UI: Allow for specification of max length of text box and text area in service dialog element creation

[Cameronwyatt]

Currently the max length allowed for both text boxes and text areas is hard coded. The values are 50 for a text box and 8196 for a text area. They can be found at vmdb/app/views/miq_ae_customization/_dialog_field_form.html.haml on lines 60 and 49 respectively.

The max length can be too short for a text box, and unnecessarily long for a text area. One of the main issues I have run into with the max length of the text boxes is that URLs can easily be longer than 50 characters. The reason that we want the URLs to be entered in a text box instead of a text area is that a text area will allow for newline characters, which can cause issues if the input is not sanitized correctly. Currently the ability to add a validator rule to a text area (like with a text box) is not implemented.

Max length should be added as an optional field in the "Options" box when creating a new service dialog element. If no value is specified, keep the default.

@gmcculloug @dclarizio Please take a look.

Completely agree that we need to expose this property in the dialog editor. To take it a step further we might want to also expose a minimum length as well. While this could be achieved through the regex validation rule we would be able to provide a better error message if it was based off a separate field property.

We are seeing the same requirement coming from other integrations like AWS Cloudformation and Openstack Heat.

Looks like a good enhancement and it will then enforce the max when creating the element on the screen as well.

Hi,

Is this available now? I have a use case that require more than 50 characters on a textbox.

Weird that this issue is already reported in 2014 and since than nobody has done something about it.
There is a bug report for this at CloudForms Bugzilla too but nobody seems to be interested to fix this either: https://bugzilla.redhat.com/show_bug.cgi?id=1539507

@eclarizio can you provide an update on this issue.

[eclarizio]

@JPrause as @romanblanco mentioned in the referenced PR, the way that all new dialogs are rendered is through the dialog-user component in the ui-components repository where the max length is no longer limited.

Thanks @eclarizio
