I have this dashboard (in angularjs) where you can see some files you uploaded through a custom service. In the interface, every object has its own file_id property. The service I use can generate an URL to download the file based on this id, but it's available only for 15 minutes (which is an inconvenient, but I have to work with it).
What I did was the following: when I click on the Download button in the interface, I make a call in the back-end to a service that generates a new URL (every time) and then sends it to front-end.
Here, I am trying to simulate a click on that link with the following code:
var downloadLink = document.createElement('a');
document.body.appendChild(downloadLink);
downloadLink.setAttribute('download', 'result.' + fileExtension);
downloadLink.setAttribute('href', downloadURI);
downloadLink.click();
The download it's working, but the filename is not the desired one (it's a random string - actually a hash that service is using - without an extension) and that can trick the inexperienced users.
Can I do something regarding this? Is there a better method to achieve this?
Thanks!

So what I'm trying to do is get text from a file in the same directory as my html file using JavaScript. I want to store an array inside a text file and change it whenever i want instead of constantly having to go into the code, save it, check if it works etc.
I've tried looking around but couldn't find any clear information, most of what I found is using .readAsBinaryString, etc..
I'm mostly seeing things like this but i can't seem find anything which is actually getting information from a textfile without making the person find the text file directory.
function storearray(newval){
var file = "file location;"
var txt = file.txt;
var array = txt.split("|");
txt = txt + newval + " | ";
return array;
}
To read a file from the user's disk you need to use FileReader and the user must explicitly select the file using a file input. (See JavaScript read file without using input).
To read a a file from the website you need to use Ajax (with fetch, XMLHttpRequest or a library that wraps around them like Axios). (See Using fetch from MDN).
If (as it seems here) you want to read data from the website but the website exists only on the user's disk then you still need to use Ajax but will usually run into security restrictions. Some browsers allow you to disable the security protection, but the general solution is to install a web server and load both HTML and the data file using HTTP.
Alternatively, you can store your data in JavaScript (you are generating an array from your text file, you can so that manually or have a build-time script do it) and just load it with a <script> element.
Similar to the uploading feature in fuelphp (link provided below), is there a tutorial for downloading files in fuelphp. There is not much information out there for fuelphp (other than the docs). Would I require a separate config page called download.php similar to upload.php?
All I really need is a page with either a download link or button to export csv to a user's local machine

Have you looked at the File class? This has a method of download which you pass the path of the file to. The 2nd param allows you to specify the name of the file that's downloaded.
File::download('path/to/file.txt, 'new-file-name.txt');
If you want to restrict downloads per user, you'll need to add logic around that.
https://fuelphp.com/docs/classes/file/usage.html#/method_download
Example
Create a new controller, as you've pointed out, download.php, and use the following as a starting point.
You'll need to pass something through to the get_index in order to determine which file the client will download. I'd suggest some sort of look up, using an unique identifier, instead of a file path, otherwise this would easily be exploited.
class Controller_Download extends Controller
{
public function get_index()
{
// #todo add logic surrounding file download
File::download('path/to/file.txt, 'new-file-name.txt');
}
}
How can we open a word document or pdf file by clicking on any link in Odoo? What are the steps need to be done?
1) Install module Document Management System (document).
2) Create directory (knowledge menu unit) or use existing one. Attach to this category required file (button "Attachments" above the form)
3) Since it was downloaded, it would generate an url. To access it: mouse right click on downloaded file - save url
4) Add the url to the website. Pressing it will download the file (publically available).
Note : Above Functionlity Work on odoo 8.
Document Management System module Remove in odoo 9 community and enterprice so this all file store in ir.attachment model.
So. Programatically, it is pretty much the same. The module 'document' allows to attach files to any object, including product.product (or product.template). So you have to find it:
attachment_ids = self.env['ir.attachment'].search([('res_model','=','product.product'),('res_id','=',product.id)]).
Where product.id - is id of needed product. E.g. you can store attachment_ids in product.product class as one2many field. After that you can get an url of any attachment. For example, for binary files:
for attach in attachment_ids:
url = 'https://yourcompany.com'+'/web/binary/saveas?model=ir.attachment&field=datas&filename_field=name&id='+str(attach.id)
This url may be easily added to the website product site, using foreach in product.attachment_ids
I've never worked with web pages before and I'd like to know how best to automate the following through programming/scripting:
go to http://financials.morningstar.com/ratios/r.html?t=GMCR®ion=USA&culture=en_US
invoke the 'Export to CSV' button near the top right
save this file into local directory
parse file
Part 4 doesn't need to use the same language as for 1-3 but ideally I would like to do everything in one shot using one language.
I noticed that if I hover my mouse over the button it says: javascript:exportKeyStat2CSV(); Is this a java function I could call somehow?
Any suggestions are appreciated.
It's a JavaScript function, which is not Java!
At first glance, this may seem like you need to execute Javascript to get it done, but if you look at the source of the document, you can see the function is simply implemented like this:
function exportKeyStat2CSV(){
var orderby = SRT_keyStuts.getOrderFromCookie("order");
var urlstr = "//financials.morningstar.com/ajax/exportKR2CSV.html?&callback=?&t=XNAS:GMCR®ion=usa&culture=en-US&cur=&order="+orderby;
document.location = urlstr;
}
So, it builds a url, which is completely fixed, except the order by part, which is taken from a cookie. Then it simply navigates to that url by setting document.location. A small test shows you even get a csv file if you leave the order by part empty, so probably, you can just download the CSV from the base url that is in the code.
Downloading can be done using various tools, for instance WGet for Windows. See SuperUser for more possibilities. Anyway, 'step 1 to 3' is actually just a single command.
After that, you just need to parse the file. Parsing CSV files can be done using batch, and there are several examples available. I won't get into details, since you didn't provide any in your question.
PS. I'd check their terms of use before you actually implement this.
The button directs me to this link:
http://financials.morningstar.com/ajax/exportKR2CSV.html?&callback=?&t=XNAS:GMCR®ion=usa&culture=en-US&cur=&order=asc
You could use the Python 3 module urllib and fetch the file, save it using the os or shutil modules, then parse it using one of the many CSV parsing modules, or by making your own.
this is my html code to make user to download a file and it is hitting controller
window.location.href="#routes.ListManagementController.downloadList("+listName+")?listname="+listName;
this is my controller code:
String listName = Form.form().bindFromRequest().get("listname");
response().setContentType("application/x-download");
response().setHeader("Content-disposition", "attachment;filename="+listName+"_data_export.csv");
The above two respose() statements make a pop up to download a file I want the browsed file location
File file = new File("C:/csv/" + filename);
So, using servlet api we can write the content into browsed file location using respose.getOutputStream() method. In play there are is no support for servlet. I want browsed file location selected by user so that i can give that location to File and write the file over there.
You can't get the location of a directory on the client, and even if you could, your server side could wouldn't be able to write to it (since it would usually be on a different computer).
