return true;
}
catch

this is my controller:
[Route("GetImageById/{id}")]
public bool GetImageById(string id)
{
ArticleModel articleModel = new ArticleModel();
var result = articleModel.GetImageById(id);
return result;
}
so basically this get the files from the path searching by file "Id".
And yes, this returns true.
How can i handle it to show the files on my dropzone? (mockfile)
I know there is an event, "addedfile", but i need some example.
It’s unclear what the use case for this is. Dropfile doesn’t access the server for a list of files (it just a JavaScript array). This might be useful if you are doing a custom thumbnail list, that is augmented by dropzone.
So when the user call "Edit view" i want to retrieve the stored files and show them on my Dropzone.
This approach is not going to work. In HTTP you get one file download. Even if the file were downloaded, JavaScript or Dropzone cannot select the file due to browser security. The user must select the file.
It is pretty easy to display links to a file and you have control over how the link is displayed.
You cannot use dropzones built in thumbnail list, you must write your own. You can use your custom thumbnail list instead of dropzones, so you have a common look. You probably will need a server thumbnail generator.
I know whats your point, but im telling you that i have a method returning this "C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png" on my Model.
wich is the same parameter used to create a Mockfile on the Browser when you hardcode the "call".
I just want to take this "C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png" from my Model List, put that on a variable on the front end and use it to be called/used by Dropzone javascript.
call "my variable"
please stop telling me that its not possible because i want to believe

Just serialize the model. Below is an ASP.NET core example.
public class FileModel
{
public string name { get; set; }
public int size { get; set; }
public string type { get; set; }
}
public IActionResult Index()
{
FileModel model = new FileModel()
{
name = "b0c88f23-818c-443c-91ce-3a8606a42c45_459.png",
size = 12345,
type = "image/png"
};
return View(model);
}
@model MvcDemo.Models.FileModel
@{
ViewData["Title"] = "Home Page";
}
<div class="text-center">
<h1 class="display-4">Welcome</h1>

var model = @Json.Serialize(Model);
console.log(model);

Basically, we have a view to edit an Article,
This view is a form, wich is fill with the data comming from the database for the related Article ( Name, Date expiration, etc ). And that works good.
On the server (folder path) i have stored some files related by GUID or Name to this Article.
So when the user call "Edit view" i want to retrieve the stored files and show them on my Dropzone.
A basic example will be usefull. Ill do the rest.

This way (hardcoded works) but ... must be a way to read values from the list on the Model:
//var mockFile = { name:"b0c88f23-818c-443c-91ce-3a8606a42c45_459.png", size: 12345, type: 'image/png' };//this.addFile.call(this, mockFile);
//this.options.thumbnail.call(this, mockFile, "C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png");
Dropzone Javascript:
jQuery(document).ready(function () { Dropzone.autoDiscover = false; $("div#myAwesomeDropzone").dropzone({ paramName: "file", maxFiles: 6, maxFilesize: 1200, maxFileHeight: 840, maxFileWidth: 840, acceptedFiles: ".png,.jpg", addRemoveLinks: true, parallelUploads: 6, init: function () { //var mockFile = { name:"b0c88f23-818c-443c-91ce-3a8606a42c45_459.png", size: 12345, type: 'image/png' }; //this.addFile.call(this, mockFile); //this.options.thumbnail.call(this, mockFile, "C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png"); this.on("thumbnail", function (file) { if ((file.height > this.options.maxFileHeight && file.width > this.options.maxFileWidth) || (file.height > this.options.maxFileHeight) || (file.width > this.options.maxFileWidth)) { alert("Image max size allowed is 840 x 840"); this.removeFile(file); var fs1 = new FormData(); fs1.append('file', file); fs1.append('fileguid', '@Model.ImageGuid'); $.ajax({ type: 'POST', url: '@Url.Action("Remove")', data: fs1, processData: false, contentType: false }); } }); this.on("sending", function (file, xhr, formData) { if (file.name.length > 12) { alert("Filename cant have more than 12 characters "); this.removeFile(file); var fs2 = new FormData(); fs2.append('file', file); fs2.append('fileguid', '@Model.ImageGuid'); $.ajax({ type: 'POST', url: '@Url.Action("Remove")', data: fs2, processData: false, contentType: false }); } this.on("maxfilesexceeded", function (file) { alert("The maximum amount of files was exceeded"); this.removeFile(file); var fs3 = new FormData(); fs3.append('file', file); fs3.append('fileguid', '@Model.ImageGuid'); $.ajax({ type: 'POST', url: '@Url.Action("Remove")', data: fs3, processData: false, contentType: false }); }); formData.append("file", file); formData.append("fileguid", '@Model.ImageGuid'); }); this.on("removedfile", function (file) { if (file.status == 'success') { var fd = new FormData(); fd.append('file', file); fd.append('fileguid', '@Model.ImageGuid'); $.ajax({ type: 'POST', url: '@Url.Action("Remove")', data: fd, processData: false, contentType: false }); } }); } }); });All-Star

You have a design bug. There's no reliable way for the web server to know where files are located on the client machines.
this.options.thumbnail.call(this, mockFile, "C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png");It seem to work on your development machine because it is both the server and the client. The folder stricture is the same.

I know, but the files are on my server. User will just choose an Article Id.
This file is on the server:
C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png
So that will be the same for all the users.
i see a code on my mind telling me something like:
Foreach File on my Model.List
(C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png)
Take name:
b0c88f23-818c-443c-91ce-3a8606a42c45_459.png as name,
Take .png as Type.
create mockfile with random size (1000 mb ?).
Then call C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\b0c88f23-818c-443c-91ce-3a8606a42c45_459.png
First file is added, continue looping,
C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\Another__________FILE____________ON________MY__________LIST.png

F. this i will do it by my own:
First, modify this:
public List<string> GetImageById(string id) { var parameters = new Dictionary<string, object> { { "id", id} }; ListFiles = GetContentsRestClient().Get<List<string>>("Article/GetImageById/{id}", parameters); return ListFiles; }Then... i add this:
public List<string>ListFiles { get; set; }Then i change this:
var mockFile = { name: "b0c88f23-818c-443c-91ce-3a8606a42c45_459.png", size: 12345, type: 'image/png' }; this.addFile.call(this, mockFile); this.options.thumbnail.call(this, mockFile, "@Model.ListFiles");now i just need to manipulate the filename and the type in another variables and this will work.

see docs for server files:
https://gitlab.com/meno/dropzone/-/wikis/FAQ
init: function () { var mockFile = { name:"@(Model.ImageGuid).png", // display name size: @Model.ImageSize, //size of image type: 'image/png' }; this.displayExistingFile(mockFile, "@Url.Action("GetImageByName", new {id = Model.ImageGuid}));then you need an action to return image:
public ActionResult GetImageByName (string id) { var path = "C:\Sitios Webs Test\appm_test.palermo.com.ar\Imagenes\" + id + ".png"; return File(path, "img/png"); }
