kandi X-RAY | attachment_fu Summary
attachment_fu facilitates file uploads in Ruby on Rails. There are a few storage options for the actual file data, but the plugin always at a minimum stores metadata for each file in the database. There are four storage options for files uploaded through attachment_fu: File system Database file Amazon S3 Rackspace (Mosso) Cloud Files. Each method of storage many options associated with it that will be covered in the following section. Something to note, however, is that the Amazon S3 storage requires you to modify config/amazon_s3.yml, the Rackspace Cloud Files storage requires you to modify config/rackspace_cloudfiles.yml, and the Database file storage requires an extra table.

QUESTION
I am using Ruby on Rails and Kibana to show visualisation in my website(Ruby2.6.0, Rails5.2.3, Kibana6.6.1). By using Xpack->Share->Generate PDF/PNG, I find 'copy POST url'. I can get the following JSON file from the POST url by using 'net/http', but how can I use POST url/JSON file in my RoR website to download PNG file in 'assets' folder?
JSON file I got from POST url:
{'path': '/api/reporting/jobs/download/jvds4zs10qv79d0062b9cel6', 'job': {'id': 'jvds4zs10qv79d0062b9cel6', 'index': '.reporting-2019.05.05', 'type': 'esqueue', 'jobtype': 'PNG', 'created_by': False, 'payload': {'type': 'visualization', 'title': '[eCommerce] Sales by Gender', 'relativeUrl': "/app/kibana#/visualize/edit/ed8436b0-b88b-11e8-a6d9-e546fe2bba5f?_g=(refreshInterval:(pause:!t,value:0),time:(from:now-60d,mode:quick,to:now))&_a=(filters:!(),linked:!f,query:(language:lucene,query:''),uiState:(),vis:(aggs:!((enabled:!t,id:'1',params:(),schema:metric,type:count),(enabled:!t,id:'2',params:(field:customer_gender,json:'',missingBucket:!f,missingBucketLabel:Missing,order:desc,orderBy:'1',otherBucket:!f,otherBucketLabel:Other,size:5),schema:segment,type:terms)),params:(addLegend:!t,addTooltip:!t,isDonut:!t,labels:(last_level:!t,show:!t,truncate:100,values:!t),legendPosition:right,type:pie),title:'%5BeCommerce%5D+Sales+by+Gender',type:pie))", 'headers': 'uxY4w6gCRwwLZyFkDX0ujVlANYq7ae5UuNJAN0GpbTOX7vw5aPuCuyr37nNcpz3vtA8kNVaL6Gacs24mPjZfwl4mB9xRKGA62CkCLo8Xz1amuIEthI+BtKPGo5QAk2k2+7zLvLgX3KouVvYdd61U5rLAvfjv4TydcpH9qJ4qrL5OELkzAJGrNdujtDLWaoy2Qj9YXbLnh7gSdI+lrNml6usZIh4pMzz8qdRo597iO/4AeSJRa2JfAruyGB3zYInZRtMuCbA4f3ANvT2WeAn6lpiwThB993uEjwu4LBVUZuo2XL0TcB29YNNa9oMCUEhWjdJ1ase5VQdz8V2IOgecQ1W52V5JuVTvl9SkVvFWSBhXJg==', 'browserTimezone': 'Europe/Zurich', 'layout': {'dimensions': {'height': 589.234375, 'width': 866}}, 'basePath': '', 'forceNow': '2019-05-07T12:38:12.768Z'}, 'timeout': 120000, 'max_attempts': 3, 'priority': 10, 'browser_type': 'chromium'}}

ANSWER
Answered 2019-May-10 at 14:16I will answer my own question about what I tried in my project and close this question.
I got 'copy POST url' in 'Kibana->Visualisation/Dashboard->PDF/PNG'. It is a post url. I sent post request with this url to kibana server. The action will trigger kibana server to 'pending', 'processing' and generate the report. And I will get a JSON file back from the server. There is an important job ID in JSON file, like this 'jvi53ajd21w09d006233kcvo'. I can find all history reports in 'Management->Reporting'. Finally, I use the generated url 'http://localhost:5601/api/reporting/jobs/download/jvi53ajd21w09d006233kcvo' with 'wget' command to download the report in my local folder.
You can find similar answer here: https://discuss.elastic.co/t/how-to-use-post-url-to-share-visualisation-in-my-website/179671/4
Hope my answer can help those who want to use POST URL in Kibana.

I'm trying to push a forked repo to Heroku but Heroku won't accept the push because Ruby 2.3.1 wasn't accepted. I changed the version to 2.3.3 in the Gemfile and running bundle install --without production
, but oddly enough it was still considered to be 2.3.1. The same things happened even after trying other Ruby versions, such as 2.4.0.
