Pass html table td value to rails controller - ruby-on-rails

Question

In my html I'm displaying some data from two tables. I provided an edit button for each row of the table. When I click on it, it has to check if the name is existing in table1 or table2 and take all the details of that particular name.
HTML:
<div class="col-md-12">
<h5 style="text-align: center;">List of SNMP OIDs</h5>
<table id="myPersonTable" class="table table-striped" >
<thead>
<tr>
<th>Person Name</th>
<th>Edit</th>
<th>Delete</th>
</tr>
</thead>
<tbody id="table_body">
<% #all_persons.each do |person|%>
<tr>
<td>
<%= person['name'] %>
</td>
<td>
<%= link_to '<button type="button" class="btn btn-info">Edit</button>'.html_safe, edit_oid_path(person['id'])%>
</td>
<td>
<%= form_tag(contoller: "configuration", action: "delete_person") do%>
<%= hidden_field_tag(:person_id, person['id'])%>
<%=submit_tag "Delete", class: "btn btn-danger", data: {confirm: "Are you sure?"}%>
<% end %>
</td>
</tr>
<% end %>
</tbody>
</table>
</div>
Rails Controller:
def edit
person_f = Person.find_by(name: params[:name])
person_s= HardPerson.find_by(name: params[:name])
if person_f.present?
#person = Oid.find(params[:id])
elsif person_s.present?
#oid = HardPerson.find(params[:id])
end
end
Here is a problem: I click on edit button for a person name from person2
table having id=1. This id exists in person1 and person2 tables both. Instead of taking details from person2 it is checking that id in person1 table and it is getting values for id=1 person details from person1 table
Here in controller params[:name] is getting null value. Help me to get params[:name] in my rails controller

Answer 1

To get params[:name] in your controller use the :param option in your routes to override the default resource identifier :id
resources :people, param: :name
This will allow you to use:
Person.find_by(name: params[:name])
Keep in mind that you might need to to override ActiveRecord::Base#to_param of a related model to construct a URL.
See 4.10 Overriding Named Route Parameters for more information.

Answer 2

It's a bit hard to understand what is your issue, but I'll try. Am I right that you want to see value from <%= person['name'] %> as a params[:name] inside edit action? Just pass it as additional argument to path helper:
<%= link_to '<button type="button" class="btn btn-info">Edit</button>'.html_safe,
edit_oid_path(person['id'], name: person['name'])%>
