So, I spent some time and built a quick API for a project that I'm doing for myself.
I used the Postman add-on for Chrome to mimic PUT and DELETE quests to make sure everything worked correctly. Really happy I did that, as I learned a lot about PHP's shortcomings with PUT and DELETE requests.
Using the API I've had working with Postman, I started moving everything over to AngularJs controllers and such.
I'm trying to get a user to claim a row in a database as the login information for the users is different than this particular information. I couldn't figure out why the put requests to claim the row in my database wasn't working. Lo and behold, the data being parsed from my parsestr(file_get_contents('php://input')) had 1 array key, which was a JSON string.
I've looked, and I can't seem to find a solid answer either through Stackoverflow or Google (maybe I missed it somewhere in the config options), So my question is this: is there any way I can get the $http.put call send the data to the server correctly?
Thanks to user Chandermani for pointing me to the link at this URL which answered the base of my question.
From the above link, I found myself on This Blog post submitted by another user. In the end, what I ended up doing was the following:
taking param() function from the above link, as well as implementing these lines of code:
var app = angular.module('ucpData', [] , function($httpProvider){
$httpProvider.defaults.transformRequest = [function(data) {
return angular.isObject(data) && String(data) !== '[object File]' ? param(data) : data;
}];
});
Is how I worked around the problem. For some developers, you may actually want to keep the default transformRequest settings, but for the project I am doing I know that I will end up forgetting to call param() at some point, and my server doesn't naturally accept json data anyway. I would caution future developers to consider what they are attempting to do before they alter the transformRequest array directly.

I'm trying to use a REST web service from Geonames.org. When I try to manually put in the url with the parameters, it would only return the Country Code. I've tried to search for ways to implement it, but most of what I've seen return JSON text with multiple keys and data. I feel like the answer should be pretty simple, but I'm unsure.
I'm trying to use this for a React project I'm working on.
Here is an example of what the url returns
Just looked into the docs of that API, and it says if you want to receive JSON responses simply add JSON keyword to the endpoint. Like here for given endpoint you have:
http://api.geonames.org/countryCodeJSON?formatted=true&lat=47.03&lng=10.2&username=demo
so just change countryCode to countryCodeJSON.

I am trying to use the API to return data from the Chagrin Falls station in Ohio. I can get the data from the website so I know there is data, but the API does not return any values.
I have a valid token and the examples in the documentation work, but if I try any to alter the examples in any way I get nothing back just any empty json object {}.
Example I am trying to use:
https://www.ncdc.noaa.gov/cdo-web/api/v2/data?datasetid=GSOM&stationid=GHCND:US1OHGG0014&units=standard&startdate=2020-08-01&enddate=2020-08-01&limit=1000
Data from the website:
https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:US1OHGG0014/detail
I don't exactly know how you are going to achieve this since you haven't told us what programming language you are using. However, with python I use a module called urllib to extract raw html data from a url that can be seen from the browser using ctrl+u.
I recently went through the www.clementinejs.com tutorial as I'm trying to learn the MEAN stack. I was able to complete it and understand most of it. However when i'm trying to repeat the process with mongoose and get slightly more data, I keep failing.
What i'm trying to do:
When page loads angular performs get request to '/api/entries' which searches mongo(via mongoose) and returns all docs in the collection, then load those docs into a div via angular ng-repeat.
If I insert dumby data into an object in the controller file I have no problem getting the data to show on the page, but when I try with the database I messed up somewhere. Even the angular curly brackets show up when I try to do it that way.
Here is my repo.
https://github.com/nickolaskg/journal
Should I just use mongo instead of mongoose? I'm not sure if i've set it up correctly.
Any help is greatly appreciated. I've been stuck for days trying so many different approaches, at this point I have no doubt there is multiple problems in the code.
Entry.get(function(result){
$scope.entries = result;
})
get() expects single object in the response.
Please read $resource's docs
Use:
Entry.query({field1: 'criterion'}) for queries and multiple resources.
Entry.get({_id: 'someid'}) for a single resource.
Entry.save({my: 'properties'}) for saving existing resource or creating a new resource.
Entry.delete({_id: 'someid'}) for deleting a single resource.
Also next time please post relevant code (IE your $resource calls) directly.
I am working on a project based on CKAN, and I am required to list in a page all the datasets that have the state "active" and "draft". When you go to the datasets page, you can only see the ones that have the state marked as "active", but not "draft".
If I use the API (call the package_list() method) or REST calls (http://localhost/api/3/action/package_list), CKAN only returns "active" datasets, but not "drafts". I double and triple checked the documentation, and apparently one cannot lists the datasets by their state.
Does anybody have a clue on how to do this? Has anybody done this already?
Thanks!
If nothing else, you could write an extension to do this. The database call itself will be pretty simple:
SELECT id,title,name FROM package WHERE state='active' OR state='draft';
I managed to modify CKAN core to list the datasets that do not have the state "draft" or "deleted", and it works, but I do no want to touch CKAN's core, I want to do this using a plugin, so the normal thing to do is to implement plugins.IActions and override the package_list method with a custom one. I have already written my own extension to try to modify CKAN behavior on method package_list(), but I can't seem to figure it out how to make it work.
Here is my code:
#side_effect_free
def package_list_custom(context, data_dict=None):
datasets = []
dataset_q = (model.Session.query(model.Package)
.join(model.PackageRole))
for dataset in dataset_q:
if dataset.state != 'draft' and dataset.state != 'deleted':
datasets.append(dataset)
return [dataset.id for dataset in datasets]
class Cnaf_WorkflowPlugin(plugins.SingletonPlugin):
plugins.implements(plugins.IActions)
def get_actions(self):
return {
'package_list' : package_list_custom
}
If I modify CKAN core it works very well, but the problem is that I am not to touch it, so I am obliged to do it via an extension.
EDIT: Ok, I managed to make it work, you need to decorate the method with #side_effect_free. I modified my code, and now it works.
The package_search API is capable of this, by searching for state:draft and setting the include_drafts=True flag. Something like this:
https://my-site.com/api/action/package_search?q=state:draft&include_drafts=True
You should be able to access this from a plugin with something like: ckan.plugins.toolkit.get_action('package_search')(context=context, data_dict={'q': 'state:draft', 'include_drafts': True}) (you'll need to assemble the context yourself, containing a 'user' key for the current username and a 'userobj' key for the current user object).
Then make a page from the results.
I'm writing a url shortener, I already solve url shortening. Given a certain long URL (LURL), I get a CODE with the help of a script and a database to form a short URL (SURL) of the type:
mysite.com/CODE
So the ralationship between the code and the LURL is stored and must be consulted in the DB. Now as you can see I need a way to do that. My plan is that all the all url in mysite.com direct to the same page where the CODE is taken as a parameter and in this way make a consult in the db fetching the code from the SURL and then redirect with a script to the LURL.
I dont want to generate a SURL that uses a GET request like:
mysite.com/?CODE
It would be easier but I decided not to do it because it defeats the propose of url shorteners by occupying a character unnecessarily.
How would you implement it? Is this method convenient? If you do not think so I would really appreciate you give me your opinion. Maybe there are better ways to do it now that I already have the DB and the shortening algorithm. See you later.
http://www.webcheatsheet.com/PHP/get_current_page_url.php
check out the curPageURL() function.
$pageURL = curPageURL();
$itemArray= explode("/", $pageURL);
$myCode = $itemArray[1];
something like that will do, but not tested. It just gives you an idea of what you can do.
also, to get the url, here is an simplified version: http://phpeasystep.com/phptu/27.html
