Allowing users to download files

Hi psysak,

What is the purpose of the file store in Mango?

This very thing! Well, and other things. Really anything that involves files (note we moved Excel Report templates into filestores, for instance). That will give you permissions control if required. You can see on the /ui/administration/file-stores page the available file stores, or create a new one. Files placed in there can be downloaded with a simple GET for an authenticated user who has permissions to the file store, with something like GET /rest/v2/file-stores/{FILE STORE NAME}/path/in/filestore/to/file.extension (which can be done in an <a/> tag if you know the store and path). There are also endpoints to list files at locations, and to create filestores. The UI doesn't currently support creating a filestore or changing the read/edit permission. But, you can enable swagger and explore the endpoints at /swagger-ui.html (restarting Mango would be required) or the table definition is pretty easy and you could create a file store via the SQL console, like insert into fileStores (storeName, readPermission, writePermission) values ('CustomStore', 'anybody', 'superadmin');

So any user with the permissions of 'anybody' would be able to download files from there.

Hey guys, thanks for the answer. @phildunlap when you say there are endpoints to list files is that usable for dynamic tables? Ie if I add a folder to a file can I have a table on a page which will then auto add that new file to the table?

phildunlap

Yes. Somebody else may give a better answer, but assuredly the file store page is just such a dynamic table at the end of the day. You could figure out how to adapt the directives at play there or use the returned file listings in an ng-repeat to have the dynamic table.

Ie if I add a folder to a file can I have a table on a page which will then auto add that new file to the table?

Assuming you mean add folder to file store? I'm not sure if there's a file store websocket that you could use to update it live if someone else modified it, if that's what you're asking. I bet @Jared-Wiltshire knows.

@psysak You can use the file store browser component, unfortunately there's no attribute to hide the upload/move/delete buttons yet (the file stores were originally admin only and the component was designed for this). If the user doesn't have write permission these buttons will not work however.

<ma-file-store-browser ng-model="maFileStoreBrowserModel" store="default" disable-edit="true"></ma-file-store-browser>

psysak

@Jared-Wiltshire there isn't a way to pass a specific path to that component is there?

Jared Wiltshire

There is actually.

<ma-file-store-browser ng-init="maFileStoreBrowserModel = '/rest/v2/file-stores/default/your-folder-name/'" ng-model="maFileStoreBrowserModel" store="default" disable-edit="true"></ma-file-store-browser>

psysak

Just quickly, in reading ng-model is a form input correct?

Is there an ng output of any kind from this component that I could look at? There are no docs in either the API or regular documentation sections for it.

ng-model defines the underlying data of a view. Basically in this case the model data is a string which defines the path to a file. If you select a different file in the browser it will update the model variable with the new path.

I don't know what a ng output is however you can view any variable in your scope like so

<pre ng-bind="maFileStoreBrowserModel | json"></pre>

Correct, this component was not originally intended for customer use.

psysak

Quick question, permissions can't be set on a folder in a filestore can they?

Jared Wiltshire

No permissions are per file store.

psysak

Hey guys, I was wondering if I could get your help on this a little bit. In light of not being able to lock down individual files is there any other way, either in mango or through the use of the Angular framework or anything else, which would allow me to implement a file download? Main thing is I need to basically lock a user out from easily getting to other people's files.
I suppose let me ask a different question as well. Will mango have an issue if I create a hundred filestores? I'm not sure I'll need 100 but let's say I did.
I also do realize I could probably link to an FTP, but that makes a much less seamless experience. I like the file store as well because I can just drop files and they appear. If I had a table or whatever I'd have to traverse a directory and build links dynamically and I'm not great with how to accomplish that.

Thanks all, I'm a bit up against it here on this one.

It should be totally fine to have hundreds of file stores.

The file stores weren't really intended to be per user but per "group" / "role"

psysak

OK that's fair, I would consider this implementation an instance of "group/role of one" :)
Thanks that helps!

I chuckled a little too hard on that comment!

Hi guys,

I have a user with only edit-ui-pages role and I have add edit-ui-pages role into flle stores' edit menu page as such:

However, when I login with the new user, the user can only see the file stores > default directory. The user cannot add files or directory to the default directory. Furthermore, the user cannot access the file stores > public directory. What else do I need to setup so the user can access the file stores' public directory?

Please advise.

BR,
Ricardo

Check filestore permissions under
administration->system-settings->permissions
for a start.
