afletcher started a new conversation Npm Run Dev - Unable To Locate Dependency

I'm running laravel on homestead, and I'm trying to install a vue dependency via NPM.

npm version 6.7.0

I have successfully installed the module via NPM, however when I try to reference the module in my VUE file upon compiling it I get "module is not found error"

This dependency was not found:

* vuetify-material-dashboard in ./resources/js/app.js

To install it, you can run: npm install --save vuetify-material-dashboard

The module is there, and other modules installed are loaded correctly. (app.js)

import Vue from 'vue';
import VueRouter from 'vue-router';
import routes from './routes';
import VueResource from 'vue-resource';
import { TableComponent, TableColumn } from 'vue-table-component';
import Vuetify from 'vuetify';
import Card from 'vuetify-material-dashboard';

I have removed all node modules and reinstalled, deleted the package.json, ssh into the box environment / performed this all locally but the error still persists.

I've tried this, to no avail.


            async checkItem(item) {
                try {
                   await axios.get('http://api.crossref.org/journals/' + item.issn);
                   this.saveitem = true
                } catch (err) {
                    this.saveitem = false

                }
            },

 save() {

                if (this.editedIndex > -1) {

                }
                this.close()
            }

``` it returns false regardless of wether the API call fails or not

afletcher left a reply on Undefined Variable

I'm really unfamiliar with vue/js, so are you saying that console.log(this.$http); should return the variable from the save() function?

afletcher left a reply on Undefined Variable

NB, if I console.log(response) I get an Undefined.

afletcher started a new conversation Undefined Variable

I'm trying to wrap my head around promises. I am making an API call to check to see if an ISSN exists (via crossref).

I think this is an issue with promises, but I cant seem to get any of the stack overflow to fit with what I'm doing.

methods: {
  checkItem(item) {
                return new Promise((resolve, reject) => {

                    this.$http
                        .get("http://api.crossref.org/journals/"
                            + item.issn
                        )
                        .catch(function (error) {
                            console.log('hello')
                        })
                        .then(response => {
                          if(response.status = 200){
                              return true;
                          }
                          if(response.status = 404){
                              return false;
                          }
                           resolve();
                        })
                });
            },

            save() {

                if (this.editedIndex > -1) {
                    Object.assign(this.journals[this.editedIndex], this.editedItem)
            //edit in table and save via API call
                }
                this.close();

                if (this.editedIndex = -1) {
                    if(this.checkItem(this.editedItem)){
                        //save via api call

                }
                this.close()
            },
}

Any resources to help me? I'm struggling to grasp the concept.

afletcher left a reply on Searching Elasticsearch From Vue

Oh, the mounted() axios.get is just a call to test a restful API, to see if it worked before I implemented the elasticsearch

afletcher started a new conversation Searching Elasticsearch From Vue

Good afternoon!

I'm attempting to search my elasticsearch repository through vue + axios.

 import axios from 'axios';
    import { loadProgressBar } from 'axios-progress-bar'
    import 'axios-progress-bar/dist/nprogress.css'

    loadProgressBar();


    const query = {
        query: {
            match: {
                "_source": true

    }
        }
    };

    axios.get('http://test.lar:9200/output/_search', {
        params: {
            source: JSON.stringify(query),
            source_content_type: 'application/json'
        }
    }).then((res) => {
        console.log(res);
    });

    export default {


        data: function() {
            return {
                outputs: []
            }
        },


        mounted() {
            axios.get('/api/output')
                .then((response) => {
                    this.outputs = response.data;
                    console.log('Outputs loaded')
                })
                .catch((err) => {
                    console.log(err);
                });



        },

    }

Now if i curl / manually check the elasticsearch it works fine (http://192.168.10.10:9200/) returns repository status. However I'm getting an error message of

outputs:1 Access to XMLHttpRequest at 'http://test.lar:9200/output/_search?source=%7B%22query%22:%7B%22match%22:%7B%22_source%22:true%7D%7D%7D&source_content_type=application%2Fjson' from origin 'http://test.lar' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Now I don't have a CORS policy as far as I'm aware?

How do I rectify this, and what is a CORS policy?

afletcher started a new conversation Jobs And Queues - Best Practice

So I'm currently making an application which is downloading information from different API resources.

I have an output model which has a DOI (digital object identifier), and an abstract.

The majority of Output's information is derived from one API. I fire off a job and it collects all the information correctly.

I want to fire off a second job to get the Abstract from a different API.

The abstracts are in the Eutilz Pubmed Service and I've currently got the information through guzzle requests. This works fine for single jobs.

class ProcessAbstract implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public $tries = 1;
    public $timeout = 120;
    protected $output;


    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct(Output $output)
    {
        $this->onQueue('abstracts');
        $this->onConnection('redis');
        $this->output= $output;
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {

        Redis::funnel('key')->limit(1)->then(function () {
            // Job logic...
            $abstract = new AbstractFetcher($this->output);
            $abstract->fetch();
        }, function () {
            // Could not obtain lock...
            return $this->release(10);
        });
    }


}

class AbstractFetcher
{
    protected $output;
    public $apikey ='*************';


    public function __construct(Output $output)
    {
        $this->doi = $output->doi;
        $this->output = $output;
    }

    public function fetch(){

        //TODO check the response codes
    try{
        $client = LaravelGuzzleThrottle::client(['base_uri' => 'https://eutils.ncbi.nlm.nih.gov/']);
        $res = $client->get($this->getAPIUrl());
        Storage::append('Fuzzle.log', $res->getStatusCode());
        $xmlid = simplexml_load_string($res->getBody());
        $xmlid = $xmlid->IdList->Id->__toString();
        $client = LaravelGuzzleThrottle::client(['base_uri' => 'https://eutils.ncbi.nlm.nih.gov/']);
        $res = $client->get($this->getOutputUrl($xmlid));
        $xmlid = simplexml_load_string($res->getBody());

        if(isset($xmlid->PubmedArticle->MedlineCitation->Article->Abstract->AbstractText)){
            $stringpieces=[];
            foreach($xmlid->PubmedArticle->MedlineCitation->Article->Abstract->AbstractText as $text) {
                $stringpieces[]= (string) $text;
            }
            $abstract= implode(' ', $stringpieces);

            Output::where('doi', $this->doi)->update(['abstract' => $abstract]);
        } else {
            die();
        }

    } catch(Exception $e){
        Log::alert('Error with processing abstract');
        Log::alert('Output ID ' . $this->output->id);
        Log::alert('Error Message' . $e->getMessage());
        Log::alert('API Url ' . $this->getAPIUrl());
        Log::alert('Output Url ' . $this->getOutputUrl('test'));
    };


    }

        return  'https://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=pubmed&WebEnv=1&usehistory=y&term='.$this->doi . '$api_key=' . $this->apikey;
    }

    public function getOutputUrl($xmid){
        $field = array('db' => 'pubmed', 'retmode' => 'xml', 'rettype' => 'abstract', 'id' => $xmid);
        return "https://eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi?".http_build_query($field);
    }

}


It also correctly fetches all empty abstracts I for-loop through a collection of Outputs with empty abstracts as a single job.

class ProcessEmptyAbstracts implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public $tries = 1;
    /**
     * Create a new job instance.

    public function __construct()
    {
        $this->onQueue('abstracts');
        $this->onConnection('redis');
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {

        Redis::throttle('key')->allow(1)->every(5)->then(function () {
            $outputs = Output::where('abstract', null)->get();

            foreach ($outputs as $item) {

                $url = $this->getAPIUrl($item->doi);
                $xml_str = file_get_contents($url); //grab the contents
                $xml = new SimpleXMLElement($xml_str); //convert to SimpleXML

                // removes all the actual ones without any abstracts, content pages etc
                if (!empty($xml->ErrorList)) {
                    $outputs->forget($item->id);
                } // hasnt thrown an error so why is it not putting the abstract?
                else {
                    $xmlid = $xml->xpath('IdList/Id');
                    $xmlid = strval($xmlid[0]);
                    $curl = curl_init();

Now if I try to fire off the job through a model observer, it returns multiple errors of

I'm really sorry if this is obvious, but I have very limited PHP experience. I can't seem to understand why it intermittently fails one way but not another?

Thank you very much for the responses. Snapey's response helped me out massively.

Of note whereIn('id', $ids); threw an error

Integrity constraint violation: 1052 Column 'id' in where clause is ambiguous

which I fixed by prefixing the table name to the wherein

whereIn('categories.id', $id)

Like this?


 $cats = self::find($this->id)->Categories;
  

foreach ($cats as $item){
    $articles = Article::with(['categories' => function ($query) {
        $query->categoryID = $item->id;
}])->paginate(10);

except I don't seem to be able to pass the $item to the $query as its undefined

Also even if you set

  $cats = self::find($this->id)->Categories;
    $articles = Article::with(['categories' => function ($query) {

        $query->categoryID = 5;
}])->get();

    dd($articles);

its returning a collection of all the articles.

So if I'm reading this correctly.

As I have 3 tables (Articles, Categories and UserDetails) I would have to pull all the user categories

Then loop through it for each category and then pull out all the articles?

I have looked at the previous responses on the topic but I'm not sure it works for what I've set up. I have two pivot tables (unfortunately, I didn't follow the typical naming for the tables, as I couldn't find any information on how to name the columns for pivot tables) and hence my pivot tables have their own column names.

Each user has many categories. Each category has many articles. I want to retrieve all the articles from a set of categories which the user has.

So say a user has category 1, category 2, I want to retrieve all articles from category 1 and category 2.

For each of these belongsToMany relationships below, I have my own pivot tables.

article_categories

id | articleID | categoryId

users_cats

id | user_details_id | categories_id

Relationships.

Articles.php

public function categories()
{
    return $this->belongsToMany('App\Categories', 'article_categories', 'articleID', 'categoryID');
}
    

UserDetails.php


public function Categories()
{
    return $this->belongsToMany('App\Categories', 'users_cats', 'user_details_id', 'categories_id');
}
    

Categories.php

public function articles()
{
    return $this->belongsToMany('App\Article', 'article_categories', 'categoryID', 'articleID');
}


public function UserDetails()
{
    return $this->HasMany('App\UserDetails', 'users_cats', 'user_details_id', 'categories_id');
}
    

I have tried to use HasMany through but It doesn’t work with a many to many relationship as far as I can tell.

Currently (as a sort of “work around”) I've been using this.

  $user=\App\UserDetails::with(['categories.articles' => function($query){
            $query->orderBy('date', 'desc');

        }])->find($this->id);

        foreach($user->categories as $category)
        {}

        return $category->articles->unique();
    

However, I don’t think it will scale well with increasing data (it's already producing over 1k queries with only 1000 articles, taking over 8 seconds to load).
