More than one resource_admin to the same model

[mateuszbozek]

Hi ! Is it any possibility to create more than one admin resource to the same model ? Due to status (value of attribute (boolean) : true, false ) of objects in my model I need two menu items for managing of each parts of objects. Thanks for any answers.

I believe you can have as many admin pages to the same resource as pleased.
Used collection keyword to scope the model, like:4

#first_admin_page.rb
  collection do
    model.where(flag: true)
  end

#second_admin_page.rb
  collection do
    model.where(flag: false)
  end

You can easily with

app/admin/test_product_admin.rb
Trestle.resource(:test_product, model: Product)

app/admin/real_product_admin.rb
Trestle.resource(:real_product, model: Product)

And so on. Then you can limit data as stated above, permissions and behaviors. Using this way on production without any problems

I just faced admin_link_to issue when declaring multiple resources with model: User.
admin_link_to links to wrong resource, i would like to make one of them primary, and the others specialized/secondary, so admin_link_to links to primary resource.

Solved it with this ugly hack:

# app/admin/users_admin.rb
# put this code before Trestle.resource(:user)

# HACK: Ensure this admin module is registered as
#       primary User model page and admin_link_to User keep refering here.
#       Prevents conflict with YouNameConflictingAdminModule
Trestle.registry.instance_variable_get(:@models).delete('User')

In case your admin page is not about users - change it to your needs accordingly.

@Fedcomp Use the register_model: false option when declaring your secondary admin resource:

Trestle.resource(:secondary_users, register_model: false) do
  ...
end

This will ensure that this resource is not used for automatic model lookup when using the admin_link_to helper.
