(regex(""""idSc":(.{1,8}),"pasTemps":."codePasTemps":(.),"""").ofType[(String,String)].findAll.saveAs ("OBJECTS1"))
So I get my object :
OBJECTS1 -> List((1657751,2), (1658105,2), (4557378,2), (1657750,1), (916,1), (917,2), (1658068,1), (1658069,2), (4557379,2), (1658082,1), (4557367,1), (4557368,1), (1660865,2), (1660866,2), (1658122,1), (921,1), (922,2), (923,2), (1660875,1), (1660876,2), (1660877,2), (1658300,1), (1658301,1), (1658302,1), (1658309,1), (1658310,1), (2996562,1), (4638455,1))
After that I did a Foreach and need to extract every couple to add them in next requests So we tried :
.foreach("${OBJECTS1}", "couple") {
exec(http("request_foreach47"
.get("/ctr/web/api/seriegraph/bydates/${couple(0)}/${couple(1)}/1552863600000/1554191743799")
.headers(headers_27))
}
But I get the message : named 'couple' does not support index access
I also though that to use 2 regex on the couple to extract both part could work but I haven't found any way to use a regex on a session variable. (Even if its not needed for this case but possible im really interessed to learn how as it could be usefull)
If would be really thankfull if you could provided me help. (Im using Gatling 2 but can,'t use a more recent version as its for work and others scripts have been develloped with Gatling2)
each "couple" is a scala tuple which can't be indexed into like a collection. Fortunately the gatling EL has a function that handles tuples.
so instead of
.get("/ctr/web/api/seriegraph/bydates/${couple(0)}/${couple(1)}/1552863600000/1554191743799")
you can use
.get("/ctr/web/api/seriegraph/bydates/${couple._1}/${couple._2}/1552863600000/1554191743799")
In reactjs I want to display a property.
Normally this isn't really hard to do it, but this time there is a number in the property. And that number depends on how many links the user has added.
This is an example of what my api returns to my react app:
embed_links: ["2"]
embed_links_0_embed_link: ["https://www.url.com"]
embed_links_1_embed_link: ["https://www.url.com"]
The embed_links is an array which says how many urls the user has filled in.
Then you get the urls the user has filled in, and each one has a number in it.
This is where I got stuck. I have tried to display the links with a for loop like this:
let embed_links = this.props.embed_links[0]
for (let i = 0; i < embed_links; i++) {
console.log(this.props.embed_links_[i]_embed_link[0]);
}
But this does not work..
So my question is basically, is there a possibility that you can display properties witch custom variables/numbers in it?
If you are asking access to a dynamical property within your object:
console.log(this.props["embed_links_" + i + "_embed_link"][0]);
Your syntax is wrong, the correct way to write this is as follows:
let embed_links = this.props.embed_links[0]
for (let i = 0; i < embed_links; i++) {
console.log(this.props['embed_links_' + i + '_embed_link][0]);
}
In the example, 'embed_links_' + i + '_embed_link' is the key that you use to select the correct property of object props.
Yes you can use this.props['embed_links_' + i + '_embed_link'][0]
However i would suggest storing your embed links in an array as objects
embed_links_collection: [
{
url:'https://www.url.com',
id: '1'
}
]
This is a cleaner, managable solution - you could also generate your embed_links property as this.props.embed_links_collection.length
You can use for .. in for enumerating this.props properties
http://example.com/api/transfer/transfers/code/456/code/234
When using $this->get('code') on a url like above I expect the REST library to return an array or a list of the codes.
Instead it returns the last one.
Is there a way to return both values in a list, or is there another recommandation for formating the URL.
Thank you
I know it has been long since you posted the question. However it could help other people looking for the same thing.
Assuming that transfer is your controller and transfers is the function, another way to format your url could be:
http://example.com/api/transfer/transfers?code[]=456&code[]=234
This was you perform $this->get('code') you'll get an array back.
If you are creating the url via code then you may use http_build_query(). It handles the necessary escaping. It means it will replace [ for %5B and ] for %5D, in this case.
The code would be like:
$codes = array(456, 234);
$query = http_build_query(array('code' => $data));
$url = 'http://example.com/api/transfer/transfers?' . $query;
If I have an array of photos in coffeescript
photos = [ly.p1, ly.p2, ly.p3, ly.p4, ly.p5, ly.p6, ly.p7, ly.p8, ly.p9, ly.p10, ly.p11, ly.p12]
for photo, i in photos
photoMask = new Layer
How can I write my for loop so that the resulting photoMask objects are outputted as photoMask1, photoMask2, photoMask3 .. photoMask12 ?
EDIT: Further elaboration
Maybe the best way to explain this is what I am trying to do in psuedocode:
for photo, i in photos
photoMask[i] = new Layer
photoMask[i].addSubLayer(photo)
So ly.p1 would have a corresponding photoMask1. That way, I can access photoMask1 separately and independently.
While I agree to the commenters about this being a bit strange, you could use something like this:
photos = [ly.p1, ly.p2, ly.p3, ly.p4, ly.p5, ly.p6, ly.p7, ly.p8, ly.p9, ly.p10, ly.p11, ly.p12]
masks = {}
for photo, i in photos
photoMask = new Layer
masks["photoMask#{i}"] = photoMask
This will create dynamic keynames within the masks object. If you really need them globally (in the browser) you could do the same thing with the window object.
But without knowing what exactly you're trying to do, I wouldn't recommend any of the above.
i have an array.
At some stage, i'm adding more data to it.
So we have:
$editable = someArrayGeneratingFunctionHere();
$points = preg_split('/,/',$this->data['Video']['points']);
lovely. Now, the "points" array has a bunch of data that may or may not already be in the editable array.
What i want is to check if the data is in editable, and add if not.
I'd like to do this efficiently too.
So, i have this method:
private function associateWithRelatedBodyParts($editable, $keysAlreadyPresent, ...){
$point = getOtherPointsThatAreRelatedToThisPoint();
if (!isset($keysAlreadyPresent[$point])){
insertDataIntoEditable();
} //else the value is already here. Do not add it again!
return $editable;
}
so the whole thing looks like this:
$editable = someArrayGeneratingFunctionHere();
$points = preg_split('/,/',$this->data['Video']['points']);
$valuesInEditable = ...
foreach ($points as $point){
$editable = $this->associateWithRelatedBodyParts($editable, $valuesInEditable,...);
}
What a lot of setup! The whole point of all this is thus:
i want to flatten the original $editable array, because that way, i can quickly test if a point is in the editable. If it is not, i'll add it.
My current way to retrive the valuesInEditable array is
$valuesInEditable = Set::combine($editable, 'BodyPartsVideo.{n}.body_part_id','BodyPartsVideo.{n}.body_part_id');
This is moronic. I'm sticking the same value twice into the array. What i'd really like is just:
$valuesInEditable = Set::combine($editable, 'BodyPartsVideo.{n}.body_part_id',True);
or something like that. So the whole point of this question is:
how do i set a default value using Set:combine in cakephp. If you have a better suggestion, i'd love to hear it.
Without seeing the structure of your array, it seems like you are going through a lot of work to combine the two arrays. Is there a reason you cannot use
$final_array = array_merge($points, $editable);
before running the set combine?
