Error- When assigning attributes, you must pass a hash as an argument

I have a funding table below is its admin funding show page. I want to add a feature so that the admin can add the cheque cut date directly from this page with a submit button at the end.

<%= form_tag add_cheque_date_path, :method => 'patch' do %>
<tbody>
<% @fundings.each do |funding| %>
<tr>
<td><%= funding.child.parent.parent_1_firstname %></td>
<td><%= funding.child.parent.email %></td>
<td><%= funding.activity_start_date %></td>
<td><%= funding.date_submitted %></td>
<td><%= funding.status %></td>
<td><%= date_field_tag "funding.cheque_cut_date", funding.cheque_cut_date %></td>
<td><%= link_to "View", parent_child_funding_path(funding.child.parent, funding.child, funding) %></td>
</tr>
<% end %>
</tbody>
</table>
<%= submit_tag "Submit" %>
<% end %>


parents_controller.rb

def add_cheque_date
@fundings= Funding.all
fundings = params[:fundings]
@fundings.each do |funding|
funding.update_attributes(:cheque_cut_date)
end
end

def funding_params
params.require(:funding).permit(:cheque_cut_date)
end


routes.rb

patch 'admin/application-status', to: 'parents#add_cheque_date', as: 'add_cheque_date'


When I click on submit below is the error i am getting. Kindly help me fix it.

update_attributes updates all the attributes from the passed-in
Hash and saves the record. If the object is invalid, the saving will
fail and false will be returned.

update_attributes

But at funding.update_attributes(:cheque_cut_date) you put only key :cheque_cut_date without any value. Try next:

funding.update_attributes(:cheque_cut_date)

:cheque_cut_date

funding.update_attributes(funding_params)


Also, there is more than one problem. date_field_tag "funding.cheque_cut_date" create field with the name funding.cheque_cut_date, but params.require(:funding).permit(:cheque_cut_date) not permit key funding.cheque_cut_date. Change your fields name too:

date_field_tag "funding.cheque_cut_date"

funding.cheque_cut_date

params.require(:funding).permit(:cheque_cut_date)

funding.cheque_cut_date

<td><%= date_field_tag "funding[cheque_cut_date]", funding.cheque_cut_date %></td>

#or the same fields helpers type as other from this form
<td><%= f.date_field :cheque_cut_date %></td>


form.html.erb

<td><%= date_field_tag "cheque_cut_date[#{funding.id}]", funding.cheque_cut_date, min: Date.today %></td>


controller.rb

def add_cheque_date
fundings = params[:cheque_cut_date]
fundings.select do |k, v|
if v.present?
funding = Funding.find(k)
funding.update_attributes({cheque_cut_date: v})
end
end
end
