how to stop iterating my like button inside my post - javascript

I am working on a post system with likes where the user can toggle the post`s like I have done everything correctly except the last step, the problem inside my v-for loop I fetch likes table from post-like relation(many to many since likes table has user_id and post_id) but it is iterating my button even when I add a condition look here-> duplicated like button, I have tried many things v-if, v-show I think the problem is with my algorithm I hope someone can fix that for me thanks.
<div class="panel panel-white post panel-shadow" v-for="post in posts" >
<div class="post-heading">
<div class="pull-left image">
<img v-bind:src="'img/profile/' + post.user.photo" class="img-circle avatar" alt="user profile image">
</div>
<div class="pull-left meta">
<div class="title h5">
<b>{{post.user.name}} </b>
made a post.
</div>
<h6 class="text-muted time">{{post.created_at | hour}}</h6>
</div>
</div>
<div class="post-description">
<p>{{post.content}}</p>
<div class="stats">
<button class="btn btn-default stat-item" #click.prevent="addLike(post.id)">
<i class="fa fa-thumbs-o-up" aria-hidden="false" style="color: blue" v-for="(like) in post.likes" v-bind:style="like.user_id===id && like.post_id===post.id?'color: blue;':'color: gray;'" > Like {{post.likes.length}}
</i> <!-- here is the duplicate problem-->
</button>
<a class="btn btn-default stat-item" #click.prevent>
<i class="fa fa-reply-all"> {{post.comments.length}}</i> Comments
</a>
</div>
</div>
<comment-input :post="post" :userId="id" :userPhoto="userPhoto"></comment-input>
<ul class="comments-list" v-for="comment in post.comments?post.comments:''">
<comments :comment="comment" :userId="id" :userPhoto="userPhoto"></comments>
</ul>
</div>
<hr>
</div>
</div>


Don't loop through the button element, try to use a method likedBythisUser to check if the current user liked the post in order to bind it to the button style :
methods:{
likedBythisUser(post,id){
return post.likes.find(like=>{
return like.user_id===id && like.post_id===post.id;
}) // return a boolean value
}
}
template :
<button class="btn btn-default stat-item" #click.prevent="addLike(post.id)">
<i class="fa fa-thumbs-o-up" aria-hidden="false" style="color: blue" bind:style="likedBythisUser(post,id)?'color: blue;':'color: gray;'" > Like {{post.likes.length}}
</i> <!-- here is the duplicate problem-->
</button>

Vue js edit content according to its ID

I’m starting with vue js and I’m listing some data from database. More specifically posts with title, description and images.
I have Edit and Delete buttons. All posts are loaded using v-for. So when I click to edit one post, all the posts are “openning” to be edited.
I need to open the editing only in one post at a time. I mean, the specific post I really want to edit.
I made some progress with title input and with image delete badge but still need to work on Save and Cancel buttons (they open in all posts) and input files (when I choose files in second post for example, they load into first post).
<div id="app" class="row mb-50">
<div v-for="(item, index) in tours" v-bind:key="item.id" id="tours" class="col-md-12 mb-30">

Update
If I use
<button #click="editTour(item)" v-if="editingTour == item.id" class="btn border btn-circle tour-list-edit-btn">Save</button>
all others Save buttons get hidden.

I think you can use add to each object of list new property isEditing and look for it in each item of the loop to check Save/Edit show.
Now your one prop editingTour can't be used for multiple edit, it can't store array of edited items id.
Template of buttons would look like:
<span>
<button #click="item.isEditing = item.id" v-if="!item.isEditing"
class="btn border btn-circle tour-list-edit-btn">Edit</button>
</span>
<span>
<button #click="editTour(item)" v-if="item.isEditing"
class="btn border btn-circle tour-list-edit-btn">Save</button>
</span>
<span>
<button #click="clearInput(item)" v-if="item.isEditing"
class="btn border btn-circle tour-list-delete-btn">Cancel</button>
</span>
<span>
<button #click="deleteTour(item.id, index)" v-if="!item.isEditing"
class="btn border btn-circle tour-list-delete-btn">Delete</button>

</a>
</li>
please help me to get the value of "s" with out using the ng-click, so that i can send the value of "s" to the controller A for the save function.

Just a suggestion, Can't we create a variable named "selectedTab" and when you click the tab just generate a KeyUp event from that tab and in this event you can change the value this variable and while posting just get the value from that "selectedTab" variable.
For reference how to generate an click event

unexpected closing tag angular error

Writing an angular app in bulma, copied the template directly from the template site for testing and I get this error. I have checked and checked and everything is closed properly, yet somehow I keep getting an unclosed nav error. Oddly enough when I delete the closing nav tag, the site compiles correctly, but is broken. I have no idea what to do.

Error
`compiler.js:486 Uncaught Error: Template parse errors:
Unexpected closing tag "nav". It may happen when the tag has already
been closed by another tag. For more info see
https://www.w3.org/TR/html5/syntax.html#closing-elements-that-have-

</div>
</div>
[ERROR ->]</nav>
</div>`

in my case I was forgetting a detail in the tag
<button class="btn btn-primary" (click) "handleClickMe()
">Click me !</button>
I forgot to put the "=" in (click)="handleClickMe()

Usually if you see an "Unexpected closing tag <something>" the problem isn't actually with that <something> but rather with an adjacent element that hasn't been properly closed. Paste stuff here: https://validator.w3.org or any similar HTML validator service, or use a better editor/IDE that offers syntax highlighting to help you find these errors.
You are missing a closing </div> tag.
You close navbar-brand, navbar-menu and navbar-end but you do not close <div class='container'>
As this missing </div> tag ought to be directly before </nav>, you get the error telling you, in fact, exactly where you ought to look. "I found a </nav> I wasn't expecting to see!" ... Ok, so go look at wherever you have a </nav> and figure out what element nearby is missing or has typos, etc.

Adding for future reference, for Angular
I've also seen this where you have invalid html like this
<p>
<div>
</div>
</p>
Change the p to a div and it'll work

Value of object inside json object is not evaluating in nested ng-repeat

My app has a web service that returns the following json array
[{"id":1,"title":"Jeans #1","description":"Jeans Description Of Jeans #1","gender":1,"waists":[{"id":1,"sizeString":"28","enabled":true,"gender":1},{"id":3,"sizeString":"30","enabled":true,"gender":1}],"inseams":[{"id":1,"sizeString":"28","enabled":true,"gender":1},{"id":2,"sizeString":"29","enabled":true,"gender":1}],"style":{"id":1,"styleName":"Style #1","enabled":true,"gender":1},"ctr":0,"colorAndPatterns":[{"id":2,"description":"Green","background":"#00FF00","enabled":true,"gender":1},{"id":1,"description":"Red","background":"#FF0000","enabled":true,"gender":1}],"productOverviews":[{"id":3,"description":"Straight leg","enabled":true,"gender":1},{"id":1,"description":"Slim through thigh","enabled":true,"gender":1}],"enabled":true,"firstJeansImagesBycolor":[{"id":2,"colorAndPatternId":2,"enabled":true},{"id":6,"colorAndPatternId":1,"enabled":true}],"allJeansImagesByColor":[{"id":1,"colorAndPatternId":2,"enabled":true},{"id":2,"colorAndPatternId":2,"enabled":true},{"id":3,"colorAndPatternId":2,"enabled":true},{"id":4,"colorAndPatternId":2,"enabled":true},{"id":5,"colorAndPatternId":1,"enabled":true},{"id":6,"colorAndPatternId":1,"enabled":true},{"id":7,"colorAndPatternId":1,"enabled":true},{"id":8,"colorAndPatternId":1,"enabled":true}]}]
I am using angular's ng-repeat directive to iterate through the json array in the following manner
<div ng-repeat="jean in currentJeans">
<div class="col-xs-4 jeans-listing at-repeat-twirl-in at-repeat-twirl-out" ng-repeat="colors in jean.colorAndPatterns | filter:{id:currentColorId}">
<a href="#/jeans-details/{{jean.id}}" class="thumbnail">
<img ng-src="static/images/jeans/{{jean.id}}/{{colors.id}}/{{jean.firstJeansImagesBycolor[$index].id}}.jpg" alt="Jeans Image"/>
<div class="caption">
<h5 class="text-center">{{jean.title}}</h5>
</div>
<button class="btn btn-default btn-sm" style="position: absolute;top:100px;left:30%;display:none;color:white;background-color:rgba(0,0,0,0.4)"><i class="fa fa-search"></i> Quick View</button>
</a>
</div>
</div>
The problem i 'm facing is this expression evaluates to nothing
{{jean.firstJeansImagesBycolor[$index].id}}
Is this the right way to access arrays inside json objects or not what i 'm doing wrong ??
Here is the link to JSFiddle

It is working perfectly fine. I just printed the path given and it prints:
http://jsfiddle.net/pfgkna8k/3/
<div ng-app="lists">
<div ng-controller="ProductList">
<div ng-repeat="jean in currentJeans">
<div class="col-xs-4 jeans-listing at-repeat-twirl-in at-repeat-twirl-out" ng-repeat="colors in jean.colorAndPatterns | filter:{id:currentColorId}">
<a href="#/jeans-details/{{jean.id}}" class="thumbnail">
<img ng-src="static/images/jeans/{{jean.id}}/{{colors.id}}/{{jean.firstJeansImagesBycolor[$index].id}}.jpg" alt="Jeans Image"/>
