Issue to show data from relational database

Ruby
1

I want to show data from two tables these are

applied_jobs table: it contains the below columns:

applied_jobs_id | jobseeker_id | expected_salary

jobseekers table: it contains the below columns:

jobseeker_id | year_of_experience | name

My view file codes:

 <tbody>
    <% @applicants_view.each do | applicants | %>
      <tr>
        <td><%=  applicants.jobseeker.name%></td>
        <td><%=

applicants.jobseeker.year_of_experience %>

<%= applicants.expected_salary %> 
       </tr>
     <% end %>
  </tbody>

My controller codes:

def applicantsList

   @applicants_view = AppliedJob.paginate(page: params[:page],

:per_page => 4).order(‘applied_jobs_id DESC’)

end

My applied_job model codes:
class AppliedJob < ActiveRecord::Base

    belongs_to :jobseeker
end

My jobseeker model codes:

class Jobseeker < ActiveRecord::Base

    has_one :applied_job

end

When I try to show data it’s showing the below error

Showing

where line #51 raised:

  undefined method `name' for nil:NilClass

Someone can help me, please to identify where the bug?

One of your applicants has no jobseeker, it’s returning nil on
applicants.jobseeker

I have solved this issue by adding

<% @applicants_view.each do | applicants | %>
<% applicants.jobseeker.try(:name) %>
…
<% end %>

anyone suffer this type of problem then it will be helpful.
