I have a country list that I have called in - and have parsed into the following format:
{"Countries"=>[{"Name"=>"ABKHAZIA", "IsoCode"=>"AB", "HasTown"=>"I"}, {"Name"=>"ANGUILLA", "IsoCode"=>"AI", "HasTown"=>"I"}, {"Name"=>"ANTIGUA", "IsoCode"=>"AG", "HasTown"=>"I"}, .... {"Name"=>"ZIMBABWE", "IsoCode"=>"ZW", "HasTown"=>"I"}]}
I want to populate a drop down list with this data. Code I am using to create the drop down box is:
def country_selection_input options = {}
options.reverse_merge!(
:attribute => :country_iso,
:collection => transaction_form.get_countries,
:input_html => {},
:prompt => 'please select',
:label => 'To Where'
)
This gives me a drop down box with a please select prompt and a list that consists of only the one word: Countries.
The data is there - but I am not sure how to get it into the drop down list - and am sure I am missing something simple.
I have tried
:label_method => :Name,
but get an error message of
undefined method `Name' for #<Array:0x007fc385cecbb0>
This will probably turn into a menu as I want to take action based on the country selected - but - this is the first step - getting the list to work.
The answer ended up being
def country_selection_input options = {}
countries = transaction_form.get_countries()[:Countries]
options.reverse_merge!(
:attribute => :country_iso,
:collection => countries,
:label_method => :Name,
:value_method => :IsoCode,
:input_html => {},
:prompt => 'please select',
:label => 'To Where'
)
call_input_from_args_hash options
end

I have a collection, I am showing to the user.
But I need to I18n.translate the :key into a readable text from my de.yml.
competences:
key:
compkey001: "Werbung / 360"
compkey001subkey002: "Klassische Werbung / ATL"
compkey002: "Strategie"
f.input :competence_id, label: "Kompetenz", :as => :select,
:collection => option_groups_from_collection_for_select(
#competence_kategories, :competence_unterkats, t(:key,
scope: 'basic_data.competences'), :id, t(:key,
scope: 'basic_data.competences'))
This is not working.
It is giving me an error, something like: t() is not a method.
The below line is working, but showing the keys that are not usable by the user:
f.input :competence_id, label: "Kompetenz", :as => :select,
:collection => option_groups_from_collection_for_select(
#competence_kategories, :competence_unterkats, :key, :id, :key)
Displayed will be:
(bold)compkey001
compkey001subkey001
(bold)compkey002
... etc.
How can I get the translations being displayed in a grouped manner?
Thanks for help!
I am trying to set up a group of radio buttons in rails using simple_form. The options should come from a map.
In simple form, I saw there the :collection symbol can retrieve a collection (but only an array of arrays and not a hash).
How can I display a radio button collections with custom labels (ideally from a hash)?
Here is what I tried so far. Can I concatenate the symbol with an a string for a label?
#Payment.rb
OPTIONS = [[14, 19], [21,29], [30,39]] #ideally this would be a hash
#new.html.erb
<%= f.input :duration,
:collection => [ [14, 19.to_s], [21,29.to_s], [30,39.to_s] ],
:label_method => :last.concat(" days"),
:value_method => :first,
:as => :radio %>
if I understand your question correctly - you can use lambdas in :label_method. For example:
:label_method => lambda { |a| a.first.to_s + a.last.to_s }
I am trying to allow the user to be able to choose multiple records in a field on the search form.
Something like this:
<%= f.input_field :neighborhood_id, collection: Neighborhood.order(:name), :url => autocomplete_neighborhood_name_searches_path, :as => :autocomplete, 'data-delimiter' => ',', :multiple => true, :class => "span8" %>
It sends it to my search model like this: #search = Search.create!(params[:search])
This is what the Search.rb model does with it:
key = "%#{keywords}%"
listings = Listing.order(:headline)
listings = listings.includes(:neighborhood).where("listings.headline like ? or neighborhoods.name like ?", key, key) if keywords.present?
listings = listings.where(neighborhood_id: neighborhood_id) if neighborhood_id.present?
listings
The issue is that this is just accepting 1 neighborhood_id, so I am getting this error when I choose multiple objects:
undefined method `to_i' for ["Alley Park, Madison"]:Array
Where Alley Park and Madison are the names of 2 neighborhoods, not the IDs.
So how do I get this working?
Thanks.
Edit 1
The issue seems to not be in the lookup of the params[:search] per se, but rather in the conversion of the form input to an array of entries. I tried changing the search method to be something like:
listings = listings.includes(:neighborhood).where("neighborhoods.name like ?", neighborhood_id) if neighborhood_id.present?
Don't get hung up on the fact that I am looking up neighborhood.name and passing in neighborhood_id. I just did that because I know that the params for the field neighborhood_id were actually the names of the neighborhood. If this had worked, I would have refactored some stuff, but it didn't. So don't get hung up on that.
But that still returns the error undefined method 'to_i'....
Also, I still get that error even if I just pass in 1 option.
listings = listings.where("neighborhood_id in (?) ", neighborhood_id)
You can get the id instead of neighborhood names from the input field like this:
<%= f.input_field :neighborhood_id, collection: Neighborhood.order(:name), :url => autocomplete_neighborhood_name_searches_path, :as => :autocomplete, 'data-delimiter' => ',', :multiple => true, :class => "span8", :input_html => { :id => "neighborhood_id" } %>
I currently have a multiple select box in a rails form that looks like this:
= select_tag :in_all_tags, options_from_collection_for_select(Tag.where(:project_id => #project.id), :id, :name, #in_all_tags_param), { :id => "tags", :tabindex => "3", "data-placeholder" => "Choose Tags", :multiple => "multiple" }
Where
#in_all_tags_param = params[:in_all_tags]
The problem is, #in_all_tags_param will only populate the select form with the last value from params[:in_all_tags]. So, if the url string reads in_all_tags=5&in_all_tags=8, the pre-selected value in the multiple select will only be 8.
From what I understand, the way around this is to append [] to the field name for multiple params, so that :in_all_tags becomes in_all_tags[]
BUT, when I try this, submitting the form returns:
Expected type :default in params[:in_all_tags], got Array
Any suggestions appreciated.
Cheers...
You need to add a :name element to the same hash with :multiple => true in it. So I use something similar for Genres on an app for mine and I do { :multiple => true, :name => "lesson[genre_ids][]" }. The name has to be model[attribute][].
I came across the following on the simple_form github repo:
f.input :country_id, :collection => #continents, :as => :grouped_select, :group_method => :countries
The thing that caught my attention was the :group_method wich would be exceptionally usefull when creating a selectbox that gives options based on what's in the database. The only thing I can't work out is what kind of input the :group_method expects, and where to put the method.
For instance, I want to create a selectbox for the table column :product_type. I imagine I would write something like this in my simple form:
= f.input :product_type_contains, :collection => #products, :as => :grouped_select, :group_method => :product_types
where :product_type would be the method that is being called. But I don't know what kind of method I should write, what kind of result simple_form expects, and if I should put it in the Product class, Product.rb. Any help would be greatly appreciated!
According to the test suite, simple_form seems to expect the type of arrays or hashes that you would use with grouped_options_for_select:
test 'grouped collection accepts group_label_method option' do
with_input_for #user, :tag_ids, :grouped_select,
:collection => { ['Jose', 'Carlos'] => 'Authors' },
:group_method => :first,
:group_label_method => :last
[...]
test 'grouped collection accepts label and value methods options' do
with_input_for #user, :tag_ids, :grouped_select,
:collection => { 'Authors' => ['Jose', 'Carlos'] },
:group_method => :last,
:label_method => :upcase,
:value_method => :downcase
[...]
Presumably, you could write a class method on Product.rb that creates a structure similar, or even try using grouped_options_for_select(#products)...
Hope this gets you on the right path.
