How would one write a compare condition to check attachment extensions?

[Deleted user]

Is it possible to configure a compare condition to match only certain file extensions?  We'd like to create a rule that does the following:

When:  Value changes for Attachment

If:  Compare two values (If the attachment is .xls or .xlsx)

Then:  Automatically assign to a specific user.

---------------------

I thought it might work with the following but I can't seem to get it to function:

First value:  {{#issue.fields.attachments}}{{filename}},{{/issue.fields.attachments}}

condition: Contains

Second value:  xls

--------------------------

Any guidance would be appreciated.

Hey Sean,

This can be done using the following.

First value:

{{fieldChange.toString}}

This will print out something like: your-file.xls

Then use "matches regular expression"

Then use this as the regex:

^.*\.(xls|xlsx)$

Then simply add the Assign issue action to assign it the specifid user.

Hope this helps.

Cheers,

Nick
