EasyAdminBundle re-uses all the form stuff... but also comes with one new form
field... and it's pretty bananas! From the main documentation page, click
Edit and New Views Configuration. Down a ways, find
a section called "Autocomplete". Ah, lovely! This is a lot like the EntityType...
except that it renders as a fancy AJAX auto-complete box instead of a select drop down.
Right now, the subFamily field is a standard EntityType. But, it doesn't look
that way at first... it's fancy! And has a search! We get this automatically thanks
to some JavaScript added by EasyAdminBundle. It works wonderfully... as long as
your drop down list is short. Because if there were hundreds or thousands of sub
families... then all of them would need to be rendered on page load... which will
really slow - or even break - your page.
Let's use the autocomplete field instead. Expand the subFamily configuration and
set type: easyadmin_autocomplete:
| ... lines 1 - 80 | |
| easy_admin: | |
| ... lines 82 - 91 | |
| entities: | |
| Genus: | |
| ... lines 94 - 114 | |
| form: | |
| fields: | |
| ... lines 117 - 124 | |
| - { property: 'subFamily', type: 'easyadmin_autocomplete' } | |
| ... lines 126 - 138 |
That is all we need: it will look at the subFamily field and know which entity
to query. So.... it just works! Watch the web debug toolbar as a I type. Ha!
There be AJAX happening!
Next, let's add a CollectionType to our form.
Hey Philippe Gamache
Do you get any error logs on your console? We need to debug this a bit further
Cheers!
Hi Ryan, I get an error : "The required option "class" is missing.". I've googled this problem, and it happens when you do not have a __toString() method in your entity, but I do have that.
Do you have any clue why this may happen?
My code in config.yml: "- { property: 'createdBy', type: 'easyadmin_autocomplete' }"
Best regards,
Dennis
Hey Dennis,
Hm, if exactly this line causes that error - how is this createdBy field mapped in your code? I see we don't have such field :) I assume that createdBy is a User object, and you need to have a __toString() method in the User class, not in Genus. Otherwise, specify the "class" option explicitly.
Cheers!

The Dropdown or autocomplete doesn't close when I used them. Do you have any idea?
