Administrate: Filtered scope for belongs_to

[tomgatzgates]

Is it possible (I've not currently found a way) to have the select dropdown for a belongs_to filter the available collection to the user.

For example. When editing and order which belongs_to an address, the dropdown would only show addresses that belong to the user.

I believe you can extend Field::BelongsTo and override candidate_resources to do this.

Admittedly this should be much easier. I've encountered this problem myself.

FWIW, I just pushed fishbrain/administrate-field-belongs_to_search to tackle the problem with the select drop down containing way too many records on belongs_to fields. It uses selectize to create a type-ahead search.

It might solve your problem too, @tomgatzgates. Feel free to try it out! Will publish it to RubyGems soon.

I tried to build my customized field class, but ran into a problem that the field object does not have the owner resource object.
https://github.com/thoughtbot/administrate/blob/e6ff1d6040a39de23330836312ecf6f8b12fcd70/lib/administrate/page/base.rb#L20

the dropdown would only show addresses that belong to the user.

It would be difficult because Field:BelongsTo has no way to get the owner resource user even if I extend and override candidate_resources.

Is there any suggested solution?

I found _form.html.erb has resource which I need.
I wrote custom field like this: https://gist.github.com/kuboon/cc57c3372669320112abd9044771c1de

It seems like this issue has two solutions, so I’m going to close this for now.

Please open an new issue if that’s not the case!

Thank you @klaseskilson for your gem administrate-field-belongs_to_search, exactly what I found missing in Administrate !
