How do i Fix api data not displaying with vue and axios - django

I can't seem to load the data information on the html table from the api via using vue and axios
I am adding vue as my frontend to my rest api and i have called the api correctly using axios the problem i am having is there is no data shown but the loop displays the number of lines cos i have 3 entries and the table shows 3 empty spaces but no meaningful data and there's no console error please what ami i doing wrong ?
<div class="body">
<table class="table table-bordered table-striped table-hover dataTable ">
<thead>
<tr>
<th>Article Id </th>
<th>Title</th>
<th>Body</th>
<th>Edit</th>
<th>Delete</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Article Id </th>
<th>Title</th>
<th>Body</th>
<th>Edit</th>
<th>Delete</th>
</tr>
</tfoot>
<tbody>
<tr v-for="article in articles" :key="article.article_id">
<td>{{ article.article_id }}</td>
<td>{{ article.article_title }}</td>
<td>{{ article.article_body }}</td>
<td><button #click="geArticle(article.article_id)" class="btn btn-round btn-primary">Edit</button></td>
<td><button #click="deleteArticle(article.article_id)" class="btn btn-round btn-danger">Delete</button></td>
<td></td>
</tr>
<script>
new Vue({
el: "#startapp",
data: {
articles: [],
// loading: false,
currentArticle: {},
message: null,
currentArticle: {},
newArticle: {'article_title': null, 'article_body': null}
},
mounted(){
this.getArticles();
},
methods: {
getArticles: function() {
axios({
method: 'get',
url: '/api/article'
}).then((response) => this.articles = response.data)
}
}
});
</script>
The data from the api is supposed to show the article_id, article_title and article_body but i get blank spaces and there is no error

One of the things that is likely to go wrong especially as there are no error messages showing is forgetting to run your json-server package. This should run simultaneously as your development tools.
First run:
npm run json
While the above is still running, open another terminal and run this:
npm run serve

How to get table row values in a javascript function from a dynamically created table using for loop in django?

So basically, I am passing a context from views to my template.
In my template I am using 'for loop' to view the context in a tabular form and also attaching a button for every table row.
When that button is clicked, I want to call a javascript function(that has ajax call).
I need to get values of row elements for that particular row to use in my function.
My view function:
def asset_delivery(request):
deliverylist = Delivery.objects.filter(status='Added to Delivery List')
context = {'deliverylist': deliverylist}
return render(request, 'gecia_ass_del.html', context)
So far I tried passing those values as parameters in the following way.
My html template table:
<table class="table">
<thead style="background-color:DodgerBlue;color:White;">
<tr>
<th scope="col">Barcode</th>
<th scope="col">Owner</th>
<th scope="col">Mobile</th>
<th scope="col">Address</th>
<th scope="col">Asset Type</th>
<th scope="col">Approve Asset Request</th>
</tr>
</thead>
<tbody>
{% for i in deliverylist %}
<tr>
<td id="barcode">{{i.barcode}}</td>
<td id="owner">{{i.owner}}</td>
<td id="mobile">{{i.mobile}}</td>
<td id="address">{{i.address}}</td>
<td id="atype">{{i.atype}}</td>
<td><button id="approvebutton" onclick="approve({{i.barcode}},{{i.owner}},{{i.mobile}},{{i.address}},{{i.atype}})" style="background-color:#288233; color:white;" class="btn btn-indigo btn-sm m-0">Approve Request</button></td>
</tr>
{% endfor %}
</tbody>
</table>
The table is displayed perfectly but the button or the onclick or the function call does not seem to work.
My javascript function:
<script>
function approve(barcode2, owner2, mobile2, address2, atype2){
console.log('entered approved');
var today = new Date().getFullYear()+'-'+("0"+(new Date().getMonth()+1)).slice(-2)+'-'+("0"+new Date().getDate()).slice(-2);
$.ajax({
type:'POST',
url: 'deliveryupdate/'+barcode+'/',
dataType: 'json',
data:{
barcode: barcode2,
owner: owner2,
mobile: mobile2,
address: address2,
atype: atype2,
status:'Authority Approved',
statusdate: today,
csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val()
},
beforeSend: function() {
console.log('before send');
},
success: function(){
console.log("success log");
swal("Success!","Asset request has been approved","success");
},
error: function(){
console.log("error");
}
});
}
</script>
I checked the browser logs and it looks like the function is not getting executed, meaning the problem lies with the function call or the button. Please help.
The code is working on my end. I have reduced the function to:
function approve(){console.log('entered approved');}
without any parameters and 'entered approved' is logged to the console. Check if you are setting the correct parameters and if the console throws an error. Simplify your function and add the parameters one by one in order to troubleshoot this.

Fetch and display Data from Django Rest Api

after followed many tutorials about how to integrate Django rest in React i successed to fetch data from my api like this , but the header of my table repeat himself by the numbers of objects i fetch from my data , i have 3 products in my data so that is make the table 3 times .
When i try to move the {this.state.todos.map(item => ( just before my i get an error because that "break" my tag , so i can put {this.state.todos.map(item => ( just before my or just after , someone can help me plz ? i just want to repeat the for each item but not all the table , thanks you for help
Render of my table in the local server
import React, { Component } from 'react';
class Products extends Component {
state = {
todos: []
};
async componentDidMount() {
try {
const res = await fetch('http://127.0.0.1:8000/api/');
const todos = await res.json();
this.setState({
todos
});
} catch (e) {
console.log(e);
}
}
render() {
return (
<div>
{this.state.todos.map(item => (
<table class="table table-bordered table-hover table-striped">
<thead>
<tr class="bg-gray text-white">
<th>Id</th>
<th>Category</th>
<th>Name</th>
<th>Short Description</th>
<th>Price</th>
<th class="text-center">Image</th>
<th>Delete</th>
</tr>
</thead>
<tbody>
<tr>
<td scope="row">{item.title}</td>,
<td scope="row"></td>,
<td></td>
<td></td>
<td></td>
<td></td>
<td>Delete</td>
</tr>
</tbody>
</table>
))}
</div>
);
}
}
export default Products;
You're mapping over the whole table. This will map each item to a row:
class Products extends Component {
state = {
todos: []
};
async componentDidMount() {
try {
const res = await fetch('http://127.0.0.1:8000/api/');
const todos = await res.json();
this.setState({
todos
});
} catch (e) {
console.log(e);
}
}
render() {
return (
<div>
<table class="table table-bordered table-hover table-striped">
<thead>
<tr class="bg-gray text-white">
<th>Id</th>
<th>Category</th>
<th>Name</th>
<th>Short Description</th>
<th>Price</th>
<th class="text-center">Image</th>
<th>Delete</th>
</tr>
</thead>
<tbody>
{this.state.todos.map(item => (
<tr>
<td scope="row">{item.title}</td>,
<td scope="row"></td>,
<td></td>
<td></td>
<td></td>
<td></td>
<td>Delete</td>
</tr>
))}
</tbody>
</table>
</div>
);
}
}

Bootstrap-table: Server Side pagination + nextPage method

I'm using Django and the app Bootstrap-table to correctly format my tables.
I've got a lot of data so I'm using a server-side pagination. It's working great.
Now I'd like to implement some method like a nextPage method.
By combining the example jsfiddle of server-side pagination + method nextPage, it doesn't work : Clicking on the button nextPage does nothing even if it's bound to nextPage method:
http://jsfiddle.net/ThePhi/msj2apLb/1/
<button id="button2" class="btn btn-default">nextPage</button>
<table data-toggle="table"
data-url="http://issues.wenzhixin.net.cn/examples/bootstrap_table/data"
data-pagination="true"
data-side-pagination="server"
data-page-list="[5, 10, 20, 50, 100, 200]"
data-search="true"
data-height="300">
<thead>
<tr>
<th data-field="state" data-checkbox="true"></th>
<th data-field="id" data-align="right" data-sortable="true">Item ID</th>
<th data-field="name" data-align="center" data-sortable="true">Item Name</th>
<th data-field="price" data-sortable="true">Item Price</th>
</tr>
</thead>
</table>
<script>
var $table = $('#table'),
$button2 = $('#button2');
$(function () {
$button2.click(function () {
$table.bootstrapTable('nextPage');
});
});
</script>
I forgot to put id="table" ...

How to Use Jquery Datatables in Ember 2.0

I picked up learning emberJS lately and I have had issues doing some basic things I would have done while not using this framework. The main issues I have had was using jquery plugins, in this case jquery datatables
in my component's component.js
import Ember from 'ember';
export default Ember.Component.extend({
didInsertElement: function(model){
Ember.run.scheduleOnce('afterRender', this, function(model) {
this.$(".datatables").DataTable();
});
}
});
in my component's template.hbs
<table class="table table-hover datatables">
<thead>
<tr>
<th>Course Name</th>
<th>Course Title</th>
<th class="text-center">Actions</th>
</tr>
</thead>
<tbody>
{{#each courses as |course|}}
<tr>
<td> {{ course.name }} </td>
<td> {{ course.title }} </td>
<td class="text-center"> {{#link-to 'courses.edit' course }} Edit {{/link-to}} </td>
</tr>
{{/each}}
</tbody>
</table>
**then i used the component like :- **
{{#course-datatable courses=model}}{{/course-datatable}}
I would appreciate a demo accompanied with answers.
cheers
Ok so i haven't done a component of the jquery datatable plugin. But yes for other Jquery plugins, it would be more or less like this. If you are building your own component:
Add the Datatable js files to include inside your BrocFile
Run in ember client
ember g my-jquery-datatable
this will generate the component in the generated hbs fill in the general html you would use
<table id="example" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Name</th>
<th>Position</th>
</tr>
</thead>
{{#each modelWithData}}
<tr>
<td>this.name</td>
<td>this.position</td>
</tr>
{{/each}}
</table>
then on you js generated file initiate the plugin in the didInsertElementMethod
export default Ember.Component.extend({
didInsertElement(){
this.$('#example').DataTable();
}
});
then to be able to use this table in other components or controllers you can do
{{my-jquery-datatable modelWithData=otherArrayWithTheTableAttributes}}
Hope it helps

Ember list of checkbox on check one send rest

I have a list of checkboxes in my template:
<table>
<thead>
<tr>
<th></th>
<th>Sender</th>
<th>Title</th>
</tr>
</thead>
<tbody>
{{#each message in model.entities}}
<tr>
<td class="cell-star">
{{input type="checkbox" name=message.id tabindex=message.id class="starBox" checked=message.isStar }}
</td>
<td class="cell-broadcaster">
{{message.notification.autor.firstName}} {{message.notification.autor.lastName}}
</td>
<td class="cell-title">
{{#link-to 'notifications.details' message.notification.id}}{{message.notification.title}}{{/link-to}} {{#unless message.isRead}} (new) {{/unless}}
</td>
</tr>
{{/each}}
</tbody>
</table>
And now i want to send rest query every time when i change some of the checkbox state with id of changed checkbox.
What should i write in my controller?
i have tried something like that but i cannot get data of changed checkbox:
updateStarStatus: function() {
console.log('checkbox clicked');
//here should be something like that:
//$.getJSON(apiHost + "/api/forum/star/"+id);
}.observes('model.entities.#each.isStar'),
im not using emberData. My model looks like this:
model: function() {
return $.getJSON(apiHost + "/api/forum");
},
You could use the observesBefore method to track the changes and make a diff in the observes method, but I'd rather use the native on change event, to trigger an action and pass the object:
<div {{action "updateStarStatus" message on="change"}}>
{{input type="checkbox" checked=message.isStar}}
and in the controller
actions: {
updateStarStatus: function(message) {
alert(message.id)
}
}
