How to pass a Ruby variable to JavaScript? Sept 1, 2022 4:49:28 GMT

Post by egghead on Sept 1, 2022 4:49:28 GMT

My code snippet in index.erb :

<% @images.each do |obj| %>

<li>

<img src="<%= obj.image_uri %>" width="300px"></img>

</li>

<li>

Location:<%=obj.image_uri%>
</li>

I'd like to pass the value of obj.image_uri i.e., the path to the image file to JavaScript on the same page. But I have not found a way to do so.

Any help would be appreciated. Thanks

How about some like this:

<javascript>

....

var myurl = "<%= obj.image_uri %>"

...

</javascript>

Also you can provide a controller method with return string/json with your values and request it via ajax request from JS code.

Thanks, Dmitry, I tried your JS code suggestion, but its throwing error like :

Error: undefined local variable or method `obj' for #

Issue is how to pass the selected image to the JS code when I click on "Upload with JS" in my below code :

<script type="text/javascript">

// Upload file
function uploadFile() {

//var files = document.getElementById("filename").files;
//var files = RhoApplication.get_blob_path(@image.image_uri);
//var files = Rho.Application.publicFolder+"/images/DOG.jpg";
var files = "<%= obj.image_uri %>";
//var files = '/app/db/db-files/Image_05-27-2022_05.07.08_-000.jpg';
alert(files);

if(files.length > 0 ){

var formData = new FormData();
formData.append("file", files[0]);

var xhttp = new XMLHttpRequest();

// Set POST method and ajax file path
xhttp.open("POST", "http://10.179.22.89/demotest.php", true);

// call on request changes state
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {

var response = this.responseText;
if(response == 1){
alert("Upload successfully.");
}else{
alert("File not uploaded.");
}
}
};

// Send request with data
xhttp.send(formData);

}else{
alert("Please select a file");
}

}
</script>

<div data-role="page">

<div data-role="header" data-position="inline">
<h1>TAU Pictures</h1>
<a href="<%= Rho::Application.startURI %>" class="ui-btn-left" data-icon="home" data-direction="reverse" <%= "data-ajax='false'" if is_bb6 %>>
Home
</a>
<a href="<%= url_for :action => :new %>" class="ui-btn-right" data-icon="plus">
New
</a>
</div>

<div data-role="content">
<ul data-role="listview">
<li>
<a href="<%= url_for(:action => :edit)%>">Choose picture</a>
</li>

<% if System::get_property('has_camera') %>
<li>
<a href="<%= url_for(:action => :new)%>">Take picture</a>
</li>
<% end %>

<% @images.each do |obj| %>

<li>
<img src="<%= obj.image_uri %>" width="300px"></img>
</li>
<li>
Location:<%=obj.image_uri%>
<%@@img_path=obj.image_uri%>

</li>

<li>
<a href="<%=url_for(:action => :delete, :id => obj.object)%>">Delete</a>
</li>

<li>
<a href="<%=url_for(:action => :upload_file, :id => obj.object)%>">Upload with Ruby</a>
</li>
<li>
<input type="button" id="btn_uploadfile" value="Upload with JS" onclick="uploadFile();" >

</li>

<% end %>
</ul>
</div>

</div>

I would have preferred Rho's Ruby or JS way of uploading, but those also do not work (see upload_file method below) with my controller code :

require 'rho/rhocontroller'
require 'helpers/browser_helper'

class ImageController < Rho::RhoController
include BrowserHelper

@images = Image.find(:all)
render :back => '/app'

#realpath = Rho::Application.relativeDatabaseBlobFilePath(@image.image_uri)

How to pass a Ruby variable to JavaScript? Sept 4, 2022 20:03:09 GMT

Hi,

Error because your "obj" not defined in place where you add my code.
I see you has loop with define "obj" as current enumerated object.
So you should define array in javascript before you loop(enumeration by ruby code in ERB) and collect each obj inside your loop.

replace this:
var files = "<%= obj.image_uri %>";

to this:

var files = [];
<% @images.each do |obj| %>
files.push("<%= obj.image_uri %>");
<% end %>

How to pass a Ruby variable to JavaScript? Sept 7, 2022 4:44:40 GMT

Post by egghead on Sept 7, 2022 4:44:40 GMT

Thanks Dmitry. I'm very bad at JS. Sorry for the long post and the various ways I tried, but still pulling my hair out till date

Hope you will help me go for the best solution.

Try 1:

So I do a loop in JS like you suggested :

var files = [];
<% @images.each do |obj| %>
files.push("<%= obj.image_uri %>");
<% end %>

and I do get the path to the files array when I do :

alert(files);

But what I really wanted was to pass the path to only the one chosen file I try to upload from Ruby to JS, i.e., from my Ruby code within the loop:

to JS function uploadFile() without going through another controller method, but I do not know the way to do it.

Try 2:

I hard code the path to a picture of a dog existing in my project by doing :

var files = Rho.Application.publicFolder+"/images/DOG.jpg";

Here, also, when I do alert(files); it shows the correct path, but then the file never got uploaded.

Perhaps there is some problem with my webservice that is supposed to upload the file to the server.

Try 3:

Then I try with Rho JS style like so :

//Rho JS API

function upload_file_Rho_JS() {
// Upload the specified file using HTTP POST.
uploadfileProps = {
url: "http://10.179.22.89/demotest.php",
//filename: RhoApplication.get_blob_path(obj.image_uri),
//filename: Rho.RhoFile.join(Rho.RhoFile.join(Rho.Application.publicFolder, "images"), "backButton.png"),

filename: RhoApplication.publicFolder+"/images/DOG.jpg"

body: "uploading file",
fileContentType: "image/jpg"
};
alert(filename);

Rho.Network.uploadFile(uploadfileProps, upload_file_callback);

}

function upload_file_callback(params) {
// Check the result of the upload and act accordingly
if (params["status"] == "ok") {
alert("Upload Succeeded.");
} else {
alert("Upload Failed.");
}
}

but then the file never got uploaded although I get an "Upload Succeeded" popup!

Perhaps there is some problem with my webservice that is supposed to upload the file to the server.

Try 4 :

Then I try with pure Ruby code :

def upload_file
@image = Image.find(@params['id'])
realpath = Rho::RhoApplication::get_blob_path(@image.image_uri)
# Try hardcoding the image path
# realpath = Rho::Application.publicFolder+"/images/DOG.jpg"
puts 'realpath=' + realpath
Alert.show_popup(realpath)

if Rho::Network.hasNetwork
#Perform an HTTP GET request.
netProps = Hash.new
netProps['url'] = "http://10.179.22.89/demotest.php"
response=Rho::Network.get(netProps)
if response['status']!='ok'
Rho::WebView.executeJavascript("alert('No data connection or Webservice is down');")
Rho::WebView.navigate(url_for(:action=>:index))
end

## # Upload the specified file using HTTP POST.
uploadfileProps = Hash.new
uploadfileProps['url'] = "http://10.179.22.89/demotest.php"
uploadfileProps['body'] = "Uploading file"
#uploadfileProps['filename'] = Rho::Application.publicFolder+"/images/DOG.jpg"
uploadfileProps['file']=Rho::RhoApplication::get_blob_path(@image.image_uri)
#message = Rho::Application.publicFolder+"/images/DOG.jpg"
Alert.show_popup(uploadfileProps['file'])
uploadfileProps['fileContentType'] = "image/jpg"
#Alert.show_popup(uploadfileProps)

Rho::Network.uploadFile(uploadfileProps, url_for(:action => :upload_file_callback))
else
Rho::WebView.executeJavascript("alert('Network is not available');")
Rho::WebView.navigate(url_for(:action => :index))
end # has network
end

def upload_file_callback
puts "upload_file_callback params: #{@params}"
if @params['status'] == "ok"
Alert.show_popup "Upload Succeeded."
WebView.navigate( url_for :action => :index )
else
Alert.show_popup "Upload Failed."
WebView.navigate( url_for :action => :index )
end
end

but then the file never got uploaded although I get an "Upload Succeeded" popup!

Perhaps there is some problem with my webservice that is supposed to upload the file to the server.

Hi,

Please check your upload ruby code with our example: github.com/rhomobile/rhodes/blob/master/lib/commonAPI/coreapi/ext/Network.xml#L540-L556
I see you use wrong parameters name (file instead of filename).
Also - you should enable HTTP connections on iOS by special changes in main plist, because on iOS http connections not worked by default - only https
on iOS enable all http connections: github.com/rhomobile/rhodes/blob/master/res/generators/templates/application/build.yml#L117-L119
on iOS enabe list of http domains for connections: github.com/rhomobile/rhodes/blob/master/res/generators/templates/application/build.yml#L109-L110
do not forget remove "#"comment

@dmitry,

I have used the exact Ruby code as suggested by you as well as found in the documentation without modification.
I have only added one line in the callback :

puts "upload_file_callback params: #{@params}"

just to check on the response received from the server. I tried to upload with 3 webservices and I am giving hereunder each of their responses. File was never uploaded in any case :

test.php server response :

upload_file_callback params: {"rho_callback"=>"1", "body"=>"[{\"Status\":\"Failed\",\"Message\":\"The file could not be uploaded.\"}]", "http_error"=>"200", "status"=>"ok", "headers"=>{"connection"=>"Keep-Alive", "content-length"=>"66", "content-type"=>"text/html", "date"=>"Thu, 08 Sep 2022 08:48:32 GMT", "keep-alive"=>"timeout=15, max=100", "server"=>"Apache/2.2.14 (Ubuntu)", "vary"=>"Accept-Encoding", "x-powered-by"=>"PHP/5.3.2-1ubuntu4.30"}}

test1.php server response :

upload_file_callback params: {"rho_callback"=>"1", "body"=>"", "http_error"=>"200", "status"=>"ok", "headers"=>{"connection"=>"Keep-Alive", "content-length"=>"0", "content-type"=>"text/html", "date"=>"Thu, 08 Sep 2022 07:10:31 GMT", "keep-alive"=>"timeout=15, max=100", "server"=>"Apache/2.2.14 (Ubuntu)", "vary"=>"Accept-Encoding", "x-powered-by"=>"PHP/5.3.2-1ubuntu4.30"}}

demotest.php server response :

upload_file_callback params: {"rho_callback"=>"1", "body"=>"[{\"Status\":\"Failed\",\"Message\":\"The file could not be uploaded.\"}]\r\n\r\n", "http_error"=>"200", "status"=>"ok", "headers"=>{"connection"=>"Keep-Alive", "content-length"=>"70", "content-type"=>"text/html", "date"=>"Thu, 08 Sep 2022 08:57:00 GMT", "keep-alive"=>"timeout=15, max=100", "server"=>"Apache/2.2.14 (Ubuntu)", "vary"=>"Accept-Encoding", "x-powered-by"=>"PHP/5.3.2-1ubuntu4.30"}}

So how can I check further where the problem lies?
BTW, how does the Ruby code upload the file? Is it via a multi-part form?
Does the webservice require anything special for uploading the file?

Thanks again

Alex Epifanov, do you mean capture the whole request in the webservice?

Alex Epifanov, the webservices have been written by another person. When I contacted her, she says :

Parameters I can capture only those that has been sent through POST or GET. In those server responses, it should return something like :

The file abc.jpg could not be uploaded.

But the response you are getting is without the filename.

So it means that the file is not being sent through the app. I have included the filename in the echo to know if the filename is being captured by the API but it's not.

Through postman all the 3 webservices are working fine.

So, I feel either there is some bug with the Rhodes Ruby/JS file upload API or we need another webservice that actually has been tested as working with Rhodes API.

Would be thankful if pointers to any such webservice (preferably open source and in PHP) can be provided.

BTW, @dmitry, we are targetting Android only, not iOS, so the issue of https is not there. I'm using Camera::take_picture and Camera::choose_picture. Hope its not an issue.

Thanks

egghead you can run simplest webserver with Ruby to inspect incoming request. In fact that was what I just did. See the link at the end.
Here is a simple Rhodes app ( made with 7.5.0 ) with a button 'upload' under settings/index view, that runs upload with JS API, uploaded file is public/test.txt
There is also a server.rb, inspect its code it is very simple and straightforward. Run it, it will start HTTP server under port 8080 with /upload route exposed - it will inspect received requests and print it to console - so you can run both app and server and check which actual data is transferred. Modify and update it if you need further inspections.
I ran in on rhosim which has same network stack as Win32 target of rhodes so behavior should not differ. I can see that uploading a test file seems to work OK from the perspective of server: the endpoind reports to console correct data from the file uploaded:

- -> /upload

Alex Epifanov, Thank you. I got exactly the same output from server.rb
Similar output was observed in device logs even with our 3 php webservices
However, where will the uploaded file be located? I mean,no uploaded file was found! And whether an image file (.jpg/.png etc) can also be uploaded using the same code?

> However, where will the uploaded file be located? I mean,no uploaded file was found!

It should be implemented in server logic by yourself, or maybe available in your server software out of box. My example just idicates that server receives request from Rhodes with all required payload in multipart body: filename, size, actual data. Handling the request is server's job: to save received data to some file or anything else. That is out of hands of mobile app. You should refer to relevant RFC for multipart body, see:
en.wikipedia.org/wiki/MIME#Multipart_messages
www.ietf.org/rfc/rfc2388.txt

> And whether an image file (.jpg/.png etc) can also be uploaded using the same code?
Yes, it can. The content type for upload is application/octet-stream so you can pass binary data.
