Laravel + Vue unable to save data to my database - php

Question

I'm trying to save data from my vue component to database but it will just say 500 (internal server error ) on my dev tools.
I tried one by one deleting my code to see where it fails everything will work fine until the I added the save(); function to my database
Vue Component
<template>
<form #submit.prevent="submit">
<div class="form-group">
<input type="text" class="form-control" name="name" id="name" v-model="fields.name" />
<div v-if="errors && errors.name" class="text-danger">{{ errors.name[0] }}</div>
</div>
<div class="form-group">
<input type="text" class="form-control" name="post" id="post" v-model="fields.post" />
<div v-if="errors && errors.post" class="text-danger">{{ errors.post[0] }}</div>
</div>
<button type="submit" class="btn btn-primary">Send message</button>
<div v-if="success" class="alert alert-success mt-3">
Message sent!
</div>
</form>
Vue COmponent Script
<script>
export default {
data() {
return {
fields: {},
errors: {},
success: false,
loaded: true,
}
},
methods: {
submit() {
if (this.loaded) {
this.loaded = false;
this.success = false;
this.errors = {};
axios.post('/adminquickannc', this.fields).then(response => {
this.fields = {}; //Clear input fields.
this.loaded = true;
this.success = true;
}).catch(error => {
this.loaded = true;
if (error.response.status === 422) {
this.errors = error.response.data.errors || {};
}
});
}
},
},
}
</script>
Controller // My controller code to save it on the database
use App\Post;
use Illuminate\Http\Request;
public function store(Request $request)
{
// Validation
$this->validate($request, [
'name' => 'required',
'post' => 'required|max:500|min:10'
]);
// Variables we needed
$name = $request->input('name');
$post = $request->input('post');
// Saving the post to database
$post = new Post();
$post->name = $name;
$post->post = $post;
$post->save();
}
I expect this code to save data to my database, is this way of saving it safe? and can you guys give me tools where errors like this can be more specific so i can understand where it fails Thank you in advance guys!
