I created a FreeMeal tab in my DB; this tab has a foreign key on the User tab. When I use the form in Active Admin to create a new entry of FreeMeal, I get a list of all my users for the user input; but users aren't displayed the right way, like so:
edit: the form is automatically populated as I have the foreign key on users. I simply have the following code for this form in app/admin/free_meals.rb:
ActiveAdmin.register FreeMeal do
form do |f|
f.inputs "FreeMeal" do
f.input :user
f.input :reason
end
f.actions
end
end
I would like to have this list with my users' id, first_name and last_name.
How can I do that ?
Try this:
f.input :user, as: :select, collection: User.all.map{ |u| ["#{u.id}, #{u.first_name} #{u.last_name}", u.id]}, multiple: false

First off, I am using Devise, Cancan, Role Model, and simple_form. Everything seems to work with permissions and whatnot. What I can't seem to do is create a form so that I can assign roles to Users.
Here is what I have so far:
<%= simple_form_for(#profile.user) do |f| %>
<%= f.input :roles_mask, as: :check_boxes, collection: User.valid_roles, :checked => [ 'member' , true] %>
<%= f.button :submit %>
This shows the check boxes properly, and the last part flags one as true. I'm not sure how to get it to flag the roles that are supposed to be flagged. I chose one at random for testing Also, if I send it to update, nothing seems to happen. I updated like I normally would limiting my params to just the roles_mask variable.
def update
if #user.update(params.require(:user).permit(:roles_mask))
flash[:notice] = "Permissions updated."
redirect_to profile_path(#user.profile_id)
else
render 'edit'
end
I have no clue what I am doing wrong. Even if I could just get them to update. Not showing the current roles isn't a huge deal.
You don't need to directly access roles_mask property, just assign roles property with the array of roles. Example:
= f.input :roles, collection: User.valid_roles, as: :check_boxes, checked: #user.roles, label_method: proc {|l| User.human_attribute_name(l) }
And don't forget to permit that form value for strong parameters:
params.require(:user).permit(roles: [])
I'm trying to manually tell formtastic to check a few checkboxes. #some_array currently has an element called checked which exists for each member.
= f.input :cboxes, label: "CBoxes", as: :check_boxes,
collection: #some_array.map { |a| [a[:name], a[:id]] }
I've tried to set the input_html to { checked: 'checked' } (How to pre-check checkboxes in formtastic) but this checks all checkboxes, not just the select few that I want.
The contents of #some_array are coming via an API, and I can't change the database structure (Ruby on Rails + Formtastic: Not checking checkboxes for multiple checked answers)
Suggestions?
If you are editing an ActiveModel, you don't need to "manually select checkboxes".
Let's consider a simple example with a single User model which has fields username and roles. Roles field is a string column, which Rails serializes as an Array. It might also be has_many relation to other ActiveModel, but we assume it's an Array for simplicity.
User is defined in user.rb:
class User < ActiveRecord::Base
serialize :roles, Array
end
Now you can "assign manually" desired roles to User in your controller:
#user = User.new(username: 'dimakura', roles: ['admin', 'editor'])
and define form in your view:
<%= semantic_form_for #user do |f| %>
<%= f.input :username %>
<%= f.input :roles, as: :check_boxes, collection: ['owner', 'admin', 'editor', 'viewer'] %>
<% end %>
In given example only "admin" and "editor" roles will be pre-selected in form. The "owner" and "viewer" role won't be selected.
Update Official documentation states:
Formtastic, much like Rails, is very ActiveRecord-centric.
But actually it's not a big challenge to create ActiveRecord-compatible model yourself. An example of doing this can be found in this blog post.
I need to create a dropdown field(membership_code), whose values are contained on a different table called members.
Schema
prereg
id
membership_code(string) not a foreign key
verification_code
members
id
membership_code
Prereg Active Admin Model
ActiveAdmin.register Prereg do
form do |f|
f.inputs "Preregistered Users" do
f.input :verification_code
f.input :email
#THIS LINE NEEDS TO BE CHANGED TO LIST DOWN THE MEMBERSHIP_CODE FROM MEMBERS
# f.input :membership_code, :as => :select, :collection => Members.all()
end
f.actions
end
To add, I was planning to have this logic wherein whenever you create a Prereg record, the selected "membership_code" would be deleted from the members.membership_code list.
How is this done in ActiveAdmin? Sorry I haven't found any good resource for DB Hooks and I'm still new to Rails.
I think you are looking for something as follows:
f.input :membership_code, as: :select, collection: Member.all.map(&:membership_code)
try this
f.input :membership_code, :as => :select, :collection => Members.select(:membership_code)
Thanks
I'm building a simple form to let users of my rails 4 site message each other.
In the form, the user can select the recipient of the message with a select list of all the users in the system (it's a small user base).
Right now the form control looks like this, and works fine:
<%= f.select(:to_id, options_from_collection_for_select(User.all, :id, :first_name), {}, {:class => 'form-control'}) %>
However, there's a "nickname" field in the Users table as well-- I'd like to have the form show the nickname (if it exists) as well as the user's first / last name-- so the value of the select would be:
<option>Snoop Dogg - Calvin Broadus</option>
rather than just
<option>Calvin</option>
Is this possible?
Make a display_name on the Users model
def display_name
nickname || first_name
end
Then update your form to reference it
<%= f.select(:to_id, options_from_collection_for_select(User.all, :id, :display_name), {}, {:class => 'form-control'}) %>
I have two related models, Bunny has_many BunnyData (which belongs_to Bunny). From the show page of a particular Bunny (in Active Admin), I want to create a link to make a related BunnyData. I've tried a few different ways, with no success, and am currently trying this:
sidebar :data, :only => :show do
link_to 'New Data', new_admin_bunny_datum(:bunny_id => bunny.id)
end
The link being generated ends up as something like:
.../admin/bunny_data/new?bunny_id=5
But when you go to that page, the dropdown for Bunny is set to the blank default as opposed to showing the name of Bunny with ID 5.
Thanks in advance.
Rails namespaces form fields to the data model, in this case BunnyData. For the form to be pre-filled, any fields provided must also include the namespace. As an example:
ActiveAdmin.register Post do
form do |f|
f.inputs "Post Details" do
f.input :user
f.input :title
f.input :content
end
f.actions
end
end
The fields can be pre-filled by passing a hash to the path helper.
link_to 'New Post', new_admin_post_path(:post => { :user_id => user.id })
Which would generate the following path and set the form field.
/admin/posts/new?post[user_id]=5
In the case of BunnyData, it might be slightly different due to the singular and plural forms of datum. But that can be verified by inspecting the generated HTML to find the name attribute of the inputs.
