Blank multi-select

[JasperH8g]

I've got a basic has-many-through association:

project.rb:

    has_many :project_assets, :dependent => :delete_all, :autosave => true, :include => :asset
    has_many :assets, :through => :project_assets
    attr_accessible :asset_ids

project_asset.rb:

    belongs_to :asset
    belongs_to :project

asset.rb:

    has_many :project_assets, :dependent => :delete_all
    has_many :projects, :through => :project_assets

I can add new assets through this successfully, but the left part of the multi-select remains blank, so I can't select assets that are already in the model. What could be the reason for this?

[mshibuya]

This is expected behavior when you have many assets(more than 100 by default).
You need to fill search box above the left pane, and matching assets will be shown in the left pane, retrieved via Ajax request.

Thanks for your answer. I think though, that there should be some indication for the user that this is the case, and it's not plain broken in some way.

[mshibuya]

Agreed. That'll be less confusing.

@mshibuya how is this issue's status? Is there a way to force an initially populate in the field?

[JasperH8g]

Ha! Just experienced the exact same problem and found this thread again. Is there any progress on this issue? I'd like to do it myself, but I'm not sure when I'll find the time.

This is a usability issue, can there be some sort of warning on the admin panel that they have to use the search instead, spent a few hours debugging a non-issue.

it also affects rails_admin has_and_belongs_to_many relationships.

Spent 2 hours trying to figure out why my associations weren't showing up. They were defined correctly, it was just this issue.

[redterror]

Just wanted to pile on here - I'd really like to avoid explaining to my users that this isn't really a bug. :)

[daybreaker]

Throw one more on the pile of people who just spent way too long on this "issue" when all we need is a simple note somewhere around the search box. We have customer service reps who will be using this, and they probably wont remember the required functionality if they infrequently access that part of the edit form.

[mshibuya]

How do you think the note should be read? I couldn't come up with a concise phrase...

[JasperH8g]

What actually needs to be done is some automatic paging inside the list and xhr-based searching.

I'm not familiar with the RailsAdmin-codebase, so maybe someone who is can tell us if there already is some infrastructure in place to do something like this?

Personally I would really like it if the multi select box was disabled and the body said something like "Too many objects, use search box above." (Maybe just "Use search box above." so it fits on one line.)

And if you type a query in and there are no results it would stay disabled and read "No objects found."

It took me a while to find this post. I encountered the same issue.

[mshibuya]

Added note as described above, thanks @zenkalia !

[JasperH8g]

Excellent news! 👍

@mshibuya This problem still exists. How to help users to understand that he needs to type on input field?

[mshibuya]

What version are you on?
Can you reproduce that in brand-new app?

[modreoci]

Hmm... I'we got exactly the same problem like

There are many records matched search criteria.
Here is part of my Gemfile.lock:

    rails_admin (0.8.1)
      builder (~> 3.1)
      coffee-rails (~> 4.0)
      font-awesome-rails (>= 3.0, < 5)

What now?

[amicming]

@modreoci, I reproduced also with Rails 4.2.7.1 and rails_admin 0.8.1

[modreoci]

@amicming have you got any solution? Because here is about half a year no response... :-(

[michel-victor]

Hi @mshibuya. I have the same problem but with the filtering-select. When I have more than 100 items it doesn't load anything. It works with associated_collection_cache_all true but the load is huge. I loved the solution for the multi-select. Could you replicate it in the filtering-select? Thanks for the great job on RailsAdmin.
