How to create a custom field to upload files?

[Dubois]

Dear All

How can I create a custom field to upload a file in Jira?

The idea is to transfer a file from Jira to an external webservice.

Thanks.

Hi,

I think that this is exactly what you need: https://marketplace.atlassian.com/apps/1217971/file-field-document-field-for-jira

You install it without any setup and you can upload documents and files using a Jira customfield.

We have Data Center version and unfortunately doesn't work that plugin :(

Apwide File field plugin works perfectly well with Data Center version. As long as the data center approved version of an add-on is not available, Atlassian will let you use it in your Jira data center instances.

Hi all,

Great news: the data center version of Apwide File Field has been now officially tested and approved by Atlassian!

You can download it here: https://marketplace.atlassian.com/apps/1217971/file-field-attachment-document-field?hosting=datacenter&tab=overview

Enjoy your day, keep care,

A new field add-on is the right approach, but it's not going to be a trivial "simple custom field"

You will need to put a field on screen for capturing the incoming file somehow, which should be straightforward, as you'll just need to capture what the user says and call for their upload.

You probably want to have a second field to store your "reference id" (reusing the first capture field is not going to be easy, as you'll see the "view" code for it is called in places you don't expect, and edits would be a pain)

You're going to have to build an upload system to catch the incoming file and send it over to the other service.

You could simplify this a bit and drop the idea of using a field for the input - do it as an action instead, so a user can click something and get a box to ask questions, poke the file over and capture any reference given back which can then be added to a read-only custom field.I'm not aware of anything that already does anything like this with source code you could "borrow", all I can really do is point you to https://developer.atlassian.com/jiradev and say "look for p2 plugin development"

Thanks Nic. I will use your input and revert backwith more precise questions if necessary.

Do you really need a custom field? Can't the existing attachments feature be used for this?

Hello,

Thanks for your answer. No it does not fit our needs: we want to attach files using the attachments feature PLUS having a specific upload feature for some type of files. 

We want to have a special file to be transfered to external service. And make sure to differenciate this file as it is "special" for us. Not all files can be sent to the service.

The idea would be to have an <input type=file > field and intercept the stream to forward to our service, as well as saving a reference ID.

I'm new to Jira dev, but some boiler plates or guidelines would help a lot.
