In my new views page I have:
<% 10.times do %>
<%= render 'group_member_form' %>
<% end %>
Now this form contains the fields: first_name, last_name, email_address and mobile_number. Basically I want to be able to fill in the fields of all the forms in one click which then submits each into the database as a unique row/id.
What would be the easiest way to accomplish this?
Note: The number of times do is called from a variable. Any advice welcome, thanks!
You should have only one form (you should put only fields in the group_member_form partial). In your view you should have something like:
<%= form_tag "/members" do %>
<% 10.times do %>
<%= render 'group_member_form' %>
<% end %>
<%= submit_tag "Submit" %>
<% end %>
and in _group_member_form.html.erb you should have
<%= text_field_tag "members[][first_name]" %>
<%= text_field_tag "members[][last_name]" %>
<%= text_field_tag "members[][email_address]" %>
<%= text_field_tag "members[][mobile_number]" %>
This way, when the form submits, params[:members] in the controller will be an array of member hashes. So, for example, to get the email adress from the fourth member after submitting the form, you call params[:members][3][:email_adress].
To understand why I wrote _group_member_form.html.erb like this, take a glance at this:
http://guides.rubyonrails.org/form_helpers.html#understanding-parameter-naming-conventions.
You can also use accepts_nested_attributes_for in your model, and use fields_for on your form.
Submitting multiple forms, afaik, only javascript, if the forms are remote: true, and you run through each of them and then submit.
$("form.class_of_forms").each(function() {
$(this).submit();
});
Alternatively a more up to date approach using form_with and fields_for, without removing the form into a partial, could be written like this:
<%= form_with (url: end_point_path), remote: true do |form| %>
<% (1..5).each do |i| %>
<%= fields_for 'cart_items'+[i].to_s do |fields|%>
<%= fields.text_field :first_name %>
<%= fields.text_field :last_name %>
<%= fields.email_field :email_address %>
<%= fields.number_field :phone_number %>
<% end %>
<% end %>
<%= form.submit "Submit" %>
<% end %>
