anyone know of a quick example of how to change the field settings for a text area (plain) to formatted and set the input formatter (or maybe it will use default)? Will this require a resave of all the data or can it just be changed for the entity type? I currently have a lot of existing data on this site.

The field is currently stored as the type string, Text (plain). I need to change it to text_long, Text (formatted, long).



Attention for Drupal 8:

You need to update at least 3 or 4 yml files


(same change)

Maybe the last 2 ones you can deal with those changes on UI(go to each teaser and save). But I did in config folder.

  • While this will have changed the appearance of the node form, the data will not be saved correctly, and will not be displayed correctly. – Dalin Oct 24 '19 at 14:54

Oh wow, I just tried something in hopes of it being easy and it was a breeze!...

I already have all my config exported to code so I compared a text_long field to my current string_long field and just merged the differences, it worked beautifully. Something like the changes in the following example patch:

    I doubt it really just works like that. Note that the field type is also in the storage, and that changing the field type results in a different field schema, which drupal will actually prevent you from changing if you try it on the field storage config. – Berdir Oct 23 '16 at 11:12
  • @Berdir of course you are correct. Guess I am still looking to solve this. Seemed good at first but then I noted the display was rendering with html markup. – nicholas.alipaz Oct 24 '16 at 23:13
