passing array to f.select ruby on rails - ruby-on-rails

Question

On my rails application in the views/cards/_form i have the code for a f.select field:
<%= f.select :tag_speciality, options_for_select(#subdomain.tag_speciality), {}, {class: 'form-control'} %>
That give me the output:
<select class="form-control" name="card[tag_speciality]" id="card_tag_speciality">
<option value="Professor de Yoga">Professor de Yoga</option>
<option value="Professora de Yoga">Professora de Yoga</option>
<option value="Estúdio de Yoga">Estúdio de Yoga</option>
</select>
In my migration file i have:
add_column :cards, :tag_speciality, :string, array: true
When i go to the form and select any option, for example, "Professor de Yoga", and save, i get the result:
[]
instead of:
["Professor de Yoga"]
This is my controller:
def index
#cards = Card.all
end
def create
#card = #user.cards.new card_params
respond_to do |format|
if #card.save
format.html { redirect_to cards_from_subdomain_path(#subdomain.id), notice: 'Card was successfully created.' }
format.json { render :show, status: :created, location: #card }
else
format.html { render :new }
format.json { render json: #card.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #card.update(card_params)
format.html { redirect_to cards_from_subdomain_path(#subdomain.id), notice: 'Card was successfully updated.' }
format.json { render :show, status: :ok, location: #card }
else
format.html { render :edit }
format.json { render json: #card.errors, status: :unprocessable_entity }
end
end
end
# Never trust parameters from the scary internet, only allow the white list through.
def card_params
params.require(:card).permit(
:name,
:phone,
:email,
:cover,
:is_published,
:subdomain_id,
:domain_id,
:profile_id,
:is_solidarity,
:tag_speciality,
:tag_location,
user_id: []
)
end
end
Is there anything that am i missing?
Thanks

Ditto #EJ2015.
Just add
#card.tag_speciality.push(card_params[:tag_speciality])
#card.save
to your create.
respond_to do |format|
if #card.tag_speciality.push(card_params[:tag_speciality]) && #card.save
format.html { redirect_to cards_from_subdomain_path(#subdomain.id), notice: 'Card was successfully created.' }
format.json { render :show, status: :created, location: #card }
else
format.html { render :new }
format.json { render json: #card.errors, status: :unprocessable_entity }
end
end

Since your tag_speciality is an array column, you need to assign the data using array method in your controller.
#card.tag_speciality.push(card_params[:tag_speciality])
#card.save
Of course you need to modify the assignment of other attributes too. By the way, you can see what went wrong in your server log. In this case you should see that the database rejected commits.
