In my request variable I have GET: <QueryDict: {'order_by': ['id'], 'del': ['11']}>
How can I remove the 'del':['11']?
I tried several things to delete the 'del'. I think the delattr is maybee the right way but e.g. with delattr(request.GET,'del') I got an error message.

I've been searching and searching, including the many topics here, for a solution to my problem. I've had no luck thus far.
A bit of a backstory: I'm writing an AngularJS app with Drupal 7 as a backend. I'm able to login without problem, save Session Name and Session ID, and put them together for a Cookie header (I had to use this "hack"). Further, if I made a login call in the Postman app, then tried to update the node, it'd work. It makes me think that there's a problem with session authentication, but I still can't figure it out.
That being said, I'm at a roadblock. Whenever I try to PUT to update a node, I get the following error:
401 (Unauthorized : CSRF validation failed)
Now, my ajax call looks like this:
$http({
method: 'PUT',
url: CONSTANTS.SITE_URL+"/update/node/"+target_nid,
headers:{
'Content-Type': CONSTANTS.CONTENT_TYPE,
'Authentication': CONSTANTS.SESS_NAME +"="+CONSTANTS.SESS_ID,
'X-CSRF-Token' : CONSTANTS.TOKEN
},
data: {
(JSON stuff)
}
})
The CONTENT_TYPE is "application/json", the "Authentication" is the band-aid for the Cookie header problem, and the "X-CSRF-Token" is what is (presumably) giving me the problem. SESS_NAME, SESS_ID, and TOKEN are all gathered from the response at Login. I can pull lists made by users on the website, I can pull the list of all of the nodes of a certain type on the website as well. I only run into a problem when I attempt to PUT to update the node.
If I missed any information, let me know and I'll add it!
EDIT: I'm using AngularJS version 1.5.3.
After trying everything else, I followed one of the comments in the thread I linked at the beginning of my original post. They had to comment out a line in Services.module :
if ($non_safe_method_called && !drupal_valid_token($csrf_token, 'services')) {
//return t('CSRF validation failed');
}
It's around line 590, plus or minus a few depending on how much you've messed with the file. I don't like doing it this way, but I can't for the life of me figure out why the token's not working right. It's a temporary fix, for sure, but if someone runs across this with the same problem in the future it'll hopefully help you out!
Instead of removing the line you could also add a true to drupal_valid_token
if ($non_safe_method_called && !drupal_valid_token($csrf_token, 'services',true)) {
return t('CSRF validation failed');
}
I'm building an SPA in AngularJS served by a Laravel (5.1) backend. Of late I've been encountering an annoying error, a server 500 or code 0 error which is abit hard to explain how it comes but let me try to may be someone will understand the dental formula of my problem.
When i start my AngularJS controller, I make several server calls (via independent $http calls from services) to retrieve information i might later need in the controller. For example,
Functions.getGrades()
.then(function(response)
{
$scope.grades = response.data;
});
Subjects.offered()
.then(function(response)
{
$scope.subjects = response.data;
});
Later on i pass these variables (grades or subjects) to a service where they are used for processing. However, these functions are randomly returning code 500 server errors after they run, and sometimes returning status code 0 after running. This happens in a random way and it is hard for me to point out the circumstances leading to their popping up. This leaves me with frequent empty Laravel-ised error screens like the ones shown below.
Anyone reading my mind?
Ok, after a suggestion given in a comment above that I check my Laravel log files (located in storage/logs/laravel.log- Laravel 5.1), i found out that the main error most of these times was this one: 'PDOException' with message 'SQLSTATE[HY000] [1044] Access denied for user ''#'localhost' to database 'forge'' in ..., plus another one that paraphrased something like No valid encrypter found. These were the key opener.
On reading another SO thread here, it said in part:
I solved, sometimes laravel not read APP_KEY in .ENV. And returns a value "SomeRandomString" (default is defined in config / app.php), and have the error "key length is invalid", so the solution is to copy the value of APP_KEY, to the value 'key 'in config / app.php, that's all! I solved!
That was exactly the issue! When loading the DB params from the .env to config/database.php, Laravel was sometimes unable to read the environment variables and went for the fallback default fallback options (forge for DB name and username and SomeRandomString for the APP_KEY). So, to solve this i just did as advised: copied the APP_KEY in .env to the config/app.php and edited the default DB parameters to the actual DB name and username/password I'm using. Just that and i was free from pollution. Hope someone finds this helpful.
I am pretty new to angularjs. Love it but sometimes get surprises that I just can't find an answer.
I have a function that lets the user build a list to a file by clicking a link. This can take up to a minute so the user can build different lists at the same time. The meaning is that once the file is build a popup appears to download it.
All of this works when only 1 file is build. After a half a minute the download popup shows up. But when 2 are build at the same time the second POST is cancelled (it arrives in the error callback) once the pop-up of the first appears.
If I remove $window.open both POST are finished succesfully and I get both fileId's in the console log.
Clearly the problem lies with $window.open. But why? What am I doing wrong or how can I solve this? Anyone an idea? I have been searching for hours already but can't seem to find anything on this case.
$scope.idPromise = $http.post(restPath, $scope.data)
.then(function(data){
console.log(data.data);
console.log(data.data.fileId);
$window.open(restPath + 'files/' + data.data.fileId, '_self');
},function(error){
console.log('promise error')
});
So when two lists are build without window.open in the code I get something like this in my console:
POST http://localhost:8080/xxx-rest/rest/lijsten/vastelijsten/gezinshoofdenMetLeden 200 OK 1m
POST http://localhost:8080/xxx-rest/rest/lijsten/vastelijsten/gezinshoofdenMetLeden 200 OK 1m 40s
report3545743463669473959.xlsx
report4733168386603499105.xlsx
when window.open is placed in the code:
POST
http://localhost:8080/xxx-rest/rest/lijsten/vastelijsten/gezinshoofdenMetLeden
200 OK 1m
POST
http://localhost:8080/xxx-rest/rest/lijsten/vastelijsten/gezinshoofdenMetLeden
x 56,39s

promise error
As you can see the last POST is stopped as soon as the first POST gets a response, so for the second POST no response is gotten.
Update
It seems the problem lies with the grunt server and the liveReload Protocol. My college had always told me to ignore this error but it is now clear that because the page loses connection that the promise fails.
Does anyone have experience with grunt and liveReload? Can I fix this? Will it work on a production server?
The console error I get:
De verbinding met ws://localhost:35729/livereload werd onderbroken
tijdens het laden van de pagina. this.socket = new
this.WebSocket(this._uri);
(translated: the connection with... was interrupted)
I have configured the path in the module:
function mymodule_restws_resource_info() {
return array(
'mymodule_person' => array(
'label' => t('Person'),
'class' => 'PersonResourceController',
'menu_path' => 'api/person',
),
);
}
That part seems to work, because when I send a POST transaction via Advanced Rest Client in chrome, I get a 200 response (I get a 404 if I change the request url).
That said, in the module I also throw an error if attempting an update, delete or read. When I send any of those, I still get a 200 response.
Any of GET, POST, PUT or UPDATE gives me
Response does not contain any data
including the create method in the resource controller, so it's not firing.
Do I need to do something to invoke it beyond hitting the url with a post payload?
The problem seems to revolve around the workflow_moderation module being in the mix. If I enable restws and attempt just to hit node/1.json, I get a white screen and an error in the logs. It seems to be a known issue at this point that workflow_moderation is not including the correct parms when it passes the node on. https://drupal.org/node/1238040
When using a Restful Store the remove command is throwing an error (Line 1717 of ext-base-debug Error: Invalid argument) when it tries make the DELETE ajax request. Specifically the error is occurring in the asyncRequest method in ext-base when o.conn.send(postData || null); is called. I created a standard Ajax request and used the DELETE method along with the same URL and it worked fine. All other actions in the Store (Create, Read, and Update) work fine.
The EXT JS example RESTful store throws an error as well located here: http://www.sencha.com/deploy/dev/examples/restful/restful.html
It looks like :
Problem with jQuery.ajax with 'delete' method in ie
I tracked down the problem which stemmed from using the ext-basex user extension. If you are using ext-basex try overriding the forceActiveX boolean by adding this to your overrides: Ext.lib.Ajax.forceActiveX = true;
