I'm using her gem in my rails app to get data from a web service backend instead of a database. This question isn't completely related to the gem though is what I believe.
My model is using ActiveModel
class Merchant
include ActiveModel::Model
# Add the awesomeness of Her gem
include Her::Model
attr_accessor :name, :type
validates :name, presence: true
end
and my controller is
def create
@merchant = Merchant.new(params[:merchant])
if @merchant.valid?
respond_to do |format|
if @merchant.save
format.html { redirect_to @merchant, notice: 'Merchant was successfully created.' }
format.json { render :show, status: :created, location: @merchant }
else
format.html { render :new }
format.json { render json: @merchant.errors, status: :unprocessable_entity }
end
end
else
render :new
end
end
I have a form in my view like this
<%= form_for(@merchant) do |f| %>
<%= f.label :name, "First Name" %>
<%= f.text_field :name %>
<%= f.label :type, "Type" %>
<%= f.text_field :type %>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
Now here the attr_accessor :name, :type is needed inside the model for the form to function properly or its throwing this error
undefined method `name' for #<Merchant(merchants) >
If i add the attr_accessor in the Model then @merchant.attributes is returning {}.
and this leads to the gem sending blank request to server because the gem uses attributes to build the request. I checked in the source of the gem.
If i don't add attr_accessor then everything works fine except the form throws error.
What is way to fix this error. I'd be honest i don't clearly understand how attributes work.
The code suggests that if @merchant has an attribute called name, this won't happen:
class Merchant
include ActiveModel::Model
# Add the awesomeness of Her gem
include Her::Model
attributes :name, :type
validates :name, presence: true
end
