Get response data from axios in vue.js - vue.js

Question

I am trying to get the response data from my REST API and to display it in my vue.js application as follows:
var database = new Vue({
el: '#database',
data: {
databaseConfiguration: {
type: '',
url: '',
port: '',
username: '',
password: ''
},
errors: []
},
created: function () {
axios.get('/config/database')
.then(function (response) {
this.databaseConfiguration = response.data;
console.log(response.data);
})
.catch(function (error) {
this.errors.push(error);
console.log(error);
})
}
}
)
If I debug it, I see that the response is correctly fetched from the REST API. But unfortunately the data is not displayed on the html page.
The html code looks as follows:
<div id="database" class="panel panel-default panel-primary">
<div class="panel-heading">
<h3 class="panel-title">Database Configuration</h3>
</div>
<div class="panel-body">
<form class="form-horizontal">
<div class="form-group">
<label for="inputType" class="col-sm-2 control-label">Type</label>
<div class="col-sm-10">
<input type="text" v-model="databaseConfiguration.type" class="form-control" id="inputType"
placeholder="Database type">
</div>
</div>
<div class="form-group">
<label for="inputUrl" class="col-sm-2 control-label">Url</label>
<div class="col-sm-10">
<input type="text" v-model="databaseConfiguration.url" class="form-control" id="inputUrl"
placeholder="Url">
</div>
</div>
<div class="form-group">
<label for="inputPort" class="col-sm-2 control-label">Port</label>
<div class="col-sm-10">
<input type="number" v-model="databaseConfiguration.port" class="form-control" id="inputPort"
placeholder="Port">
</div>
</div>
<div class="form-group">
<label for="inputUsername" class="col-sm-2 control-label">Username</label>
<div class="col-sm-10">
<input type="text" v-model="databaseConfiguration.username" class="form-control"
id="inputUsername" placeholder="Password">
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="col-sm-2 control-label">Password</label>
<div class="col-sm-10">
<input type="password" v-model="databaseConfiguration.password" class="form-control"
id="inputPassword" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Save</button>
</div>
</div>
</form>
</div>
</div>

Your this is pointing to the wrong object in your callbacks. Try using an arrow function, a closure, or bind.
Here is an example using an arrow function.
axios.get('/config/database')
.then(response => {
this.databaseConfiguration = response.data;
console.log(response.data);
})
.catch(error =>{
this.errors.push(error);
console.log(error);
})
See How to access the correct this inside a callback.
