Max length of Mailbox.uri field is too low

[eriktelepovsky]

Hello.

Is there a reason why the Mailbox.uri field is limited to 255 characters only? If you create Office 365 mailbox with uri formatted like described in documentation:

office365://youremailaddress%40yourdomain.com:oauth2@outlook.office365.com?client_id=client_id&client_secret=client_secret&tenant_id=tenant_id&archive=Archived

you will reach the limit of 255 characters very easily as client_id, client_secret and tenant_id values have together 112 characters.

Can you either increase the max_length value or change it to models.TextField instead?

Hi,
Thanks for your feedback.
I guess the only reason is that at some point max_lenght was a mandatory param, and 255 was the "default" value.

TextField is not an option (because of the multi line), and URLField is probably too strict (and will raise invalid scheme errors for office365:// scheme)
The only soluton seems to be to increase the max_length, (according to "standards" it should go up to 2048 characters...)

client_id, client_secret and tenant_id values have together 112 characters.

@eriktelepovsky is this total only the values or the param and their values?
I'm asking because the only variable part seems to be the email address, and maybe the mailboxes to fetch...
