Using auto-generated titles against entry field type values

Question

How would you setup a section's entry type to auto-generate the titles based on the title (or slug) of another entry?

For example, we have a Software section with entries. We also have a Releases section. Each release entry has a related software entry, along with a versionNumber text field.

Ideally each release's title would be of the form :

{software.title} {versionNumber}

Where {software.title} is the title from associated entry.

We've looked at all sorts of combinations to get that value out, but any usage seems to either be ignored or throw an error on publish.

Answer 1

You can access the Software entry’s title exactly the same way you would in your front-end templates: software.first.title. The only difference is the single-brace tags syntax, which you don’t even have to use if you don’t want to. Both of these are identical:

• {software.first.title}
• {{ object.software.first.title }}

Answer 2

The "Inherit Title" plugin might work for you but you will have to test it for your needs. It hides the title field and then uses the content of other fields in the entry to automatically generate the title for you.

From the read.me:

Say you have a "firstName" and "lastName" field, and you would like the Title to auto populate with "firstName lastName" you could use: "{{firstName}} {{lastName}}" as your settings configuration.
