I am trying to use plupload-angular-directive in my Angular SPA. The problem is, the upload URL is not a constant and is generated on the server side every time I need to upload something.
So, as mentioned in the docs I have used the pl-url directive to set the URL on the front-end like this:
<button pl-upload=""
pl-auto-upload="true"
pl-files-model="multiFiles"
pl-url="{{imgActionUrl}}"
pl-progress-model="percent">Upload Images</button>
where, the imgActionUrl is fetched by my Angular controller and assigned to the $scope.
Debugging the application clearly showed that the URL is being properly set but even then, when the upload actually happens, it makes a POST to /upload.php rather than to the address mentioned in the directive.
Why is this happening?
After a lot of digging around, I posted an issue on the github page of the project:
https://github.com/sahusoftcom/plupload-angular-directive/issues/43
But it seems nobody is maintaining this repository and the owner redirected me to another library, jQuery-File-Upload.

The problem:
I have a express backend/angularjs frontend web app hosting all of my teams documentation for our users. We frequently need to post links to a specific question (all linked as ids) to our users in Slack. ex. helpapp.com/productTheyNeedHelpWith#QuestionLinkedTo the problem is that when the link is clicked from slack, not when copy/pasted, Slack launches a new browser window/tab to helpapp.com/productTheyNeedHelpWith%23QuestionLinkedTo.
This breaks ngRoute as it no longer recognizes /productTheyNeedHelpWith as the path to load the correct page for and the user gets sent to our home page instead.
Thoughts on possible solutions:
I'd like to solve this issue either in the ngRouting itself by somehow updating the path by replacing %23 with # before $routeProvider does it's magic, or by somehow capturing the full url in app.js and updating it or redirect to an updated version before we've rendered a page view at all.
currently I've set a workaround by using a ng-init event to check the url and, if %23 is found, update it and replace it with the correct extension but this causes an odd double load that leads to a poor user experience.
Final Thoughts:
As I'm not sure of the best way to go about this, and because our code is proprietary, I'm avoiding posting to much 'example code' that may not be relevant but am happy to provide any parts of it that you, wonderful stackoverflowers, may request. Thank you in advance for your assistance.
I am working on a project that uses Angular1, we hit the problem where when we change an html template the users will not see the change until a hard refresh is performed. Ideal would be to have the cache service to check a timestamp and invalidate the cached file. As an example now I edited a template used by the $stateProvider.
My questions is what solutions or best practices are used to solve the problem?
P.S since our JS files are combined in 1 file we fixed the problem there by appending a timestamp in the script tag from our PHP backend
Interesting question! We've had the same issue in a project that uses Angular1.x. We solved it using angular-cache-buster.
It basically helps you put a httpInterceptor. All you need is have ngCacheBuster in module dependency injection, and inject httpRequestInterceptorCacheBusterProvider in the .config of your app to set the match list.
For example,
httpRequestInterceptorCacheBusterProvider.setMatchlist([/.*api.*/], true);
this tells it to cache everything except REST api requests. You can learn more about the configuration here.
I am currently working on a project using Django and Angular. I am trying to implement Django's Password-Reset app, which seems pretty easy to set up. I followed the instructions and I ran into a peculiar issue that is caused by Angular's routing. I am trying to link to a FormView using
Forgot password?
But it seems that Angular's routing keeps picking up the literal translation of the link
http://127.0.0.1:8000/%7B%%20url%20'password_reset_recover'%20%%7D
This of course causes a routing error to pop up.
Is there anyway I can link to this view without Angular interfering?
Looks like the problem is that Django is not parsing your URL tag in the template. Might want to look into that rather than into Angular
Could you check the a tag in your Developer tools and see what it says? Chances are that it says exactly what the URL is pointing to.i.e. /%7B%%20url%20'password_reset_recover'%20%%7D
Have you added password_reset_recover in your root urls.py?
When developing a web application with angular js, a part of time that developers spend is the time for implementing routing.
When using ui-router in a application, there are two "phases" to consider with regards to routing:
user navigates inside application: when click is made on some button, user is transfered to another state by using $state.go("somestate"). Parameters can be send etc. And url is changed accordingly.
user navigates directly via url.
Lets say application has such route:
/mythings/{thingid}/mysubthings/{mysubthingid}
If user navigates to that url directly by pasting it into browser window, application needs to handle it. My question is what's the best practice to do it?
What I'm thinging is: if looking at url example above what needs to be done when user enters that url in browser:
get {thingid} from url (from $stateParams), then get {mysubthingid} also from $stateParams (probably by using resolve (ui-router feature) when defining state), then inject what was resolved to controller and then make a query to api and get data about "subthing" and present view in ui with that data. So that should work with both "types of navigations": when user clicks and is transfered to state, or when user enter url directly into browser. Is this the right path to go?
And I suppose that any url you go to when you click something in application, you should be able to take that url and just paste it into browser and see the same results without being redirected to anywhere else. If application cannot handle every url in such way, maybe application' architecture needs to be reconsidered?
Thanks
In UI-Router, the main component of the routing is the state. The URL is essentially just an address that points to a specific state of the app. I don't think it's necessarily productive to think of the two ways of navigating as separate; they're just two sides of the same coin. There should be no URL that isn't handled by a state. Any URL that doesn't match a state should be caught by the otherwise definition on the $stateProvider and probably redirect to your home page or a 404 page.
In your example, the thing/:thingId/subthing/:subthingId url should map to a predefined state just like any other state. Let's say that state is main.subthing. The process for loading the data, initiating the controller and rendering the UI should be exactly the same whether you get there by calling $state.go('main.subthing', {thing: 123, subthing: 456}) or ui-sref='main.subthing({thing: 123, subthing: 456})' or you paste myapp.com/thing/123/subthing/456 into the browser. They'll all end up at exactly the same place with exactly the same data by calling the exact same logic (most likely loading thing 123 and subthing 456 in resolves and injecting those into a controller).
You're right that if a url can't be handled by the application, that's a sign that something is wrong. Like I said, bad urls should be handled by defining otherwise when setting up states. But pasting a URL into a browser shouldn't require any extra work if your states are defined correctly. URL handling is baked into UI-Router by default.
I partially agree with you. The point where I disagree is when the URL is obtained by a user who is not supposed to access it. Quite often some websites implement authorization code to check if the user who is currently accessing the page is authorized to do so.
Also I think the route could be a bit different. Something like:
{thingid}/{mysubthingid}
This, I think is a cleaner URL and the parameters could be handled in the same way as the one in your example.
I suggest this in order to make it a bit difficult to unauthorized users.
Anyway, it definitely depends on the kind of application you are implementing. If the app's requirement is to be able to access the page by pasting the URL in the browser then I guess your approach is much better.
The biggest problem is that I even don't really know how to describe the problem I'm asking about. It's the first time in more then a decade of wed development.
I'm working on a Rails 4.1.1 app and using angularjs pretty extensively, though I don't know it well yet. And everything seemed to be working fine up to the moment when I tried to add some browser history manipulation to my app (e.g. changing the displayed url when listing though a paginated list so that that url can be copied and distributed). To do this I added a config to my app.
#app.config ($locationProvider) ->
$locationProvider.html5Mode(true)
And then in my angular controller added the $location binding like this
$scope.$watch 'pagination.cur', (newVal) ->
$scope.loadNews newVal
$location.path("/news").search({page:newVal})
(this is ment to change the url in the browser searchbox when the user goes from one page to another).
That workes well, the url does change appropriately, but all the sudden all the html links on the page got broken. I mean litteraly. I click any link on the page (even outside the controller div), the url in the serchbox changes appropriately, but the turbolinks toes not fire the Ajax request to get the new page content. If I then refresh the page, it loads the correct page.
I know it's really weird. What's weirder, that I don't get any JavaScript errors or anything unusual.
The only way I found to get the links working again - is to remove that initial config.
But when I do it, the $location falls back to hashtag syntax, wich is really not at all what I want.
My only assumption is that there could be some kind of a conflict between angular $location service and turbolinks when handling browser history, but even if that's right, I have no idea how to get around it. And I really need that kind of manipulation, 'cause I'm going to be using it alot in this and other apps.
I really don't know, what other information on this problem may be usefull, don't hasitate to ask for updates. I'll post whatever I can.
P.S. Btw, can this kind of manipulation be done by means of turbolinks? 'Cause it's exactly the same thing turbolinks does when changing the displayed url after page body reload, but I can't find any documentation on its public API for that.
UPDATE
Have no idea what's the source of the problem yet, but it seems to be not related to the turbolinks gem. Removing turbolinks requirements from the application.js file does not change anything.
Using $window.history.pushState instead of $location.path solves the functionality problem, but does not explain the initial bug.
