Im using the youtube data API and would like to template out my video search results but at the moment I'm a little confused about the paths to render out each piece of data, my data structure is, btw I'm using Backbone and parsing the response to return response.items.
Data
And my template looks like this:
<div class="video" title="{{snippet.title}}" id="{{id.videoId}}">
<img class="video-image" src="{{snippet.thumbnails.default.url}}">
<p class="video-title">{{snippet.title}}</p>
<p class="video-author">{{snippet.channelId}}</p>
<p class="video-description">{{snippet.description}}</p>
</div>
Also is this the correct type of search result data? How can I get likes/dislikes etc?
If I understand your problem correctly, you're having trouble getting the template to correctly render your data? If so:
The data you get back in response.items is an array, so you'll have to loop over them in the template.
Modify your template like this:
{{each results}}
<div class="video" title="{{snippet.title}}" id="{{id.videoId}}">
<img class="video-image" src="{{snippet.thumbnails.default.url}}">
<p class="video-title">{{snippet.title}}</p>
<p class="video-author">{{snippet.channelId}}</p>
<p class="video-description">{{snippet.description}}</p>
</div>
{{/each}}
Assuming you've compiled the Handlebars template into a variable called template, you can do this:
var context = {
results: response.items
};
var html = template(context);
Notice that the context object has a results property, which is the array that gets looped over with the {{each results}}.
Since you're using Backbone, you'll probably want to update the view with
this.$el.html(html);. Don't forget to return this; from the render method too!
As far as the type of search results data, I don't know if that's the right or wrong results...that's up to you. What kind of results do you want? Is the data you're getting what you're looking for?
If you want Likes/Dislikes, you have to look that up on a per-video basis. Register your application for the YouTube v3 API, and perform a GET request to the Videos resource (API Documentation). This will return a list of matching Videos (Video resource documentation), which have a likecount and dislikecount.

I hvae an angular view of a pdf preview that utilizes a controller to fill the view in. I am using pdflayer then to convert the html page into a pdf. The problem however is that no matter how I try and do this the scope variable values never make it into the pdf. I am basically trying to figure out a way to capture the angular view as an html string (data already injected) so that I can pass it to pdflayer. I have tried creating a directive and used replace within the directive then collecting the DOM as a string using .HTML().
For example:
I could like this
<div id="name">{{test.name}}</div>
to become this
<div id="name">Bob Smith</div>
It inevitably however turns into this when i use $('#name').html() and then console log it
<div id="name"></div>
or
<div id="name">{{test.name}}</div>
Any help would be appreciated even if the solution is to use a different method to create the pdf. Ultimately, I need to get a angular view into a formated pdf.
Please check if below library would work for you : https://www.npmjs.com/package/angular-save-html-to-pdf
So, over the past week I have looked at loading multiple galleries at once. I have been working in MeteorJS with blaze templates but, the methods I am using aren't working.
Essentially, all my data comes from multiple MongoDB collections which are organized in one main collection. When the website starts, I want to access the list of current collections and for each collection display a gallery of photos.
(Main Photo Page)
{{#each collections}}
{{>gallery collectionName=collectionName}}
{{/each}}
(Gallery Template)
<Template name="gallery">
{{getPhotos}}
</Template>
I have tried using a reusable blaze template that is fed the data and then runs a helper to display the images. It works, but I am having trouble loading only one template/collection at a time. I want to load one first, when that is done, load the next etc.
I have also wondered about using ReactJS for this with MeteorJS on the backend, but before I start, I'm wondering about how easy is it to load components one by one vs templates?
Thanks for any ideas or help!
You could try merging the cursors in a helper, instead of inside the template. This will force the order you like and still be reactive since the find is in a reactive context (the helper).
(HTML)
<Template name="gallery">
{{#each getPhotos}}
<img src="{{this.src}}">
{{/each}}
</Template>
(js)
'getPhotos':function(){
let mergedCursor = [];
for (collectionObject in Template.currentData().collections){
//not clear how you are getting the collections
mergedCursor.concat(collectionObject.find().fetch());
}
return mergedCursor;
}
You could also import the collections in the same js file and merge them directly.
I am confused on how to do a very, very trivial pattern with angular/firebase using angularfire.
Imagine you have a lil' old blog. You have some $scope.posts and you ng-repeat over them. Now you want to be able to click on one post and be routed to that post's page at '/posts/:id'. Since a $firebaseArray elements don't include their $id's how do you pass a unique id of a single post to the url and onto the postsCtrl?
<a ng-repeat="post in posts href="/posts/{{??????}}">{{post.title}}</a>
Update
The workaround I figured out is whenever I save a new post, I can save an attribute called "key" and then use this the way I would normally use the "id" attribute in every other framework.
$firebaseArray(postsRef).$add($scope.post).then(function(ref) {
ref.update({ key: ref.key()});
});
This hack, however, cannot be the solution to this simple, trivial, conventional pattern.
Thanks for any help.
You're instincts are right, that hack isn't the answer. Instead use angular's built in (key, value) option for ng-repeat:
<div ng-repeat="(id, post) in posts">
<a ng-href="/posts/{{post.id}}">{{post.title}}</a>
</div>

I've been at this for too long.
Basically, I'm pulling information via json.
This works fine, but the information being pulled does not show up as HTML.
I've been trying to get trustAsHtml to work but I do not know what I'm doing wrong.
Here's my code:
Controller:
var pageControllers = angular.module('pageControllers', ['ngSanitize']);
pageControllers.controller('PackagesCtrl', function PackagesCtrl($scope, $sce, $http){
$http.get('scripts/all_packages.php').success(function(data){
$scope.packagesData = data;
});
});
I'm getting groups of data from the database fine. My data is rendering pure text instead of showing the actual html eg: <p class="myClass">My Returned Data</p>
My Html has an ng-repeat="item in packagesData"
and in that div I have:
ng-bind-html="item.more_info".
This returns the data I need, but how would I now make them render properly? Basically, from the returned fields, I need 2 results to show up as html, but everything I try does not work.
My json file returns multiple rows of data, e.g.:
[{"title":"My Title", "more_info":"<p>Information</p>"},{"title":"My Title 2", "more_info":"<p>Information 2</p>"}]
How do I target specific results such as "more_info" to show as html?
basically you right on your path. What you need to do is to check if its the right value with key. Key is you identifier for particular value.
The thing you need to do is to use an ng-if condition.
<h2 ng-if="key=='more_info'" ng-bind-html="value"></h2>
I have an app that requires HTML to be pieced together from different APIs. Rather than getting into specifics there, let me just say that we have tried getting away from that many times but in the end the best answer always end up being what we currently have. Hopefully that changes someday but for now it's working great.
Currently, the HTML is parsed together as a string server-side using NodeJS and sent across the wire as complete HTML to be rendered. I'm in the process of adopting AngularJS, and while I'm loving it I am stuck on this issue-- how can I use Angular templating to insert invalid HTML at times?
The server will return three JSON fields: leadingHTML, trailingHTML, and copy. The copy field is always valid HTML, but leadingHTML and trailingHTML can sometimes return invalid HTML. When all three are added together, valid HTML results.
Let me illustrate:
leadingHTML='<figure>';
copy = '<img src="img1.jpg"/><img src="im2.jpg"/><figcaption>I love AngularJS</figcaption>';
trailingHTML='</figure>';
As you can see, if you add those together you will get the valid HTML that is required to be displayed. It's pretty easy to make the fields trustworthy HTML in Angular:
for (i in data.results){
data.results[i].copy=$sce.trustAsHtml(data.results[i].copy);
data.results[i].leadingHTML =$sce.trustAsHtml(data.results[i].leadingHTML );
data.results[i].trailingHTML =$sce.trustAsHtml(data.results[i].trailingHTML );
}
And then render the copy in my view:
<div ng-repeat='i in data.result'>
<p ng-bind-html='i.copy'></p>
</div>
But I need a way that does what this looks like it would do, but the leadingHTML and trailingHTML scope variables get render as strings:
<div ng-repeat='i in data.result'>
{{ i.leadingHTML }}
<p ng-bind-html='i.copy'></p>
{{ i.trailingHTML }}
</div>
Is the best answer here to build the template via javascript? Would that even work?
Are you able to pre-process your data so that you do have valid HTML?
var item;
for (i in data.results){
item = data.results[i];
item.content = $sce.trustAsHtml(item.leadingHTML + item.copy + item.trailingHTML);
}
Then you can just bind to the combined content in the view:
<div ng-repeat='i in data.results'>
<div ng-bind-html='i.content'></div>
</div>
Edit:
Yes, this will allow you to embed expressions in your HTML content.
In fact, you will need to be careful that you aren't opening yourself up to security exploits in the trusted HTML content (see the example at the bottom of the page for the $sce service).
Using $sce.trustAsHtml in this way is roughly equivalent to loading a directive's templateUrl from your site, so the security considerations around that are probably the same. See the "How does it work?" and
"Impact on loading templates".
