I'm trying to use the Spotify objective-c library to search for a specific song that belongs to an artist, album. I don't want to use the searchWithSearchQuery method (which works ok) because I want to be more specific. There is a method called searchWithURL shown below. I don't see any documentation as to how to structure these URLs. All it says is that it must start with spotify:search. What comes after that? How do I specify a artist, album, song? Thanks!
/** Creates a new SPSearch with the default page size from the given Spotify search URL.
This convenience method is simply returns a new, autoreleased SPSearch
object. No caching is performed.
#warning If you pass in an invalid search URL (i.e., any URL not
starting `spotify:search:`, this method will return `nil`.
#warning The search query will be sent to the Spotify search service
immediately. Be sure you want to perform the search before creating the object!
#param searchURL The search URL to create an SPSearch for.
#param aSession The SPSession the track should exist in.
#return Returns the created SPSearch object.
*/
+(SPSearch *)searchWithURL:(NSURL *)searchURL inSession:(SPSession *)aSession;
Search URLs are created by SPSearch instances after you create them, and they basically encode the query you passed the first time. So, searchWithURL: isn't going to be more useful to you than creating a search with a query.
However, to answer your wider question, you can use the Spotify Advanced Search Syntax with SPSearch to do a more accurate search.
For example, to find tracks exactly named "Roar":
[SPSearch searchWithSearchQuery:#"track:Roar"
inSession:[SPSession sharedSession]];
To find tracks exactly named "Roar" by Katy Perry:
[SPSearch searchWithSearchQuery:#"track:Roar artist:\"Katy Perry\""
inSession:[SPSession sharedSession]];
...and so on. Check out the linked page for more details.

I am trying to add a new custom enrolment method to a base Totara (Moodle) installation. I decided to copy the existing "Self enrolment" enrolment method, because it is relatively simple and therefore seemed to be a good starting point for my custom method.
I changed the name and all of the references to the "Self enrolment" method to my new method name. This seemed to have worked because when I logged into the Totara dashboard I got the popup for a new plugin installation.
I went through the installation process and didn't run into any errors. Next I activated my plugin in the "Enrolment plugin" menu. Everything seemed fine until I tried to add my new method to a course.
Firstly the new method should be displayed bij default on the "Enrolment methods" page of the course but it isn't, however I can select it with the dropdown located below. When I do I am redirected to the config page of the enrolment method, so far so good. But when I click the button on the bottom of the page to add the method to the course it still isn't visible on the "Enrolment methods" page of the course.
When I log in as a regular user I can't access the course through my new method, so the method and the course haven't been properly linked. However when I look in the database I do see that my new method has been added to the course in the enrol table.
The problem doesn't seem to be caching related because I have purged it a couple of times already but the method still won't show up.
I am working with Totara version 16.2 (Moodle 3.4.9)
I found the problem, it seems that the "Self enrolment" plugin uses the get_name() function of the /server/lib/enrollib.php by default. However this function is written in a way to avoid "fancy" plugin names according to a comment in the function. The function explodes your plugin name on "_" and only uses the first part of your name, which means the records in enrol won't be recognised as records of your plugin because the names don't match.
I solved this by adding my own get_name() to my plugin, which returns the whole name.
The function:
/**
* Returns name of this enrol plugin
* #return string
*/
public function get_name() {
// second word in class is always enrol name, sorry, no fancy plugin names with _
$words = explode('_', get_class($this));
return $words[1];
}
I am working on an AR app in Unity and want to display information of an object. To display said information, the user has to be able to click/select that object.
I cannot find the line of code that creates the objects.
I have tried to use a snippet of the ARTabletopKit that handles the user's input to select an object.
If I am correct, the problem is that I cannot use the DebugCanvas-GameObject of the WorldScaleAR example as it does not contain any of the actual game objects.
As far as I can see the objects are created and placed here:
unityTile.Initialize(_map, tileId, _map.WorldRelativeScale, _map.AbsoluteZoom, _map.LoadingTexture);
PlaceTile(tileId, unityTile, _map);
At last I expect the method EventSystem.current.IsPointerOverGameObject() to return true.
Cheers!
You'll need to add a [GameObjectModifier][1] to handle the onClick. You can configure the modifiers to be added at runtime on the game objects in the Map Features area of the AbstractMap.cs script.
I would take a look at how it's implemented on the Data Explorer example.
I'm trying to crawl a site and to do so, I'm using Scrapy. So, when doing requests to nested pages, the procedure usually gets the the information correctly on the first trials, but, on later requests the nodes starts to return None. I'm using xpath's functionality. Below I'm pasting some lines of the parse function:
(I tried this one with the approach of explicitly comparing the class value)
title = response.xpath('//span[#class="inlineFree"]/text()').extract_first()
(With this one I used the contains function)
view = response.xpath('//span[contains(#class,"count")]/text()').extract_first()
(I've also used this one when I found more suitable)
comments = response.css('div.commentMessage > span::text').extract()
Am I doing something wrong on paths?
Is there any reason for the crawler to stop reading the nodes correctly?
Cannot say what the problem is without the log messages or the spider code but..
What happens most of the time is that websites fo not follow a strict html structure .For some properties the 'title' may be inside the span
but for the next iteration it may be
span[#class="inlineFree"]/h1/text() or or any other tag
so you should check the html for those returning None
I've got a GitHub repo/branch where I'm attempting to update the README.rst, but it's not formatting the way I expect when it comes to the bullet lists I'm including.
Everything seems ok except for my Usage section, in which I have the following:
*****
Usage
*****
- Open the template file that corresponds to the API call you'd like to make.
* Example: If we want to make a call to the RefundTransaction API we open up /templates/RefundTransaction.php
- You may leave the file here, or save this file to the location on your web server where you'd like this call to be made.
* I like to save the files to a separate location and keep the ones included with the library as empty templates.
* Note that you can also copy/paste the template code into your own file(s).
- Each template file includes PHP arrays for every parameter available to that particular API. Simply fill in the array parameters with your own dynamic (or static) data. This data may come from:
* Session Variables
* General Variables
* Database Recordsets
* Static Values
* Etc.
- When you run the file you will get a $PayPalResult array that consists of all the response parameters from PayPal, original request parameters sent to PayPal, and raw request/response info for troubleshooting.
* You may refer to the `PayPal API Reference Guide <https://developer.paypal.com/webapps/developer/docs/classic/api/>`_ for details about what response parameters you can expect to get back from any successful API request.
+ Example: When working with RefundTransaction, I can see that PayPal will return a REFUNDTRANSACTIONID, FEEREFUNDAMT, etc. As such, I know that those values will be included in $PayPalResult['REFUNDTRANSACTIONID'] and $PayPalResult['FEEREFUNDAMT'] respectively.
- If errors occur they will be available in $PayPalResult['ERRORS']
You may refer to this `overview video <http://www.angelleye.com/overview-of-php-class-library-for-paypal/>`_ of how to use the library,
and there are also samples provided in the /samples directory as well as blank templates ready to use under /templates.
You may `contact me directly <http://www.angelleye.com/contact-us/>`_ if you need additional help getting started. I offer 30 min of free training for using this library,
which is generally plenty to get you up-and-running.
For some reason, though, when you look at that on GitHub the first line of the bullet lists is coming up bold and italics and I have no idea why. Also, the sub-list where it shows Session Variables, General Variables, etc. is supposed to be all the same sub-list. I'm not sure why it's dropping into another sub when it sees General Variables.
Any information on what I've done wrong here would be greatly appreciated. Thanks!
Switch from .rst to .md and then use '#' for your headings.

I have tried my best to search for an existing question with smiliar issue but was not able to find one. Here's my situation
I have a controller named search which accepts a parameter "search term", when this controller is called directly from URL like www.xyz.com/search/red+car it returns results and the URL in browser address bar is www.xyz.com/search/red+car but when the user submits the search from a from in webpage with same term, the results are coming fine but the URL does not reflect the search term.
If I do a redirect the form POST data is lost, although resubmitting the POSt is not a solution in my case either. I need a way to change the URL so that it shows the search term.
Thanks in advance for your help, please be gentle as this is my first question.
#Vlakarados - I am trying to use same controller to provide search results from post data and controller parameter. Both work fine but when using search form on webpage the search parameter is not reflected in URL.
#Rakesh Shetty - The actual method is very long, but here is the compressed format
build query as per post data and passed parameter.
populate view with results
render the view
Thanks everyone for suggesting various solution.
I used jquery to change the form action parameter, now when ever the dropdown selection is changed the value is appended to the action parameter. I also took out the dropdown from being part of post data.
There are 2 dropdowns one for area and other for zip code. This new approach works with bot dropdowns and my exsting code of controller works without any major change.
I used the following javascript code to create new action parameter when ever user changes the area. Same goes for ZIP code.
$("#cityname").change(function(){
var action = $(this).val();
alert(action);
$("#searchform").attr("action", "search/" + action);
});
I think I was not able to clearly explain my situation otherwise you people would have suggested this long ago.
The better way to do it is in your controller:
function search($search_query) {
// .. use your query as you normally would - display products, posts, messages
$data = array('search_query' => $search_query);
$this->load->view('search', $data);
}
// use this method as the form action
function search_proxy() {
$search_query = $this->input->post('search');
// if needed urlencode or other search query manipulation
redirect('controller/search/'.$search_query);
}
This way you will have no problems and will only work with data in your url.
Edit: The second option is yo use JavaScript - when user submit's the form, change the form's action to include the searched query in form action
